For the first time, astroarchaeologists have statistically proven that the earliest standing stone monuments of Britain — the great circles — were constructed specifically in line with the movements of the Sun and Moon, 5000 years ago. University of Adelaide researchers used innovative 2-D and 3-D technology to test the patterns of alignment in the standing stones.

Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago. They suggest that the long, narrow entrance passages to ancient stone tombs may have enhanced their view of the night sky, enabling them to detect the first appearance of seasonal stars during twilight.
