This is the first time astronomers have directly observed more than one planet orbiting a star similar to the Sun. The image was captured by blocking the light from the young, Sun-like star (on the top left corner) using a coronagraph, which allows for the fainter planets to be detected. The bright and dark rings we see on the star’s image are optical artefacts. The two planets are visible as two bright dots in the centre and bottom right of the frame.https://adastradaily.com/wp-content/uploads/2024/03/ajad11ebf18_hr.jpgajad11ebf18_hr2024-03-03T22:46:03+00:00monthlyhttps://adastradaily.com/2024/03/03/unlocking-europas-icy-secrets-alma-observations-reveal-dynamic-subsurface-and-shape-future-missions/https://adastradaily.com/wp-content/uploads/2024/03/europa.jpegeuropahttps://adastradaily.com/wp-content/uploads/2024/03/psjad251cf1_hr.jpgpsjad251cf1_hr2024-03-03T22:33:24+00:00monthlyhttps://adastradaily.com/2024/03/04/the-seti-ellipsoid-strategy-and-its-quest-for-extraterrestrial-technosignatures/https://adastradaily.com/wp-content/uploads/2024/03/eso1401a.jpgComposite image of Supernova 1987AThis image shows the remnant of Supernova 1987A seen in light of very different wavelengths. ALMA data (in red) shows newly formed dust in the centre of the remnant. Hubble (in green) and Chandra (in blue) data show where the expanding shock wave is colliding with a ring of material around the supernova. This ring was initially lit up by the ultraviolet flash from the original explosion, but over the past few years the ring material has brightened considerably as it collides with the expanding shockwave.https://adastradaily.com/wp-content/uploads/2024/03/ajad2064f2_hr.jpgajad2064f2_hr2024-03-03T22:22:02+00:00monthlyhttps://adastradaily.com/2024/03/02/alma-uncovers-early-grain-growth-and-complex-magnetic-fields-in-orion-protostars/https://adastradaily.com/wp-content/uploads/2024/02/weic2315b.jpgThe Orion Bar region (NIRCam image)An international team of scientists have used data collected by the NASA/ESA/CSA James Webb Space Telescope to detect a molecule known as the methyl cation (CH3+) for the first time, located in the protoplanetary disc surrounding a young star. They accomplished this feat with a cross-disciplinary expert analysis, including key input from laboratory spectroscopists. The vital role of CH3+ in interstellar carbon chemistry has been predicted since the 1970s, but Webb’s unique capabilities have finally made observing it possible — in a region of space where planets capable of accommodating life could eventually form. This image is NIRCam’s view of the Orion Bar region studied by the team of astronomers. Bathed in harsh ultraviolet light from the stars of the Trapezium Cluster, it is an area of intense activity, with star formation and active astrochemistry. This made it a perfect place to study the exact impact that ultraviolet radiation has on the molecular makeup of the discs of gas and dust that surround new stars. The radiation erodes the nebula’s gas and dust in a process known as photoevaporation; this creates the rich tapestry of cavities and filaments that fill the view. The radiation also ionises the molecules, causing them to emit light — not only does this create a beautiful vista, it also allows astronomers to study the molecules using the spectrum of their emitted light obtained with Webb’s MIRI and NIRSpec instruments. The two very large, bright stars are two of the three stars in the θ² Orionis system — the Trapezium Cluster is also known as θ¹ Orionis. The brightest star here, θ² Orionis A, is surrounded by particularly bright and red puffs of dust, which are reflecting the star’s light towards Earth. Its great brightness — it is visible with the naked eye — is due to the fact that θ² Orionis A is itself a ternary system made of three closely bound bright stars.  There are more proplyds visible in this image than just d203-50https://adastradaily.com/wp-content/uploads/2024/02/apjlad27d4f10c_hr-1.jpgapjlad27d4f10c_hr-1https://adastradaily.com/wp-content/uploads/2024/02/apjlad27d4f10c_hr.jpgapjlad27d4f10c_hr2024-03-01T07:23:16+00:00monthlyhttps://adastradaily.com/2024/02/29/ultradistant-comet-sheds-light-on-early-solar-system/https://adastradaily.com/wp-content/uploads/2024/02/stsci-01evvb4z8yqxhfcepf2gxwenyg.pngSTScI-01EVVB4Z8YQXHFCEPF2GXWENYGhttps://adastradaily.com/wp-content/uploads/2024/02/ajad2500f1_hr.jpgajad2500f1_hr2024-03-01T07:04:07+00:00monthlyhttps://adastradaily.com/galaxies/2024-02-26T06:22:51+00:00weekly0.6https://adastradaily.com/solar-system/2024-02-26T06:22:50+00:00weekly0.6https://adastradaily.com/black-holes/2024-02-26T06:22:49+00:00weekly0.6https://adastradaily.com/moon/2024-02-26T06:22:44+00:00weekly0.6https://adastradaily.com/2024/02/27/unveiling-the-origins-of-jupiters-irregular-satellites-a-spectroscopic-journey-through-time-and-space/https://adastradaily.com/wp-content/uploads/2024/02/20131017_himalia_lor_0035085119_0x630_sci_1.png20131017_himalia_LOR_0035085119_0X630_SCI_1https://adastradaily.com/wp-content/uploads/2024/02/jupiter_irregular_moon_orbits_jan_2021.pngjupiter_irregular_moon_orbits_jan_20212024-02-25T22:54:34+00:00monthlyhttps://adastradaily.com/2024/02/26/chandra-telescope-unveils-mysteries-of-supernova-2023ixf-a-glimpse-into-stellar-death-and-cosmic-dynamics/https://adastradaily.com/wp-content/uploads/2024/02/m101.jpgm101https://adastradaily.com/wp-content/uploads/2024/02/hiramatsu-et-al.-2023.jpghiramatsu-et-al.-20232024-02-25T22:52:27+00:00monthlyhttps://adastradaily.com/2024/02/25/unlocking-the-moons-frozen-mysteries-new-insights-into-lunar-cold-traps-and-volatile-reserves/https://adastradaily.com/wp-content/uploads/2024/02/20220317_on_moon-shadowed-craters.jpg_20220317_on_moon-shadowed-cratershttps://adastradaily.com/wp-content/uploads/2024/02/image2.jpgimage2https://adastradaily.com/wp-content/uploads/2024/02/image1.jpgimage12024-02-25T21:32:48+00:00monthlyhttps://adastradaily.com/2024/02/23/illuminating-m87s-black-hole-and-jet-formation/https://adastradaily.com/wp-content/uploads/2024/02/opo9943b.jpgClose-up look at a jet near a black hole in galaxy M87 (ground-bThis radio image of the galaxy M 87, taken with the Very Large Array (VLA) radio telescope in February 1989, shows giant bubble-like structures where radio emission is thought to be powered by the jets of subatomic particles coming from the the galaxy's central black hole.

This is the first time that ALMA has ever observed the surface of a star and this first attempt has resulted in the highest-resolution image of Betelgeuse available. Betelgeuse is one of the largest stars currently known — with a radius around 1400 times larger than the Sun’s in the millimeter continuum. About 600 light-years away in the constellation of Orion (The Hunter), the red supergiant burns brightly, causing it to have only a short life expectancy. The star is just about eight million years old, but is already on the verge of becoming a supernova. When that happens, the resulting explosion will be visible from Earth, even in broad daylight. The star has been observed in many other wavelengths, particularly in the visible, infrared, and ultraviolet. Using ESO’s Very Large Telescope astronomers discovered a vast plume of gas almost as large as our Solar System. Astronomers have also found a gigantic bubble that boils away on Betelgeuse’s surface. These features help to explain how the star is shedding gas and dust at tremendous rates (eso0927, eso1121). In this picture, ALMA observes the hot gas of the photosphere of Betelgeuse at sub-millimeter wavelengths — where localised increased temperatures explain why it is not symmetric. Scientifically, ALMA can help us to understand the extended atmospheres of these hot, blazing stars.

This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star formation. N159 is located over 160 000 light-years away. It resides just south of the Tarantula Nebula (heic1402), another massive star-forming complex within the LMC. It was previously imaged by Hubble’s Wide Field Planetary Camera 2, which also resolved the Papillon Nebula for the first time.https://adastradaily.com/wp-content/uploads/2024/02/ajad19cdf8_hr.jpgajad19cdf8_hr2024-02-14T06:36:11+00:00monthlyhttps://adastradaily.com/2024/02/13/linking-deep-ocean-isotopes-to-cosmic-phenomena/https://adastradaily.com/wp-content/uploads/2024/02/eso1733n-1358570759-e1707891184220.jpgHubble observes first kilonovaOn 17 August 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo Interferometerboth detected gravitational waves from the collision between two neutron stars. Within 12 hours observatories had identified the source of the event within the lenticular galaxy NGC 4993, shown in this image gathered with the NASA/ESA Hubble Space Telescope. The associated stellar flare, a kilonova, is clearly visible in the Hubble observations. This is the first time the optical counterpart of a gravitational wave event was observed. Hubble observed the kilonova gradually fading over the course of six days, as shown in these observations taken in between 22 and 28 August (insets).2024-02-14T06:11:35+00:00monthlyhttps://adastradaily.com/2024/02/12/new-insights-unveil-titanias-geological-mysteries/https://adastradaily.com/wp-content/uploads/2024/02/titania.jpgScreenshotScreenshothttps://adastradaily.com/wp-content/uploads/2024/02/psjad04d6f4_hr.jpgpsjad04d6f4_hr2024-02-12T07:24:11+00:00monthlyhttps://adastradaily.com/2024/02/11/astronomers-discover-most-distant-obscured-radio-loud-agn-with-jwst/https://adastradaily.com/wp-content/uploads/2024/02/nraoaui.jpgScreenshotScreenshothttps://adastradaily.com/wp-content/uploads/2024/02/apjlad11eef2_hr.jpgapjlad11eef2_hr2024-02-11T07:59:11+00:00monthlyhttps://adastradaily.com/2024/02/10/hubble-survey-unveils-new-globular-cluster-catalogs-in-spiral-galaxies/https://adastradaily.com/wp-content/uploads/2024/02/mayall-ii.jpegMayall-IIhttps://adastradaily.com/wp-content/uploads/2024/02/ajad1889f7_hr.jpgajad1889f7_hr2024-02-10T06:25:55+00:00monthlyhttps://adastradaily.com/2024/02/09/revolutionary-findings-on-mercury-reveal-a-volatile-rich-geography/https://adastradaily.com/wp-content/uploads/2024/02/pia14856_modest.jpgPIA14856_modesthttps://adastradaily.com/wp-content/uploads/2024/02/james-stuby-based-on-nasa-images.jpgjames-stuby-based-on-nasa-images2024-02-09T07:39:36+00:00monthlyhttps://adastradaily.com/2024/02/08/jwst-observes-highly-collimated-atomic-jet-from-a-dim-protostar/https://adastradaily.com/wp-content/uploads/2024/02/potw2107a-1.jpgTantrums of a Baby StarHerbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating amongst the surrounding gas and stars.

Prior to its discovery in 1977 by the American astronomer R. D. Schwartz, the exact mechanism by which these multi-coloured objects formed was unknown. Before 1997 it was theorised by Schwartz and others that the objects could be a type of reflection nebula, or a type of shock wave formed from the gas emitted from a star interacting with the surrounding matter. The mystery was finally solved when a protostar, unseen in this image, was discovered at the centre of the long jets of matter. The outflows of matter, some 10 light-years across, were ejected from the newly born star and violently propelled outwards at speeds of over 150 kilometres per second. Upon reaching the surrounding gas, the collision created the bright shock waves seen here.https://adastradaily.com/wp-content/uploads/2024/02/apjlad1de3f1_hr.jpgapjlad1de3f1_hrhttps://adastradaily.com/wp-content/uploads/2024/02/potw2107a.jpgTantrums of a Baby StarHerbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating amongst the surrounding gas and stars.

One of the biggest and brightest spiral galaxies in the night sky, Messier 101 is also the subject of one of Hubble's most famous images (heic0602). Like the Milky Way, Messier 101 is not alone, with smaller dwarf galaxies in its neighbourhood. NGC 5477, one of these dwarf galaxies in the Messier 101 group, is the subject of this image from the NASA/ESA Hubble Space Telescope. Without obvious structure, but with visible signs of ongoing starbirth, NGC 5477 looks much like an archetypal dwarf irregular galaxy. The bright nebulae that extend across much of the galaxy are clouds of glowing hydrogen gas in which new stars are forming. These glow pinkish red in real life, although the selection of green and infrared filters through which this image was taken makes them appear almost white. The observations were taken as part of a project to measure accurate distances to a range of galaxies within about 30 million light-years from Earth, by studying the brightness of red giant stars. In addition to NGC 5477, the image includes numerous galaxies in the background, including some that are visible right through NGC 5477. This serves as a reminder that galaxies, far from being solid, opaque objects, are actually largely made up of the empty space between their stars. This image is a combination of exposures taken through green and infrared filters using Hubble's Advanced Camera for Surveys. The field of view is approximately 3.3 by 3.3 arcminutes. https://adastradaily.com/wp-content/uploads/2024/02/ngc-5477-esahubble-nasa.jpgAn archetypal dwarf galaxyThe constellation of Ursa Major (The Great Bear) is home to Messier 101, the Pinwheel Galaxy.

This serves as a reminder that galaxies, far from being solid, opaque objects, are actually largely made up of the empty space between their stars. This image is a combination of exposures taken through green and infrared filters using Hubble's Advanced Camera for Surveys. The field of view is approximately 3.3 by 3.3 arcminutes. 2024-02-05T07:01:16+00:00monthlyhttps://adastradaily.com/2024/02/04/new-model-reveals-dimorphoss-post-dart-impact-transformation/https://adastradaily.com/wp-content/uploads/2024/02/twin_tail_revealed_in_new_hubble_image_of_didymos-dimorphos_system_following_dart_impact-1860x1200-1.jpgTwin_tail_revealed_in_new_Hubble_image_of_Didymos-Dimorphos_system_following_DART_impact-1860x1200https://adastradaily.com/wp-content/uploads/2024/02/dimorphos-taken-by-the-draco-imager-on-nasas-dart-mission-2-seconds-before-impact-nasa-johns-hopkins-apl.jpgdimorphos-taken-by-the-draco-imager-on-nasas-dart-mission-2-seconds-before-impact-nasa-johns-hopkins-aplhttps://adastradaily.com/wp-content/uploads/2024/02/dart-mission-nasa.gifdart-mission-nasahttps://adastradaily.com/wp-content/uploads/2024/02/psjad0b07f4_hr.jpgpsjad0b07f4_hr2024-02-04T02:14:06+00:00monthlyhttps://adastradaily.com/2024/02/03/new-observations-challenge-long-standing-cosmic-ray-theories-at-cassiopeia-a/https://adastradaily.com/wp-content/uploads/2024/02/cas-a.jpgcas Ahttps://adastradaily.com/wp-content/uploads/2024/02/apjlad1d62f1_hr.jpgapjlad1d62f1_hr2024-02-03T06:28:05+00:00monthlyhttps://adastradaily.com/2024/02/02/galactic-sprinters-high-velocity-stars-unveil-cosmic-mysteries/https://adastradaily.com/wp-content/uploads/2024/02/potw1636a.jpgInto the stormThis shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud (LMC). This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star formation. N159 is located over 160 000 light-years away. It resides just south of the Tarantula Nebula (heic1402), another massive star-forming complex within the LMC. It was previously imaged by Hubble’s Wide Field Planetary Camera 2, which also resolved the Papillon Nebula for the first time.https://adastradaily.com/wp-content/uploads/2024/02/hs-2009-03-a-web_print.jpgHs-2009-03-a-web_print2024-02-02T06:43:13+00:00monthlyhttps://adastradaily.com/2024/01/31/innovative-study-suggests-primordial-black-holes-could-explain-anomalies-in-cosmic-lensing/https://adastradaily.com/wp-content/uploads/2024/01/universe-10-00037-g001.pnguniverse-10-00037-g001https://adastradaily.com/wp-content/uploads/2024/01/opo2004a.jpgMosaic of Gravitationally Lensed QuasarsEach of these Hubble Space Telescope snapshots reveals four distorted images of a background quasar surrounding the central core of a foreground massive galaxy. The multiple quasar images were produced by the gravity of the foreground galaxy, which is acting like a magnifying glass by warping the quasar’s light in an effect called gravitational lensing. Quasars are extremely distant cosmic streetlights produced by active black holes. The light rays from each lensed quasar image take a slightly different path through space to reach Earth. The pathway’s length depends on the amount of matter that is distorting space along the line of sight to the quasar. To trace each pathway, the astronomers monitor the flickering of the quasar’s light as its black hole gobbles up material. When the light flickers, each lensed image brightens at a different time. This flickering sequence allows researchers to measure the time delays between each image as the lensed light travels along its path to Earth. These time-delay measurements helped astronomers calculate how fast the universe is growing, a value called the Hubble constant. The Hubble images were taken between 2003 and 2004 with the Advanced Camera for Surveys.

The foreground galaxy smears the image of the background quasar into a bright arc (left) and creates a total of four images — three of which can be seen within the arc.2024-01-31T15:38:59+00:00monthlyhttps://adastradaily.com/2024/02/01/new-insights-into-venuss-magnetic-barrier-unraveling-the-mysteries-of-solar-wind-interactions/https://adastradaily.com/wp-content/uploads/2024/01/nasa-jpl-caltech-.jpgNASA : JPL Caltechhttps://adastradaily.com/wp-content/uploads/2024/01/compare_wispr_3rdflyby-1.webpcompare_wispr_3rdflyby-1https://adastradaily.com/wp-content/uploads/2024/01/magellan-teamjplusgs.jpgmagellan-teamjplusgs2024-01-29T00:33:47+00:00monthlyhttps://adastradaily.com/2024/01/30/james-webb-space-telescope-unveils-key-insights-into-protoplanetary-disk-dynamics-around-young-star/https://adastradaily.com/wp-content/uploads/2024/01/hste28093jwst-3-color-composite-image-of-tau-042021-the-full-field-of-view-spans-18.-the-0.8-2-and-7.7-cebcm-images-are-rendered-using-a-logarithmic-stretch-in-the-blue-green-and-red-ch.jpegHST–JWST 3-color composite image of Tau 042021; the full field of view spans 18''.

It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape.   Although we cannot see the event horizon itself, because it cannot emit light, glowing gas orbiting around the black hole reveals a telltale signature: a dark central region (called a shadow) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. The image of the Sgr A* black hole is an average of the different images the EHT Collaboration has extracted from its 2017 observations.  In addition to other facilities, the EHT network of radio observatories that made this image possible includes the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder EXperiment (APEX) in the Atacama Desert in Chile, co-owned and co-operated by ESO is a partner on behalf of its member states in Europe.https://adastradaily.com/wp-content/uploads/2024/01/a-sharper-look-at-the.jpga-sharper-look-at-thehttps://adastradaily.com/wp-content/uploads/2024/01/apjad07d4f1_hr-1.jpgapjad07d4f1_hr-1https://adastradaily.com/wp-content/uploads/2024/01/apjad07d4f1_hr.jpgapjad07d4f1_hr2024-01-16T01:15:48+00:00monthlyhttps://adastradaily.com/2024/01/06/astro-101-quasars/https://adastradaily.com/wp-content/uploads/2024/01/quasar-dalle.pngQuasar (DALLE)2024-01-15T23:43:11+00:00monthlyhttps://adastradaily.com/2024/01/15/pluto-charon-crater-research-reveals-new-insights/https://adastradaily.com/wp-content/uploads/2024/01/stsci-01ewxhzg0kkegnd7ycwkgja7br.pngstsci-01ewxhzg0kkegnd7ycwkgja7brhttps://adastradaily.com/wp-content/uploads/2024/01/psjacf7bef3_hr-1.jpgpsjacf7bef3_hr-1https://adastradaily.com/wp-content/uploads/2024/01/psjacf7bef3_hr.jpgpsjacf7bef3_hrhttps://adastradaily.com/wp-content/uploads/2024/01/psjacf7bef2_hr.jpgpsjacf7bef2_hrhttps://adastradaily.com/wp-content/uploads/2024/01/plutocharonnewhorizons.jpgplutocharonnewhorizons2024-01-15T09:05:47+00:00monthlyhttps://adastradaily.com/2024/01/14/an-astronomical-mystery-the-enigmatic-star-zng-1-in-cluster-m5/https://adastradaily.com/wp-content/uploads/2024/01/m5.jpgm5https://adastradaily.com/wp-content/uploads/2024/01/potw1118a-jpg.webppotw1118a-jpg2024-01-15T05:48:16+00:00monthlyhttps://adastradaily.com/2024/01/06/astro-101-barred-spiral-galaxies/https://adastradaily.com/wp-content/uploads/2024/01/barred-spiral-galaxy-ngc-4535-nasa-1.jpgBarred Spiral Galaxy NGC 4535 (NASA)2024-01-15T05:39:29+00:00monthlyhttps://adastradaily.com/2024/01/06/astro-101-vesta/2024-01-15T05:37:57+00:00monthlyhttps://adastradaily.com/2024/01/06/astro-101-triton/https://adastradaily.com/wp-content/uploads/2024/01/triton-nasa-voyager-2.jpgTriton (NASA Voyager 2)2024-01-15T05:36:12+00:00monthlyhttps://adastradaily.com/2024/01/06/astro-101-globular-clusters/https://adastradaily.com/wp-content/uploads/2024/01/globular-cluster-ngc-6388-nasa-eso.jpgThe globular cluster NGC 6388, observed by the NASA/ESA Hubble SThis image from the NASA/ESA Hubble Space Telescope shows NGC 6388, a dynamically middle-aged globular cluster in the Milky Way. While the cluster formed in the distant past (like all globular clusters, it is over ten billion years old), a study of the distribution of bright blue stars within the cluster shows that it has aged at a moderate speed, and its heaviest stars are in the process of migrating to the centre. A new study using Hubble data has discovered that globular clusters of the same age can have dramatically different distributions of blue straggler stars within them, suggesting that clusters can age at substantially different rates.2024-01-15T05:34:15+00:00monthlyhttps://adastradaily.com/2024/01/02/astro101-gravitational-waves/https://adastradaily.com/wp-content/uploads/2024/01/dallc2b7e-2024-01-02-22.35.43-depict-a-cosmic-scene-showcasing-gravitational-waves-in-outer-space.-the-image-should-capture-the-curvature-and-distortion-of-space-time-caused-by-the.pngDALL·E 2024-01-02 22.35.43 - Depict a cosmic scene showcasing gravitational waves in outer space.
