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.

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 ...

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 ...

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 ...

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 ...

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.

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 ...

The main character here is dimethyl sulfide, a molecule produced by many ocean denizens, but especially plankton. If the molecule is really floating around in the atmosphere of K2-18b, it raises ...

In 2023, they reported they had also detected faint hints of another molecule, and one of huge potential importance: dimethyl sulfide, which is made of sulfur, carbon, and hydrogen. On Earth ...

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 ...
