Discovery Of Cosmic Rays, The Nature And Origin Of Cosmic Rays
The term cosmic ray refers to tiny particles of matter that travel through space. Cosmic rays generally possess an electromagnetic charge and are highly energetic. Physicists divide cosmic rays into two categories: primary and secondary. Primary cosmic rays originate far outside Earth's atmosphere. Secondary cosmic rays are particles produced within Earth's atmosphere as a result of collisions between primary cosmic rays and molecules in the atmosphere.
