This infrared image of the Earth was taken by the GOES 6 satellite on September 21, 1986. A temperature threshold was used to isolate the clouds. The land and sea were separated and then the clouds, land and sea were separately colored and combined back together to produce this image. (Courtesy Rick Kohrs)
