This pair of images represents the same viewpoint on Earth through two different sets of filters on the MESSENGER spacecraft. On top, three filters in red, green, and blue wavelengths were combined to make an image that approximates what the human eye would see. The green mass at the center is the Amazon jungle of South America. The deserts of West Africa are just visible on the edge of the Earth's disk below and to the right of South America. The bottom image is "pushed" into the near infrared; instead of red, green, and blue, it is composed of images taken through near-infrared, red, and green filters. Chlorophyll, the green pigment in plant leaves, is very strongly reflective at near infrared wavelengths, much more so than it is in red or green wavelengths, so the vegetated parts of Earth burst into bright red color.
