On April 4, 2009, telescopes around the world will be trained on Saturn during the 100 Hours of Astronomy, a global sky-observing fest in honor of the astronomer Galileo Galilei. To join the celebration, the Cassini Imaging Team has collected here some of its most memorable images and movies of Saturn and its rings and moons ... a collection Galileo would be proud of. It's all part of the International Year of Astronomy which marks 2009 as the 400th anniversary of Galileo's first astronomical use of the telescope.
The Saturnian system consists of the solar system's second largest gaseous planet surrounded by beautiful rings, dozens of moons, and one intrepid robotic explorer. Learn the answers to frequently asked questions about Saturn and Cassini here.
