Mysterious Objects Punching Holes In Weird Saturn Ring

"I think the F ring is Saturn's weirdest ring, and these latest Cassini results go to show how the F ring is even more dynamic than we ever thought," Carl Murray, a Cassini imaging team member based at London's Queen Mary University, said in a statement. "These findings show us that the F ring region is like a bustling zoo of objects from a half mile in size to moons like Prometheus a hundred miles in size, creating a spectacular show." The F ring is held in check by two tiny moons, Prometheus and Pandora, which weave inside and outside the outer ring. Sometimes these moons perturb the ring, creating channels and snowballs. Now scientists think that some of these snowballs survive to become the weird objects punching new holes in the ring. [Video here, after commercial]
