For the 30th anniversary of one of the most iconic views from the Voyager mission, NASA has reprocessed and published a new version of the image known as the “Pale Blue Dot.” It still shows Earth as that single, bright blue pixel in the vastness of space. And that pixel is still caught within a ray of sunlight.
This excerpt from Sagan’s book Pale Blue Dot was inspired by an image taken, at Sagan’s suggestion, by Voyager 1 on Feb.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 km away, when it captured this portrait of our world. Caught in the center of scattered light rays, Earth appears as a tiny point of light, a crescent only 0.12 pixel in size.
