This artist's concept envisions what hydrocarbon ice forming on a liquid hydrocarbon sea of Saturn's moon Titan might look like. A new model from scientists on NASA's Cassini mission suggests that clumps of methane-and-ethane-rich ice--shown here as the lighter-colored clusters--could float under some conditions.
