An investigation by the Dutch national museum has revealed that one of its prized possessions, a rock supposedly brought back from the moon by Apollo 11 astronauts, is nothing more than a lump of petrified wood. The rock was originally given to former Prime Minister Willem Drees by then-U.S. ambassador J. William Middendorf during a visit by the astronauts shortly after their 1969 moon landing. A spokesperson said the museum will keep the piece anyway, as a curiosity. More at BBC News.
