SUMMARY: Why does Iapetus have a dark side and bright side? That's a mystery scientists hope that the Cassini spacecraft will be able to solve as it spends the next few years orbiting the Saturnian system. The unusual light/dark nature of the moon was first revealed when the Voyager spacecraft swept past the moon more than 20 years ago. One theory is that the moon was coated by some other foreign material, but only on one side. Another idea is that it's being resurfaced from material inside the moon. This image was taken when Cassini was 3 million kilometres (1.8 million miles) away.

What do you think about this story? Post your comments below.

If I recall correctly, Iapetus was a pretty important moon in 2001: A Space Odyssey. Spoooooooky.

How close is Cassini likely to get to our black and white moon?

It will make a close pass in January.
