Star with alleged ‘Alien Megastructure’ has gotten more mysterious

The mystery dimming of star KIC 8462852 has fueled intensive research among numerous scientists across the globe. A newly published study reveals further information on the possible Alien Megastructure located at mystery star KIC 8462852. Officially, it is the most mysterious star ever discovered in the universe.


In a matter of days, scientists from SETI will know if ET inhabits the mysterious Star KIC


KIC 8462852 has been the center of debate for months after scientists detected what appeared to be a mysterious ‘megastructure’ dimming the light of the star, leading towards speculation that a giant alien megastructure was built around the star.

However, a new study turns away from the probability that  KIC 8462852, aka Taby’s star, is home to an advanced race of extraterrestrials. Interest in the star, located some 1,480 light-years away from our sun in the constellation Cygnus began a couple of months ago when Yale astronomer Tabetha (Tabby) Boyajian and colleagues published a paper on an astronomy preprint server reporting that “planet hunters” discovered extremely weird fluctuations in the light originating from an F-Type Star. The variations in light consisted of dozens of uneven and unnatural looking dips that appeared in a period of 100 days, allegedly indicating that an extremely large number of irregularly shaped objects passed across the fact of the star, blocking the sunlight coming from it.

Media interest in the mystery star went viral when a group of astronomers from Pennsylvania State University published a study that stated KIC 8462852’s “bizarre light curve” was  “consistent with” a swarm of alien-constructed megastructures.

Advanced, spacefaring civilizations might have significant effects on their circumstellar environment, including the construction of planet-sized structures or swarms of objects (see Wright et al. 2014b and references therein). Such “megastructures” might be detectable both by the starlight they block and by the midinfrared radiation they emit after reprocessing this light. (source)

This is why researchers at the SETI Institute turned its Allen Telescope Array on the star in order to see if they could detect any radio signals originating from it. However, a report presented a few months ago found ‘no evidence’ of signals with an artificial origin.

The mystery surrounding the anomalous dimming of KIC 8462852 got even bigger when a Louisiana State University astronomer released a study in January announcing that the brightness of Tabby’s star had dimmed by 20 percent over the last one hundred years –suggesting that a natural explanation could not be applied, and that it is consistent with the idea that an advanced extraterrestrial race was gradually converting material in the solar system of KIC 8462852 into a humongous megastructure that has been absorbing energy from the star for more than a century. Interestingly, this study has been accepted for publication the peer-reviewed Astrophysical Journal.

The mystery dimming of the star was considered by many as evidence of an advanced civilization that had created a humongous megastructure around the star KIC 8462852, in order to harness energy from it. However, researchers say that was only a technical explanation, and there is a different reason behind the changes in the brightness of the star. According to a research team at Vanderbilt University, the drops were caused by changes in the instrumentation, not by changes in the stars’ brightness.

Then, a new study peer reviewed and accepted for publication in the Astrophysical Journal concluded that there is no conclusive evidence that the brightness of KIC 8462852 has been changing over a period of one hundred years. Vanderbilt doctoral student Michael Lund noted that the data was obtained from a unique source:  Digital Access to a Sky Century @ Harvard. DASCH is basically a collection of over half a million photographic glass plates snapped by Harvard astronomers around 1885 and 1993. Lund states that the apparent 100 years dimming allegedly spotted at Tabby’s star might just be the result of observations made through some different telescopes and cameras during the past century.
