JWST Detects DMS/DMDS Signatures in K2-18b's Atmosphere, a Strong Biosignature Hint for an Exoplanet
To the point
Led by Nikku Madhusudhan, researchers using JWST's MIRI detected signatures of dimethyl sulfide and possibly dimethyl disulfide in the atmosphere of the Hycean exoplanet K2-18b, offering the strongest biosignature hint yet but requiring more observations to rule out non-biological production.
