NASA May Have Found Evidence of an Advanced Alien Civilization in the Cygnus Star System
KIC 8462852
Also known as Tabby’s star, has shown inexplicable fluctuations in its brightness, potentially suggesting the presence of an advanced civilization.
There’s one star that many astronomers, both amateur and professional, are focusing on right now, known as KIC 8462852, or Tabby’s star. The odd nature of this star has led some to believe that it could possibly be a sign of highly intelligent alien life in the Cygnus star system, some 1,280 light years from us. What’s so intriguing about Tabby’s star is that it has been dimming drastically over time and in dramatic fluctuations.
These fluctuations have confounded scientists who have trained a multitude of high-powered telescopes on it, including NASA’s Kepler telescope that originally discovered it. The massive dips that have been recorded in its luminosity have led some to speculate that it could be an advanced alien civilization building a Dyson sphere or swarm around the star, harvesting its energy in a process referred to as star lifting.
Tabby’s star was first discovered by an astronomer at LSU, named Tabatha Boyajian. She is now the head of the Planet Hunters project, a program that searches for exoplanets in other solar systems, especially those that could potentially harbor life. She said that initially the program would have been deemed a success if they found just one exoplanet that fell in the habitable zone, but it has since found more than 50. But the program has received the most attention due to its recent observations of KIC 8462852, which has been exhibiting a phenomenon that scientists can’t fully explain.
What’s so strange about Tabby’s Star is that astronomers have recorded drastic dips in its brightness by up to 20 percent. To put it into perspective, usually a planet orbiting a star will only generate a one percent decrease in light. And while a decrease in brightness of this magnitude is common in young stars, due to their protoplanetary disks, Tabby’s star is not young and a disk has been ruled out from infrared imaging.
Numerous theories have been proposed to define the anomalies in the data associated with Tabby’s star, but none have succeeded in fully explaining what’s going on. Even Tabby, herself, hasn’t ruled out the possibility that it could be an alien civilization. She’s even asked some friends at SETI (Search for Extraterrestrial Intelligence) to aim a radio telescope on the planet to see if they can pick up any signals being transmitted form the area.
Kepler Data for Tabby’s Star
The Dyson sphere, in its different variations, is a concept first theorized in science fiction and made popular by Freeman Dyson. It fulfills a specific criterion on the Kardshev Scale, a hypothetical measure for the level of technological advancement of a civilization. Once a civilization reaches the point that it can harness all of the energy on its planet and others in its solar system, it would supposedly move on to build a sphere around its star, in order to meet its energy needs.
Scientists believe that whatever is orbiting Tabby’s star is within the habitable zone. And while some skeptics say that the strange results are simply incorrect data or bands of asteroids orbiting the star, many of these assertions have been disproven and no theory has sufficiently explained what’s going on.
Another bizarre variable that is evident in the observations is that the light coming from the star is blocked in an asymmetrical manner. If it were a planet or other orbiting body, one would expect to see symmetry. The star also appears to show an overall dimming over time, since observations began in the early 1900s. On average, the star has been dimming by 16 percent every 100 years. This is a highly unusual rate to see a star’s luminosity diminish. This could allow for two assumptions regarding the alien hypothesis. Either they are slowly extracting energy from the star, or they are slowly building solar panels around the star, blocking more of the light that we are able to see.
One might argue that this civilization would have to be moving very quickly to build its Dyson sphere, as Tabby’s star is 1.6 times the size of our sun. Also, one would expect to see an expulsion of waste, likely in the form of radiation, if they were harvesting directly from the star. But one user in the Reddit forum that is dedicated specifically to the star, brought up science fiction novelist, Arthur C. Clarke’s, third law regarding advanced civilizations; any sufficiently advanced technology would be indistinguishable from magic. Essentially, a civilization’s technology, that is advanced to the point of harvesting energy from a star, would be incomprehensible to us.
A Dyson Swarm or Dyson Sphere
Now that our attention is piqued and we have a number of eyes and ears trained on Tabby’s star maybe we’ll be able to discover what’s really going on in the Cygnus constellation. Is it simply a natural phenomenon that will lead us to new discoveries or groundbreaking evidence of a hyper-advanced civilization? Hopefully we will soon learn more.

The Interstellar Cloud is Bringing Space Weather to Our Solar System
Could a thin layer of gas that is as hot as the surface of the sun affect Earth’s climate?
Our solar system, as it moves through space, is traveling through a cloud and potentially experiencing some turbulence. The Local Interstellar Cloud, or the Local Fluff as it is more colloquially referred to, is a thin layer of magnetically charged gas that is 30 lightyears across and as hot as the surface of the sun. So why hasn’t this scorching, nebulous layer of helium and hydrogen caused problems for us yet?
Luckily, our sun, in addition to providing us with the perfect amount of light and heat, has shielded us with a magnetic bubble that is pushed outward by the solar wind. This protective layer is known as the heliosphere and it is like a carapace for our solar system, keeping cosmic radiation and pesky interstellar fluff from fogging over our planets. But what if that protective bubble were breached, allowing for cosmic radiation to enter our solar system? We know that we experience some cosmic radiation on Earth that originates outside of our solar system, causing ozone depletion, unstable isotopes in our atmosphere, and radiation exposure at high altitudes. But we don’t know what the effects that cosmic radiation originating from the Local Fluff might have on us.
Compression of the Heliosphere
While the heliosphere and heliosheath, an area before the boundary to interstellar space, seem to be doing their jobs, there is a possibility that the Fluff is compressing our bubble. As our solar system passes through the Fluff, it becomes oblong, while simultaneously resisting the magnetic bubble of the Fluff. There is also the possibility that there are ‘cloudlets’ of significantly higher density gas within the Fluff. Could these higher density cloudlets make it through the heliosphere and into our solar system?
The average density of the Local Fluff is about 0.3 atoms per cubic centimeter. To put this into perspective, the density of the edge of Earth’s atmosphere is 12 billion atoms per cubic centimeter. At this extremely thin density, there isn’t much reason to worry about it penetrating our heliosphere, but if cloudlets of significantly higher densities came through, they could potentially burst our bubble. According to astrophysicists, these cloudlets could allow more cosmic rays to penetrate our solar system, potentially wreaking havoc on our climate. But we only have another 10,000 years before we pass through the Fluff and our cosmic sky clears.

Interplanetary Climate Change
While anthropogenic causes of climate change are undeniable, there could potentially be additional outside factors at play, according to a Russian scientist named Dr. Alexey Dmitriev. This energy that is being emitted from the Fluff could be affecting all the planets in our solar system. Dmitriev believes that this energy is producing hybrid processes and excited energy states in not just the planets but also in the Sun. So, what are the consequences of this for life on Earth?
Dmitriev states that this excited state could accelerate a magnetic pole shift, it could affect ozone distribution in the atmosphere, and it could generally increase the frequency of catastrophic climate events. While this may sound apocalyptic, he says that this is a regular process and it is natural for Earth’s biosphere to undergo these changes. Essentially, Dmitriev says that these changes will create a necessity for adaptation of all life on Earth.
Whether Dmitriev’s prediction is prescient or overdramatic, we may soon have more data surrounding this phenomenon. NASA’s Voyager probes have almost breached the heliosphere to enter interstellar space, where the Fluff begins. The probes are currently in the heliosheath and able to measure the magnetic field of the Fluff. As they get closer they will hopefully be able to tell us more.
