Cosmic rays are high-energy radiation that originates from outside the solar system. These energetic particles, mostly protons and atomic nuclei, constantly bombard the Earth's atmosphere. Cosmic rays can also consist of electrons, positrons, and other subatomic particles with high energy levels.

Cosmic rays are not directly related to astronomical stars but are created by high-energy events such as supernovae, black holes, and active galactic nuclei. Traveling at nearly the speed of light, these particles can have a wide range of energies, from a few million electron volts to several joules.

Effects on the Earth's Atmosphere

When cosmic rays strike the Earth's atmosphere, they interact with gas molecules, creating secondary particles such as muons, pions, and neutrons. These secondary particles can then reach the Earth's surface and have biological effects on living organisms. The Earth's magnetic field plays a crucial role in deflecting and modulating the flux of cosmic rays that reach the surface.

Discovery and Study

The existence of cosmic rays was first discovered in 1912 by physicist Victor Hess during a series of balloon flights. Since then, scientists have been studying these high-energy particles to understand their origin, nature, and effects on the universe. The study of cosmic rays has provided valuable insights into the composition of the universe and the interactions between different celestial bodies.

Researchers use ground-based detectors, high-altitude balloons, and satellite-based instruments to study cosmic rays and their properties. Understanding cosmic rays is essential not only for astrophysics but also for space exploration and the protection of astronauts from high levels of radiation in space.
