Astronomers have detected potential signs of biological activity on exoplanet K2-18b using the James Webb Space Telescope.
Chemical fingerprints of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) were found in the planet's atmosphere, suggesting the presence of life-based molecules.
The discovery has reached a 'three-sigma' level of statistical significance, hinting at potential biological activity beyond our solar system.
Scientists remain cautious about jumping to conclusions and plan further observations to confirm the presence of life on K2-18b.
