This excerpt from Carl Sagan’s book Pale Blue Dot (1994) was inspired by an image taken at Sagan’s suggestion, by Voyager 1 on Feb14, 1990.

From a distance of about 6 billion km, Voyager 1, which had completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its camera around and take one last photo of Earth across a great expanse of space, at the request of Carl Sagan. 

The accompanying words, written 25 yrs ago are still relevant today.
