The Pale Blue Dot is an iconic photograph of Earth taken by NASA's Voyager 1 Spacecraft on February 14, 1990.   

When Voyager 1 was 3.7 billion miles (6 billion kilometers) miles from the sun, far beyond Neptune,  mission managers commanded it to look back toward home for a final time. It snapped a series of 60 images to create the first "family portrait" of our solar system.

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