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...
Large amounts of stars are being born at the center of NGC 4383, a peculiar galaxy located 74 million light-years away in the constellation of Coma Berenices....
Using data from ESA’s Gaia mission, astronomers have discovered a nearby binary system composed of a giant star orbiting a dormant black hole of of stellar...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a spectacular image of I Zwicky 18 (I Zw 18 for short), the archetypal extremely...
Dubbed Shakti and Shiva, the newly-identified structures are between 12 and billion years old — so ancient they likely formed before even the oldest...
The rapid neutron capture process, or the so-called r-process, occurs in neutron-rich environments such as neutron star mergers or certain types of supernovae....
The oldest of these stars is 1.5 billion years old while the youngest is only 100 million years old, according to a paper published in the Astrophysical...
Ancient starburst galaxies that formed 2-3 billion years after the Big Bang are unusually hot and contain unexpected elements, like nickel, according to...
The NASA/ESA/CSA James Webb Space Telescope has captured a striking new photo of the barred irregular galaxy NGC 6822.
This image shows the irregular galaxy...
