What is the internal structure of the sun?

The Sun's internal structure consists of several layers, primarily the core, radiative zone, and convective zone. The core, where nuclear fusion occurs, generates energy and is extremely hot and dense. Surrounding the core is the radiative zone, where energy is transferred outward through radiation, and above that is the convective zone, where energy is transported by convection currents. This layered structure plays a crucial role in the Sun's energy production and overall dynamics.
