KIC 8462852 Star Mystery Just Got Even Deeper

KIC 8462852 displays a unique series of aperiodic dips in brightness, the star faded by 0.2%–20% with duration from a day to weeks — such fast variations of a single main sequence star are inexplicable.

The most intriguing hypothesis but still a possibility was that this star is home to a technologically sophisticated society that has constructed a so-called Dyson sphere that block light from the star. But the Extraterrestrial Intelligence Institute, SETTI, trained its Allen Telescope Array on the star for more than two weeks, and ruled out an alien structure.

Two whole weeks? Well, that settles that. Very interesting article, fun to think about.
