There are two pictures of Saturn on this page. The top one is in ultraviolet light. A crown of light is visible. This is the first ever picture of bright auroral lights around the north and south poles of Saturn. The ring of light around the south pole can barely be seen because Saturn is tipped away from us. The crown of light looks just like the ones in the ultraviolet images of Jupiter and Earth. If you haven't seen these yet, you may want to go back to the page of planet views and take a look.

The lower picture of Saturn is in visible light. Just like for Jupiter, you can see cloud bands in the visible image but not in the ultraviolet image. These spectacular pictures were taken by the Hubble Space Telescope.
