The Cassini spacecraft was a project launched by NASA, the European Space Agency and the Italian Space Agency that has yielded large amounts of useful data and many beautiful pictures. This one in particular shows the C ring on the right, and the B on the left. The red hues indicate dirty particles and blue the cleaner ice. The rings of Saturn are labelled from the inside out with rings, D, C, B, and A, followed by F, G, and E. In order to image the rings in such quality the Cassini spacecraft used its Ultraviolet Imaging Spectrograph in resolution some 100 times that of the Voyager 2 spacecraft.
