Astronomers don’t think the signal from a nearby star is generated by an alien civilization

At the end of last year, representatives of the Breakthrough Listen project to search for signals from extraterrestrial life reported that they had discovered a mysterious radio signal originating from Proxima Centauri, the nearest star to us. It was spotted by a telescope in Australia and raised questions about its origin.

Astronomers from Harvard published a paper in which they calculated the probability that the signal was generated by an extraterrestrial civilization. They concluded that the chance of such a development of events is 1 in 100 million. That is, you should not count on the first contact.

We have never had a special place or time [within the universe]. Given this assumption, it is extremely unlikely – 1 in 100 million that the star system next to us will be home to a civilization with radio transmission technologies in a specific period of time. 

In other words, if we consider not only the galaxy, but the universe as a whole, it is extremely unlikely that two civilizations will form in neighboring systems at about the same time, which will develop before communication with each other.

Researchers now believe that the received signal is a reflection from the atmosphere of the earth’s radio signal. Maybe at that moment someone opened the door of the microwave and some of the energy got into the telescope. 

The truth is that we started looking for extraterrestrial life very recently and current technology allows us to do this in a limited way, so if there are stunning discoveries, it will take a long time and launch more advanced detectors.
