SMRTR summary
For the first time, astronomers have detected an atmosphere around a rocky exoplanet in its star's habitable zone. The planet, LHS 1140 b, sits about 48 light-years away and is 5.6 times Earth's mass. Using a specialized spectrograph, scientists found helium escaping into space. Vast oceans may exist on its surface, but further observations are needed to confirm signs of life.
