Black Shadow from the "White Moon" (Natural Colors; credits: Lunar Explorer Italia)

Caption NASA:"The shadow of Saturn's moon Enceladus cast onto the Planet's Atmosphere appears like a drop of black ink on a canvas of Saturnian storms.

The image was taken with the Cassini spacecraft narrow-angle camera on June 20, 2008 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 750 nanometers. The view was obtained at a distance of approx. 1,3 MKM (such as about 810.000 miles) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, Angle of 24°.
Image scale is roughly 7 Km (about 4 miles) per pixel".
