Could Giant Alien Structures Be Dimming a Far Away Star? (sciencemag.org)
sciencehabit quotes a report from Science Magazine: Astronomers and alien life enthusiasts alike are buzzing over the sudden dimming of an otherwise unremarkable star 1300 light-years away in the constellation Cygnus. KIC 8462852 or "Tabby's star" has dimmed like this several times before, prompting some researchers to suggest that the megastructures of an advanced alien civilization might be blocking its light. And now -- based on new data from numerous telescopes -- it's doing it again. "This is the first clear dip we have seen since [2013], and the first we have ever caught in real time," says Jason Wright, an astronomer at Pennsylvania State University in State College. If they can rope in more telescopes, astronomers hope to gather enough data to finally figure out what's going on. "This could be the first of several dips about to come," says astronomer David Kipping of Columbia University. "Many observers will be closely watching." KIC 8462852 was first noticed to be dipping in brightness at seemingly random intervals between 2011 and 2013 by NASA's Kepler telescope. Kepler, launched to observe the stellar dimmings caused when an exoplanet passes in front of its star, revealed that the dimming of Tabby's star was much more erratic than a typical planetary transit. It was also more extreme, with its brightness sometimes dropping by as much as 20%. This was not the passage of a small circular planet, but of something much larger and more irregular.
Well does it block 40% of all neutrinos?

That glow radiating from his skin ever since he placed his hands upon the orb still seems kind of creepy. Ever since the Invocation opened up the Portals to the Deep, things just haven't felt the same.

"Some researchers"? Perhaps as a joke. Trillions of stars out there of immense variety and form and the moment someone sees something they don't recognize immediately it clearly must be an alien superstructure... Sigh... It's like the people who see some lights in the sky they aren't familiar with and immediately forget what the "U" in UFO stands for, instead going straight to deciding it must be alien visitors.
And the proper term for "alien life enthusiasts" is "mentally ill person". These are people who for whatever reason WANT it to be an alien whatever and who see aliens and conspiracy theories everywhere with no regard to actual evidence. The pattern recognition parts of their brain are stuck in overdrive and no longer function properly because they are disconnected from the rational parts of their brain.

Seriously, don't mess with Oxygen. It's poisonous.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
For most people, no explanation = God(s). But for a small group of people, no explanation = aliens. You know who you are. Then there is that third group who is willing to admit that we simply don’t know the answer yet, without jumping to extraordinary conclusions.

The answer is, with absolute certainty, "Yes".
If there were aliens and they could make giant structures and those structures were placed between us and some star, it would surely dim.
Whether any of this actually exists is an entirely different question from whether or not it could exist.

The burden of proof rests with the proposal, so you can reject out of hand the premise, "We don't know, therefore aliens."
A Dyson sphere, much less a partial Dyson sphere with sporadic orbit makes no sense. Why build such huge things? With technology so advanced, there are plenty other ways to gets lots of energy. They could harvest cosmic rays or put quantum entangled particles inside stars to generate energy from the paired particles. A lot more fissile material must exist in the parts of a solar cluster that failed to ignite.
However, an armada of spacecraft heading straight here from that star would not only dim it, from our perspective, erratically but also dim more and more of it, as it draws near to us. While also highly improbably, I prefer this alternative as it just seems way more exciting.
I am not an astronomer — not even an amateur one — but is "giant alien structure" really the simplest explanation they could come up with?
And how is it different from the "God made it so"?

Until proven wrong, I say it's Aliens. You can't prove me wrong until you have facts to dispute me
I don't have to prove you wrong. That's not how science works. You don't get to make an unsupported assertion of a positive result and then challenge others to prove you wrong. You made the assertion that it is aliens so you get to be the one to back it up with actual verifiable observations. You have a hypothesis and you get to be the one to run the experiment. For all I know it might be aliens and I'm not saying it is or is not. I'm merely saying that it isn't the most likely among the possible explanations and that we should not favor it until we have better evidence. This doesn't mean I'm ruling out out but merely that the evidence thus far does not even come close to the level needed to support that as a reasonable conclusion.
When the words "NASA" and "alien" appear in the same sentence, the answer is "no".
Counterexample:
"Trump's budget proposal cuts funding of NASA climate missions and eliminates tax credits to illegal aliens "
Except that I'm pretty sure nobody has made that claim.
What has been said is: "What is being observed is consistent with a partially constructed dyson sphere, and thus far it is not consistent with any other explanation we've had".
Now it's possible that this recurrence will allow for more observations, allowing us to learn more - and narrow things down further. That could easily end up with "We're now quite certain that 1300 years ago there was a partially constructed Dyson sphere around Tabby's star". And the likely assumption that, right now, that sphere is complete (or the project failed and it was never pushed past halfway and there's just a few floating bits of scattered construction equipment now.
The thing is - until there is more evidence, even if something else fitted the observations the odds of it being a Dyson sphere is NO LOWER than that other thing. No, it really is not. We have absolute PROOF that intelligent life can exist in the universe. We have absolute proof that SPACEFARING life can exist in the universe. We have absolute physical proof that spacefaring life can CONSTRUCT things in space in the universe.
The absolute proof is that we're here and we've done ALL THOSE THINGS. We've also had the theoretical design for a Dyson sphere for 40 years, we're a long way from building one but there is no theoretical reason whatsoever why, with sufficient technology, it could not be done.
So lets say the new observations STILL fit a Dyson Sphere in progress but ALSO fits a "weird meteor cloud" or something - you have absolutely no grounds to assume the weird meteor cloud is more likely - in fact it's less likely since we've got no evidence that such a meteor cloud can form, no theory for how it may have formed and no evidence for their existence.
Jumping to "There is alien life" would be a mistake, but jumping to "there is NOT alien life involved" is the EXACT SAME mistake.
Right now, the available evidence is consistent with one thing that would require alien life to exist, and not consistent with anything else. This may change - but right now the odds are, very slightly, in favor of aliens.
