The mysterious Alien Megastructure star may not be that special



A mysterious star whose repeated obscuration could be traced to "alien megastructures", according to some researchers, may now have more than a dozen analogues with similar mystifying behaviors, a new study finds.

Exploring all these stars could help solve the mystery of the confusing flicker, according to the author of the study.

In 2015 scientists noted unusual light fluctuations in a star named KIC 8462852. which is slightly larger and hotter than the sun, is located about 1,480 light-years away from the earth in the constellation Cygnus.

as the researcher data from analyzed The NASA's Kepler Space Telescope, the astronomer Tabetha "Tabby" Boyajian, then at Yale University, and her colleagues found that dozens of KIC 8462852 cases declined by as much as 22 percent, with such burglaries just a few days to a week. These events seemed to follow no pattern and seemed too substantial to be caused by planets or dust that permeated the star's face.

These analyzes of KIC 8462852 – now called "Boyajian's Star" (formerly Tabby's Star), according to its discoverer – threw away the possibility that astronomers had discovered signs of intelligent extraterrestrial life. In particular, researchers have suggested that the star is surrounded by a Dyson sphere, a hypothetical megastructure built around a star to capture as much light as possible. Mathematician and physicist Freeman Dyson suggested that such megastructures could help energize an advanced civilization. (In science fiction, Dyson spheres are often depicted as solid shells around stars, but the megastructures can also be spherical flocks of giant solar collectors.)

The hypothesis of megastructures is now in most astronomer lists relative to the star from Boyajian in the end, however; Further analysis has pointed to more prosaic explanations such as dust clouds or comet fragments. Nevertheless, the scientists have not yet discovered the exact cause of the strange dimming. The answer is sometimes difficult to grasp, as Boyajian's star seemed unique; There were no known counterparts that could provide additional clues to solving this cosmic puzzle.

Study author Edward Schmidt, astrophysicist at the University of Nebraska-Lincoln, suspects that he has discovered more than a dozen such stars Boyajian's star.
