High Mass Stars: Crash Course Astronomy #31

Season 1 Episode 31 | 12m 02s

Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The resulting supernova creates even more heavy elements, scattering them through space.
