Astronomers may have found giant alien 'megastructures' orbiting star near the Milky

[Stardust]

I agree it'd be a great idea for an alien ecosystem, but if a proto-panetary disk with lots of dust would be the ideal breeding grounds for such a thing this system could be problematic. Last I heard, Tabby's Star is older and wouldn't have much in the way of planetary disks, asteroids, or dust/gas clouds.
