Scientists say new examinations of soil collected on the moon suggest its atmosphere might have been created by repeated meteorite strikes.
Researchers studying the moon first used instruments to confirm it had an atmosphere in the early 1970s. The American space agency NASA explains the moon’s atmosphere is “very thin and weak.” It is technically considered an “exosphere.”
The newly examined soil was collected by NASA astronauts during America’s Apollo program from 1969 to 1972. The trips resulted in astronauts capturing about 382 kilograms of rocks and soil, called samples.
Instead of attempting to measure the moon’s atmosphere in a direct way, investigators looked to the old soil material.…
