Giant Exoplanet TOI-5205b Has Carbon-Rich, Oxygen-Poor Atmosphere, Webb Observations Show
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b, an extrasolar gas giant orbiting a small, dim red dwarf star. These observations have revealed an atmosphere unexpectedly poor in heavy elements, raising fresh questions about how such ‘forbidden’ alien worlds take shape and evolve. The…
