Astronomers have detected helium escaping from LHS 1140 b, a rocky super-Earth orbiting within the habitable zone of a small red star about 48 light-years away. The signal is the first clear evidence of an atmosphere around a rocky planet in the habitable zone of another star. The finding, reported on 16 July in Science [...] The post For years astronomers kept finding rocky planets in habitable zones and then discovering they were bare, airless cinders.
