π Mystery Signals from Proxima Centauri: Alien Contact or Natural Phenomenon? π½
Since 2019, Australia's Parkes-Murrayang Telescope has been observing our closest star, Alpha
Centauri C, also known as Proxima Centauri, for several months. It basically wanted to find out
whether this star can sustain life on the rocky planet Proxima b, But during this research, an
Australian undergraduate from SETI, Shane Smith, detected a very strange radio signal. And
strange because when Smith shared his observations with his seniors, he saw that the signal
was not like any other natural signal in the universe.
In fact, the structure of that signal was like the artificial signals produced by us. That is, that
radio signal was in a narrow band range of 982 MHz, which is usually used only by artificial
satellites and spaceships. But after this, astronomers thought that maybe our own signals are
bouncing back and forth.
So they studied those signals again. And after that verification, it was confirmed that the signals
we were getting were not at all connected to our Earth. They were coming from somewhere far
away, from interstellar space, even with regular fluctuations.
It can be said that the source of this signal is in a periodic motion. Now, the frequency at which
we have received this signal, we use it in satellites. And as we know that the satellite follows a
periodic motion around the Earth, so this was a hint for scientists that maybe this is the signal
of a satellite created by extraterrestrial life.
And that's why scientists named it Breakthrough Listen Candidate 1, or in short, BLC-1. But
these strange signals were not the only reason why there was so much hype in the scientific
community. The second reason for this hype was also that this signal came from the general
direction of Proxima b planet, that is, from its overall macro direction.
We cannot pinpoint what came from this planet, but we are considering it to be from Proxima b
because this is the planet closest to the Earth, Earth-like exoplanet. And right now, our Red
Dwarf Host Star is circling in a habitable zone of Proxima Centauri. Now, to verify this claim,
Smith and his mentors removed the telescope from the general direction of Proxima b and
surprisingly, as soon as they did this, the signals stopped being detected.
And of course, this cleared all their doubts and this proved that the signal is coming from
Proxima Centauri. But again, friends, as I said, from the general direction, that is, this signal can
be generated from anywhere in the entire Alpha Centauri star system, right? So then how can
we say with certainty that this signal is coming from Proxima Centauri b? In fact, some part of
this star system is hidden from our entire northern hemisphere. You see, because our Earth is
round, we never see the entire sky at once
A very large part of the sky beyond our horizon is always hidden from us like a blind spot. Just
like, for example, people living in the northern hemisphere do not see the sky of the southern
hemisphere and vice versa. That is, there are some stars that we will never be able to see while
living in the northern hemisphere.
So now we are talking about the Proxima Centauri system, which is part of the Centaurus
constellation, which is mainly in the southern hemisphere of the sky. If we have a telescope and
we want to see Proxima Centauri while living in the northern hemisphere, then we will be able
to see this star system only by living in the region of 0 degrees, which is the equator, to 29
degrees, that is, to Delhi. People above this latitude will never be able to see this Centaurus
constellation, even if they have large and advanced telescopes.
But despite this, scientists can say with a good estimate that such an artificial signal may have
come from Proxima Centauri b. And how? So, first of all, we will have to try to understand the
Alpha Centauri star system. There is a binary star system in the middle of this system in which
two dwarf stars like our Sun are circling each other. And our closest red dwarf star, Proxima
Centauri, is circling around this system.
In this entire system, only around Proxima Centauri, these exoplanets have been detected. And
even among them, only one planet falls in the habitable zone of this red dwarf. That is, all in all,
everything is pointing to this that this strange signal is perhaps more specifically coming from
Proxima b planet of Proxima Centauri.
But there is also a problem here. Proxima Centauri is a red dwarf star which is usually quite
unstable. It emits ionizing radiation like X-rays every day.
Now, our Earth also receives X-rays But if we compare the two, then Proxima also receives a
dose of about 500 times more X-rays than the Earth every year. And due to the unpredictability
of red dwarfs, sometimes even more than this. I mean, let's talk about March 2017.
That day, the flares of Proxima Centauri suddenly became 1000 times brighter And if our sun
ever did this, then imagine, even our thick atmosphere will not be able to save us from thirddegree burns. That is, all I mean to say is that we are reaching the conclusion about Proxima b's
habitability as soon as possible. Just think about it.
When the experts were studying the signal of the breakthrough listen candidate 1, when they
were studying the signal, they noticed one more thing apart from the points mentioned earlier.
They noticed that even though the detected frequency in which it has been observed is mostly
used by satellites and spacecrafts. And they eventually also noticed that the signal was detected
for about 30 hours.
Now, this is odd. Because usually such things pass through a telescope very quickly. That is, it is
still not confirmed that the signal was sent by an alien satellite or spaceship.
In fact, a senior planetary astronomer of the SETI Institute, Francis Murchis, has himself said
about this that the existence of two neighboring solar systems in just one corner of our galaxy's
300 million exoplanets, which are possibly habitable, is a shocking thing in itself. And if you
think about it carefully, then it is. After all, how is it possible that our satellites and their
satellites work on the same frequency band range? I mean, we can disprove this by using basic
probability.
Let me explain this with a simple mental experiment. Imagine that you have 100 dice in your
hand. Now, we know that if we roll a die, the probability of any number, let's say 6, coming to
the top is 1 by 6. That is, if we roll 100 dice according to that, then the top number of 16 dice will
be 6. Now, if we add this condition to it that all 16 dice with the same number should fall at the
same place, that too in the first attempt, then what are the chances that what we want will
happen? Obviously, even lower than the previous probability.
That is, what I mean to say is that a perfect outcome is always the result of a random process
which does not repeat easily at the same time, at the same place. And this is the reason that
even though Proxima B planet is quite similar to our Earth, it is still a dicey game to find an
intelligent life there. But perhaps the most recently launched James Webb Space Telescope with
its more advanced and sensitive detectors can help us in this mission.
Actually, just last year, a paper was released in which James Webb Space Telescope and the
soon-to-be launched Lavoier Space Observatory talked about detecting artificial lights on
Proxima B. They claimed that because Proxima B is orbiting so closely with its host star, then
Proxima B will also be tidally locked like our moon. That is, in this case, there is still a possibility
that an alien civilization is floating on its dark side away from the heat. And there, to see in the
dark, artificial lights such as torch, LED tube lights are being used.
Seems logical and interesting, right? Well, nope. Scientists associated with the Breakthrough
Initiative are not convinced by this, and neither am I. Just think about it. The creatures that
evolve in the depths of our oceans, do they need artificial lights? No, they create their own light,
i.e. bioluminescence, there.
Or else, they survive on the strength of their other senses in the absence of light. So, the alien
civilization that has evolved on the dark side of Proxima B, why would it use artificial lights? And
that's why, instead of artificial lights, we should try to detect the bioluminescence of living
organisms in the oceans of Proxima B. This is why scientists associated with the Breakthrough
Initiative are working on a Breakthrough Starshot Project. According to their plan, the probes of
the shape of a kite made of light and strong material will be accelerated with the help of
powerful lasers, with the help of which, these probes will be able to travel at almost 20% speed
of light in the interstellar ocean, And then, these probes will reach Proxima B and send us the
detailed information about its environment and magnetic field.
Meaning, we will be able to know better whether Proxima B is habitable or not. But, until then,
the BLC-1 signal will remain a little doubtful. Just like the 1977 Wow! signal.
Because, the only thing we know about this signal is that this signal came from around 1800
light years away from the Sagittarius Constellation, at 2 Mass 1928-1982, at 2640123, in the
direction of this sun-like star. So, is the hunt for aliens still on? Well, definitely yes. Both the
Wow! signal and the signal from Proxima Centauri are still being researched.
These signals were made by aliens. We can't say this with confidence right now, but this
thought that there could be an extraterrestrial life using our technology in the universe, forces
us to ask, how would the alien life look like? How would it have evolved according to that
particular planet? I mean, when we imagine aliens, we imagine on a big head, skinny body, grey
skin, and big eyes, right? Which is scary, right? But, even more scary would be if the aliens look
exactly like us humans. And then how would we be able to tell who are humans and who are
aliens? And with that said, friends, so what do you think, friends? The signal we are getting from
Proxima Centauri, is it the signal from aliens or not? There is another reason behind it.
