Flying Saucers and the Rings of Saturn

This story is at www.dailygalaxy.com March 17th … and concerns weird flying saucer shaped moons in the rings of Saturn that have intrigued astronomers after seeing them on images transmitted by the Cassini spacecraft. A paper in the December 6th issue of Science says the two Yorkshire Pudding shaped Aunt Bessie like moons seem to be formed from the same material as the rings themselves. They are in effect, clumps of ice and dusty accretions. The actual flying saucer shape is found elsewhere in the universe – around what are thought to be black holes, around stars, around Jupiter etc. Does the shape have an electrical origin? If so, are those flying saucers of UFO fame perhaps a form of lightning?
