I believe they are mainly used for observational purposes - that is, they are observed, and conclusions are taken about the Universe.
Gamma rays are a form of electromagnetic radiation, and they are the highest frequency form of that type of energy. They can be said to vibrate fastest. But cosmic rays are mostly protons, which are a form of particulate radiation. Comparing gamma rays to cosmic rays as regards frequency is not something we do.
Cosmic rays can enter Earth through Mars because Mars has a thinner atmosphere than Earth, allowing cosmic rays to penetrate more easily. The lack of a strong magnetic field on Mars also means there is less protection against cosmic rays compared to Earth. This makes Mars a potential gateway for cosmic rays to reach Earth.
Cosmic rays are harmful to living organisms because they are high-energy particles that can damage cells and DNA, increasing the risk of cancer and other health problems. They can penetrate through the atmosphere and into our bodies, causing ionization and mutations in cells. Prolonged exposure to cosmic rays can have detrimental effects on living organisms.
Cosmic rays are continuously present in space - regardless of what day (or year) it is. Luckily, we are protected from cosmic rays on the surface of the Earth by the Earth's atmosphere and magnetic field. A small amount of comic rays can still reach the Earth's surface - particularly at higher altitudes.
Cosmic rays are not part of the electromagnetic spectrum. They are high-energy particles, such as protons and atomic nuclei, that travel through space at nearly the speed of light. Unlike electromagnetic waves, which are composed of oscillating electric and magnetic fields, cosmic rays are actual particles with mass.
There's a considerable (overlapping) range of frequencies for both gamma rays and cosmic rays, but the upper reach for gamma rays is considered to be higher than that for cosmic rays, all the way to 10^30Hz.
Cosmic rays were discovered by Victor Hess in 1912.
the answer is gamma rays
Any energetic event can produce cosmic rays, ranging from supernovae events to quasar jets.

The GZK cutoff is significant in the study of cosmic rays because it sets a limit on the energy levels of cosmic rays that can travel long distances in space without losing energy. This cutoff helps scientists understand the origins and properties of cosmic rays and provides insights into the nature of the universe.
Secondary cosmic rays are the product of collisions with primary cosmic rays. Primary ones are the kind that arrive from space and hit earth - typically air molecules in the upper atmosphere, which creates (and transfers its energy to) other particles, often creating a shower ('air shower') of secondary particles, also of high energy. Even though these products are results of collisions from within the Earth's atmosphere, they are still referred to as cosmic rays, although given the name "Secondary" cosmic rays. Note that secondary cosmic rays' composition or relative composition can differ from the cosmic rays arriving from space; particularly as new particles like muons and pions can be generated.

yes
Technically, "cosmic rays" are high-energy particles rather than electromagnetic radiation. So no, they are not a type of light.
