The Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by NASA's Voyager 1 space probe from an unprecedented distance of approximately 3.7 billion miles from Earth. In the image, the Earth is a mere point of light, a crescent only 0.12 pixel in size, and appears as a tiny, pale blue dot. The Pale Blue Dot picture was taken by a camera that shielded and blocked out all but the Earth.

In his 1994 book, Pale Blue Dot, Carl Sagan comments on what he sees as the greater significance of the photograph (video).

It’s pretty humbling to consider the vastness in which we reside. Particularly at a time when life is all-consuming and concentrated on the now. How easy it is to focus on the turmoil perpetuated on our planet, yet it also carries an abundance of positivity and love that we shouldn’t overlook. All compacted into this tiny fraction of a pixel that is currently our everything.
