The two research teams are preparing messages to communicate with the supposedly intelligent extraterrestrial civilization in space. They will also send the location of the earth.
According to two scientists at the University of Nottingham, our galaxy contains at least 36 civilizations of intelligent extraterrestrials, a number thanks to a modified version of the famous Drake equation. Moreover, it is most likely considered that there is life among the 300 million potential habitable planets present in the Milky Way, and that it could evolve into intelligent extraterrestrials in at least some cases. To date, however, we have not found any clues in space to prove the existence of intelligent extraterrestrials; We live in a state of depressing loneliness that experts call “the great silence.” Nevertheless, we have long been committed to communicating with speculative civilizations.
METI’s most interesting project, communicating with extraterrestrials through special messages, is undoubtedly the famous “Message from Arecibo”, sent to Puerto Rico by the Arecibo Observatory in 1974, tragically destroyed by a recent earthquake. In this case, the scientists created a radio message based on binary code to provide basic information about humans, biology, mathematics, etc. It was sent to the globular star cluster M13, 25,000 light-years from Earth, which is the richest of the stars and, therefore, probably also to the planets inhabited by extraterrestrial civilizations. In terms of huge distances, a potential extraterrestrial reaction could reach us in thousands of years. It is even less likely that extraterrestrial civilizations could get their hands on messages from Pioneer and Voyager spacecraft – such as the famous “Golden Record” – and react to them.
As detailed in a conversation with Professor Chris Impe, a professor of astronomy at the University of Arizona, the two teams of scientists plan to send a new message to the supposedly “neighboring” extraterrestrial civilization. The first will be sent by researchers at the Gunhili Satellite Earth Station in England to the Trapist-1 Star system, which became an international headline in 2017 when NASA unveiled it at a worldwide press conference. In fact, seven Earth-like planets orbit this star, three of which may contain liquid water (they are in habitable zone). They are currently the best place to search for living creatures (and intelligent life) in space, which is why British scientists chose them as their target. Since it is “only” 39 light-years from Earth, a potential extraterrestrial reaction could occur in less than 80 years. The message will be sent on October 4, 2022.

In 2023, “The Beacon in the Galaxy” will be sent, a message in binary code inheriting the Arecibo message. To send it, scientists will use the world’s largest radio telescope, a giant 500 meters in diameter located in China. This time, the target will be millions of stars at the center of the Milky Way, between 10,000 and 20,000 light-years from Earth. The post will include biochemical makeup of life, stylized images of women, men and DNA, information about the solar system and not everyone can believe, even details about the location of the earth. The TRAPPIST-1 message will also indicate the location of our planet. According to some scientists, like the late British astronomer Stephen Hawking, aliens have a bad idea about the position of the earth. If they are hostile and equipped with advanced technology from us, they can actually reach out to us, attack us and destroy us as Hollywood’s most classic (just look at how we treat other living creatures on our planet). According to others, however, intelligent people can understand the concept of cooperation and therefore “come to peace” with the only curiosity we have. There are currently no international rules on these messages, so scientists will continue to communicate, prepare and transmit future responses in the hope of not making a catastrophic mistake for all of humanity.
