Since the 1960s, scientists have been deliberately sending radio messages into space. The first of these messages was sent in 1962.Morse message‘ has happened. But not every signal sent gives potential beings information about humanity.

Aside from these direct messages to possible extraterrestrial life, all the radio signals we’ve created since the first radio broadcast naturally continue their journey through space. Well, with so many broadcast radio signals When can we get the first return? The answer to this question has been provided by a new study.

The first return message could reach Earth in 2029 at the earliest:

• The Soviet planetary radar that sent the first message into space, Pluto.

The new research, published in the publications of the Astronomical Society of the Pacific, suggests the earliest possible return of aliens. can be obtained in 2029 revealed. It was noted that the first return could be in response to radio messages sent to the Pioneer 10 spacecraft.

Of course, there were scientific calculations behind this answer. Radio messages sent to Pioneer 10 from Earth in 2002 27 million light years away He had passed a white dwarf. The answer was given based on the time it took for a message to reach Earth from this system or other celestial bodies.

Other possible return messages were to the Voyager 2 vehicle in 1980 and 1983, which passed by two different stars in 2007. If your best response to these messages is in 2030 It was calculated that it would reach Earth.

It is also possible that we cannot detect them even though the feedback has been sent:

Although creatures in space have somehow sent us a return signal, according to astronomer Macy Huston, these messages chance of not being detected there is also. Our detection of messages depends on many factors, especially our existing technology and how strong the return signal is.
