Europa's terminator

This image of Europa was obtained by the Solid State Imaging (CCD) System on board NASA's Galileo spacecraft during its 4th orbit of Jupiter. Linear features with bright central stripes referred to as "Triple Bands" (TB) are seen to transect the surface of Europa. Several of these TBs are over 700 Km in length. In the left side of the image the surface of Europa is seen to be locally pitted and irregular. Ridges less than 100 Km in length are also visible in this Region.
The area seen in this image, centered near 27° South and 300° West, is 760 (456 miles) by 850 Km (510 miles) across, which is approximately the size of the state of Texas or the country of France. North is to the top of the image, with the sun illuminating the surface from the left. The image which has a resolution of 1,3 Km per picture element (e cioè "per pixel") was obtained on December, 19th, 1996.
