Saturn's infrared ring

The Spizter Space Telescope has discovered a gigantic ring, visible in the infrared, around Saturn. If the ring, shown here in an artist's rendition, were visible on Earth, it would be twice the width of the full moon. The new ring is tilted 27 degrees from the main ring plane and follows the orbit of Saturn's retrograde moon Phoebe, which is the presumed source of the ring's material. The discovery team was led by Anne Verbiscer at the University of Virginia, Charlottesville.
