[<I>Cassini</I> approaches Saturn]
As the spacecraft Cassini approached Saturn in 2004, it photographed the planet from underneath its rings. The southern hemisphere of Saturn was in summer. Notice how Saturnís shadow falls on the rings of this magnificent planet. The three small star like objects in the picture are moons orbiting the planet.
