First atmosphere found on Earth-like planet in habitable zone of distant star
Astronomers have detected an atmosphere on LHS 1140 b, a rocky, Earth-like planet located in the habitable zone of a distant star. While the atmosphere currently shows signs of helium rather than life-sustaining gases, it marks a major milestone in the search for habitable worlds.
Why it matters
This is the first time an atmosphere has been confirmed on a rocky planet in a habitable zone, significantly advancing the search for extraterrestrial life.
