NASA sparks interest in enigmatic earthworks of Kazakhstan (PHOTOS, VIDEO)

ASTANA. KAZINFORM Archaeologists call them the Nazca lines of Kazakhstan - hundreds of giant geoglyphs formed with earthen mounds and timber found stretched across the landscape in northern Kazakhstan. They are designed in a variety of geometric shapes, including crosses, squares, rings, and even a swastika, a prehistoric symbol that has been in use for at least 12,000 years. Now NASA is helping to piece together this ancient landscape by using space-age technology to reveal more of the colossal earthworks, recognizable only from the air.

The New York Times reports that NASA released satellite photographs of some of the figures from about 430 miles (690 kms) up.

"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.

Around 50 geoglyphs were first spotted on Google Earth in 2007 - a number that has now reached 260 - but they have so far failed to draw significant funding for extensive research. NASA's interest in the geoglyphs may change this and help to mobilize support for further investigation.

Last year, a team of archaeologists from Kostanay University in Kazakhstan and Vilnius University in Lithuania investigated the giant structures using aerial photography and ground-penetrating radar. Their results revealed a wide variety of shapes ranging from 90 to 400 metres (295 to 1312 feet) in diameter, mostly made of earthen mounds, but one - the swastika - was made using timber. Researchers have not yet dated the structures but their characteristics suggest they are between 2,000 years and 8,000 years old.

Despite a plethora of research on these amazing creations around the world, the purpose of the geoglyphs continues to elude researchers and remains a matter of conjecture. Some scientists believe they are linked to the heavens with some representing constellations in the night sky. Other experts believe that the lines played a role in pilgrimage, with one walking across them to reach a sacred place. Yet another idea is that the lines are connected with water, something vital to life yet hard to get in the desert, and may have played a part in water-based rituals. Archaeological excavations at the Kazakhstan geoglyphs revealed the remains of structures and hearths, suggesting that rituals took place there.

The ancient earthworks are concentrated around the region of Turgai in Kazakhstan.
