Picture of the Day: Rhea, Saturn's Icy Moon


Taken on January 11 by NASA's Cassini spacecraft from about 37,000 miles away, this wide-angle photograph shows Saturn's icy moon Rhea. The line coming in from the right side of the photograph is Saturn's rings and the three small dots scattered around the image are more of the planet's moons. The moon just above Rhea is Dione, the large circle on the extreme left side of the photograph is Tethys, and the small dot between the two is Epimetheus.
