Pierre Teilhard de Chardin Quotes

The objects that are of moderate energy, like our sun or most of the stars that we see in the night sky with the naked eye, are objects in which relatively moderate energy processes are taking place.

Stars that become supernovae start off at least eight times heavier than our sun. They're so short-lived that, even if they have planets, there is unlikely to be time for life to get started. The surface is 40,000C and, as a result, the colouring will be extremely blue.

What goes on inside a star is better understood than one might guess from the difficulty of having to look at a little dot of light through a telescope, because we can calculate what the atoms in the stars should do in most circumstances.

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.

There's truth in light. You can tell what elements a star is composed of and the temperature at which it burns by the light it gives off.

We forget how recently astronomers figured out what the stars are made of, what makes them shine, how distant they are, how they are born, and whether they remain immutable or evolve and die.

We are made of starstuff.

Our present nuclear fusion reactors are classified by the methods used to support the nuclear fusion reaction, which takes place at a temperature much hotter than the surface of the Sun.

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.

We are all made up of stars and all of us are billions of years old - that's what I believe, at least.

The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.

When very large stars die, they create temperatures so high that protons begin to fuse in all sorts of exotic combinations, to form all the elements of the periodic table. If, like me, you're wearing a gold ring, it was forged in a supernova explosion.

Now, our Sun will not collapse to a black hole. It's actually not massive enough.

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?

After all, the universe required ten billion years of evolution before life was even possible; the evolution of the stars and the evolving of new chemical elements in the nuclear furnaces of the stars were indispensable prerequisites for the generation of life.

The whole of the hydrogen on the earth might be transformed at once and the success of the experiment published at large to the universe as a new star.

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.

Even your chin is made up of exploded stars.

Big Bang gave us hydrogen and helium. We couldn't make people out of hydrogen and helium. So we're made out of exploding stars.

Every time four protons are turned into a helium nucleus, two neutrinos are produced. These neutrinos take only two seconds to reach the surface of the Sun and another eight minutes or so to reach the Earth. Thus, neutrinos tell us what happened in the center of the Sun eight minutes ago.

Whether a star has planetary companions or not is a condition of its birth. Those with a larger initial allotment of metals have an advantage over those without.

The sun derives its energy from fusion reactions in which hydrogen is transformed into helium.

We are bits of stellar matter that got cold by accident, bits of a star gone wrong.

All the atoms we are made of are forged from hydrogen in stars that died and exploded before our solar system formed. So if you are romantic, you can say we are literally stardust. If you are less romantic, you can say we're the nuclear waste from fuel that makes stars shine.
