Voyager 1's Pale Blue Dot

On February 14, 1990, NASA commanded Voyager 1 to turn its camera around from 6 billion kilometers away and photograph Earth. The result: a single pixel — a pale blue dot suspended in a sunbeam. Carl Sagan's narration of the image remains the most profound 3 minutes of science communication ever recorded. Voyager 1 is now over 24 billion kilometers from Earth, still transmitting data on its 23-watt radio — less power than a refrigerator light bulb — making it humanity's most distant creation.
