Vanishing Pan... (Natural Colors; credits: NASA/JPL/Space Science Institute)

Caption NASA originale:"The Cassini spacecraft looks down at the unlit side of the Rings as Pan heads into Saturn's shadow. The moon is accompanied by faint ringlets in the Encke Gap. At bottom, the bright F-Ring core fades slowly into darkness. This view looks toward the unlit side of the Rings from about 20° above the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Nov. 15, 2006. Cassini was then at a distance of approx. 1,7 MKM (about 1,1 MMs) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, Angle of 163°. Image scale is roughly 10 Km (approx. 6 miles) per pixel".
