Trappist-1 System Planet Lineup (Artist’s Concept)

So far, the science community has reported on their Webb observations for four of the seven TRAPPIST-1 planets: b, c, d, and e. Of the four planets, scientists have found little atmospheric evidence for TRAPPIST-1 b and TRAPPIST-1 c (white outlines). For TRAPPIST-1 d and TRAPPIST-1 e, the data is still under study (gray outlines), but scientists have ruled out the existence of thick hydrogen atmospheres. The community is still analyzing the Webb data on TRAPPIST-1 f, g, and h (dashed outlines).
