What’s the human body made of? Ninety-nine percent consists of atoms of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus, with the remaining one percent consisting of trace elements like magnesium, sulfur, and iron. But where did those elements come from?
All heavy elements were created within stars via nuclear fusion — a process known as stellar nucleosynthesis. As stars cool and “die,” they release the heavy elements into space. Ultimately, some of this material is incorporated into planets and even our bodies.
That’s right, the atoms in YOUR body were fused in a dying star and blasted into space in a supernova. You are STAR STUFF.
