"Pale blue dot" while leaving our solar system voyager took this picture of earth in a ray of sunlight.

Carl Sagan's take on this picture:

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every 'superstar', every 'supreme leader', every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

It really puts everything into perspective...

I can see my house.

I remember watching Voyager - the farthest on PBS. Apparently NASA had no plans to take the above picture until Sagan lobbied for it.

Everything we've ever known for the entire history of mankind is confined within the parameters of that tiny little blue speck.

"And of all the insignificant human beings on that dot, thatguyx2 was the least significant" - You mean like that?

And at the opposite side of the camera lens

I love the story they told about him selling the missions themselves, he went into the Oval Office and said to the President of the United States, the last time humanity had this chance Thomas Jefferson was sitting at your desk, Mr. President, and he really screwed it up. Nixon laughed good and hard and said "okay, then, let's do two."

Are you sitting in it?

It really puts everything into perspective...

I have a poster of this in my room, I look at it every morning, and I think this final bit is my favorite:

"Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known."
