James Webb Just Found What Looks Like Life... And It's Already Gone

Astronomers using the James Webb Space Telescope detected potential biosignatures, specifically dimethyl sulfide (DMS), on the exoplanet K2-18b. While initially seen as evidence of alien life on a \"Hycean\" world, subsequent re-analyses and the discovery of abiotic DMS in space have cast doubt on these findings, highlighting the immense difficulty of confirming extraterrestrial life from a distance.
