Quizplus · Accepted Answer

Heavy elements are mostly made in stars through nuclear fusion, but when the star runs out of fuel, it explodes in a supernova, which releases heavy elements into space. Therefore, most heavy elements are made in stars and supernovae. Although some lighter elements were formed in the Big Bang, heavy elements are not believed to have been produced in significant amounts during that event. The interstellar medium may contain heavy elements, but they were not created there.
