Astronomers using the NASA/ESA Hubble Space Telescope have found definitive evidence that the young Milky Way swallowed a dwarf galaxy just two billion...
Roughly 660 million years after the Big Bang, a strange bright red spot has been hiding in plain sight in one of the deepest fields ever imaged by the...
New simulations suggest supernova explosions of the Universe’s first stars scattered the ingredients for rocky planets only 100 million years after the...
Astronomers using the NASA/ESA Hubble Space Telescope have captured this vivid image of NGC 6426, an ancient globular cluster in the Milky Way’s outer...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found an enormous black hole in the early Universe that appears to predate its own host...
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b,...
The newly-discovered star, SDSS J0715-7334, formed in the halo of the Large Magellanic Cloud and migrated to our Milky Way Galaxy billions of years ago,...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected phosphine (PH3) in the atmosphere of Wolf 1130C, a metal-poor brown dwarf within...
Using data gathered by NSF’s Gemini South telescope and the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected signatures of methane...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected oxygen in the most distant confirmed galaxy ever found, JADES-GS-z14-0....
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
Astronomers using the Immersion GRating INfrared Spectrograph (IGRINS) instrument on the Gemini South telescope have examined the atmosphere of WASP-121b,...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected a population of 64 brown dwarf candidates with masses ranging from 50 to 84...
Using data from ESA’s Gaia mission, astronomers have found a large number of metal-poor stars older than 13 billion years on orbits similar to that of...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected trace amounts of hydrogen sulfide in the atmosphere of the Jupiter-sized exoplanet...
Astronomers at MIT have discovered thee extremely ancient stars in the Milky Way’s halo, a cloud of stars that envelopes the entire main Galactic disk....
Using the Gemini High-resolution Optical SpecTrograph (GHOST), which is attached to the 8.1-m Gemini South telescope at Cerro Pachón, Chile, astronomers...
