We decoded NASA’s messages to aliens by hand

May 29, 2019 By

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:

    The recording is supposed to be about an hour long, but the Soundcloud file is only about 15 minutes. Does anyone know where to get the rest of it?

    They also want to fool the aliens to think the Earth is round, or is this just a scheme to solidify our belief that the Earth is round? Hmm.

    I think their signaling alien beings the wrong way by sending the golden record because they reside in dark matter in the next dimension to our left not in space in my personal opinion i beleave humanity has to make them selves aware of their presences before they reveal themselves to mankind when you start making yourselves aware you will witness your intelect increase you will be more awakened and able to observe the world and human behaviour from a higher concious you will develop an alien like mental and physical behaviour you will witness this change happen before you and you will start understanding what our next evolutionary step is because everything humans do like partying consume alcohol and all types of pleasures and desires like material objects and etcetera you will see that as mankinds immaturity i know because it's happening to me at only 26 and i always talked about gangs and violence now i see what humanity must do but ill keep it to myself make yourselves aware open your minds i encourage it you wont be disappointed ones you make yourselves aware i repeat.

    The part NASA hasn't told anyone is, if you get both records there are "two turntables and a microphone" on each space ship
