Where did the elements in our bodies come from?
From hydrogen forged in the Big Bang to carbon, oxygen, iron, and even gold created through stellar processes, the atoms around us have a cosmic history.
At SpaceCon by ANTARES, we bring this story closer through our Real Elements Display — connecting the elements we can see and touch to the stars and events that created them.
Where Your Elements Came From (APOD: 2026 Sep 14)

Explanation: The hydrogen in your body and present in every molecule of water came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. 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 stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity's best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.
