supernova
Scientist believe that the universe by a giant explosion called the big bang .
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.
No, the moon is not a giant ball of fire. It is a rocky object that reflects the light of the sun, which is why we see it bright in the sky.

The currently most-accepted theory is that it was the result of an impact, of a giant object with Earth.

Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
As heavier elements are formed by fusion in the core, a massive star will eventually exhaust its nuclear fuel and trigger a supernova explosion. This explosion will generate immense energy, leading to the production and dispersal of even more heavy elements into space.
