Aliens of Proxima Centauri?

Astronomers detected an interesting signal from the location of a star close to us with radio telescopes in the Australia Parkes Observatory. The strange thing is that the signal received is in the frequency range that cannot occur by the natural ways, that is why the possibility of extraterrestrial life came to the fore again.

Short Info about Proxima Centauri

With a distance of 4.2 light years, the Proxima Centauri star is known as the closest star to the solar system. There are also 2 exoplanets in the star's orbit. One of these exoplanets, Proxima Centauri b, is located in the habitable zone that allows water to remain in a liquid status. This information raises the possibility that intelligent beings could exist on this exoplanet.

What is the signal coming from here? What are the possibilities?

Signals in this frequency range can be caused by human-made objects such as satellites. Therefore, it is possible that the signal was caused by one of the satellites orbiting our world. Because there are about 2700 active satellites in orbit of our world and these satellites send data to the Earth continuously. However, it is not even certain that the signal is coming from Proxima Centauri. This is because the signal may be transmitted from another source in line with Proxima Centauri, but behind it.

Even when we assume that the signal is coming from this area, other possibilities meet us. For example, in our solar system, some radio pulses can originate from Jupiter due to its large magnetic field. In other words, a planet which has a very strong magnetic field in the Proxima Centauri region may also be causing these signals. However, this possibility is highly unlikely to be true. Because if we were to put Jupiter in the area where Proxima Centauri is located, the radio signals originating from Jupiter's magnetic field would be 1,000 times weaker than even the weakest signal that ever came to the world. In summary, we cannot say that this is impossible, but we can describe it as a very low possibility.


The 982 megahertz frequency from Proxima Centaturi is not a strong enough signal to come from a quasar, black hole, or such a celestial body. As you can see, the possibilities are quite high, but even though we would like to think that the signal indicates smart life, this is very unlikely. One of the best examples of this is FRBs. FRB signals are radio signals that can emit very high energy signals within milliseconds, and in just milliseconds they can generate more energy than the sun emits in three days.

Where these high-energy radio signals come from and how they are formed has been one of the most curious topics for astronomers for over a decade. Among the possibilities that caused the signals were black holes, supernovae, neutron stars, and even "aliens" as thought in the signal from the Proxima Centauri region. By April 2020, about 50 FRB signals had been detected, and these signals were reaching Earth from millions of light years away. However, in April 2020, it was detected for the first time that a FRB came from our galaxy, the Milky Way. So astronomers focused on this area and discovered that the sources of the signals were magnetars with very strong magnetic fields. Because magnetars, which we can define as the strongest magnets of the universe, have enormous magnetic fields and can generate strong signals in very short periods of time.

The source of these signals, whose mystery had not been solved since 2007 and was thought to come from aliens, was finally identified.

To summarize; Maybe some kind of exoplanet's magnetic field that we haven't discovered yet, may be sending signals in the low frequency range. Or, the signal that we think comes from Proxima Centauri may be transmitted from a local source, as in the microwave example. So we do not know enough about the signal from Proxima Centauri yet; However, the fact that we do not know the exact source of the signal yet does not mean that it came from aliens.
