1. NASA Finds Saturn's Moons May Be Creating New Rings October 11, 2006 http://saturn.jpl.nasa.gov

2. With giant Saturn hanging in the blackness and sheltering Cassini from the sun's blinding glare, the spacecraft viewed the rings as never before, revealing previously unknown faint rings and even glimpsing its home world. This marvelous panoramic view was created by combining a total of 165 images taken by the Cassini. Credit: NASA/JPL/Space Science Institute

3. Under present knowledge Saturn has 56 satellites and seven main rings (A,B,C,D,E,F,G).
