On Earth, dimethyl sulfide is produced overwhelmingly by life in the oceans and escapes into the atmosphere. JWST has now picked up a tantalising possible signature of the same molecule around K2-18 b, 120 light-years away — but the detection remains disputed, and scientists are still trying to determine whether non-biological chemistry could produce it.
