NASA’s James Webb Space Telescope has just made a discovery that could change everything we know about the universe. By detecting carbon dioxide, methane, and potentially dimethyl sulfide (DMS) in the atmosphere of exoplanet K2-18b, scientists might be on the brink of confirming life beyond Earth. On Earth, DMS is only produced by living organisms, mainly marine life, so its presence on K2-18b, 120 light-years away, has sparked massive excitement. But here’s the catch—this detection isn’t fully
