Some of TRAPPIST-1’s planets could have life-friendly atmospheres
One in particular looks a lot like Earth
PEERING THROUGH THE MIST Starlight filtering through the atmospheres of the planets orbiting TRAPPIST-1 (shown here in an artist’s illustration of the two innermost worlds) can give scientists a clue to the planets’ habitability. Scientists have now probed the atmospheres of the four middle planets, which could be well-suited for life.
