New "Ringlets" (2)
|
Caption NASA:"HR Cassini images show an astonishing level of structure in Saturn's Cassini Division, including two ringlets that were not seen in NASA Voyager spacecraft images 25 years ago.
This view was taken with the Sun almost directly behind Saturn and its Rings, a viewing geometry in which microscopic ring particles brighten substantially. The image shows the diffuse new ringlet in the Cassini Division as the brightest feature in that Region.
This image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 15, 2006, at a distance of approx. 2,2 MKM (such as about 1,4 MMs) from Saturn. This view looks toward the unlit side of the Rings from about 15° above the ringplane. The phase angle, or Sun-Saturn-spacecraft angle, was 179°. Image scale on the sky at the distance of Saturn is roughly 13 Km (such as about 8 miles) per pixel".
