This image provided by NASA on Thursday, April 26, 2012 shows lava flows in the shape of coils located near the equatorial region of Mars. Analyzing high-resolution images of the region, researchers have determined the area was sculpted by volcanic activity in the recent geologic past. This is the first time such geologic features have been discovered outside of Earth. (AP Photo/NASA)
