What are the rings of Saturn?

Shining 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 100m thick, but they extend into space for 76000km. The material in the rings was probably captured by saturns 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 of the rings are braided, or twisted, but so far there is no explanation for this strange effect.
