Cosmic rays are particles that bombard the Earth from outer space, such as::
- Galactic Cosmic Rays -- coming from outside the solar system
- Anomalous Cosmic Rays -- coming from the interstellar space at the edge of the heliopause
- Solar Energetic Particles -- associated with solar flares and other energetic solar events
The term "cosmic rays" used to include X-rays and gamma rays.
