Where did the atoms in my body come from?

About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. The hydrogen atoms in you were produced in the big bang, and the carbon, nitrogen and oxygen atoms were made in burning stars. The very heavy elements in you were made in exploding stars.

What elements in our bodies come from stars?

Hydrogen is formed into helium, and helium is built into carbon, nitrogen and oxygen, iron and sulfur—everything we’re made of. When stars get to the end of their lives, they swell up and fall together again, throwing off their outer layers.

Are we really made of stars?

Most of the elements of our bodies were formed in stars over the course of billions of years and multiple star lifetimes. However, it’s also possible that some of our hydrogen (which makes up roughly 9.5\% of our bodies) and lithium, which our body contains in very tiny trace amounts, originated from the Big Bang.

Do humans have star dust?

Planetary scientist and stardust expert Dr Ashley King explains. ‘It is totally 100\% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. ‘

Did you know that every atom in your body was created by stars?

—Carl Sagan, Cosmos Here’s an amazing fact for your next cocktail party: Every single atom in your body—the calcium in your bones, the carbon in your genes, the iron in your blood, the gold in your filling—was created in a star billions of years ago. All except atoms of hydrogen and one or two of the next lightest elements.

Does every atom in your body come from the Earth?

Every atom in your body (with the possible exception of a few hydrogen atoms) came from the earth. Every atom in your body (with the possible exception of a few hydrogen atoms) came from a star. Can both be true?

Is your body made of Star Stuff?

“Our planet, our society, and we ourselves are built of star stuff.” —Carl Sagan, Cosmos Here’s an amazing fact for your next cocktail party: Every single atom in your body—the calcium in your bones, the carbon in your genes, the iron in your blood, the gold in your filling—was created in a star billions of years ago.

Was Your Body part of a star at one point?

That didn’t have to have been part of a star at any point, since the Big Bang created copious amounts of it. However, because our solar system formed in the vicinity of stellar flotsam, it seems likely that most of the hydrogen in your body would have been part of a star at one point, regardless.
