Milky Way Destined for Head-On Collision

The U.S. space agency, NASA, says our galaxy, the Milky Way, and the neighboring Andromeda galaxy will crash into each other in 4 billion years in a head-on collision.

NASA scientists say the new findings end nearly 100 years of speculation about whether Andromeda would directly plow into our galaxy, or merely deliver a glancing blow as it continued moving through the cosmos.

The study co-authors say the Earth and the other seven planets in the solar system likely will not be destroyed in the titanic pile-up, but the Sun - just like many other stars - will be flung into a different part of the galaxy. In all likelihood, the Sun will complete its stellar life-cycle in an area even farther away from the galactic core than it is now.
