"Ah Crap. Something Bad To Think About"

"Four billion years from now, the Milky Way galaxy as we know it will cease to exist.
Our Milky Way is bound for a head-on collision with the similar-sized Andromeda galaxy, researchers announced today (May 31). 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".
