The Tien Shan mountain range is one of the largest continuous mountain ranges in the world, extending approximately 1,550 miles (2,500 kilometers) roughly east-west across Central Asia. This image taken by the Expedition 27 crew aboard the International Space Station provides a view of the central Tien Shan, about 40 miles (64 kilometers) east of where the borders of China, Kyrgyzstan, and Kazakhstan meet.
