Night-lights, in the Saturnshine...
|
Caption NASA originale:"Soft light from Saturn lifts the veil of night from the moons Dione (lower left) and Rhea (upper right).
A scant crescent on each satellite marks the limit of the Sun's direct reach. The remaining light is reflected onto the moons by the Ringed Planet (Saturn-shine).
This view was acquired using an image compression scheme that results in minor artifacts being present - on Rhea in particular.
Rhea (approx. 1.528 Km, or 949 miles across - pictured above) is somewhat bland in appearance at this image scale, although Dione's spectacular fractures stand out marvelously. Dione is approx. 1.126 Km (about 700 miles) across.
North, on both moons, is rotated 45° to the right.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 11, 2006 at a distance of approx. 2,6 MKM (about 1,6 MMs) from Dione and 2.8 MKM (1,7 MMs) from Rhea. Image scale is about 15 Km (approx. 10 miles) per pixel on Dione and about 17 Km (approx. 11 miles) on Rhea".
