“EVERY CHEMICAL ELEMENT on Earth tells a story written in the heavens. The nitrogen in our atmosphere and in your body’s proteins blossomed in stars somewhat heavier than the Sun, such as Capella, which cast their outer layers away as planetary nebulae when they died. The oxygen you breathe and the neon gas in storefront lights were cooked up in massive stars like Antares, which later spewed these elements into the Galaxy by exploding as supernovae. And supernova explosions themselves forged most of the iron in your blood and the gold in your ring.”
