I like the fact that astronomers from the US and China are working together on these kind of discoveries. One day we will have a radio receiver on the moon. That would be awesome.
@Preston412 I mean yeah the CCP is bad and has done a lot of human rights violations. It's an authoritarian state, what do you expect? But there's nothing wrong with collaborating with China on a scientific basis. International scientific collaborations should be the last thing you care about in this respect. I don't think astronomers are the ones running sweatshops in China.
It's astonishing how much ignorance and sheer stupidity shines among fellow amateur astronomers that never been to China, let alone know anything outside of junknews.
Great video as always! And a reminder, "It's never aliens until it's aliens." By the way, if you ever take video ideas from random commenters I and I bet a lot of viewers would love to hear about that Nancy Roman Space Telescope which AFAIK is NASA's next great observatory after Webb. Thanks so much for the videos and all you do!
You have such a striking way of delivering information. You lead us through the step by step process of falsification in such an elementary way, digging into many practical obstacles that these researchers have to manage. At some point, they run out of ideas or hit the limits of their instrument's capabilities and have to publish as a cry for help. "Global scientific community, please help me get rid of this line!"
Even if you could with certainty say that you have discovered an alien signal - what would it help? Could you then also already _interpret_ such a signal?
usually i get annoyed by "it's not aliens", as if it's the only reasonable assumption they can come up with, but your explanation was very helpful, i had no idea those radio telescopes gets thousands of signals very often (false positives) i always thoughts that SETI worked the other way around
Quiet interesting info! Thank you for explaining things in a clear, concise, and easy-to-follow manner, Mr. Ready. Always look forward to your videos!😊
The opposite of clickbait -- you say right in the title that this is probably not what we're all hoping for. Then the video itself is divided into chapters so we can easily navigate to the part we're interested in if we don't feel like watching it from beginning to end. More YT channels should be like this.
@selfworthy …. I agree. Most people are too concerned about their favorite celebrity or what the Kardashians are doing to give much of a hoot. To me, it would be a view changing event since I tend to think we are alone.
I recommend reading a sci fi called "The Three Body Problem". It's fiction but it shows the most plausible scenario about what would happen if we receive a signal. Little spoiler: it doesn't have a nice ending.
I went to Green Bank Observatory on Friday and I highly recommend it. Make sure you buy tickets before you go, they sell out fast. I learned a lot, like it was the GBT that discovered Sag A.
I hope you are making a video on the Webb's first images... Please also demosntrate the corresponding MIRI images of all the four images taken by webb.. Also please tell that which color represnets the most energetic (high frequency) short wavelength light and whichcolor represents the least energetic (low frequency) longer wavelength light in both NIRcam and MIRI images... I am only confused by the blue purple and green color in the MIRI images; there are no purple and green stars then why so much purple , blue and green color in MIRI images... Furthermore , Nasa recently released yellow orange and red colored NIRcam and MIRI images of Jupiter... Which are absolutely making no sense... Why they haven't used all the seven colors for the depiction of different wavelengths in the Jupiter image? Will we ever get the colored image of Jupiter? Please clear these misconceptions in your next video on Webb's first images.. One more question Will Webb give us answer to the question: Whether we live in an open universe or a closed universe?
1.14GHz with a bandwidth of only 1Hz is artificial. That’s a perfectly tuned RF signal. If it is interference can’t they just figure out if one of their pieces of equipment is operating at 1.14GHz and rule it in or out? Help me understand
"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.
The Thing is that sígnals most probabably are not attempts To comunicAte But residual activity not necesary trying to reach us… really nature behaviour of the electro magnetic spectrum is easaly distinguible
Loved the video! Concise and informative as always. So after all our work at radio silence on the hydrogen line we somehow made a telescope that can perfectly fool itself with a fake signal (from itself) right on the hydrogen line? With all the hallmarks were looking for? Also with respect to the habitable zone and liquid water, a huge caveat is that you also have to have a substantial atmosphere. Seems like no one ever mentions this. The moon is in the habitable zone and liquid water can't exist there because it has no atmosphere. Atmospheric density also plays a huge role with respect to distance from the star and liquid water. I know the habitable zone is just a ballpark but atmosphere is at least half the equation and is never mentioned.
I'm glad you liked the video :) And yes, point well taken that just because a planet is in the habitable zone, it doesn't mean it actually has water. An insufficient atmosphere would be a very good reason.
Wouldn't polar telescopes on the Moon be a better option? There's a bunch of craters located near the poles that are in permanent darkness and yet are mere meters away from almost permanent sunlight, the perfect source for powering any telescopes and other equipment within the crater. The deeper parts of these craters are also shielded from RF interference from Earth (and the Sun!), but again, a judiciously positioned radio antenna outside the crater walls would provide continued communications with Earth without requiring them to be bounced off a satellite.
I wonder how strong this signal was, just as a general point of reference. If it was an omnidirectional transmission from Kepler 438b, what's the order of magnitude of the transmitter power? Megawatts? Also, I wonder, would we even notice our own civilization in a mirrored SETI search? Doesn't seem likely, we just make a lot of relatively low power noise all over the spectrum. Nothing that'd make a big bright narrowband trace on an alien spectrograph, like the ones we're looking for.
They're supposed to broadcast outside of the frequency range reserved for astronomy but it's hard to completely avoid spilling into that range on occasion. So yeah, it'll probably get worse :(
Hello all i am in tenth grade confused that which enginnering field should i take please comment this this one to let me know and why........................ i am very serious about this .............. Thank you in advance and see my fav subj. is maths :)
You’ve got plenty of time to figure it out. You can change you major if you change your mind and that’s still years away. None of us can tell you what you should do. I’d think at this point you should just focus on mastering math and computer programming as well as you can.
I am interested in many things so I spend little time on a lot of interesting science facts. Therefore I appreciate this video for its high concentration of information in a very clear format. A short one but most probably a lot of work to produce all those fragments. As it is for the scientists to deal with over a million signals and then sifting out only 1 interesting subject.
0:49 “ Even if it does get published it’s by no means conclusive” you mean it is scientific. Science is never conclusive. Science is always self speculative.
Scientists can publish a "preprint" version of their paper while it is still undergoing peer review. Good reasons for doing this are for time-sensitive research (e.g. many of the papers about Covid-19 were preprinted to help inform and guide other teams in their efforts to understand the disease and how to combat it), and to help control the flow on information when word of more controversial or newsworthy research (like this one) leaks out leading to lots of ill-informed speculation. Of course, preprints can be used by more unscrupulous scientists who, for example, know their paper won't pass peer review, but want to make a splash anyway for less-than ethical purposes --- like promoting fake cures for Covid...
There seems to be a problem with explaining the waterfall signal from Kepler 238 as coming from the instrument based on matching polarization. That is -- you would not expect the signal from the instrument itself to be a waterfall signal - as you point out, you can get a waterfall from the Doppler effect of a moving satellite or airplane but not from a stationary component in the instrument. Also the fact that just the central detector registered that signal also tends to distinguish the instrument itself generating it, as all the detectors should have detected it. Is the polarization detection relatively new? If so I'd check if that was working correctly.
Perturbations from unstabilized sources like microwaves can drift in a similar fashion to this, and while it's improbable that it would drift in just the same way a Doppler shift would look like, it's not impossible. Also I said microwaves but don't actually expect them to be as narrow banded as this.
1420 to 1720 MHz. It spans the range of frequencies for hydrogen (H) and hydroxyl (HO), so the hypothesis was that since these two molecules combine to form water, and since it's also in a naturally quiet part of the radio spectrum, that might be a good range to broadcast in.
I has nothing to with drinking water. It's because water in the intersteller medium absorbs in that wavelength so it's handy for telescopes to look in that band since there's less noise.
why are you saying "relax"? no-one is freaking out about this. This is a SETI thing, we're looking for aliens. Here's a possible signal. let's talk about why it's probably not aliens, and what evidence would be needed for something to more likely be extraterrestrial- perfectly reasonable science communication. Please stop projecting
They're not going to rebuild Arecibo. If they reuse the site, it will be for a completely different radio telescope with far greater capabilities than the original. As for cost, nobody knows unless or until the new specs have been completely, and that depends on what the astronomers want and how much Congress is willing to put toward the project. Puerto Rico doesn't have anyone representing it in Congress, so it's going to be an uphill battle.
True, but unfortunately, it's not that unrealistic to believe there's none within reach of our telescopes. We could easily be the only technological civilization within a thousand light years of here.
@@EnglishMike They wouldn't be detected through telescopes, they'd be detected through radio signals. There could be civilisations out there right now like ours and there hasn't been enough time for those radio signals to travel to Earth.
@@666chapelofblood There is also the problem of inverse square law. Any signals to be picked up by our dishes would need to be VERY powerful. A civilization like ours 1000 ly away would be undetectable from here.
@@TheEvilmooseofdoom I suspect any transmitting civilization that wanted to be found would use more than one transmission. The first would be a powerful but basic (though unmistakable) "we are here" signal, telling use where to point our most sensitive instruments. The second would be data rich requiring much more sophisticated and sensitive receiving equipment, perhaps even beyond our current capabilities. You can bet that if we're pinged by the former, we'd be investing a massive amount of time energy and resources to detect the latter. Yes, we're talking about very powerful transmitters, but then what else is an advanced alien civilization to do if they're lonely and want something new to study?
The thing about the Chinese dish is this is the first time we heard from it since they built the thing and they only have it to one-up the US so it's not clear how well it works. Also, they rushed to publish the signal's detection before they even checked what it was.
@EMAN67:RP forum Dude, this is a matter of Chinese culture. People have often gone into deep debt to obtain prestige items and is by far the largest consumer of luxury goods. They lack the equipment to build capital ships but go to great lengths to build a carrier they don't need simply because the US has 11 of them. So YES, they'd totally build a dish just to one up the US. This can be confirmed by how the ONLY innovation in China's dish was it was a little bigger than the American one operational at the time, but was otherwise off the shelf tech. They built this dish even as new tech rendered it obsolete as these days there are algorithms that allow two synced up smaller dishes to act as one enormous dish.
This is the first YOU have heard of it. They've been doing and publishing from there for years. You need to see the world a little past the tip of your own nose otherwise you risk making a fool of yourself again.

Wouldn't polar telescopes on the Moon be a better option? There's a bunch of craters located near the poles that are in permanent darkness and yet are mere meters away from almost permanent sunlight, the perfect source for powering any telescopes and other equipment within the crater.

Actually no, because polar telescopes can't see anything out of the direction of the pole, and that's bad
Just put them on the far side, larger sky.
I wonder how strong this signal was, just as a general point of reference.
If it was an omnidirectional transmission from Kepler 438b, what's the order of magnitude of the transmitter power? Megawatts?

The thing about the Chinese dish is this is the first time we heard from it since they built the thing and they only have it to one-up the US so it's not clear how well it works.
Also, they rushed to publish the signal's detection before they even checked what it was.
@EMAN67:RP forum Dude, this is a matter of Chinese culture. People have often gone into deep debt to obtain prestige items and is by far the largest consumer of luxury goods. They lack the equipment to build capital ships but go to great lengths to build a carrier they don't need simply because the US has 11 of them. So YES, they'd totally build a dish just to one up the US. This can be confirmed by how the ONLY innovation in China's dish was it was a little bigger than the American one operational at the time, but was otherwise off the shelf tech. They built this dish even as new tech rendered it obsolete as these days there are algorithms that allow two synced up smaller dishes to act as one enormous dish.
Can't rule that out. Chinese want to engage in oneupmanship even at the cost of science. Winnie the Pooh gotta be "the leader"
@@nishitd Oh yeah? Chinese breakthrough in science? Disctatorship. CHinA bAd. F⚛️ck you.
This is the first YOU have heard of it. They've been doing and publishing from there for years. You need to see the world a little past the tip of your own nose otherwise you risk making a fool of yourself again.
