The origins of the elements
- The hydrogen in our bodies, present in every molecule of water (H2O), came from the Big Bang. There are no other appreciable sources of hydrogen in the universe.
- The carbon in our bodies was made by nuclear fusion in the interior of stars, as was oxygen. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements. Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen, and iron, which were created by stars that existed before them. After a star runs out of fuel, it ejects much of its material back into space going novae or supernovae. The major difference between a nova and a supernova is that in a supernova a lot of the object’s mass is ejected with the explosion (and some of this ejected material creates new stars and planets, like our sun and the solar system planets, and the elements like carbon and oxygen in our bodies come from this ejected material). The amount of this mass is more than the mass of the sun. Whereas in a nova, very less mass is ejected as compared to that in a supernova. A nova also does not destroy its host star whereas a supernova does.
- White dwarf supernova: in this type of supernova, a white dwarf in a binary star system gains mass from its companion. As its mass increases, the temperature and pressure within the white dwarf also increase, until nuclear fusion re-ignites at its center. A white dwarf is so dense that fusion sweeps rapidly out from the center, releasing a tremendous amount of energy that blows the star apart.
- Much of the iron in your body was made during supernovas of stars that occurred long ago and far away.
- The gold in your jewelry was likely made from neutron star mergers that may have been visible as short-duration gamma-ray bursts or gravitational wave events.

Carl Sagan – Cosmos: Stars – We Are Their Children
The surface of the Earth is the shore of the cosmic ocean. On this shore, we’ve learned most of what we know. Recently, we’ve waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We’re made of star stuff. We are a way for the cosmos to know itself.
