This is a photograph taken by Wally Pacholka of Mars with a colorful lunar fog bow. This photograph itself is strikingly beautiful and looks like a dream land. Last week Mars reached opposition, which is when Mars and Earth are closest together in their orbits. This causes Mars to be the brightest part of the photograph. The fog bow itself is apparently very rare. A normal rainbow is created by sunlight reflected by falling raining, however this fog bow was created by moonlight reflected by small water drops in fog. The fog itself appears white, however all of the colors of the rainbow can be located. This photo was taken in Haleakala, Hawaii. =)
