The center line of science literacy - which not many people tell you, but I feel this strongly, and I will go to my grave making this point - is how you think.

One of the things that fascinates me most is when people are so charmed by the universe that it becomes part of their artistic output.
-
I'm constantly claimed by atheists. I find this intriguing. In fact, on my Wiki page - I didn't create the Wiki page, others did, and I'm flattered that people cared enough about my life to assemble it - and it said, 'Neil deGrasse is an atheist.'

The supermoon is a 16-inch pizza compared with a 15-inch pizza. It's a slightly bigger moon; I ain't using the adjective 'supermoon.'

If you want to assert a truth, first make sure it's not just an opinion that you desperately want to be true.
-
You have people who believe they are scientifically literate but, in fact, are not. And I don't mind if you're not scientifically literate, but just admit that to yourself, so that you'll know, and perhaps you can take a first step to try to eradicate that.

If you're going to lead a space frontier, it has to be government; it'll never be private enterprise. Because the space frontier is dangerous, and it's expensive, and it has unquantified risks. And under those conditions, you cannot establish a capital-market evaluation of that enterprise. You can't get investors.

Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth. So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.'
-
If you think of feelings you have when you are awed by something - for example, knowing that elements in your body trace to exploded stars - I call that a spiritual reaction, speaking of awe and majesty, where words fail you.
-
The idea that science is just some luxury that you'll get around to if you can afford it is regressive to any future a country might dream for itself.
-
Any astrophysicist does not feel small looking up at the universe; we feel large.
-
Big ideas, big ambitious projects need to be embedded within culture at a level deeper than the political winds. It needs to be deeper than the economic fluctuations that could turn people against an expensive project because they're on an unemployment line and can't feed their families.
-
So the history of discovery, particularly cosmic discovery, but discovery in general, scientific discovery, is one where at any given moment, there's a frontier. And there tends to be an urge for people, especially religious people, to assert that across that boundary, into the unknown, lies the handiwork of God. This shows up a lot.

You don't take a dead cat to the vet. I mean you might, but why?
-
I've known from long ago that the universe was calling me. If you were one of those annoying adults that said, 'Oh, what are you gonna be when you grow up?' I would say, 'Astrophysicist.' And then they'd walk away real quickly.
-
Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.
-
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
-
I'm often asked by parents what advice can I give them to help get kids interested in science? And I have only one bit of advice. Get out of their way. Kids are born curious. Period.
-
We live on this speck called Earth - think about what you might do, today or tomorrow - and make the most of it.
-
All Plutophiles are based in America. If you go to other countries, they have much less of an attachment to either the existence or preservation of Pluto as a planet.
-
I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.
-
For me at age 11, I had a pair of binoculars and looked up to the moon, and the moon wasn't just bigger, it was better. There were mountains and valleys and craters and shadows. And it came alive.
-
It's part of our pop culture to give animals human personalities and talents.
-
If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.
