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.
NASA's Kepler mission has been spoiling us with planetary discoveries left and right as of late. Now, researchers using NASA's Hubble Space Telescope have discovered an entirely new class of planet — they call it a "waterworld," and it might be covered in broiling-hot ice.
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.
Just 13 parsecs away, a planet astronomers are calling a "super Earth" is orbiting a dwarf star. Its radius is over twice that of Earth, and there's something very surprising in its core.
