On Stars...and On Us

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff - Carl Sagan, Cosmos

While the saying “we are stardust” seems poetic but vague, it is literally true. The atoms of our bodies were created in the cores of stars billions of years ago.
