In A Nutshell Astronomers have identified 18 ancient, dust-shrouded galaxies from the universe’s first billion years that ...

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.

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

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 ...

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove ...

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.

Approximately 424 million light-years away, a vast chunk of the cosmic web (the network-like distribution of matter the universe displays on the largest scale) appears as if it’s been caught in a ...

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...
