Look at your wrist, see the blueish veins? The blood flowing through them contains hemoglobin, a protein that has four iron atoms incorporated into its structure. Iron is only naturally produced in one place, it can only be forged in the core of dying stars.
Every time you look at your veins, remember that you are built from, and kept alive by, pieces of stardust.
This is beautiful. I needed this
just learned this in astronomy and can confirm. I love.
….you know iron is mined out of the ground, right?
While it might be mined out of the ground, it’s still only CREATED in stars. just about every element that’s ever been made not by humans can be found through either star fusion or star deaths. So when a star around the size of our sun dies, it spews iron throughout it’s area, some of which accretes into a planet, like Earth.
