What if all of human history fit inside a single pixel?
In 1990, after more than a decade of travelling outwards through the solar system, Voyager 1 turned its camera back towards home. From about 6 billion kilometres away, it took a photograph. Earth is in that photograph. You have to look carefully, because our entire world — every city, every ocean, every person who has ever drawn breath — shows up as a pale blue speck, less than a pixel wide. That one point of light holds every war ever fought, every love story ever lived, every king and every farmer. The image went on to inspire Carl Sagan's most celebrated reflection on human existence. Nothing he said required exaggeration. The photograph did the work. Follow Deep Field Vault for more of the universe, one true fact at a time.
