Saturn's Rings Are Disappearing

Saturn's rings are not only younger than previously thought but are also disappearing rapidly. The rings, composed mainly of water ice, are being pulled into Saturn by gravity, reacting with its ionosphere. Observations using the Keck telescope and data from Voyager missions suggest the rings formed less than 100 million years ago and may vanish in 300 million years.
