As seen on the National Geographic News this lunar eclipse sequence is obtained during two hours of 2008 Feb. 20 evening with single shots every few minutes. The red colouring arises because sunlight reaching the Moon must pass through a long and dense layer of the Earth’s atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate. This resulting light we perceive as red. The foreground in this image is Lumby in British Columbia, Canada.
