If scientists could weigh Saturn's rings, they could estimate the amount of time it would take for them to accumulate enough contaminants to get 1 percent impure and thus calculate their age, lead study author Luciano Iess, a planetary scientist at the Sapienza University of Rome, told. A few years back, NASA's Saturn-orbiting Cassini mission determined that the rings are only about 1 percent impure. The rings were initially made of bright ice, but over time have become contaminated and darkened by debris from the outer reaches of the solar system. One way to solve this mystery is to weigh Saturn's rings. Others suggested the rings are very young, perhaps originating after Saturn's gravitational pull tore apart a comet or an icy moon. Some researchers had thought the iconic features formed along with the planet about 4.5 billion years ago from the icy rubble left in orbit around it after the formation of the solar system.
