Astronaut's Haunting Encounter: Giant Skull Gazes Back From Earth

An astronaut aboard the International Space Station captured a photo of a giant skull-shaped geological formation in Africa called Trou au Natron. The formation, located in Chad's Sahara desert, is a volcanic caldera with smoldering volcano cones that resemble the eyes of the skull. The area is remote and little is known about it due to its inaccessibility and political unrest. The formation is of interest to scientists who are studying its formation and history.
