Two of Neptune’s narrow rings are visible as arches above the crescent planet. The inner ring, LeVerrier, is uniform but the outer ring, Adams, contains three visible arcs. The arcs are designated, from bottom to top, Liberte, Egalite and Fraternite. A smaller arc, Courage, leads the other three but falls outside this field of view. Voyager 2 acquired this image as it encountered Neptune in August of 1989.
