Best view yet of planet in hotly pursued star system
The exoplanet TRAPPIST-1b — one of seven roughly Earth-sized planets in the TRAPPIST-1 system — probably doesn’t have an atmosphere. It’s not surprising: TRAPPIST-1b is the closest to its star and is blasted by four times as much radiation as Earth receives from the Sun. But the work shows the transformational power of the James Webb Space Telescope (JWST) to observe the system, which offers a unique laboratory for studying planetary environments and how they might become suitable for life.
