Egyptian crop circles from the International Space Station

An astronaut aboard the International Space Station captured the circular farming patterns in Sharq El Owainat for NASA’s Earth Observatory. “The remote agricultural outpost in the Sahara Desert lies approximately 290 kilometers (180 miles) from the nearest city and 210 kilometers (130 miles) from the Toshka lakes. The Nubian Sandstone Aquifer System, buried beneath the sand, allows patches of agriculture to survive in the middle of the desert.” No, these crop circles are not the work of aliens or some mysterious force, they are “a result of center-pivot irrigation, an efficient method for water conservation in agriculture. Groundwater from the Nubian aquifer is drawn up from wells in the center of the circles, and it is sprayed or dripped out of long, rotating pipes that pivot around the center.”
