But there’s also been speculation that Kepler may have the ability to detect more than natural phenomena; if they’re out there, Kepler may also detect the signature of artificial structures orbiting other stars, Discovery reports.
Among the likely natural causes of the star brightness dimming outlined in a paper submitted to the journal Monthly Notices of the Royal Astronomical Society and made available on the arXiv preprint service on Sept. 11, astronomers looked into debris from a possible planetary collision, the presence of circumstellar rings, starspots, and a clump of comets. All possibilities were investigated, but all were unsatisfactory, except for the latter.
The comet clump explanation seems to answer many of the mysteries about the strange transit signal. A nearby star, only 1,000 AU from KIC 8462852, could have caused some gravitational perturbations during close approach, possibly sending a swarm of comets toward the star, blotting out up to 22 percent of the star’s light from Kepler’s view.
Imagine an advanced civilization that’s well up on the Kardashev scale and has the ability to harness energy directly from its star. This hypothetical alien civilization may want to construct vast megastructures, like supersized solar arrays in orbit around their host star, that could be so big that they blot out a sizable fraction of starlight as they pass in front.

And four others.😃
I am also excited,though....
Unless it's a giant fleet of warships headed straight for us.
