Supernova explosions are believed to have played a crucial role in the formation of heavy elements essential for the creation of rocky planets. These colossal explosions occur at the end of a star's life cycle, releasing immense energy and generating the heat necessary for synthesizing heavy elements from lighter ones. This process facilitated the development of elements like iron, nickel, and gold, which are fundamental to the composition of terrestrial planets.

As a result of these cosmic events, the heavy elements spread throughout the universe, contributing to the material that would eventually form rocky planets, including Earth. This intricate lifecycle of stars and the subsequent formation of planets underscore the significance of supernovae in cosmic evolution, linking them to the emergence of life and our existence today.
