• Neptune's Great Dark Spot
    Download Image
    These images of the Great Dark Spot were taken by Voyager 2 over a 4 1/2 day period at intervals of 18 hours. As shown on the left, a "tail" of the dark spot separated into individual spots that moved westward. The Great Dark Spot may have an overall counterclockwise rotation as suggested by the lighter toned clouds surrounding the main spot.
