Zachory Berta says that "GJ1214b is like no planet we know of." Like Berta, part of a team at the Harvard-Smithsonian Center for Astrophysics lead by David Charbonneau, his colleagues were surprised when they discovered that this planet is made mostly of water.
This is how I imagine GJ1214b, a super-Earth discovered only forty light-years away from us, orbiting a red dwarf star in the constellation of Ophiuchus. The good news: It's three parts water. The bad news: The beaches are too hot.
