High-res version

In the deep deserts of the Sahara there is one location that stands out from the rest of the rather featureless desert, the Richat Structure.

Looking almost like an eye or a bulls-eye the Richat structure has a diameter of approximately 50 kilometers and is located 400-450 meters above sea level. Ever since the earliest space missions it has attracted astronauts to peek down as it’s such a beautiful landmark.

Researchers first thought it was a meteorite impact structure because its high degree of circularity but it is now thought to be a symmetrical uplift which has been laid bare by erosion.
