Now, Listen to Nasa’s Introduction to Humans – for Aliens

The golden records were made in case either of the Voyager craft had a run-in with an extraterrestrial life-form of the UFO-riding variety; in this proposed scenario, the recordings would serve as a type of greeting card.

The track, of course, comes from the famous Golden Record, a copy of which is aboard each of two of NASA’s most famous spacecraft.

Sounds like Morse Code, dogs barking, a train and even a baby cooing and crying were sent into space on the “Golden Record”, the sounds that were sent on the Voyager spacecraft that launched in 1977, The Next Web reported. Now, these recordings have become available for humans on SoundCloud.

The Golden Records were intended to represent life and culture on Earth, in the hopes a distant alien race might eventually find it (and be into vintage vinyl). “The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space”.

NASA didn’t just vote to put natural sounds on the record.

The phonograph record is a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.

Voyager 2 was responsible for giving people on Earth their first up-close look at Uranus and Neptune, while Voyager 1 continued on a different trajectory that has taken it to its far-off location today.

Carl Sagan, the renowned astronomer and science communicator chaired the committee that chose all 115 images and sounds, including the roaring waves of the ocean, chirping birds, bellowing whales, claps of thunder, and other audio samples.

At this very moment, both probes are now farther away from Earth than any other manmade object.

It’s eerie to imagine hearing these sounds millions of miles from Earth – Voyager 1, after all, is now in a “completely unprecedented” region of space.
