Scientists Find Promising Indication of Extraterrestrial Life—124 Light-Years Away

Astronomers using the James Webb Space Telescope have detected potential biosignatures of marine microorganisms on exoplanet K2-18b, located 124 light-years away. Researchers found traces of dimethyl sulfide and dimethyl disulfide in the planet's atmosphere, compounds produced only by microbial life on Earth. K2-18b, a potential Hycean planet with vast oceans and a hydrogen-rich atmosphere, is 8.6 times Earth's mass and orbits a red dwarf star. This discovery represents the strongest evidence to date for possible extraterrestrial life on another planet.
