Astronomers are closer than ever to working out how the biggest galaxies in the cosmos grew so quickly before dying.

A galaxy collision in Stephan’s Quintet has created a powerful shockwave, providing vital data on galactic evolution.

An in-depth study of this image revealed that the two galaxies may have interacted in an intense collision, allowing the larger NGC 4694 to steal gas from the smaller VCC 2062. This dramatic ...

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".
