Also known as the Eye of the Sahara, this hypnotizing formation can be found in the desert of western Mauritania. Dutch Astronaut Andre Kuipers took this photo from the International Space station. Although no one is exactly sure of its origin, it was initially interpreted as an asteroid impact structure because of its high degree of circularity. Today, however, it is speculated to be a highly symmetrical and deeply eroded geologic dome.
