Energy generated by the sun

NASA/Marshall Solar Physics

Energy is generated in the core, the innermost 25%. This energy diffuses outward by radiation (mostly gamma-rays and x-rays) through the radiative zone and by convective fluid flows (boiling motion) through the convection zone, the outermost 30%. It is now believed that the Sun''s magnetic field is generated by a magnetic dynamo in this

Nuclear fusion in the Sun

The energy from the Sun - both heat and light energy - originates from a nuclear fusion process that is occurring inside the core of the Sun.The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together
