loginA stunning ring systemSaturn's rings are a marvellous collection of rock and ice, some as small as dust, some as large as mountains. But the age of the rings isn't known. In its final flybys, Cassini mapped the gravity fields of the rings, in essence trying to weigh them. The more massive they are, the older they would be, perhaps as old as the solar system itself, around 4.6 billion years. If lighter, they could be just hundreds of thousands of years old, which preliminary findings suggest may be the case.
