Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab, shows the irregular dwarf galaxy Sextans A, which lies around 4.4 million light-years from Earth. This galaxy, which is only a fraction of the size of the Milky Way, has been contorted by successive waves of supernova explosions into the roughly square shape we see from Earth — a cosmic jewelry box filled with bright young stars. Sextans A is displayed in style in this gorgeous image, which showcases the irregular shape of this dwarf galaxy. Irregular galaxies such as Sextans A don’t have the regular appearance of spiral or elliptical galaxies, but instead display a range of weird and wonderful shapes. These galaxies are relatively small, and they are often susceptible to distortions resulting from close encounters or collisions with larger galaxies — sometimes leading to their irregular shapes. Sextans A is particularly small, measuring only about 5000 light-years across.

With Webb’s excellent sensitivity to infrared light and the hours of exposure time combined in this image, distant galaxies (red colours) are brought out of the darkness. Other galaxies glow strongly from the abundance of light they radiate. These observations come from the CANUCS survey (#1208, PI: C. J. Willott). The survey employed Webb’s advanced instruments, including NIRCam, NIRISS and NIRSpec, to capture detailed images and spectra of massive galaxy clusters in infrared light. Astronomers could then study low-mass galaxies in these early clusters at early stages of evolution. Because of how Webb’s instruments work, for each cluster the survey targeted both the cluster’s centre, where the brightest and largest galaxies are gathered, and a “parallel field” of a neighbouring area within the cluster. This image features one of these parallel fields. Researchers studying the data from the CANUCS survey uncovered a distant galaxy, named CANUCS-LRD-z8.6, in this parallel field. The galaxy is extremely distant (seen only 570 million years after the Big Bang) and the team’s research revealed that it hosts a supermassive black hole that is unusually large for such an early stage in the Universe. This result challenges existing theories about the formation of galaxies and black holes in the early Universe. [Image description: An image of many glowing galaxies in deep space, in various shapes and colours, on a black background. There are some large, blue spiral galaxies, some large and pale white elliptical galaxies, and many orange and red, medium-sized galaxies. Even smaller galaxies, down to tiny faint spots, appear in all these colours.]https://hoyenelcosmos.com/wp-content/uploads/2025/11/lrd-canucs-lrd-z8.6-webb-galaxia-agn-cuasar-macs-j1149-punto-rojo-red-dot-lowres.jpgCANUCS-LRD-z8.6 in MACS J1149.5+2223This image shows the location of galaxy CANUCS-LRD-z8.6 in galaxy cluster MACS J1149.5+2223, as seen by Webb’s Near-Infrared Camera (NIRCam). CANUCS-LRD-z8.6 is part of a class of small, very distant and strikingly red galaxies called Little Red Dots (LRDs), which have been spotted in increasing numbers by Webb’s surveys of the early Universe. It is located in the constellation Leo (the Lion), and is seen by Webb just 570 million years after the Big Bang. With the help of Webb’s Near-Infrared Spectrograph (NIRSpec), researchers have confirmed an actively growing supermassive black hole in CANUCS-LRD-z8.6. Analysing the galaxy’s spectrum yielded an estimate of the black hole’s mass, revealing it to be unusually large for such an early stage in the Universe, and showed that CANUCS-LRD-z8.6 is compact and has not yet produced many heavy elements (a galaxy at an early stage of its evolution). This combination challenges existing theories about the formation of galaxies and black holes in the early Universe. [Image Description: The left side of this visual shows an image of many glowing galaxies in various shapes and colours, including spiral and elliptical galaxies, on a black background. A small box near the top of this image highlights a small collection of galaxies. This box is pulled out to the right side, showing the same area zoomed in to reveal its details up close. This region shows a small circular red galaxy in the centre, which is labelled “CANUCS-LRD-z8.6”.]2025-11-25T01:33:43+00:00monthlyhttps://hoyenelcosmos.com/2025/11/18/meerkat-radio-quimica-3i-atlas-senales-alienigenas/https://hoyenelcosmos.com/wp-content/uploads/2025/11/frb-meerkat-4-3-sarao-web-845x321-1.jpgFRB-Meerkat-4-3-sarao-web-845x321https://hoyenelcosmos.com/wp-content/uploads/2025/11/meerkat-stokes-i-spectrum-blue-for-robust-0-and-orange-for-robust-1-of-the-oh-main.pngMeerKAT-Stokes-I-spectrum-blue-for-robust-0-and-orange-for-robust-1-of-the-OH-mainhttps://hoyenelcosmos.com/wp-content/uploads/2025/11/meerkat-sarao-telescope-3.jpgMeerKAT SARAO Telescope 3https://hoyenelcosmos.com/wp-content/uploads/2025/11/meerkat-sarao-telescope-scaled-1.jpgMeerKAT SARAO Telescope scaled2025-11-19T03:50:55+00:00monthlyhttps://hoyenelcosmos.com/acerca-de/https://hoyenelcosmos.com/wp-content/uploads/2025/11/gemini_generated_image-2-yo.pngGemini_Generated_Image 2 yohttps://hoyenelcosmos.com/wp-content/uploads/2018/06/universemann.jpgBeyond The Starshttps://hoyenelcosmos.com/wp-content/uploads/2014/06/imgp1665a.jpgIMGP1665ahttps://hoyenelcosmos.com/wp-content/uploads/2014/06/imgp1663c.jpgIMGP1663chttps://hoyenelcosmos.com/wp-content/uploads/2014/06/tycho_brahe1.pngtycho_brahe12025-11-19T00:34:46+00:00weekly0.6https://hoyenelcosmos.com/2025/08/08/3i-atlas-agua-hubble/https://hoyenelcosmos.com/wp-content/uploads/2025/08/3i-atlas-swift-uv-agua-oh.png3I ATLAS Swift UV Agua OHhttps://hoyenelcosmos.com/wp-content/uploads/2025/08/a11-interestelar-objeto-trayectoria-2-3i-atlas.jpgA11 interestelar objeto trayectoria 2 3I ATLAShttps://hoyenelcosmos.com/wp-content/uploads/2025/08/interestelar-objeto-a11-trayectoria-1-3i-atlas-1.jpgInterestelar objeto A11 trayectoria 1 3I ATLAShttps://hoyenelcosmos.com/wp-content/uploads/2025/08/interestelar-objeto-a11-trayectoria-1-3i-atlas.jpgInterestelar objeto A11 trayectoria 1 3I ATLAShttps://hoyenelcosmos.com/wp-content/uploads/2025/08/3i-atlas-jewitt-hubble-2.jpg3I ATLAS Jewitt Hubble 2https://hoyenelcosmos.com/wp-content/uploads/2025/08/cometa-3i-atlas-hubble-esa-nasa-1.jpg3I/ATLASThis is a Hubble Space telescope image of the interstellar comet 3I/ATLAS. Hubble photographed the comet on 21 July 21 2025, when the comet was 365 million kilometres from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus. Because Hubble was tracking the comet moving along a hyperbolic trajectory, the stationary background stars are streaked in the exposure. [Image description: At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.]2025-11-17T20:48:40+00:00monthlyhttps://hoyenelcosmos.com/2025/07/05/descubren-el-tercer-visitante-interestelar-3i-atlas/https://hoyenelcosmos.com/wp-content/uploads/2025/07/interestelar-objeto-a11-trayectoria-2-3i-atlas-cuadro.jpgInterestelar objeto A11 trayectoria 2 3I ATLAS cuadrohttps://hoyenelcosmos.com/wp-content/uploads/2025/07/a11-interestelar-objeto-trayectoria-2-3i-atlas.jpgA11 interestelar objeto trayectoria 2 3I ATLAShttps://hoyenelcosmos.com/wp-content/uploads/2025/07/e.-guido-m.-rocchetto-j.-ferguson-a11pl3z-interestelar-objeto-3i-atlas.jpgE.-Guido-M.-Rocchetto-J.-Ferguson-A11pl3Z interestelar objeto 3I ATLAShttps://hoyenelcosmos.com/wp-content/uploads/2025/07/c2025-n1-not-atlas-a11-3i-interestelar-cometa-seccion.jpgcharset=Ascii ScreenshotScreenshothttps://hoyenelcosmos.com/wp-content/uploads/2025/07/3i-atlas-a11-interestelar-cometa-ttt-iaa.png3I ATLAS A11 interestelar cometa TTT IAAhttps://hoyenelcosmos.com/wp-content/uploads/2025/07/c2025-n1-not-atlas-a11-3i-interestelar-cometa-seccion1.jpgcharset=Ascii ScreenshotScreenshothttps://hoyenelcosmos.com/wp-content/uploads/2025/07/atlas-3i-comet-interestelar-virtual-telescope-3-seccion.jpgATLAS 3I comet interestelar Virtual Telescope 3 seccionhttps://hoyenelcosmos.com/wp-content/uploads/2025/07/cometa-interestelar-ilustracion-atlas-3i.jpgCometa interestelar ilustracion ATLAS 3I2025-11-17T20:47:52+00:00monthlyhttps://hoyenelcosmos.com/2023/06/24/el-webb-revela-desolador-panorama-en-trappist-1c/https://hoyenelcosmos.com/wp-content/uploads/2023/06/230110102813-nasa-toi-700-e-planet_exoplaneta.jpg230110102813-nasa-toi-700-e-planet_exoplaneta2025-11-17T20:38:50+00:00monthlyhttps://hoyenelcosmos.com/2023/06/21/estos-asteroides-podrian-poner-en-riesgo-a-la-tierra/2025-11-17T20:38:48+00:00monthlyhttps://hoyenelcosmos.com/2023/06/14/una-enana-ultrafria-revela-el-origen-de-sus-auroras/2025-11-17T20:38:47+00:00monthlyhttps://hoyenelcosmos.com/2023/06/05/ligo-regresa/2025-11-17T20:38:45+00:00monthlyhttps://hoyenelcosmos.com/2023/05/31/una-historia-de-messier-101-la-galaxia-del-molinete-y-la-ultima-supernova/https://hoyenelcosmos.com/wp-content/uploads/2023/05/messier_101-m101_galaxia_hubble_lowres.jpgMessier_101-M101_Galaxia_Hubble_LowRes2025-11-17T20:38:44+00:00monthlyhttps://hoyenelcosmos.com/2023/06/08/en-busca-de-senales-extraterrestres-en-el-corazon-de-la-via-lactea/https://hoyenelcosmos.com/wp-content/uploads/2023/05/gbt_seti_breakthrough_lisen_extraterrestre.jpggbt_seti_breakthrough_lisen_extraterrestrehttps://hoyenelcosmos.com/wp-content/uploads/2023/05/greenabank-ta_radiotelescopio_gbt_telescopio.jpggreenabank-ta_radiotelescopio_gbt_telescopiohttps://hoyenelcosmos.com/wp-content/uploads/2023/05/milkyway_buenavista_lowres.jpgPicture saved with settings embedded.Picture saved with settings embedded.2025-11-17T20:38:42+00:00monthlyhttps://hoyenelcosmos.com/2023/06/02/agujeros-negros-en-busca-de-los-eslabones-perdidos/https://hoyenelcosmos.com/wp-content/uploads/2023/05/hubble_wanderingblackhole_art_agujero_negro_nasa.pnghubble_wanderingblackhole_art_Agujero_Negro_NASA2025-11-17T20:38:40+00:00monthlyhttps://hoyenelcosmos.com/2023/05/18/parecen-cometas-pero-no-lo-son/2025-11-17T20:38:39+00:00monthlyhttps://hoyenelcosmos.com/2023/05/11/modelando-el-ojo-de-gato/https://hoyenelcosmos.com/wp-content/uploads/2023/05/ngc-6543_cat-eye-nebula-planetaria-ojo-gato-shape-modelo.pngngc-6543_cat-eye-nebula-planetaria-ojo-gato-shape-modelohttps://hoyenelcosmos.com/wp-content/uploads/2023/05/planetary-nebulae-1000px_nebulosas_planetarias.jpgplanetary-nebulae-1000px_nebulosas_planetariashttps://hoyenelcosmos.com/wp-content/uploads/2023/05/pia17351-apparentsizes-marsdeimosphobos-earthmoon-lunas-marte-comparacion.jpgpia17351-apparentsizes-marsdeimosphobos-earthmoon-lunas-marte-comparacionhttps://hoyenelcosmos.com/wp-content/uploads/2023/05/imagesasteroid1999jm8-aug06-apophis-asteroide-asteroid-radio.jpgimagesasteroid1999jm8-aug06-apophis-asteroide-asteroid-radio2025-11-17T20:38:37+00:00monthlyhttps://hoyenelcosmos.com/2022/07/22/mi-camino-hacia-el-webb-julien-girard/https://hoyenelcosmos.com/wp-content/uploads/2022/07/20220716_104830.jpg20220716_1048302025-11-17T20:38:34+00:00monthlyhttps://hoyenelcosmos.com/2022/07/21/un-extrano-y-silencioso-agujero-negro/https://hoyenelcosmos.com/wp-content/uploads/2022/07/20220720_192250.jpg20220720_192250https://hoyenelcosmos.com/wp-content/uploads/2022/07/screenshot-from-2022-07-21-00-06-02.pngscreenshot-from-2022-07-21-00-06-02https://hoyenelcosmos.com/wp-content/uploads/2022/07/eso2210a.jpgArtist’s impression of VFTS 243 in the Tarantula NebulaThis artist’s impression shows what the binary system VFTS 243 might look like if we were observing it up close. The system, which is located in the Tarantula Nebula in the Large Magellanic Cloud, is composed of a hot, blue star with 25 times the Sun’s mass and a black hole, which is at least nine times the mass of the Sun. The sizes of the two binary components are not to scale: in reality, the blue star is about 200 000 times larger than the black hole.  Note that the 'lensing' effect around the black hole is shown for illustration purposes only, to make this dark object more noticeable in the image. The inclination of the system means that, when looking at it from Earth, we cannot observe the black hole eclipsing the star.https://hoyenelcosmos.com/wp-content/uploads/2022/07/eso1816a2.jpgThe rich region around the Tarantula Nebula in the Large MagellaGlowing brightly about 160 000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, a satellite galaxy to our Milky Way. This image from VLT Survey Telescope at ESO’s Paranal Observatory in Chile shows the region and its rich surroundings in great detail. It reveals a cosmic landscape of star clusters, glowing gas clouds and the scattered remains of supernova explosions.2025-11-17T20:38:33+00:00monthlyhttps://hoyenelcosmos.com/2022/07/11/un-mar-de-galaxias-asi-es-la-primera-imagen-profunda-de-webb/https://hoyenelcosmos.com/wp-content/uploads/2022/07/webb-first-deep-field_3.jpgwebb-first-deep-field_3Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/webb-first-deep-field.jpgwebb-first-deep-fieldCúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_12.jpgjwst-deep-field_12Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_11.jpgjwst-deep-field_11Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_10.jpgjwst-deep-field_10Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_09.jpgjwst-deep-field_09Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_07.jpgjwst-deep-field_07Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/hubble-first-deep-field_07.jpghubble-first-deep-field_07Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/jwst-deep-field_05.jpgjwst-deep-field_05Cúmulo de galaxias visto por el Telescopio Webbhttps://hoyenelcosmos.com/wp-content/uploads/2022/07/hubble-first-deep-field_05.jpghubble-first-deep-field_05Cúmulo de galaxias visto por el Telescopio Webb2025-11-17T20:38:31+00:00monthlyhttps://hoyenelcosmos.com/2022/02/20/pulsares-para-detectar-ondas-gravitacionales/2025-11-17T20:38:29+00:00monthlyhttps://hoyenelcosmos.com/2021/07/19/el-corazon-de-la-radio-galaxia-mas-cercana/https://hoyenelcosmos.com/wp-content/uploads/2021/07/eso_centaurus_a_laboca.jpgESO_Centaurus_A_LABOCAColour composite image of Centaurus A, revealing the lobes and jets emanating from the active galaxy’s central black hole.

The Milky Way can be seen to stretch high above with Eta Carinae Nebula, a bright emission nebula, shown giving off its fiery red glow. Taken during the ESO Ultra HD Expedition.https://hoyenelcosmos.com/wp-content/uploads/2018/06/eso1312a_alma.jpgALMA array from the airThis image shows an aerial view of the Chajnantor Plateau, located at an altitude of 5000 meters in the Chilean Andes, where the array of ALMA antennas is located. The large antennas have a diameter of 12 metres, while 12 smaller antennas with a diameter of 7 metres make up the ALMA Compact Array (ACA). On the horizon, the main peaks from right to left are Cerro Chajnantor, Cerro Toco, and Juriques. This photo was taken in December 2012, four months prior to the ALMA inauguration.https://hoyenelcosmos.com/wp-content/uploads/2018/06/alma_moon_venus.jpgALMA_Moon_Venushttps://hoyenelcosmos.com/wp-content/uploads/2018/06/uhd_yuri_alma_ant_cc.jpgThe Milky Way above the antennas of ALMAVía Láctea sobre las antenas del Observatorio ALMA.https://hoyenelcosmos.com/wp-content/uploads/2018/06/uhd_otto_cc_alma.jpguhd_otto_cc_ALMAhttps://hoyenelcosmos.com/wp-content/uploads/2018/06/potw1414a_alma_meteoro.jpgCosmic fireball falling over ALMAThis beautiful new image, taken during a time-lapse set at the Atacama Large Millimeter/submillimeter Array (ALMA) is another dramatic Ultra High Definition photograph from the ESO Ultra HD Expedition. ALMA, located at 5000 metres above sea level on the remote and empty Chajnantor Plateau in the Chilean Andes, marks the second destination for the four ESO Photo Ambassadors [1] on their 17-day trip. The ambassadors are equipped with state-of-the-art Ultra HD tools to help them capture the true majesty of sights like the one pictured here [2] [3]. Some of the 66 high-precision antennas that comprise ALMA are visible here, with dishes pointed aloft, studying the cold clouds in interstellar space, and peering deep into the past at our mysterious cosmic origins. The spectacular javelin of light over the ALMA array is a shooting star, slicing through the image in a vivid streak of colours. Emerald green, golden and faint crimson hues blaze brightly as the meteor burns up as it enters the Earth’s atmosphere and makes its fiery voyage across the sky. As the high-speed fireball — which is, in reality, a small grain of rock from interplanetary space — interacts with the atmosphere it heats up, vapourising the surface layers of the meteor, which are left behind in a glowing trail. These trails disappear in just a few seconds, but are captured here at the click of a button. The brightest star in the constellation of Virgo (The Virgin), known as Spica, and our neighbouring planet Mars glow brightly in the centre of the image — cosmic spectators to this fiery descent as they rise above the horizon. The Ultra HD Expedition began in Santiago, Chile, on 25 March 2014. This image was taken on the team’s eighth night on the Chajnantor Plateau. They are currently at La Silla Observatory, ESO’s first astronomical installation in Chile, and tomorrow, after one last night, they will finally make the long journey home.

The array lets astronomers address some of the deepest questions of our cosmic origins.https://hoyenelcosmos.com/wp-content/uploads/2018/06/potw1253a_alma_circumpolar.jpgWhirling southern star trails over ALMABabak Tafreshi, one of the ESO Photo Ambassadors, has captured the antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) under the southern sky in another breathtaking image. The dramatic whorls of stars in the sky are reminiscent of van Gogh’s Starry Night, or — for science fiction fans — perhaps the view from a spacecraft about to enter hyperspace. In reality, though, they show the rotation of the Earth, revealed by the photograph’s long exposure. In the southern hemisphere, as the Earth turns, the stars appear to move in circles around the south celestial pole, which lies in the dim constellation of Octans (The Octant), between the more famous Southern Cross and the Magellanic Clouds. With a long enough exposure, the stars mark out circular trails as they move. The photograph was taken on the Chajnantor Plateau, at an altitude of 5000 metres in the Chilean Andes. This is the site of the ALMA telescope, whose antennas can be seen in the foreground. ALMA is the most powerful telescope for observing the cool Universe — molecular gas and dust, as well as the relic radiation of the Big Bang. When ALMA construction is complete in 2013, the telescope will have 54 of these 12-metre-diameter antennas, and twelve 7-metre antennas. However, early scientific observations with a partial array already began in 2011. Even though it is not fully constructed, the telescope is already producing outstanding results, outperforming all other telescopes of its kind. Some of the antennas are blurred in the photograph, as the telescope was in operation and moving during the shot. ALMA, an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ).

This makes them an ideal laboratory to study the earliest epochs of star formation. But at a price — they are often enshrouded by obscuring dust that hampers the correct interpretation of the observations.https://hoyenelcosmos.com/wp-content/uploads/2018/06/eso1817a.jpgArtist’s impression of a dusty starburst galaxyThis artist’s impression shows a dusty galaxy in the distant Universe that is forming stars at a rate much higher than in our Milky Way. New ALMA observations have allowed scientists to lift the veil of dust and see what was previously inaccessible — that such starburst  galaxies have an excess of massive stars as compared to more peaceful galaxies.https://hoyenelcosmos.com/wp-content/uploads/2014/06/hs-2012-01-a-large_web_30doradus.jpghs-2012-01-a-large_web_30Doradus2025-11-17T20:37:13+00:00monthlyhttps://hoyenelcosmos.com/donar/https://hoyenelcosmos.com/wp-content/uploads/2017/11/milkyway_silueta_nightsky.jpgMilkyWay_silueta_nightsky2025-11-17T20:37:11+00:00weekly0.6https://hoyenelcosmos.com/2017/08/29/barnard-150/https://hoyenelcosmos.com/wp-content/uploads/2017/08/alvaroibanez.jpgBardnar 150 - Álvaro Ibáñez PérezEsta foto es parte de nuestra galería en <a href="https://naricesdetycho.org/imagenes/barnard-150-filamentos-de-gas-y-polvo/" rel="noopener" target="_blank">"Barnard 150: filamentos de gas y polvo"</a>2025-11-17T20:37:09+00:00monthlyhttps://hoyenelcosmos.com/2017/08/16/agujeros-supermasivos-medusas/https://hoyenelcosmos.com/wp-content/uploads/2017/08/eso1725d_jellyfishs.jpgVisualisation of MUSE view of Jellyfish GalaxyEsta visualización muestra una galaxia medusa, usando datos del instrumento MUSE en los Very Large Telescope de ESO.

Red shows the glow from ionised hydrogen gas and the whiter regions are where most of the stars in the galaxy are located.https://hoyenelcosmos.com/wp-content/uploads/2017/08/eso1725a_jellyfish_galaxias.jpgEjemplo de una galaxia medusaEjemplo de una galaxia medusa (ESO)2025-11-17T20:37:07+00:00monthlyhttps://hoyenelcosmos.com/2017/08/15/astrofotografia-circumpolar/https://hoyenelcosmos.com/wp-content/uploads/2017/08/polos_celestes.jpgpolos_celestesLos polos celestes marcan el eje de rotación de nuestro planeta.https://hoyenelcosmos.com/wp-content/uploads/2017/08/seleccion-del-lugar_low.jpgSeleccion del lugar_lowUna vez que seleccionamos el panorama, podemos comenzar a disparar (Foto: GCM)https://hoyenelcosmos.com/wp-content/uploads/2017/08/ubicacion-del-polo-norte_low.jpgUbicacion del polo Norte_lowhttps://hoyenelcosmos.com/wp-content/uploads/2017/08/equipo-para-toma_low.jpgEquipo para Toma_lowEquipo que podemos utilizar para hacer fotografía circumpolar.https://hoyenelcosmos.com/wp-content/uploads/2017/08/circumpolar_low.jpgcircumpolar_low2025-11-17T20:37:05+00:00monthlyhttps://hoyenelcosmos.com/2017/08/11/fuegos-artificiales-de-verano-en-rosetta/https://hoyenelcosmos.com/wp-content/uploads/2017/08/summer_fireworks_on_rosetta_s_comet.jpgSummer_fireworks_on_Rosetta_s_cometMontaje de imágenes del cometa Comet 67P/Churyumov–Gerasimenko, desde la nave Rosetta (ESA).2025-11-17T20:37:03+00:00monthlyhttps://hoyenelcosmos.com/2017/08/09/relativistas-en-una-estrella/https://hoyenelcosmos.com/wp-content/uploads/2017/08/ann17051b_sgra_s2.jpgArtist's impression of the effect of general relativity on the ohttps://hoyenelcosmos.com/wp-content/uploads/2017/08/ann17051c_sgra_s2.jpgImage of the Galactic CentreThe central parts of our Galaxy, the Milky Way, as observed in the near-infrared with the NACO instrument on ESO's Very Large Telescope.

The star S2 will make a close pass around the black hole in 2018 when it will be used as a unique probe of the strong gravity and act as a test of Einstein's general theory of relativity.  2025-11-17T20:37:02+00:00monthlyhttps://hoyenelcosmos.com/2017/08/11/poner-a-punto-el-telescopio-armar-y-alinear/https://hoyenelcosmos.com/wp-content/uploads/2017/08/alineacion_2016_planetas_stellarium.pngAlineacion_2016_planetas_stellariumLa eclíptica es la línea marcada por el Sol en su movimiento aparente en el cielo.

The blue halo of material surrounding the galaxy indicates the expected distribution of the mysterious dark matter, which was first introduced by astronomers to explain the rotation properties of the galaxy and is now also an essential ingredient in current theories of the formation and evolution of galaxies. New measurements show that the amount of dark matter in a large region around the Sun is far smaller than predicted and have indicated that there is no significant dark matter at all in our neighbourhood.2025-10-20T23:16:19+00:00monthlyhttps://hoyenelcosmos.com/2025/10/20/orionidas-como-y-cuando-ver-la-lluvia-de-meteoros/https://hoyenelcosmos.com/wp-content/uploads/2025/10/eventos-octubre-orionidas-1.jpgEVENTOS OCTUBRE Orionidas 1https://hoyenelcosmos.com/wp-content/uploads/2025/10/meteoros-velada-pareja-observacion-salida-pareja.jpgmeteoros velada pareja observacion salida pareja2025-10-20T15:42:32+00:00monthlyhttps://hoyenelcosmos.com/2025/10/14/descubren-un-planeta-bebe-que-brilla-mientras-devora-gas-y-polvo/https://hoyenelcosmos.com/wp-content/uploads/2025/10/wispit-2b-proto-exoplaneta-disco-magallanes.jpgWISPIT 2b proto exoplaneta disco Magallaneshttps://hoyenelcosmos.com/wp-content/uploads/2025/10/color_image_zp_lp_zp_halpha_lrgb-wispit-2-b-exoplaneta.pngCOLOR_IMAGE_Zp_Lp_Zp_Halpha_LRGB WISPIT 2 b exoplanetahttps://hoyenelcosmos.com/wp-content/uploads/2025/10/wispit-2-b-closeup-final-exoplaneta.jpgWISPIT 2 b Closeup Final exoplanetahttps://hoyenelcosmos.com/wp-content/uploads/2025/10/wispit-2-b-exoplaneta-nasa.jpgWISPIT 2 b exoplaneta NASA2025-10-14T01:01:33+00:00monthlyhttps://hoyenelcosmos.com/2025/10/13/la-gravedad-y-los-campos-magneticos-en-el-nacimiento-de-estrellas-masivas/https://hoyenelcosmos.com/wp-content/uploads/2025/10/ngc-6334-magnetic-field-formacion-estelar-alma.jpgNGC 6334 Spitzer and ALMAThis image from NASA’s Spitzer Space Telescope shows a star formation region in molecular cloud NGC 6334, also known as the Cat's Paw Nebula. The colors correspond with emission at 3.6 microns (blue), 4.5 microns (green), and 8 microns (red). This cloud is actively forming massive stars, and is located in the constellation Scorpius, between 4,200 to 5,500 light-years from Earth. ALMA data overlaid on the image shows details of four specific areas that were observed (NGC6334I, NGC6334I(N), NGC6334IV and NGC6334V), revealing invisible forces of magnetism and gravity as they wrestle and shape the formation of stars deep within the giant molecular cloud. The color scale in the ALMA images represents the intensity of the dust emission at 1.3mm and the drapery lines represent the orientation of the magnetic field.

Located about 620 light-years away, this rogue planet is about 5-10 times more massive than Jupiter and doesn’t orbit a star. It is eating up material from a disc around it and, using ESO’s Very Large Telescope (VLT), astronomers have discovered that it is now doing so at a rate of six billion tonnes per second –– the fastest ever found for any kind of planet. The team suspects that strong magnetic fields could be funnelling material towards the planet, something only seen in stars. When the infalling material reaches the planet it heats up its surface, creating a bright hot spot. The X-shooter spectrograph on ESO’s VLT detected a marked brightening in mid-2025, and found a clear fingerprint that this was caused by infalling gas. The observations show that the planet is now accreting matter about 8 times faster than a few months before.2025-10-05T01:36:13+00:00monthlyhttps://hoyenelcosmos.com/2025/10/01/descubren-enorme-ola-de-estrellas-que-recorre-la-via-lactea/https://hoyenelcosmos.com/wp-content/uploads/2025/09/gaia_mapping_the_stars_of_the_milky_way_2.jpgGaia_mapping_the_stars_of_the_Milky_Way_2https://hoyenelcosmos.com/wp-content/uploads/2025/09/gaia_discovers_our_galaxy_s_great_wave_side-by-side-ondulacion-via-lactea.pngGaia_discovers_our_galaxy_s_great_wave_side-by-side ondulacion via lacteahttps://hoyenelcosmos.com/wp-content/uploads/2025/09/gaia_discovers_our_galaxy_s_great_wave_side-by-side-ondulacion-via-lactea-seccion-2.jpgGaia_discovers_our_galaxy_s_great_wave_side-by-side ondulacion via lactea seccion 22025-10-01T03:13:34+00:00monthlyhttps://hoyenelcosmos.com/2025/09/25/hubble-enana-blanca-devorando-exoplaneta/https://hoyenelcosmos.com/wp-content/uploads/2025/09/enana-blanca-pluton-disco.jpgArtist’s impression of a white dwarf and debris discThis artist’s concept shows a white dwarf surrounded by a large debris disc. Debris from pieces of a captured, Pluto-like object is falling onto the white dwarf. [Image description: An illustration showing a glowing white object in the upper left corner. This object is encircled by hundreds of thin, concentric, pale-yellow rings on an angle from bottom left to top right. The rings are palest closest to the central, glowing white object. A curving trail of gray, rock-like fragments marches across the right side, through the thin rings and joins the rings at far right.

This image is composed of exposures taken through four filters — red, green, blue and ultraviolet. As exposures are taken, the comet remains fixed in the center of the telescope’s field of view. However, the positions of the background stars change relative to the comet, causing them to appear as colorful streaks in the final image. See a version of the image where the stars have been “frozen” here. These observations of Comet 3I/ATLAS were conducted during a Shadow the Scientists program hosted by NSF NOIRLab. A full recording of the session can be found here.https://hoyenelcosmos.com/wp-content/uploads/2025/09/3i-atlas-gmos-s-2025-aug-gemini-noirlab-color-2.jpgGrowing Tail of Interstellar Comet 3I/ATLASA deep image of interstellar Comet 3I/ATLAS captured by the Gemini Multi-Object Spectrograph (GMOS) on Gemini South at Cerro Pachón in Chile, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. The image shows the comet’s broad coma — a cloud of gas and dust that forms around the comet’s icy nucleus as it gets closer to the Sun — and a tail spanning about 1/120th of a degree in the sky (where one degree is about the width of a pinky finger on an outstretched arm) and pointing away from the Sun. 3I/ATLAS is only the third confirmed interstellar visitor to our Solar System. The exposures tracked the comet as it traveled across the sky, and the final image is composed to freeze the stars in place during the observation. Two small colored trails from unrelated asteroids with a different motion from that of the comet can also be seen.

With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation. In stellar nurseries across the galaxy, baby stars are forming in giant clouds of cold gas. As young stars grow, the gas surrounding them collects in narrow, dusty protoplanetary discs. This sets the scene for the formation of planets, and observations of distant protoplanetary discs can help researchers understand what took place roughly 4.5 billion years ago in our own Solar System, when the Sun, Earth, and the other planets formed. IRAS 04302+2247, or IRAS 04302 for short, is a beautiful example of a protostar — a young star that is still gathering mass from its environment — surrounded by a protoplanetary disc in which baby planets might be forming. Webb is able to measure the disc at 65 billion kilometres across — several times the diameter of our Solar System. From Webb’s vantage point, IRAS 04302’s disc is oriented edge-on, so we see it as a narrow, dark line of dusty gas that blocks the light from the budding protostar at its centre. This dusty gas is fuel for planet formation, providing an environment within which young planets can bulk up and pack on mass. When seen face-on, protoplanetary discs can have a variety of structures like rings, gaps and spirals. These structures can be signs of baby planets that are burrowing through the dusty disc, or they can point to phenomena unrelated to planets, like gravitational instabilities or regions where dust grains are trapped. The edge-on view of IRAS 04302’s disc shows instead the vertical structure, including how thick the dusty disk is.

The result is a detailed view that reveals thousands of distant galaxies, some dating back to the earliest periods of cosmic history.The field shown here, known as the MIRI Deep Imaging Survey (MIDIS) region, was observed with the three shortest-wavelength filters of Webb’s Mid-Infrared Instrument (MIRI) for nearly 100 hours in total. This included Webb's longest observation of an extragalactic field in one filter so far, producing one of the deepest views ever obtained of the Universe. Combined with data from Webb’s Near-Infrared Camera (NIRCam), this image allows astronomers to explore how galaxies formed and evolved over billions of years. These deep observations have revealed more than 2500 sources in this tiny patch of sky. Among them are hundreds of extremely red galaxies — some of which are likely massive, dust-obscured systems or evolved galaxies with mature stars that formed early in the Universe’s history. Thanks to Webb’s sharp resolution, even at mid-infrared wavelengths, researchers can resolve the structures of many of these galaxies and study how their light is distributed, shedding light on their growth and evolution. In this image, the colours that have been assigned to different kinds of infrared light highlight the fine distinctions astronomers can make with this deep data. Orange and red represent the longest mid-infrared wavelengths. The galaxies in these colours have extra features — such as high concentrations of dust, copious star formation, or an active galactic nucleus (AGN) at their centre — which emit more of this farther infrared light. Small, greenish-white galaxies are particularly distant, with high redshift. This shifts their light spectrum into the peak mid-infrared wavelengths of the data, which are depicted in white and green.

Paw Nebula (NIRCam)To celebrate the NASA/ESA/CSA James Webb Space Telescope’s third year of highly productive science, astronomers used the telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region. This area is of great interest to scientists, having been subject to previous study by NASA’s Hubble and retired Spitzer space telescopes, as they seek to understand the multiple steps required for a turbulent molecular cloud to transition to stars. With its near-infrared capabilities and sharp resolution, the telescope “clawed” back a portion of a singular “toe bean,” revealing a subset of mini toe bean-reminiscent structures composed of gas, dust, and young stars. Webb’s view reveals a chaotic scene still in development: Massive young stars are carving away at nearby gas and dust, while their bright starlight is producing a bright nebulous glow represented in blue. This is only a chapter in the region’s larger story. The disruptive young stars, with their relatively short lifespans and luminosity, will eventually quench the local star formation process. The Cat’s Paw Nebula is located approximately 4,000 light-years away in the constellation Scorpius.

It is located 160 000 light-years away in the Large Magellanic Cloud, a small galaxy orbiting our own Milky Way. The inset shows new observations with ESO’s Very Large Telescope (VLT), which show that the original star died with two explosive blasts. The main image shows the VLT unit telescope used in these observations.https://hoyenelcosmos.com/wp-content/uploads/2025/07/supernova-doble-ia-enana-blanca-calcio-muse-vlt.jpgDistribution of calcium around the supernova remnant SNR 0509-67This image shows the distribution of calcium in the supernova remnant SNR 0509-67.5.

These are the expanding remains of a star that exploded hundreds of years ago in a double-detonation – the first photographic evidence that stars can die with two blasts. The data were captured with the Multi-Unit Spectroscopic Explorer (MUSE) instrument at the VLT. MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two layers indicate that the now-dead star exploded with a double-detonation.2025-07-03T23:42:59+00:00monthlyhttps://hoyenelcosmos.com/2025/07/01/asteroide-2024-yr4-luna/https://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroid-2024-yr4-moon-luna-probabilidad-2025-junio.jpgAsteroid 2024 YR4 Moon Luna probabilidad 2025 juniohttps://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroide-chelyabinsk-3.pngAsteroide Chelyabinsk 3https://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroide-chelyabinsk-6.pngAsteroide Chelyabinsk 6https://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroide-chelyabinsk-1.pngAsteroide Chelyabinsk 1https://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroide-chelyabinsk-5.pngAsteroide Chelyabinsk 5https://hoyenelcosmos.com/wp-content/uploads/2025/06/asteroide-chelyabinsk-4.pngAsteroide Chelyabinsk 4https://hoyenelcosmos.com/wp-content/uploads/2025/06/meteorite-chelyabinsk-lago.jpgmeteorite Chelyabinsk lagohttps://hoyenelcosmos.com/wp-content/uploads/2025/06/impacto-asteroide-2024-yr4-luna.jpgImpacto asteroide 2024 YR4 Luna2025-07-01T14:19:34+00:00monthlyhttps://hoyenelcosmos.com/2025/06/24/primeras-imagenes-del-vera-rubin/https://hoyenelcosmos.com/wp-content/uploads/2025/06/cumulo-galaxias-virgo-vera-rubin-cluster-lowres.jpgThe Cosmic Treasure ChestWelcome to Rubin's cosmic treasure chest! Introducing the first riches from NSF–DOE Vera C. Rubin Observatory’s cosmic treasure chest, a wealth of data that will help scientists make countless new discoveries about our Universe. This image, one of the first released by Rubin Observatory, exposes a Universe teeming with stars and galaxies — transforming seemingly empty, inky-black pockets of space into glittering tapestries for the first time. Only Rubin can quickly produce such large images with this much color and richness. Here, Rubin’s view is focused on the southern region of the Virgo Cluster, about 55 million light-years away from Earth and the nearest large collection of galaxies to our own Milky Way.  What's in this image? The image offers a stunning variety of objects — from bright stars ranging from blue to red in color, to nearby blue spiral galaxies, to distant red galaxy groups — demonstrating the broad range of science made possible by Rubin data. During the 10-year Legacy Survey of Space and Time, scientists around the world will access Rubin’s treasure trove of data to address questions like: How did the Milky Way form? What makes up the 95% of the Universe we can’t see? What will a detailed inventory of Solar System objects reveal? What will we learn from watching hundreds of millions of changes in the night sky over 10 years?  Apart from a few foreground stars in our own Milky Way, the myriad specks of light captured here make up a rich tapestry of about 10 million galaxies— just 0.05%  of the roughly 20 billion galaxies Rubin will image during its 10-year Legacy Survey of Space and Time (LSST). By the end of the survey, Rubin will have revealed this level of detail across the entire southern sky. How was the image created? In addition to showcasing the richness and variety of celestial light in (this area), this deep, 15-square-degree image provides a sample of the way Rubin will observe during the main survey.

Rubin Observatory atop Cerro Pachón in Chile is outlined against the full Moon rising above the horizon. A trick of perspective has enlarged the Moon beyond the size we’d naturally see it on Earth in this Image of the Week. Often regarded as an ‘enemy’ of non-lunar astronomers because of its brightness, the beauty of Earth’s natural satellite cannot be ignored. On the right side of the Moon in this image is the large and relatively young Tycho crater, with its distinctive ray system prominently spreading across the lunar surface. On the bottom and left side are large, dark maria, basaltic plains that formed during the early life of the Moon 1.2–4 billion years ago. The largest of the maria in this image is the Sea of Tranquility, the first site on the Moon visited by humans. This image was captured during the final phase of the construction of Rubin Observatory. Starting in 2025, Rubin will conduct a decade-long survey of the Southern Sky called the Legacy Survey of Space and Time (LSST) and generate about 20 terabytes of data per night.

This remarkable cluster contains hundreds of very massive stars, some shining with a brilliance of almost one million suns. European astronomers have for the first time demonstrated that this magnetar — an unusual type of neutron star with an extremely strong magnetic field — probably was formed as part of a binary star system. The discovery of the magnetar’s former companion elsewhere in the cluster helps solve the mystery of how a star that started off so massive could become a magnetar, rather than collapse into a black hole.https://hoyenelcosmos.com/wp-content/uploads/2025/04/magnetar-pulsar-ilustracion-nasa-sgr.jpgMagnetar Pulsar ilustracion NASA SGR2025-06-14T17:38:06+00:00monthlyhttps://hoyenelcosmos.com/2025/06/10/3-agujeros-negros-devorando-estrellas-masivas/https://hoyenelcosmos.com/wp-content/uploads/2025/06/screenshot_7-6-2025_164133_1.jpegScreenshot_7-6-2025_164133_12025-06-12T00:23:18+00:00monthlyhttps://hoyenelcosmos.com/2025/06/07/misterioso-objeto-que-pulsa-intensamente-en-ondas-de-radio-y-rayos-x/https://hoyenelcosmos.com/wp-content/uploads/2025/06/magnetar-frb-grb-gamma-ray-burst-estallido-lowres.jpgMagnetar FRB GRB gamma ray burst estallido lowreshttps://hoyenelcosmos.com/wp-content/uploads/2025/06/pulsar-askap-j1832-rayos-x-chandra-objeto-enana-blanca-seccion-1-1.jpgPulsar ASKAP J1832 rayos X Chandra objeto enana blanca seccion 1https://hoyenelcosmos.com/wp-content/uploads/2025/06/pulsar-askap-j1832-rayos-x-chandra-objeto-enana-blanca-zoom-lowres.jpgPulsar ASKAP J1832 rayos X Chandra objeto enana blanca zoom lowreshttps://hoyenelcosmos.com/wp-content/uploads/2025/06/pulsar-askap-j1832-rayos-x-chandra-objeto-enana-blanca-seccion-1.jpgPulsar ASKAP J1832 rayos X Chandra objeto enana blanca seccion 12025-06-08T19:28:07+00:00monthlyhttps://hoyenelcosmos.com/2025/06/04/chocaran-realmente-la-via-lactea-y-andromeda/https://hoyenelcosmos.com/wp-content/uploads/2025/06/colision-via-lactea-andromeda-galaxias-choque-fusion-lowres.jpgNGC 520NGC 520https://hoyenelcosmos.com/wp-content/uploads/2025/06/tangled-galaxies-esa-hubble-galaxia-colisionando-chocando-coma-berenice-cumulo-cluster-mcg.jpgTangled galaxiesPreviously the Hubble Picture of the Week series has featured a jewel in the queen’s hair — a spiral galaxy in the constellation Coma Berenices, named for the hair of the historical Egyptian queen. However, that galaxy is only one of many known in this constellation. This week’s new image from the NASA/ESA Hubble Space Telescope depicts the cosmic tangle that is MCG+05-31-045, a pair of interacting galaxies located 390 million light-years away and a part of the so-called Coma galaxy cluster. The Coma cluster is a particularly rich cluster and contains over a thousand known galaxies. Several can be easily seen with amateur telescopes. Most of them are elliptical galaxies, and that’s typical of a dense galaxy cluster like the Coma cluster: many elliptical galaxies are formed in close encounters between galaxies that stir them up, or even collisions that rip them apart. While the stars in the interacting galaxies can stay together, the gas in the galaxies is a different story — it’s twisted and compressed by gravitational forces, and rapidly used up to form new stars. When the hot, massive, blue stars die, there is little gas left to replace them with new generations of young stars. For interacting spiral galaxies, the regular orbits that produce their striking spiral arms are also disrupted. Whether through mergers or simple near misses, the result is a galaxy almost devoid of gas, with ageing stars orbiting in uncoordinated circles: an elliptical galaxy. It’s very likely that a similar fate will befall MCG+05-31-045. As the smaller spiral galaxy is torn up and integrated into the larger galaxy, many new stars will form, and the hot, blue ones will quickly burn out, leaving cooler, redder stars behind in an elliptical galaxy much like the others in the Coma cluster. But this process won’t be complete for many millions of years — until then, Queen Berenice II will have to suffer the knots in her hair!

Informally known as ‘Thor’s Helmet’, NGC 2359 (IC 468) is a giant bubble that is being blown off of the Wolf-Rayet star HD 56925. Wolf-Rayet stars are extremely massive stars that are very hot and luminous. Their intense energy blows off the outer layers, causing the bubble shape seen here. The complex shape of the bubble is due to its interaction with dust and gas in which the star is embedded. The image was generated with observations in Hydrogen alpha (orange), Oxygen [OIII] (blue) and Sulfur [SII] (violet) filters. In this image, North is left, East is down.https://hoyenelcosmos.com/wp-content/uploads/2025/05/potw1608a-wolf-rayet-star-estrella-wr-31-carina-eso-hubble-nebulosa-viento.jpgBlue bubble in CarinaSparkling at the centre of this beautiful NASA/ESA Hubble Space Telescope image is a Wolf–Rayet star known as WR 31a, located about 30 000 light-years away in the constellation of Carina (The Keel). The distinctive blue bubble appearing to encircle WR 31a, and its uncatalogued stellar sidekick, is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical. The bubble — estimated to have formed around 20 000 years ago — is expanding at a rate of around 220 000 kilometres per hour! Unfortunately, the lifecycle of a Wolf–Rayet star is only a few hundred thousand years — the blink of an eye in cosmic terms. Despite beginning life with a mass at least 20 times that of the Sun, Wolf–Rayet stars typically lose half their mass in less than 100 000 years. And WR 31a is no exception to this case. It will, therefore, eventually end its life as a spectacular supernova, and the stellar material expelled from its explosion will later nourish a new generation of stars and planets.https://hoyenelcosmos.com/wp-content/uploads/2025/05/wolf-rayet-140-webb-gas-infrarrojo-concentrico-polvo.jpgWolf Rayet 140 Webb Gas infrarrojo concentrico polvohttps://hoyenelcosmos.com/wp-content/uploads/2025/05/michael-bauer-nebulosa-burbuja-ngc-7635-wolf-rayet-astrobin.jpgMichael Bauer - Nebulosa burbuja ngc 7635 - wolf rayet - astrobinhttps://hoyenelcosmos.com/wp-content/uploads/2025/04/wr-8-wolf-rayet-estrella-puppis-3.jpgWR 8 Wolf Rayet Estrella Puppis 3https://hoyenelcosmos.com/wp-content/uploads/2025/04/wr-8-wolf-rayet-estrella-puppis-2.jpgWR 8 Wolf Rayet Estrella Puppis 2https://hoyenelcosmos.com/wp-content/uploads/2025/04/wr-8-wolf-rayet-estrella-puppis.jpgWR 8 Wolf Rayet Estrella Puppis2025-05-17T20:50:41+00:00monthlyhttps://hoyenelcosmos.com/2025/05/18/los-acantilados-cosmicos-del-webb-3d/https://hoyenelcosmos.com/wp-content/uploads/2025/05/cliff-acantilados-webb-nebulosa-carina-formacion-estelear-gas-interestelar-3.pngCliff acantilados webb nebulosa Carina formacion estelear gas interestelar 3https://hoyenelcosmos.com/wp-content/uploads/2025/05/cliff-acantilados-webb-nebulosa-carina-formacion-estelear-gas-interestelar.pngCliff acantilados webb nebulosa Carina formacion estelear gas interestelarhttps://hoyenelcosmos.com/wp-content/uploads/2025/05/cliff-acantilados-webb-nebulosa-carina-formacion-estelear-gas-interestelar-4.pngCliff acantilados webb nebulosa Carina formacion estelear gas interestelar 4https://hoyenelcosmos.com/wp-content/uploads/2025/05/cliff-acantilados-webb-nebulosa-carina-formacion-estelear-gas-interestelar-2.pngCliff acantilados webb nebulosa Carina formacion estelear gas interestelar 2https://hoyenelcosmos.com/wp-content/uploads/2025/05/cliff-acantilados-ngc-3324-nebula-webb-carina.jpgCliff acantilados NGC 3324 nebula Webb carinahttps://hoyenelcosmos.com/wp-content/uploads/2025/05/webb-eta-carina-nebulosa-riscos-cosmicos-primeras-imagenes.pngWebb eta carina nebulosa riscos cosmicos primeras imagenes2025-05-17T20:28:47+00:00monthlyhttps://hoyenelcosmos.com/2025/05/16/el-universo-caducara-mucho-antes-de-lo-previsto/https://hoyenelcosmos.com/wp-content/uploads/2025/05/evaporation-hawking-radiacion-fin-universo.jpgEvaporation hawking radiacion fin universohttps://hoyenelcosmos.com/wp-content/uploads/2025/05/hawking-radiation-black-hole-agujero-negro.jpgHawking Radiation Black Hole agujero negrohttps://hoyenelcosmos.com/wp-content/uploads/2025/05/hawking-radiation-enana-blanca-dwarf.jpgHawking radiation enana blanca dwarfhttps://hoyenelcosmos.com/wp-content/uploads/2025/05/black-hole-agujero-negro-radiacion-hawking-fin-universo.jpgBlack hole agujero negro radiacion hawking fin universo2025-05-15T15:54:09+00:00monthlyhttps://hoyenelcosmos.com/2025/05/14/el-misterioso-monstruo-verde-de-casiopea-a/https://hoyenelcosmos.com/wp-content/uploads/2025/05/supernova-cas-a-hubble-remanente-cassiopea.jpgSupernova Cas A Hubble remanente CassiopeaSección de Cas A capturada con el Telescopio Espacial Hubble.

The new Hubble image is part of ESA/Hubble’s 35th anniversary celebrations. The cosmic cloud shown here is made of cold hydrogen gas, like the rest of the Eagle Nebula. In such regions of space new stars are born among the collapsing clouds. Hot, energetic and formed in great numbers, the stars unleash an onslaught of ultraviolet light and stellar winds that sculpt the gas clouds around them. This produces fantastical shapes like the narrow pillar with blossoming head that we see here. The material in the pillar is thick and opaque to light; it is highlighted at its edges by the glow of more distant gas behind it. The blue colours of the background are dominated by emission from ionised oxygen; the red colours lower down, glowing hydrogen. Orange colours indicate starlight that has managed to break through the dust: bluer wavelengths are blocked more easily by dust, leaving the redder light to pass through. The stars responsible for carving this particular structure out of the stellar raw material lie just out of view, at the Eagle Nebula’s centre. As the pressure of their intense radiation batters and compresses the gas in this tower of clouds, it’s possible that further star formation is being ignited within. While the starry pillar has withstood these forces well so far, cutting an impressive shape against the background, eventually it will be totally eroded by the multitude of new stars that form in the Eagle Nebula.

While the starry pillar has withstood these forces well so far, cutting an impressive shape against the background, eventually it will be totally eroded by the multitude of new stars that form in the Eagle Nebula.

NGC 5335 is categorized as a flocculent spiral galaxy with patchy streamers of star formation across its disk. There is a striking lack of well-defined spiral arms that are commonly found among galaxies, including our Milky Way. A notable bar structure slices across the center of the galaxy. The bar channels gas inwards toward the galactic center, fueling star formation. Such bars are dynamic in galaxies and may come and go over two-billion-year intervals. They appear in about 30 percent of observed galaxies, including our Milky Way. [Image description: Barred spiral galaxy NGC 5335 observed by the Hubble Space Telescope takes up the majority of the view. At its center is a milky yellow, flattened oval that extends bottom left to top. Within the oval is a bright central region that looks circular, with the very center the brightest. In the bright central region is what looks like a bar, extending from top left to bottom right. Around this is a thick swath of blue stars speckled with white regions. Multiple arms wrap up and around in a counterclockwise direction, becoming fainter the farther out they are. Both the white core and the spiral arms are intertwined with dark streaks of dust. The background of space is black. Thousands of distant galaxies in an array of colors are speckled throughout.]https://hoyenelcosmos.com/wp-content/uploads/2025/04/galaxia-merger-ngc-6240-ofiuco-colision-galactica-hubble-lowres-seccion-1.jpgHubble revisits tangled NGC 6240Not all galaxies are neatly shaped, as this new NASA/ESA Hubble Space Telescope image of NGC 6240 clearly demonstrates. Hubble previously released an image of this galaxy back in 2008, but the knotted region, shown here in a pinky-red hue at the centre of the galaxies, was only revealed in these observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. NGC 6240 lies 400 million light-years away in the constellation of Ophiuchus (The Serpent Holder). This galaxy has an elongated shape with branching wisps, loops and tails. This mess of gas, dust and stars bears more than a passing resemblance to a butterfly and, though perhaps less conventionally beautiful, a lobster. This bizarrely-shaped galaxy did not begin its life looking like this; its distorted appearance is a result of a galactic merger that occurred when two galaxies drifted too close to one another. This merger sparked bursts of new star formation and triggered many hot young stars to explode as supernovae. A new supernova was discovered in this galaxy in 2013, named SN 2013dc. It is not visible in this image, but its location is indicated here. At the centre of NGC 6240 an even more interesting phenomenon is taking place. When the two galaxies came together, their central black holes did so too. There are two supermassive black holes within this jumble, spiralling closer and closer to one another. They are currently only some 3000 light-years apart, incredibly close given that the galaxy itself spans 300 000 light-years. This proximity secures their fate as they are now too close to escape each other and will soon form a single immense black hole. Links Images of Hubblehttps://hoyenelcosmos.com/wp-content/uploads/2025/04/nebulosa-planetaria-kohoutek-4-55-cisne-hubble-seccion-1-1.jpgSwan song for stars and camerasThe swirling, paint-like clouds in the darkness of space in this stunning image seem surreal, like a portal to another world opening up before us. In fact, the subject of this ESA/Hubble Picture of the Week is very real. We are seeing vast clouds of ionised atoms and molecules, thrown into space by a dying star. This is a planetary nebula named Kohoutek 4-55, a member of the Milky Way galaxy situated just 4600 light-years away in the constellation Cygnus (the Swan). Planetary nebulae are the spectacular final display at the end of a giant star’s life. Once a red giant star has exhausted its available fuel and shed its last layers of gas, its compact core will contract further, enabling a final burst of nuclear fusion. The exposed core reaches extremely hot temperatures, radiating very energetic ultraviolet light that energises the enormous clouds of cast-off gas. Molecules in the gas are ionised and glow brightly; here, red and orange indicate nitrogen molecules, green is hydrogen and blue shows oxygen in the nebula. Kohoutek 4-55 has an uncommon, multi-layered form: a bright inner ring is surrounded by a fainter layer of gas, all wrapped in a broad halo of ionised nitrogen. The spectacle is bittersweet, as the brief phase of fusion in the core will end after mere tens of thousands of years, leaving a white dwarf that will never illuminate the clouds around it again. This image itself is also a swan song, the final work of one of Hubble’s instruments: the Wide Field and Planetary Camera 2 (WFPC2). Installed in 1993 to replace the original Wide Field and Planetary Camera, WFPC2 was responsible for some of Hubble’s most enduring images and fascinating discoveries. It in turn was replaced by the Wide Field Camera 3 in 2009, during Hubble’s final servicing mission. The data for this image were taken a mere ten days before the instrument was removed from the telescope, as a fitting send-off for WFPC2 after 16 years’ work.

Taken in visible light, the image shows the tip of the three-light-year-long pillar, bathed in the glow of light from hot, massive stars off the top of the image. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure. Hubble's Wide Field Camera 3 observed the Carina Nebula on 24-30 July 2009. WFC3 was installed aboard Hubble in May 2009 during Servicing Mission 4. The composite image was made from filters that isolate emission from iron, magnesium, oxygen, hydrogen and sulphur. These Hubble observations of the Carina Nebula are part of the Hubble Servicing Mission 4 Early Release Observations.2025-04-27T18:46:56+00:00monthlyhttps://hoyenelcosmos.com/2025/04/30/descubierta-la-galaxia-espiral-mas-antigua-del-universo/https://hoyenelcosmos.com/wp-content/uploads/2025/04/galaxia-espiral-zhulong-antorcha-dragon-panoramic-noirlab-webb-lowres.jpgGalaxia espiral Zhulong antorcha dragon panoramic NOIRLab Webb lowreshttps://hoyenelcosmos.com/wp-content/uploads/2025/04/ngc6946-galaxia_espiral_formacion-estelar-webb-supernovas.pngNGC6946-Galaxia_espiral_formacion-estelar-Webb-Supernovashttps://hoyenelcosmos.com/wp-content/uploads/2025/04/galaxia-espiral-zhulong-antorcha-dragon-panoramic-noirlab-webb.jpgGalaxia espiral Zhulong antorcha dragon panoramic NOIRLab Webb2025-04-27T17:54:55+00:00monthlyhttps://hoyenelcosmos.com/2025/04/24/hubble-cumple-35-anos-un-legado-cosmico-y-cuatro-nuevas-vistas-espectaculares/https://hoyenelcosmos.com/wp-content/uploads/2025/04/marte-hubble-aniversario.jpgMars (December 2024)This is a combination of Hubble Space Telescope images of Mars taken from December 28th to 30th, 2024. At the midpoint of the observations, Mars was approximately 98 million kilometres from Earth. Thin water-ice clouds that are apparent in ultraviolet light give the Red Planet a frosty appearance. The icy northern polar cap was experiencing the start of Martian spring.  In the left image, the bright orange Tharsis plateau is visible with its chain of dormant volcanoes. The largest volcano, Olympus Mons, pokes above the clouds at the 10 o’clock position near the northwest limb. At an elevation of 21 000 metres, it is 2.5 times the height of Mt. Everest above sea level. Valles Marineris, Mars’ roughly 4,000 kilometre-long canyon system, is a dark, linear, horizontal feature near center left.  In the right image, high-altitude evening clouds can be seen along the planet’s eastern limb. The 2,250-kilometre-wide Hellas basin, an ancient asteroid impact feature, appears far to the south. Most of the hemisphere is dominated by the classical “shark fin” feature, Syrtis Major. [Image description: Two views of planet Mars on a black background of space observed by the Hubble Space Telescope. At left, text: December 28, 2024 20:00 UT. At right, text: December 29, 2024 13:18 UT. In both images, its atmosphere is clear and the surface appears detailed. Most of the planet is shades of orange. At left, the brightest orange area appears in the left half. At right, the brightest orange area is centered and takes on the rough shape of a sleeping mask. In both views, darker surface features are noticeable on the lower half of the planet. These have a mix of orange, blue, and gray hues. At the top and bottom, white regions mark the planet’s polar caps. The entire limb of the planet, its visible edge, has a blue hue. The blue doesn’t form an even circle at the edges, and appears thinner toward the left and right, and thicker in some areas.]https://hoyenelcosmos.com/wp-content/uploads/2025/04/ngc-5335-galaxia-hubble-barrada-lowres.jpgBarred Spiral Galaxy NGC 5335The Hubble Space Telescope captured in exquisite detail a face-on view of a remarkable-looking galaxy. NGC 5335 is categorized as a flocculent spiral galaxy with patchy streamers of star formation across its disk. There is a striking lack of well-defined spiral arms that are commonly found among galaxies, including our Milky Way. A notable bar structure slices across the center of the galaxy. The bar channels gas inwards toward the galactic center, fueling star formation. Such bars are dynamic in galaxies and may come and go over two-billion-year intervals. They appear in about 30 percent of observed galaxies, including our Milky Way. [Image description: Barred spiral galaxy NGC 5335 observed by the Hubble Space Telescope takes up the majority of the view. At its center is a milky yellow, flattened oval that extends bottom left to top. Within the oval is a bright central region that looks circular, with the very center the brightest. In the bright central region is what looks like a bar, extending from top left to bottom right. Around this is a thick swath of blue stars speckled with white regions. Multiple arms wrap up and around in a counterclockwise direction, becoming fainter the farther out they are. Both the white core and the spiral arms are intertwined with dark streaks of dust. The background of space is black. Thousands of distant galaxies in an array of colors are speckled throughout.]https://hoyenelcosmos.com/wp-content/uploads/2025/04/nebulosa-roseta-region-formacion-estelar-monoceros-hubble-seccion-1.jpgRosette NebulaThis is a Hubble Space Telescope photo of a small portion of the Rosette Nebula, a huge star-forming region spanning 100 light-years across and located 5,200 light-years away. Hubble zooms into a small portion of the nebula that is only 4 light-years across (the approximate distance between our Sun and the neighbouring Alpha Centauri star system.) Dark clouds of hydrogen gas laced with dust are silhouetted across the image. The clouds are being eroded and shaped by the seething radiation from the cluster of larger stars in the center of the nebula (NGC 2440). An embedded star seen at the tip of a dark cloud in the upper right portion of the image is launching jets of plasma that are crashing into the cold cloud around it. The resulting shock wave is causing a red glow. The colours come from the presence of hydrogen, oxygen, and nitrogen. [Image description: A tiny portion of the Rosette Nebula. Very dark gray material shaped like a V extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right, and looser on the piece that goes toward the top right. Behind the dark gray on the left side, from the bottom left to top center, there is dust that looks like arced claw marks that appears in light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, most toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.]https://hoyenelcosmos.com/wp-content/uploads/2025/04/nebulosa-roseta-region-formacion-estelar-monoceros-hubble-lowres.jpgRosette Nebula context imageThe Rosette Nebula is a vast star-forming region, 100 light-years across, that lies at one end of a giant molecular cloud the constellation Monoceros. The nebula is estimated to contain around 10,000 solar masses. The nebula is located about 5,000 light-years away from Earth. Intense radiation from the young stars inside a cluster in the nebula causes the gasses to glow. The background image is from the Digitized Sky Survey, while the inset is a small portion of the nebula as photographed by the Hubble Space Telescope. Dark clouds of hydrogen gas laced with dust are silhouetted across the image. The colours come from the presence of hydrogen, oxygen, and nitrogen. [Image description: A square, ground-based observation of the entire Rosette Nebula. A large, diffuse donut shape primarily composed of light brown and gray gas and dust extends to the edges.

This object has a diagonal, bipolar, cylindrical outflow of gas. This is propelled by radiation and stellar winds from a nearly 22 000 degree Celsius white dwarf at the center. In fact, there may be two companion stars that are interacting and sculpting the nebula, which is pinched in the middle by a fragmented ring or torus – looking like a half-eaten donut. It has a forest of gaseous “pillars” that point back to the source of radiation and stellar winds. The colours are from glowing hydrogen and oxygen. The nebula lies approximately 4,500 light-years away in the southern constellation Vela. [Image description: The planetary nebula NGC 2899 is shaped like a single macaroni noodle, with its edges pointed up, but its edge-on central torus is semi-transparent in the middle. The top and bottom edges are thick and orange. The center is semi-transparent blue and green. The wider central region looks roughly like a moth, also filled with semi-transparent blue and green. There are two pinpoint-like white stars with diffraction spikes toward the center. Immediately below them, slightly toward the right, is a smaller blue orb, a central star. The next layer of gas and dust is whiter, with some thicker pillars that look like they are rising up at bottom center.

In fact, the subject of this ESA/Hubble Picture of the Week is very real. We are seeing vast clouds of ionised atoms and molecules, thrown into space by a dying star. This is a planetary nebula named Kohoutek 4-55, a member of the Milky Way galaxy situated just 4600 light-years away in the constellation Cygnus (the Swan). Planetary nebulae are the spectacular final display at the end of a giant star’s life. Once a red giant star has exhausted its available fuel and shed its last layers of gas, its compact core will contract further, enabling a final burst of nuclear fusion. The exposed core reaches extremely hot temperatures, radiating very energetic ultraviolet light that energises the enormous clouds of cast-off gas. Molecules in the gas are ionised and glow brightly; here, red and orange indicate nitrogen molecules, green is hydrogen and blue shows oxygen in the nebula. Kohoutek 4-55 has an uncommon, multi-layered form: a bright inner ring is surrounded by a fainter layer of gas, all wrapped in a broad halo of ionised nitrogen. The spectacle is bittersweet, as the brief phase of fusion in the core will end after mere tens of thousands of years, leaving a white dwarf that will never illuminate the clouds around it again. This image itself is also a swan song, the final work of one of Hubble’s instruments: the Wide Field and Planetary Camera 2 (WFPC2). Installed in 1993 to replace the original Wide Field and Planetary Camera, WFPC2 was responsible for some of Hubble’s most enduring images and fascinating discoveries. It in turn was replaced by the Wide Field Camera 3 in 2009, during Hubble’s final servicing mission. The data for this image were taken a mere ten days before the instrument was removed from the telescope, as a fitting send-off for WFPC2 after 16 years’ work.

NGC 3603 is located in the Carina spiral arm of the Milky Way galaxy at a distance of about 20,000 light-years (6-7 kpc). It is the only massive, galactic "HII-region" (so denoted by astronomers because part of its hydrogen is ionized) in which a central cluster of strongly UV-radiating stars of types O and B that ionize the nebula can be studied at visual and near-infrared wavelengths. This is because the line-of-sight is reasonably free of dust in this direction; the dimming in near-infrared radiation due to intervening matter between the nebula and us is only about a factor of 2 (compared to 80 in visible light). The total mass of the hot O and B stars in NGC 3603 is over 2,000 solar masses. Together, the more than fifty heavy and bright O stars in NGC 3603 have about 100 times the ionizing power of the well-known Trapezium cluster in the Orion Nebula. In fact, the star cluster in NGC 3603 is in many respects very similar to the core of the large, ionizing cluster in the approximately eight times more distant Tarantula Nebula in the Large Magellanic Cloud. An important conclusion of studying this region is that there are lots of sub-solar mass stars in NGC 3603. Contrary to several theoretical predictions, these low-mass stars do form in violent starbursts. The overall age of stars in the contraction phase that are located in the innermost region of NGC 3603 was found to be 300 000 to 1 000 000 years. The counts clearly show that this cluster is well populated in sub-solar mass stars. This image is available as a mounted image in the ESOshop.https://hoyenelcosmos.com/wp-content/uploads/2024/04/ngc_3603_ngc3603_nebulosa_cumulo_estelar_carina_hubble.jpgStarburst cluster shows celestial fireworksLike a 4th of July fireworks display, a young, glittering collection of stars looks like an aerial burst. The cluster is surrounded by clouds of interstellar gas and dust—the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603. This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the gas and dust enveloping the cluster, providing an unobstructed view of the cluster. Most of the stars in the cluster were born around the same time but differ in size, mass, temperature, and colour. The course of a star's life is determined by its mass, so a cluster of a given age will contain stars in various stages of their lives, giving an opportunity for detailed analyses of stellar life cycles. NGC 3603 also contains some of the most massive stars known. These huge stars live fast and die young, burning through their hydrogen fuel quickly and ultimately ending their lives in supernova explosions. Star clusters like NGC 3603 provide important clues to understanding the origin of massive star formation in the early, distant Universe. Astronomers also use massive clusters to study distant starbursts that occur when galaxies collide, igniting a flurry of star formation. The proximity of NGC 3603 makes it an excellent lab for studying such distant and momentous events. This Hubble Space Telescope image was captured in August 2009 and December 2009 with the Wide Field Camera 3 in both visible and infrared light, which trace the glow of sulfur, hydrogen, and iron.2025-04-21T18:33:36+00:00monthlyhttps://hoyenelcosmos.com/2025/04/15/webb-captura-imagenes-directas-de-exoplanetas-gigantes-y-detecta-dioxido-de-carbono/https://hoyenelcosmos.com/wp-content/uploads/2025/04/exoplanet-imaging-hr-8799e-eso-calzada.jpgexoplanet imaging HR 8799e ESO CalzadaThe GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry.

The blue and yellow lines are a best-fit model for an atmosphere that would be either low or high in metals heavier than helium, including carbon, also known as metallicity. The Webb data is consistent with a high metallicity planet. Spectral fingerprints of carbon dioxide and carbon monoxide appear in data collected by Webb’s NIRCam (Near-Infrared Camera).

Its distance is equivalent to a location between the orbits of Neptune and Saturn in our solar system. The observations detected the planet is rich in carbon dioxide, providing strong evidence that the planet formed much like Jupiter and Saturn, by slowly building a solid core that attracted gas from within a protoplanetary disk. The 51 Eridani system is 96 light-years from Earth. This image includes filters representing 4.1-micron light as red. [Image description: This image shows the exoplanet 51 Eri b.

The observations detected carbon dioxide in each of the planets, which provides strong evidence that the system’s four giant planets formed much like Jupiter and Saturn, by slowly building solid cores that attract gas from within a protoplanetary disk. Colours are applied to filters from Webb’s NIRCam (Near-Infrared Camera), revealing their intrinsic differences. A star symbol marks the location of the host star HR 8799, whose light has been blocked by a coronagraph. The colours in this image, which represent different wavelengths captured by Webb’s NIRCam, tell researchers about the temperatures and composition of the planets. HR 8799 b, which orbits around 10.1 billion kilometres from the star, is the coldest of the bunch, and the richest in carbon dioxide. HR 8799 e orbits 2.4 billion kilometres from its star, and likely formed closer to the host star, where there were stronger variations in the composition of material. In this image, the colour blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to the 4.6 micron light. [Image description: This image shows the planetary system HR 8799.

This is the first close-up picture of a star outside our own galaxy, the Milky Way. The star is located in the Large Magellanic Cloud, over 160 000 light-years away. The bright oval at the centre of this image is a dusty cocoon that enshrouds the star. A fainter elliptical ring around it could be the inner rim of a dusty torus, but more observations are needed to confirm this feature. 2024-11-22T01:14:29+00:00monthlyhttps://hoyenelcosmos.com/2024/11/05/detectan-un-supermasivo-y-su-festin-de-materia/https://hoyenelcosmos.com/wp-content/uploads/2024/11/artists_impression_of_a_black_hole_and_accretion_disk_black-hole-5k-agujero-negro.jpgArtist's_impression_of_a_black_hole_and_accretion_disk_(Black-Hole-5K) agujero negroSupermassive black holes are found at the center of galaxies, chomping on gas and dust that gets pulled into their strong gravitational field.

This image is from the SPHERE/ZIMPOL observations of R Aquarii, and shows the binary star itself, as well as the jets of material spewing from the stellar couple.https://hoyenelcosmos.com/wp-content/uploads/2024/10/potw1850a-r-aquarii-eso-vlt.jpgVLT view of binary system R Aquarii from 2012This image reveals a dramatic binary star system named R Aquarii, located 700 light-years from Earth, as seen in 2012 by ESO’s Very Large Telescope (VLT). R Aquarii is a so-called “symbiotic binary”, comprising two stars surrounded by a large, dynamic cloud of gas (a nebula). Systems like this contain two stars in an unequal and complex relationship. R Aquarii is made up of one hot white dwarf and one red giant. The red giant is losing matter to its small companion and occasionally ejecting matter in weird spurts, loops and trails, forming the intriguing shapes seen here. There is a lot going on between the performers in this cosmic double act. The red giant is a variable star, with a brightness that changes by a factor of 750 every year and three weeks. The faint nebula is named Cederblad 211 and is thought to be the result of a violent nova 250 years ago. Also visible is a narrow, vertical, S-shaped feature, with blobs of superheated material moving outward at tremendous speeds of 600 to 850 kilometres per second. R Aquarii was also imaged 15 years ago — and several times in the intervening period — to track its ongoing activity. The system is very dynamic and complex, and has expanded and evolved significantly in recent years (an image from 1997 can be seen here, and a comparison between the two is available here).https://hoyenelcosmos.com/wp-content/uploads/2024/10/archives_raquarii-hubble-r-aquarii-symbiotic-doble-binaria.webparchives_raquarii hubble r aquarii symbiotic doble binariahttps://hoyenelcosmos.com/wp-content/uploads/2024/10/heic2413a-r-aquarii-hubble-estrella-simbiotica-doble-binaria-enana-blanca-gigante-roja.jpgR AquariiThis image features R Aquarii, a symbiotic binary star that lies only roughly 1,000 light-years from Earth in the constellation Aquarius.

Named RCW 7, the nebula is located just over 5300 light-years from Earth in the constellation Puppis. Nebulae are areas of space that are rich in the raw material needed to form new stars. Under the influence of gravity, parts of these molecular clouds collapse until they coalesce into protostars, surrounded by spinning discs of leftover gas and dust. In the case of RCW 7, the protostars forming here are particularly massive, giving off strongly ionising radiation and fierce stellar winds that have transformed it into what is known as a H II region. H II regions are filled with hydrogen ions — where H I refers to a normal hydrogen atom, H II is hydrogen that has lost its electron. The ultraviolet radiation from the massive protostars excites the hydrogen, causing it to emit light and giving this nebula its soft pinkish glow. Here Hubble is studying a particular massive protostellar binary named IRAS 07299-1651, still in its glowing cocoon of gas in the curling clouds towards the top of the nebula. To expose this star and its siblings, this image was captured using the Wide Field Camera 3 in near-infrared light. The massive protostars here are brightest in ultraviolet light, but they emit plenty of infrared light which can pass through much of the gas and dust around them and be seen by Hubble. Many of the other, larger-looking stars in this image are not part of the nebula, but sit between it and our Solar System. The creation of an H II region marks the beginning of the end for a molecular cloud. Over only a few million years, the radiation and winds from the massive stars gradually disperse the gas — even more so as the most massive stars come to the end of their lives in supernova explosions.

Only a fraction of the gas will be incorporated into new stars in this nebula, with the rest being spread throughout the galaxy to eventually form new mole2024-10-19T03:00:48+00:00monthlyhttps://hoyenelcosmos.com/2024/10/18/como-llegaron-los-componentes-basicos-de-la-vida-a-la-tierra/https://hoyenelcosmos.com/wp-content/uploads/2024/10/cinturon-asteroides-belt_0.jpgCinturon-Asteroides-belt_0https://hoyenelcosmos.com/wp-content/uploads/2024/10/013122_lk_asteriod_feat_asteroide_troyano_planetesimal.jpg013122_lk_asteriod_feat_Asteroide_Troyano_Planetesimal2024-10-18T04:14:52+00:00monthlyhttps://hoyenelcosmos.com/2024/10/17/buscan-senales-de-radio-en-el-sistema-estelar-trappist-1/https://hoyenelcosmos.com/wp-content/uploads/2024/10/exoplaneta_the_trappist-1_habitable_zone.jpgExoplaneta_The_TRAPPIST-1_Habitable_Zonehttps://hoyenelcosmos.com/wp-content/uploads/2024/10/c-csiro-parkes-telescope-parkes-night_radio-telescopio-radiotelescopio.jpgc-csiro-parkes-telescope-parkes-night_Radio-telescopio-radiotelescopiohttps://hoyenelcosmos.com/wp-content/uploads/2024/10/greenabank-ta_radiotelescopio_gbt_telescopio-1.jpggreenabank-TA_Radiotelescopio_GBT_telescopiohttps://hoyenelcosmos.com/wp-content/uploads/2024/10/radiotelescopio_inaf_italia_sadinia_antena_telescopio.jpgRadiotelescopio_INAF_italia_Sadinia_antena_telescopiohttps://hoyenelcosmos.com/wp-content/uploads/2024/10/greenabank-ta_radiotelescopio_gbt_telescopio.jpggreenabank-TA_Radiotelescopio_GBT_telescopiohttps://hoyenelcosmos.com/wp-content/uploads/2024/10/allen-radio-telescope-antenas-arreglo-array.jpgAllen-radio-telescope-antenas-arreglo-arrayhttps://hoyenelcosmos.com/wp-content/uploads/2024/10/image_5697_2e-trappist-1_exoplaneta.jpgimage_5697_2e-TRAPPIST-1_Exoplaneta2024-10-17T03:21:00+00:00monthlyhttps://hoyenelcosmos.com/2024/10/16/la-primera-pagina-en-el-atlas-cosmico-de-euclid/https://hoyenelcosmos.com/wp-content/uploads/2024/10/euclid-mosaico-mapa-entrega-esa-nasa-telescopio-oscura-materia-energia-otras-galaxias.jpgEuclid mosaico mapa entrega ESA NASA Telescopio oscura materia energia otras galaxiashttps://hoyenelcosmos.com/wp-content/uploads/2024/10/euclid-mosaico-mapa-entrega-esa-nasa-telescopio-oscura-materia-energia-galaxias-espirales-2-abell-3381.jpgEuclid mosaico mapa entrega ESA NASA Telescopio oscura materia energia galaxias espirales 2 Abell 3381https://hoyenelcosmos.com/wp-content/uploads/2024/10/euclid-mosaico-mapa-entrega-esa-nasa-telescopio-oscura-materia-energia-galaxias-region.jpgEuclid mosaico mapa entrega ESA NASA Telescopio oscura materia energia galaxias regionhttps://hoyenelcosmos.com/wp-content/uploads/2024/10/euclid-mosaico-mapa-entrega-esa-nasa-telescopio-oscura-materia-energia-galaxias-2-abell-3381.jpgEuclid mosaico mapa entrega ESA NASA Telescopio oscura materia energia galaxias 2 Abell 3381https://hoyenelcosmos.com/wp-content/uploads/2024/10/euclid-mosaico-mapa-entrega-esa-nasa-telescopio-oscura-materia-energia-galaxias.jpgEuclid mosaico mapa entrega ESA NASA Telescopio oscura materia energia galaxias2024-10-16T22:36:58+00:00monthlyhttps://hoyenelcosmos.com/the-astrophysical-journal-letters/2024-07-29T19:15:55+00:00weekly0.6https://hoyenelcosmos.com/2024/07/23/un-cumulo-galactico-rodeado-por-gas-a-millones-de-grados-celsius/https://hoyenelcosmos.com/wp-content/uploads/2024/07/heic0814d-hubble-abell-2390-cumulo-galaxias-seccion-central.jpgAbell 2390Located 2.7 billion light-years from the Earth (redshift 0.23), Abell 2390 is located in the constellation Pegasus. The large arcs seen around the central cluster are distortions of other objects located behind Abell 2390, the light from which is bent and magnified as it passes by the galaxy cluster. When a massive galaxy cluster acts as a lens, like in these new Hubble images, arcs and arclets of light are formed. The images come in different sizes and shapes depending on how distant they are from us and each other and how close the source light passes by the galaxy cluster itself. The extent to which the image is distorted and the number of copies of the background object created depend on the alignment between the galaxy cluster and the distant body.https://hoyenelcosmos.com/wp-content/uploads/2024/07/pegaso-sky-map-abell-2390-1.jpgPegasushttps://hoyenelcosmos.com/wp-content/uploads/2024/07/peg-pegasus-pegaso-iau-mapa-constelacion.jpgPegasushttps://hoyenelcosmos.com/wp-content/uploads/2024/07/pegaso-sky-map-abell-2390.jpgPegasushttps://hoyenelcosmos.com/wp-content/uploads/2024/07/euclid-image-galaxy-cluster-abell-2390-cumulo.jpg{"shape": [8200, 8200, 3]}{"shape": [8200, 8200, 3]}https://hoyenelcosmos.com/wp-content/uploads/2024/07/xmm-newton-gas-abell-2390-rayos-x.jpg{"shape": [8200, 8200, 3]}{"shape": [8200, 8200, 3]}2024-07-23T04:41:54+00:00monthlyhttps://hoyenelcosmos.com/2024/07/11/hubble-encuentra-evidencia-de-un-agujero-negro-de-masa-intermedia-en-omega-centauri/https://hoyenelcosmos.com/wp-content/uploads/2024/07/stsci-01evt5kekx6xqk96336jtwf6za-hubble-omega-centauri-globular-cluster-cumulo.jpgSTScI-01EVT5KEKX6XQK96336JTWF6ZA Hubble Omega Centauri Globular Cluster Cumulohttps://hoyenelcosmos.com/wp-content/uploads/2024/07/image-1.pngimagehttps://hoyenelcosmos.com/wp-content/uploads/2024/07/stsci-01j1x1rzvdzs3hv0s5vbhc7x0r-centro-omega-centauri-cumulo-globular.pngSTScI-01J1X1RZVDZS3HV0S5VBHC7X0R Centro Omega Centauri cumulo globularhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/gaia_black_holes_pillars-bh2-bh3-agujero-negro-esa-gaia.jpgGaia_Black_Holes_pillars BH2 BH3 agujero negro ESA GAIAhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/eso2406b-m87-sagitario-eht-agujero-supermasivo-polarizacion_lowres.jpgM87* and Sgr A* side-by-side in polarised lightSeen here in polarised light, this side-by-side image of the supermassive black holes M87* and Sagittarius A* indicates to scientists that these beasts have similar magnetic field structures. This is significant because it suggests that the physical processes that govern how a black hole feeds and launches a jet may be universal features amongst supermassive black holes. The scale shows the apparent size on the sky of these images, in units of micro-arcseconds. A finger held at arm's length measures 1 degree on the sky; a micro-arcsecond is 3.6 billion times smaller than that. In context, the images of these black holes have an apparent size similar to that of a donut on the surface of the Moon.https://hoyenelcosmos.com/wp-content/uploads/2024/07/stsci-01j1x1w2vgfqv5b9vtha2ra2y6-omega-cen-hubble-cumulo-globular-agujero-negro-intermedio.pngSTScI-01J1X1W2VGFQV5B9VTHA2RA2Y6 Omega Cen Hubble Cumulo globular agujero negro intermedio2024-07-11T20:47:21+00:00monthlyhttps://hoyenelcosmos.com/2024/06/22/la-constante-de-hubble-origenes-y-evolucion-del-universo/https://hoyenelcosmos.com/wp-content/uploads/2024/06/image-1.pngimagehttps://hoyenelcosmos.com/wp-content/uploads/2024/06/cefeidas-hubble-weeb-expancion.jpgComparison of Hubble and Webb views of a Cepheid variable starAt the centre of these side-by-side images is a special class of star used as a milepost marker for measuring the Universe’s rate of expansion — a Cepheid variable star. The two images are very pixelated because each is a very zoomed-in view of a distant galaxy. Each of the pixels represents one or more stars. The image from the James Webb Space Telescope is significantly sharper at near-infrared wavelengths than Hubble (which is primarily a visible-ultraviolet light telescope). By reducing the clutter with Webb’s crisper vision, the Cepheid stands out more clearly, eliminating any potential confusion. Webb was used to look at a sample of Cepheids and confirmed the accuracy of the previous Hubble observations that are fundamental to precisely measuring the Universe’s expansion rate and age. [Image description: A horizontal two-panel image of pixelated, black-and-white star fields. The left image is labelled Webb Near-IR and has a few dozen points of light of varying brightness. At the centre of the image, one bright point is circled. The right image is labelled Hubble Near-IR and has more indistinct, blurry patches whose overall brightness is similar to the more defined regions in the left image. At the centre, a light grey pixel is circled.]https://hoyenelcosmos.com/wp-content/uploads/2024/06/spt-benson-2020-winter-cosmic-microwave-background-observatorio-antena-microondas-polo-sur-antartida.jpgspt-benson-2020-winter cosmic microwave background observatorio antena microondas polo sur antartidahttps://hoyenelcosmos.com/wp-content/uploads/2024/06/hs-article-darkenergy-2400x1200_energia-oscura_cosmologia.jpghs-article-darkEnergy-2400x1200_energia-oscura_cosmologiahttps://hoyenelcosmos.com/wp-content/uploads/2024/06/expandinguniverse.jpgexpandingUniversehttps://hoyenelcosmos.com/wp-content/uploads/2024/06/infografia_webb_cosmologico_redshift_expasion_galaxias_infrarrojo.pnginfografia_Webb_cosmologico_redshift_expasion_galaxias_infrarrojohttps://hoyenelcosmos.com/wp-content/uploads/2024/06/einstein-hubble.jpgeinstein-Hubble2025-06-17T17:07:27+00:00monthlyhttps://hoyenelcosmos.com/2024/07/08/cinco-galaxias-en-llamas/https://hoyenelcosmos.com/wp-content/uploads/2024/07/image.pngimagehttps://hoyenelcosmos.com/wp-content/uploads/2021/07/galaxias_alma.jpggalaxias_ALMA2024-07-08T19:09:11+00:00monthlyhttps://hoyenelcosmos.com/2024/03/22/pons-brooks-el-cometa-del-ano/https://hoyenelcosmos.com/wp-content/uploads/2024/03/012p_2024-03-05_light-cometa-pons-brooks-pepe-chambo.jpg012p_2024-03-05_light-cometa-pons-brooks-pepe-chambohttps://hoyenelcosmos.com/wp-content/uploads/2024/03/cometa-pons-brook-vallestad_2564.jpgcometa-pons-brook-vallestad_2564https://hoyenelcosmos.com/wp-content/uploads/2024/03/e1df3eef-f0ef-4248-a0bd-b247a768cede-pons-brooks-cometa.pnge1df3eef-f0ef-4248-a0bd-b247a768cede-pons-brooks-cometahttps://hoyenelcosmos.com/wp-content/uploads/2024/03/7mrrwvfqehs2gycgebckyl-pons-brooks-cometa-jan-erik-vallestard.jpg7MRRWVFqEHS2GyCGeBCKyL Pons Brooks Cometa Jan Erik Vallestard2024-07-08T18:49:23+00:00monthlyhttps://hoyenelcosmos.com/2024/07/06/cinco-objetos-para-disfrutar-el-cielo-de-julio/https://hoyenelcosmos.com/wp-content/uploads/2024/07/portada-cinco-objetos-julio.jpgPortada cinco objetos juliohttps://hoyenelcosmos.com/wp-content/uploads/2024/07/hercules_iau.jpgHercules_IAUhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/m13_tvdavis_cumulo_globular.jpgm13_tvdavis_Cumulo_globularhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/768px-heart_of_m13_hercules_globular_cluster.jpg768px-Heart_of_M13_Hercules_Globular_Clusterhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/scorpius_iau-2-1.jpgScorpius_IAU-2https://hoyenelcosmos.com/wp-content/uploads/2024/07/region_central_via_lactea_01-messier-6-7-cumulo-ptolomeo-mariposa-m6-m7-escorpion-1.jpgRegion_Central_Via_Lactea_01 Messier 6 7 Cumulo Ptolomeo Mariposa M6 M7 escorpionhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/messier-6-butterfly-cluster-mariposa-cumulo-escorpion-m6.jpgMessier 6 Butterfly Cluster Mariposa cumulo escorpion M6https://hoyenelcosmos.com/wp-content/uploads/2024/07/scorpius_iau-2.jpgScorpius_IAU-2https://hoyenelcosmos.com/wp-content/uploads/2024/07/region_central_via_lactea_01-messier-6-7-cumulo-ptolomeo-mariposa-m6-m7-escorpion.jpgRegion_Central_Via_Lactea_01 Messier 6 7 Cumulo Ptolomeo Mariposa M6 M7 escorpionhttps://hoyenelcosmos.com/wp-content/uploads/2024/07/2227px-star-cluster-messier-7-ptolomeo-cumulo-estelar-escorpion.jpg2227px star cluster Messier 7 Ptolomeo cumulo estelar EscorpionThis new image from the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile, shows the bright star cluster Messier 7, also known as NGC 6475.

The young objects are surrounded by softly illuminated gas and dust of this stellar nursery. The system is only about 2.8 million years old, very young for a star system. Our Sun, by contrast, is about 4.6 billion years old. FS Tau B is a newly forming star, or protostar, and is surrounded by a protoplanetary disc, a pancake-shaped collection of dust and gas leftover from the formation of the star that will eventually coalesce into planets. The thick dust lane, seen nearly edge-on, separates what are thought to be the illuminated surfaces of the disc. FS Tau B is likely in the process of becoming a T Tauri star, a type of young variable star that hasn’t begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun. Protostars shine with the heat energy released as the gas clouds from which they are forming collapse, and from the accretion of material from nearby gas and dust. Variable stars are a class of star whose brightness changes noticeably over time. FS Tau A is itself a T Tauri binary system, consisting of two stars orbiting each other. Protostars are known to eject fast-moving, column-like streams of energised material called jets, and FS Tau B provides a striking example of this phenomenon. The protostar is the source of an unusual asymmetric, double-sided jet, visible here in blue. Its asymmetrical structure may be because mass is being expelled from the object at different rates. FS Tau B is also classified as a Herbig-Haro object. Herbig–Haro objects form when jets of ionised gas ejected by a young star collide with nearby clouds of gas and dust at high speeds, creating bright patches of nebulosity.

The young objects are surrounded by softly illuminated gas and dust of this stellar nursery. The system is only about 2.8 million years old, very young for a star system. Our Sun, by contrast, is about 4.6 billion years old. FS Tau B is a newly forming star, or protostar, and is surrounded by a protoplanetary disc, a pancake-shaped collection of dust and gas leftover from the formation of the star that will eventually coalesce into planets. The thick dust lane, seen nearly edge-on, separates what are thought to be the illuminated surfaces of the disc. FS Tau B is likely in the process of becoming a T Tauri star, a type of young variable star that hasn’t begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

It's composed of a series of images taken during a total solar eclipse visible from ESO's La Silla Observatory on 2 July 2019. Baily's Beads are caused by the Moon's mountains, valleys, and craters. These surface features create an uneven edge of the Moon, where small "beads" of sunlight still shine through the lowest parts for a few moments after the rest of the Sun is covered. In this picture, multiple images taken in quick succession show that the beads disappear and appear in stages, with only the very deepest valley and craters allowing the sunlight to shine through closest to totality. The phenomenon is named after Francis Baily, a British astronomer whose observations in the early 1800s first widely publicised their existence. Appropriately, 2019 was the 245th anniversary of Baily's birth.https://hoyenelcosmos.com/wp-content/uploads/2024/03/74_annular_eclipse-16x9-1.jpg74_annular_eclipse-16x9-1https://hoyenelcosmos.com/wp-content/uploads/2024/03/annular_eclipse_h.jpgannular_eclipse_hhttps://hoyenelcosmos.com/wp-content/uploads/2024/03/01eclipse.jpg01eclipsehttps://hoyenelcosmos.com/wp-content/uploads/2024/03/in-annular_eclipse.jpgin-annular_eclipsehttps://hoyenelcosmos.com/wp-content/uploads/2024/03/eclipse_personas_solar_sol_astronomos.jpgeclipse_personas_solar_sol_astronomoshttps://hoyenelcosmos.com/wp-content/uploads/2024/03/eclipse-de-sol.jpgeclipse-de-solhttps://hoyenelcosmos.com/wp-content/uploads/2024/03/eclipse-de-sol-1_corona-solar_iac.jpgeclipse de sol-1_Corona-solar_IAC2024-03-17T21:30:54+00:00monthlyhttps://hoyenelcosmos.com/2024/03/11/la-ciencia-de-oppenheimer-conoce-a-los-asesores-de-la-pelicula-ganadora-del-oscar/https://hoyenelcosmos.com/wp-content/uploads/2024/03/oppenheimer-2023_pelicula-4.jpgoppenheimer-2023_pelicula-4https://hoyenelcosmos.com/wp-content/uploads/2024/03/oppenheimer-2023_pelicula-3.jpgoppenheimer-2023_pelicula-3https://hoyenelcosmos.com/wp-content/uploads/2024/03/oppenheimer-einstein-pelicula.jpgoppenheimer-einstein-peliculahttps://hoyenelcosmos.com/wp-content/uploads/2024/03/oppenheimer-pelicula-bomba-trinity.jpgOPPENHEIMEROPPENHEIMERhttps://hoyenelcosmos.com/wp-content/uploads/2024/03/film-oppenheimer-pelicula.jpgfilm-oppenheimer-peliculahttps://hoyenelcosmos.com/wp-content/uploads/2024/03/robbert-dijkgraaf-1.jpgrobbert-dijkgraaf-1Robbert Dijkgraaf, minister van Onderwijs, Cultuur en Wetenschap.

This region is a hotbed of star formation and home to more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives. In the MIRI view of NGC 604, there are noticeably fewer stars than Webb’s NIRCam image. This is because hot stars emit much less light at these wavelengths. Some of the stars seen in this image are red supergiants — stars that are cool but very large, hundreds of times the diameter of our Sun. The blue tendrils of material signify the presence of polycyclic aromatic hydrocarbons, or PAHs. [Image description: At the centre of the image is a nebula on the black background of space. The nebula is composed of wispy filaments of light blue clouds. At the centre-right of the blue clouds is a large cavernous bubble. The bottom left edge of this cavernous bubble is filled with hues of pink and white gas. Hundreds of dim stars fill the area surrounding the nebula.]https://hoyenelcosmos.com/wp-content/uploads/2024/03/weic2407a-nebulosa-ngc-604-formacion-estelar-galaxia-triangulo-webb-nircam.jpgNGC 604 (NIRCam image)This image from the NASA/ESA/CSA James Webb Space Telescope’s NIRCam (Near-Infrared Camera) of star-forming region NGC 604 shows how stellar winds from bright, hot young stars carve out cavities in surrounding gas and dust. The bright orange streaks in this image signify the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons, or PAHs. As you travel further from the immediate cavities of dust where the star is forming, the deeper red signifies molecular hydrogen. This cooler gas is a prime environment for star formation. Ionised hydrogen from ultraviolet radiation appears as a white and blue ghostly glow. NGC 604 is located in the Triangulum Galaxy (M33), 2.73 million light-years away from Earth. It provides an opportunity for astronomers to study a high concentration of very young, massive stars in a nearby region. [Image description: At the centre of the image is a nebula on the black background of space. The nebula is composed of clumpy, red, filamentary clouds. At the centre-right of the red clouds is a large cavernous bubble, and at the centre of the bubble there is an opaque blue glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula.

The LMC lies about 157 000 light-years from Earth, and is a so-called satellite galaxy of the Milky Way, meaning that the two galaxies are gravitationally bound. Globular clusters are very stable, tightly bound clusters of thousands or even millions of stars. Their stability means that they can last a long time, and therefore globular clusters are often studied in order to investigate potentially very old stellar populations.  In fact, 2017 research that made use of some of the data that were also used to build this image revealed that a sample of LMC globular clusters were incredibly close in age to some of the oldest stellar clusters found in the Milky Way’s halo. They found that NGC 2210 specifically probably clocks in at around 11.6 billion years of age. Even though this is only a couple of billion years younger than the Universe itself, it made NGC 2210 by far the youngest globular cluster in their sample. All other LMC globular clusters studied in the same work were found to be even older, with four of them over 13 billion years old. This is interesting, because it tells astronomers that the oldest globular clusters in the LMC formed contemporaneously with the oldest clusters in the Milky Way, even though the two galaxies formed independently.  As well as being a source of interesting research, this old-but-relatively-young cluster is also extremely beautiful, with its highly concentrated population of stars. The night sky would look very different from the perspective of an inhabitant of a planet orbiting one of the stars in a globular cluster’s centre: the sky would appear to be stuffed full of stars, in a stellar environment that is thousands of times more crowded than our own.

These dwarf galaxies, which orbit the galactic centre, are only visible from the Southern Hemisphere. Here, they are seen above the Auxiliary Telescopes of ESO's Very Large Telescope (VLT) in Paranal, Chile.https://hoyenelcosmos.com/wp-content/uploads/2023/12/noirlab2106a_ngc474_ctio_noirlab_galaxia.jpgElliptical galaxy NGC 474 — excerpt from the Dark Energy SurveElliptical galaxies are generally characterized by their relatively smooth appearance when compared with spiral galaxies (one of which is to the left), which have more flocculent structures interwoven with dust lanes and spiral arms. NGC 474 is at a distance of about 100 million light-years in the constellation of Pisces. This image shows unusual structures around NGC 474 characterized as tidal tails and shell-like structures made up of hundreds of millions of stars. These features are due to recent mergers (within the last billion years) or close interactions with smaller infalling dwarf galaxies.  This image is an excerpt from the Dark Energy Survey, which has released a massive, public collection of astronomical data and calibrated images from six years of work. The Dark Energy Survey is a global collaboration that includes the Department of Energy's (DOE) Fermi National Accelerator Laboratory (Fermilab), the National Center for Supercomputing Applications (NCSA), and NSF’s NOIRLab. The image was taken with the Dark Energy Camera, fabricated by DOE, on the Víctor M. Blanco 4-meter Telescope. The quality of the survey can be appreciated by diving into the zoomable version of this wider excerpt showing a background tapestry of thousands of distant galaxies. https://hoyenelcosmos.com/wp-content/uploads/2023/12/ii-zw-96-galaxias-colision-webb.jpgGalactic Get-TogetherA merging galaxy pair cavort in this image captured by the NASA/ESA/CSA James Webb Space Telescope. This pair of galaxies, known to astronomers as II ZW 96, is roughly 500 million light-years from Earth and lies in the constellation Delphinus, close to the celestial equator. As well as the wild swirl of the merging galaxies, a menagerie of background galaxies are dotted throughout the image.The two galaxies are in the process of merging and as a result have a chaotic, disturbed shape. The bright cores of the two galaxies are connected by bright tendrils of star-forming regions, and the spiral arms of the lower galaxy have been twisted out of shape by the gravitational perturbation of the galaxy merger. It is these star-forming regions that made II ZW 96 such a tempting target for Webb; the galaxy pair is particularly bright at infrared wavelengths thanks to the presence of the star formation. This observation is from a collection of Webb measurements delving into the details of galactic evolution, in particular in nearby Luminous Infrared Galaxies such as II ZW 96. These galaxies, as the name suggests, are particularly bright at infrared wavelengths, with luminosities more than 100 billion times that of the Sun. An international team of astronomers proposed a study of complex galactic ecosystems — including the merging galaxies in II ZW 96 — to put Webb through its paces soon after the telescope was commissioned. Their chosen targets have already been observed with ground-based telescopes and the NASA/ESA Hubble Space Telescope, which will provide astronomers with insights into Webb’s ability to unravel the details of complex galactic environments. Webb captured this merging galaxy pair with a pair of its cutting-edge instruments; NIRCam — the Near-InfraRed Camera — and MIRI, the Mid-InfraRed Instrument. If you are interested in exploring the differences between Hubble and Webb’s observations of II ZW 96, you can do so here.MIRI was contributed by ESA anhttps://hoyenelcosmos.com/wp-content/uploads/2023/12/messier-61-galaxia-espiral-brotes_hubble.jpgSpiral SnapshotThe luminous heart of the galaxy M61 dominates this image, framed by its winding spiral arms threaded with dark tendrils of dust. As well as the usual bright bands of stars, the spiral arms of M61 are studded with ruby-red patches of light. Tell-tale signs of recent star formation, these glowing regions lead to M61’s classification as a starburst galaxy. Though the gleaming spiral of this galaxy makes for a spectacular sight, one of the most interesting features of M61 lurks unseen at the centre of this image. As well as widespread pockets of star formation, M61 hosts a supermassive black hole more than 5 million times as massive as the Sun. M61 appears almost face-on, making it a popular subject for astronomical images, even though the galaxy lies more than 52 million light-years from Earth. This particular astronomical image incorporates data from not only Hubble, but also the FORS camera at the European Southern Observatory’s Very Large Telescope, together revealing M61 in unprecedented detail. This striking image is one of many examples of telescope teamwork — astronomers frequently combine data from ground-based and space-based telescopes to learn more about the Universe.https://hoyenelcosmos.com/wp-content/uploads/2023/12/messier-51-whirpool_galaxia_espiral_hubble.jpgThe Heart of the Whirlpool GalaxyThe Whirlpool galaxy, M51, has been one of the most photogenic galaxies in amateur and professional astronomy. Easily photographed and viewed by smaller telescopes, this celestial beauty is studied extensively in a range of wavelengths by large ground- and space-based observatories. This Hubble composite image shows visible starlight as well as light from the emission of glowing hydrogen, which is associated with the most luminous young stars in the spiral arms.https://hoyenelcosmos.com/wp-content/uploads/2023/12/heic2313b_ugc-8091_enana_galaxia_dwarf_hubble.jpgDwarf irregular galaxy UGC 8091 (wide-field view)For the end of the year and the holiday season Hubble has captured the festive bundle of lights known as UGC 8091. UGC 8091, also known as GR 8, lies around seven million light-years from Earth in the constellation Virgo. It is a dwarf irregular galaxy: a comparatively small, low-mass galaxy without a distinct or uniform shape. The filters used in this image date from 2006 up to 2021, and were taken by two of Hubble’s most advanced instruments: the Wide Field Camera 3 and the Advanced Camera for Surveys. An astonishing twelve filters combine to produce this image, with light from the mid-ultraviolet right through to the red end of the visible spectrum contributing. The blossoming patches of red represent light emitted by excited hydrogen molecules in hot, energetic stars that have formed in recent starbursts. The other glittering lights on show are a mix of older stars. [Image description: A collection of stars and galaxies fill the scene against a dark background. The image is dominated by a dense collection of stars that make up the irregular galaxy UGC 8091. The stars span a variety of colours, including blue and orange, with patches of blue occupying the central part of the galaxy. There are also visible circular regions of red/pink gas within the galaxy.]2023-12-21T20:54:20+00:00monthlyhttps://hoyenelcosmos.com/2023/12/09/betelgeuse-podria-desaparecer-este-12-de-diciembre/https://hoyenelcosmos.com/wp-content/uploads/2023/12/orionspringdickinson1024_bill-dickinson.jpgOrionSpringDickinson1024_Bill-Dickinsonhttps://hoyenelcosmos.com/wp-content/uploads/2023/12/betelgeuse-feb-2016-and-dec-31-2019-brian-otturn-earthsky.jpgBetelgeuse-Feb-2016-and-Dec-31-2019-Brian-Otturn-EarthSkyhttps://hoyenelcosmos.com/wp-content/uploads/2023/12/occultation-path-1-leona-betelgeuse-2023.jpgoccultation-path-1-leona-betelgeuse-20232023-12-21T20:36:49+00:00monthlyhttps://hoyenelcosmos.com/2017/08/31/nova-astrologos-coreanos/https://hoyenelcosmos.com/wp-content/uploads/2017/08/149092_web_nova_enana.jpg149092_web_nova_enanaSerie de imágenes tomadas en 1942 donde se puede ver el cambio en el brillo de la nova enana (Shara et al. 2017)https://hoyenelcosmos.com/wp-content/uploads/2017/08/scanof1000000.jpgscanof1000000Ramy Imam y Lindsay Smith son parte del proyecto DASCH.

WASP-39 b is a hot, puffy gas giant planet with a mass 0.28 times that of Jupiter (0.94 times that of Saturn) and a diameter 1.3 times that of Jupiter, orbiting just 0.0486 astronomical units (4 520 000 miles) from its host star. The star, WASP-39, is fractionally smaller and less massive than the Sun. Because it is so close to its star, WASP-39 b is very hot and is likely to be tidally locked, meaning that one side faces the star at all times. Data collected by Webb’s Near-Infrared Spectrograph (NIRSpec) show unambiguous evidence for carbon dioxide in the atmosphere, while previous observations from Hubble, Spitzer, and other telescopes indicate the presence of water vapour, sodium, and potassium, as well. The planet probably has clouds and some form of weather, but may not have atmospheric bands like those of Jupiter and Saturn. This illustration is based on indirect transit observations from Webb as well as other space and ground-based telescopes. Webb has not captured a direct image of this planet.NIRSpec was built for the European Space Agency (ESA) by a consortium of European companies led by Airbus Defence and Space (ADS) with NASA’s Goddard Space Flight Centre providing its detector and micro-shutter subsystems.2023-12-21T19:40:32+00:00monthlyhttps://hoyenelcosmos.com/2023/01/01/lineas-de-hielo-para-enormes-mundos-ardientes/2023-12-21T19:39:46+00:00monthlyhttps://hoyenelcosmos.com/2023/01/21/dos-agujeros-negros-supermasivos-en-una-galaxia-fusionada/https://hoyenelcosmos.com/wp-content/uploads/2023/01/treister_sciart_v3_ugc4211_agn.giftreister_sciart_v3_ugc4211_agnhttps://hoyenelcosmos.com/wp-content/uploads/2023/01/nrao-004-galaxy_bh_merger2h_ugc4211_agn.jpegNRAO-004-galaxy_bh_mergerALMA Scientists Find Pair of Black Holes Dining Together in Nearby Galaxy Merger While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)— and international observatory co-operated by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO)— scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What’s more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.https://hoyenelcosmos.com/wp-content/uploads/2023/01/gc4211_nrao_agn.pngGC4211_NRAO_AGN2023-12-21T19:38:16+00:00monthlyhttps://hoyenelcosmos.com/2023/04/14/gaia-descubre-los-agujeros-negros-mas-cercanos/https://hoyenelcosmos.com/wp-content/uploads/2023/04/mpia-closestbh_el-badry_2022_overview_d_agujero_negro_gaia_bh1-bh2.pngmpia-closestbh_el-badry_2022_overview_d_agujero_negro_Gaia_BH1-BH22023-12-21T19:36:30+00:00monthlyhttps://hoyenelcosmos.com/2023/04/22/un-caotico-y-bello-final/https://hoyenelcosmos.com/wp-content/uploads/2023/04/ring_nebula_webb_anillo_nebulosa_planetaria_miri.pngRing_Nebula_Webb_anillo_nebulosa_planetaria_MIRI2023-12-21T19:30:11+00:00monthlyhttps://hoyenelcosmos.com/2023/04/27/amenazados-por-supernovas/2023-12-21T19:29:29+00:00monthlyhttps://hoyenelcosmos.com/2023/04/29/las-galaxias-mas-lejanas-del-webb/2023-12-21T19:28:14+00:00monthlyhttps://hoyenelcosmos.com/2023/05/04/el-telescopio-james-webb-revela-los-ladrillos-de-la-formacion-planetaria/https://hoyenelcosmos.com/wp-content/uploads/2023/05/ngc346_webb_nebulosa_smc_medres-376508248-e1683154373541.jpgNGC346_Webb_Nebulosa_SMC_medres2023-12-21T19:27:26+00:00monthlyhttps://hoyenelcosmos.com/2023/05/14/mercurio-venus-y-la-tierra-hasta-cuando-permaneceran-en-sus-orbitas/https://hoyenelcosmos.com/wp-content/uploads/2023/05/671506main_pia15628_full-sistema-solar-asteroides-orbitas-planetas-nasa.jpg671506main_PIA15628_full-sistema-solar-asteroides-orbitas-planetas-nasa2023-12-21T19:25:22+00:00monthlyhttps://hoyenelcosmos.com/2023/08/03/en-busca-de-las-particulas-de-materia-oscura/https://hoyenelcosmos.com/wp-content/uploads/2023/08/xenon_press_release1_materia_oscura_wimps.jpgxenon_press_release1_materia_oscura_wimpshttps://hoyenelcosmos.com/wp-content/uploads/2023/08/lux-zeplin-dark-matter-materia-oscura-wimps_2.jpglux-zeplin-dark-matter-materia-oscura-wimps_2https://hoyenelcosmos.com/wp-content/uploads/2023/08/lux-zeplin_dark-matter-wimp-materia-oscura.jpglux-zeplin_dark-matter-wimp-materia-oscurahttps://hoyenelcosmos.com/wp-content/uploads/2023/08/dark-matter-sub-atomic-particle-artists-concept-particulas-materia-oscura.jpgDark-Matter-Sub-Atomic-Particle-Artists-Concept-Particulas-Materia-Oscura2023-12-21T19:14:34+00:00monthlyhttps://hoyenelcosmos.com/2013/08/30/la-luna-de-bonafonte/https://hoyenelcosmos.com/wp-content/uploads/2013/08/e26e0-victorian_man_flying.jpge26e0-victorian_man_flying2023-12-21T19:10:09+00:00monthlyhttps://hoyenelcosmos.com/2014/01/17/divulgacion-de-la-ciencia-y-cultura/https://hoyenelcosmos.com/wp-content/uploads/2014/01/cosmic-distances_fl.jpgcosmic-distances_FL2023-12-21T18:57:11+00:00monthlyhttps://hoyenelcosmos.com/2012/05/31/el-hombre-de-venus-primera-parte/https://hoyenelcosmos.com/wp-content/uploads/2012/05/viaje_siberia_chappe_documento_portada.jpgEl hombre de Venus.

Despite its fragmented, rubbly nature, the total mass contained within the belt is considerable — roughly four per cent of that of the Moon! The majority of this mass is contained within two distinctive bodies: Ceres, a dwarf planet estimated to make up a third of the mass of the belt, and the asteroid Vesta, which holds around nine per cent of it. Vesta is pictured here. Vesta was recently observed by the SPHERE/ZIMPOL instrument on ESO’s Very Large Telescope (VLT) — the SPHERE image is shown on the left (see the single image here), produced using the MISTRAL algorithm, with a synthetic view derived from space-based data shown on the right for comparison. SPHERE, the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, is a powerful planet-finding and direct imaging instrument. ZIMPOL is one of its subsystems: a specialised camera perfectly suited to taking very sharp images of small objects — like Vesta. The synthetic image was generated using a tool developed for space missions called OASIS. Factors such as the reflectance of Vesta’s surface and the geometric conditions of the VLT/SPHERE observations where accounted for by OASIS, which used a 3D model of Vesta’s shape based on images from NASA’s Dawn spacecraft (which completed a 14-month survey of Vesta between 2011 and 2012). SPHERE’s image of Vesta is impressive given the separation between Earth and Vesta, and the small size of the asteroid — it lies twice as far from the Sun as our planet does, and has a mean diameter of just 525 kilometres. It shows Vesta’s main features: the giant impact basin at Vesta's south pole, and the mountain at the bottom right. This is the central peak of the Rheasilvia basin, and is roughly 22 kilometres high — over twice as high as the tallest mountain on Earth, Mauna Kea, which rises roughly 10 kilometres from the basin of the Pacifichttps://hoyenelcosmos.com/wp-content/uploads/2023/12/claudia_crater_vesta_iotd-298_dawn_define_meridiano.jpgclaudia_crater_vesta_iotd-298_dawn_define_meridianohttps://hoyenelcosmos.com/wp-content/uploads/2023/12/fresco_of_vesta-hestia_from_pompeii.jpgfresco_of_vesta-hestia_from_pompeiihttps://hoyenelcosmos.com/wp-content/uploads/2023/12/ceres_and_vesta_moon_size_comparison_luna_tamanio_comparacion.jpgceres_and_vesta_moon_size_comparison_luna_tamanio_comparacionhttps://hoyenelcosmos.com/wp-content/uploads/2023/12/cc_dec23_vesta_900_asteroide_mapa_2024.jpgcc_dec23_vesta_900_asteroide_mapa_20242023-12-21T16:46:40+00:00monthlyhttps://hoyenelcosmos.com/2023/11/23/las-joyas-del-heroe-una-mirada-al-cielo-de-perseo/https://hoyenelcosmos.com/wp-content/uploads/2023/11/1080px-the_2010_perseids_over_the_vlt.jpg1080px-the_2010_perseids_over_the_vlthttps://hoyenelcosmos.com/wp-content/uploads/2023/11/ngc1499californianebula1024.jpgngc1499californianebula1024https://hoyenelcosmos.com/wp-content/uploads/2023/11/ngc1023_jeffjohnson_galaxia.jpgngc1023_jeffjohnson_galaxiahttps://hoyenelcosmos.com/wp-content/uploads/2023/11/ngc_1260-galaxia-lenticular.pngngc_1260-galaxia-lenticularhttps://hoyenelcosmos.com/wp-content/uploads/2023/11/1080px-euclids_view_of_the_perseus_cluster_of_galaxies_cumulo-galaxias.jpg{"shape": [8800, 8800, 3]}{"shape": [8800, 8800, 3]}https://hoyenelcosmos.com/wp-content/uploads/2023/11/little_dumbbell_nebula_m76_by_goran_nilsson_wim_van_berlo__liverpool_telescope_planetaria_messier-76.jpglittle_dumbbell_nebula_m76_by_goran_nilsson_wim_van_berlo__liverpool_telescope_planetaria_messier-76https://hoyenelcosmos.com/wp-content/uploads/2023/11/m34_mazur_cumulo_estelar_estrellas.jpgm34_mazur_cumulo_estelar_estrellashttps://hoyenelcosmos.com/wp-content/uploads/2023/11/21111-algol-perseo_ilustracion.jpgArtwork of Algol Triple StarAn impression of the system Algol (Beta Persei).

At first glance, Webb’s NIRCam image appears less colourful than the MIRI image. But this is only because the material from the object is emitting light at many different wavelengths The NIRCam image appears a bit sharper than the MIRI image because of its greater resolution. The outskirts of the main inner shell, which appeared as a deep orange and red in the MIRI image, look like smoke from a campfire in the NIRCam image. This marks where the supernova blast wave is ramming into surrounding circumstellar material. The dust in the circumstellar material is too cool to be detected directly at near-infrared wavelengths, but lights up in the mid-infrared. Also not seen in the near-infrared view is the loop of green light in the central cavity of Cas A that glowed in mid-infrared light, nicknamed the Green Monster by the research team. The circular holes visible in the MIRI image within the Green Monster, however, are faintly outlined in white and purple emission in the NIRCam image. [Image description: A comparison between two images, one on the left (labelled NIRCam), and on the right (labelled MIRI), separated by a white line. On the left, the image is of a roughly circular cloud of gas and dust with a complex structure. The inner shell is made of bright pink and orange filaments that look like tiny pieces of shattered glass. Around the exterior of the inner shell are curtains of wispy gas that look like campfire smoke. On the right is the same nebula seen in different light. The curtains of material outside the inner shell glow orange instead of white. The inner shell looks more mottled, and is a muted pink. At centre right, a greenish loop extends from the right side of the ring into the central cavity.]  https://hoyenelcosmos.com/wp-content/uploads/2023/12/weic2330a_cassiopeia-a-webb-supernova_nircam.jpgCas A (NIRCam image)A new high-definition image from the NASA/ESA/CSA James Webb Space Telescope’s NIRCam (Near-Infrared Camera) unveils intricate details of supernova remnant Cassiopeia A (Cas A), and shows the expanding shell of material slamming into the gas shed by the star before it exploded. The most noticeable colours in Webb’s newest image are clumps of bright orange and light pink that make up the inner shell of the supernova remnant. These tiny knots of gas, composed of sulphur, oxygen, argon, and neon from the star itself, are only detectable thanks to NIRCam’s exquisite resolution, and give researchers a hint at how the dying star shattered like glass when it exploded. The outskirts of the main inner shell look like smoke from a campfire. This marks where ejected material from the exploded star is ramming into surrounding circumstellar material. Researchers have concluded that this white colour is light from synchrotron radiation, which is generated by charged particles travelling at extremely high speeds and spiralling around magnetic field lines. There are also several light echoes visible in this image, most notably in the bottom right corner. This is where light from the star’s long-ago explosion has reached, and is warming, distant dust, which glows as it cools down.

The inner shell is made of bright pink and orange filaments studded with clumps and knots that look like tiny pieces of shattered glass. Around the exterior of the inner shell, there are curtains of wispy gas that look like campfire smoke. Around and within the nebula, various stars are seen as points of blue and white light. Outside the nebula, there are also clumps of dust, coloured yellow in the image.]https://hoyenelcosmos.com/wp-content/uploads/2023/12/cassiopeia_a_miri_jwst_webb_supernova_explosion.pngCassiopeia_A_MIRI_JWST_Webb_Supernova_explosion2023-12-14T21:54:54+00:00monthlyhttps://hoyenelcosmos.com/2023/11/30/seis-planetas-resonantes/https://hoyenelcosmos.com/wp-content/uploads/2023/11/02_20231129_medienmitteilung_unibe_unige_cheops_tess_sextett_planeten_walzerc2a9nccr_planets_thibautroger.jpgThe waltz of the HD110067 planets sextuplet forming a resonanceTracing a link between two neighbour planet at regular time interval along their orbits, create a pattern unique to each couple.

The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disc, the makings of future planetary systems. The young stars at the centre of many of these discs are similar in mass to the Sun or smaller. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The lighter-coloured gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space. [Image description: Red dual opposing jets coming from young stars fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom centre, tilted toward two o’clock, with a bright star at its centre. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the centre, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. The image’s largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges.

The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star. The image was obtained by NOIRLab’s Communication, Education & Engagement team as part of the NOIRLab Legacy Imaging Program.2023-07-14T03:15:09+00:00monthlyhttps://hoyenelcosmos.com/2023/07/07/una-mancha-solar-tan-grande-que-se-ve-desde-marte/https://hoyenelcosmos.com/wp-content/uploads/2023/07/nasa-perseverence-rover-mars-press.jpgnasa-perseverence-rover-mars-presshttps://hoyenelcosmos.com/wp-content/uploads/2023/07/marsspots_perseverance_marte_rover.jpgmarsspots_perseverance_marte_roverhttps://hoyenelcosmos.com/wp-content/uploads/2023/07/mars_perseverance_zl7_0844_0741880936_428eby_n0410000zcam01064_1100lmj_sun.pngmars_perseverance_zl7_0844_0741880936_428eby_n0410000zcam01064_1100lmj_sunhttps://hoyenelcosmos.com/wp-content/uploads/2023/07/screenshot-559.pngscreenshot-559https://hoyenelcosmos.com/wp-content/uploads/2023/07/tosi-philippe-2023-07-06-1205-phtosi-l204mm-cpntinuum-coul_1688646143_sol_mancha_solar.jpgtosi-philippe-2023-07-06-1205-phtosi-l204mm-cpntinuum-coul_1688646143_sol_mancha_solar2023-07-07T13:57:44+00:00monthlyhttps://hoyenelcosmos.com/2023/07/02/euclid-va-en-busca-del-universo-oscuro/https://hoyenelcosmos.com/wp-content/uploads/2023/07/fm_integration_euclides_euclid_esa_telescopio.jpgfm_integration_euclides_euclid_esa_telescopiohttps://hoyenelcosmos.com/wp-content/uploads/2023/07/41554_a4-1600px_euclides_esa_telescopio.jpgThermal & Structural modelEUCLIDhttps://hoyenelcosmos.com/wp-content/uploads/2023/07/euclid_lift-off_lanzamiento_euclides_euclid_telescopio_2.jpgEuclid_lift-off_lanzamiento_Euclides_Euclid_Telescopio_22023-07-01T20:17:12+00:00monthlyhttps://hoyenelcosmos.com/2023/07/01/rafagas-de-radio-podrian-anunciar-ondas-gravitacionales/https://hoyenelcosmos.com/wp-content/uploads/2023/06/e88_1_estrellas_neutrones_pulsares_coalesencias.pnge88_1_estrellas_neutrones_pulsares_coalesenciashttps://hoyenelcosmos.com/wp-content/uploads/2023/06/55890703neutron-star-collison-animation.jpg55890703neutron-star-collison-animationhttps://hoyenelcosmos.com/wp-content/uploads/2023/06/ska_radio_antenas.jpgska_radio_antenasComposite image of the SKA telescopes, blending real hardware already on site with artist's impressions.

New stars are born in the colourful clouds of gas and dust seen here. The infrared observations underlying this image reveal new details in the star-forming regions that are usually obscured by the clouds of dust. The image was produced with data collected by the VIRCAM instrument, which is attached to the VISTA telescope at ESO’s Paranal Observatory in Chile. The observations were done as part of the VISIONS survey, which will allow astronomers to better understand how stars form in these dust-enshrouded regions.https://hoyenelcosmos.com/wp-content/uploads/2023/05/vista_lupus_lupus-3_visions_vircam_nebulosa_eso_meingastparanal_medres.jpgThe Lupus 3 region in visible lightA dark cloud of cosmic dust snakes across this spectacular image, illuminated by the brilliant light of new stars. This dense cloud is a star-forming region called Lupus 3, where dazzlingly hot stars are born from collapsing masses of gas and dust. This image was created from images taken using the VLT Survey Telescope and the MPG/ESO 2.2-metre telescope.

The observations were obtained with telescopes from the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA), of which ESO is a partner, and the Greenland Telescope. This image gives scientists the context needed to understand how the powerful jet is formed. The new observations also revealed that the black hole’s ring, shown here in the inset, is 50% larger than the ring observed at shorter radio wavelengths by the Event Horizon Telescope (EHT). This suggests that in the new image we see more of the material that is falling towards the black hole than what we could see with the EHT. https://hoyenelcosmos.com/wp-content/uploads/2023/04/nrao21df04_m87_total_intensity_magrot_112021.jpegnrao21df04_M87_Total_Intensity_MagRot_112021Galaxia Messier 87 vista por los radiotelescopios VLA.

The site shown here is Cerro Paranal, home to ESO's Very Large Telescope (VLT), a telescope comprising four 8.2-metre Unit Telescopes. The VLT can also act as an interferometer in the form of the appropriately-named VLT Interferometer, or VLTI, by gathering additional light from four smaller Auxiliary Telescopes, which can be independently moved around and placed in different configurations. One of these Auxiliary Telescopes is shown in this image, gazing at the sky with its dome wide open. The road from the observatory to the Residencia appears as a shining thread, weaving amongst the rocky outcrops and hills of the desert environment. The yellow glow is caused by dim security lights — the street lighting is kept to a minimum in order to avoid unnecessary light pollution. ESO/B.

The planet is believed to be rocky and to have a mass about a quarter that of Earth. Two other planets known to orbit Proxima Centauri are visible in the image too: Proxima b, a planet with about the same mass as Earth that orbits the star every 11 days and is within the habitable zone, and candidate Proxima c, which is on a longer five-year orbit around the star.2022-02-20T02:49:55+00:00monthlyhttps://hoyenelcosmos.com/2021/07/14/primeras-mediciones-de-isotopos-en-la-atmosfera-de-un-exoplaneta/2022-02-13T05:41:48+00:00monthlyhttps://hoyenelcosmos.com/2021/06/18/el-podcast-de-narices-de-tycho-galaxias-medusa-jacopo-fritz/https://hoyenelcosmos.com/wp-content/uploads/2021/06/723px-nasas_hubble_finds_life_is_too.jpg723px-NASA's_Hubble_Finds_Life_is_Toohttps://hoyenelcosmos.com/wp-content/uploads/2021/06/imagen-galaxias-medusa.jpgImagen-Galaxias-Medusa2022-02-12T22:09:38+00:00monthlyhttps://hoyenelcosmos.com/2021/06/21/el-podcast-de-narices-de-tycho-el-enigma-de-betelgeuse-joel-sanchez/https://hoyenelcosmos.com/wp-content/uploads/2021/06/eso2003b.jpgSPHERE’s view of Betelgeuse in January 2019The red supergiant star Betelgeuse, in the constellation of Orion, has been undergoing unprecedented dimming. This stunning image of the star’s surface was taken with the SPHERE instrument on ESO’s Very Large Telescope in January 2019, before the star started to dim.

First identified in 1958 by radio telescopes, it makes a rich cosmic tapestry in this image from NASA's recently retired Spitzer Space Telescope. Located about 17,000 light-years from Earth, in the direction of the constellation Aquila in the night sky, W51 is about 350 light-years - or about 2 quadrillion miles - across. It is almost invisible to telescopes that collect visible light (the kind human eyes detect), because that light is blocked by interstellar dust clouds that lie between W51 and Earth. But longer wavelengths of light, including radio and infrared, can pass unencumbered through the dust. When viewed in infrared by Spitzer, W51 is a spectacular sight: Its total infrared emission is the equivalent of 20 million Suns.2021-03-29T16:56:25+00:00monthlyhttps://hoyenelcosmos.com/2018/07/02/dawn-revela-panoramas-unicos-en-ceres/https://hoyenelcosmos.com/wp-content/uploads/2018/07/dawn_ceres_crater_lines.pngDawn_ceres_crater_linesDepósitos salinos y de carbonatos en la superficie de Ceres.https://hoyenelcosmos.com/wp-content/uploads/2018/07/dawn_ceres_crater.jpgDawn_ceres_craterhttps://hoyenelcosmos.com/wp-content/uploads/2018/07/pia21248_hires_ceres_dawn_crater.jpgPIA21248_hires_Ceres_Dawn_Craterhttps://hoyenelcosmos.com/wp-content/uploads/2018/07/480px-color_global_view_of_ceres_-_oxo_and_haulani_craters.png480px-Color_global_view_of_Ceres_-_Oxo_and_Haulani_cratersPlaneta enano Ceres.2021-02-04T03:03:20+00:00monthlyhttps://hoyenelcosmos.com/2018/07/05/einstein-verificado-una-estrella-de-neutrones-ultradensa-cae-igual-que-una-pluma/https://hoyenelcosmos.com/wp-content/uploads/2018/07/pulsar_00.gifPulsar_00Los pulsares son como faros: si el haz de radiación queda en dirección de la Tierra, podemos detectarlos con su destello regular.https://hoyenelcosmos.com/wp-content/uploads/2018/07/042617_ec_quantum-equivalence_main_free.jpg042617_EC_quantum-equivalence_main_FREEEn la teoría de relatividad de Einstein la masa de los objetos deforma el espacio-tiempo. https://hoyenelcosmos.com/wp-content/uploads/2018/07/pulsar-in-a-stellar-triple-system.jpgPulsar-in-a-Stellar-Triple-SystemIlustración artística del sistema triple de objetos.https://hoyenelcosmos.com/wp-content/uploads/2018/07/nrao18cb11_arrtistimpress-1170x600.jpgnrao18cb11_arrtistimpress-1170x6002021-02-04T03:02:59+00:00monthlyhttps://hoyenelcosmos.com/2018/07/08/quasar-da-pistas-del-universo-temprano/https://hoyenelcosmos.com/wp-content/uploads/2018/07/nrao18df3_quasar-e1531069897670.jpgRadio-Loud Quasar at z~6Imagen con las antenas del VLBA, del quasar QSO P352-15.https://hoyenelcosmos.com/wp-content/uploads/2018/07/slide_1_vlba_telescopes-e1531069813302.jpgslide_1_VLBA_telescopesUbicación de las antenas del VLBA.

Engineers at ESO have recently completed the difficult process of aligning the grating. The production and alignment of this component is one of the key ESO contributions to the ESPRESSO project. The grating is the largest ever assembled at ESO, and its length matches the largest echelle grating ever made — the 1.2 x 0.3 metre grating for the HIRES spectrograph at the Keck 10-metre telescope. After its final alignment, the grating is fixed in a permanent mount. All its components are made of Zerodur (the same material that is used for the mirrors of the VLT) and will require no further adjustments, ever. This mounting technique was pioneered at ESO, and demonstrated to work on earlier instruments. When installed at ESO’s Paranal Observatory in Chile in 2016, ESPRESSO will combine the light from all four Unit Telescopes of the Very Large Telescope to create a virtual 16-metre aperture telescope. Its diffraction grating will split up the light into its component colours for analysis — spreading the light as a prism does, although relying on a different physical mechanism. The successor of HARPS — the world’s foremost exoplanet hunter — ESPRESSO will take the search for exoplanets to the next level, allowing astronomers to search for Earth-like planets around nearby stars with the finest toothcomb yet [1]. It will have many other science applications, including the search for possible variations in the constants of nature at different times in the life of the Universe, and in different directions, through the study of light from very distant quasars.

The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets. To the left of the image, we see the evening border of the exoplanet, where it transitions from day to night.2021-02-04T02:49:51+00:00monthlyhttps://hoyenelcosmos.com/2020/04/28/hubble-observa-la-fragmentacion-del-cometa-atlas/https://hoyenelcosmos.com/wp-content/uploads/2020/04/stsci-h-p2028b-f-compass-1252x736-1.pngSTScI-H-p2028b-f-compass-1252x736https://hoyenelcosmos.com/wp-content/uploads/2020/04/stsci-h-p2028b-d-1280x720_bw.pngSTScI-H-p2028b-d-1280x720_bwhttps://hoyenelcosmos.com/wp-content/uploads/2020/04/fragmentation_big_atlas_queiroz.jpgfragmentation_big_ATLAS_Queirozhttps://hoyenelcosmos.com/wp-content/uploads/2020/04/atlas3_crop.jpgatlas3_crophttps://hoyenelcosmos.com/wp-content/uploads/2020/04/low_stsci-h-p2028a-k-1340x520-1.pnglow_STScI-H-p2028a-k-1340x5202021-02-04T02:44:42+00:00monthlyhttps://hoyenelcosmos.com/2020/05/02/porque-el-sol-es-tan-diferente-de-otras-estrellas-similares/https://hoyenelcosmos.com/wp-content/uploads/2020/05/6l3idhbsolaractivity.gif6l3idHbSolarActivityhttps://hoyenelcosmos.com/wp-content/uploads/2020/05/12-figure6-1.png12-Figure6-1https://hoyenelcosmos.com/wp-content/uploads/2020/05/ssn_ciclosolar_actividad.jpgssn_ciclosolar_actividadhttps://hoyenelcosmos.com/wp-content/uploads/2020/05/sun_400x225_solar-flare.jpgsun_400x225_solar-flarehttps://hoyenelcosmos.com/wp-content/uploads/2020/05/exoplanet_yellow_star.jpgexoplanet_yellow_starhttps://hoyenelcosmos.com/wp-content/uploads/2020/04/dancingprom.gifdancingprom2021-02-04T02:44:31+00:00monthlyhttps://hoyenelcosmos.com/2020/05/03/como-ver-la-lluvia-de-meteoros-eta-acuaridas-2020/https://hoyenelcosmos.com/wp-content/uploads/2020/05/eta_aquariids_panorama_1.pngeta_aquariids_panorama_1https://hoyenelcosmos.com/wp-content/uploads/2020/05/eta_aquariids_panorama_2.pngeta_aquariids_panorama_2https://hoyenelcosmos.com/wp-content/uploads/2020/05/eta_aquariids_panorama.pngeta_aquariids_panoramahttps://hoyenelcosmos.com/wp-content/uploads/2020/05/lspn_comet_halley.jpgLspn_comet_halley2021-02-04T02:44:21+00:00monthlyhttps://hoyenelcosmos.com/2020/08/04/los-valles-en-marte-erosion-por-glaciares-o-lluvia/https://hoyenelcosmos.com/wp-content/uploads/2020/08/mars-and-arctic-superimposed_700-1.jpgMars-and-Arctic-superimposed_700-1https://hoyenelcosmos.com/wp-content/uploads/2020/08/devon-island_icecap_1200-700x368-1.jpgDevon-Island_iceCap_1200-700x3682021-02-04T02:44:08+00:00monthlyhttps://hoyenelcosmos.com/2020/09/03/caos-para-tres/https://hoyenelcosmos.com/wp-content/uploads/2020/09/eso2014b.jpgALMA and SPHERE view of GW Orionis (side-by-side)La imagen de ALMA (izquierda) muestra la estructura del disco, con el anillo más interno separado del resto del disco.

to a hypergiantLight travels through space at just under 300 000 kilometres per second! This staggering speed is used to calculate astronomical distances; although often misinterpreted as a unit of time (due to its misleading name), a light-year is actually a unit of astronomical distance, and is defined as the distance that light travels in a year. For reference, this is around nine trillion kilometres… but it’s a little tricky to visualise! With this in mind, 15 000 light-years may sound like a truly huge distance, but compared to the vastness of the cosmos, it’s really quite nearby. In fact, an object sitting 15 000 light-years away would not even be outside our home galaxy, the Milky Way. This is roughly the distance between us and a young super star cluster known as Westerlund 1, home to one of the largest stars ever discovered. Stars are classified according to their spectral type, surface temperature, and luminosity. While studying and classifying the cluster’s constituent stars, astronomers discovered that Westerlund 1 is home to one of the largest stars ever discovered, originally named Westerlund 1-26. It is a red supergiant (although sometimes classified as a hypergiant) with a radius over 1500 times that of our Sun. If Westerlund 1-26 were placed where our Sun is in our Solar System, it would extend out beyond the orbit of Jupiter. Most of Westerlund 1’s stars are thought to have formed in the same burst of activity, meaning that they have similar ages and compositions. The cluster is relatively young in astronomical terms — at around three million years old it is a baby compared to our own Sun, which is some 4.6 billion years old.2021-01-24T00:44:22+00:00monthlyhttps://hoyenelcosmos.com/2015/08/07/los-agujeros-negros-controlan-la-natalidad-estelar-en-galaxias-gigantes/https://hoyenelcosmos.com/wp-content/uploads/2015/08/2015-08-07-16-50-41-e1439169927399.jpg2015-08-07 16.50.412021-01-24T00:42:03+00:00monthlyhttps://hoyenelcosmos.com/2013/07/12/el-herrero-y-el-color-de-las-estrellas/https://hoyenelcosmos.com/wp-content/uploads/2013/07/125c3-estrellas-colores_temperaturas.jpg125c3-estrellas-colores_temperaturashttps://hoyenelcosmos.com/wp-content/uploads/2013/07/e6f6b-orion_estrellas_colores_constelacion.jpge6f6b-orion_estrellas_colores_constelacion2021-01-24T00:39:31+00:00monthlyhttps://hoyenelcosmos.com/2013/10/09/toby-jug-y-la-muerte-del-sol/https://hoyenelcosmos.com/wp-content/uploads/2013/10/eso1343a_toby_jug_nebula_945-e1406536018826.jpgeso1343a_toby_jug_nebula_945https://hoyenelcosmos.com/wp-content/uploads/2013/10/626e8-eso1343_nebulosa_reflexion_toby_jug_composicion.jpg626e8-eso1343_nebulosa_reflexion_toby_jug_composicion2021-01-24T00:39:09+00:00monthlyhttps://hoyenelcosmos.com/2017/07/27/tres-ciudades-en-orion/https://hoyenelcosmos.com/wp-content/uploads/2017/07/eso1723c_orion_population_vlt.jpgThe Orion Nebula showing three populations of young starsOmegaCAM — the wide-field optical camera on ESO’s VLT Survey Telescope (VST) — has captured the spectacular Orion Nebula and its associated cluster of young stars in great detail,  producing this beautiful new image. This famous object, the birthplace of many massive stars, is one of the closest stellar nurseries, at a distance of about 1350 light-years. On this plot different populations of young stars are marked in different colours. The blue ones are oldest and the red youngest, with green ones an intermediate age. These stars seems to have formed in three bursts of star formation during the last three million years.2021-01-24T00:38:35+00:00monthlyhttps://hoyenelcosmos.com/2012/07/13/muevete-al-rojo/https://hoyenelcosmos.com/wp-content/uploads/2012/07/redshift.jpgredShifthttps://hoyenelcosmos.com/wp-content/uploads/2012/07/d2ca4-800px-redshift_blueshift-sv_1.gifd2ca4-800px-redshift_blueshift-sv_1https://hoyenelcosmos.com/wp-content/uploads/2012/07/1c486-redshift.gif1c486-redshift2021-01-24T00:38:10+00:00monthlyhttps://hoyenelcosmos.com/2017/08/16/introspeccion/https://hoyenelcosmos.com/wp-content/uploads/2017/08/introspeccion-astrofotoperu.jpgIntrospeccion- astrofotoperuEsta foto es parte de nuestra galería en <a href="https://naricesdetycho.org/imagenes/introspeccion/" rel="noopener" target="_blank">"INTROSPECCIÓN"</a>2021-01-24T00:35:20+00:00monthlyhttps://hoyenelcosmos.com/2014/11/19/cuasares-paralelos/https://hoyenelcosmos.com/wp-content/uploads/2014/11/eso1438b.jpgSimulation of large scale structurehttps://hoyenelcosmos.com/wp-content/uploads/2014/11/eso1438a.jpgArtist’s impression of mysterious alignment of quasar rotation2022-07-25T00:40:02+00:00monthlyhttps://hoyenelcosmos.com/2017/08/17/ritmo-de-enanas-cafe/https://hoyenelcosmos.com/wp-content/uploads/2017/08/modelo_enana_cafe.pngmodelo_enana_cafehttps://hoyenelcosmos.com/wp-content/uploads/2017/08/neptuno_enana_cafe.pngNeptuno_enana_cafeArriba, Neptuno observado con luz infrarroja.

NGC 5253 is one of the nearest of the known Blue Compact Dwarf (BCD) galaxies, and is located at a distance of about 12 million light-years from Earth in the southern constellation of Centaurus. The most characteristic signature of these galaxies is that they harbour very active star-formation regions. This is in spite of their low dust content and comparative lack of elements heavier than hydrogen and helium, which are usually the basic ingredients for star formation. These galaxies contain molecular clouds that are quite similar to the pristine clouds that formed the first stars in the early Universe, which were devoid of dust and heavier elements. Hence, astronomers consider the BCD galaxies to be an ideal testbed for better understanding the primordial star-forming process. NGC 5253 does contain some dust and heavier elements, but significantly less than the Milky Way galaxy. Its central regions are dominated by an intense star forming region that is embedded in an elliptical main body, which appears red in Hubble’s image. The central starburst zone consists of a rich environment of hot, young stars concentrated in star clusters, which glow in blue in the image. Traces of the starburst itself can be seen as a faint and diffuse glow produced by the ionised oxygen gas. The true nature of BCD galaxies has puzzled astronomers for a long time. Numerical simulations following the current leading cosmological theory of galaxy formation, known as the Lambda Cold Dark Matter model, predict that there should be far more satellite dwarf galaxies orbiting big galaxies like the Milky Way. Astronomers refer to this discrepancy as the Dwarf Galaxy Problem. This galaxy is considered part of the Centaurus A/Messier 83 group of galaxies, which includes the famous radio galaxy Centaurus A and the spiral galaxy Messier 83. Astronomers have pointed out the possibility that the peculiar nature of NGC 5253 could result from a close encounter with Messier 83, its closer neighbour. This image was taken with the Hubble’s Advanced Camera for Surveys, combining visible and infrared exposures. The field of view in this image is approximately 3.4 by 3.4 arcminutes. A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Nikolaus Sulzenauer.2021-01-24T00:28:18+00:00monthlyhttps://hoyenelcosmos.com/2016/10/05/estrellas-detras-de-la-polvareda/https://hoyenelcosmos.com/wp-content/uploads/2016/10/eso1635a_messier70_comparison_vista.jpgComparisons between parts of the Messier 78 region in visible anThese comparison cutouts show how differently parts of this rich star-forming complex in Orion appear at different wavelengths.

Comet ISON was first spotted in our skies in September 2012, and will make its closest approach to the Sun in late November 2013. TRAPPIST–South has been monitoring comet ISON since mid-October, using broad-band filters like those used in this image. It has also been using special narrow-band filters which isolate the emission of various gases, allowing astronomers to count how many molecules of each type are released by the comet. Comet ISON was fairly quiet until 1 November 2013, when a first outburst doubled the amount of gas emitted by the comet. On 13 November, just before this image was taken, a second giant outburst shook the comet, increasing its activity by a factor of ten. It is now bright enough to be seen with a good pair of binoculars from a dark site, in the morning skies towards the East. Over the past couple of nights, the comet has stabilised at its new level of activity. These outbursts were caused by the intense heat of the Sun reaching ice in the tiny nucleus of the comet as it zooms toward the Sun, causing the ice to sublimate and throwing large amounts of dust and gas into space. By the time ISON makes its closest approach to the Sun on 28 November (at only 1.2 million kilometres from its surface — just a little less than the diameter of the Sun!), the heat will cause even more ice to sublimate. However, it could also break the whole nucleus down into small fragments, which would completely evaporate by the time the comet moves away from the Sun's intense heat. If ISON survives its passage near the Sun, it could then become spectacularly bright in the morning sky. The image is a composite of four different 30-second exposures through blue, green, red, and near-infrared filters. As the comet moved in front of the background stars, these appear as multiple coloured dots.

But, far beyond this cluster, and seen when the Universe was only about 600 million years old, is a very faint galaxy called A2744_YD4. New observations of this galaxy with ALMA, shown in red, have demonstrated that it is rich in dust.https://hoyenelcosmos.com/wp-content/uploads/2017/03/eso1708a_a2744_yd4_alma.jpgArtist’s impression of the remote dusty galaxy A2744_YD4This artist’s impression shows what the very distant young galaxy A2744_YD4 might look like. Observations using ALMA have shown that this galaxy, seen when the Universe was just 4% of its current age, is rich in dust. Such dust was produced by an earlier generation of stars and these observations provide insights into the birth and explosive deaths of the very first stars in the Universe.2021-01-24T00:04:02+00:00monthlyhttps://hoyenelcosmos.com/2017/06/22/resuelven-el-enigma-de-las-espiculas-solares/https://hoyenelcosmos.com/wp-content/uploads/2017/06/spicules_sst.jpgspicules_sst2021-01-24T00:02:37+00:00monthlyhttps://hoyenelcosmos.com/2012/05/23/formacion-estelar-o-el-misterio-de-las-vacas-magneticas/https://hoyenelcosmos.com/wp-content/uploads/2012/05/e610d-vacas_magneticas_animales.jpge610d-vacas_magneticas_animaleshttps://hoyenelcosmos.com/wp-content/uploads/2012/05/333be-disco_formacion_lineas_campo_magnetico.jpg333be-disco_formacion_lineas_campo_magnetico2021-01-24T00:01:46+00:00monthlyhttps://hoyenelcosmos.com/2015/02/18/el-extrano-caso-de-la-enana-perdida/https://hoyenelcosmos.com/wp-content/uploads/2015/02/eso1506c.jpgWide-field view of the sky around the unusual binary star V471 TCampo de estrellas entorno a V471.

As the star was monitored using the HAWK-I instrument on ESO’s Very Large Telescope three planets passed across the disc of the star, each causing some of its light to be blocked. This historic light curve shows for the first time three temperate Earth-sized planets, two of them in the habitable zone, passing in front of their star.https://hoyenelcosmos.com/wp-content/uploads/2017/02/eso1706n_trappist.jpgArtist’s impression of the TRAPPIST-1 systemThis artist’s impression displays TRAPPIST-1 and its planets reflected in a surface. The potential for water on each of the worlds is also represented by the frost, water pools, and steam surrounding the scene. The image appears on the 22 February 2017 Nature cover.https://hoyenelcosmos.com/wp-content/uploads/2017/02/eso1706a_trappist.jpgArtist’s impression of the TRAPPIST-1 planetary systemThis artist’s impression shows the view from the surface of one of the planets in the TRAPPIST-1 system. At least seven planets orbit this ultra cool dwarf star 40 light-years from Earth and they are all roughly the same size as the Earth. They are at the right distances from their star for liquid water to exist on the surfaces of several of them. This artist’s impression is based on the known physical parameters for the planets and stars seen, and uses a vast database of objects in the Universe.2023-07-28T18:34:36+00:00monthlyhttps://hoyenelcosmos.com/2016/10/11/manchas-en-proxima-centauri/https://hoyenelcosmos.com/wp-content/uploads/2016/10/basesuninterior.jpgA low-mass red dwarf star about 31 light years away from Earth.An artist's illustration depicts the interior of a low-mass star, such as the one seen in an X-ray image from Chandra in the inset. Such stars have different interior structures than our Sun. A new study looking at four of these low-mass stars shows the strength of magnetic fields of these stars - which is revealed by the amount of X-ray emission from the stars - are similar to those of more massive ones like the Sun. This discovery may have profound implications for understanding how the magnetic field in the Sun and stars like it are generated.https://hoyenelcosmos.com/wp-content/uploads/2016/10/640px-new_shot_of_proxima_centauri_our_nearest_neighbour.jpg640px-new_shot_of_proxima_centauri_our_nearest_neighbourImagen de Proxima Centauri tomada con del Telescopio Espacial Hubble.https://hoyenelcosmos.com/wp-content/uploads/2016/10/zoomproximacenb.jpgzoomproximacenb2021-01-23T22:27:32+00:00monthlyhttps://hoyenelcosmos.com/2014/10/24/las-familias-cometarias-de-beta-pictoris/https://hoyenelcosmos.com/wp-content/uploads/2014/10/eso1024a.jpgExoplanet caught on the moveImagen de Beta Pictorishttps://hoyenelcosmos.com/wp-content/uploads/2014/10/eso1432a-e1413998497525.jpgArtist’s impression of exocomets around Beta Pictoris2021-01-23T22:27:07+00:00monthlyhttps://hoyenelcosmos.com/2018/07/01/observan-el-campo-magnetico-de-la-supernova-1987a/https://hoyenelcosmos.com/wp-content/uploads/2018/07/composite_image_of_supernova_1987a.jpgComposite_image_of_Supernova_1987AImagen de SN 1987A, compuesta por datos en ondas de radio, luz visible, infraroja y rayos X.https://hoyenelcosmos.com/wp-content/uploads/2018/07/sn-1987a-mag-map_gz.jpgSN-1987A-mag-map_GZhttps://hoyenelcosmos.com/wp-content/uploads/2018/07/new_image_of_sn_1987a_midres.jpgNew image of SN 1987Ahttps://hoyenelcosmos.com/wp-content/uploads/2018/07/sn_1987a_hst.jpgSN_1987A_HSTSupernova SN 1987A.2021-01-23T22:00:12+00:00monthlyhttps://hoyenelcosmos.com/2018/06/13/alma-descubre-tres-planetas-infantes/https://hoyenelcosmos.com/wp-content/uploads/2018/06/nrao18cb07_artistimpression_formacion_exoplanetas.jpgnrao18cb07_artistimpression_Formacion_exoplanetashttps://hoyenelcosmos.com/wp-content/uploads/2018/06/eso1818d_eso_campo_hd163296_disco.jpgSurroundings of the young star HD 163296This wide-field image shows the surroundings of the young star HD 163296 in the rich constellation of Sagittarius (The Archer).

Stars, gas, and dust flow from the large spiral galaxy, NGC 3808, forming an enveloping arm around its companion. The shapes of both galaxies have been distorted by their gravitational interaction. Arp 87 is located in the constellation of Leo, the Lion, approximately 300 million light-years away from Earth. Arp 87 appears in Arp's Atlas of Peculiar Galaxies. As also seen in similar interacting galaxies, the corkscrew shape of the tidal material suggests that some stars and gas drawn from the larger galaxy have been caught in the gravitational pull of the smaller one. This image was taken in February 2007 with Hubble's Wide Field Planetary Camera 2 detector.https://hoyenelcosmos.com/wp-content/uploads/2017/07/hs-2002-11-e-full_galaxy_streams_med.jpghs-2002-11-e-full_galaxy_streams_medhttps://hoyenelcosmos.com/wp-content/uploads/2017/07/146221_m101_galaxia_bulbo.jpg146221_M101_Galaxia_bulbo2021-01-23T21:53:28+00:00monthlyhttps://hoyenelcosmos.com/2013/11/23/rayos-cosmicos-y-cambio-climatico/https://hoyenelcosmos.com/wp-content/uploads/2013/11/cosmic_r.jpgcosmic_rhttps://hoyenelcosmos.com/wp-content/uploads/2013/11/130214-fermi-cosmic-rays-1.jpg130214-fermi-cosmic-rays-12021-01-23T21:50:43+00:00monthlyhttps://hoyenelcosmos.com/2014/04/08/el-origen-cosmico-del-agua/https://hoyenelcosmos.com/wp-content/uploads/2014/04/water_dh_05162015.jpgwater_dh_05162015Proporciones
