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...
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...
About 30% of short gamma-ray bursts (sGRBs), which form during the collisions of neutron stars, lack a coincident host galaxy, raising questions about...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed a significant amount of cold, neutral gas in the outer regions...
Astronomers from the 3D-Drift And SHift (3D-DASH) program have released the largest near-infrared image ever taken by the NASA/ESA Hubble Space Telescope.
