Extreme methane rainstorms appear to have a key role in shaping Titan’s icy surface. Titan, the largest of Saturn’s more than 60 moons, has surprisingly intense rainstorms, according to research by a team of UCLA planetary scientists and geologists. Although the storms are relatively rare – they occur less than once per Titan year, which is 29 and a half Earth years – they occur much more frequently than the scientists expected.

“I would have thought these would be once-a-millennium events, if even that,” said Jonathan Mitchell, UCLA associate professor of planetary science and a senior author of the research, which was published Oct...
