Since its discovery in 2016, Tabby’s Star has remained an inexplicable phenomenon in our universe. Read to learn more about how astronomers are trying to figure it out.
In 2016, word came out about the discovery of a downright strange astrophysical object, somewhere in the constellation Cygnus. It wasn’t another Earth, but rather, a star.mission when they encountered the star, officially named KIC 8462852. And it was an oddball. It randomly dimmed, like a flickering lightbulb, and could stay that way for several days. It fluctuated intensely and erratically, sometimes dropping up to 22 percent in brightness.
But any other stars, exhibiting similar behaviors, all had explanations astronomers could see and detect – not Tabby’s Star. When Wright first learned of the star after Boyajian gave a talk at his university, he’d been working on his own paper imagining what Dyson Spheres might look like. What he saw in the data seemed to echo what he’d been reading and writing about.When SETI scientists investigated the star, they couldn’t find any evidence corroborating the theory. Of course, aliens were only one unlikely idea. Finding a natural explanation that fits everything remains elusive.
But it didn’t work all the way. Dust could conceivably be filtering starlight, but it still didn’t produce any infrared excess. There was also the problem of the long-term fading. As for where the dust around the star might’ve come from, or how it explains the long-term fading, Wright says bluntly, “No, I don’t know what’s going on.”
