Planet GJ-1214b has a lot of water. But instead of oceans and lakes, its water is more likely in the form of steam and “hot ice.” Host Bruce Gellerman talks to Zachory Berta, a graduate student in astronomy at Harvard University. Along with a team of astronomers at the Harvard-Smithsonian Center for Astrophysics, Berta discovered and described this totally new type of planet.
