Have You Ever Seen a Moonbow?

[/caption] They are elusive, but powerful to see. "Moonbows" are rainbows created by light from the Moon. Conditions have to be just right, and there are only a small number of places in the world where they regularly materialize, such as Victoria Falls on the border between Zambia and Zimbabwe as seen above, Cumberland Falls in Kentucky, Yosemite Falls in California, and Waimea on Hawaii. Because they are so faint, moonbows are difficult to see with the naked eye (they usually appear just white). But with long-exposure photography, all the colors of moonbows can be seen. Below, check out a gorgeous video of stars, a moonbow and rainbow over Torres del Paine in Patagonia, Chile, and more moonbow images at
