Caption:

This three dimensional effect is created by superimposing images of Jupiter's icy moon, Europa, which were taken from slightly different perspectives. When viewed through red (left eye) and blue (right eye) filters, this product, a stereo anaglyph, shows variations in height of surface features.

This view shows the rim and interior of the impact crater Mannann'an, on Jupiter's moon Europa. The stereo image reveals the rim of the crater which appears as a tall ridge near the left edge of the image, as well as and numerous small hills on the bottom of the crater. One of the most striking features is the large pit surrounded by circular cracks on the right side of the image, with dark radiating fractures in its center.

The right (blue) image is a high resolution image (20 meters per picture element) taken through a clear filter. The left (red) image is composed of lower resolution (80 meters per picture element) color images taken through violet, green, and near-infrared filters and averaged to approximate an unfiltered view.

North is to the top of the picture and the sun illuminates the scene from the east (right). The image, centered at 3 degrees north latitude and 120 degrees west longitude, covers an area approximately 18 by 4 kilometers (11 by 2.5 miles). The finest details that can be discerned in this picture are about 40 meters (44 yards) across. The images were taken on March 29th, 1998 at 13 hours, 17 minutes, 29 seconds Universal Time at a range of 1934 kilometers by the Solid State Imaging (SSI) system on NASA's Galileo spacecraft.
