Hear what sounds NASA recorded and sent to aliens in space

Back in 1977, two Voyager spacecrafts were sent on a mission into space with somewhat of a "cultural time capsule" of humanity, which included photographs, notes, and two phonograph records on board with sounds of human life, as deemed by NASA.

Voyager stopped at Jupiter, Saturn, Uranus and Neptune before continuing on beyond our solar system and continuing onward into the abyss of space. NASA's hopes were that if the spacecrafts were to ever encounter alien life, that they'd be able to have a glimpse into human life with sounds recorded on these records.

The sounds that represent human life range from a train to animal calls from birds to chimpanzees to frogs and dogs. The sound of laughter, a mom kissing her child and a heartbeat are also included. Greetings from over 50 different languages ranging from Urdu to Bengali were also added.

Also included were 90 minutes of actual songs that ranged from Beethoven to Mozart and Guan Pinghu to Chuck Berry. Supposedly, it was suggested that The Beatles should be included, but record company EMI denied the request.

Hear the sounds included on NASA's 'Golden Records' below.
