The Lives of the Stars is the ninth episode of Cosmos A Personal Voyage. It first aired 23 November 1980 on PBS.


The simple act of making an apple pie is extrapolated into the atoms and subatomic particles necessary. Many of the ingredients necessary are made of chemical elements formed in the lives and deaths of stars, resulting in massive red giants and supernovae or collapsing into white dwarfs, neutron stars, pulsars, or even black holes. These produce all sorts of phenomena, such as radioactivity, cosmic rays, and even the curving of spacetime by gravity.
