"Hollows" in Raditladi Basin on Mercury. Image with strengthened colors by MESSENGER; width is 7 km. "Description from NASA photojournal": View of a section of the floor and peak-ring mountains of the Raditladi impact basin, including the area in a previous Gallery image. The individual frames in the mosaic are about 20 km wide. The rounded, depressions, called "hollows" are a fascinating discovery of MESSENGER's orbital mission and may have been formed by sublimation of a component of the material when exposed by the Raditladi impact. This image was created by merging high-resolution monochrome images from MESSENGER's Narrow Angle Camera with a lower-resolution enhanced-color image obtained by the Wide Angle Camera.
