40 light-years away lies the exoplanet GJ 1214b, a searingly hot super-Earth orbiting a red dwarf star. And thanks to the Hubble telescope, researchers believe theyve found what lies in the planets upper atmosphere: thick clouds. A paper, published in the January 2nd issue of Nature, relies on the telescope to settle a debate about the planets composition. First documented in 2009, GJ 1214b is one of several exoplanets that researchers are studying in hopes of finding a habitable world in another solar system.
