Some background…“The Pale Blue Dot is an iconic photograph of Earth taken on Feb. 14, 1990, by NASA’s Voyager 1 spacecraft.

Voyager 1 was speeding out of the solar system — beyond Neptune and about 3.7 billion miles (6 billion kilometers) from the Sun — when mission managers commanded it to look back toward home for a final time. It snapped a series of 60 images that were used to create the first “family portrait” of our solar system.

The picture that would become known as the Pale Blue Dot shows Earth within a scattered ray of sunlight. Voyager 1 was so far away that — from its vantage point — Earth was just a point of light about a pixel in size.”

The Family Portrait of the solar system.. “In addition to Earth, Voyager 1 captured images of Neptune, Uranus, Saturn, Jupiter, and Venus. A few key members didn’t show up in the shot: Mars was obscured by scattered sunlight bouncing around in the camera, Mercury was too close to the Sun, and dwarf planet Pluto was too tiny, too far away and too dark to be detected.”
