The Recent Observation
Recently astronomers in Chile has noticed a star in the faraway sky of the south which was seen flickering oddly. Though, it seems to be some cloud that is orbiting around it yet there is no confirmation to this. This star is thought to be reminiscent of two other substantial astronomical objects, one of which harbors a planet with rings 200 times larger than those of Saturn. The other one, though having less probability is supposed to be encircled by “alien megastructures.” This newfound star would help throw some light on this mystery.
At the beginning of the year 2010, a project was introduced by Via Lactea survey. According to the project they were planning to create a 3D map of different stars close to the vicinity of Milky Way’s center.
While working on this project, Astronomer Robert Saito while analyzing the data observed eruptive outbursts from millions of stars, however, one striking observation was of a star that grew dim in the year 2012. This finding was published in the Monthly Notices of the Royal Astronomical Society.
This star is known as the VVV-WIT-07, looks older and much redder than our sun. It is certain that in the summer of 2012, the brightness of this star faded away for about 11 days and then dropped sharply over the next 48 days. That meant that something was blocking more than ¾th of the star’s light coming towards the Earth. Now the question is to find out the reason behind this.

Eric Mamajek, an astrophysicist at the University of Rochester, suggests that a considerable number of large objects must be blocking this much of starlight. According to Mamajek, the strange signals coming from VVV-WIT-07 may be due to the clouds of materials passing between the Earth and the star. However, he did not say it confidently as he suggested that further observations were necessary to come to a proper conclusion.
Tabetha Boyajian, an astronomer at Louisiana State University, had agreed to this. He had once worked on the research of Tabby’s star that showed significant dimming. It was explained as the outcome of an alien civilization building an artificial structure that soaked up the start’s light or by the warm of comets or fragments from a shattered planet. However, nothing could be proved so far, and researchers are still busy trying to figure out the exact cause of the strange dimming of Tabby’s Star.
Usually, the light curve is used to study the dips by plotting the intensity of a star’s light over time. The light curve of J1407 revealed that its rings could block about 95 percent of the stars light. Similarly, the light curve of Tabby’s star suggests that any object orbitting around it would prevent around 20 percent of the star’s light. So it can be assumed that the dimming effect of VVV-WIT-07 might be due to a similar reason.
According to the research done and the observations made by Saito in 2016, it can be assumed that the star would continue flickering into 2019 while also displaying some more dimming events throughout the year. This would happen as the mysterious light blocking material would continue orbitting around the star. If these could be proved then only similar mysteries would be solved.
Boyajian says that if both the stars are studied simultaneously, then the theory can be proved easily. Moreover, if the same natural process causes both the dimmings, then the possibility of an artificial construction project can automatically be negated.
