During which violent event are elements heavier than iron, such as gold and uranium, typically synthesized?
Answer
Supernovae
Elements significantly heavier than iron require extremely high energy events, typically achieved during the explosive death of massive stars known as supernovae, via the rapid neutron capture process.
