You Are Made of Star Stuff – Literally!

Every atom in your body was forged in the heart of a dying star. The air, water, and even your DNA are built from elements created in the fiery cores of ancient stars. The Big Bang only produced hydrogen, helium, and a trace of lithium—everything else came from stellar alchemy.

Massive stars fused lighter elements into carbon, oxygen, and nitrogen—essential for life. When these stars exploded as supernovae, they scattered these elements across the cosmos, seeding future planets and life. Even gold and uranium were born in these violent stellar deaths.

Your body is 99% oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus—all stellar remnants. The rest? Traces of sulfur, sodium, and magnesium, each with a cosmic origin. Organic molecules, the building blocks of life, have been found in space, suggesting life’s ingredients existed before Earth.

So when you gaze at the stars, you’re seeing your own creation story. We are the universe, conscious of itself.
