Why does the fusion of nuclei in the central part of stars end with the formation of iron? Is it possible for the formation of elements heavier than iron in stars?

Iron nuclei have the highest specific binding energy. The synthesis of heavier nuclei is no longer accompanied by the release of energy, but requires its expenditure. Such heavy cores are usually formed in supernova explosions.
