In 1977, twin golden records were sent into space on the Voyager 1 and 2 spacecraft. Still sailing through space at nearly 60,000 km per hour, the records contain sound, songs, and images from earth. But how did NASA include images on an analog record? Here, we decoded the audio, and see the images the way that aliens were intended to see them.

Special thanks to Ron Barry for walking us through his own audio decoding process, which got us excited in the story over a year ago. You can read about his own adventure and watch his process produce results in real-time in his own video in the links below:

    What images or sounds would you send to aliens?
  • @Sda-vh1or
    Government: sends Golden discs to space Alien government: hides it from their public
  • @chachcadi271
    Alien 1: why are there so many weird symbols? Alien 2: Did you think they were going to speak English like us?
  • @GmodAdict
    The way I’ve always seen the Golden Record isn’t “a message to the stars” but more a “If we are here no longer, we were still here”
  • I get the distinct feeling that he intended the record to be like a time capsule. We're intended to discover it again after we get very advanced at space travel and be reminded of how we once were.
  • @milkman2143
    Golden Record be like: "John has 2 apples, calculate the mass of the Sun"
  • - Aliens find disc - Aliens didn't figure out how to decode - Aliens google for decoding methods - Aliens watch this on youtube
  • @eclipse4376
    Its so insane how someone actually knew how to create this disc, just every single tiny thing with the very limited amount of tech for the time is so impressive
  • @X39280
    id be terrified if one day this same record gets sent back to us
  • Alien finding the Golden Disc : "Awesome, free gold!" melts the disc
  • @koa_al
    The aliens after finding this: Hey doesn't this look like the Golden Disc we sent a thousand of years ago?
  • @joshuekz7243
    Imagine in the future if the aliens that found the record managed to decode it, and when they arrive to our system, the sun would already be a red giant and the earth was eaten by it, that will be depressing.
  • @stefanmaster2099
    fun fact: when our star burns out, the golden record may still exist and will be the last relic of humanity
  • @mont9150
    this is the hardest easter egg so far in the universe
  • @Julio-wr7pz
    Alien: "What do you think this is?" Other Alien: "I don't know, let me open Excel real quick."
  • This man should put this on a satellite. As a tutorial for aliens who can't figure how to decode the Golden record
  • @MarsFKA
    A billion years from now, when everything that we have ever built on Earth has crumbled into dust, when the continents are changed beyond recognition, and our species is unimaginably altered, or extinct, the Voyager Record will still speak for us. Carl Sagan
  • @Leafyu29
    Plot twist: this ends up on a planet where there are other humans and it becomes that planet's biggest mystery.
  • @colony8286
    Nasa creates a map were earth is, aliens visits, military shoots its down Aliens: man it was a trap
  • @F-35BLightningII
    One day, we are going to get something similar here on earth. And when decoded, it states. Be quiet, or else they'll find you to
