SOLAR SYSTEM

Detailed explanation-1: -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. Supernovae are thus essential to life.

Detailed explanation-2: -Elements heavier than iron are only produced during supernovae; in these extreme energetic conditions atoms are bombarded by a very large number of neutrons. Rapid successive neutron capture, followed by beta decay, produces the heavier atoms.

Detailed explanation-3: -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-4: -Heavy elements are produced by nucleosysthesis-the fusion of nuclei deep within the cores of stars. At some point in time, the first stars were formed, and within their cores the fusion process created heavier and heavier elements; the most massive stars produced nuclei as heavy as iron.

Detailed explanation-5: -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.
