Neil deGrasse Tyson Stars Quotations

Science is a cooperative enterprise spanning the generations. It's the passing of a torch from teacher to student to teacher. A community of minds, reaching back to antiquity and forward to the stars.

I didn't even know there were stars to look at to not see. If you don't know that they're there, you don't know that you're missing them.

For your own safety, do not ever tell an astrophysicist, I hope all your stars are twinkling.

In astrophysics, we care about how matter, motion and energy manifest in objects and phenomenon in the universe. Stars are born. They live out their lives. They die. Some of the ones that die explode. Our sun will not be one of those, but it will die. And it'll take Earth with us. So we make sure we have other destinations in mind when that happens. And I've got it on my calendar.

In the movie, the stars above the ship bear no correspondence to any constellations in a real sky. Worse yet, while the heroine bobs... we are treated to her view of this Hollywood sky-one where the stars on the right half of the scene trace the mirror image of the stars in the left half. How lazy can you get?

There are as many atoms in each molecule of your DNA as there are stars in the typical galaxy. This is true for dogs, and bears, and every living thing. We are, each of us, a little universe.

Stars die and reborn […] They get so hot that the nuclei of the atoms fuse together deep within them to make the oxygen we breathe, the carbon in our muscles, the calcium in our bones, the iron in our blood. All was cooked in the fiery hearts of long vanished stars. … The cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.

Trillions of years into the future, when all stars are gone...all parts of the cosmos will cool to the same temperature as the ever-cooling background. At that time, space travel will no longer provide refuge because even Hell will have frozen over. We may then declare that the universe has died-not with a bang, but with a whimper.

Here's the problem, when you're stargazing on a mountain top you are partially oxygen-deprived and you're in command of million dollars worth of hardware. So as much as I would like to sip wine under the stars, it's contraindicated in the instructions on operating telescopes.

We only recently figured out the origin of our own moon. And we have some idea of how the Sun and Earth formed, but that's only because modern telescopes empower us to see other stars and planets freshly hatched within gas clouds across the galaxy. As for the origin of life itself, the transition from inanimate molecules to what any of us would call life remains one of the great frontiers of biology.

I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.

To achieve this density of a neutron star at home, just cram a herd of 50 million elephants into the volume of a thimble.

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

We can trace the elements. They were forged in the centers of high-mass stars that went unstable at the ends of their lives, they exploded, scattered their enriched contents across the galaxy, sprinkled into gas clouds that then collapsed and formed stars and planets and life.

Perhaps these ancient observatories like Stonehenge perennially impress modern people because modern people have no idea how the Sun, Moon, or stars move. We are too busy watching evening television to care what's going on in the sky.

As the plow pushes through a parking lot of light fluffy snow, the snow clumps together in bigger and bigger chunks. Out in space, pressure hitting a gas cloud has a similar effect, except, instead of snowballs, you get stars!

I'm fascinated by the deaths of stars and the havoc they wreak on their environments.

Once you've got the makings of a star, gravity draws leftover gas and dust into a giant swirling disk. The dust continues to stick together, clumping into rocky asteroids, which eventually become orbiting rocky planets. And voila: a solar system!

If there's some kind of rock star status, would I be irresponsible if I didn't somehow use it for a continued greater good? I'm always involved in some way with reaching the public.

The most accessible field in science, from the point of view of language, is astrophysics. What do you call spots on the sun? Sunspots. Regions of space you fall into and you don’t come out of? Black holes. Big red stars? Red giants. So I take my fellow scientists to task. He’ll use his word, and if I understand it, I’ll say, “Oh, does that mean da-da-da-de-da?

Not only do we live among the stars, the stars live within us.

That the north star is the brightest in the night sky. I'd guess about 9 out of 10 people think this. But it does not require a grant from the National Science Foundation to learn the answer. The North Star is not even in the top 40 in the night sky. It's the 49th brightest star. Rather dull and boring by most measures.

We are star dust in the highest exalted way, called by the universe, reaching out to the universe

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.

It makes good sense to revere the sun and the stars ... because we are their children

George Bush, within a week of this [the 9/11 attacks], in a speech, attempting to distinguish US from the Muslim fundamentalists, said Our God is the God who named the stars. The problem is: two-thirds of all stars that have names, have Arabic names. I don't think he knew this. That would confound the point that he was making.

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.

I'm not criticizing the science in Star Wars. That's a waste of everybody's time.

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.

It's quite literally true that we are star dust, in the highest exalted way one can use that phrase. ...I bask in the majesty of the cosmos. I use words, compose sentences that sound like the sentences I hear out of people that had revelation of Jesus, who go on their pilgrimages to Mecca.

The molecules that comprise our body are traceable to the crucibles of the centers of stars.These atoms and molecules are in us because, in fact, the universe is in us. And, we are not only figuratively, but literally, stardust.
