Saturn’s largest moon, Titan, is a complex environment. It hosts rivers and lakes of liquid methane, fields of icy boulders, extensive sand dunes, and, beneath its frozen crust, a vast subsurface ocean. This unique combination makes Titan one of the most intriguing subjects in astrobiology.

A new study led by ETH Zurich fellow Dr. Antonin Affholder examines whether that subsurface ocean could support life. His findings, discussed in a recent SETI Live with SETI Institute communications specialist Beth Johnson, suggest that if life exists there, it may persist only in extremely small amounts, making detection a formidable challenge.
