MEGATRON simulations suggest the Milky Way formed through the collisions and mergers of thousands of small galaxies in the ...

A new supercomputer simulation traces how thousands of small galaxies eventually became the Milky Way.

Long before it became the luminous spiral galaxy we call home, the Milky Way was a sprawling, chaotic swarm of thousands of ...

The discovery offers fresh clues about cosmic evolution when the universe was barely a billion years old. However, these ...

The Sombrero Galaxy (Messier 104) contains a supermassive black hole within an immense central bulge of stars. Around its prominent dust lanes, Chandra maps a diffuse halo of million-degree gas and a ...

Cambridge, MA (September 14, 2026) —A new study of nine nearby galaxies has shown that actively growing supermassive black holes may contribute to star formation, instead preventing star formation, in ...

12.5 billion light-years away, a galaxy existed before Earth, before our solar system, before almost everything we know — and deep inside it, three supermassive black holes are locked in a ...

This artist’s concept depicts a tidal disruption event, which occurs when a star passes fatally close to a supermassive black hole. Crumbs of the splintering star heat up as they swirl around the ...
