Muons, once used to explore the inside of pyramids and volcanoes alike, are enabling researchers to see deep underground with a technological breakthrough from PNNL. Invisible to the naked eye, muons are elementary particles created by the collisions of cosmic rays with molecules in the atmosphere. Muons are constantly raining down on the earth at various angles. They can pass through materials, such as earth and rock, and detecting these particles have helped researchers “see” the inside of structures such as the pyramids of Giza...
