Cosmic Ray

Cosmic rays are energetic particles originating from outer space that is in somebody's space on Earth's atmosphere. In high-energy physics, an ultra-high-energy cosmic ray or extreme-energy cosmic ray is a cosmic ray which appears to have tremendous kinetic energy, far additional than both its take it easy mass and energies typical of supplementary cosmic rays. These particles are momentous because they have energy equivalent to the Greisen-Zatsepin-Kuzmin limit.

In the outer space of protons created cosmic rays. When a proton hits the air in the earth's upper atmosphere it produces many particles. The largest parts of these decay or are absorbed in the atmosphere. One type of particle, called muons, lives long sufficient that some reach the earth's surface.

Most huge cosmic rays are almost certainly accelerating in the blast waves of supernova remnants. This does not mean that the supernova detonation itself gets the particles up to these speeds. The cosmic rays eventually escape the supernova residue, they can only be accelerating up to a certain maximum energy, which depends upon the size of the accelerating region and the magnetic field strength.
