Yeah... but, that suspicion is based on a "smoking gun"...

...

A new study using NASA's Spitzer and Swift missions, as well as the Belgian AstroLAB IRIS observatory, suggests that the cause of the dimming over long periods is likely an uneven dust cloud moving around the star. This discounts the "alien megastructure" notion and other exotic speculations. 

The smoking gun: Researchers found less dimming in the infrared light from the star than in its ultraviolet light. Any object larger than dust particles would dim all wavelengths of light equally when passing in front of Tabby's Star. 

"This pretty much rules out the alien megastructure theory, as that could not explain the wavelength-dependent dimming," said Huan Meng, who did the research as part of a postdoctoral fellowship at the University of Arizona. Meng, who graduated with a PhD from the UA's Lunar and Planetary Laboratory in 2014, is the lead author of the new study published in the Astrophysical Journal. "We suspect, instead, there is a cloud of dust orbiting the star with a roughly 700-day orbital period."

So what is your contention with "the smoking gun"?

The authors of the scientific paper which reveals a dust-like spectrum for the gradual, long term dimming, are careful to admit that this does not explain the star's large, intermittant dips in brightness. Dust that remains in dense clumps, which this sort of dimming would require, is difficult to explain as an astrophysical phenomenon.

what about aliens instead of alien megastructure?what about some sort of space algae,or a swarm of creatures that feed of the energy of the star.unlikely,but haven't heard that theory.

So the conclusion definately nothing to do with aliens? Shame... oh well,

It's definitely unusual.but without further evidence and study it's all just guess work.whos to say it's not an alien race throwing a massive party

Well poop, would have been exiting if it really had been some alien mega structure.

Of course this was always the most likely outcome, still it's fun to hope and be exited.

The simplest most logical explanations generally pan out.

It's just like our sun. you can see it in the daytime and can't see it at night. So Where's the mystery?
