The undated photo provided by University of Stuttgart shows an ancient Buddhist statue that a Nazi expedition brought back from Tibet shortly before World War II. The statue was carved from a meteorite which crashed on Earth thousands of years ago. Elmar Buchner of the University of Stuttgart told The Associated Press that the existence of the statue known as "iron man" was only revealed in 2007 when its owner died and it came up for auction.
