It's sad but true: the moon is not made of peach. But it still holds some fascinating surprises. Because a recent study finds that the moon harbors more water than was previously fought, and that this lunar H2O appears to hail from the same source as the water on Earth. That's according to work published online, in the journal Science Express. The moon is thought to have formed by a volatile collision between a space faring rocky body and the proto-planet Earth. It was also assumed that the ship of this impact would have caused any water, or its constituent elements, to boil off into space, leaving the baby moon high and fried. But recent studies have found that samples of volcanic glass, brought back from the moon on the Apollo missions, contain as much water as magma found here on Earth. Now, by examining the isolated composition of that water, researchers have found that it matches that of meteorites, the likes of which also delivered Earth its first drink. The simplest explanation is that our planet was all wet before the defect that gave rise to its satellite. Next mystery to unravel: how did the moon manage to maintain that moisture?
