Cosmic rays Gamma Rays Astronomy.
The earth is bombarding by elementary particles and atomic nuclei of very high energies. They are Oriented from outer space, such as the sun, neutron stars, black holes, and etc. These particles may produce secondary particles that penetrate Earth's atmosphere. The number of particles start to increase rapidly as this shower or cascade of particles mores downwards in the atmosphere. We call this an Extensive air shower. Extensive air showers can be detected with different kinds of particle detectors. We carry out the detection by scintillation detectors. So, we can find direction and energy of primary particles and finally their sources.
