Galactic Collisions
In the previous blog "Galaxies" we saw about the types of galaxies, active galaxies and that the Andromeda galaxy will collide with the Milky Way galaxy. The collision is inevitable but won't happen now as it may take several billion years. When the collision occurs both galaxies may pass each other the first time, but in the next few hundred million years it will bounce back and collide that may form one bigger galaxy probably an elliptical galaxies which astronomers call the "Milkomeda". During the collision the sun may go farther into the galactic suburbs or further into the galaxy. It may still orbit around the new center of Milkomeda and earth may still exist, that is if it survives for a few billion years. Fact: It is believed that elliptical galaxies are formed due to Galactic Collisions. It is less likely that two stars will collide when the galaxies merge, as they a have a lot ...
