The Glowing universe in the eyes of Gama ray: The fate of the cosmic ray factory

July 2, 1986, A very powerful gamma-ray from a distant universe was suddenly caught on an American satellite monitoring the Soviets. -An unimaginably powerful cosmic ray or cosmic ray factory, which hid pulsars, supernova debris, as well as other extragalactic sources, began to find its trace. With this coincidental discovery was born a new eye to see our universe - gamma-ray astronomy! Could this powerful gamma-ray cause our cancer?

 Gamma-ray astronomy is an unprecedentedly beautiful and fascinating field of study in astronomy.  Numerous potent charged particles are constantly raining down on our heads.  We call this charged particle cosmic ray or cosmic ray.  About 90% of cosmic rays are protons, 9% helium, and the rest are high-mass atoms.  The kinetic energy of cosmic rays is huge.  So much so that no laboratory or factory in our world can give so much kinetic energy to any atom.  But in the factory of nature, this powerful cosmic ray is constantly being produced.

 Now naturally, the question comes to our mind that how can the factory of nature create such powerful particles?  Gamma-ray astronomy helps us solve this puzzle of the universe.  Gamma-ray astronomy is relatively new compared to other branches of astronomy.  In the last 10 years, gamma-rays have entered the golden age of astronomy.  Today we will learn about this new astronomy.

 The measure of strength

First of all, we use the electron volt (eV) as a unit of energy in many physics departments (1 eV = 1.6 x 10–12 erg).  The kinetic energy of this cosmic ray or cosmic ray can be up to 1020 eV.  The magnitude of a tennis ball that travels at a speed of 90 kilometers per hour is equal to the speed of a tennis ball.  However, the energy stored in this tennis ball is divided into 1024 atomic particles.  Thus, the amount of energy contained in a particle of a tennis ball is less than 1 electron volt.

 On the other hand, in the case of cosmic rays, this amount of energy, that is, 1020 eV energy, is stored in just one particle!  Through this analysis, we can understand what an infinite amount of energy this cosmic ray can contain.  To date, we have made a maximum of about 13 TeV of proton particles in the accelerator “Large Hadron Collider (LHC)” that we have built in the CERN laboratory on the border of France and Switzerland for 20 years.  (Teraelectron volts; 1 TeV = 1012 eV = 109 keV (kilo electron volts) = 108 MeV (mega electron volts) = 103 GeV (Giga electron volts).) The energy of the cosmos is about a million times greater.  A diagram of energy with light spectra, wavelengths, and their sources is given in Figure 1 to form an idea of ​​different types of energy.
