The sad thing is that Saturn's ring system will eventually break down (unless new material is added). I learned in astronomy class that huge, elaborate ring systems quickly break down to a more sustainable size, like the rings we see around the other giant planets.
Even sadder is that we're living in the last age of total solar eclipses on Earth. The moon has been steadily moving away from the Earth with time: Today, the moon at its closest is only slightly larger, in apparent terms, than the sun, and at farther orbits it is already slightly smaller (which is where annular solar eclipses come from). It's quite a remarkable coincidence that at this moment in history the moon and the sun are almost exactly the same relative size in the sky. (It's also at least somewhat fortuitous that the plane of the moon's orbit is so similar to the plane of Earth's orbit around the sun, which increases the frequency of solar eclipses drastically. However, unlike the identical relative size thing, this happenstance is only partially coincidental.)
