Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity ...

The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, chaotic bundles of turbulent gas, churned up by huge gulps of intergalactic gas, ...

Using the James Webb Space Telescope, astronomers have investigated 70 dusty galaxies at the very edge of the universe that challenge our understanding of cosmic evolution.
