Problem:Nasa has released a series of photos taken from space of the desert in Kazakhstan, in a bid to help unlock the secrets of a prehistoric settlement. 
  
 The site in the Turgai region of northern Kazakhstan is unremarkable from the ground: a vast empty steppe, with little evidence of human habitation. But seen from 430 miles above ground, the 8,000-year-old shapes begin to take the form of man-made constructions. 
  
 The photos show at least 260 different earthworks — mounds, trenches and ramparts — which make up five basic shapes; among them a circle and a swastika. When the images were first spotted in 2007, on Google Earth, wild rumours circulated that the sites were designed by Nazis or even aliens. 
  
 “ I was worried this was a hoax ,” said Ronald LaPorte, an emeritus professor of epidemiology at Pittsburgh who noticed a report about the findings last year, while researching diseases in Kazakhstan. 
  
 But he became increasingly fascinated by the findings, and determined to speak to Dmitriy Dey, the Kazakh geologist who first spotted the site after watching a documentary about ancient sites, and wondering whether his own country had such areas. 
  
 In 2013 scientists found a mysterious pentagram symbol in Kazakhstan - sparking speculation that it was something to do with a cult. But it is now believed to have been created as a Soviet theme park, long since abandoned. 
  
 The Turgai site, however, has been far more complex to fathom. 
  
 The two men worked to publicise the find, and enlist the help of Nasa.

 “I’ve never seen anything like this; I found it remarkable,” said Compton Tucker, a senior biospheric scientist for Nasa in Washington who provided the archived images, taken by the satellite contractor DigitalGlobe, to Mr Dey and The New York Times. 
  
 It is now hoped that the detailed images will enable greater research into the site. 
  
 Mr Dey said he does not think they were ever intended to be seen from the air. Instead he believes that the figures built along straight lines on elevations were “horizontal observatories to track the movements of the rising sun.” 
  
 His research suggests that the Mahandzhar culture, a Stone Age tribe living in the region from 7,000 BC to 5,000 BC, could have created some of the the older structures.

 But scientists have been surprised by the idea that a nomadic population would have stayed in one place for the time required to fell and lay timber for ramparts, and to dig out lake bed sediments to construct the huge mounds - originally six to 10 feet high, and now three feet high and nearly 40 feet across. 
  
 “The idea that foragers could amass the numbers of people necessary to undertake large-scale projects — like creating the Kazakhstan geoglyphs — has caused archaeologists to deeply rethink the nature and timing of sophisticated large-scale human organization as one that predates settled and civilized societies,” said Persis Clarkson, an archaeologist at the University of Winnipeg, who viewed some of Mr Dey’s images. 
  
 “Everything is linked through the cult of the sun,” Mr Dey told The New York Times. 
  
 He now hopes to create an operations centre at the site, for further research. 
  
 “We cannot dig up all the mounds. That would be counterproductive,” he said. “We need modern technologies, like they have in the West.” ||||| NASA is best known for solving the mysteries of space, millions of miles from our home planet. It’s now joined the investigation into some very strange and very old earthbound formations in northern Kazakhstan, the New York Times reported (paywall). 
  
 These huge formations—called the Steppe Geoglyphs—were first discovered on Google Earth by Dmitriy Dey, an amateur archaeologist, in 2007. Since then, Dey has found about 260 of the land designs—which resemble crop circles, but are much stranger. 
  
 Archaeologists don’t know what they are or who built them, but they estimate that the oldest is 8,000 years old.

 Dey’s research was apparently convincing enough to persuade NASA to help figure out what these things are. NASA’s satellite images (taken by contracter DigitalGlobe) of the formations are the first time they’ve been photographed from space. 
  
 NASA has also directed the astronauts on the International Space Station to start photographing the region, so perhaps look out for new photos on Scott Kelly’s Instagram in the coming weeks. 
  
 The geoglyphs—formed by man-made mounds, divots, trenches, and banks—come in a variety of shapes. 
  
 One of them, called the Bestamskoe Ring, is a circle made up of dozens of smaller circles. Another, named Ushtogaysky Square, is 810,000 square feet—each 900-foot side is as long as an aircraft carrier—with an X-shape through the middle. The weirdest of all, though, is the Turgai Swastika, which, you guessed it, resembles a swastika. (The swastika was a popular symbol long, long before the Nazis appropriated it.)

 Thousands of years ago, the northern region of Kazakhstan offered rich hunting grounds for nomadic Stone Age tribes. (Ushtogaysky Square, the largest of the formations, sits close to a known Neolithic settlement.) The problem is, the formations would have taken far longer to build than how long historians currently believe these tribes stayed in one place. 
  
 “The idea that foragers could amass the numbers of people necessary to undertake large-scale projects—like creating the Kazakhstan geoglyphs—has caused archaeologists to deeply rethink the nature and timing of sophisticated large-scale human organization as one that predates settled and civilized societies,” Persis B. Clarkson, an archaeologist at the University of Winnipeg, told the Times. 
  
 Dey dismisses theories that aliens are behind them—he believes the elevated straight lines on the geoglyphs were “horizontal observatories to track the movements of the rising sun.” 
  
 That would make them a close cousin to structures like Stonehenge, and the recently discovered “Superhenge,” which scientists also theorize may have been sun-related. ||||| High in the skies over Kazakhstan, space-age technology has revealed an ancient mystery on the ground. 
  
 Satellite pictures of a remote and treeless northern steppe reveal colossal earthworks — geometric figures of squares, crosses, lines and rings the size of several football fields, recognizable only from the air and the oldest estimated at 8,000 years old. 
  
 The largest, near a Neolithic settlement, is a giant square of 101 raised mounds, its opposite corners connected by a diagonal cross, covering more terrain than the Great Pyramid of Cheops. Another is a kind of three-limbed swastika, its arms ending in zigzags bent counterclockwise. 
  
 Described last year at an archaeology conference in Istanbul as unique and previously unstudied, the earthworks, in the Turgai region of northern Kazakhstan, now number at least 260 — mounds, trenches and ramparts — arrayed in five basic shapes. |||||
Solution:
Archaeology enthusiast Dmitriy Dey was watching a television program on pyramids when he decided such things should exist in his native Kazakhstan, as well. The New York Times reports he hopped onto Google Earth to look around a little and stumbled across what could prove to be the oldest earthworks ever discovered. Two weeks ago—eight years after Dey made his discovery—NASA released the first satellite images of the 260 or so mounds, banks, and trenches that populate a remote area of the country. According to Quartz, the largest of these man-made geometric figures is called the Ushtogaysky Square. It's 810,000 square feet with each side measuring as long as an aircraft carrier. “I’ve never seen anything like this," one NASA scientist tells the Times. "I found it remarkable." Kazakhstan has shown little interest in studying what are now called the Steppe Geoglyphs since Dey discovered them in 2007, the Times reports. In fact, so little had been published about the discovery that a professor looking into them thought they must be a hoax, according to the Telegraph. That's starting to change. The Times reports initial research into the earthworks reveals the oldest to be about 8,000 years old. If that's true, it would be the oldest ever found. Dey believes they could have been built by Stone Age tribes living in the region, which would challenge scientific assumptions on early nomadic peoples. Tribes would have to have been larger, better organized, and more stationary than previously thought. Dey is now hoping to set up a base from which to study the geoglyphs, and NASA has requested photos of the area from astronauts. (One geoglyph found in Kazakhstan is in the shape of a swastika.)
