During this explosion, the extreme temperatures and pressures allow for rapid neutron capture, or the r-process, to occur. When a supernova occurs, telescopes can detect the characteristic signatures of elements like nickel-56 decaying into cobalt and then iron, or the presence of newly synthesized radioactive isotopes.

The Core Collapse and Explosive Nucleosynthesis When the iron core reaches a critical mass, it collapses under gravity at nearly a quarter the speed of light. This ongoing research into stellar evolution and nucleosynthesis ensures that we understand precisely how the universe became capable of supporting life.
Without this continual enrichment, the universe would consist only of hydrogen and helium. During the majority of its existence, a star fuses hydrogen into helium in its core.
The Cosmic Forge: How Supernova Elements Forge Human Origins
Planets like Earth and the complex molecules within our own bodies are only possible because of the material recycled from countless generations of dead stars. The shock wave sweeps up the surrounding gas, triggering the collapse of other molecular clouds and initiating the next generation of star and planet formation.
