How does the sun release energy

This reaction known as nuclear fusion converts hydrogen atoms into helium. the by product of nuclear fusion in the suns core is a massive volume of energy that gets released and radiates outward toward the surface of the sun and then into the solar system beyond it. it also gives heat and light which energize many things

The by-product of nuclear fusion in the Sun's core is a massive volume of energy that gets released and radiates outward toward the surface of the sun and then beyond it.
