The discovery that the Moon has a tenuous atmosphere composed primarily of helium was made by LACE (Lunar Atmosphere Composition Experiment) a mass spectrometer used by the Apollo 17 mission in 1972, and these days the NASA's Lunar Reconnaissance Orbiter confirmed the discovery.

It is not yet clear whether the helium is originate from inside the Moon or from an external source like the solar wind or is just "captured" by the Lunar gravity, but in anyway this is another discovery about the Earth natural satellite confirmed in the last days.

An article published at NBCNEWS explain the report with more details. You can read the entire article HERE.
