The biosignatures were rooted in tentative detections, and this sparked debate amongst astronomers, who were skeptical about the data reliability.

Facebook X Reddit Email Dimethyl sulfide, also known as DMS, sounds like it could be a chemical compound you'd try to avoid on an ingredient label, or the poisonous ingredient in a murder mystery ...

A team of researchers has recently claimed they have discovered a gas called dimethyl sulfide (DMS) in the atmosphere of K2-18b, a planet orbiting a distant star.

On Earth, DMS in the atmosphere is produced by marine plankton, and the Cambridge team says the compound has been considered a ‘robust biosignature’ for planets like K2-18b, which is thought to have ...

On Earth, dimethyl sulfide is most often created by phytoplankton and other marine microbes. K2-18b is thought to harbor a huge 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 found that this weak signal matched a gas called dimethyl sulfide, or DMS. On Earth, DMS is produced in large quantities by marine algae. It has very few, if any, nonbiological sources.

The team's findings, based on their analysis of James Webb Space Telescope (JWST) data, point to an abundance of dimethyl sulfide (DMS) molecules in the atmosphere of a planet known as K2-18b ...

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 disulfide ...

But Schwieterman said that first, scientists need to confirm that dimethyl sulfide is really present in the atmosphere of K2-18b, which will require validation from multiple independent groups who ...
