Published First pictures from Euclid satellite reveal billions of orphan stars



The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
Published Potentially habitable 'exo-Venus' with Earth-like temperature discovered



Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.
Published Complete stellar collapse: Unusual star system proves that stars can die quietly



University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.
Published Webb Telescope offers first glimpse of an exoplanet's interior



A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Hubble views the dawn of a sun-like star



Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as 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.
Published Robotic 'SuperLimbs' could help moonwalkers recover from falls



SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks.
Published Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3



Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.
Published WASP-193b, a giant planet with a density similar to that of cotton candy



Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star.
Published Researchers discover the universe's oldest stars in our own galactic backyard



Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.
Published Squeezed by neighbors, planet glows with molten lava



Astrophysicists discovered that an exoplanet is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.
Published Astrophysicists discover a novel method for hunting the first stars



A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
Published Possible atmosphere surrounding rocky exoplanet



Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.
Published Iron fingerprints in nearby active galaxy



After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151.
Published Venus has almost no water: A new study may reveal why



Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.
Published Astronomers observe elusive stellar light surrounding ancient quasars



Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.
Published New discoveries about Jupiter's magnetosphere



New discoveries about Jupiter could lead to a better understanding of Earth's own space environment and influence a long-running scientific debate about the solar system's largest planet.
Published Webb telescope probably didn't find life on an exoplanet -- yet



Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced gas.
Published 75,000-year-old female Neanderthal from cave where species buried their dead



A new documentary has recreated the face of a 75,000-year-old female Neanderthal whose flattened skull was discovered and rebuilt from hundreds of bone fragments by a team of archaeologists and conservators.
Published A 'cosmic glitch' in gravity



Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.
Published Earth-like environment likely on ancient Mars



A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake.
