Meet your maker

Meet your maker
We all are children of supernovae


The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions. Even heavier elements are born in the extreme conditions of the explosion itself. 

Without dying stars, life would not be possible. Our blood has iron in the hemoglobin which is vital to our ability to breath. We need oxygen in our atmosphere to breathe. Nitrogen enriches our planet's soil. 
Without supernovae, we can have gas planets, stars and galaxies but not cars, cows, solid planets, humans or any life. We all are children of supernova explosions.
