JWST reveals TRAPPIST-1 b may have an atmosphere, challenging previous findings of barrenness.

Researchers using the James Webb Space Telescope (JWST) have found that TRAPPIST-1 b, an Earth-sized planet orbiting a red dwarf star, may not be as barren as previously thought. The study suggests the planet could have an atmosphere rich in carbon dioxide or a surface of unweathered rocks, challenging earlier findings that it had no atmosphere. The research highlights the complexity of studying exoplanets' atmospheres and calls for further investigation.
