Lunar Eclipse Mosaic
Originally uploaded by gavin.jackson
A Mosaic created from the photos that Jo took of the lunar eclipse on 28 August 2007. A friend of mine Gene, posted the following description on his excellent photo (http://www.flickr.com/photos/ewahrlich/1257513746/): "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."
