KIC 8462852 (aka. Tabby’s Star) captured the world’s attention back in September of 2015 when it was found to be experiencing a mysterious drop in brightness. A week ago (on May 18th), it was announced that the star was at it again, which prompted observatories from all around the world to train their telescopes on the star so they could observe the dimming as it happened.

And just like before, this mysterious behavior has fueled speculation as to what could be causing it. Previously, ideas ranged from transiting comets and a consumed planet to alien megastructures. But with the latest studies to be produced on the subject, the light curve of the star has been respectively attributed to the presence of a debris disk and Trojan asteroids in the system and a ring system in the outer Solar System.

You might get a similar effect if an alien civilisation was periodically launching vessels with huge light sails. Unlike a Dyson sphere this would not require humongously vast amounts of material and the technology required although more advanced than ours today would not be hugely so (we probably know the how today but don't have the material science advanced enough to do it. If we want to send out interstellar probes in the near future we may well develop this ourselves)

You're right though, the universe is a VERY weird place.
Especially if it's spinning around in a bagless Vacuum...

The dimming may be cyclic, indicating the presence of a mass orbiting the star. (Sorry, didn't bookmark that article.) It may take a good long while to confirm that, of course. The mass could be a long way from the star itself.

I gather the issue is that it has an odd pattern if it has one at all.
