10 Remarkable Exoplanets


GJ 1214b

Liquid water would be perhaps the strongest sign that a planet could support life, and super-Earth GJ 1214b might have it in spades. In fact, astronomers think the planet might be one giant, deep ocean. Though in this case, the ocean might be too warm for it to support life.

Besides potentially having a watery surface, the planet is interesting for another reason. GJ 1214b is located a relatively close 41 light-years from Earth and orbits its star in a way that affords us a better view [source: Keim]. Why is this important? Both of these conditions make GJ 1214b ideal for observation. As the precision of our instruments improve, we should be able to learn some incredible information about the planet's atmosphere and composition, and, by extension, the nature of other solar systems.
