Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted early galaxies with stellar bars — elongated features of stars stretching...
Intracluster light is diffuse light from stars that are gravitationally bound not to individual member galaxies, but to the halo of galaxy clusters. In...
The light from these four galaxies has taken more than 13.4 billion years to reach us, as they date back to less than 400 million years after the Big Bang,...
The two newfound galaxies, dubbed GLASS-z12 and GLASS-z10, existed approximately 350 and 450 million years after the Big Bang.
GLASS-z12 (redshift of 12.5)...
The newly-discovered core-collapse supernova, or Type II supernova, seen at a lookback time of approximately 11.5 billion years, is strongly lensed by...
Nicknamed Quyllur, the newly-detected red supergiant candidate is so far away that its light has taken 10.7 billion years to reach Earth.
This Webb image...
Astronomers say we may be witnessing a merger of two small galaxies just 400 million years after the Big Bang.
The galaxy cluster MACS0647 acts as a cosmic...
The red quasar the NASA/ESA/CSA James Webb Space Telescope observed, called SDSS J165202.64+172852.3 (SDSSJ1652 for short), resides in a very dense environment...
Using 18 all-sky maps produced by NASA’s Near-Earth Object Wide Field Infrared Survey Explorer (NEOWISE), astronomers have created what is essentially...
Astronomers using the X-SHOOTER instrument at ESO’s Very Large Telescope (VLT) have detected light from a gamma-ray burst at a redshift of 6.3, meaning...
The very first stars likely formed when the Universe was only 100 million years old. Known as Population III stars, these stellar objects were so massive...
The newly-discovered blue supergiant is much hotter than the Sun, and existed when the Universe was about 2.6 billion years old.
Left panel shows the color...
Astronomers from the University of Cambridge and elsewhere have analyzed the spectroscopic and photometric data from three instruments (NIRSpec, NIRISS...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted ancient globular clusters around a remarkable galaxy that is strongly gravitationally...
Earendel emitted its light approximately 900 million years after the Big Bang.
This Webb/NIRCam image shows Earendel (center), the most distant star ever...
About 30% of short gamma-ray bursts (sGRBs), which form during the collisions of neutron stars, lack a coincident host galaxy, raising questions about...
Neutrinos are the most elusive particles in the Universe, capable of traveling nearly unimpeded across it. Despite the vast amount of data collected, a...
Known as Webb’s First Deep Field, the new image shows the massive galaxy cluster SMACS J0723.3-7327.
This Webb image shows the galaxy cluster SMACS J0723.3-7327....
On July 4, 2012, physicists from the ATLAS and CMS collaborations at CERN’s Large Hadron Collider announced the observation of a Higgs boson at a mass...
