Astronomers use light signatures to determine the atmospheric gases of exoplanets, a key goal of the James Webb Space Telescope. Detecting biosignatures is challenging due to non-biological sources of molecules. A recent study detected dimethyl sulfide in exoplanet K2-18b's atmosphere, potentially from plankton. Evidence for life will accrue slowly, with ongoing debate leading to scientific consensus.
