There have been some new findings about our Moon released recently.
The results have come from NASA's GRAIL mission that flew two identical spacecraft, named Ebb and Flow, in perfect tandem for the past year to study the interior composition of the Moon.
GRAIL has gathered data that has been used to make the most detailed gravity maps of the Moon which in turn allow scientists to discern what the interior of the Moon is like. See more at http://svs.gsfc.nasa.gov/vis/a000000/a004000/a004014/.
GRAIL's Ebb and Flow are set to fly into a lunar mountain on December 17. I'll have more on that tomorrow.
