A group of scientists using the James Webb Space Telescope has recorded the strongest signs of life on an alien planet, K2-18 b, by detecting gases—dimethyl sulfide (DMS) and dimethyl disulfide (DMDS)—associated with biological processes on Earth. While these findings suggest the potential for microbial life, researchers caution that they are not confirming the existence of living organisms but rather identifying a possible biosignature. Astrophysicist Nikku Madhusudhan emphasizes that this marks a transformational moment in the search for extraterrestrial life, highlighting the need for further observations to validate these discoveries.
