Gamma rays Marlowe greewell

Gamma rays are waves that are made from radioactive atoms, and nuclear explosions.
The only way we can see gamma rays is with special telescopes in space. We mesure gamma rays in gamma ray photons. The way the telescopes work is with a method of Compton scattering. But unlike some waves, gamma rays cannot be captured or reflected.
The velocity is 186,282 miles per second. The wave length is 10^-11. The frequency is >10^19 hz. Gamma rays have the highest energy of Amy of the electromagnetic waves.
With Gamma rays, we can see things in space that we never could befor. With Gamma rays we can see solar flares, super novas, neutron stars, black holes, active galaxy's. If there were no gamma rays, when we look at the night sky we would not see any stars, but just a lot of purple blobs.
Gamma ray bursts happen are huge bursts of energy. They release more energy in 10 seconds than the sun will ever emit in its whole life. Gamma ray bursts happen every day, but they never happen inside of the Milky Way. A gamma ray burst is the brightest electromagnetic event in the whole universe. They can last from 10 milliseconds to several hours.
Gamma rays are used for lots of medical practices. They are used for treating cancer. They can target a sertin area were the cancer is, and shoot gamma rays into it, which then kills the cancer cells, and makes them not be able to reproduce. They are also used for trasers. Doctors put small amounts of them into a person and they can track it going through a body.
