Every atom in your body heavier than hydrogen was forged inside a star
The carbon in your cells, the calcium in your bones, the iron in your blood — all of it was fused in the cores of stars and scattered when they exploded. As Carl Sagan put it: 'The nitrogen in our DNA, the calcium in our teeth, the iron in our blood were made in the interiors of collapsing stars. We are made of star-stuff.'
