I had read this article as well, found it pretty facinating because since I was a child Saturn has always facinated me. I remember the time when it was taught that Saturn was the only planet to have rings, and then they found darker rings around neptune as well observed around 1983. I was still quite young at the time, and with no access to the internet and its wealth of knowledge it wasn't for a few years that I 'discovered' neptune's rings
I wouldn't be surprised if in a hundred thousand years from now the rings around neptune would be notably more significant as the collection of space debris brought and caught in the rings orbit causes it to grow and what not.
The speed of which Saturn's rings rotate makes it..difficult..to go in and study them, but I am still looking for more articles about the different types of particles and elements that could be found within the rings and debris.
Space is just facinating because there is just so much of it, and I would be very surprised if there weren't new and interesting things that we have not yet discovered..perhaps new elements, or quite possibly new lifeforms (Yes I believe in 'aliens" no I do not believe there are life forms that abduct people named "bubb" for anal probing..>.>) anywho.../endramble
edit: I should note that I was all of 6 years old when I learned about saturn, and was under the assumption it was the only planet with rings
