What do you get when the Andromeda Galaxy and our own Milky Way Galaxy collide? The Milkdromeda Galaxy, of course.
Why It Matters
- Every star that we can see with our eyes is in the Milky Way Galaxy.
- A blur in the sky is an entirely different spiral galaxy, the closest galaxy to us, Andromeda.
- Both galaxies have 100 billion or more stars.
- The estimates for the time when the collision between the two galaxies will occur are very different.
