Massive-Star Core Collapse

A star born with more than roughly eight solar masses fuses ever-heavier elements until it builds an inert iron core. Iron cannot release energy by fusing, so once the core exceeds its stability limit it collapses in under a second, rebounds, and blows the star apart as a core-collapse supernova, leaving a neutron star or a black hole.
