“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” Carl Sagan Elements emerge from the fusion of collapsing stars, merging stars, "burping" stars, exploding stars, and the Big Bang. This periodic table shows those, color-coding by the origin of the elements in the Solar System. Our Sun isn't massive enough to supernova, but instead will eventually (billions of years from now) expand to a red giant and shrink to a white dwarf. The animation shows the supernova explosion from a star collapse, the origin of many heavier elements, from Kot Da Vinchi, 2011, available on Wikimedia as file Сверхновая_-_supernova.gif Supernovas can't produce enough of the heavier elements like gold, but neutron star mergers have the right conditions to make gold. Note: this periodic table is more recent and accurate than the wikipedia version showing elements by type of star event. This info may further improve in the future.
