Cassini's data showed that the rings were unusually bright and free of darkening, which would typically occur if micrometeoroids—tiny space rock particles—were hitting them. This pristine ...
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 ...
Images by Cassini showed no evidence of any darkening of the rings by impacting micrometeoroids — space rock particles smaller than a grain of sand — prompting scientists to conclude the rings ...
