An “alien megastructure” known as “Tabby’s Star” is becoming more bewildering as scientists try to learn more about it.
NASA’s planet-seeking Kepler space telescope has given out fresh and analyzed observations showing that the star KIC 8462852 sometimes took dramatic dips in brightness, a perplexing observation for astronomers.
The star KIC 8462852 also dimmed overall during the last few years.

According to Space.com, study lead author of the California Institute of Technology in Pasadena, Ben Montet, said, “The steady brightness change in KIC 8462852 is pretty astounding.”
“Our highly accurate measurements over four years demonstrate that the star really is getting fainter with time. It is unprecedented for this type of star to slowly fade for years, and we don’t see anything else like it in the Kepler data.”
The causes of the dimming of the “alien megastructure” has not yet been identified. The event, in actuality, made people ponder on the concept of the “Tabby’s Star” or KIC 8462852 being a massive alien construction drifting around in the constellation Cygnus.
Josh Simon and Montet went over Kepler’s observations and came across that fact that beyond the changes in brightness, the star “faded slowly and steadily” within a four-year period.
“We thought that these data could confirm or refute the star’s long-term fading, and hopefully clarify what was causing the extraordinary dimming events observed in KIC 8462852,” Simon informed in a press release by Carnegie Institution.
According to CBS News, the new observations regarding the “alien megastructure” have not cleared up the air but have enhanced the mystery to a greater extent.
The orbiting of a planet around “Tabby’s Star” was the impossible factor that causes these significant brightness dips.
However, scientists have given alternative explanations, which include the possibility that there might have been a planet or a family of orbiting comets that have broken up. Scientists also stated that there might be some unknown object in deep space between the star and Earth causing the dimming.
