What the Andromeda and Milky Way collision will look like

Prepare the bunker, Earthlings. In T-minus 4 billion, our neighboring Andromeda galaxy will collide with our own Milky Way. Scientific American’s Caleb Scharf offers a preview of the space fireworks we can expect.

In about 4 billion years these two galaxies will begin a ponderous collision lasting for perhaps 100 million years or so. It will be a soft type of collision – individual stars are so tiny compared to the distances between them that they themselves are unlikely to collide, but the great masses of gas and dust in the two galaxies will smack together – triggering the formation of new stars and planetary systems.

Via Scientific American.

A trip to space.
