Moon Causing Rainbow Reflection with Jupiter

Click Image for Larger Version

I was up really late because I was trying to photograph the comet that was up, but I couldn't find it. As I was packing up to leave, I saw the Moon and the rainbow through the clouds below it. I snapped several shots of it, and I think this is the most representative because it also has Jupiter (the bright point) to the upper right.

The rainbow is caused by very small water dropplets that are nearly perfect spheres. Because of this, they act as tiny lenses that refract the light, just the way the Sun can cause a rainbow around a light rain.
