Deep in our solar system, a new era of exploration is unfolding. Beneath the thick ice of Europa; in the vapor plumes on Enceladus; and within the methane lakes of Titan, scientists are hunting for extraterrestrial life. These moons are 'ocean worlds'— they contain liquid oceans, which can support the formation of life. Does life exist on ocean worlds? Augusto Carballido explores the possibility.
