The day we stop exploring is the day we commit ourselves to live in a stagnant world, devoid of curiosity, empty of dreams.

Publicly and among themselves biologists rightly celebrate the diversity of life on Earth... At the end of the day, however, their confession is heard by no one: they work with a single scientific sample-life on Earth.

On some issues, I'm a staunch Conservative — like curtailing greenhouse gas emissions so that we can Conserve the environment.

I don't want people to say, 'Something is true because Tyson says it is true.' That's not critical thinking.

In the movie, the stars above the ship bear no correspondence to any constellations in a real sky.

How lazy can you get?
