Astronomers have discovered over 100 new alien worlds so far this year — some many light-years away from Earth — that ...

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

While the molecules identified on K2-18b by the April study — dimethyl sulfide, or DMS, and dimethyl disulfide, or DMDS — are associated largely with microbial organisms on our planet ...

Dimethyl sulfide is the largest natural source of atmospheric sulfur on Earth, which means that it gets into the atmosphere and cycles around. But it starts its journey in the ocean.

The other two chemicals were diethyl sulfide and methylacrylonitrile, the latter of which is toxic. Dr Madhusudhan admitted that these little-known chemicals are likely not “realistic molecules ...

In this case, if the signature could be dimethyl sulfide or ethane—a molecule we've seen around planets in our own solar system—they assume the answer that's more common, not the most exciting.

In this case, if the signature could be dimethyl sulfide or ethane—a molecule we’ve seen around planets in our own solar system—they assume the answer that’s more common, not the most exciting. ‘We ...

This April, news reports linked the stinky gas dimethyl sulfide (DMS) in the atmosphere of a distant exoplanet called K2-18b to possible life on it. The reports, prompted by work led by astronomer ...

On Earth, dimethyl sulfide is associated with biology, in particular bacteria and plankton in the oceans. However, it can also arise by other means, so this single molecule is not conclusive proof ...

Avi Loeb, a Harvard professor of science and theoretical physicist, told NewsNation that while dimethyl sulfide and dimethyl disulfide appear to be present in the atmosphere of the planet K2-18b ...

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.
