Titan in Eclipse
|
Caption NASA:"The Cassini spacecraft captured this image of a dimly lit Titan as Saturn's largest moon was eclipsed by the Planet.
This view looks up toward the South Pole of Titan which lies on the Terminator about a quarter of the way inward from the right of the visible disk. Lit terrain seen here is on the Saturn-facing side of Titan. In Saturn's shadow, the Southern Hemisphere of Titan is lit by two sources: sunlight scattered through the Planet's Rings and refracted sunlight passing through the edge of Saturn's Atmosphere.
Stars in this image are smeared by the long camera exposure time of 560" needed to capture the faint light on Titan. The image was taken in Visible Light with the Cassini Spacecraft wide-angle camera on May 7, 2009. The view was acquired at a distance of approx. 667.000 Km (about 414.000 miles) from Titan and at a Phase Angle of 58°.
Image scale is roughly 40 Km (about 25 miles) per pixel".
