The Alchemy of Neutron Star Collisions
Season 5
Episode 23
Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. Many heavy elements - includes most precious metals - were produced in an even more spectacular event: the collision of neutron stars.
