Focus on Enceladus Ring shadows line the face of distant Saturn, providing a backdrop for the brilliant, white sphere of Enceladus. This icy moon, with its heavily modified surface and towering plume of icy material, is a target of intense study for Cassini during its Equinox mission. This image looks toward the leading side of Enceladus (504 kilometers, or 313 miles across) and was taken in visible green light with the Cassini spacecraft narrow-angle camera on June 28, 2007. The view was acquired at a distance of approximately 291,000 kilometers (181,000 miles).
