Here’s another great image from Astronomy Picture of the Day. Mercury is a rather drab planet, without a whole lot of color variation. By using computers to enhance this image taken by the Messenger probe as it flew by Mercury in January, features of various compositions stand out much more clearly. The colors are no longer natural, but the images become much more valuable for scientific interpretation. The small, bright orange areas, for example, may indicate rocks of volcanic origin.
