Helium Clue Reveals Atmosphere on Earth-Like Exoplanet in Habitable Zone
TL;DR Summary
Astronomers have found the strongest evidence yet that the rocky exoplanet LHS 1140 b, orbiting a red dwarf in its habitable zone, retains an atmosphere, inferred from helium escaping from the planet and detected with ground-based spectroscopy; the result suggests Earth-like worlds can maintain atmospheres for billions of years and opens new avenues to study their habitability.
