Montage of Saturn and several of its satellites, Dione, Tethys, Mimas, Enceladus, Rhea, and Titan. JPL image PIA01482: Saturn System Montage This montage of images of the Saturnian system was prepared from an assemblage of images taken by the Voyager 1 spacecraft during its Saturn encounter in November 1980. This artist's view shows Dione in the forefront, Saturn rising behind, Tethys and Mimas fading in the distance to the right, Enceladus and Rhea off Saturn's rings to the left, and Titan in its distant orbit at the top.

Animation of three discovery images of Saturn's irregular moon Skathi (S/2000 S 8; circled), taken by the 3.6-meter Canada-France-Hawaii Telescope (CFHT) on 23 September 2000. Each image was taken approximately 90 minutes apart, showing the moon's motion relative to the background stars and galaxies. The raw image datasets used are 550468p, 550478p, and 550490p. For comparison, the star field in these images can be viewed at the CDS's Aladin star atlas.
