Professor Brian Cox demonstrates how the chemical elements are made in the death throes of a dying star. All 92 elements on Earth, including those that make up our bodies, were formed at the heart of a star. Small stars like our Sun produce the lighter atoms through fusion reactions. Larger stars with heavier cores make the heavier elements up to iron. The rest are forged by exploding supernovae or the death of largest stars.
