So happy for Dr Kipping and his team. Hopefully they find what they're looking for.
Not until they look at the electric universe lol
That guy is so pretentious its unreal
I wanna make a “that's no moon” joke bit I can't think of one so just imagine that I came up with a really good one.
I really liked his early stuff but the way he speaks is kind of getting to me a bit. He speaks slow amd then the next half of the sentence is super speed.
I absolutely love red giant simulations.
It’s so cool how they’re basically big puffy clouds that are almost blowing themselves apart. I wish we had similar simulations of other extreme kinds of stars.
"SIMULATION" is the operative word... IT'S NOT REAL... and can't be proven... 🤔
These stars are so unstable that they are always on the verge of blowing up, but the sheer mass of these behemoths prevent that from happening. A star of lesser mass behaving in this way wouldn't be long for the universe. The boiling action of Belelgeuce is probably normal for a red supergiant of that class. Imagine the radiation from that thing! It would probably cook any probe that got closer than a few thousand AU's.
@@Lennis01 imagine of one of those stellar "boils" popped. And spewed a bunch of plasmid matter off, like a blisteringly hot cosmic splash.
@@davecrupel2817I can imagine it, which is why I'm glad that star is 600 light years away from us.
@@Lennis01 YUP lmao same here!
One of the reasons why a lot of scientists DON'T think Betelgeuse is ready to blow soon is the fact that while the visible light went through a couple of really dramatic changes, the infrared light signature changed almost not at all. This is how they eventually determined that most of the light curve we all saw was due to dust blocking the star's light, and not anything catastrophic going on inside. =)
Its a 2 stroke and it does that
There aren't any "scientists" that think or don't think it will blow "soon" . Or you misspelled "journalists" . And dust blocking the light of a supergiant star... Supergiant cloud of dust in the vicinity of a very old - already cleaned star system.. "tabloid journalists" said so so it's science!
Scientist theorise that taking into consideration the age and how bloated is this star, it will /have "blown" in an astronomically short span of time (span of thousands of years) . And they don't think the dimming was because of dust but because of its bloated irregular state .
Years ago, I saw giant stars modeled as these boiling bubbly things, but every time I tried to look up more information on it, I came up empty handed. Stars are pretty much always represented as near-perfect spheres, even though we now know they aren't like that.
The models show that a star can't really explode as a supernova without this boiling bubbling process happening first. I also note the dust that obscured Betelgeuse a few years ago was actually made of Silicon Oxide dust. These are the last elements fused before iron is fused and the supernova happens. The Silicon fusing phase is only supposed to last one day. But for Silicon Oxide to be blown off the star in such large quantity, a small section of the core had to reach the last fusion stages at which time, that region became so hot compared the average temperature in the star, that it got blown out and literally outside of the gravity well to form dust in space. I mean, the Silicon Oxide dust cloud more-or-less proves that the boiling bubbling process is actually happening already on Betelgeuse.
the sun's surface looks just like that, except the bubble/radius scale is much smaller
@@paulwilson6511And if core fusion products made their way to the surface, then fresh, un-fused star matter from nearer the surface must have made its way down to replace it.
This is just how convection works.
This must be what is fueling Betelgeuse now. I'm curious if end-stage giant star modeling includes this level of convective burn-up?
@@NullHand I'm aware of small star models that are fully convective, I'm not aware of any where the model would include what's essentially percolation. Sounds like a good idea to model, just to see if it works and matches observations better.
I do recall some modest overturn modeling, but nothing on a scale consistent with observed behavior here.
This may be why they twinkle
Great video and congrats to Dr. Kipping for well deserved JWST time!!!!
J-WASTED time yes
I love how you can see betelgeuse reflected in your eyes in the thumbnail. Nice touch.
Its a 2 stroke star! the Arcticat 858 snowmobile is a small copy of beatleguess
I am so happy for Cool Worlds too, exciting to hear when their results come in.....thanks Mr Cain. So good.
Life on Earth emerged without oxygen, and when cyanobacteria began to produce it, they caused a mass extinction. Low oxygen isn't necessarily a bad thing for primitive life on Europa, but it might make multicellular life difficult.
Kind of true.
Can't have water without oxygen.
@@XtreeM_FaiL I think this is about diatomic oxygen. Like the kind found in air
@@basilcurrie8138 Documentaries have mentioned the cyanobacteria oxygen most likely turned the iron rich earth above the water line into rust rich land.
Kinda how Mars looks today
@@RectalRooterAre we wondering if Martian oxygen cycle bacteria ever evolved? If not, who made the D&M pyramid? 😂
@@user-gv4cx7vz8t I will claim the Zentradi till the day I die.
Man we gotta get Kipping back on after his data gets sorted!!!
I'm really happy for David Kipping. I've been watching his UA-cam channel Cool Worlds for a couple years now and he's done an amazing job at explaining what a big deal it will be to finally detect exomoons. When the first exoplanets were discovered in the 90s it opened the door to an entire new branch of astronomy, and now we're in a golden age of exoplanet hunting, so exomoons could be that next big breakthrough. I really hope he is able to confirm at LEAST one exomoon with JWST and gets a Nobel prize fore doing so. He's earned it.
That 2 stroke star needs to be rebuilt at a alien machine shop as its got worn crankshaft bearings and once thats done she will run fine!
Omg, that Space Telescope Live site rules. Reminds me of DSN Now, where you can see what the Deep Space Network is talking too.
I binged watched a dozen older episodes and have to give you an ATTA boy! Your content gets better and be
Hah, I'm glad their better now. I couldn't bring myself to watch them.
@@frasercainSpelling still needs a little work here lol. 😄
@@user-gv4cx7vz8t Nothing wrong with the spelling, it's the grammar.
@@TreeOnAHill For me, choosing the wrong homophone is a spelling error. I know how to use each one correctly, until I mistype them.
@@frasercainAmazing, the comment censorship on this page. The industrial-scientific term 'tooling' is forbidden.
The LIFE telescope derserves an award for that acronym.
Betelgeuse is a turbo 2 stroke star and is banned by the intergalactic EPA! It burns about 13500 gallons of 2 stroke oil a day!
If blackholes have interacting electromagnetic fields, then you may have something that bridges that Final Parsec Problem area. Even them both emitting Hawking radition may have something to do with it, if the mechanism proposed with that for expanding spacetime could end up interacting in a weird way... 2 things emitting things that are trying to spread out...
I"m delighted to have found this channel!! Priceless.
That real time tracking for webb and hubble is AMAZING. I'm absolutely going to observe the same thing at the same time whenever the opportunity strikes 😂 My 10" dob is no match lol
Same, it's just fun to know that you're looking in the same direction as the most expensive telescope (not) in this world.
Thank you for all you do , Fraser! I appreciate you very much.
Its a 2 stroke star and needs a 2 stroke tuner!
Interesting theory about Betelgeuse. The pulsations observed, Betelgeuse... another sign that the star is entering the final stages before the supernova explosion and can no longer effectively counteract the force of gravity. Combining all these observations, we can deduce with reasonable certainty that Betelgeuse is now in a very advanced pre-supernova stage. The extreme surface turbulence, together with the pulsations are the preludes to the final gravitational collapse of the depleted core and the subsequent supernova explosion. It would be interesting--I say, interesting--to visualize on a graph the number of neutrinos released by Betelgeuse to have a greater comparison on internal conditions. Should I venture from the latest data? Ten years at most, but it could happen tomorrow for all we know. Anyway, fantastic these episodes, love to see.
Thank you Fraser your videos are so informative and interesting :)
I love your channel! Definitely one of my favorites! Going to check out your interview with Kipping (Cool Worlds is an awesome channel too!).
Saw your interview with Dr Kipping and so stoked to hear that the Cool Worlds team got the telescope time👍
Back when gravitational waves from merging black holes were discovered, I read that huge amounts of mass are converted to energy in the making of those waves. Why wouldn't the weaker gravitational waves created by the black holes play a role during the final parsec in bleeding off orbital velocity?
Christ that thing is boiling ANGRILY
once I heard a astrophysics professor saying that red giants are like angry clouds, really hot and fast clouds
Someone left the stove on for too long.
It wants to blow up, but it can't. The star's mass is too great. Belelgeuse is in a perpetual cycle of explosion and collapse. It's hard to say which state will win out in the end.
@@Lennis01 she's just like my mental state fr
Powerband kicking in on that 2 stroke star!
It make sense.
If a star is unstable, such as when its in such a critically giant stage of its life, i dont think you can expect it to fuse evenly. Or to inflate and deflate evenly.
It makes sense that that instability would show itself in the form of such uneven misshapings like that. Like a boiling pot of water.
another awesome video. thank you fraser.
Thank you Frasier for the update
Mind-blowing content. per usual
cheers from Toronto thanks Fraser.
Definitely looking forward to marcus and scott coming on after starship launch.
Me Too
Very unusually I had Peritonitis at aged 2 years old. To save you from looking this up it's when your appendix explodes, and causes massive blood poisoning.
I was very lucky to survive this incident.
The good news is that if I ever become an astronaut I'll never get appendicitis, mine has been removed..
I believe all astronaut appendixes used to be removed. Not sure currently.
I forgot to mention that the doctors literally flushed me out with fresh blood and Penicillin.Which is why that I'm allergic to Penicillin. If I have it again I'll be dead :(
At least I'm still alive so thank goodness for medical science.
I've managed to get get to the ripe old age of 70 so I guess that I'll be kicking the bucket before long.
Why am I just now finding this channel. I nerd pretty hard, glad I finally got here.
Yes, excited for Dr. Kipping too.
Yayyy one of my fav Space fellas Dr. Kipping !! I saw his vid on him feeling down about being denied earlier and his pursuit of exomoons so this is super cool.
I'll try and follow up with him.
The Europa thing may be good news for life, considering the only instance of abiogenesis known to have happened likely did so without oxygen (on very early Earth). Compare Nick Lane's sentiment that oxygen is so reactive that it likely prevents the chemical mechanisms of abiogenesis, binding to hydrogen and carbon before they can form hydrocarbons (in the absence of highly evolved protein machinery).
nice work. first time here, nice to listen. thx.
thanks very much fc and for the podcast too. Night night🌙
4:45 really interesting seeing how much faster JWST missions are compared to HST; at least from a quick glance at the website. Explained by the size of the telescope.
wow..That Beetlejuice stuff is awesome.
Go, Kipling, go! Tadadada.... Exomoons here we come!
Fortunately, Betelgeuse's 650 light years away from our home planet Earth.
Maybe it blew up 649 years and 364 days ago, our time?
@@neilsmith9398 Nope, I don't think so!
@@neilsmith9398 I wish! But there could be as much as 100,000 years left on Betelgeuse's clock. One day that will be the case though. If there's still a scientific species still left on earth and they still have neutrino detectors like DUNE in Sanford or Super-Kamiokande in Japan they will have a 12 hour warning so they can watch it happen, as it happened, 649 years ago. 🤞fingers crossed that it happens in our lifetime though.
@@ameliadiaz8040I mean the whole point everyone is making is the light was boiling 650 years ago. So it could go off at any moment
@@ObamanableSnowman I'm pretty sure the star would show some signs before going supernova.
When gathering your space friends, it would be great to see Stage-Zero Zack (CSI Starbase) in conversation with you on the channel....
Amazing the possibility to follow live the great telescopes observations !!
Congratulations to Dr Kipping and team!
I'm happy for Kipping and exomoon search too 🎉🎉
Hey Frasier. I'm a fan of the site. In your Biggest Black Hole segment you answered your own question "How do you get a super massive black hole?," with "Only through the merger of less massive black holes." And you said it with conviction. It's your word "only" that raises suspicion. I have two words in response, "Direct Collapse." And perhaps five more given the speed of the refinement of our knowledge in this renaissance of cosmology..., "as far as we know." The Eddington limit has been shown to not be a universal truth or wholly capable of explaining whether supermassive black holes were formed in an instant at expulsion, or began forming or formed fully invitro causing the spew of the expulsion of this expanding universe, or whether Super massive black holes collapsed at speeds exceeding the limiter of the Eddington equation - the speed with which accretion of matter forms enough radiant energy necessary to repel known incoming material.
Your coverage of the most massive black holes discovered so far and that they are repelling all material around them, and are still merging, despite our math, is a great segment. It raises for consideration the very interesting question of whether the big bang was a black whole maturing - casting it's black hole seeds out with a bunch of food so that all the little black holes can grow, consuming matter to the point of maturity, which, when mature, gives rise to those bursting and expelling all it has consumed, like it's mother/father before it. What would trigger a black hole to reverse it's physics and spew forth a glob of universe seeds, to make more seeds, to make more? A flashpoint amount of matter? Time? Processes? Are universes a recurring resonance of energy perpetuating like life on Earth does? Could this rare merger of black holes cause their result to reach the critical maturation point so that they explode in a creating a universe kind of way? Or is this just a little black hole heavy petting with some more "merging" still to come? The growing rate of universal expansion would be a very useful element for a black hole universal seed scenario to work. Separate the seeds so there is space between them for the other universes to come. Not all seeds would mature. Would their remnants be detectible between the universes? Hard to get a signal back in time.
Many thanks for all the effort. It's a very exciting time to be alive. I am grateful for you and your contribution.
I think that our Milky way black hole was our "Big Bang" in our local area of space and that there have been and will continue to be many big bangs of varying sizes and ages reliant on the size of the star that created the black hole or the amount of matter it fed on before ultimately reseeds its area in the vast never ending expanse. Star birth and star death with the still unravelled role of black holes, i believe are the keys to a universe of understanding.
Interesting. @@PaulTanner-pc1nj
Just before you mentioned David Kipping, I had been thinking of the video he threw off, almost immediately on hearing they had not secured observing time. Just absolute devastation. Congrats. Moons are increasingly sexy objects.
This robot surgeon will be the great great great great grandfather of the EMH The Doctor. I saw Dr. Kipping interview and then his video giving the fantastic news. Now Fraser Cain again telling about it. I love this "crossovers"
Cool. Thanks for sharing.
Me watching black hole pair section: "Final parsec incoming!"
Fraser: "Right you are, good sir!"
I really liked you in breaking bad! Lol. In all seriousness I enjoy you content. Keep it coming.😁
Re the final parsec problem, Becky Smethurst has a piece on gravitational waves in response to a query about whether these waves interfere like other waves.
Every time I hear talk of extra terrestrial contact, I think of a short story "sentient meat" I forget who wrote it but it's well worth the read
Astronauts are most skilled people outside earth too
Hah, so true.
I strongly doubt that it's just a coreless, formless blob like that. That thing has tremendous gravity well capable of creating a monstrous core.
I can't help but wonder how loud Betelgeuse would be if it had an atmosphere.
It does. The boiling 'surface' is its atmosphere. Even the Sun has acoustics.
Nice, you ain't Patrick Moore, but I didn't realize there was a astronomy/cosmology news channel on youtube. Will be sure to check back soon.
I just have to say how much I appreciate your channel, there's so much garbage out there with generated AI stuff right now youtube feels hollow at times. And I like AI, just when presented by a human, ironic ;)
No AI here. Just regular old human reporting.
😊
The sun isnt AI at 1:01?
That's a simulation, not AI.
@@frasercain yes it didn't look like AI but with recent events sadly it's a question you're just going to have to get use to answering over and over
Fun times ahead when we're going to have to question the difference between ai and simulation. You can look forward to that 😒
Yeah it's fantastic that David Kipping got the viewing time. Work that he's doing is fantastic
cool vid thanks :) my profile is Betelgeuse from my phone, not great lol but i love it
Thank you J.Wbb❤✨
Great video. FYI, before the movie, the name of the star was pronounced BAY-TEL-GAYSE. The name of the star goes back to the ancient Egyptians, who I'm pretty sure didn't see the movie.
Our best answer's will come when the FCST launches... Just waiting for Fraser to fund his Fraser Cain Space Telescope.
Wouldn't that make it the FCST?
@@Yezpahr OOp's Damn fat fingers. I'll fix it
@@RectalRooter Who knows, maybe FRST would've been even better than FCST. It's easier to pronounce and that's important. (it's also why people say 'James Webb' preferably over 'JWST' cuz of the 'double u'.)
And FRST could just be pronounced as Frost.
Yea, your original was better, fuggit XD.
@@Yezpahr Hellz -- Frost does sound good. Nice word play
FRaser Space Telescope
Betelgeuse is extra cool because we can see it, it seems more real than the stuff you can't see with the naked eye.
"Bug Splat" You need to have NASA officially coin that term for a planet/asteroid that crashes into a White dwarf/Neutron Star.
Also just wondering, have the Hubble and James-Webb telescopes ever looked at the same thing at the same time?
Oh neat! I totally missed your collab with Scott last time. Hope you two work together again
13:26 Mind BLOWN!
Run for the hills boys, it’s about to blow!
Great job
It's crazy Hubble is still going. I just can't believe it.
SpaceX may have to fix it someday.
@@user-gv4cx7vz8t No means to do so. Need a cargo bay and a manipulator arm to make repairs without a mission loss.
Digital twinning could be useful for tele surgery. If there was a high fidelity mult-layer scan of the surgical area, one could have almost zero latency when operating remotely.
I love Dr. David Kipping and his "Cool Worlds" ❤
Fraser you underestimate my power! 😡
You were supposed to bring balance to the Universe!!
@@frasercain 😲🤣
@@frasercain"A Prophecy that Misread Could Have Been"
So excited for Dr. Kipping; they got THREE DAYS!!!
I think surgeons are the most skilled and brave persons on Earth.
This is what proves that Star Wars 1: The Phantom Menace was prescient, in that one line from one of Anakin's little friends (i forget which one): "You keep racing, Ani! You're gonna be BUGSPLAT!!!!"
Ridiculously cool!
Very interesting. Would be fun to apply to look at things to make prints on canvases. Pretty stuff?
That website looks very useful
Voting according to what excites Fraser is totally legit!
The scale of Betelgeuse alone triggers my megalophobia, but that boiling animation against hydrostatic equilibrium?
F that.
My megalophobia was triggered by 420 pp, instead of 270. I did not expect it to bee so high
@@EnkaptatonSome say the planet, though not our coastal cities, could make good use of 800 for plant health. The experiment (or cycle) continues.
What is this problem recently that some people have with hydrostatic equilibrium?
@@RideAcrossTheRiverIs this a thing? One never knows which phenomenon the skeptics get triggered by next.
@@EnkaptatonI hope it's not a thing! Next up: flat Sun
I sometimes find a poll while scrolling, but how can I find them specifically? Unless I vote on a poll immediately, I'll never find it later. They're never in my notifications, even though I've subscribed etc.
Cool Worlds Lab will be buzzing at that news. Loved the visual of Betelgeuse .
My favourite 'astronomer's license' of a red giant's photosphere: "red-hot vacuum."
IFT-3 on Pi day, nice!
Wonder if they'll attempt a "rapid" turnaround for an IFT-4 on the anniversary of IFT-1 (4/20)
Beetlejugo is just doin the truffle shuffle. Living his best life.
I believe that the pair of black holes would get closer because of the massive time dilation. It's frame dragging from the effect of the two massive gravitational fields in close proximity that pulls them closer
You are the only person to point at his sources for awkward questions, this includes PBS Spacetime and What the Math, who have answered nothing... As annoying as I am, I thank you for that.
How does one use time on JWST? For example: you have a day to look at exoplanets, are you just given the keys and controller or is it pre calculated by someone who works with JWST? Sounds silly but can you explain? Thank you
17:15 Surely gravitational waves have energy? Maybe creating the ripples in whatever gravity is acts like a kind of drag on the black holes and slows them down.
There are so many cool things that are happening in space and the development of the human race. It saddens me that there are groups of people that will likely never know the awesome progress that is happening in our lifetime because of the inability to admit a fault in logic.
I do wonder how such a massive star exploding changes the gravity well and its effects to other stars near it. Will orbiting planets be flung to the nether with such an explosion.
Thanks.
Betelgeuse is 600 light years away, what we are looking at now happened in the middle ages, around 1400AD
I'm interested in Dr. Kipping's research. More near-term, the fact we can check out what Webb and Hubble are working on is really cool. It's not every day we get to see where our tax dollars are going. More Webb than Hubble in my case, but I have zero regrets funding either one. It's far more entertaining than anything Hollywood has farted out in the past two decades.
I predict the orbiting black holes are direct evidence of the Rocky Horror Picture Show's -- Time Warp
Let's hope there are no more than 2 second delay on the surgical robot and no power or malfunction during a procedure.
Try: "Roiling" as a better descriptive verb for Betelgeuse's apparent activity.
Thanks a bunch for all the news, Fraser! 😊
About finding life out there... People talk too much about it, specially in the UFO community... Hypothesis of collapsing civilization, etc... But, honestly? Yeah, it's going to be fun to watch when it happens, but most people are going to be like... "Oh, really? Anyway..."
Stay safe there with your family! 🖖😊
Perhaps a well timed interview on a well respected popular UA-cam channel assisted the Webb team to choose wisely.
