As astronomers study an exoplanet called K2-18b, conflicting research reveals how difficult it is to find evidence of life beyond Earth.

The most noticeable features from a gas like dimethyl sulfide stem from a bond of hydrogen and carbon molecules — a connection that can stretch and bend and absorb light at different wavelengths ...

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 ...

Last month, astronomers using the James Webb Space Telescope made headlines by announcing they had detected hints of the chemicals dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) on the planet.

The group had analyzed readings taken by the James Webb Space Telescope, and concluded they confirmed the presence of either dimethyl sulfide or dimethyl disulfide—two molecules that, on Earth ...

Basically, what they found was a particular color in the atmosphere of this planet, K2-18b, that is produced by a molecule called dimethyl sulfide.

While dimethyl sulfide and dimethyl disulfide are formed on Earth exclusively by living organisms, it doesn't mean they cannot be made abiotically.

According to Space.com, the James Webb Space Telescope found indications of dimethyl sulfide in K2-18b’s atmosphere using two of its specialized instruments.
