Carl Sagan famously reveled in the fact that “we are stardust,” because the elements that compose us are derived from the birth of stars and the explosion of supernovae [emphasis added]. These events are only the beginning of our deep connections to the universe. Written inside of us is the birth of the solar system and workings of the planet itself.
