Presentation: “Discovery of Saturn’s Largest Ring” by Anne Verbiscer, University of Virginia
Anne Verbiscer presented amazing information about an outstanding discovery that she, Michael Skrutskie, and Douglas Hamilton made.  With help from the Spitzer satellite, they discovered the largest ring ever found around Saturn.  They were investigating the area around the orbit of Phoebe, a moon with an extremely large orbital radius and tilt that orbits in the opposite direction of other moons.  Along the path, a ring of widely scattered ice, dust, and debris was discovered, that is not dense enough to reflect or block visible light.  The height of the ring is equivalent to 10 Saturn diameters.  This is a quite a difference from the known rings that are easily visible and thin, as compared to the size of the planet Saturn.
This was actually the first public presentation of her discovery since the announcement was made on October 7th.
More information, associated links, and an artist’s drawing about the discovery can be found on the RAS home page.
