Pale Blue Dot: the photograph that changed humanity's perspective

1990

On February 14, 1990, the Voyager 1 spacecraft, 6.06 billion kilometers from Earth (beyond Neptune's orbit) rotated its camera and took one last photograph of our planet.

In the image, Earth appears as a tiny dot, less than a pixel, suspended in a scattered beam of sunlight. The photograph was taken at the request of astronomer Carl Sagan, who had persuaded NASA to program this final portrait before Voyager's cameras were shut down permanently.

Sagan looked at the photograph and wrote a text that entered history:

"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives."

"The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species lived there, on a mote of dust suspended in a sunbeam."

The photograph and Sagan's text became a symbol of our place in the universe. In an era of conflicts, borders, and national egos, a single image showed that all our disputes take place on a nearly invisible point in the vastness of the cosmos.

Voyager 1 continues to fly. In 2012, it entered interstellar space, the first human-made object to leave the heliosphere. In 2025, it's over 24 billion kilometers from Earth. Its radio signals, traveling at the speed of light, take over 22 hours to reach us.

Aboard Voyager is the Golden Record: a phonograph disc with sounds and images from Earth, intended for any extraterrestrial civilization that might find the probe. It includes music by Bach, greetings in 55 languages, and the sound of ocean waves. It is a bottle tossed into an infinite cosmic ocean.
