Somos polvo de estrellas

The video explains that humans are made of star ashes, meaning the elements in our bodies originated from stars. After the Big Bang, the universe was too hot for electrons to orbit, forming only hydrogen and helium nuclei. As the universe cooled, stars formed, where gravity allowed for the creation of heavier elements. However, elements heavier than iron form during supernova explosions, which scatter these elements across galaxies, eventually leading to the formation of planets and life.

Describe what happens during a supernova explosion.

How do the remnants of stars contribute to the formation of new planets?
