You’re Made of Stardust: The Chemistry Behind Your Cosmic Origins   Did you know that you’re literally made of exploded stars ? It's true! Every atom in your body   carbon, nitrogen, oxygen   was formed in the heart of a star billions of years ago. You’re a living testament to the wonders of the universe’s most powerful events: supernovae. The Birth of Elements in Stars Stars aren’t just shining balls of gas; they’re cosmic factories, where elements are born through nuclear fusion. In the core of stars, atoms of lighter elements like hydrogen and helium fuse to create heavier elements like carbon, oxygen, and nitrogen. This process is the cosmic chemistry that gives rise to everything around us—including ourselves. The Supernova: An Explosive Finale As stars age and run out of fuel, they explode in a massive event known as a supernova . These explosions are so intense that they create even heavier elements, like gold, uranium, and iron, which are scattered across space. W...
