How Saturn’s Rings Might Be Keeping A Youthful Appearance
Even though Saturn's rings appear clean and young, they may be as old as the planet itself according to international researchers. It was previously thought that impacts with small rocky debris travelling through space - called micrometeoroids - would dirty and darken the rings over time, but in 2004 the Cassini spacecraft revealed the rings to be clean and bright suggesting that they are not very old.
