Icy Plumes in the Ring-Shine

Caption NASA originale:"The plumes of Enceladus continue to gush icy particles into Saturn orbit, making this little moon one of a select group of geologically active bodies in the solar system.
Enceladus (505 Km, or 314 miles across) is seen here against the night side of Saturn. The extended exposure time used to image the plumes also makes the Southern Hemisphere, illuminated by Ring-Shine, appear bright.

The image was acquired in visible light with the Cassini spacecraft narrow-angle camera on May 4, 2006 at a distance of approx. 2,1 MKM (about 1,3 MMs) from Enceladus and 2,3 MKM (about 1,5 MMs) from Saturn. The image was taken at a Sun-Enceladus-spacecraft, or phase, angle of 159°. Image scale is roughly 13 Km (such as about 8 miles) per pixel on Enceladus".
