As Carl Sagan used to say, we are made of “star stuff”. It sounds like a line from a poem, but there is some concrete science behind this statement: almost every element on Earth was formed at the heart of a star. The carbon, nitrogen and oxygen atoms in our bodies, as well as atoms of all other heavy elements, were created in previous generations of stars over 4.5 billion years ago. So next time youre out gazing at stars twinkling in the night sky, remember, we are all made of star dust, we are all one!
