Stellar Origin Quotes

All of the rocky and metallic material we stand on, 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 made of star stuff.

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.

We are star stuff which has taken its destiny into its own hands. The loom of time and space works the most astonishing transformations of matter.

We are one species. We are starstuff.

We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star.

The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.

Recognize that the very molecules that make up your body...are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.

You and I are made of stardust. We are the stuff of exploded stars. We are therefore, at least 1 way that the Universe knows itself. That, to me, is astonishing.

Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numberous and so vigorously recycled at death that a significant number of our atoms-up to a billion for each of us, it has been suggested-probably once belonged to Shakespeare. A billion more each came from Buddha and Genghis Khan and Beethoven, and any other historical figure you care to name.

From which stars have we fallen to meet each other here?

I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up — many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars.

The fact is that every atom that we're made of is part of that first explosion of a nuclear star billions of years ago. We're connected to the entire universe.

Here's a question we all ask ourselves at least once when we're young: Where does that starlight come from? It's been there before I was born, and before my grandmother, and her grandmother were born. So just how far is that star from Earth?

Nothing can stop us now 'cause we are all made of stars.

As much as I love my family, I enjoy it when the house is empty, because then I know I'm truly alone, as we all are on the planet, after all. Every atom in us is originally from a star. And during my moments of aloneness, I'm most mindful of that; that I'm just another group of matter randomly but wonderfully arranged. That's when I feel my immortality.

The iron from that meteorite and the iron from your blood have common origin in the core of a star.

We are 'nuclear waste' from the fuel that makes stars shine; indeed, each of us contains atoms whose provenance can be traced back to thousands of different stars spread through our Milky Way.

What is it that you contain? The dead. Time. Light patterns of millennia opening in your gut. Every minute, in each of you, a few million potassium atoms succumb to radioactive decay. The energy that powers these tiny atomic events has been locked inside potassium atoms ever since a star-sized bomb exploded nothing into being. Potassium, like uranium and radium, is a long-lived radioactive nuclear waste of the supernova bang that accounts for you. Your first parent was a star.

We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.

The soul of man is of the imperishable substance of the stars!

I tell my students, with a feeling of pride that I hope they will share, that the carbon, nitrogen, and oxygen that make up ninety-nine per cent of our living substance were cooked in the deep interiors of earlier generations of dying stars. Gathered up from the ends of the universe, over billions of years, eventually they came to form, in part, the substance of our sun, its planets, and ourselves. Three billion years ago, life arose upon the earth. It is the only life in the solar system.

The amazing thing is that every atom in your body came from a star that exploded.

Every atom in your body came from a star that exploded. And the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: you are all stardust.
