From the space.com report. "Astronomers have analyzed the distant Earth-like planet TRAPPIST-1e to develop a framework that will help scientists determine if any planets outside the solar system could harbor life or could be fit for human habitation. TRAPPIST-1e is one of seven worlds in the Trappist-1 system orbiting a relatively cool M-dwarf star located 39 light-years from Earth. The fact that all of these extrasolar planets — or exoplanets — are thought to be rocky or terrestrial worlds that are of similar sizes to Earth has made the TRAPPIST-1 system a primary focus for the search for life elsewhere in the universe. Over the coming year, the system and TRAPPIST-1e — considered one of the most 'potentially habitable' exoplanets ever discovered — in particular, will be the subject of intense study by the James Webb Space Telescope (JWST)."
This is important. So far, there is apparently no direct detection of atmospheres in the TRAPPIST-1 exoplanets as seen at this site, Exoplanet atmospheres (iac.es)
and ability to identify specific molecules in their atmospheres.
