À propos de cet audio
124 light-years away, the exoplanet K2-18b sits in its star's habitable zone. Is it a potential cradle for life? The James Webb Space Telescope detected intriguing molecules like methane and CO2 in its atmosphere, consistent with a hypothetical water-covered "Hycean" world.
But the real buzz surrounds the potential detection of dimethyl sulfide (DMS) – a gas primarily produced by life on Earth. We dive into the provocative JWST findings, the intense scientific debate surrounding the signal's strength, the possibility of non-biological origins, and the conflicting analyses challenging the initial claims.
Is this the strongest evidence yet for extraterrestrial life, or a complex puzzle of alien atmospheric chemistry? Join us as we explore the science, the skepticism, and the ongoing search for answers on K2-18b.
