The mysterious alien megastructure star may not be that special after all



A mysterious star whose multiple bouts of darkening may be due to "extraterrestrial megastructures", according to some researchers, may now have more than a dozen colleagues exhibiting such mystifying behavior, a new study shows.

In addition, exploring all of these stars can help solve the puzzle of their stunning vibration, says the study's author.

In 2015, scientists noticed unusual fluctuations in light from a star named KIC 8462852. This otherwise normal F-type star, which is slightly larger and hotter than the earth's sun, sits about 1

480 light-years from Earth. , in the constellation Tsignus.

These events do not seem to follow any pattern and seem too substantial to be caused by planets or dust crossing the star face.

These analyzes of KIC 8462852 – now nicknamed "The Star of Boyadzhian" (former Tabi star) after its discoverer – raised the possibility for astronomers to find signs of intelligent extraterrestrial life. In particular, researchers suggest that the star is surrounded by a Dyson sphere, a hypothetical mega-structure that is built around a star to capture as much of its light as possible. The mathematician and physicist Freeman Dyson suggested that such mega-structures could help power an advanced civilization. (Science fiction often depicts Dyson's spheres as solid wrappers around stars, but megastructures could also be globular swarms of giant solar panels.)

The mega-structure hypothesis is near the bottom of most astronomers' lists these days word for Boyajian's star, however; further analyzes indicate more prosaic explanations, such as dust clouds or comet fragments. However, scientists have not yet nailed the exact cause of the strange blackout. The answer remains partly elusive because Boyajian's star looked unique; there were no known colleagues to provide additional clues that could help the researchers solve this cosmic mystery.

The study's author, Edward Schmidt, an astrophysicist at the University of Nebraska-Lincoln, suggests that he may have discovered more than a dozen stars like the Boyadjian Star.
