"Earlier this year, NASA spacecraft Voyager 1 left our solar system after a 35-year journey, carrying with it a golden record containing sounds, images and music from Earth. Its sister craft, Voyager 2, carries an identical record. The records were designed to encapsulate the aural heritage of Earth in 90 minutes - but some preliminary investigation, however, reveals that there a few inaccuracies in the official NASA documentation about the golden records."
