The presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in K2-18b’s atmosphere is controversial because these molecules—which on Earth are produced by phytoplankton and bacteria, respectively—can also be formed in lifeless environments, and the detection’s statistical significance “is at the lower end of robustness typically required for scientific evidence,” as noted by the researchers who found the presence of DMS and DMDS in K2-18b’s atmosphere.
