Composite image of Jupiter's moon Europa taken by the Solid State Imaging (SSI) instrument of NASA's Galileo mission. The images have been re-processed to show a colour view of the surface that approximates how Europa would appear to the human eye. The diversity of Europa's surface geology is evident. Long, linear cracks and ridges crisscross the surface, interrupted by regions of disrupted terrain where the surface ice crust has been broken up and re-frozen into new patterns. Colour variations across the surface are associated with differences in geologic feature type and location. For example, areas that appear blue or white contain relatively pure water ice, while reddish and brownish areas include non-ice components in higher concentrations. The polar regions, at left and right, are noticeably bluer than the more equatorial latitudes, which look more white. This colour variation is thought to be due to differences in ice grain size in the two locations. Images taken through near-infrared, green and violet filters have been combined and colour corrected. Gaps in the images have been filled with simulated colour based on the colour of nearby surface areas with similar terrain types. The original images were taken in 1995 and 1998. Scale is 1.6 kilometres per pixel and the right hand side of the image is North.
