SATURN AND ITS RINGS 1.0 INTRODUCTION Saturn and its rings are the most extensive planetary ring system found in any planet in the Solar System. They are made of countless small particles that range in size from micrometers to meters that form clumps that orbit about Saturn. The ring particles as discovered are made almost entirely of water ice including some contamination of dust and other chemicals. The reflections from the rings increases Saturn's brightness but the rings themselves are not visible from Earth with unaided vision. 1610 was the year it was discovered, this was Galileo Galilei when he turned his telescope to the sky, Galileo became the very first person to observe the rings, but he could not see them clearly enough to discern their true nature. In 1655, Christiaan Huygens became the first person to ...
... 4.8 billion years ago. Under this model, remnants of material within the Roche limit could not condense and would become rings. However, in recent years this idea seems to be flawed. The rings appear to be young, perhaps only hundreds of millions of years old. One of the clues to this theory is that the rings are bright. As Saturn travels though space, the rings accumulate dust particles that have been darkened from solar radiation. If the rings were old, they should appear dark. Another theory suggests that perhaps a comet few too close to Saturn and tidal forces broke it into pieces similar to comet Shoemaker-Levy/9. Perhaps one of Saturn's moons was struck by an asteroid smashing it into the bits and pieces that form the rings. Hopefully the Cassini spacecraft can answer some of these questions.
