"James Webb Telescope Discovers Signs of Alien Life on Exoplanet K2-18b"
NASA's James Webb Space Telescope has detected methane, carbon dioxide, and dimethyl sulphide (DMS) in the atmosphere of exoplanet K2-18b, located 124 light-years from Earth. The presence of DMS, a molecule only produced by living things on Earth, suggests the possibility of life on the planet. K2-18b is considered a potentially habitable world, with a hydrogen-rich atmosphere and a liquid-water ocean, making it a candidate for a Hycean planet. Further research is needed to validate the evidence of DMS and determine if the exoplanet can support life.

JWST's Discovery: Intelligent Civilization Found on Earth
Originally Published 2 years ago — by Phys.org
A recent study suggests that if Earth were an exoplanet, the James Webb Space Telescope (JWST) would be able to detect the presence of an intelligent civilization by analyzing the molecules in our atmosphere. By simulating the data obtained from Earth's atmosphere and introducing noise and lower resolutions, the study found that JWST could identify various molecules, including those indicative of an industrial civilization. The study also demonstrated that JWST could potentially identify biological and technological signatures on exoplanets within 50 light-years, such as those in the Trappist-1 system. This research could significantly advance our understanding of life in the universe.
