We May Have Discovered an Alien Civilisation!

We may have found an alien civilisation light-years away! It looks like there are intelligently built structures orbiting another star in our galaxy. This is better than finding water on Mars! If these are Dyson spheres that we have found, then the aliens are far more advanced than us--Type 2 on the hypothetical Kardashev scale.
But seen as the star the structures orbit is close to 1,500 light-years away, what we are seeing today is the distant past; the aliens could, at present, be on their way to becoming Type 3 (beginning to harness energy from the galaxy)--if they haven't gone extinct. If they ever visit our planet, they will look like gods to us. 8-)
For those who reckon this is a sensationalist headline, I invite you to read Tabetha Boyajian's data--we are talking about NASA astrophysics here--detailing rotation period anomalies of the KIC846282 system. It is no wonder that scientists are taking the alien civilisation hypothesis very seriously: Tabby star's astronomic light curve suggests alien megastructures akin to Dyson spheres--possibly something like an epic system of solar panels placed around the yellow dwarf!
Tabby's star--which is a candidate for gravitationally holding Earth-like exoplanets--is about 454 parsecs away from us and cannot be seen by the naked eye; its unusual brightness changes were first thought to be caused by disintegrated comets in orbit, however, this hypothesis is loosing its ground as the light frequencies have become oddly irregular over time. Here's an excerpt from The Independent:
'The analysts tagged the star as "interesting" and "bizarre" because it was surrounded by a mass of matter in tight formation. This was consistent with the mass of debris that surrounds a young star just as it did with our sun before the planets formed. However, this star was not young and the "debris" must have been deposited around it fairly recently or it would have been clumped together by gravity--or swallowed by the star itself.'
SETI is going to see if they can detect intelligent signals from KIC846282; taking the Drake equation into account, by the way, just because a civilisation is highly advanced doesn't necessarily mean it will have the desire to reach out to galactic neighbours. (Even if they are humanoid like us--which is a possibility considering that they would have evolved in Earth-like environments with similar Darwinian selections.)
