Heat from nuclear fusion produces massive amounts of energy. Thermal energy is usually associated with Light. The concept of heat creating light is the same basis as to why light bulbs get hot when you turn them on, or why metal gets bright red when you heat it up.

Since light is around us everywhere we should understand how it is created. Simply put, all forms of Electromagnetic (E.M.) radiation are created when a valence electron drops from a higher energy state to a lower one. The loss of energy which occurs is emitted in the form of radiation with an energy which exactly matches. This is called a photon.
