Astronomers searching for alien life aimed the James Webb Space Telescope at K2-18 b, a potentially ocean-bearing world 124 light-years away, and found tentative signs of gases associated on Earth wit

Astronomers using the James Webb Space Telescope have identified tentative spectral signatures of dimethyl sulphide on the exoplanet K2-18 b. While these gases are associated with marine life on Earth, researchers emphasize that this is not a confirmed detection of alien life and requires further study.
