This area contains furrows of several orientations. In some cases the furrows cross-cut one another. There are also intervening patches of dark smooth material, which might be volcanic in origin. High resolution pictures of Galileo Regio terrain will be analyzed with respect to relations between furrows, the region's dark materials, and the partially filled-in crater. Fine Details Dramatic view of fine details in ice hills and valleys in an unnamed region on Jupiter's moon Ganymede.
North is to the top of the picture and the sun illuminates the surface from the left.
In the right hand version the processing has been changed to bring out details in the shadowed regions that are illuminated by the bright hillsides. The brightness of some of the hillsides is so high that the picture elements 'spill over' down the columns of the picture. Fracturing Two highly fractured craters are visible in this high resolution image of Jupiter's moon, Ganymede. NASA's Galileo spacecraft imaged this region as it passed Ganymede during its second orbit through the Jovian system.
