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 ...

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.

According to Madhusudhan and his team, one of the molecules that K2-18b’s atmosphere contained was dimethyl sulfide. On Earth, dimethyl sulfide is produced only by living organisms, and not just ...

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 ...

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 ...

In 2023, the team reported tentative signs of a molecule called dimethyl sulfide, a possible biosignature, in K2 18b’s atmosphere. In April 2024, they looked again with a third JWST instrument.

According to research led by the University of Cambridge, the team detected traces of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in the planet’s atmosphere. On Earth, these compounds ...

They have picked up the chemical fingerprints of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) – molecules that are primarily produced by microbial life such as marine phytoplankton.

K2-18b — which is eight times the size of Earth and 124 light-years away — shows signs of the unique molecule dimethyl sulfide, according to a new study published in the Astrophysical Journal ...

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.
