SETI Talks: Mysterious Radio Signals in the Milky Way

- At the end of 2021, a group of astronomers detected unusual signals from deep in the heart of the Milky Way. More recently, another group happened upon a celestial object releasing giant bursts of energy, unlike anything ever seen before. These mysterious signals, which seem natural, were discovered using recently built radio astronomy facilities, such as the Murchison Widefield Array telescope and the ASKAP radio telescope, both in Australia.
These objects are unique so far, and radio astronomers around the world are looking back in their data to see if there have been similar detections in other parts of the galaxy. Are these rare one-off events or a vast new population we never noticed before?
It’s still unclear what truly are, but it’s inevitable that within the next decade, with the arrival of the transcontinental Square Kilometer Array (SKA), more of them may be found and help astronomers to solve mysteries like their origin.
To discuss these discoveries, we invited two researchers: Tara Murphy, professor at the Institute for Astronomy at the University of Sydney, and Natasha Hurley-Walker, head of the extragalactic radio astronomy group at the Curtin University node of the International Centre for Radio Astronomy Research, both are involved in the recent publication of these mysterious and transient signals.
Both researchers will describe the instrument used for these remarkable discoveries, some hypotheses on the nature of those signals and discuss the golden future of radio astronomy. Of course, we will discuss whether we can reject an artificial origin for those signals. Are we sure that those are not simply advanced civilizations trying to communicate with us?
Franck Marchis, senior astronomer at the SETI Institute, moderated the discussion.

Reminds me of a saying; "The more questions you answer, the more questions you have."
Enjoyed this program, thank you.
The radio telescope that found the WOW signal also found mysterious signals they called 'bumps in the night' from the direction of the galactic plane. Perhaps the phenomenon is related.
Detailed yet easy to understand your explanation of radio astronomy. Intriguing and somewhat unnerving info. WOW. WOW.
Very good and fascinating presentation.. Good luck to Tara Murphy and her colleagues around the world. :-) Thanks SETI.
Excellent. SETI is really doing some great work. This program was so good i couldnt stop viewing. I was riveted. Fascinating. I even liked the Q and A, which i usually skip. Great presenters.
Thanks. That saves me an hour of wasted time
Have to comment again. Where ya guys been?? Love ya. GREAT info. Wispers… where ya been???
Jacksonville, FL USA , still listening for anything that comes our way.
good luck !
What a great talk! And thanks for the MOOC plug, I'm enrolled!
Nice video and beautiful presentations I hope to now the origin of this Rado signal comes from good luck 👍
It's nice how little intrusive is the Australian radio telescope.
A very beautiful work. In far future our descendants will probably say: " SETI research became a full-fledged branch of science in the 21st century."
So, a US military radar operator discovered a pulsar and US military satellites discovered gamma ray bursts. I wonder what discoveries they have yet to tell us about? 🙂
Yeah, they probably have some very interesting things. 😳
Ikr. Well, considering the US military used to even deny the existence of a perfectly obvious air force base for years... I don't hold out much hope them ever 'fessing up to anything real...
They'll keep it quiet for a while.
Correct. They have been communicating with an extraterrestrial intelligence since they first established contact in 2019. United Nations told them they want a 25 year roll out. We are in year 5. Science Filmmaker Professor Simon just posted about it 10 days ago

Excellent job!I learned somuch
Glad to hear it!
You have to be scientific with these things! The SKA mentioned, will give hopefully us a lot more latitude to search for potentially intelligent signals. I also tend to agree with the comment that any signal would, most likely, be distinct, from what we have seen so far. Either showing some form of compression in the way the signal modulates over the length of emission or otherwise being blatantly simplified, from alien mind to alien mind....;) Always good to see, Thanks guys!
You are quite right. Well.... may i be the one to sugest a kiss to the lower Option to my person
Went to a SETI presentation at Princeton University, talked about the physics & technology involved in the search for Intelligence.

The Space is very exiting in every Way ,there is so Munch to learn for all of u’s, i hope seti is the first to Discovery life outthere, that i Think Will be a guarenty for telling the thruth to u’s all
I wonder if SETI should also be pointing their microphones at the center of the earth to listen to what`s all going on down there?
Indeed, Tyler from Secureteam10 has some interesting videos about weird sounds coming from inside of earth
There us nothing going on down there despite what u may have read on the internet
@@aristocraticnietzschean-ma1023 Because the Earth's poles are about to reverse, but will come before, during or after the micro nova, which is about a 12,000 year cyclical event.
I watched a video many years ago about a signel coming from the center of the galaxy, between Scorpio and Sagittarius, known as the Golden Gate of the Gods. They made a statement that ancient people speak about something coming from there causing destruction on earth. I noticed they pointed their telescope to the Silver Gate of Man next, I wonder what made them think of doing that, Orio's club marks that spot, between Gemini and Taurus
Many mythological stories com e from those constellations around the center of our milky way galaxy
"bubble bubble bubble"... Hot.
@@ericf1135 Actually, we don't have ANY CLUE what's going on "down there". Any scientist who is even _partially_ honest will tell you that.
Any chance that the new JWST could be aimed at the location of where these signals are originating from to see if any detection of life might be found?
I was wondering how much collaboration there is among radio astronomers, optical astronomers and the various space telescopes. The JWST may provide a very interesting truthing mechanism for some of these anomalous signals.
JWST will most likely be directed at Trappist system first - and hopefully we get advised of the findings - I am also trying to get answers why some of the data is to be classified and to date to no avail
the published policy of the JWST team.
- all images and other observation data will be published.
- for images in the General Observer program (i.e. observation requests from astronomers) there will be a period of exclusive access, usually 6-12 months. These images will still be stored on MAST but during the exclusive access period, you need to log in to access them; access is limited to the requesting astronomer. After the exclusive access period everyone will have access to the images.@@joannadziaduch2138
Wisconsin loves you guys
Why’d the audio go out of phase at around 40:00, making me dizzy with my headphones =(
Bravo!

Thanks for your prescient views, Carl Sagan.
They will contact us when we are ready
Did you know Cosmic Radio Signals can be polarized at 91mhz (fm radio);
160mhz (vhf radio ); 610 MHz ( on channel 78 uhf-TV) by keying a CB
Microphone over a radio receiver set on these radio channels with your home equipment.
These are known cosmic radio sources from outer space, 25mhz natural
Source, 91 MHz unknown source from the Constellation Sagittarius , 160mhz
Unknown source, 440 kHz, 1440 MHz and many others from Annual Review
of Astrophysics and Astronomy 1966 editor Leo Goldberg.
Facts: A lot of the static snow that you receive is your non-cable
Uhf TV; is cosmic radio signals......many elements naturally emit
radio pulses where excited; You can polarize these signals with CB radio
Microphone by keying the transmitting CB microphone over the speaker of a
receiving radio set at 91 mhz..(91fm)..160 MHz..(160 vhf radio)..and
transmit the spacey sound you hear to a receiving TV set at channel
78 UHF tv.....then you will see a ATT type of symbol..and see the
oscillations and fluctuations of the cosmic radio signal that has
been just polarized and hear strange 1960s Star Trek spacey sounds, ( I think
scientist playing around with 195s electronic equipment radio and TV made
some odd findings, like the ATT symbol ( world with stripes ) the CBS electron
gun inspired the 1950s CBS eye logo, and those 1960 Star Trek sound
effects...the odds are in our favor.we are receiving artificially generated radio
Signals...I think 91 MHz FM radio and 160 MHz VHF radio is artificially
generated...remember the old national weather radio station was at 162 MHz
VHF radio.
WOW signal
In a 1959 paper, Cornell University physicists Philip Morrison and Giuseppe Cocconi had speculated that any extraterrestrial civilization attempting to communicate via radio signals might do so using a frequency of 1420 megahertz (21-centimeter spectral line), which is naturally emitted by hydrogen, the most common element in the universe and therefore likely familiar to all technologically advanced civilizations.[4]
In 1973, after completing an extensive survey of extragalactic radio sources, Ohio State University assigned the now-defunct Ohio State University Radio Observatory (nicknamed "Big Ear") to the scientific search for extraterrestrial intelligence (SETI), in the longest-running program of this kind in history.[5] The radio telescope was located near the Perkins Observatory on the campus of Ohio Wesleyan University in Delaware, Ohio.[6][7]
By 1977, Ehman was working at the SETI project as a volunteer; his job involved analyzing by hand large amounts of data processed by an IBM 1130 computer and recorded on line printer paper. While perusing data collected on August 15 at 22:16 EDT (02:16 UTC), he spotted a series of values of signal intensity and frequency that left him and his colleagues astonished.[4] The event was later documented in technical detail by the observatory's director.[8]

Hello from Xenia, Ohio, originally from Marcus Hook, Pennsylvania
Hi there from Jeff in Brisbane Australia
I would be looking for a reply signal no more than 9 light minutes away.
Dallas Texas thank you.
cheers from Canada
Please try to answer if seti RECEVD a signal frome 25april 2022 until now I need yor answers for something in this repeating pulsar your answers will be getting approved for the string signal UAPs please try to answer. I like 👍 your presentation thanks
How we know the ability of energy they can produce. And how we judge the ability of something we don’t know about.
I wonder what the standard deviation of narrow band against periodicity constitiutes proof of aliens?
Here is what they say : "Watch 581D" " Last of 5" - thats what Wow signals says, and I never heard of 581D so I couldnt have made this up. Thats what the 2nd and 3rd WOW messages say. I wont say the first one. There were 3 not 1, wasnt there? Maybe not at same time. They ciphered them all, but what they did, was use a variety of earth languages, sometimes, right in the middle of the cipher. This is what they say in English. All the public has heard of was the first one.
hi Simon, I'm from India
Simon, at beginning: Your camera is too close. But on the plus side, your lighting is nice and diffuse, keeping your face from being too shiny-a common mistake.
I believe we are not alone in the universe. Look up to the stars!
Regarding SETI: Those antennaes they use must be very sensitive to even the faintest of signals, that given; I wonder if the continually broadcast streams of the signals beaming out from our civilization here on Earth may be reflected off of distant objects back to the SETI antennaes? They could be reflected from multiple celestial objects while they themselves are moving in clockwork order in relation to each other and thus create faint signals apparently unique and rhythmic but also unidentifiable as our own due to the cacaphony we project, and the distortion from having traveled a vast distance through space and back again. The pattern of variance could seem mathematic and thus intelligent to us even though it is the variance of the reflecting objects to each other. Even only one of our millions of sigals from Earth would be reflected from many celestial objects with untold timeline/varying distances of travel back to us even though originally they all eminated from our world at the same instant.
Anyone have any thoughts on that? I'm sure they must have already thought of that but I've not seen any info on this possibility. This could really confound our search for extra-celestial life.
Also close to home,to what extent do all our satellites effect the gathering of distant radio signals, especially now with the orbital pollution of the Starlink grid.
There is a system of sensors according the the military magnetic anomalies amd wind direction speed app's
An image 130 million light years away you say. Mmmm Hmmmm. I see, go on...
The originating f uab is from our earth location of the signals from earh yhen to sky and back to earth you can look after in thrs waymight you will gound it tray and tray?
How can they say aliens have not been found. When I myself have stories from 2people I know personally who do not lie and myself. I don’t lie

I guess there are many possibilities. A new star being born. An old star dying. However what happens when a large body like a planet collides with a star? In new solar system it's likely one or more planets will dive into their sun. Then there interstellar objects.

hope my contributions are being used astutely.
NB.not a lot. tbh but their is a lot of talk. .
What's it saying tho?
Seems that the goal is always to rule out natural events. How far is the source of anomalous signal? If it is too far, is it far from the past?
Now I need to know how circularly polarised radio waves can be generated by an astronomical system. A new obsession, just in time to take over from FRBs as their physics becomes settled...
Can’t understand them

They just drone on about guff and don't mention space creatures at all 👈😕
I wouldn't discard all wideband signals as non-interesting. We have also come to usage of wideband signals such at bluetooth (random frequency hopping) and LTE (multiple subcarriers each having their own data streams). Or course these signals are dictated by properties of the medium where they are used, such as multiple users accessing same channel or multi-path propagation. Still, who knows what reasons might aliens have to use wideband signals?
If aliens think big, they may use wide bandwidths.

No entiendo lol!
😂❤❤❤❤❤❤❤
Well i can see qite a big hole in this theory
So, in 10 years we will see when Dielectric energy becomes its field of Dielectric voidence field/Magnetism? These transverse waves create nodes that EM waves/Light propagate on.
Cool!

Low level signal capture is fascinating.
Too bad 154Mhz is a widely used commercial band in the states.
No possibility of detecting anything useful at that frequency, might as well tune into 10 Mhz WWV for all the good it will do.
Its been known for a few decades, that maximizing channel capacity over a broadband channel is...in the limit... indistinguishable from white noise. We may not be able to eavesdrop on signals of alien races if they are even a few decades more advanced than our own...if they didnt want it. It may be possible to eavesdrop on industrial civilizations at our level (100-200 year time window) but since our most powerful radiotelescopes could not easily pick up an alien version of i luv lucy even from our nearest star...alpha centauri...i think the jury is still out whether we yet have the technology to rule out alien civilizations. Unless we get lucky with a talkative sentience..we would need massive radiotelescopes on the moons far side to eavesdrop on alien signals in our galaxy and exclude the probably likely possibility of other civilizations. Such knowledge...even from civilizations roughly at our level...could be a huge boon to technological and political growth..as they would have developed technologies different than our own and just even knowing they are possible would create incentive and funding to rediscover them. How to avoid nuclear and environmental catastrophe would also be very useful knowledge.

Don't you think it's odd that you guys found a radio signal exactly where Paul Lafayette he said there was one, he learned it through ancient mythology. I wonder if that's signal is what makes our son micro Nova every 12,000 years oh, something that I have come across reading symbolism in mythology. Last give credit where it belong to Paul Lafayette for pointing you folks in the right place to look
Lolololololol... "Ancient Mythology"?
Hahahahahahahahahahahahaha!!!!
I laugh, but it's actually pretty scary that folks like you live among us and do things like drive cars and vote for our leaders.
@@davecarsley8773 Why is it such a monstrously ridiculous idea we were contacted when we were a completely technologically ignorant species and the contacts gave us information which we recorded the only way we knew how, through mythology and story telling? Where they came from would be one of the most basic ideas to communicate, point at something in the sky, or draw a star map and point to it.
Lol. You are looking too far away. They are here,
I do not get a sense that any real science is going on...
Great talks, even better to see not one but two women presenting! Thank you
What`s the difference whether a man speaks or a woman speaks? We are all created equal
@@spekblue6027 I bet a man can't give birth a child, but the woman can't give birth without that that comes from a man. Not so much equal but each has their purpose. Seems man create with his hands objects to kill things that the woman creates with her body
Why is it "better" to see two _women_ presenting?? Don't you want to be listening to the absolute smartest people on the subject, whether they're male or female???
If the most knowledgeable people on a subject end up being female, that's cool! But if they end up being male, why is that "worse" (or at least "not better") to you???
Are you truly SO shallow, superficial, and closed-minded that the most important thing to you is what genitals a given speaker has in between their legs, not the knowledge that speaker can present to you?
If the former is more important to you than the latter, I'm really sorry to say this, but you're making our world much, much, *MUCH* dumber.
"Equality", right? lol.
@@spekblue6027 What's the difference? Genitals... That's all.
Sadly, some _extremely_ shallow and anti-intellectual people care more about _genitals_ in 2022 than the intellect of the person speaking, and what they might actually learn from them.
Let that sink in... *Some people in 2022 actually care more about **_genitalia_** than they care about **_knowledge_** when listening to SCIENTISTS speak!*
The future is looking very bleak.
@@chuck1135 Historically society has assigned roles based on gender. It has meant that both men and women have been pushed into or kept out of roles not depending on passion or ability but according to gender. It's quite heartening to see women scientists as this suggests some of these damaging, restrictive ways of ordering society are becoming less prevalent. Does that help with your confusion?
Please don't cloud the issue with facts. Mick West has already debunked anything you might say.
Mick west could “debunk” humans existing… most of his “debunks” are just dreaming up some way the information he’s analyzing could be something other than what it clearly suggests, if it’s not that it’s arguments from ignorance, where he shows something isn’t 100% clearly and unequivocally proven therefore we should just accept his conclusion that it’s faked or that the conclusions reached are false.

SETI has been around a long time why is it that we have not been able to pick up other planets like earth. I would assume that we are the only form of life in space. How do we know that the signals from space aren't picking up the junk that is around our earth?
It's called being "intelligent" and using "science". We eliminate all possibilities of terrestrial interference before we declare anything to be extraterrestrial.
By the way, SETI isn't looking for "planets like earth".... at all. They're looking for radio signals-- that's it.
Honestly, it's extremely closed-minded to assume that any other intelligent life in the universe MUST use the *exact* same methods of communication that _we_ use or they simply don't exist.
We've been searching for like 45 years. Do you understand the speed of light? Do you have any clue how big the universe actually is??? Lol
We are all alone in the universe.

We know the Aliens exist. Why do you continue to refuse to take the L?
We are all alone in the universe. What STTI is doing is a waste of time and efforts.
You again? Maybe you're the one that's alone... ha ha just kidding but I do disagree
@@IKimbers Search for trashy, terrestrial intelligence? A waste of time? No way! Just turn on your TV set or a radio.
