During the first 500 million years of cosmic history, the first stars and galaxies formed, seeding the Universe with heavy elements and eventually reionizing...
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects: hydrogen burning Population III...
Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...
Using infrared spectral data from NASA’s Spitzer Space Telescope, Instituto de Astrofísica de Canarias astronomer has detected the aromatic amino acid...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
The new observations from the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope show that the main-belt comet 238P/Read...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
The seven galaxies highlighted in this new image from the NASA/ESA/CSA James Webb Space Telescope have been confirmed to be at a distance that astronomers...
Hercules X-1 is an X-ray binary system in which a neutron star is drawing material away from a Sun-like star. This neutron star’s accretion disk is unique...
Astronomers using NASA’s Infrared Telescope Facility (IRTF) telescope at Mauna Kea Observatory have captured and analyzed visible and near-infrared reflectance...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured the reflectance spectrum of the double-ringed centaur 10199 Chariklo and observed...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have validated the discovery of a warm, 0.99 Earth-radius exoplanet interior to the habitable...
Titan, the largest moon of Saturn, is the only moon in the Solar System with a dense atmosphere, and it is also the only planetary body other than Earth...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
WD J2147-4035, an 11-billion-year-old white dwarf located 91 light-years away in the constellation of Grus, is accreting debris from orbiting planetesimals,...
Astronomers have analyzed publicly available data from the Mid-Infrared Instrument (MIRI) on the NASA/ESA/CSA James Webb Space Telescope for three Seyfert...
