The Eye of the Sahara: A Mystery Older than Humans

Known as the Richat Structure, the Eye of the Sahara is one of the most interesting and impressive geological formations. It is in the Sahara Desert, stretches for 40 km, and looks like a bullseye. The eye is so huge that it can be seen from space and astronauts use it as a visual landmark. It was first photographed by Gemini Project astronauts in the 1960s.

Initially, geologists believed that the Eye of the Sahara was the result of a meteor crash. They thought that the crater in its middle must have been the work of an object from space falling with an immense speed. However, experts later realized that the Eye was all naturally formed making it even more extraordinary.
