Saturno e Dione



Saturn and Dione, with ringshineI dug this image out of the Planetary Data System to show you what ringshine looks like. Cassini looked edge-on to Saturn's rings to capture this approximately true color view of icy white Dione and the globe of Saturn on November 21, 2005. The rings are so thin that they almost disappear, but their effect is visible in the wash of yellow light they reflect onto the night side of Saturn's southern hemisphere (below the rings in this image). The north side of the rings is the unlit side, so there is no ringshine visible on the night side of Saturn's northern hemisphere.
