People used to think that moons such as the Earth's moon or the moons of Jupiter had no atmosphere whatsoever. Now, however, measurements have shown that most of these moons are surrounded by a *very* thin region of molecules which can *almost* be called an atmosphere. Such is the case with the Moon.
The elements sodium (Na) and potassium (K) have been detected using Earth-based spectroscopic methods, whereas the element radon-222 and polonium-210 have been inferred from data obtained by the Lunar Prospector alpha particle spectrometer.[2] Argon-40, helium-4, oxygen and/or methane (CH4), nitrogen gas (N2) and/or carbon monoxide (CO), and carbon dioxide (CO2) were detected by in-suit detectors placed by the Apollo astronauts.[3]
Although lunar volcanism was supposed to have ceased billions of years ago, there's at least one place on the Moon where "outgassing" may have happened within the past 10 million years--and may still be happening today (Schultz, Staid and Pieters, Nature, 444, 184).

Are you familiar with Bart Sibrel's films and ideas, i.e. that the moon landings were faked? ... Has Richard Hoagland, with his pictures of backround structures in the astronaut photos of the moon, provided the "extraordinary proof" necessary to sustain Sibrel's extraordinary claim?
It is interesting to note that while claiming that the moon has no atmosphere, Hoagland shows a photo that shows sunset-like light dispersion, similar to the atmospheric effect seen on earth. He didn't account for it in the video. I was wondering what his explanation would be.

After a few minutes of observation and cogitation I realized that what made that blackened portion of the moon a little lighter than the black backround of space was earthlight. Just as the earth can be bathed in moonlight, the moon can be bathed in earthlight! That is what enables us to observe the occluded portion of the moon during various phases.
"The recent Fox TV show, which I saw, is an ingenious and entertaining assemblage of nonsense. The claim that radiation exposure during the Apollo missions would have been fatal to the astronauts is only one example of such nonsense." -- Dr. James Van Allen

However I noticed something else. Around the edge of the occluded portion of the moon there was a ring of faint light, just slightly brighter than the surface of the occluded portion. I wondered what could be the cause of this faint ring of light circling the globe of the moon. It finally came to me in a flash. The moon must have an atmosphere!
The effect on the moon was first noticed in 1968, when NASA's Surveyor 7 lander photographed a strange glow on the horizon after dark. Nobody knew what it was. Now scientists think it was sunlight scattered by electrically charged moon dust floating just above the surface.
