Above a certain threshold, galaxies stop growing , no matter how much raw material they have on hand. The question is: what flips the switch?

The Magellanic Clouds are a pair of dwarf galaxies passing the Milky Way probably for the first time, but as they move they have been interacting with each other for billions of years.

A stunning spiral galaxy called Messier 88 is racing through the crowded Virgo Cluster on a journey that will dramatically reshape its future. At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful spiral arms sparkle with young star clusters and dark clouds of dust. But as M88 plunges deeper into the cluster over the next few hundred million y…

New observations from DECam reveal an enormous halo and evidence of an ancient galactic collision surrounding the iconic Sombrero Galaxy.

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

New simulations suggest a violent collision 11 billion years ago reshaped our Galaxy and triggered a burst of star formation. The post Violent Collision May Have Destroyed Milky Way’s First Stellar Disk appeared first on Sci.News: Breaking Science News .

A new study suggests that most "post-starburst galaxies" cease star formation because they run out of fuel. But that's not the full story.

New research reveals the sun’s astonishing journey from the galactic core, offering fresh insights into the evolution of the Milky Way and the conditions for life on Earth.
