Archeologists working high in the Peruvian Andes have discovered the oldest known celestial observatory in the Americas - a 4,200-year-old structure marking the summer and winter solstices. The observatory was built on the top of a 33-foot-tall pyramid with precise alignments and sightlines that provide an astronomical calendar for agriculture, archaeologist Robert Benfer of the University of Missouri said.
