Milky Way Galaxy to collide with Andromeda Galaxy

Sound collision alert!!! From Talking Points Memo:

Earth’s home, the Milky Way Galaxy, will collide with a nearby galaxy called Andromeda in 4 billion years, according to new observations made using NASA’s Hubble Space Telescope announced Thursday.

“Our findings are statistically consistent with a head-on collision between the Andromeda galaxy and our Milky Way galaxy,” said Roeland van der Marel of the Space Telescope Science Institute (STScI) in Baltimore, in a press release.

Andromeda, which is located 2.5 million light-years away, is moving rapidly towards the Milky Way at a rate of 250,000 milers-per-hour, a clip that will only increase as the galaxies approach.

The great galactic union isn’t expected to result in the destruction of Earth, the Sun, or any other planet in the solar system. In fact, no stars whatsoever are expected to collide becauase they are so far apart within each system.

But because the Milky Way is flatter than Andromeda, when the two spiral-shaped galaxies collide, they’ll form a single new elliptical-shaped galaxy that is more “three dimensional” in shape, with the merging complete 6 billion years from now.

During the course of the collision and merging, Earth’s Sun, and our entire solar system, will be flung from its current position to a new position on the outer edge of the new galaxy.

I guess we'll need to start building the "Noah's Ark" Rocket Ship;
