On February 14, 1990, NASA commanded the Voyager 1 spacecraft, having completed its primary mission, to turn around to photograph the planets it had visited. One image Voyager returned was of Earth, 4 billion miles distant, showing up as a tiny dot. “The spacecraft was a long way from home. I thought it would be a good idea, just after Saturn, to have them take one last glance homeward. From Saturn, the Earth would appear too small for Voyager to make out any detail. Our planet would be just a point of light, a lonely pixel hardly distinguishable from the other points of light Voyager would see: nearby planets, far off suns. But precisely because of the obscurity of our world thus revealed, such a picture might be worth having.” “It had been well understood by the scientists and philosophers of classical antiquity that the Earth was a mere point in a vast, encompassing cosmos — but no one had ever seen it as such. Here was our first chance, and perhaps also our last.” “So, here they are: a mosaic of squares laid down on top of the planets in a background smattering of more distant stars. Because of the reflection of sunlight off the spacecraft, the Earth seems to be sitting in a beam of light, as if there were some special significance to this small world; but it’s just an accident of geometry and optics. There is no sign of humans in this picture: not our reworking of the Earth’s surface; not our machines; not ourselves. From this vantage point, our obsession with Great video bring with hitvideo.org

    good video but the music drowns out his voice.

    It slays me still that more young people know who Speidi is than Carl Sagan. This man demonstrates, even posthumously, his outstanding compassion for all life and his keen ability for clear and sensible reasoning. He was and continues to be a gift to humanity. Perhaps one day, when mankind catches up to where he was, the majority of us will finally be grateful for his existence.

    Every person on Earth should see this.

    @thefutureboom I don’t know, it might make some people suicidal. I’ve seen this what, a dozen times now, and it still kinda gets to me (in the bad way, though it also has the same powerful positive message).

    The most beautiful, and breathtaking words ever spoken.

    you tube should have this video permanently promoted, his speech needs to be put in the school curriculum as mandatory listening/reading, and if anyone tries to start a fight, make them listen to carl sagan pale blue dot on repeat for 1 hour, not that is a punishment to listen to carl sagn, but maybe no more fighting after that

    I’ve seen many videos since this. It is STILL the best video on Youtube, every human being should be well acquainted with the name ‘Carl Sagan’

    …and Mogwai ;-)

    In this passage Carl Sagan shows himself to be one of the finest philosophers of the twentieth century.

    If this is to be the only message left behind by humanity, I’d be content.

    what I mean is that if you hear what the Voyager had recorded until now you will realize about the immensity of the universe. It is juts overwhelming! I know that the satellite does not feel, do not be silly!

    @analfabeta44 : The Earth is lonelier. The Earth can feel, the satellite doesn’t have emotions.

    Me too, yet you’d think it would be the other way around.

    I realy like the irony of the words “…so all those generals and emperors could become a momentary masters of the fraction of the dot”. It is comforting that no mater how “big” some people think they are in reality you are simply inconsequential.

    As of August 28, 2009, Voyager 1 was about 110.94 AU (16.596 billion km, or 10.312 billion miles) from the Sun, and has passed the termination shock, entering the heliosheath, with the current goal of reaching and studying the heliopause, which is the known boundary of the solar system.

    It takes something like 14 hours for messages from earth to reach it. . .

    That’s just incredible.

    Somehow, this is comforting to me…
