Another amazing Cassini shot of Saturn. Here's a stat. The distance from the inside of the rings to the outside of them is over 300,000km. That means Australia for example could be laid end-to-end at least 10 times across the rings. The rings are made of trillions of pieces of ice, thought to be one of Saturn's many moons, obliterated about the time of the dinosaurs by Saturn's enormous gravity. The debris then formed those beautiful circular rings, caused again by Saturn's enormous gravity. Oh, and it rains diamonds on Saturn.
