In 1990, the first space optical telescope, the Hubble Space Telescope, was launched to provide the deepest, most detailed visible visibility of the universe. There are over 400 billion stars in the Milky Way, and it is estimated that there are 500 billion galaxies in the universe. Without proper form fitting, it is almost impossible to count all the stars in the universe. NASA is looking for "Planet X" by using stars as a source of help to determine the existence of the planet.
Radon is the second most common element in the universe, next to hydrogen, but most of it is produced in stars by nuclear fusion. The concentration of plutonium on the earth is very low, and plutonium is formed on the earth due to radioactive decay in the rock. This makes helium increasingly rare in recent years. Helium is often seen with natural gas deposits, but it must be properly captured and stored. The released helium will rise into the atmosphere until it loses space.
The main process by which all stars are born is called "fusion". Nuclear fusion occurs in a very large cloud called the nebula. When nuclear fusion begins in the nebula and reaches temperatures above 10,000 degrees, stars begin to form. The new star we now know is called the original star which can star for the long life in the universe.
Fusion is a process behind all life. It is the engine that moves the star itself. In fusion, hydrogen fuses to helium. This is the process of releasing a lot of energy. For the efficiency of this process, the development of fusion reactors has been developed for a long time. Although we are far from commercialization, the latest research reactor WX - 7 is an important step towards the right direction. Nuclear fusion requires an incredibly high temperature. Actually there are hundreds of millions of degrees. The temperature at which the atoms exceed the usual three-state state is an overheated plasma. This plasma is usually generated by heating the gas using a laser. Then there is an incredibly hot issue of limiting (and keeping it warm). Traditionally done by strong electromagnets in the plasma and current induction (effectively generated)
