According to a new study, some of the earliest galaxies observed with the James Webb Space Telescope are in fact much less massive than they first appeared. Black holes in some of these galaxies make ...

The cosmos may not be broken after all. Soon after the James Webb Space Telescope (JWST) started its science mission in 2022, astronomers discovered a half-dozen galaxies near the edge of the universe ...

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

Covering a huge area of the sky in three mosaics, the data release also includes numerous galaxy clusters, active galactic nuclei and transient phenomena, as well as the first classification survey of ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...

New radio observations of molecular gas reveal how dozens of galaxies could have rapidly merged together in the early Universe.

Head-scratching observations of distant galaxies are challenging cosmologists’ dominant ideas about the universe, potentially leading to the implication that the strange substance called dark matter ...

A new JWST study finds early galaxies at redshift 6–10 may be nearly as old as the universe at that time. One galaxy even appears older than cosmic age estimates, potentially challenging the standard ...

Researchers discovered a hidden 185,000 light-year "bridge" of gas between two distant galaxies, which are also trailed by a 1.6 million light-year galactic tail — the largest of its kind ever seen.
