ဖိုင်:Moon's shadow in muons.gif

An image of the shadow of the Moon in muons as produced by the 700m subterranean Soudan 2 detector in the Soudan Underground Mine State Park in Minnesota. The shadow is the result of approximately 120 muons missing from a total of 33 million detected in Soudan 2 over its 10 years of operation. The cross denotes the actual location of the Moon. The shadow of the Moon is slightly offset from this location because cosmic rays are electrically charged particles and were slightly deflected by the Earth's magnetic field on their journey to the upper atmosphere. The shadow is produced due to the shielding effect the Moon has on galactic and cosmic rays, which stream in from all directions. The cosmic rays normally strike atoms high in the upper atmosphere, producing showers of muons and other short lived particles.
