It is interesting that the stars concerned are all sunlike stars which are consdered good candidates for habitable planets. It is also interesting that the modulations (the supposed signals) seem to resemble each other, even in stars many, many light years apart.
This could mean either that their civilisation is that much spread through the galaxy, or it could mean a federation of civilisations working together. Or, it could be signals being sent from many remote robots spread far and wide, acting as both a communications grid and a gigantic GPS for spacecraft.

I'm a little dubious that no red dwarf stars are involved, though; this seems to conform to our own preconceptions of habitable stars, rather than reflecting a wider set of possibilities. Red dwarf stars would be attractive prospects for civilisations that wanted to survive into the deep future of the universe. Perhaps they know something we don't.
Rimmer was too annoying for them.

An interstellar internet is a fascinating concept, but . . .

If you get a message from a Rigellian general asking for your banking information because he needs help getting 100 billion groodles off-planet, you should probably just delete it.

Perhaps we need to delineate between contact and detect, with contact being an intentional transmission towards us (even if not directly towards us, but an "is anyone out there/hey we exist" transmission like we sent from Arecibo) and detect being discovering non-intentional transmission such as finding chlorophyll in an planetary light spectrum.

Detecting life is not the same thing as making contact with intelligent life. There is probably lots of non-sentient life in the universe; that doesn't imply that there is anything out there to talk to.

Are aliens communicating with neutrino beams?
June 2, 2017 by Matt Williams, Universe Today

It is no easy thing to search for signs of intelligent life beyond our solar system. In addition to the incredible distances involved and the fact that we really only have indirect methods at our disposal, there is also the small problem of not knowing exactly what to look for. If intelligent life does exist beyond our solar system, would they even communicate as we do, using radio transmitters and similar forms of technology?

Such has been the preoccupation of groups like the Search for Extra Terrestrial Intelligence (SETI) Institute and, more recently, organizations like Messaging Extraterrestrial Intelligence (METI) International. A non-profit dedicated to communicating with extra-terrestrial intelligence (ETI), the organization recently suggested that looking for neutrinos and other exotic particles could help us find signals as well.

First, some clarification should be made as to what SETI and METI are all about it and what sets them apart. The term METI was coined by Russian scientist Alexander Zaitsev, who sought to draw a distinction between SETI and METI. As he explained in a 2006 paper on the subject:

"The science known as SETI deals with searching for messages from aliens. METI science deals with the creation of messages to aliens. Thus, SETI and METI proponents have quite different perspectives. SETI scientists are in a position to address only the local question "does Active SETI make sense?" In other words, would it be reasonable, for SETI success, to transmit with the object of attracting ETI's attention? In contrast to Active SETI, METI pursues not a local and lucrative impulse, but a more global and unselfish one – to overcome the Great Silence in the universe, bringing to our extraterrestrial neighbors the long-expected annunciation 'You are not alone!'" ...

I wish I knew more about this kind of thing, but even the popular articles tend to lose me--a layman--in jargon before long.

We’ve just seen 15 new mysterious cosmic radio bursts from space

By Leah Crane

One of the most mysterious objects in space just got even weirder. A group of researchers just found 15 new fast radio bursts, all from the only one of these objects that we’ve ever seen repeat.

Fast radio bursts (FRBs) are some of the universe’s strangest phenomena: powerful radio signals that flash from distant space for milliseconds and then disappear. They have been attributed to everything from black holes to extraterrestrial intelligence.

Because they’re so brief, and because radio telescopes can only watch a small area of the sky at a time, only about 2 dozen FRBs have ever been detected. Of those, only one has been observed to repeat: FRB 121102, which resides in a dwarf galaxy about 3 billion light years away from Earth.


Now, researchers with the Breakthrough Listen initiative, a $100 billion search for signs of intelligent life in the universe, have detected 15 more pulses from FRB 121102.

These aren't attempts at communication - who would expect to get an answer back grom a galaxy three billion light years away? But they might be the unintended consequence of very advanced technology. A distant civilisation three billion years ago might have found out how to crack the cosmogenesis problem, and created a new universe to live in. This is incidental radiation from the creation of a baby universe.

This idea was suggested by Lee Smolin in his 'Fecund Universes' theory - new universes can be born out of old ones, leading to a process of natural selection for universes.
https://en.wikipedia.org/wiki/Lee_Smolin#Cosmological_natural_selection
By tweaking the initial starting conditions, a sufficiently advanced civilisation might be able to create a universe that is more suitable for life than our own - and then go off and live in it.

One of the more unusual answers to the Fermi Paradox - sufficiently advanced civilisations create their own universes and don't bother with our, less-than-perfect, example.

A press release put out by the Breakthrough Listen organization, which funded and organized the project says; “Possible explanations for FRBs range from outbursts from rotating neutron stars with extremely strong magnetic fields, to more speculative ideas that they are directed energy sources used by extraterrestrial civilizations to power spacecraft.”

What SETI is putting out there worries me. We should be putting out loads of pictures of boobs and cats out there. Who doesn't like them? Those science geezers scare the shit out of me in not including a playful ambiguity in the commnication plan. While Sagan was great, I think there's also a role for Doddy in alien communications, missus.

I mean... let's look st the kitchen of a party. Who really wants to hang around with the nerds?

Why is an equation better than a great joke?

Equations are easier to translate since maths should be universal.

..Who really wants to hang around with the nerds?..

One could also ask who wants to be in a room full of people who think cats and boobs are suitable envoys of Earth life. Sounds like an average pub night.

'Ee Gladys, fine pair you have there; almost knocked mi pint over. I heard there are pictures of your pussy on their way to Jupiter'.

You'll be suggesting we transmit East Enders and videos of football matches next.

Well the Voyager plaques have a naked male and female, so we are trying with boobs. Don't know about cats though.

Utterly, utterly impossible budgets, New Scientist!! Shame on you

Article amended on 1 September 2017
We have corrected the budget of Breakthrough Listen
That's a thousand times better, thank-you!! Or as a British publication, might that even be a million times better?

In space, no-one can hear you scream about the casual errors lurking within popular science and it's associated media reporting.

Cue the revised data regarding the quantity of repeat FRBs from one unique constellation sector....."Well, we said 15...but...."

I have what I fear may be a valid technical question. Since this global array of radiotelescopes must somehow emulate NASA's DSN geotopical equipositioned acquisition sites (but, by definition, not in every sense of that requirement) how certain are the FRB project leads that this dataset outlier is not a aggregation artefact?

And dare I, as the arch-skeptic who doesn't even believe in the existence of all sceptics also enquire....how close was this discovery made, on timeline, relative to the end of this project's funding stream?? Hate me all you want, for saying this. I'm just absolutely looking forward to being told that this data was obtained during the project's first quartile of current budget funding, and not it's last....

Shout me down, world, for being a cynic...but, more importantly, tell me I'm wrong nb I merely query this financial information point based upon personal paranoid projection, I've not yet researched it. But when/if I do, I shall attempt to be more fiscally/chronlogically-accurate than the 10*^3 (or 10*^6) reporting error made by New Scientist.

It seems the West has abdicated its leadership ambitions in outer space as well:

What Happens If China Makes First Contact?
As America has turned away from searching for extraterrestrial intelligence, China has built the world’s largest radio dish for precisely that purpose.

Last January, the Chinese Academy of Sciences invited Liu Cixin, China’s preeminent science-fiction writer, to visit its new state-of-the-art radio dish in the country’s southwest. Almost twice as wide as the dish at America’s Arecibo Observatory, in the Puerto Rican jungle, the new Chinese dish is the largest in the world, if not the universe. Though it is sensitive enough to detect spy satellites even when they’re not broadcasting, its main uses will be scientific, including an unusual one: The dish is Earth’s first flagship observatory custom-built to listen for a message from an extraterrestrial intelligence. If such a sign comes down from the heavens during the next decade, China may well hear it first.

Well then they'll send messages in Chinese and the aliens won't be able to understand.

PEDANT ALERT!: It's actually the Pioneer plaques. Both Voyagers are carrying golden records with "The Sounds of Earth" recorded on them. We just have to hope that whoever finds them hasn't entirely trashed their record players in favour of CDs or MP3s.

The Voyagers contain photos too, though no nudism (a naked man and a pregnant lady, chosen for its "non-sexual" quality, was vetoed after outraged prudes complained about Pioneer). And their golden records come with record players and instructions. Not that it's remotely likely anyone will ever find them, it was a bit of a publicity push to drum up support for the project and justify the expense.
