James Webb Space Telescope discovers a hot Jupiter exoplanet leaking twin gas tails that defy explanation
Observations of a hot Jupiter exoplanet collected by the James Webb Space Telescope have revealed that it has twin tails of helium, defying current atmosphere escape models.
For the first time, the James Webb telescope provides detailed data on the atmospheric loss of the exoplanet WASP-121 b. across a complete orbit, a surprising structure of two gas tails has emerged. This calls into question previous models. (Read more)
James Webb telescope reveals spectacular atmospheric escape
Astronomers from the University of Geneva (UNIGE), the National Centre of Competence in Research PlanetS, and the Trottier Institute for Research on Exoplanets (IREx) at the University of Montreal (UdeM) have made a striking discovery using the James Webb Space Telescope (JWST). For the very first time, scientists have continuously monitored the atmosphere escaping from an exoplanet throughout a complete orbit. The result: the gas giant WASP-121…
