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.
NASA says that, "... cosmic rays go up when solar activity goes down." [1]
Effects on the earth's weather
- Cosmic rays vary the earth’s temperatures by creating more or fewer of the low, wet clouds that cool the earth.
- Cosmic rays amplify small changes in the sun’s irradiance fourfold, creating 1-2 degree C cycles in earth’s temperatures. [2]
