What Webb Is Revealing About the TRAPPIST-1 Rocky Worlds
Located 40 light-years away, the TRAPPIST-1 system contains seven Earth-sized rocky worlds orbiting an ultra-cool red dwarf star. NASA's James Webb Space Telescope is probing their atmospheric presence and composition. Early data shows planets b and c lack thick atmospheres, while d and e do not possess thick hydrogen envelopes, as researchers untangle planetary signals from severe stellar flaring.
