Enceladus, the sixth largest of Saturn’s moons, is known for spraying out tiny icy silica particles — so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus’ core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.
