Final answer:
Elements heavier than Iron (Fe) are synthesized in supernovas, where the conditions allow for nucleosynthesis of these heavy elements, enriching the universe with the chemical diversity we observe.
Step-by-step explanation:
According to scientists, elements heavier than iron are created during the violent events that mark the end of a star's life, particularly in supernovas. In these colossal star explosions, which often occur when massive stars exhaust their nuclear fuel, the necessary conditions for nucleosynthesis occur. This high-energy event allows for the fusion of elements heavier than iron, contributing to the chemical richness of the universe, including the elements found in our solar system and even on Earth itself. Evidence of heavy elements being produced by supernovas can be seen through spectroscopic analysis of ejected materials from such events, as was the case with Supernova 1987A.
