JWST hints at atmosphere on earth-sized TRAPPIST-1e
The James Webb Space Telescope may have detected signs of a secondary atmosphere on TRAPPIST-1e, an Earth-sized exoplanet 40 light-years away. Tidally locked in its star's habitable zone, the planet could potentially support liquid water. Scientists caution that habitability isn't confirmed yet, but these findings make TRAPPIST-1e a top target in the search for life beyond Earth.
