Potential Atmosphere Detected on Habitable-Zone Exoplanet LHS 1140b
Astronomers have detected evidence of a variable atmosphere on the exoplanet LHS 1140b, located in the habitable zone of a nearby star. Observations suggest the planet may lose and regain helium due to stellar radiation.
Why it matters
This discovery provides critical insights into whether rocky, Earth-like planets can retain atmospheres, a key factor in the search for extraterrestrial life.
Using spectral data from the Magellan Clay telescope at Las Campanas Observatory, astronomers detected helium escaping from LHS 1140b , a rocky exoplanet that orbits in the habitable zone of the nearby low-mass star LHS 1140.
