Strongest Evidence Yet of Possible Alien Life Found: James Webb Telescope Detects Life-Linked Gases on Distant Planet K2-18b in Habitable Zone
Scientists using NASA’s James Webb Space Telescope have detected potential signs of life on the distant exoplanet K2-18 b, located 124 light-years away in the constellation Leo. The telescope identified the presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS)—gases on Earth produced only by living organisms like algae.
Scientists using NASA’s James Webb Space Telescope have detected potential signs of life on the distant exoplanet K2-18 b, located 124 light-years away in the constellation Leo. The telescope identified the presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS)—gases on Earth produced only by living organisms like algae. While not confirming alien life, the discovery suggests a possible biological process at work. K2-18 b, a “mini-Neptune” 8.6 times Earth’s mass, lies within its star’s habitable zone where liquid water may exist. Previously, Webb had found methane and carbon dioxide there, marking the first carbon-based molecules observed in a habitable-zone exoplanet’s atmosphere. Lead researcher Nikku Madhusudhan called the discovery a “transformational moment” in the quest to find extraterrestrial life. Alien Life Existed on Mars?
