Milky Way Doomed to Crash with Andromeda
Four billion years from now, the Milky Way galaxy as we know it will cease to exist.

Over time, the huge galactic smashup will create an entirely new hybrid galaxy, one likely bearing an elliptical shape rather than the Milky Way’s trademark spiral-armed disk.
