The work, announced Wednesday, builds on previous observations from JWST published in 2023 by the same team that yielded weak hints of the molecule dimethyl sulfide (DMS) on K2-18 b, a planet that ...

In chemical terms, dimethyl sulfide comprises one atom of sulfur bonded to two methyl groups, each of which contains one carbon atom and three hydrogen atoms. The result is a small molecule with ...

Using the James Webb Space Telescope, the team detected chemical fingerprints within the atmosphere of K2-18b that suggest the presence of dimethyl sulfide or DMS, and potentially dimethyl ...
