Saturn's rings might not be younger than the dinosaurs as recently suggested, but nearly as old as the giant planet itself at billions of years in age, a new study says.
The age of Saturn's rings has long been controversial. Some researchers had thought the iconic features formed along with Saturn about 4.5 billion years ago from the icy rubble left in orbit around it after the birth of the solar system. Others suggested the rings are very young, perhaps originating after Saturn's gravitational pull tore apart a comet or an icy moon.
