Internal structure of the Sun, artwork
Internal structure of the Sun, cutaway artwork. At the Sun's core (white) hydrogen atoms undergo nuclear fusion, producing helium atoms and releasing heat and light energy as photons. These radiate outwards through the inner region (radiative zone) to the outer convection zone layer. Here, solar plasma rises in thermal columns to the visible surface (photosphere). Intense magnetic fields and plasma tornadoes channel the distribution of energy towards the surface of the Sun. Solar prominences and flares erupt from the Sun's surface, with regions of immense turbulence and high temperatures.
