Mergers and Acquistions

This animation depicts the predicted collision between our galaxy (The Milky Way) and our larger neighbor, the Andromeda galaxy. The two are being pulled together by their mutual gravity, and will crash together about 4 billion years from now. Later, around 6 billion years from now, the two galaxies will merge. The video also shows a third galaxy (the Triangulum) which will join in the pill up and may wind up merging with the Andromeda/Milky Way pair.
