Scientists: Milky Way Galaxy to Crash into Andromeda Galaxy— But Earth to Survive
Yahoo! News— Don’t worry about when the world as we know it might end. NASA has calculated that our entire Milky Way galaxy will crash into a neighboring galaxy with a direct head-on hit — in 4 billion years.
Astronomers in a NASA news conference Thursday said that years of observations from the Hubble Space Telescope provide grisly details of a long-anticipated galactic smashup. Astronomers had seen the Andromeda galaxy coming at us, but thought there was a chance that its sideways motion would make it miss or graze the Milky Way. Hubble readings now indicate that’s not the case.
“This is pretty violent as things go in the universe,” said Roeland van der Marel, an astronomer with the Space Telescope Science Institute in Baltimore that operates Hubble. “It’s like a bad car crash in galaxy-land.”
