The US military has been very worried about the effect of cosmic rays on the eye since the early 1970s, but they have never been able to prove conclusively that this is the case. If there were lots of cosmic rays to see, the atmosphere would be clogged with it and it would be impossible to observe them because they would hit the eye and burn the retina. But this is only because there are so few of them. In fact, there are only a handful of places on Earth that can see them. Here on Earth, cosmic rays are very hard to see because they are so high energy. Because they are so powerful, we can only find them by observing the sky. They travel at such high speeds that they can reach Earth’s surface in just a few hours. And galactic cosmic rays are one of the most powerful sources of radiation to be found on the Earth’s surface. These particles are so powerful that they can knock electrons out of atoms, causing them to become unstable.Ĭosmic rays are also called galactic cosmic rays (GCR) because they are coming from space. For example, if you live near a certain star, then you are very likely to be subjected to high energy cosmic rays. So if you are a person who spends a lot of time in space, then you are likely to be exposed to large amounts of cosmic rays. This bombardment of high energy particles is what causes the atmosphere to be so charged. The high energy particles are very short-lived because the large objects are pushed away from the Earth very quickly. This bombardment causes those powerful objects to be pushed away from Earth. They are a type of particle that is produced in the atmosphere during the bombardment of the Earth by powerful space objects. These particles are made up of protons and electrons.Ĭosmic rays are also known as high energy particles. The third type of cosmic ray is the charged particles. These are the particles that make up your atmosphere and the Earths magnetosphere. The second type of cosmic ray is the neutral particles. These particles are about ten times more powerful than a normal gamma ray. These are the particles that are produced in the most powerful star colliders. These are the particles that cause the most damage to your eyeball. The galactic cosmic rays that hit your eyeball are extremely high-energy particles (gamma rays), and they usually originate from a star that’s relatively close to Earth. They are also the source of the most intense gamma rays ever detected, and these are what cause the most damage to your eyeballs. Today’s news at 9.30 am: galactic cosmic rays, as the name suggests, are all about cosmic rays.Ĭosmic rays are an important component of the atmosphere and the Earth’s magnetosphere.
