JWST hints at a mysterious molecule on Pluto and Titan, unseen elsewhere

A James Webb Space Telescope analysis of Pluto and Saturn’s moon Titan reveals a shared absorption feature near 5.11 micrometers, suggesting an unknown molecule may exist on both worlds. The suspected candidates include benzene or other hydrocarbons, but the exact identifications are unconfirmed and the study has not yet been peer‑reviewed. Researchers say this puzzling signal could be clarified by future observations, including NASA’s Dragonfly mission to Titan, which could help determine whether the molecule is viable on Pluto as well.
