brindafella writes: Look out, Stonehenge, here come the Wurdi Youang rocks in the Australian state of Victoria. A semi-circle of stones as been checked by an astrophysicist from Australia's premier research group, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), who says this arrangement of rocks is a carefully aligned solar observatory that may be 10,000 years old. It would have been created by local Aborigines, the Wathaurong people, who have occupied the area for some 25,000 years.
