| cosmic rays |
are highly energetic electron-deficient atoms (mainly protons) which impinge equally upon the Earth from all directions. The average cosmic ray has an energy of 7 GeV. Cosmic ray electrons exist but they are only one hundredth as abundant as the protons (Hillas. pp. 67-9). The sky "shines" as brightly with cosmic rays as it does with starlight (Watson). The most energetic cosmic rays have an energy at least 100 billion times the average. Such cosmic rays are very rare.
