== Habitability ==
In September 2023, NASA announced that observations by the James Webb Space Telescope revealed the presence of methane, carbon dioxide, and possibly dimethyl sulphide (DMS) in the planet's atmosphere. The presence of DMS is a potential biosignature, as the bulk of the DMS in Earth's atmosphere is emitted from phytoplankton in marine environments, although further observation to confirm the presence of DMS and rule out a geological or chemical origin for the compound is required.
