The detection of cosmic rays is rare – however the latest detection is even rarer as it appears to be going in the wrong direction.
Cosmic rays are bombarding the Earth every day and are measured at observing sites across the world, with the most notable being located at the Earths south pole.
Not to be fooled by their historical name, cosmic rays generally refer to high energy particles with mass whereas high energy in the form of gamma rays and/or X-rays are photons. These cosmic particles were discovered in 1912 by Victor Hess when he ascended to 5,300 meters above sea level in a hot air balloon and detected significantly increased levels of ionization in the atmosphere.
