Astronomers using the Hubble Space Telescope have been studying the movement of the Milky Way and Andromeda galaxy for years and are predicting a direct hit. So how much time do we have before the collision? Only about 4 billion years.

We survived last year's end of the world prediction from Harold Camping, and hope to make it past the end of the Mayan Calendar on December 21. Does that mean the galaxy car-wreck will signal our demise?

"This is pretty violent as things go in the universe. It's like a bad car crash in galaxy-land." According to Astronomer Roeland van der Marel.

Our sun and the Earth are unlikely to be hit by stars or planets from Andromeda, however, because of the vast emptiness of both galaxies our planet should easily survive the merger. It's kind of like Paris Hilton and Kim Kardashian banging heads. It will take about two billion years for the Milky-Andromafication of our galaxies to complete and will drastically change the view of our nighttime sky.
