O Pálido Ponto Azul (em 14.02.1990)

Sexta-feira, 14.02.20

Pálido Ponto Azul é uma fotografia da Terra tirada em 14 de fevereiro de 1990 pela sonda Voyager 1, de uma distância de seis biliões de quilômetros da Terra, como parte de uma série de imagens do Sistema Solar denominada Retrato de Família.” (


A Pale Blue Dot



[This excerpt from Sagan's book PALE BLUE DOT was inspired by an image taken, at SAGAN's suggestion, by VOYAGER 1 on FEBRUARY 14, 1990. As the spacecraft left our planetary neighborhood for the fringes of the solar system, engineers turned it around for one last look at its home planet. Voyager 1 was about 6.4 billion kilometers away, and approximately 32 degrees above the ecliptic plane, when it captured this portrait of our world. Caught in the center of scattered light rays (a result of taking the picture so close to the Sun), EARTH appears as a tiny point of light, a crescent only 0.12 pixel in size.]

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 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. 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.


Our posturings, 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.



Carl Sagan


The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.


It has been said that astronomy is a humbling and character-building experience. 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 with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

Pale Blue Dot (Pálido Ponto Azul) representando o nosso planeta tal como registado há 30 anos pela missão Voyager 1 (ainda hoje em movimento e fazendo-o já fora do Sistema Solar logo, de viagem interplanetária passando a interestelar), quando a mesma se encontrava a mais de 40 UA da Terra (a mais de 6 biliões de Km de distância) e feita a pedido do cientista, físico, biólogo, astrônomo, astrofísico, cosmólogo, escritor, divulgador científico e ativista norte-americano ( − Carl Sagan.


E daí saindo o livro de 1994 do escritor nova-iorquino (1934/1996 − morrendo novo de uma pneumonia, uma grande perda para a Humanidade) Pálido Ponto Azul − dando-nos uma nova perspetiva do Sistema Solar (o “Retrato de Família”) e pelo meio, mostrando-nos ao mesmo tempo a aparente pequenez do nosso Mundo, no entanto pendurado na sua grandeza, pois nela contendo (único caso para já conhecido) Vida.
