What Is Dimethyl Sulfide? 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 work, announced Wednesday, builds on previous observations from JWST published in 2023 by the same team that yielded weak hintsContinue reading "K2-18 b could have dimethyl sulfide in its air.

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. But some scientists ...

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 ...

Scientists have detected dimethyl sulfide, a chemical linked to life on Earth, in the atmosphere of exoplanet K2-18b. Could this be a sign of alien life?

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

Intriguingly, they also saw hints of dimethyl sulfide. This sulfur-based molecule is seen as a potential indicator of life because on Earth, it's only made by living things such as ocean ...

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 ...

Madhusudhan and his team reported taking atmospheric measurements of the dimethyl sulfide on K2-18b back in 2023 — and confirmed the molecule’s overwhelming presence in tests conducted last ...

Fresh data from the James Webb Space Telescope provide more evidence for what some consider a biosignature — but debate is sure to follow.

Both dimethyl sulfide and dimethyl disulfide, which are part of the same chemical group, have overlapping characteristics, which is why the results can’t definitively differentiate between the ...
