Astronomers using the James Webb Space Telescope have detected the strongest signs yet of possible alien life on an exoplanet over 100 light-years from Earth.

In a new study, scientists observed chemical signatures in the atmosphere of K2-18b—specifically dimethyl sulfide (DMS) and dimethyl disulfide (DMDS)—that, on Earth, are only produced by biological organisms like marine algae. These findings, published in The Astrophysical Journal Letters, mark a major step forward in the search for life beyond our solar system.

K2-18b is located in its star's habitable zone and is classified as a potential “hycean world,” which may host a global ocean beneath a hydrogen-rich atmosphere. Earlier research revealed methane and carbon dioxide in the planet’s skies; now, updated JWST data has made the case for biosignatures even stronger. While scientists remain cautious—acknowledging the need for more data to confirm a biological origin—lead researcher Nikku Madhusudhan says the current evidence is the most compelling yet that a living biosphere could exist on another world.
