Hubble Observes Atmospheres of TRAPPIST-1 Exoplanets in the Habitable Zone

The Trappist-1 system, located 40 light-years away, contains seven Earth-sized planets, three of which are in the habitable zone. Hubble observations suggest these planets lack thick hydrogen-rich atmospheres, indicating they may be rocky. Future telescopes, including the James Webb Space Telescope, aim to further study these planets' atmospheres and potential habitability. The Trappist-1 system offers a unique opportunity to understand terrestrial exoplanets.
