Detailed explanation-1: -During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Detailed explanation-2: -This shock wave compresses the material it passes through and is the only place where many elements such as zinc, silver, tin, gold, mercury, lead and uranium are produced.

Detailed explanation-3: -The only way to create substances heavier than iron is by a process called neutron capture, where neutrons penetrate an atomic nucleus-for example, an iron atom-which absorbs the neutrons, creating a new, heavier atomic nucleus and thus a new element.

Detailed explanation-4: -These fusion reactions create new atomic nuclei in a process called nucleosynthesis. Supernovae are considered one of the original sources of the elements heavier than iron in the Universe. Even the iron in your blood can be traced back to supernovae or similar cosmic explosions from long before our Sun had formed.

Detailed explanation-5: -The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions.
