When a massive star exhausts its nuclear fuel and develops an iron core, the core collapses catastrophically in a fraction of a second, triggering a supernova explosion that can outshine entire galaxies; the remnant becomes either a neutron star (if the core mass is moderate) or a black hole (if the core mass is extremely high), with the latter being a region where gravity is so intense that nothing, not even light, can escape.
