Cosmic ray

Cosmic ray flux versus particle energy
Pacini makes a measurement in 1910.
Increase of ionization with altitude as measured by Hess in 1912 (left) and by Kolhörster (right)
Hess lands after his balloon flight in 1912.

Cosmic rays are immensely high-energy radiation, mainly originating outside the Solar System. They may produce showers of secondary particles that penetrate and impact the Earth's atmosphere and sometimes even reach the surface. Composed primarily of high-energy protons and atomic nuclei, they are of mysterious origin. Data from the Fermi space telescope (2013) have been interpreted as evidence that a significant fraction of primary cosmic rays originate from the supernovae of massive stars. However, this is not thought to be their only source. Active galactic nuclei probably also produce cosmic rays.
