TRAPPIST-1 d ruled out as Earth twin by Webb study
Paris, France (SPX) Aug 15, 2025 Astronomers have determined that TRAPPIST-1 d, a rocky exoplanet similar in size to Earth and located in a potentially temperate zone, lacks an Earth-like atmosphere based on new NASA/ESA/CSA James Webb Space Telescope data. The finding narrows the search for worlds with conditions similar to Earth, according to lead author Caroline Piaulet-Ghorayeb of the University of Chicago and Universite de Montreal's Trottier Institute for Research on Exoplanets. Webb's NIRSpec instrument found no signs of w ... read more |

James Webb reveals sub-Saturn mass exoplanet in young star system
Paris, France (SPX) Jul 11, 2025 The James Webb Space Telescope (JWST) has directly imaged a previously unknown exoplanet, marking a significant milestone since the telescope's launch in 2022. Led by a CNRS researcher at the Observatoire de Paris-PSL and Universite Grenoble Alpes, the discovery was enabled by a coronagraph developed in France and installed on JWST's MIRI instrument. This technology, created through a CNRS-CEA collaboration, functions by masking a star's light to reveal nearby, dimmer objects-similar to what occur ... read more
