Since the discovery of cosmic rays, in 1972, scientists have wondered what produces them, and NGC 3310 has played an important role in resolving this question. The most popular theory has it that cosmic raysΓÇöwhich are really just particles traveling at extremely high velocitiesΓÇöare created in supernova remnants. According to this theory, supernova explosions and the tremendous shock waves that follow them produce cosmic rays.
Using satellites, rockets, and balloons to capture cosmic rays above the EarthΓÇÖs atmosphere, scientists have learned that cosmic rays are produced in galaxies and galaxy clusters. The cosmic rays could be emitted from a black hole in the center of NGC 3310,
