Keep your specs on and stock up on water and canned goods, because the Milky Way, that thing we've been blasting with a laser, is going to collide with the Andromeda galaxy. Well, in about 4 billion years, but it's never too late to be prepared.

According to astronomer Zachory Berta, "GJ1214b is like no planet we know of." That's because a "huge fraction" of the planet is made up of water — a concept that's hard to drink in when one considers the fact that GJ1214b is a scant 1.3 million miles from its native star and boils at 450 ° Fahrenheit. It's unlike any other planet Hubble has spied to date.
