Caption NASA:"The Cassini Spacecraft looks at Saturn's largest moon, Titan, revealing its halo-like ring formed in the upper hazes of the moon's extensive Atmosphere.
This view looks toward the darkened Leading Hemisphere of Titan, but lit terrain seen here is on on the Trailing Hemisphere and anti-Saturn side of the moon.
The moon's North Pole lies on the Terminator between the illuminated and unilluminated parts of the moon. The Pole is rotated 11° to the right in this image.
The image was taken with the Cassini Spacecraft narrow-angle camera on July 5, 2009 using a spectral filter sensitive to wavelengths of UltraViolet light centered at 338 nanometers. The view was acquired at a distance of approx. 1,3 MKM (about 808.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 148°.
Image scale is roughly 8 Km (about 5 miles) per pixel".
