Tyre Crater (False Colors; credits for the additional process. and color.: NASA/JPL)
This feature on Europa was seen as a dark, diffuse circular patch on a previous Galileo global image of Europa's Leading Hemisphere on April 3, 1997. The "bulls-eye" pattern appears to be a 140- Km-wide impact scar (about the size of the island of Hawaii) which formed as the surface fractured minutes after a mountain-sized asteroid or comet slammed into the satellite. This approx. 214-Km-wide picture is the product of 3 images which have been processed in false color to enhance shapes and compositions. North is toward the top of this picture, which is illuminated from sunlight coming from the West. This color composite reveals a sequence of events which have modified the surface of Europa. The earliest event was the impact which formed the Tyre structure at 34° North Latitude and 146,5° West Longitude. The impact was followed by the formation of the reddish lines superposed on Tyre. The red color designates areas that are probably a dirty water ice mixture. The fine blue-green lines crossing the region from west to east appear to be ridges which formed after the crater.
