•Potentially habitable planet TRAPPIST-1b may have a carbon dioxide-rich atmosphere
76% Informative
TRAPPIST-1b, the innermost Earth -like planet in the famous TRAPPist-1 system, may have a thick carbon dioxide-rich atmosphere.
Previous observations suggested all planets in the system would be barren, airless rocks thanks to violent, atmosphere-stripping radiation unleashed by their host star.
But new data from the James Webb Space Telescope suggests that it may have an unexpectedly high temperature for the planet's surface, potentially indicating that the world is roiling with volcanic activity.
