James Webb Could Spot Alien Life on K2-18 b | 99.7% Sure | 124 Light-Years Off

Using James Webb Space Telescope observations of K2-18b as a starting point, this video reviews the latest advancements in the field of exoplanet atmospheric exploration. This super-Earth, located in the constellation Cetus and 124 light-years from Earth, has long been considered a leading candidate in the search for extraterrestrial life. The video focuses on the signal of dimethyl sulfide (DMS) detected in the atmosphere of K2-18b by the Webb telescope. If confirmed, this discovery would suggest the possibility of life activity beyond Earth — since DMS on our planet is primarily produced by marine plankton, with a 99.7% confidence level. The key highlights include how scientists interpret potential biological signals from spectral data and the significance of this finding for the reboot of SETI (Search for Extraterrestrial Intelligence). The video also presents the cautious attitude of the scientific community, avoiding blind optimism. It is suitable for astronomy enthusiasts, science fiction fans, and anyone interested in the origins of life in the universe. It is recommended to read related popular science articles to gain a more comprehensive understanding of the technical principles and limitations of exoplanet atmospheric detection.
