Thanks to the James Webb Space Telescope (JWST), an international team of scientists from the Universities of Montreal, Chicago, and the Laboratoire de Météorologie Dynamique has just published the first observational constraints on the presence of an atmosphere around the exoplanet TRAPPIST-1d in The Astrophysical Journal. This is the first study of its kind conducted on a temperate planet within the famous TRAPPIST-1 system. More information is available in the CNRS press release:
