information was found in the mid-1980s that suggested that the rings were not completely formed. stellar occultations were found that rarely showed an extra "blink" just before or after the planet moved in front of the star. pictures from "voyager 2" in 1989 answered the problem. the pictures showed that the ring system had several faint rings. the farthest ring, adams, has three arcs now named "liberté", "egalité", and "fraternité" (liberty, equality, and fraternity).
