VOYAGER GOLDEN RECORD
The content of the Voyager Golden Record was selected by a NASA committee chaired by Carl Sagan of Cornell University.
The intention was to make a permanent record of humanity. This record, if found by an extraterrestrial intelligence, would give a clear picture of our ways of life, our artistic endeavours, and our current state of scientific progress. Music, photos, and more were encoded into the golden grooves of the phonograph.
A copy of the record was placed on both Voyager 1 & Voyager 2, deep space probes that NASA launched in 1977 to explore our solar system and beyond.
As of today, both Voyager 1 & 2 have left the solar system and are still operating in the cold vacuum of space.
