1st atmospheric study of Earth-like exoplanets
Astronomers used NASA's Hubble Space Telescope to conduct the first atmospheric study of Earth-like exoplanets and found that two such planets, 40 light-years away, could be habitable. The two exoplanets, which were discovered in May, are part of a three-planet system, all of which have sizes and temperatures similar to Venus and the Earth, and orbit a red dwarf star.
