Mysterious 'Ghostly' Image Haunts Astronaut on Space Station
An astronaut aboard the International Space Station captured photos of a skull-like formation in the Tibesti Mountains in Chad. The images show a deep volcanic pit and soda lake called Trou au Natron, which resembles a ghostly face. The eye sockets and nose are actually cinder cones, while the white material is a mineral crust made of natron salt. The remote location of the area has made it difficult for scientists to study, but research suggests it was once a glacial lake. NASA also recently released images of an "eerie face" captured by the Juno space probe passing Jupiter.
