Golden RecordAre we alone in the universe? Who knows; but it would be naive of us to think so. And what would happen if we discovered we´re not alone? If we ever did encounter an alien species, the first stumbling block to overcome would be communication. We´d have to find a way to understand each other’s languages.

Two unmanned probes were launched by NASA over 30 years ago: Voyager 1 and Voyager 2. They were sent to investigate the larger planets of Jupiter, Neptune, Uranus and Saturn, beaming back images and data for us to analyse. They continued travelling further and Voyager 1 is now 10.5 billion miles away from Earth and Voyager 2 is 8.6 billion miles away. The mission has been successful so far…with one odd occurrence a few years ago.

Despite no previous disruptions, on 22nd April 2010, Voyage 2 suddenly started transmitting odd messages. The usual data streams which had been consistent for three decades were suddenly being transmitted in an unknown data format. The scientists at NASA´s Jet Propulsion Laboratory (JPL) were unable to fathom out their meaning or the reason for this unexplained change as all of the other systems on the probe seemed to be functioning correctly. Hartwig Hausdorf, a German academic, concluded that alien life forms had taken over the probe in an attempt to make contact with us. Seem too far-fetched? Maybe not…

The space probes were never just intended for exploration. Both of them were fitted with a Golden Record, a phonograph record containing sounds and images of life on Earth in 55 languages, intended as greetings for extraterrestrial life forms or for humans in the future. So maybe the possibility of making contact with alien life isn´t such a stretch of the imagination after all. Whether you´re hoping for a future exchange of dialogue with an extraterrestrial, planning on striking up a conversation with a resident alien of the human kind, or simply interested in the challenge of learning a new language that´s alien to you, get out of your comfort zone and take a leap into the unknown!
