These blasts scatter heavy elements such as carbon and iron into space, helping enrich the universe. A different and far rarer kind of cosmic explosion, known as a kilonova, happens when two neutron stars collide. Neutron stars are the dense remnants of dead stars, and when they merge, they can create even heavier elements, including gold and uranium. Materials like these later become part of new stars, planets, and other cosmic structures."
