Saturn and its moons from Voyager 2 Voyager 2 captured the images for this view of Saturn on July 12, 1981. Three moons are visible: Rhea below the disk, and Tethys and Enceladus on the disk. Tethys' shadow falls on the planet. The image was taken on the same day as this more garish view that was released by NASA. NASA / JPL / Ian Regan
