What are the rings of Saturn?

Shinning rings of billions of tiny chips of ice, rock and dust surround Saturn. The rings reflect light strongly and can be clearly seen through a telescope from the Earth. It was first thought that Saturn had three wide rings, but it is now known that the rings are actually made of thousands of narrow ringlets. The rings are only 100 meters thick, but they extended into space for 76,000 km. The material in the rings was probably capture3d by Saturn's gravity when the solar system was forming, or it might be the remains of a moon that has broken up. Recently, space probes discovered that some rings are braided, or twisted, but so far there is no explanation for this strange effect.
