Pale Blue dot
Seen from about 6 billion kilometers (3.7 billion miles), Earth appears as a tiny dot (the blueish-white speck approximately halfway down the brown band to the right) within the darkness of deep space.
Sagan pointed out that “all of human history has happened on that tiny pixel (shown here inside a blue circle), which is our only home” (speech at Cornell University, October 13, 1994.)
