Astronauts know it as "the eye of the desert" and it is also called the heart of the feathers, and it is located in the Sahara Desert in northern Mauritania.
There is scientific controversy about its nature, as some scientists say that it is a crater caused by a meteorite that struck that area, and some say that it is an ancient dormant volcano.
They are circular-shaped craters with a huge diameter of 35 km, surrounded by a blue aura similar to the pupil of the eye that can be seen from outer space, where the surrounding rock formations appear in the form of an eyelid, from which the name came.
It was discovered by a French researcher, Theodore Mono, in the thirties of the twentieth century, and since then, geological expeditions have been coming to that area to study its nature and try to find a scientific explanation for it.
