First atmosphere detected on a habitable-zone rocky exoplanet (LHS 1140 b)
Key Questions
Why is the atmosphere detection on LHS 1140 b important?
It marks the first atmosphere detected on a rocky habitable-zone exoplanet, validating theoretical predictions for terrestrial worlds around M dwarfs. The finding opens new avenues for studying potential habitability.
How was the atmosphere on LHS 1140 b detected?
Ground-based spectroscopy revealed helium escaping from the planet, confirming the presence of an atmosphere. This is the first such detection for a rocky habitable-zone world.
What role will JWST play in studying LHS 1140 b?
JWST follow-up observations will be essential for detailed characterization of the planet's atmosphere and surface conditions. These data will help assess its potential habitability.
