It's sad but true: the moon is not made of cheese. But it still holds some fascinating surprises. Because a recent study finds that the moon harbors more water than was previously thought, 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.
这是悲哀但真实的事实：月球并不是由奶酪构成的h3%4g..O2irx。不过月球上仍然充满着意想不到的惊喜~j0mOby,&3QdhW。因为近期一项研究发现，月球上蕴含的水分比之前想象的要多，且月球上的水似乎与地球上的水来源相同h8qRhHaxRv。这项研究发表在《科学快讯》杂志官网上~TK0;f6FxF]^。

The moon is thought to have formed by a violent collision between a spacefaring rocky body and the proto-planet Earth. It was also assumed that the heat of this impact would have caused any water, or its constituent elements, to boil off into space, leaving the baby moon high and dry.
关于月球的形成有一个假设：飞行的岩石行星剧烈地撞击原始地球从而形成了月球]QFN]&lLwJ1-N&h,+。还有一种假设：这种撞击产生的热能导致水（月球的组成元素）汽化后进入太空，留下干燥的月球高高悬挂在天上ALV]-z|g[A。
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 isotopic 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 impact that gave rise to its satellite. Next mystery to unravel: how did the moon manage to maintain that moisture?
对这个现象最简单的解释是：我们的星球在与行星撞击形成月球之前就有了水TF])H3=|mab_8。下一个待解之谜：月球如何设法保住了水分？
