S1E2: We Are Made of Exploded Massive Star Dust
You’ve probably heard that **we’re made of stardust**. But what does that actually mean, and which parts of us really came from stars? In this episode of *Cosmic Fossils*, we go inside a massive star and follow its life all the way to the end: from hydrogen and helium burning, through the creation of carbon and heavier elements, to the iron core that ultimately triggers its collapse. We’ll talk about the famous **B²FH paper**, Margaret Burbidge and the origins of stellar nucleosynthesis, the Hoyle resonance, why fusion stops releasing energy at iron, and what happens in the final second before a massive star explodes. And then we come back to us: the **oxygen you breathe, the calcium in your bones, and the iron in your blood**. Where were they actually made? Because “we are made of stardust” is beautiful, but the real story is even more interesting. ✨ *Cosmic Fossils* is a series about stars, their remnants, and what they can tell us about the history of the Universe.
