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.

We are made of starstuff.

We are made of star-stuff. Our bodies are made of star-stuff. There are pieces of star within us all.

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 star stuff

We're made of star stuff. We are a way for the cosmos to know itself.

93 percent stardust,
with souls made of flames,
we are all just stars
that have people names.

all the atoms that make each of us up — the iron in our blood, the calcium in our bones, the carbon in our brains — were manufactured in red giant stars thousands of light-years away in space and billions of years ago in time. We are, as I like to say, starstuff.

Have you ever considered the fact that everything we are originates from the remnants of stars that once exploded?” Jorrus said, “Vita ex pulvis.” “We are made from the dust of dead stars.

We are star stuff harvesting sunlight.

We are all creatures of the stars.

Our Sun is a second- or third-generation star. 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.

We are all stardust and stories.

In a sense, human flesh is made of stardust. Every atom in the human body, excluding only the primordial hydrogen atoms, was fashioned in stars that formed, grew old and exploded most violently before the Sun and the Earth came into being. The explosions scattered the heavy elements as a fine dust through space. By the time it made the Sun, the primordial gas of the Milky Way was sufficiently enriched with heavier elements for rocky planets like the Earth to form. And from the rocks atoms escaped for eventual incorporation in living things: carbon, nitrogen, oxygen, phosphorus and sulphur for all living tissue; calcium for bones and teeth; sodium and potassium for the workings of nerves and brains; the iron colouring blood red… and so on. No other conclusion of modern research testifies more clearly to mankind’s intimate connections with the universe at large and with the cosmic forces at work among the stars.

We hang here, inquisitive carbon-based life forms, knowing that every atom of carbon now in our bodies was once in the interior of a star.
