In the Milky Way Galaxy, 36 Intelligent Alien Species Can Contact Us From 17,000 Light Years

Scientists have calculated how many active civilizations there may be in our Galaxy and have come to the conclusion that there are 36 of them and that they are able to communicate with us using radio waves. But do not rush to rejoice, scientists gave explanations that disappointed everyone.

According to experts from the University of Nottingham, there is an assumption that intelligent life develops on other planets in the same way that it developed on Earth. The alien populations considered in this study were named by British researchers from the Networks Communicating Extra-Terrestrial Intelligent (CETI) project as civilizations characterized by the ability to transmit radio waves. The cited study was published in The Astrophysical Journal.

Scientists, drawing a parallel between the evolution of life on Earth and similar biological development on other worlds in the Milky Way, arrived at the theory that in our galaxy we need to look for at least 36 extraterrestrial civilizations similar to our own, specialized in sending radio signals to the space.

36 Intelligent Alien Species

These 36 extraterrestrial civilizations represent, in the opinion of experts who participated in the study at the University of Nottingham, the so-called astrobiological Copernican limit.

More information about the researchers’ calculations was provided by Christopher Conselice, an astrophysicist at the British University. He said:

“Our new research suggests that searches for intelligent extraterrestrial civilizations not only reveal the existence of how life forms, but also give us clues as to how long our civilization will last.

If we find that intelligent life is common, it would reveal that our civilization could exist for much longer than a few hundred years.

Alternatively, if we discover that there are no active civilizations in our galaxy, it bodes ill for our own long-term existence.”

In particular, the definition of the aforementioned limit stems from the assumption that planets like Earth are orbiting a star in the habitable zone and have the correct distribution of elements, intelligent life that communicates by radio develops in 4,500-5,500 million years. years after the formation of the planet.

According to the results of the study, 36 civilizations should be evenly distributed throughout the Milky Way. However, the academics themselves immediately smothered mild enthusiasm for the next “close contacts of the third kind”.

In light of published estimates, the closest alien civilization to us will be at a distance of 17,000 light-years from Earth, which will make any radio link between a hypothetical celestial body and our planet impossible.

In addition, the same probable extraterrestrial populations can inhabit the planets located close to the red dwarfs, that is, stars completely different from our Sun, as they are much less powerful and extremely unstable.

Consequently, scientists conclude that there is a high probability that we are indeed the only active civilization in the Milky Way.
