One of the great mysteries of Saturn’s largest moon, Titan, is the temporary smoothness of its hydrocarbon lakes in places, a state that sometimes last for days or weeks. Planetary geologists have come up with two potential explanations for this smoothness. The first is a lack of waves. Perhaps there just isn’t enough wind on Titan to drive waves across the entire surface of its lakes.
