Hey Space Placers!

As promised yesterday here is the newest theory on how the Moon formed. 

Previously the leading theory was that the Moon formed as the result of a Mars-sized object called Theia impacting the Earth.

In this new theory the Earth has been vaporized due to a huge impact forming a Synestia - a hypothesized structure that forms - and the Moon emerges shortly afterwards followed by the Earth reforming.

This is a very intriguing, and to me, very plausible theory. More computer modeling and analysis of the Apollo lunar samples, including hopefully a new sample box - see yesterday's blog - will provide further refinement, and maybe, just maybe, a way to confirm how Luna came to be.
