Saturn’s Intricate Rings Are Incredibly Thin [film clip]

From the film "Kingdom of Saturn" - on Amazon:
Since Galileo first noticed something odd about Saturn in 1610, the rings have posed many fascinating puzzles. Over the past 13 years, the American-European Cassini-Huygens Mission has solved many of them. Made mostly of water, the rings are very old, yet they are kept startlingly bright. The particle sizes vary wildly. They are in constant change under the pull of many moons. And they are surprisingly flat – more than 30 millions times wider than they are high. Saturn's rings are much like the squashed disk of material that orbited the infant Sun, more than 4 billion years ago, giving scientists a window across time to gather clues to the formation of planets.
"Kingdom of Saturn –Cassini's Epic Quest" is a 73-minute documentary, available at Amazon Xive-TV, from director @DavidSkyBrody and executive producer Thomas Lucas.
