Voyager 1 image showing the southeastern half of the Valhalla ring structure on Jupiter's satellite, Callisto. The center of Valhalla, 16 N, 57 W, is at the top of the frame. The bright central area is about 300 km across, the concentric rings extend as much as 1500 km from the center. The feature is similar to large impact basin on the Moon. Callisto is 4,800 km in diameter. North is at 10:30. (Voyager 1, FDS 16418.38)
