Nuclear fusion in the heart of the sun.

The energy of the Sun
The main source of energy for our planet and the entire solar system is none other than the sun itself. Our star, 1.4 million kilometers in diameter (110 times the Earth) sends us in the form of heat 8000 times more energy than that consumed by the world population from all sources. If we do not know how to exploit it enough, we know how it is created. Everything starts from the heart of the Sun, which is so hot that it triggers the nuclear fusion of its atoms (usually hydrogen), usually a phenomenal amount of heat that reaches us, 150 million kilometers away.
Nuclear fusion in the heart of the Sun
1. Deuterium and tritium are isotopes of hydrogen (the main element of the sun): 2 atoms that have the same number of protons, but no neutrons.
2. Heat causes nuclear fusion: the hydrogen atoms fuse.
3. Nuclear fusion creates a new helium atom, lighter than the sum of the fused atoms.
4. The remaining mass is evacuated as energy (heat), according to the famous formula of Albert Einstein: E = mc 2 squared: the energy (E) is equal to the mass (m) multiplied by the square of the speed of light (c squared).
Nuclear nucleus at 15 million degrees Celsius
It is in the nucleus 500,000 km in diameter that the extreme temperature triggers nuclear fusion reactions, which then maintain this temperature.
Then the temperature cools down to less than 6000 degrees Celsius on the surface of the Soeil.
Solar corona at 1,000,000 degrees Celsius:
Much hotter than the surface, because of a layer of plasma below the surface of the Sun, which acts like a boiling pan.
Structure of the Sun:
1. chromosphere.
2. Convection zone (Photosphère).
3. Radiation zone.
4. Nuclear nucleus.
