I can't believe no one has posted this yet:

TL;DR: We looked at a bunch of stars and found 234 -- that's right, two-hundred and fucking thirty fucking four -- stars that appear to have aliens trying to contact us with optical beams.

Go nuts.

Apparently our big "human" achievement is nuclear power. So we'll probably relay the signal back by launching a half dozen nukes into orbit.

>Borra and Trottier said that the signals are likely from an intelligent alien civilization manipulating the stars to send a message and make us aware that they exist.

Sounds awfully optimistic. If this reflects the team's general view of alien life then this might just be a case of people seeing something that isn't there. Let's see if this shit gets replicated by someone else, then we can go nuts with excitement.

Why would aliens do something like that to telegraph their presence anyways? Sounds awfully complicated and obscure. Maybe it's a way of communicating between themselves or something, but still that shit can be achieved with a laser. Hell maybe it's the 'artwork' of some rouge alien AI or whatever.

Well yeah, everyone is waiting for the replication. Even this much is worth celebrating, this is the biggest stir in SETI since, well, pretty much ever (unless we count our recent 'alien megastructure' experiences.) It's like I can get excited when a movie is announced even if I'll be more excited when it actually comes out. Even if it turns out to be nothing, the fact that we're getting this much better at looking is big news.

And, presumably, they are using lasers to send the signals -- how else would you send a coherent optical signal over such a great distance? I don't think it's that strange, it's actually probably the simplest form of active SETI one could practice. Just create a satellite or ground based array containing thousands of laser beams, each aimed at every star within a certain radius, in the hopes someone gets the message. It would be a lot harder to do with a radio telescope, which may explain why there would be so many optical signals but we've never gotten a radio signal. Such tech would be trivial for a 1K or > civilization (which I would assume these must be.)

If I understood it correctly, the supposed signal is not lasers but 'spectral modulation'. Whatever that means, I take it that it's the light from the stars themselves that's supposed to be the signal. The fact that over 200 stars seems to show the same phenomenon either means it's an incredibly advanced interstellar civilization, or an as of yet unknown natural effect.

This seems a little bit far fetched. There's plenty of astronomical/astrophysical problems still unsolved, so calling it already and saying it's aliens seems a little bit premature.

Agreed, probably more likely it's a yet-to-be understood stellar phenomenon, I mean would aliens seriously spend the time and resources necessary to modify STARS just to send messages? There has to be more efficient methods of stellar communication than modifying an entire fucking star. Like just the amount of engineering to construct a device able to modulate a stars light output seems retardedly complex for communication
Thy being said, maybe it is aliens and the fluctuations in signals has to do with some sort of Dyson sphere like device, not ruling it out. Just saying that aliens are PROBABLY not trying to talk to us by fucking with stars' outputs

Ways to change the spectral qualities of a star:
-pass a prism in front of it
-pass a planet with a spectrally modulated atmosphere in front of it (fancy prism.)
-drop mass with a different spectrographic profile than hydrogen or helium into it
-ignite mass with the desired spectrographic profile with a probe in the photosphere
-like I said before, just send a laser beam with different spectral properties in the same direction as photons from the star are travelling
All of those things would be trivial for a 1K civilization. Does that mean it is aliens? No. But we can't rule it out just because the method seems exotic. It might be hugely practical. I mean, the only thing they can see about our system is the star too, right? If we wanted to send them a message, and knew nothing about whether they are looking for radio signals or anything, the one thing we know they can see about us is our star, so if it can be used to send a message, why not?
