This view of Cilix impact crater on Europa was created in 2013 using 3-D stereo images taken by NASA’s Galileo spacecraft, combined with advanced image processing techniques. The crater has a diameter of about 11 miles (18 kilometers). This image, which combines a 3-D Digital Elevation Model, or DEM, with original imagery, shows that the […]
Cracks and Ridges on Europa
This enhanced color image shows cracks and ridges on Europa’s surface that reveal a detailed geologic history. Some ridges, such as the prominent one at top right, develop into long, arc-shaped “cycloids” that may be related to changing tidal forces as Europa orbits Jupiter. The wall of this ridge stands perhaps a third of a […]
