NASA's Hubble Sees Cloudy Super-Worlds With Chance for More Clouds
The planets are GJ 436b, located 36 light-years from Earth in the constellation Leo, and GJ 1214b, 40 light-years away in the constellation Ophiuchus. Despite numerous efforts, the nature of the atmospheres surrounding these planets had eluded definitive characterization until now. The researchers described their work as an important milestone on the road to characterizing potentially habitable, Earth-like worlds beyond the solar system. Their findings appear in separate papers in the Jan. 2 issue of the journal Nature.
