Astronomers at the University of Michigan have discovered a new satellite of the Andromeda Galaxy (M31), the Milky Way's ...

Andromeda XXXV is only about 20,000 times more massive than our Sun—very small, even for a satellite galaxy. For comparison, ...

A team of astronomers recently uncovered an exceptionally small and faint dwarf galaxy located approximately 3 million ...

Deep observations from the James Webb Space Telescope (JWST) have revealed an exceptionally large galaxy in the early ...

A Swarm of Dwarf Galaxies Buzz Around Our Milky Way's Twin Imagine the Milky Way and Andromeda as two massive aircraft ...

The cosmos has a way of keeping astronomers on their toes. Just beyond the edges of the Andromeda galaxy, researchers have identified the tiniest galaxy ever ...

There is a supermassive black hole at the center of nearly every big galaxy—including ours, the Milky Way (it's called ...

A discovery made by a team led by researchers at the University of Michigan tugs at the seams of some key cosmic lessons we ...

However, our own Milky Way is on a path to collide with its giant neighbor, the Andromeda Galaxy. The next galactic merger of roughly 250 billion stars moving through space at high speed will change ...

Astronomers suspect Andromeda had a major collision with another galaxy relatively recently, perhaps 2 to 5 billion years ago. The Milky Way, on the other hand, probably hasn't had a run-in with ...

This task is somewhat less challenging around the closest major galaxy to the Milky Way, Andromeda. Other dwarf galaxies have been spotted around Andromeda before, but these have been large and ...

The Andromeda galaxy, seen here by NASA’s Spitzer space telescope, is the closest large galaxy to the Milky Way — but it seems to have evolved in a much different way, new Hubble data suggests.
