Red vs. Blue
This enhanced-color scene lies on the edge of Praxiteles, a peak-ring basin approximately 200 km in diameter. The high-reflectance, redder areas are irregularly shaped pits likely formed by volcanic activity, and the high-reflectance, bluer areas are hollows. Pits and hollows are often found together on Mercury. Their relationship to one another is the subject of ongoing investigation by the MESSENGER team.
