Home a Pale blue dot. Another Pocket Story.

After travelling 6 billion kilometers, Nasa space probe Voyager 1, turn back its cameras and took a photo of Earth. Today we revisited the pale blue dot that we call Home.

“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."
Carl Sagan.

This is the "Pale Blue Dot" photograph of the Earth taken by the Voyager 1 spacecraft on July 6, 1990. The Earth is the relatively bright speck of light about halfway across the uppermost sunbeam. The original version of this image can be obtained from NASA. The original caption reads as follows: This narrow-angle color image of the Earth, dubbed 'Pale Blue Dot', is a part of the first ever 'portrait' of the solar system taken by Voyager 1. The spacecraft acquired a total of 60 frames for a mosaic of the solar system from a distance of more than 4 billion miles from Earth and about 32 degrees above the ecliptic. From Voyager's great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera. Earth was a crescent only 0.12 pixel in size. Coincidentally, Earth lies right in the center of one of the scattered light rays resulting from taking the image so close to the sun. This blown-up image of the Earth was taken through three color filters -- violet, blue and green -- and recombined to produce the color image. The background features in the image are artifacts resulting from the magnification.





En esta excepcional imagen tomada el 19 de Julio de 2013, la cámara gran angular de la sonda Cassini de la Nasa ha fotografiado en la misma imagen los Anillos de Saturno junto con el planeta Tierra y la Luna.
