Nuclear fusion.
The sun is a star, and it is also a nuclear fusion reactor. It is fusing hydrogen into helium to create energy via what we call the proton-proton nuclear reaction. Our local star has been doing this for billions of years, and will continue to do so for billions more.
In a star, nuclear fusion reactions occur. These reactions involve the conversion of hydrogen into helium, releasing immense amounts of energy in the process. This energy is what powers the star and allows it to shine.
The energy in a star is generated by nuclear fusion.
A star gets its energy from nuclear fusion in its core. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy sustains the star and allows it to shine brightly.
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.

A nuclear reaction - either fusion or fission - is required to turn matter into energy.
The energy in a star is generated by nuclear fusion.
Stars create light by fusing hydrogen into helium. This nuclear reaction creates a great amount of energy which releases light and energy. This expanding force a\is counterbalanced by gravity, keeping the star stable.

Nuclear fusion reactions occur in the core of stars, including the Sun, where high pressure and temperature conditions allow hydrogen atoms to combine and release a tremendous amount of energy. Scientists are also working on creating controlled nuclear fusion in experimental reactors on Earth as a potential source of sustainable energy.
