In 1977 NASA launched Voyager 1 and Voyager 2 to study the outer Solar System. Once they fly past the outermost planets, they would continue with the Voyager Interstellar Mission. Both of these craft have a golden phonograph record on board, containing pictures and sounds from Earth on one side. On the other side there are symbolic directions for playing the record and a diagram showing the location of the Sun, using 14 pulsars in known directions from our Sun and their pulse frequencies depicted as a binary code. Using the binary code of each pulsar (1 is a note and 0 is silence), I converted them to 14 separate audio tracks. For the pitch of each track I used the distance of the particular pulsar to the galactic centre. The song that you hear is like an audio address of our Solar System.
