Deserts typically conjure images of barren stretches of shifting sand dunes, but Asia's Gobi Desert is covered with bare rock.

The Gobi, which is about 1,600 kilometers (990 miles) in extent from east to west and about 1,000 km (620 miles) from north to south, has a total area of 1,300,000 square km (800,000 square miles), making it the largest desert in Asia and the fourth largest in the world. The desert stretches across vast areas of the Mongolian People's Republic and the Inner Mongolian Autonomous Region of China.

The name "Gobi" means "waterless place" in Mongolian. The desert receives 200 to 250 millimeters (8 to 10  inches) of rain along the northern and eastern edges, while its southeastern portion is completely waterless.

Small lakes that are kept filled by groundwater are visible in the image dotting the landscape. Archaeological evidence shows the lakes have existed for a very long time, with Stone Age dwellers living along their borders, the ESA statement said.

Numerous important fossils have been found in the Gobi Desert , including the first dinosaur eggs.
