Dyson Sphere under construction 1,481 light-years away?

Double digit variations in measured solar output from another star. Astronomers are hard put to offer a natural explanation. Alien engineers at work on a massive structure? It is all happening at star KIC 8462852, in the constellation Cygnus.

The search for exoplanets also really means a search for massive alien megastructures, which will produce a much larger signal than planets of sufficiently massive. So searching for exoplanets is potentially much more rewarding than it first appears.

The $600 million Kepler Space Telescope has been money well spent. We should follow it with more instruments aimed at investigating this star's fluctuating measured output and similar measurements for other stars.

Shades of "Bowl of Heaven".

Probably not, but if one is being built in the same galaxy as us, I certainly would have preferred that it be built a lot further away. One of the things a Dyson sphere is really useful for, is providing enough energy for a truly massive interstellar colonization spree. 1500 light years isn't a lot of breathing room in that scenario; If this is where things stood 1500 years ago, their colonization wave is probably a quarter of the way here, already. Possibly a good deal closer, if they went to the trouble of launching a few really fast missions, to jump start their expansion.

Granted, Dyson sphere is way down the list of probabilities. But this star bears further investigation.

So the good news, contra Brett - if they can engineer megascale objects, they don't need Earth.

regarding the variability - I'm curious if they have detected a periodicity in the signal. If they can, it should be possible to come up with some model of the orbit(s) of the objects around the star.

If there isn't a periodicity (or if it's really, really long), it could be a type of communication.

Can we give this place a proper name instead of KIC 8462852? I vote for Alderaan, or perhaps, That's No Moon.

Some vivid imaginations in the astronomy field.

I would have preferred it allot further away too Brett...especially if Sonny White's warp field experiments are on the right track. If it is possible than they (the advanced aliens)probably already have long had it, in which case 1500ly ain't beans. Are only protection than is that maybe there is too much more interesting real estate in a 1500ly diameter bubble and they just haven't got around to us (yet). Of course:

"where's the exotic matter" might suggest white's theories' are beans; cautiously hoping they are not.

So what if they don't "need" Earth. The question is whether they'd want it.

Actually, were this a real alien artifact, my chief objection would be that our own expansion would be very limited in that direction. As exciting as finding another intelligent species would be, I frankly think it would be better for *us* if we got to be the first one in this galaxy, with nobody to contest our spread. If we want other intelligent species, we can go make them.

I'm pretty sure this isn't an artifict, the signal is too random. Anything that big would have to be built in an organized way.
