I'm the lead researcher on this study and I can honestly say: this is a great summary of our work! Thanks for producing this lovely video. And to viewers: we are working on figuring out what these things are! Literally, watch this space 😁

Reminds me of that "mysterious radio signal" researchers were trying to decipher for 17 years that turned out to be their microwave

[SirBoden]

Sorry, I’ll get around to changing the battery. I know it’s annoying to hear that beep every 22 minutes.

[MrTomLegit]

My fun sci-fi idea off of this is a civilization that has figured out how to create these extremely stable pulsars. They use them for timekeeping/navigation. They have to come by every so often to top it up like a generator or tend it like an actual lighthouse.

The Dyson Sphere runs an ejection routine every 22 minutes. There are variations between each ejection due to the quantity of material being ejected.

Last time something major happened every 22 minutes in space, I was caught in a time loop searching for the Eye of the Universe.

It's a "car alarm" that got false-triggered on one of the aliens' space ship while it's parked somewhere. The owner never bothered to shut it off and now it's just been "blaring away" non-stop, bothering the entire "neighborhood" for decades.

[Evdog]

It makes me so happy that there are people smart enough on this planet to know this stuff. Gives me hope for humanity.

00:07 Astronomers have discovered a mysterious radio signal arriving every 22 minutes for 35 years.
02:08 The radio signal source has maintained a consistent rotation period over the past 35 years.
04:10 Neutron stars are incredibly dense and have a strong magnetic field.
06:15 The pulses of light emitted by pulsars are detected as a result of a pair production cascade.
08:07 The signal is detected even though it doesn't match the properties of a pulsar in the death valley.
10:05 Astronomers have detected a radio signal from a neutron star every 1318 seconds for 35 years
12:01 The identity of the signal remains a mystery after 35 years
13:47 The source of the 22-minute signal remains a mystery despite various theories.

I write hard sci fi and have come such a long way in my education on astromony since leaving any formal education on it, but this mystery is just so grand and beautiful that i feel any guess i could give would only bismirch the topic. Hats off to the researchers working on this ❤

[cteal]

It is when the signal stops that we should be worried.

[draigon]

Varying by 6 minutes is a LOT
But not over 35 years. That’s basically PERFECT

[carpemkarzi]

Another great video. The more I think about it the more I realize (I know I’m late to the party) that anything dealing with space is all some form of archeology. Always peering into the past trying to figure out what happened. It’s lovely

[TazyBaby]

You definitely should’ve made this video 22 minutes long

[comedyatitsworst]

aw, gosh darn it! those darn hearthians - they've activated the ash twin project!

[KdetJim]

Could it be something akin to gyroscopic precession: the pulsar is spinning at a speed that makes sense, but is precessing once every 22 minutes? The earth spins around the geographic north/south poles, but those poles precess such that the Polaris will eventually no longer be the North Star. That might also explain the variations within the 6 minute signal windows: every 22 minutes we get a glimpse into the chaos caused by its rotational motion, but then it processes away from us.

[mcwolfbeast]

Wouldn't it be possible that the pulsar is, in fact, spinning much faster but on multiple axes, resulting in this pattern? 3-dimensional rotations can give rise to some pretty complex, slowly-repeating patterns from a fixed observer PoV, and since we only have a tiny window of observation, I think it's likely that the 22-minute interval is just one of the secondary rotational axes, while we don't actively see the primary (fast) axis of rotation.

[daikucoffee]

The signal comes from the hot pockets in the cafeteria microwave.

Superb! So refreshing- so many other science content is full of meandering, rambling junk and B-roll graphics that have nothing to do with a topic, that I dreaded watching any science content. You’ve restored my faith! I’m subscribing.

[frankenoise]

That would really be a shame if someone outside our Solar System was trying to talk to us but we couldn't hear them.😔
