Weird star - strange dips in brightness are a bit baffling

Currently, the article title is: "Did Astronomers Find Evidence of an Alien Civilization? (Probably Not. But Still Cool.)". I found it a bit too link-baity and flag-inviting for what is a pretty interesting article from Bad Astronomy, therefore used a title decoded from the URL. Let me know if I should change it back, or to something else.

Yes, there are aliens in the article - because the dips in brightness are so baffling, that there are suggestions from serious astronomers that we may be - unlikely, but still - witnessing construction of a megastructure.
