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.

Black holes are demolishing thousands of stars in a quest to pack on weight, according to an analysis of images of 108 galaxies taken by NASA’s Chandra...
Astronomers using the NASA/ESA Hubble Space Telescope have spotted GNz7q, a black hole that existed only 750 million years after the Big Bang, in one of...
The newly-discovered galaxy, named HD1, existed when the Universe was just 330 million years old.

Designated WHL0137-LS and nicknamed Earendel, the newly-detected star emitted its light around 900 million years after the Big Bang.
Earendel (arrow) is...
The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question...
Each of the two newly-discovered protoclusters, MAGAZ3NE J095924+022537 and MAGAZ3NE J100028+023349 (MAGAZ3NE J0959 and MAGAZ3NE J1000 for short), hosts...

Fluorine is one of the most interesting elements for nuclear and stellar astrophysics. Fluorine abundance was first measured for stars other than the Sun...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected water and carbon monoxide molecules in a larger member of SPT-S...
The newly-discovered protocluster, named PHz G237.01+42.50 (G237 for short), contains over 60 members, including blue star-forming galaxies and active...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered two heavily dust-obscured star-forming galaxies — REBELS-12-2...
Massive galaxies in the early Universe should have contained large amounts of cold molecular gas, the fuel required to make stars. But new observations...
By combining gravitational lensing with the capabilities of NASA’s Chandra X-ray Observatory, astronomers have detected two X-ray-emitting objects —...
A team of astronomers from the United Kingdom and the United States has examined six of the most distant galaxies currently known and found that the distance...
Astrophysical observations show that supermassive black holes exist when the Universe is just 800 million years old after the Big Bang (just 6% of its...
