A Gold Record Sent Toward the Stars
Two spacecraft named Voyager were launched in 1977, and both are still traveling far beyond the planets. Each one carries a strange gift attached to its side, a gold-colored record in a protective case. The records are a message in a bottle, thrown into the ocean of space.
A team of scientists and writers chose what to put on them. The records hold greetings spoken in many human languages, from ancient ones to those used today. There are sounds of the natural world as well, such as ocean waves, wind, thunder, birds and whales. A long list of music from different parts of the world was included, along with pictures of people, animals, plants and places, stored as patterns that a player can turn back into images.
How would anyone know how to play a record? The cover has a diagram showing how to use the needle and the turntable, and it uses simple drawings to explain. The record is made of metal, and it was designed to last for a very long time.
Voyager will not pass near another star for a great many years, so it is quite unlikely that anyone will ever find the records. Still, they say something about us. People wanted to share their curiosity, and they hoped for a friendly reply from someone, somewhere.
