How does material from Enceladus create Saturn’s E ring?

Saturn’s E ring is a tenuous, broad structure composed of micrometre-sized water ice particles. These particles are continuously supplied by cryovolcanism—specifically, eruptions from geysers located in a thermally active region near the south pole of the moon Enceladus.12

These geysers eject water vapour and ice from the moon's interior, which then condense into the small particles that form the ring. Because the orbital lifetimes of these particles are relatively short—estimated at approximately 10,000 years—the ring requires constant replenishment from Enceladus’s ongoing geological activity. The density of these particles is highest near the orbit of Enceladus, and the material eventually spreads to coat the moon and other inner satellites of Saturn, giving them a bright appearance.1
