11 Fascinating Facts About Our Milky Way Galaxy.
08- The Milky Way is going to crash with its neighbor in 4 billion years.

Sad to say, but our galaxy isn't going to be here forever. Astronomers know that we are currently speeding toward our neighbor, the Andromeda galaxy, at around 250,000 mph (400,000 km/h). When the crash comes, in about 4 billion years, most research has suggested that the more massive Andromeda galaxy would swallow up our own and survive. But in a recent study, astronomers reweighed Andromeda and found that it was roughly equivalent to 800 billion suns, or about on par with the Milky Way's mass, as Live Science previously reported. That means that exactly which galaxy will emerge less scathed from the future galactic crash remains an open question.
