The national space agency has been officially probing into these unusual land designs, which had been first discovered in 2007.
NASA has captured some of the stunning images of massive mysterious earthworks in the remote northern area of Kazakhstan.

Geometric figures of square, crosses, lines and rings, covering the size of many football fields, have been taken from very high in the skies, around 430 miles up and they look incredible indeed.
The mysterious land designs or what they call Steppe Geoglyphs were first discovered in 2007 by a local archeological enthusiast Dmitriy Dey. The amateur archeologist searched Google Earth images of Kostanay city. He found a giant square, more than 900 feet on each side, made up of dots, crisscrossed by a dotted X and went on to discover one after another similar mysterious figures. Around 260 earthworks have been spotted ever since and some of them are estimated at 8,000 years old.
But scientists are puzzled over these gigantic earthworks even a long time has gone by. They confess it is something of a head-scratcher.
“I’ve never seen anything like this; I found it remarkable.” Compton J. Tucker, a senior biospheric scientist for NASA in Washington told The New York Times.
To solve the mystery, NASA has officially joined the investigation a few weeks ago and directed astronauts in International Space Station (ISS) to take images of the region from the space.
There are many theories about who, why and how these mysterious earthworks had been created. Dmitriy Dey theorizes that a colossal earthwork called Turgai Swastika has such kind of pattern that is designed to “track the movements of the rising sun.” He further suggests that that the Mahandzhar culture, which flourished there from 7,000 B.C. to 5,000 B.C., could be linked to these figures. But scientists are perplexed by the idea that this nomadic population could stayed for that much long time to construct the huge mounds, which were originally 6 to 10 feet high and now 3 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.” Persis B. Clarkson, an archaeologist at the University of Winnipeg, who viewed some of the images, explained.

With no genetic material to analyze, NASA’s space photography may help unlock the mystery and may mobilize support for further research.
