Why would Voyager 1 be the key to finding aliens? | Digital Trends Spanish

On August 25, 2012, the Voyager 1 probe achieved a historic achievement: it left the heliopause behind and became the first to reach interstellar space.

It was 19,000 million kilometers from the Sun and had exceeded the expectations of the engineers who made it and they watched hopefully as it took off from Cape Canaveral on September 5, 1977 (a day like today, 44 years ago).

Today, this NASA probe is still operational. It was designed to study the limits of the solar system, including the Kuiper belt. But he also has another mission: trying to contact some extraterrestrial civilization.

Anyone there?

To this end, both Voyager 1 and Voyager 2 travel with golden records, known as Golden Records, which carry a set of images and sounds characteristic of Earth.

The idea is that this serves as a kind of cover letter in the event that the probe is intercepted by aliens. For this a gold-covered copper disk was used. On one of their faces they recorded 117 photographs of the daily life of our planet and greetings in 54 languages.

Also added 90 minutes of music by famous composers, such as Bach, Mozart, Beethoven and Louis Armstrong, among others.

Instructions for listening to the recordings were included on one of the covers. Thus, to indicate the revolutions that should be used for reproduction, a unit related to the fundamental transition of hydrogen, which is the most abundant element in the universe, was used.

Voyager 1 is the man-made object that has moved farthest from Earth, therefore, scientists believe that it is the human spacecraft that has the best chance of encountering a civilization alien to our planet.

The problem

The only drawback that some researchers raise has to do with the possibility that the messages carried by the discs and capsules are misinterpreted by the aliens, what would happen in that case?

According to the researchers, the anthropocentrism reflected in the discs could make the message confusing for an extraterrestrial civilization, which might think that humans love to argue and that we like to dialogue in incomprehensible jargon.

“The Voyager gold records are a nice representation of how humans want to see themselves, but they are designed to be received and interpreted by something that has the sensory capabilities of an average human,” says Rebecca Orchard of the University. from Ohio.
