Enhanced Vision Saturn’s magnificent rings constitute one of the most beautiful features in our solar system, and Cassini has revolutionized our understanding of their makeup. Cassini data taken at stellar occultations have revealed that the rings are not clouds of uniformly distributed particles but, instead, have areas—such as the A and B rings—composed of densely packed clumps with nearly empty spaces between them. In this false-color image from 2007, the rings are represented (from left) as C, olive; B, blue and yellow; the Cassini division, olive; and A, blue. NASA/JPL/University of Colorado
