Life in Titan's Ocean? The Microscopic Possibility of Biomass on Saturn's Moon

Saturn's largest moon, Titan, is a world of methane rivers and lakes, icy boulders, sandy dunes, and a vast subsurface ocean. Could this distant world harbor life? A new study led by Dr. Antonin Affholder, now a fellow at ETH Zurich, suggests that Titan's ocean might support life—but only in the tiniest amounts, making it incredibly hard to find. Join communications specialist Beth Johnson as she chats with Dr. Affholder to explore what this means for the search for life beyond Earth, why organics on Titan may not provide enough fuel, and how NASA's Dragonfly mission might help answer these questions.
