The Richat Structure is also known as the Eye of the Sahara. It’s a distinct and prominent circular geographical feature in the Sahara Desert. At roughly 30 miles wide, you probably wouldn’t notice that you were within it, but from an aerial view – and even from space – it is highly visible. Originally, it was thought to be the product of an asteroid impact and later people thought it could have been created by a volcanic eruption.
