Scientists have long suspected that a vast ocean of liquid water lies under the crusty exterior of Titan, Saturn's largest moon. New analysis suggests that the internally generated heat that keeps that ocean from freezing relies on the moon's interactions with Saturn and its other moons.
A new analysis of topographic and gravity data from Titan, the largest of Saturn's moons, indicates that Titan's icy outer crust is twice as thick as has generally been thought.
Scientists have long suspected that a vast ocean of liquid water lies under the crust. The new study suggests that the internally generated heat that keeps that ocean from freezing solid depends far more on Titan's interactions with Saturn and its other moons than had been suspected.
