Image of the Day: Ancient Mystery Earthworks So Massive NASA is Imaging Them From Space






During the past few years, archaeologists have revealed more than 200 massive Turgai, Kazakhstan earthworks, called Steppe Geoglyphs, or the Turgai Geoglyphs, so large they are not obvious from Earth. They were discovered by a Kazakh archaeologist browsing Google Earth in 2007. While clicking over the seemingly empty landscape, he saw remarkable patterns in the soil: crosses, boxes, swastikas, circles, and more, created from mounts of dirt only three feet high and roughly 30 feet wide. All in all, there are now 260 known geoglyphs that NASA has been imaging NASA since 2012.

According to the New York Times Ralph Blumenthal who talked with several NASA researchers, including University of Winnipeg’s Persis B. Clarkson, who imaged the huge structures the discoveries are forcing archaeologists to reconsider “the nature and timing of sophisticated large-scale human organization.”

NASA is not new to assisting archeologists: in the 1980s, a radar scan of Sudan helped archaeologists discover “ancient watercourses” via the Space Shuttle; in the 1990s, NASA and National Geographic collaborated to study aspects of Maya civilization using remote sensing technology.
