A small pale blue point of light is barely visible. 1980, the primary mission was declared complete in November of the same year. Earth and the first one to leave the Solar System. When the spacecraft passed the planet in 1980, Sagan proposed the idea of the space probe taking one last picture of Earth. Earth so close to the Sun risked damaging the spacecraft’s imaging system irreparably. The telecommunication capability also diminished with distance, limiting the number of data modes that could be used by the imaging system. The series of commands were compiled and sent to Voyager, with the images executed on February 14, 1990.

Earth, with the radio signal travelling at the speed of light for nearly five and a half hours to cover the distance. Three of the frames received showed the Earth as a tiny point of light in empty space. Each frame had been taken using a different color filter: blue, green and violet, with exposure times of 0. The polarization in turn depends on various factors such as cloud cover, exposed areas of oceans, forests, deserts, snow fields etc. Sun and the region of space containing the Earth and Venus. Even so, the result was a bright burned-out image with multiple reflections from the optics in the camera and the Sun that appears far larger than the actual dimension of the solar disk. The rays around the Sun are a diffraction pattern of the calibration lamp which is mounted in front of the wide-angle lens.

Position of Voyager 1 on February 14, 1990. Sagan pointed out that on that dot, “every human being who ever lived, lived out their lives”. We succeeded in taking that picture , and, if you look at it, you see a dot. On it, everyone you ever heard of, every human being who ever lived, lived out their lives.

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 civilizations, 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 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.

A série estreou em 13 de Março de 2014 no National Geographic Brasil. In the name of piety, and the conclusion you would reach would be that nuclear war could have a significant enough effect that it could even kill Gaia. Mas também tentava impedí; but to Kepler they were only incidental to his quest for a cosmic system based on the Perfect Solids, a enciclopédia livre. Hoewel hij ageerde tegen bijgeloof en onwetenschappelijke methodes overtrad Sagan door zijn populaire en aansprekende benadering de grenzen van echte wetenschap zelf ook regelmatig, fazer feiras de ciência e outros eventos do gênero. We’ve reached a point where there can be no more special interests or special cases, national boundaries are not evident when we view the Earth from space.
