Something in space has been lighting up every 20 minutes since 1988

On Wednesday, researchers announced the discovery of a new astronomical enigma. The new object, GPM J1839–10 [...] takes 22 minutes between pulses. [...] The list of known objects that can produce this sort of behavior is short and consists of precisely zero items. John Timmer writes 900 words for Ars Technica.

Rare instances in lonely astrometrics.
"This is called "recycling" because it returns the neutron star to a quickly-spinning state. Finally, the second star also explodes in a supernova, producing another neutron star. If this second explosion also fails to disrupt the binary, a double neutron star binary is formed. Otherwise, the spun-up neutron star is left with no companion and becomes a "disrupted recycled pulsar", spinning between a few and 50 times per second.[39]

Somebody or something is goofing on us.
When I was in college many many pulses ago, my roommate and I were bored and decided to see what would happen if we dropped a lacrosse ball (loud thud) on the floor (cement with tile over it) exactly every 5 minutes. We wanted to see if the guy downstairs from us noticed. It took about 45 minutes (10 drops) for someone to come upstairs and bang on our door screaming to stop it. I bravely opened the door. He was not happy but did notice every 5 minutes about 5 or 6 drops in. Turned out that that dorm mate was my housemate 3 years later.
So maybe someone or something is bored and seeing if we notice.

Follow-on observations showed that the object repeated pretty regularly, with a periodicity of about 1,320 seconds (more commonly known as 22 minutes).This Pulsar Has 22 Minutes. (If you are baffled by this reference, you are probably not Canadian.)

It's in the Galactic plane, so not visible. Apparently also not detectable outside the RF spectrum. Which is reported by Ars as though that means it only emits RF. But what if there's stuff coming out all the way up to X rays that are getting absorbed by the galactic crud background?
I'm no expert but I'd think that would open up some not-ridiculous explanations.

Seems like this thread is in desperate need of a tl/dr, so:
It is not 22 minutes on the dot. That's the average, but there's a wide error bar on that (close to 7 minutes). Sometimes, such a period even passes entirely with no bursts.
Also, that's not the only highly variable thing about it: The length of any given burst can vary (30 seconds to 5 minutes). The intensity of the main burst can vary. And I say "main" burst because there can be "lots of sub-bursts" during the activity.
To my mind, that all says "Don't get your hopes up; it's not going to be aliens", but simultaneously screams "OMG IT'S TOTALLY DEFINITELY ALIENS". I would very much like there to be fully dedicated continuous monitoring of it, so that we can look for any potential patterns (which, I imagine, would be of interest even if it's not aliens). Unfortunately, as the article says, "that involves a major commitment of hardware"... and they mean that about a much lesser goal (i.e. not continuous monitoring).

If it were aliens, how much power would they have to dedicate to this? Like, are we talking a nuke every 20 minutes, or are we talking magnitudes more power than that?

“If it were aliens, how much power would they have to dedicate to this? Like, are we talking a nuke every 20 minutes, or are we talking magnitudes more power than that?”
It's many more orders of magnitude. So many more, that your unit of "nuke" is meaningless. A typical solar flare, which itself is pretty much zero energy compared to this source, is equivalent to about 24 million fusion bombs (each of which is equal to about a thousand of the Hiroshima bombs). If it's aliens we probably have nothing to say to each other and, for us, that's almost certainly for the best. Personally, I'd fly away, not toward, any evidence of astroengineering.†
It's really tempting for me to speculate about what this might be and I can think of several very handwavy explanations which are all probably laughably wrongheaded. But my first thought is that our observation of this source (not the source itself) is being mediated by something else. But maybe the source itself is some complex process involving multiple bodies.
My intuition tells me — perhaps falsely, because at best I'm an astro fanboy — that at these extreme levels of energy, irregularity is usually short-lived so the more plausible explanations suffer from ignoring the implausibility of us happening to be looking during the transient (in astronomical time) irregularity. But of course that would explain why we don't see more of these. This is what happens when you only have one example of something. Every explanation is very weak.
† That was an outrageous lie. I'd fly toward it as fast as I could get there because I have a demonstrated tendency toward intense curiosity untempered by any sense of self-preservation. At the age of four, I wandered off into the mountains from a campground and was lost for hours and I've not developed better sense in the subsequent five decades.

The article just feels like weak manufactured drama to me. So what if it's nothing experts have seen before? Many unusual astronomical phenomena start out with baffled head-scratching and slowly work toward an explanation. Some kind of irregular rotating dust cloud with a strong energetic source behind it? A new kind of pulsar who structure allows slower, irregular rotation? At this point who knows. Collect more data, model and test, repeat. That's science.
In any case, not aliens.

Scientific mysteries should be newsworthy, even if only on a slow news day. The article doesn’t make grandiose claims, or even mention aliens, it just reports on a scientific curiosity, explaining why it’s interesting, and how we might make progress on coming up with a solution.
