The Rings of Saturn

All the gas giants in our solar system have rings. However, no planet have more pronounced rings than Saturn. While their origin and reason for existing remains a mystery, it is clear that they are not governed exclusively by gravity. There is something self-healing about them that implies a much stronger force than gravity. When disturbed by a passing moon, the rings quickly revert to their initial stable configuration.

At the beginning of the 20th century, Kristian Birkeland produced a ring effect around a magnetized terrella, strikingly similar to the rings observed around Saturn. Recently a similar effect has been observed around water drops exposed to a strong electric field. What seems certain is that the rings of Saturn are electromagnetic in nature.
