New data from JWST shows TRAPPIST-1b may have an atmosphere after all.

The Earth -sized planet orbiting a red dwarf some 40 light-years away may have a thick carbon dioxide atmosphere.

The planet is too close to its star to be habitable, but astronomers hope it can teach us about how other planetary systems form and evolve.
