Saturn’s rings, shadows and moons

From the Cassini Orbiter, just like looking over Saturn’s shoulder.

Saturn’s moon Tethys casts a shadow on the planet’s A ring alongside the larger shadow cast by the planet itself in this image taken as Saturn approached its August 2009 equinox.

The night side of the planet is dimly lit here by ringshine. Tethys, located off to the left of this image, is not seen. The moon Janus can be seen orbiting outside the thin F ring at the top of the image. Other bright specks are background stars.

Thanks Saturn.
