Outgassing of a Lunar Atmosphere

The atmosphere of the Moon may come from a couple of sources, one source is outgassing or the release of gases such as radon, which originate deep inside the Moon.

Gases are released from the interior of the Moon during moonquakes. Certain elements are radioactive which means that over time, these elements decay and change into new elements. These elements form a kind of "time machine" that scientists can use to determine what happened on the Moon in the past.

Compared to the Earth, the Moon's surface is inactive, however moonquakes do occur, usually originating in the region between the crust of the Moon and the Moon's core. By measuring outgassing events by special detectors researchers may be able to discover information about the character and frequency of that tectonic activity.
