Over the past year, astronomers have been able to study Saturn's rings in detail with the Hubble Space Telescope. In his Perspective, Murray discusses three accompanying papers that describe new results, including observation of OH molecules above the rings, high-quality images of the braided F ring, and the finding that two of the satellites that affect the ring dynamics—Prometheus and Atlas—are out of their expected positions.
