Study Details What Happens When Galaxies Collide

Aspiring Astronomer writes: According to a recent study, when two galaxies of a similar mass collide, both galaxies will begin producing more stars. However, when one galaxy considerably outweighs the other, the larger galaxy begins producing more stars, whereas the smaller galaxy's star production begins to slow. This may be because the larger galaxy is able to draw gases from the smaller one, resulting in the formation of more stars. The Milky Way may experience a collision of it's own, because the Andromeda Galaxy is moving towards us at speeds upwards of 200,000 miles per hour. No need to worry, though; this collision is a few billion years away.
