The mottled appearance results from chaotic areas where the bright, icy crust has broken apart to expose a darker material underneath. North is to the top of the image, and the Sun illuminates the scene from the right. The images were taken on Nov. 6. The smooth gray band at the lower part of image represents a zone where the Europan crust has been fractured, separated, and filled in with material from the interior. The chaotic terrain and the gray band show that Europa has been subjected to intense geological deformation. The mosaic is centered at 2.9 degrees south latitude and 234.1 degrees west longitude and covers an area of 261 kilometers by 168 kilometers (159 miles by 102 miles). The smallest distinguishable features in the image are about 229 meters (751 feet) across. These images were obtained on Nov. 6, 1997, when the Galileo spacecraft was approximately 21,700 kilometers (about 13,240 miles) from Europa. The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC. JPL is a division of California Institute of Technology.
