Not earthshaking for sure but it does solve a mystery about the moon Iapitus, the facing side was black as coal and the back side white as snow.
Now it has been shown to be due to the dust in the ring coating the forward side, probably for millions of years. It is interesting because it was unknown for centuries and only the advent of the space age could have EVER have sussed it out due to the fact that no earth bound telescope could have discovered it because the atmosphere blocks those bands of IR.
