K2-18b: Life... Out There?

Are we truly alone in the universe? Scientists have detected intriguing chemical signatures in the atmosphere of exoplanet K2-18b, 124 light-years away—a Hycean world unlike Earth, yet possibly habitable. Using the powerful James Webb Space Telescope, researchers found compounds like dimethyl sulfide, a molecule on Earth produced almost exclusively by marine life. Could this be the first whisper of alien biology? Or is there another explanation? Join us on this breathtaking journey across space and science, as we explore what might be the closest hint yet of life beyond Earth.
