Abstract In 1950 Alfven and Herlfson as well as Wepenhens showed that nontherrnal cosmic radiation may be explnined by relativistic electrons moving in interstellar magnetic fields. Since the nonthermal radicemission of the galaxy is caused by relativistic electrons that move in interstellar magnetic fields, it becomes possible to observe the electron component of the primary cosmic rays in the universe. From the analysis of the conditions of discrete sources it was concluded that only relativistic electrons moving in rnagnetic fields can be responsible for their radiation. From the observed flax of radioemission of the Crab Nebula, the quantity of relativistic electrons and their energy were evaluated. These calculations showed that an explosion of a supernova results in the formation of a large number of relativistic particles. It has been shown that taking into account the frequency of out bursts of supernovae in our galaxy and the "duration of life'' of cosmic rays in interstellar media, the quantity of relativistic particles actually formed during these out bursts was quite enough to provide the observed concentration of primary cosmic rays. Thus it was shown that supernovae explosions may be the infectors of primary cosmic rays in our stellar system. (A.C.)
