Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits within a "habitable zone," according to NASA. Astronomers say the planet, dubbed TOI-715 b, is about one and a half times the width of Earth and orbits a small, reddish star. The same system also might harbor a second, Earth-sized planet, which, if confirmed, "would become the smallest habitable-zone planet discovered by TESS [the Transiting Exoplanet Survey Satellite] so far," NASA said in a Jan. 31 press release.
