The Curious Case of Tabby’s Star: Three new ideas have emerged to explain Tabby’s Star, officially known as KIC 8462852, but the jury’s still out on what’s really causing the weird behavior of our galaxy’s most mysterious star.

The star KIC 8462852, also called Tabby’s Star, has been the subject of intense debate since May’s announcement that this unusual F-type star, located in the constellation of Cygnus, was dimming once again.
Observations at Fairborn Observatory detected a 2% drop in brightness between May 19th and 21st, and a host of ground- and space-based telescopes jumped in on the action.
Ever since the first public report of the mysterious star in 2015, numerous theories have been proposed to explain its bizarre behavior — sometimes the star’s brightness dims by a couple percent, like last May, but sometimes it dips by as much as 20%, and for days to weeks at a time. Not to mention the long-term fade that appears to be plaguing the star. So it’s no surprise, perhaps, that many proposed explanations have failed in their attempts to explain what’s going on.
