Titan Isn’t What We Thought: New Evidence Wipes Out the Case for a Buried Ocean
A new Nature study reexamines Cassini radio‑tracking data and finds Titan’s interior dissipates far more tidal energy than previously thought. The measured 3–4 TW of heat loss cannot be reconciled with a global subsurface ocean, prompting a shift to a model of a thick, high‑pressure ice layer near its melting point. This “slushy” ice may contain isolated liquid pockets but lacks a continuous ocean, challenging Titan’s status as a classic ocean world. Upcoming Dragonfly measurements will provide direct tests of the revised interior structure.
