I had to Google this: planetesimal. Learn something new everyday around here.
Too bad it's not a Dyson Sphere, it might make the tin-foil hatters add another layer of tinfoil. Maybe I need to buy stock in a tinfoil company just in case.
It seems "Maybe an alien megastruture" is now in the list of politically correct unsayables (like, and I am totally making things up now, "Trump is not wrong", "Mabye blacks have police problems for a reason" or "Maybe Israel is kinda fascist") One immediately has to declare self-disgust at even have been forced to utter the words, state that anyone delecting in this kind of crimethink is a nutter and make references to tinfoil. And one may still get invited to a ritual disemboweling on CNN.
I don't see why you're keeping things from us. This goes far deeper than you've hinted at. Admit it, you're thinking the two stars are connected by a wormhole.
If they're building a Dyson Sphere, that's fine.
If they're building a Nicoll-Dyson Laser, panic now!
There's nothing politically incorrect about anything you listed except "Maybe Israel is kinda fascist". Everything else is simply incorrect. Politics don't enter into it.
As for the Israel thing, well, Israel is run by horrible people who do horrible things. But "fascism" isn't the correct term. They're their own thing. And yes, I don't understand why it's politically incorrect to say "well, shit, the way Israel's government responds to pretty much everything - both internally and externally - is awful, and a lot of their problems would solvable if they weren't arrogant, xenophobic, nationalistic, control freaks."
Somehow, saying the Israeli government is peopled by monsters is immediately a condemnation of all Israelis or even all Jews (Israeli or not). I don't get how that works, but apparently it's a thing.
The rest of your issues, however, are just wrong. Way before politics gets involved.
"... watching the early business of planet formation ..."
Presumably the next stage is to look out for the spontaneous formation and demise of an innocent sperm whale and a bowl of petunias.
Re: So ...
Oh no. Not again!
Good news then
Means the galactic economy is picking up.
The tourists should be arriving any day now. Time to start learning how to make a really good Pan Galactic Gargle Blaster.
Who needs religion?
The universe is both strange and beautiful at the same time.
Celebrate what we know and what we are yet to know.
Re: Who needs religion?
I think you missed the word "think" in that lovely sentence.
Re: Who needs religion?
We are star dust, as is our world.
I still find that pretty amazing even so.
Big telescopes should be monitoring the frequency domain
Every cluster of pixels should be monitored in the frequency domain.
Obvious is obvious
these planets are just outside the Duracell zone.
watching the early business of planet formation
If you are nearly immortal, as it takes about a million years for much of a change?
More a snapshot of a particular early stage?
Re: watching the early business of planet formation
Yep. And then if we're lucky, we might be able to accumulate snapshots of other stages of planetary formation around a number of similar stars.
In terms of interplanetary observation a lot of cool things are happening. We are in a time when science and technology have allowed the construction of telescopes with previously unimaginable clarity and sensitivity. And given whats on the books things could get even more interesting.
I'm not saying it is a Dyson Sphere, it almost certainly is not, but I don't see why it only partially dimming prevents it from being one? Perhaps the civilisation only needs that much power? Maybe they're working on it but it's not finished? Maybe they ran our of economically viable material to make it with?
Ringworld 'Under Construction'
Yes, I know it's unstable :)
This was good science journalism. I felt I got the essentials without needing to read the paper myself.
Star Constructors, Inc.
There's probably some outfit similar to Magrathea, but dealing in stars, not planets.
And they're clearly sourcing electrical kit from Lucas.
It's Trump's Dyson Sphere
"We're going to build a Dyson Sphere and MorningLightMountain is going to pay for it. Yes he is."
I for one am convinced it is not alien megastructures
The obvious explanation is thousands of alien kilostructures.
I don't get the enthusiasm. What's so exciting/unique/questionable/gripping/enigmatic about a very young star being partially eclipsed by a bunch of amorphous matter in an unpredictable pattern. S'bleedin' obvious that that's what some suns will look like in the early stages of planetary formation, shirley?
Somewhere a monastery has completed writing down the names for God!
