This is a way cool article! "An ancient astronomical alignment in southern Peru has been discovered by researchers between a pyramid, two stone lines and the setting sun during the winter solstice. During the solstice, hundreds of years ago, the three would have lined up to frame the pyramid in light." This only renews my former interest in Peruvian astronomy. http://www.nbcnews.com/id/51791257/ns/technology_and_science-science/t/stunn... Tom Sevcik
