With the James Webb Space Telescope’s ability to detect and study the atmospheres of distant planets orbiting other stars, exoplanet enthusiasts have been anticipating JWST’s first data on some of the worlds in the famous TRAPPIST-1 system. This is the system where seven Earth-sized worlds are orbiting a red dwarf star, with several in the habitable zone.
Today, a new study was released on the innermost planet in the system, TRAPPIST-1 b. The authors of the study were quite frank: this world very likely has no atmosphere at all. Additionally, the conditions there for possible life as we know it only get worse from there.
