Dimethyl sulfide (DMS), emitted from the oceans, is the most abundant biological source of sulfur to the marine atmosphere. Atmospheric DMS is oxidized to condensable products that form secondary ...

Scientists have reported new observations from NASA's James Webb Space Telescope (JWST) that strengthen the case that the exoplanet K2-18 b has molecules in its atmosphere that, on Earth, are produced ...

A team of astronomers have detected what they call the most promising signs to date of a possible biosignature, or signs of past or present life linked to biological activity, on an exoplanet named K2 ...

A team of astronomers announced this week that they’ve detected a possible sign of life on an exoplanet 124 light years away using the James Webb Space Telescope. Even more enticingly, the exoplanet, ...

Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate. Modelling studies have long suggested that the ...

An artist's concept shows what K2-18b might look like. Thought to be covered entirely in liquid water with a hydrogen-rich atmosphere, the exoplanet may be a good place to look for biological activity ...

“This is sooooooooo exciting. Could go away with more data but it’s exactly the kind of path we’d expect on the road [to] finding life,” wrote astrophysicist Adam Frank of the University of Rochester.

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." The saga surrounding Neptune-size "super-Earth" exoplanet K2-18 b ...

New James Webb Space Telescope (JWST) observations provide strengthened evidence for the presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in the atmosphere of exoplanet K2-18 b, ...
