The Pale Blue Dot is a photograph of planet Earth taken in 1990 by the Voyager 1 space probe from a record distance of about 6 billion kilometers (3.7 billion miles, 40 AU) from Earth, as part of the solar system Family Portrait series of images. In the photograph, Earth is shown as a fraction of a pixel (0.12 pixel in size) against the vastness of space.

The Voyager 1 spacecraft, which had completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its camera around and to take a photograph of Earth across a great expanse of space, at the request of Carl Sagan. Here is a video with carl sagan voice over that might just change your perception towards fellow living creatures and our home EARTH.
