Astronomers around the globe have still not managed to explain how a distant star in the universe, commonly referred to as Tabby’s star, or KIC 8462852, dims unnaturally and totally randomly. No known astronomical phenomenon can explain why the star decreases in brightness, which has led many experts to speculate whether it is possible that a massive alien megastructure encompasses the star.
Tabby’s star, also referred to as KIC 8462852 has created an unprecedented buzz in the scientific community since 2015 when a team of astronomers discovered that the light of this star often decreased by up to 20% because a large object was allegedly orbiting it.
Now, a new diminution of the brightness has been detected that has led scientists to speculate once again, whether an alien super civilization has created a massive megastructure that is absorbing energy from its star?
ALERT: @tsboyajian star is dipping. This is not a drill. Astro tweeps on telescopes in the next 48 hours: spectra please! wrote Jason Wright Associate professor of astronomy and astrophysics at Penn State University.
The tweet sent to Tabetha Boyajian, the astronomer whose nickname the star owes, woke the astronomic community that immediately set to take advantage of this new opportunity to measure the light of Tabby’s star in a new effort to unveil the mysterious cause behind the dimming brightness of the star.
Tabetha Boyajian responded #TabbysStar is dipping! OBSERVE!! Calling out NASAs’ Kepler, and Hubble observatories among others, adding that the brightness has declined by 2% and it seems to be “just the beginning”.
What causes the enigmatic dimming at Tabby’s Star remains one of the greatest astronomical enigmas of our time.
When astronomers noticed the dimming around the star for the first time, it created great confusion. Tabetha Boyajian, a postdoc at Yale, told The Atlantic: “We’d never seen anything like this star. It was really weird. We thought it might be bad data or movement on the spacecraft, but everything checked out.”
Jason Wright, who recently tweeted about the star’s odd dimming phenomenon says that these structures, or better said mega-structures, could be the product of a highly advanced alien civilization.
As noted by space.com “Scientists have hypothesized that the changes could be due to a swarm of comets passing in front of the star, that they’re the result of strong magnetic activity, or that it’s some massive structure built by aliens. But no leading hypothesis has emerged, so scientists have been eager to capture a highly detailed picture of the light coming from the star during one of these dimming periods.”
Several theories have been put forth trying to explain why the star dims unnaturally.
One such theory has aliens involved, as presented recently by an—Professor Zaza Osmanov—astronomer at the Free University of Tbilisi (Georgia), who assures that if we are looking at an alien megastructure which is causing the star to dim, then our current technology will allow us to identify such megastructures using infrared telescopes.
According to Professor Zaza Osmanov, we could really have found evidence of such alien megastructures and we can even verify the claims using current technology.
Professor Osmanov made headlines in 2016 when he published a study saying that the alien megastructures are more likely to be shaped like thin discs rather than ‘spherical shells.’
In the new scientific paper—published on arXiv—Osmanov writes ‘We have argued that by monitoring the nearby zone of the solar system approximately 64 pulsars are expected to be located inside it.’
