Helium Escape on LHS 1140 b: First Direct Evidence of a Rocky Planet's Atmosphere in the Habitable Zone
To the point
Scientists, including Collin Cherubim and Shreyas Vissapragada of Harvard and Jason Dittmann of the University of Florida, have detected an atmosphere around the rocky, habitable-zone exoplanet LHS 1140 b by observing escaping helium, suggesting such worlds can retain atmospheres and may be common.
