this is the information about humanity that we will send to the aliens

It is not long before the celebration of the 50th birthday of the Arecibo Message, the first attempt to communicate with extraterrestrials. Already in 1974 we wondered what the first message to be sent to space should be, now, some scientists have created a new Arecibo Message, more detailed and also based on critical information about humans and what we know about the universe.

The new message ‘A beacon in the galaxy’ Has been published by a team led by Jonathan Jiang, a researcher at the Jet Propulsion Laboratory (JPL) from NASA.

The human race is defined in terms of physics, biology and mathematics


Through a 13-page study, the researchers explain that this new message should be an introduction to basic concepts of math, chemistry and biology. In addition to defining what should be sent, the best time of year to send the message is also described; between March and October when the Earth is at 90º with respect to the sun and the destination where you want to send, a dense ring of stars near the center of the Milky Way.

“With improvements in digital technology, we can do much better than the Arecibo message in 1974,” the researchers explain.

The way to transmit the information is quite a challenge. Both human languages ​​and the numbers themselves are something specific to humans and possible aliens do not have to understand them. To try to codify these concepts, a bitmap is used, in the form of binary code to create a pixelated image.


This binary philosophy was also used in the original Arecibo Message. In the background is the idea of ​​duality; of right or wrong. Power on/off. Despite trying to offer the information in the most basic way, even so it is not clear that an extraterrestrial race can understand it. In fact, they might not even be able to see the message.

And this is where how the message is structured comes in. Initially a prime number is transmitted, to highlight the artificial origin of the message. Subsequently, our base 10 number system is developed, along with basic mathematical operations. As a result of this, the hydrogen atom and the concept of time are shown, to mark when the message is sent. The next step is to introduce the basic elements of the periodic table and finally the structure of DNA is revealed.

After this there would also be space for an image of how we humans are, with an image of a man, a woman, the map from the eartha diagram of the solar system, our position in the galaxy and the radio frequency used in case they want to reply to the message.


as it points Scientific American, sending these messages is controversial. For being a waste of time and resources, as well as sending information about the human species to a potential outside danger.

Jonathan Jiang has proposed to send this message from the Allen Telescope Array, in California or from the FAST spherical radio telescope in China. After the destruction of the Arecibo, these are the only two radio telescopes that could send such a message. And we say could because at the moment they are only listening radio telescopes, not to send messages. Regardless, Jiang’s team explains that he is negotiating with the FAST team for a possible shipment.
