Dimethyl sulfide is in the news after NASA’s James Webb Space Telescope may have detected relatively high levels of it in the atmosphere of an exoplanet called K2-18 b ...

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 ...

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 ...

A chemical called dimethyl sulfide popped up in an analysis of exoplanet K2-18b’s atmosphere. On Earth, it’s only made by living organisms.

Dimethyl sulfide is the largest natural source of atmospheric sulfur on Earth, which means that it gets into the atmosphere and cycles around. But it starts its journey in the ocean.

Dimethyl sulfide is cool—and a potential biosignature—but scientists are urging caution before we declare a plankton party some 120 light-years away.

The team announced this possible detection of dimethyl sulfide in 2023, but when other scientists followed up, it didn't pan out. "That was weak from the beginning," says Holmberg, ...

K2-18b was already known to contain water vapor and the newly found presence of dimethyl sulfide indicated to researchers something they first predicted in 2021 — that K2-18b is a “Hycean ...

By analyzing data from NASA and the European Space Agency's Webb Space Telescope, the researchers found evidence of dimethyl sulfide and dimethyl disulfide in the atmosphere of the planet known as ...
