Colliding Galaxies

Two Galaxies Unable to Avoid Each Other

It takes hundreds of millions of years for the whole galaxy collision to complete. So, it's not like a car accident or anything of the sort. Phew, guess I wouldn't be moving galaxy anytime soon. Because I saw on the History Channel that our Milky Way is actually on a collision course with a smaller galaxy. Since our galaxy is so big and the process is so slow, our solar system is safe, right? Right?!

Apparently galaxy collision or merging galaxies is not uncommon. It was even more common when the universe was smaller and galaxies were closer together.
