A mysterious 'alien megastructure' star may not be so special after all - NBCNewsMACH
, astronomer Tabetha"Tabby" Boyajian, then at Yale University, and her colleagues found dozens of odd instances of KIC 8462852 dimming by up to 22 percent, with such dips lasting anywhere from a few days to a week. These events did not appear to follow any pattern and seemed far too substantial to be caused by planets or dust crossing the star's face.
These analyses of KIC 8462852 — now nicknamed"Boyajian's star" after its discoverer — raised the possibility that astronomers had detected signs of intelligent alien life. Specifically, researchers have suggested that the star is surrounded by a Dyson sphere, a hypothetical megastructure that is built around a star to capture as much of its light as possible.
Now, study author Edward Schmidt, an astrophysicist at the University of Nebraska-Lincoln, suggests that he may have discovered more than a dozen stars like Boyajian's star.
