That is not currently known for sure. Check the Wikipedia article on "Ultra-high energy cosmic rays" for different explanations about how they MIGHT be caused.
Background radiation can come from all sorts of sources, some natural, some man-made.Examples include...cosmic rays from spaceradon gas emitted from the earth's crustelectromagnetic radiation from a number of possible sourcesatomic radiation from nuclear substances.For much more information see Related links below this box.
Cosmic Radiation
Cosmic (Not cosmo) rays do not come from planet. It comes from stars and supernovas. As Mars is a planet, so there does not stand any kind of questions like "Why cosmic rays come from Mars?"
Yes. Its isotropic nature is to one part in ten thousand. This is easy to explain with Big Bang Cosmology, impossible to explain without it. Its minor non-isotropies match exactly what would expect if our Universe began in an inflationary manner.

Electromagnetic radiation that comes from outer space are called, Cosmic Rays.

this is radiation in the microwave part of the electromagnetic spectrum which comes from all directions in outer space
Truer words were never spoken.
Radiation is a natural part of the universe. It comes from cosmic rays, the big bang, stars, rocks, soil, and gasses. Even BANANAS are radioactive. Google "radioactive bananas" for a real treat!
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
microwave radiation is radiation that comes from microwaves
