Webb Detects Possible Biosignature Gases in Atmosphere of K2-18b

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) in the atmosphere of the super-Earth exoplanet K2-18b. On Earth, DMS and DMDS are only produced by life, primarily microbial life such as marine phytoplankton. While an unknown chemical process may be the source of these molecules in K2-18b’s atmosphere, the results are the strongest evidence yet that life may exist on an extrasolar planet.

K2-18 is a red dwarf located approximately 111 light-years away in the constellation of Leo.

Also known as EPIC 201912552, the star hosts two massive exoplanets: K2-18b and K2-18c.

First discovered in 2015, K2-18b has a radius of 2.6 times that of Earth and is about 8.6 times as massive.

The planet orbits its star every 33 days at a distance of approximately 0.15 AU and has an Earth Similarity Index of 0.73.

It receives 1.28 times the light intensity of Earth, and its equilibrium temperature is minus 2 degrees Celsius (28 degrees Fahrenheit).

Earlier observations of K2-18b identified methane and carbon dioxide in its atmosphere. This was the first time that carbon-based molecules were discovered in the atmosphere of an exoplanet in the habitable zone.

Those results were consistent with predictions for a Hycean world: a habitable ocean-covered exoplanet underneath a hydrogen-rich atmosphere.
