The sun's energy enough for 5 billion years

For a long time, astrophysicists observe solar activity, and during this period, scientists discovered many interesting facts.

As you know, in the course of its activity, the last layer of the Sun's atmosphere is constantly emits a number of its constituent particles, such as protons, neutrinos, alpha particles and electrons. This stream of particles called "solar wind", the speed is 400 - 500 kilometers per second. Solar wind breaks through the hole in the atmosphere, thus there is a flash of enormous power. The nature of the outbreak is linked to changes in the magnetic field.

What is the energy source of the sun and how long it will warm us with its warmth? Until recently, in this respect, there are several theories that have successively been rejected due to its insolvency. The main theory about the energy of the sun, having a plurality of acknowledgments, is the theory of Hans Bethe, according to which in light of the ever happen thermonuclear reactions that convert hydrogen to helium, with the result that stands out enormous energy, in addition, synthesized and distributed in space so-called solar particles mentioned previously. According to recent research estimates the stock elements of the sun enough for about five billion years, after which its internal processes will undergo significant changes. Sun will begin to expand, absorbing located near the planet of its system, in turn, our planet loses biological life forms, and its inhabitants will be forced to move to other planets, more suitable for living. After the expansion stage the Sun will move into a stage of compression, it will start to cool, and just two billion years after the beginning of the events in question will become a cold cosmic body.
