UPDATED: THE MOON ONCE HAD AN ATMOSPHERE

Hey Space Placers!

UPDATE: Today's  NASA Press Release  on this new finding.

Here is research that shows that our Moon once had an atmosphere due to volcanic activity that took place billions of years ago. It is thought that this atmosphere would have lasted 70 million years before finally being lost to space.

This lunar atmosphere would have been 1.5 times thicker than the current atmosphere on Mars. Calculations show that a water volume twice that of Lake Tahoe could have been released into the lunar atmosphere. The water at the Moon's poles could have been deposited during this era.
