The surface of Saturn’s moon Dione is rendered in crisp detail against a hazy, ghostly Titan. A portion of the ”wispy” terrain of Dione’s trailing hemisphere can be seen on the right (see Wispy Marble). Also visible in this image are hints of atmospheric banding around Titan’s north pole. This view looks toward the Saturn-facing hemisphere of Dione (1,123 kilometers, or 698 miles across) and Titan (5,150 kilometers, or 3,200 miles across).
The image was taken in visible blue light with the Cassini spacecraft narrow-angle camera on April 10, 2010. The view was acquired at a distance of approximately 1.8 million kilometers (1.1 million miles) from Dione and 2.7 million kilometers (1.7 million miles) from Titan.
Scale in the original image was 11 kilometers (7 miles) per pixel on Dione and 16 kilometers (10 miles) on Titan. The image has been magnified by a factor of 1.5 and contrast-enhanced to aid visibility. Credit Cassini.
