Neighboring Andromeda Galaxy to eat Milky Way in 5 billion years
Crawley, Australia (UPI) Sep 19, 2014
All galaxies grow by pulling in cosmic debris, gas and dust, and are rather efficient at converting it into new stars. But as galaxies age and grow more massive over time, their ability to create their own stars wanes, and they are forced to add on mass by swallowing up other smaller galaxies. A new study claims our own galaxy, the Milky Way, has already reached that tipping point - no longer able to produce our own fresh stars, we must resort cosmic cannibalism. It's a strategy that will even ... read more
