Star Stuff (Continued)

It's life that is the priceless part of us. So, I prefer another fact. We are composed of elements that are created in the insides of stars and then distributed around the universe in the stellar wind. As Carl Sagan said, “the iron in our blood, the calcium in our teeth, the carbon in our genes, were produced billions of years ago in the interior of a red giant star. We are star stuff.”

And you can see that star stuff in our eyes.
