Photo of the Day: Crescent moons below Saturn's rings

Saturn's moons Enceladus and Tethys adorn Saturn's rings in this image from the Cassini spacecraft.

Enceladus (313 miles, or 504 kilometers across) appears just below the rings here, near the center of the image. Tethys (660 miles, or 1,062 kilometers across) is near the bottom center of the image. Tethys is closer to Cassini than is Enceladus.
