Here's Why So Many Massive Galaxies in the Early Universe Stop Forming Stars
The early Universe is full of massive galaxies that stopped forming stars very early. They're called massive quenchers (MQ) and they're challenging to explain. ...

Astronomers Uncover Statistical Evidence for Recoiling Supermassive Black Holes
Galactic collisions are events of breathtaking proportions. The Supermassive Black Holes (SMBHs) at their centers plunge into a chaotic orbital dance that event...
The light from the Andromeda Galaxy — the most distant object visible to the naked human eye — left its source about 2.5 million years ago, which means when you look at it on a clear night, you are se
On a clear, moonless autumn night, away from city lights, the patch of sky between the constellations Andromeda and Cassiopeia contains a faint, fuzzy smudge th...

How big can a galaxy get?
Deep surveys of the sky have turned up galaxies vastly larger than our own. Are there even bigger ones yet to be seen?
