Titan, Saturn’s largest moon, may not have a continuous underground ocean like scientists initially thought. A reanalysis of Cassini data reveals that the moon is losing heat, suggesting a slushy interior instead of a liquid sea. Researchers compared Titan’s gravity models with lab-tested ice physics and found that small errors could hide a time lag unless analysts squeezed the noise down. The study suggests that most of the heat loss happens deep within the moon, where high-pressure ice can sit near melting and behave like slush. This could affect our understanding of life on Titan, as water’s ability to circulate nutrients from rock is crucial for life.
