Officially known by the rather prosaic name of the Richat Structure, this mysterious structure came to the attention of early space missions because of its out-of-place appearance in the middle of the Sahara desert.
This unique structure in the Sahara Desert of Mauritania can be seen from space. It is 50 miles wide and rather unusual for the fairly featureless Sahara. Though people often refer to it as an impact structure, it’s actually the natural result of hundreds of thousands of years of erosion. Formed from layers of sedimentary rock, fierce winds and shifting sand dunes have worn away at the material, leaving a crater impression behind. It is also known as the Eye of Africa
