The vast distances that separate the stars are providential. Beings and worlds are quarantined from one another. The quarantine is lifted only for those with sufficient self-knowledge and judgment to have safely traveled from star to star.

In all our searching, the only thing we've found that makes the emptiness bearable is each other.

The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground.

Across the sea of space, the stars are other suns.

Sailors on a becalmed sea, we sense the stirring of a breeze.

Billions of years from now our sun, then a distended red giant star, will have reduced Earth to a charred cinder. But the Voyager record will still be largely intact, in some other remote region of the Milky Way galaxy, preserving a murmur of an ancient civilization that once flourished — perhaps before moving on to greater deeds and other worlds — on the distant planet Earth.

Once upon a time, we soared into the Solar System. For a few years. Then we hurried back. Why? What happened? What was 'Apollo' really about?

Otkako su ljudska bića zaposjela Zemlju, noćno je nebo bilo sudrug i nadahnuće. Zvijezde su smirivale čovjeka.Nekima je nebo otvaralo put prema vjeri. Drugima je svemir pružao poticaj za najneobičnija maštanja.

National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of he stars.
