Oh, did it say that the energy burst was packed with code?!

I can imagine a high tech device which behaves much like what we know as a 'LightHouse'
a beacon of radio energy, crammed with a densely packed 'code' (their version of HTTP) that sweeps around the sky just like the 'lighthouse' beam-of-light in the proposed analogy
only an advanced enough civilization would be able to detect the pulses of radio-waves packed with code
only an intelligent & advanced but distant civilization would seek to decipher the code in these short bursts
The last I'd heard, the EM Drive was still under investigation and the Chinese were testing it (or a version of it) in orbit.
NASA Eagleworks were still testing and there was a paper last November that seemed to ratify that the thrust effect was real.
The Chinese tests reported by the International Business Times report were later corroborated; at a press conference in Beijing on 10 December 2016 at the China Academy of Space Technology (CAST), Yue Chen, head of the communication satellite division at CAST, confirmed the agency is already testing an EmDrive in low-Earth orbit onboard an "experimental verification platform" believed to be the Tiangong-2 space station, and that it has been funding research in the area for the last five years. It stated that the current prototype generates only a few millinewtons of thrust, and that it will have to be scaled up to at least 100-1000 millinewtons;

Awesome find! There's no way we are the only intelligent life within such an unfathomably massive universe, the universe is perfect for life, just look at the ecosystem our planet alone has.
Unfortunately these signals were most likely sent millions of years ago and the thing that sent it most likely gone. Fascinating story though, S&F.

Good one HTTP lighthouse comes in mind....
And they do that for many mijlons of years ? I mean what is the change we detect a pulse during the 'sending time'.
Look I understand what you saying , basically they use tech that we use too just somewhat bigger. But the energy output equal to an entire sun output of a day unlikely ??? So what's the point.... another civilization hears a big beep. Can we communicate ? how much time takes it to communicate ? Why not going at sublight speed to an planet with methane output (one can see that with spectrometer) ? Takes less energy and leads to real communication. Timedilatation would make for a very fast trip in the reference frame of the alien astronauts....
Anyway exited as I am I still think it's just a glitch ...
If they are exploring space and are just guessing where other civilisations are, then it would make sense to just have a short transmission that is fired out in every likely direction. Between the time that it takes for the signal to reach the nearest star and a reply to return, they can explore others areas. It might take some time for the other civilisation to decode that simple pulse. Depending on the frequency, you could get a good few Megabits or Gigabits across.

Do you have any info you can post regarding a recently discovered Magnetar quake that this might be attributable to?
Magnetars are a particular type of neutron star that has an enourmous magnetic field.
On December 27, 2004 there was a large, short duration, gamma ray burst (GRB 041227) which came from the Saggitarian constellation.
The burst was phenomenally powerful at a magnitude of -29 and it was the brightest such event known, releasing an estimated 1.3 x 10^39 Joules of energy in about a tenth of a second (this is about the same energy our Sun would release in 100,000 years).
Of course, astronomers went nuts over it trying to gain an understanding of how something could be so powerful.
They identified that although the object at SGR 1806-20 was most likely physically small (about 20 km in diameter), it had an incredible magnetic field of 10^15 Gauss.
When such a condensed matter object compresses further, it fractures as it assumes the new new density - a star quake. It's like a supernova that blasts out energy instead of matter.
The source was about 50,000 light years away, but if it had only (only!) been 10 LY away, it would have ripped off the ozone layer and likely have sterilized the Earth!
Thank God for lots of space.
