Two machines launched in 1977 have traveled farther from Earth than any earlier human-made explorers. Voyager 1 and Voyager 2 transformed our view of the outer planets and then continued outward, carrying a deliberately human artifact: the Golden Record.

A planetary tour that became something larger

The Voyagers returned close-up observations of giant planets, moons and rings that had previously been distant telescopic targets. Their trajectories then carried them away from the planetary neighborhood and toward the environment beyond the heliosphere.

A record for an almost impossible audience

Each spacecraft carries a gold-plated record containing sounds and images selected to represent Earth and human life. It was not built because anyone expected an alien civilization to find it soon. Its power is symbolic: humanity chose to send a greeting into an enormous unknown.

Distance changes the meaning of home

Images and measurements from deep space make Earth feel simultaneously important and small. The farther our machines travel, the more the story becomes one of perspective—one species learning to see its home as a world among worlds.

The journey continues

The spacecraft will not reach another star system on any human timescale. That is precisely what makes the story profound. Interstellar distances are enormous, and yet we sent something anyway.
