Two of Saturn's smaller moons have puzzled experts for some time due to their unusual shape.
At only 20 miles across the moons of Pan and Atlas are shaped more like a flying saucer than a conventional moon, but now scientists think they may have the answer after studying years worth of cosmic images.
They realised that 14 of Saturn's small moons had a very low density - about half that of water ice - and shapes that suggested they had grown out of the rings themselves. However, they would have needed a jump start as it is not gravitationally possible for small particles to fuse together within the rings.
