If you were soaring above the surface of Saturn’s largest moon, Titan, you’d see mountains, rivers, lakes, and seas, but you might also run into a monsoon-like rainstorm. Severe weather doesn’t happen very often on Titan, but new research suggests than when it does, the skies unleash torrents of liquid methane that floods and carves the moon’s icy surface.
Titan is the largest of Saturn’s 60 moons, which is roughly the size of Mercury. A visitor from Earth would recognize many features, including an atmosphere, volcanoes, mountains, and sand dunes. And like Earth, Titan features free-flowing liquid at the surface, manifesting as rivers, lakes, and seas.
