Above, a stunning photo of a little known moon of Saturn, only 30 kilometers across. It's called "Pan." The soon to self-destruct Cassini orbiter took the picture last week.

Why the heck does it look like that? Who knows? Only a small number of craters are visible. That indicates that the surface is fairly new, but how could that be?

For comparison here's (above) Mimas, also a moon of Saturn. Mimas is eleven times larger than Pan, and the surface is quite a bit older and strewn with craters. If the left side is dark, drag your cursor over it to light it up.

self-healing surface -- just like those cutting mats.
