New Results from the JWST Suggest that TRAPPIST-1e Might Have a Methane Atmosphere, Though Caution is Advised
An international team of astronomers has published a series of papers detailing their observations of the rocky exoplanet TRAPPIST-1e using the James Webb Space Telescope (JWST). Their results, though ambiguous, are a big step towards exoplanet characterization.
A red dwarf star, TRAPPIST-1, close to us at 40 light-years, produces powerful eruptions several times a day. Yet, it is home to seven Earth-sized planets, including...
TRAPPIST-1e Methane Signal Likely False, Webb Data Suggests Airless Planet
The TRAPPIST-1 planetary system, located about 39 light-years from Earth, hosts seven rocky worlds orbiting a cool red dwarf star. While several of these Earth-sized planets lie in the star’s habitable zone, new observations from the James Webb Space Telescope suggest their atmospheres may be too thin to support life. Earlier hints of methane around TRAPPIST-1e now appear to be background noise, strengthening the case that intense stellar radiat…
