JWST Hints of Potential Biosignature Molecules on Exoplanet K2-18b, but Evidence Is Not Conclusive
To the point
Webb's observations of the exoplanet K2-18b hint at the presence of molecules associated with life on Earth, such as dimethyl sulfide and possibly dimethyl disulfide, but scientists including Nahum Arav caution that the evidence is not conclusive and must be independently verified with further observations to rule out nonbiological explanations.
