Milky Way Destined for Head-On Collision

News for astronomy lovers and hobbyists!! Our Milky Way is 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.

The NASA scientists say their findings indicate that Andromeda and the Milky Way will take about 2 billion years to completely merge into a single elliptical-shaped galaxy.
