We are all made of stars. Supernova earrings tell the story of our cosmic origin.
Supernova is an exploding star. Every star has a core full of nuclear fuel burning inside, assembling heat. This is called nucleosynthesis - the making of elements.
A star is in a balance between two opposite forces. First, the heat from inside creates pressure outward. Second, gravity tries to squeeze the star into the smallest, tightest ball possible. When it runs out of fuel, it cools off. This causes the pressure to drop, and gravity wins. The star suddenly collapses, and within 15 seconds, it creates enormous shock waves that cause the outer part of the star to go supernova.
Stars that go supernova are responsible for creating the elements of the periodic table. So it's very likely that a whole bunch of different stars have contributed to the elements we see in our solar system, on our planet, and those found within you.
