When a super-giant star explodes it shines brighter and turns into a supernova.
Iron is the heaviest element formed by fusion in the core of a supergiant star prior to its supernova explosion. Elements heavier than iron are typically formed during the supernova explosion itself through nucleosynthesis processes.
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
