Freckles on Europa?The surface of Europa shows many signs that there may be an ocean under it's icy surface. In this picture, the dimples, shown in red, may be a sign of material falling into a water under the ice. Or they be caused by material rising up from moving water underneath. Other signs of an ocean under the surface of Europa include: * flooded areas * rafting * 'mushy' craters, and * areas of spreading.
