A single crescent moon is a familiar sight in Earth's sky, but with Saturn's many moons, you can see three or even more. The three moons shown here - Titan (3, 200 miles across), Mimas (246 miles across), and Rhea (949 miles across) - show marked contrasts. Titan, the largest moon in this image, appears fuzzy because we only see its cloud layers. And because Titan's atmosphere refracts light around the moon, its crescent wraps just a little further around the moon than it would on an airless body. Rhea (upper left) appears rough because its icy surface is heavily cratered. And a close inspection of Mimas (center bottom), though difficult to see at this scale, shows surface irregularities due to its own violent history. This view looks toward the anti-Saturn hemisphere of Titan. North on Titan is to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 25, 2015. | |
