First atmosphere found on Earth-like planet in habitable zone of distant star
Scientists have detected an atmosphere around LHS 1140 b, an Earth-like rocky planet orbiting in the habitable zone of a distant star 48 light-years away. Though helium was identified in the atmosphere, other gases potentially suitable for life may also be present. This discovery marks the first time an atmosphere has been found on a rocky planet in another star's habitable zone, bringing researchers closer to understanding whether life-supporting worlds exist beyond our solar system.
