BOSTON, March 4 (UPI) -- Boston University researchers have discovered the remnants of the largest crater of the Great Sahara of North Africa.
The crater may have been created by the impact of a meteorite tens of millions of years ago, said Dr. Farouk El-Baz.

El-Baz made the discovery while studying satellite images of the Western Desert of Egypt with his colleague, Dr. Eman Ghoneim of Boston University Center for Remote Sensing.
The double-ringed crater, which has an outer rim surrounding an inner ring, is approximately 19 miles in diameter.
El-Baz named his find "Kebira" -- which means "large" in Arabic and also relates to the crater's physical location on the northern tip of the Gilf Kebir region in southwestern Egypt.
