Astronomers have declared that the moon is shrinking after spotting wrinkles all over the lunar surface. The tell-tale contraction marks were discovered by US scientists who examined thousands of photographs of the moon's surface taken by a Nasa orbiter.
Some of the wrinkles are several miles long and rise tens of metres above the dusty terrain. Researchers believe they arise from the moon decreasing in size by around 200 metres across its diameter. The moon's mean diameter is generally calculated to be 2,159 miles.
