Earth’s dimethyl sulfide is constantly being produced by tiny plankton in the oceans. From there, it rises into the atmosphere, where it makes up about one out of every billion molecules.

In a groundbreaking discovery, astronomers have detected potential biosignatures, dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), in the atmosphere of exoplanet K2-18b using the James ...

Scientists have announced the detection of dimethyl sulfide—a chemical that, on Earth, is only produced by living organisms—in the atmosphere of an exoplanet called K2-18b. This is the second ...

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 ...

On Earth, that gas—called dimethyl sulfide—is mostly produced by living organisms. By comparing those fingerprints to 20 different molecules that they would potentially expect to observe in ...

Madhusudhan et al. just reported ~3 sigma detection of dimethyl sulfide (DMS) or dimethyl disulfide (DMDS) in the atmosphere of K2-18 b in the Astrophysical Journal Letters. The claim is intriguing, ...

Astronomers have detected unusual molecules, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), in the atmosphere of exoplanet K2-18b using the James Webb Space Telescope. As these molecules are ...

Atmospheric analysis of K2-18b, a planet a bit smaller than Neptune, has revealed two biologically produced compounds from the same chemical family, dimethyl sulfide and dimethyl disulfide.
