Moon Younger than Previously Thought

The [news out of Denmark](http://news.ku.dk/all_news/2011/2010.8/moon-younger-than-we-thought/), where scientists there have gathered around a lunar rock brought back by Apollo 16, is that the moon is 200 million years younger than was previously thought. That moves the age of the moon up from 4.57 billion years to 4.36 billion years.

By the way, in case you were wondering, I have no idea how this impacts the theory that the moon is basically a big magma spitball shot out of the ocean of magma that was the Earth as the solar system was first forming — it got spit out when something else hit the Earth.

Apparently this puts the moon’s crust at relatively the same age as the Earth’s crust from around Australia.
