This pale blue dot, is our Earth.

"If you study this picture taken in 1990 from a distance of 6 billion kilometres  from deep space by the Voyager 1 spacecraft, you see a dot.  That's Earth. That's home. That's us. "

"On it, everyone you ever heard of, every human being who ever existed, lived out their lives here. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilisations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every 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 rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. 

Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. 

How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturing, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light."

"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."
