Andromeda XXXV is only about 20,000 times more massive than our Sun—very small, even for a satellite galaxy. For comparison, the Milky Way’s mass is about 1.5 trillion solar masses, and the beefiest ...

An curved arrow pointing right. In 3.75 billion years, Earth's Milky Way Galaxy will collide with the Andromeda Galaxy. Over the next several billion years, the two galaxies will rip each other ...

The Milky Way has a 50-50 chance of colliding with a nearby galaxy in the next 10 billion years, a new study finds. Yet while those odds appear daunting, the new finding suggests the catastrophic ...

This offers forensic clues as to how our Milky Way galaxy and Andromeda have evolved differently over billions of years. Our Milky Way has been relatively placid. But it looks like Andromeda has ...

Situated approximately 2.5 million light-years from Earth, the Andromeda Galaxy is the closest major galaxy to the Milky Way, belonging to the Local Group cluster. It is a barred spiral galaxy ...

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 ...

Right now, the Andromeda galaxy is racing toward the Milky Way at a speed of 250,000 mph - fast enough to circle the world in just six minutes. And it's scheduled to collide, head-on, with the ...

Astronomers at the University of Michigan have discovered a new satellite of the Andromeda Galaxy (M31), the Milky Way’s closest major galactic neighbor, and it has broken the record for the ...
