Milky Way Collision With Andromeda Galaxy

NASA scientists announced that after scouring reams of data from the Hubble Space Telescope they can say with certainty that our Milky Way is destined to eventually collide with our neighbour the Andromeda galaxy. Of course, it won’t happen for about 4 billion years
Andromeda is currently 2.5 million light-years from Earth, but moving at a pretty swift 250,000 miles per hour. At that speed, the collision won’t be happening until about 4 billion years from now. NASA says that their data suggests that Andromeda’s tangential — or “sideways” — motion is such that the Milky Way will experience a head-on collision from the neighboring galaxy.
