The sun is a large ball filled with hot air. In the Sun core region, this source of hot air is converted into energy. The energy then moves and spreads through the inner layers to the Sun's atmosphere, then continues to spread energy into the solar system in the form of heat and light.

In the hot air layer, hydrogen element accounts for 72%. Nuclear fusion converts hydrogen into many other chemical elements. In addition, the Sun also contains about 26% of helium elements together with elements such as oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.

All of these chemical elements are formed in the Sun's core and account for 25% of the Sun's total weight. Meanwhile, gravity creates a great pressure and extremely high temperature in the Sun core area with a temperature of up to 15 million degrees Celsius. Hydrogen atoms are repressed and burnt, creating helium and Abundant energy source. The whole process is called nuclear fusion.

The energy source now mainly exists as photons, gamma ray neutrions and is transferred to the radiation zone. These photons may exist in the radiation zone about 1 million years before passing through the divider, or tachocline , between the radiation and convection regions. According to scientists, the Sun's magnetic field is made up of a magnetic dyamo in the tachocline layer.

This metabolic activity makes the surface temperature - the bottom of the Sun atmosphere, also known as photosynthesis, increase rapidly.
