First Atmosphere Discovered Around Earth-Like Planet LHS 1140b
Scientists have discovered the first confirmed atmosphere, composed of helium, on an Earth-like rocky planet called LHS 1140 b, which orbits within the habitable zone of a distant star 48 light-years away. While the helium atmosphere alone cannot support life, the finding provides strong evidence that planets similar to Earth may exist beyond our solar system, bringing scientists closer to potential life-supporting worlds. The planet's position in the habitable zone and its rocky nature are significant steps in the search for extraterrestrial life, although further research is needed to detect other gases that could support life.
