Revisiting K2-18 b: JWST finds a lead in the search for life on a mysterious exoplanet

This week we revisit one of the most remarkable exoplanet discoveries of 2024 with the help of the James Webb Space Telescope (JWST). JWST detected signs of methane and carbon dioxide in the atmosphere of K2-18 b. Knicole Colón, the deputy project scientist for exoplanet science for JWST, explains how this discovery could reshape our search for life beyond Earth and teach us more about the enigmatic class of exoplanets known as sub-Neptunes. Stick around for What's Up with Bruce Betts, the chief scientist of The Planetary Society.
