Thera and Thrace
To produce this image, two regional images obtained at a resolution of 220 meters per picture element during Galileo's 17th orbit of Jupiter were colorized with lower resolution (1.4 kilometers per picture element) images of the region obtained during the 14th orbit. The color image is generated from the violet, green, and near-infrared (968 nanometers) filters of the Galileo Solid State Imaging system and exaggerates the subtle color differences of Europa's surface. The mosaic, centered at about 50 degrees south latitude and 180 degrees longitude, covers an area approximately 525 by 300 kilometers. The images from the 17th orbit were acquired on September 26, 1998 when the sun illuminated the region from the northeast.
