Proof that the rings are incomplete first began in the mid-1980s, when stellar occultation were found to rarely show an extra "blink" just before or after the planet occulted the star. Pictures from "Voyager 2" in 1989 solved the problem when the ring system was found to have several faint rings. The farthest ring, Adams, has three famous arcs now named "Liberté", "Egalité", and "Fraternité" (Liberty, Equality, and Fraternity).
