NASA’S  Cassini mission explored Saturn for a decade and provided lots of interesting information on its gravitational field. But ,lots of questions remained unanswered about the rings of Saturn. According to Astronomers,  Saturn’s rings weigh about 33 million trillion pounds. The rings are formed of 95 percent pure water ice and continuously fade over time. However, some recent studies suggest that Saturn’s rings could be as young as 10 million years old. Other astronomers believe the rings could be as old as our solar system itself. The mystery of the rings remains unresolved. Perhaps, another mission to Saturn would be able to provide sufficient information to solve the mystery of these rings.
