Our passion for learning ... is our tool for survival.

Stars are phoenixes, rising from their own ashes.

Those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.

A galaxy is composed of gas and dust and stars - billions upon billions of stars. Every star may be a sun to someone.

Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.

When you make the finding yourself - even if you're the last person on Earth to see the light - you'll never forget it.

The sky calls to us. If we do not destroy ourselves, we will one day venture to the stars.
