I honestly don't. I really like the constellation of Orion. It actually means a lot to me personally. I don't want to see it be destroyed. Maybe when I'm on my deathbed, but I wouldn't want to live my remaining life under a night sky without Orion.
@@sfsinverted5175 Obviously the other stars wouldn't be affected. But Rigel and Beteigeuze have a very unique look with one another, and the constellation of Orion wouldn't be the same if one of these two stars were changed. Blow up literally any other star, but not those of Orion. (Okay, maybe not the Ursa Major stars, because future generations couldn't enjoy Hokuto no Ken to the same extent.)
It is an everyday event in the universe. Snuffing out the earth would be the squashing of a grain of sand in the Sahara desert.We are alone out there......
@@FSGoingStraight It's multiple hundred light years away, so it really depends if Betelgeuse has already exploded or not. Maybe it has already and we're just seeing small stages of that change, but that would have been over 600 years ago. It's theoretically possible to see it fully happen, but chances are pretty low.
its kinda like a cosmological craps game in dr frankenstein's office, he may end up with a dragon in place of his shoulder or giant flower. but whatever happens its gonna be a show!
A star about to go supernova "any second" could mean "within a thousand years." Human life spans are insignificant in comparison. Good video - way to manage expectations. ;-)
Not gonna happen. Before it explodes, it has other 'huffing'/'cycles' to go through up until about carbon. We could have year scale warning, when we observe the CNO cycle approaching. Hasn't happened, yet, that I know of. Coolest supernova is still supernova 1987A.
Im taken back nearly 60 years to when I was piggy back on my dads shoulders. He was pointing to and naming all the stars in Orion. Teaching me to identify my first constellation. Teaching me about light years, red giants and nebula. More than anything teaching me how to be the father I would become to my two boys. When he passed, it took all I could muster to look at that part of the sky. To this day I still get tears in my eyes when I do. I've learned that nothing is permanent and how to accept it. Thank you Dad.
It's definitely dimmer, even with unaided eyes. Was about to go to sleep after watching it and some other stars through my telescope and you uploaded a video about it! What a great end to my day 😊😊
Yes it really is. I was comparing it to the brightness of Orion's belt just three days ago and I thought it was dimmer than I remembered, but couldn't figure out why. Then I see this video in my recommendations. Couldn't believe it was confirmed!

There may be several alien civilizations like ours hoping Betelgeuse will explode, but depending on location there may be a few that are really, really hoping it doesn't.
If we are being honest any civilization within it's original goldylocks zone died or moved on during it's expansion before a star goes supernova it expands for example some day our sun will literally obsorbe the earth and likely more planets in our solar system
@Waylen Edge with trillions of planets it's very likely he could be right and that another civilization might be watching that star is less likely but not impossible
@Waylen Edge iv seen alot of theories for why we haven't encountered alien life great filter etc personally I believe very differently and have my own theory on Earth there is a tribe living on an island right now as they have for thousands of years internationally no one is permitted near said island or to make contact as the tribe is very dangerous
@Waylen Edge also if we were to go to said island we would give them illnesses that they're bodies could not resist as they have not developed any resistance to them I believe it is the same for extraterrestrial life if they came here they risk being killed or giving us alien illnesses or us giving them illnesses in the grand scheme of things compared to any extremely advanced civilization we are basically cave men it's entirely possible that several know of our existence but have decided not to make contact yet
Hopefully Betelgeuse went Supernova at least 590 years ago!!!!.... let's make that at least 620 years ago... preferably 640 years ago... the distance is apparently 642.5 ly
@Joker I believe it's actually 642.5 light years away, but yeah i hope it went up 630+ years ago so i can see it in my lifetime. That would be awesome.
@JoshNortonalias Ha are you joking? It will have absolutely zero effect on the earth, all that would happen is we'd see a beautiful bright orb in the sky for a few weeks almost like a smaller, dimmer moon. The moon doesn't affect plants so a dimmer, smaller one won't, and it only lasts a couple weeks anyways. Also supernovas have actually already happened many times throughout history, and I remember reading about records of ancient chinese astronomers writing about a bright blanket in the sky which was identified by scientists today to be a supernova. And also, the debris and shockwave from the star would take over 6 million years to reach us. You have to remember space is fuckin massive!
@@frasercain Since we've NEVER experienced this before in our human history of existence. And never experienced/witnessed the actual series of stages of events of an actual star exploding = supernova goes through.... (in our neighborhood) visible even to the naked eye... I'm thinking since we are experiencing it dimming like this.. it's a precursor. Meaning, It's just the first stage of the explosion... and I believe that it will come to us.. piece by piece, bit by bit, like an old-timey picture slide show machined they used back in the 1800s or the classic View Master kids toy, looked like tiny binoculars but its a picture slideshow. But, if you hit the button slowly, it didn't seem like all that exciting because it wouldn't be moving very fast.. but! The faster you hit it, the faster it moved.. maming it look like a little movie(FPS = A manual frames per second toy, if you will😅). I believe it will resemble something like that to us and our naked eye.. slowly.. picture by picture the full story will reveal itself to us ALL... slowly but surely. I believe it will be like our cosmic(FPS) slide show movie.. cone to life!. 🌠 I believe this to be true. And this too shall pass.
Orion will not be disturbed or destroyed at all after Betelgeuse's Supernova. The Supernova remnant should still be visible for years to come and the other stars are nowhere close to Betelgeuse to have any danger whatsoever.
I'd rather see a human walk upon the surface of Mars. I'm getting kinda old so I don't know if I will or not. I watched Neil Armstrong step out onto the moon when I was 11. I'd like to see someone on Mars before I'm gone.
Imaging photographing Betelgeuse and looking away for a second only to find out right when you were looking away it explodes. And you're one of the first peaple to photograph it. That would be so ****** amazing
I have a theory of what causes the supernova. Three things control stellar fusion, heat, pressure and magnetism. The star produces a lot of iron which migrates outwards eventually generating it’s own magnetic field which undermines the main field causing instability and an explosion.
I was coming out of Kansas City traveling north on I-29 and there it was. I traveled another 60 70 miles pulled over hopped up on the hood of the truck leaned against the windshield and observed it with my binoculars for hours I was in complete awe the entire time

Yes it very well could have, and we wouldn't know it till 640 years after the fact. I personally really hope it did blow at some point 620-630 years ago, so i can see it in my lifetime, that would be awesome.
@@HondaFit-ot5ws Yes, because there is no point in defining any "universal" time. Even if it "has already happened" in the stars local time, it has no effect on us before we can observe it here and it, thus, happens at our local time. Causality stipulates that.
ManDevil i was answering steven pommervilles question on " what if it pops on new years" not how long it will be visible but the point it is first visible on.
I also saw Saturn set on the Moon and Shoemaker-Levy's black spot on Jupiter as well as the supernova in 1987, but a supernova in our own glaxy? ...not yet.
Seeing a supernova in the sky would be quite cool. Almost as cool as a total solar eclipse, which I have yet to see. But the first I read of this was one of those typical cheap headlined articles that are there just to get you to click. At least this video isn't titled "Betelgeuse is dimmer and might..." Good information is good. Clickbait erodes cognizance and ticks me off.
I hope we see it soon too, I don't have long left. I know that when Iron is thrown out it signals the end and it has been doing that for at least the last 10 years as well as Silicon, Aluminium, Calcium, Magnesium and Titanium....So I'm guessing it's already gone but the light and other energies haven't arrived yet.
Hi, I just found your channel, thank you. In looking at your past episodes to vote it gave me a question. Will you please do an episode on Earths space pollution? Maybe some stats like accumulation since we've been satelliting, the defunct just left orbiting, why they aren't smart enough to fall/propell to a specific area when they stop working. Possible projection in 50yrs orbiting along with maybe what our cosmic inhabitants may think of our standard of care to the cosmic environment. Thank you so very much. Keep rockin' :)
The star has already gone Super Nova... 100's of years ago. I suspect that the dimming and brightening of certain stars (including UY Scuti) is related to the explosion of the Super Nova. The "backlight" of the explosion is the brightening effect... and the in between of the waves of the explosion are the moments it dims. The light from behind is being propelled at a faster rate due to the massive explosion and that light fades faster thus giving an off/on or up/down intensity effect of the light. Only the light from the initial moments before has been reaching us. Chances are, the star wasn't even as big as we calculated... rather, we might have calculated its size during the initial moments it was actually exploding. We have yet to see the fantastic light of the actual moment... and when it arrives it might last anywhere from 3 to 6 months. Also, we may have two other stars (which may have gone Super Nova around the same time) show up and stay in the sky with the light as bright as the moon. UY Scuti and Canis Majoris might very well all be in the sky for several months each overlapping in duration. Not sure when since there is no real idea when any of these could have already gone.
Spectroscopy is not used in supernova prediction but why..? -A large star like Betelgeuse increasingly quickly fuses heavier elements until it gets to nickle / iron and then goes 'pop'. (a very big pop!) -You can measure the makeup of a star via it's spectrographic signature -It follows you could use the appearance of 'late fusion' elements to give an estimate on how long a star has got... conceivably some years down to hours So why not? The issue could be such fusion products in the core are 'masked' by the diffuse envelope of the star, but: -Such stars would seem to have wildly powerful convective processes -I presume the far lower density of a red giant compared to main sequence stars would 'slow transmission' from core to surface a lot less even taking the much larger radius in to account -Spectroscopy is very sensitive so, for instance, any evidence at all for neon / silicon would predict an imminent supernova -Maybe this explains why you can't get a time resolution of a few hours but for preceding elements that might predict on the order of (a hundred or so) years... This is such an obvious method there's no way I could be the first person to think of it so what's wrong with my understanding? If anyone has a mo' to explain I'd very much appreciate it, thanks.
4:46 This is the first I've seen this time-lapse, so cool/mind blowing. I'm curious as to what magnitude of a gravitational wave a Betelgeuse supernova might produce....
Perhaps its because the star has moved on to another element to fuse. Not the supernovae inducing iron, but maybe Calcium or something. An element where the fusion of it has a lower exothermic output as the previous elemental fuel.
Hi Fraser, is it possible to know what elements are being fused in the core of Betelgeuse right now, and thereby determine how close it is to the final stage, when it's producing iron?
Not really, Fusion happens in the core which is millions of miles below the star's surface. I takes +100K years for light to travel from the core to the surface.
It's fascinating to think that if we get to see Betelgeuse go supernova, it means that it has gone supernova 600 years ago and it has taken all this time for the light to travel to us. It means that Betelgeuse has gone supernova before it was even discovered by us.
The study was a photometric analysis that only covered a 25 year period. Betelgeuse has dimmed considerably in the past 200 years on occasion, as observed by Sir John Herschel for example. He did not have photometry equipment, but was a first-rate observer. Nothing new here.
Nonetheless, whenever I'm out and about and Betelgeuse is in the sky, I can't help but keep glancing up at it, just for that tiny chance of seeing that moment when it goes boom.
you wont see the moment it goes boom that will have been 642.5 years ago and I wouldn't recommend getting close enough to see the exact moment as that could be hazardous to your health mate LOL
Given that Betelgeuse is around 10 million years old and we've only been around for a small fraction of that, anything that it does could be completely normal and simply part of some long cycle that repeats. For all we know know every 500k years it turns into an Eat At Joe's sign.
I'm a little surprised that no one has questioned how the neutrinos can arrive sooner than the light from the supernova. I mean, nothing can travel faster than light, right? I believe that's because the neutrinos escape directly from the core, but the photons have to get from the core out to the edge of the star, which takes time because of the gas they must travel through. So the neutrinos get a head start. But since they can't quite be as fast as light, more distant supernovas show less of a look ahead. Far enough out, and the light still arrives before the neutrinos.
@@frasercain Hi Fraser. I think you need to do an article on "speed of light". However, my comment remains "it's all philosophical". Or am I wrong? Either way, the quantum stuff makes my head hurt!
"when it explodes" it could have already exploded a long time ago. Keep in mind that what we see has happened a very long time ago and light doesn't travel instantly, so when you are looking at a distant star you are not just looking at a star you are looking at possibly thousand of years of history that has just reached us and could even be a star that have died a long time ago in an event that is still traveling its way towards us
Pricymas Star but due to telescopes and other ways of detecting space like infrared, uv, etc., astronomers can follow it more closely and more accurately than the naked eye
Please.. everything they tell you about space is fake, y'all gotta use common sense.. they claim stars light takes yrs to see if that was when that star moved to a different area you should still see light from the same position but yet when the star is in a different location you see it there instantly! They try so hard to fool us but just use common sense and you'll see majority that shit don't make sense
Question: How close could you be to a supernova explosion before it destroyed the planet? You said the Crab nebula was about 11 light years across, so would something that was 5 light years away from it be strongly affected by it?
If you were within 30 light-years or so, the blast would tear away the Earth's ozone layer and expose us all to the radiation from the Sun and space. So... that would be super bad.
If a star is 650 lightyears away you cannot say if a star is about to explode unless light has infinite speed and it takes no time for it to travel the distance of the supposed 650 lightyears. You cannot observe the Universe in a single time frame snapshot. We don't see the Universe the way it is. The Universe is not a single and absolute time frame. It has an ongoing non constant and imperfect relative time frame that is being relatively developed on the go. If the star exploded 300 years ago we can find out about it in 350 years. Less time if we travel toward it more time if we travel away from it and never if we relatively break the speed of light tagging the star.
640 years for light to reach us? That doesnt even sound right. So if it supposedly takes 8 mins for the suns light to reach us, does that mean that if someone was on the moon with a bright enough light, it would take 15 seconds (making up a number) to reach us?
@@frasercain To observe the time lapse to/from the moon and us, take a look at the communications during any of the Apollo descents to the moon's surface. Apollo 17 is a good example, so look for a file of their PDI descent. What you get are many apparently crossed instructions and comments from Earth and from Apollo. They are not really crossed, which would be disastrous; they just seem so due to time lapse.
Unless *much* closer Betelgeuse, I would think any stellar black hole is going to have a smaller apparent diameter from our perspective than a supermassive black hole in our galaxy (which is behind too much dust/gas for good viewing) or in any of the nearer ones.
I forget which video I've seen where there's a calculation you can do to figure out the size of a resulting black hole, but I am fairly certain it would be pretty small. Even though small, I feel like we would have an advantage here because we'd know exactly where to look to image a small eccretion disk... It would be an exciting turn of events for astronomers no doubt, but probably not more imageable than m87
not enough mass only way it's possible is if there is a second star we are unaware of in the area and that's very unlikely. this other star would need to be something along the lines of a neutron star orbiting inside Betelgeuse.
I dont pay much attention, 30 years ago I probably could have identified a dozen constellations. These days just stop every now again when in a dark place under a clear night sky to wonder at the vastness. {first three lines of "In the City" by The Eagles) I thought something looked different about Orion when I looked at it on Christmas Eve. Like two of the stars were missing. If it does blow, how long between the time it actually went off and when we get the first indication that it did?
Technically speaking the title is not true. The AAVSO light curve generator show that in the 1980s the visual estimates of Betelgeuse magnitude were for a time lower than the present "drop". I'm not giving a link knowing that YT hates them but it is easy to Google up.
Put in the link, I'll approve it. I was referencing the work from the AAVSO which said it was lower than they'd seen in 25 years of continuous monitoring.
The lat 100 years of Betelgeuse magnitude is the second figure in this German blog entry: himmelslichter.net/betelgeuse-in-historischem-helligkeitsminimum/ (there is a translation button which works pretty good for English) The direct link to the AAVSO light curve generator the figure was made with is this: www.aavso.org/LCGv2/
@@Dadecorban Around a red giant? Likely too late long ago. (Though I vaguely remember an Arthur Clarke short story suggesting the Star of Christmas was also such an event...)
Yes but what if the attack ships were on fire because of Betelgeuse, and so the actual explosion happened in the years leading up to 2019, and we just won't see the light for a long time yet?
- After the movie it was mostly Beatleljuice. But Betelgeuse used to be called 'Betel- gyouze by lecturing astronomers back when I wuz a kid. - Just like Myanus is now called Youranus. Although I dont see how.
betelgeuse may have already exploded the star is 650 lightyears away meaning the light we are seeing from betelgeuse is already 650 years old we say its getting dimmer and your right it was 650 years ago this dim spell could also be the star having what is known as a quiet period our star has them in its solar cycle almost like time of the month in star terms . also i believe when a star is about to explode it gets larger as in supergiant /red giant meaning it would get brighter before it finally blew its top .not sure my 5 inch telescope would cut it watching the star haha keep up the good work man love the channel il be subbing
Just note the Supernova SN 1987a a burst of neutrinos was detected in the immediate you minutes maybe hour or so prior to the initial light of the Supernova reaching Earth was detected. A very small first was detected at one particular detector and an even smaller amount in the second detector located on the other side of the planet, indicating roughly the direction in the sky the neutrinos were coming from. The rest is history as they say!
seen many programs where our own Sun will grow to the size of Betelgeuse (and same color) when it begins it's death throws....then starts to shrink back only to regrow as it burns off it's remaining hydrogen....left with helium it shrinks again then eventually it goes boom.....so is Betelgeuse actually a star just like ours that had become a red giant, and the dimming a result of it getting smaller as part of its eventual destruction ???

You stated that the nutrinos arrive before the light how can that be since the speed of light is supposed to be the ultimate speed limit? Or is there a new discovery that they travel faster than light?
Maybe it already exploded, since the light takes ~642 years to reach us. But whenever it happens, I hope we see it-it would direct people to look outward rather than having cabin fever here on earth. Also, It should be renamed to Explodee for the reality of what is to eventually happen because, Science!
So if we look at something through a telescope and it's six hundred light-years awaywhen we look through the telescope are we looking at 6 hundred years ago or since we're looking at it closer in the light has come towards us are we looking at the light that's more closely to current time?
my question is, when there are micro or super nova events, do they cause anything like a dominoes effect against other star systems? for instance, when we observe a shooting star during our night sky, sometimes we only witness one explosion and by the time we visibly observe it, the actual event already occurred long past in our sky neighborhood ancient history; but some of the larger scale events we witness during specific seasons prove to show tons of nightly shooting stars, which leads me to wonder if some cause rippling domino effects, but some don't?? this should be exciting to witness, if it does happen within this generation of earth's life spans. thanks!!!
If Betelgeuse did explode say today it didn't really happen today right? When we look at these distant stars we are looking at the past right because of the time it takes light to get here. So if say it did explode today when did it actually go supernova?
If Betelgeuse is much closer to us then it is not a giant star, then it is a normal red star (ie smaller than the sun) and cooling down, explaining the variance (and dimming) is because it is transitioning from a red star to a flare stare to a brown dwarf. Regards, Daniel
Neutrinos don't travel faster than light, it's just that they're not blocked by stellar material so they can take the direct path out. They get a head start on the radiation.
Awesome video! One correction: at 6:50 you mention that neutrinos travel faster than the light does, which is not correct. Neutrinos have a small but nonzero mass, so going faster than light would contradict special relativity. There was an experiment when they mistakenly thought neutrinos could be faster than light, but they quickly found the cause of the anomaly. More info: en.m.wikipedia.org/wiki/Faster-than-light_neutrino_anomaly
ApertureChromaKey actually it’s not so probable, since there is only approximatly a 0.6% chance that it has already exploded, and even if it has, there is an even smaller chance that we will be able to see it during our lifetime. Unfortunately.
0:40 I am pretty sure that due to the error margins in Hipparcos and other parallax data there is no way we could know the distance of Betelgeuse with two digit accuracy. In fact we probably do not know it even with one digit accuracy. The actual distance might well be, say, 550 lyr instead of 640 lyr which is the figure quoted here.
@@frasercain It would be awesome if we sent a parallax measuring spacecraft to the outer solar system. We would use an earth-orbiting satellite as one end of the measurement baseline, and the spacecraft as the other. It could be tens of AU from earth and therefore give us superior accuracy, but only on stars which are roughly parallel to the line from earth to the spacecraft.
They don't travel faster than light, it's just that they're not blocked by stellar material in the core so they get a jump on the radiation that needs to make a random walk out.
@@frasercain they get a headstart of several minutes before the first supernova light because they can pass through the matter while the first light particles have to "dig" through the matter. And because neutrinos travel with like 99.9999 % speed of light it'll take insanely long for the light to catch up with the neutrinos, so the neutrinos will be detected before the light.
Light can scatter off matter, it already does in our atomsphere in the form of rayleigh scattering. In dense cores of stars, they can get trapped for years or decades repeatedly scattering off the matter in the core before exiting the star's surface.

What DOES (theoretically) pose a risk, is Eta Carinae, which could eject a gamma ray burst in Earth’s direction. We might be looking down the gun barrel of that star... or maybe not?
WAIT so Betelgeuse has 12-20x the mass of the sun, and yet it's many many more times the size of the sun? It's basically a wisp of gas? How is it even lit up at all?

Yeah it might have even exploded by now, but the light just hasn't hit us yet, might take 600 more years for us to notice.
It's not impossible for it to go supernova tomorrow; it's just extremely unlikely.
Still pretty good odds... In stellar terms.
Not gonna happen. Before it explodes, it has other 'huffing'/'cycles' to go through up until about carbon. We could have year scale warning, when we observe the CNO cycle approaching. Hasn't happened, yet, that I know of.

Im taken back nearly 60 years to when I was piggy back on my dads shoulders. He was pointing to and naming all the stars in Orion. Teaching me to identify my first constellation. Teaching me about light years, red giants and nebula. More than anything teaching me how to be the father I would become to my two boys. When he passed, it took all I could muster to look at that part of the sky. To this day I still get tears in my eyes when I do. I've learned that nothing is permanent and how to accept it.
Thank you Dad.

It's definitely dimmer, even with unaided eyes. Was about to go to sleep after watching it and some other stars through my telescope and you uploaded a video about it! What a great end to my day 😊😊

Yes it really is. I was comparing it to the brightness of Orion's belt just three days ago and I thought it was dimmer than I remembered, but couldn't figure out why. Then I see this video in my recommendations. Couldn't believe it was confirmed!

There may be several alien civilizations like ours hoping Betelgeuse will explode, but depending on location there may be a few that are really, really hoping it doesn't.
If we are being honest any civilization within it's original goldylocks zone died or moved on during it's expansion before a star goes supernova it expands for example some day our sun will literally obsorbe the earth and likely more planets in our solar system
@Waylen Edge with trillions of planets it's very likely he could be right and that another civilization might be watching that star is less likely but not impossible
@Waylen Edge iv seen alot of theories for why we haven't encountered alien life great filter etc personally I believe very differently and have my own theory on Earth there is a tribe living on an island right now as they have for thousands of years internationally no one is permitted near said island or to make contact as the tribe is very dangerous
@Waylen Edge also if we were to go to said island we would give them illnesses that they're bodies could not resist as they have not developed any resistance to them I believe it is the same for extraterrestrial life if they came here they risk being killed or giving us alien illnesses or us giving them illnesses in the grand scheme of things compared to any extremely advanced civilization we are basically cave men it's entirely possible that several know of our existence but have decided not to make contact yet

Everybody wants betelguese to explode
Constellation of orion: N O
I have a theory of what causes the supernova. Three things control stellar fusion, heat, pressure and magnetism. The star produces a lot of iron which migrates outwards eventually generating it’s own magnetic field which undermines the main field causing instability and an explosion.

Possible projection in 50yrs orbiting along with maybe what our cosmic inhabitants may think of our standard of care to the cosmic environment. Thank you so very much. Keep rockin' :)
Thanks! Welcome aboard. We actually did a video on space pollution many years ago, but it's probably time to do another one.
The star has already gone Super Nova... 100's of years ago.
I suspect that the dimming and brightening of certain stars (including UY Scuti) is related to the explosion of the Super Nova.
The "backlight" of the explosion is the brightening effect... and the in between of the waves of the explosion are the moments it dims.
The light from behind is being propelled at a faster rate due to the massive explosion and that light fades faster thus giving an off/on or up/down intensity effect of the light.
Only the light from the initial moments before has been reaching us. Chances are, the star wasn't even as big as we calculated... rather, we might have calculated its size during the initial moments it was actually exploding.
We have yet to see the fantastic light of the actual moment... and when it arrives it might last anywhere from 3 to 6 months.
Also, we may have two other stars (which may have gone Super Nova around the same time) show up and stay in the sky with the light as bright as the moon. UY Scuti and Canis Majoris might very well all be in the sky for several months each overlapping in duration.
Not sure when since there is no real idea when any of these could have already gone.
You're an astronomer I take it?
Spectroscopy is not used in supernova prediction but why..?
-A large star like Betelgeuse increasingly quickly fuses heavier elements until it gets to nickle / iron and then goes 'pop'. (a very big pop!)
-You can measure the makeup of a star via it's spectrographic signature
-It follows you could use the appearance of 'late fusion' elements to give an estimate on how long a star has got... conceivably some years down to hours
So why not?
The issue could be such fusion products in the core are 'masked' by the diffuse envelope of the star, but:
-Such stars would seem to have wildly powerful convective processes
-I presume the far lower density of a red giant compared to main sequence stars would 'slow transmission' from core to surface a lot less even taking the much larger radius in to account
-Spectroscopy is very sensitive so, for instance, any evidence at all for neon / silicon would predict an imminent supernova
-Maybe this explains why you can't get a time resolution of a few hours but for preceding elements that might predict on the order of (a hundred or so) years...
This is such an obvious method there's no way I could be the first person to think of it so what's wrong with my understanding? If anyone has a mo' to explain I'd very much appreciate it, thanks.
They elements are being formed deep inside, so they're not visible on the surface. That's why neutrinos are a way to see what's happening in the core.
it's breathtaking to image how close betelgeuse is to us, in comparison to other stuff in the universe.
Yup, but there are lots of other potential supernovae, and some are even closer.
4:46 This is the first I've seen this time-lapse, so cool/mind blowing.
I'm curious as to what magnitude of a gravitational wave a Betelgeuse supernova might produce....
It would be interesting to see. It would supposedly result in a high-frequency wave that our current detectors could perceive.
Perhaps its because the star has moved on to another element to fuse. Not the supernovae inducing iron, but maybe Calcium or something. An element where the fusion of it has a lower exothermic output as the previous elemental fuel.
And to think that was actually happening when Christopher Columbus was barely a glimmer in his fathers eye.
Hi Fraser,
is it possible to know what elements are being fused in the core of Betelgeuse right now, and thereby determine how close it is to the final stage, when it's producing iron?
Not really, Fusion happens in the core which is millions of miles below the star's surface. I takes +100K years for light to travel from the core to the surface.
It's fascinating to think that if we get to see Betelgeuse go supernova, it means that it has gone supernova 600 years ago and it has taken all this time for the light to travel to us.
It means that Betelgeuse has gone supernova before it was even discovered by us.
Yup, but we can't know until the light gets here.
The study was a photometric analysis that only covered a 25 year period. Betelgeuse has dimmed considerably in the past 200 years on occasion, as observed by Sir John Herschel for example. He did not have photometry equipment, but was a first-rate observer. Nothing new here.
Betelgeuse exploding: “It’s showtime!”
Darth Tiberius 😂 nice!!
Nonetheless, whenever I'm out and about and Betelgeuse is in the sky, I can't help but keep glancing up at it, just for that tiny chance of seeing that moment when it goes boom.
you wont see the moment it goes boom that will have been 642.5 years ago and I wouldn't recommend getting close enough to see the exact moment as that could be hazardous to your health mate LOL
How can you be into cosmology, yet have no idea how light works? 🤦🏼♀️
@@Lessthanthreeedm How can you not realise I was referring to the moment that the light arrives?
I thought it was my eyes starting go when I looked at betelgeuse a few weeks ago. It was noticeably dimmer
Just the opposite, you have really good eyes.
Given that Betelgeuse is around 10 million years old and we've only been around for a small fraction of that, anything that it does could be completely normal and simply part of some long cycle that repeats. For all we know know every 500k years it turns into an Eat At Joe's sign.
I'm a little surprised that no one has questioned how the neutrinos can arrive sooner than the light from the supernova. I mean, nothing can travel faster than light, right? I believe that's because the neutrinos escape directly from the core, but the photons have to get from the core out to the edge of the star, which takes time because of the gas they must travel through. So the neutrinos get a head start. But since they can't quite be as fast as light, more distant supernovas show less of a look ahead. Far enough out, and the light still arrives before the neutrinos.
That's exactly right. The neutrinos are able to get through the stellar material while the radiation gets slowed down. They get a head start.
@@frasercain Hi Fraser. I think you need to do an article on "speed of light". However, my comment remains "it's all philosophical". Or am I wrong? Either way, the quantum stuff makes my head hurt!
"when it explodes" it could have already exploded a long time ago. Keep in mind that what we see has happened a very long time ago and light doesn't travel instantly, so when you are looking at a distant star you are not just looking at a star you are looking at possibly thousand of years of history that has just reached us and could even be a star that have died a long time ago in an event that is still traveling its way towards us
Pricymas Star but due to telescopes and other ways of detecting space like infrared, uv, etc., astronomers can follow it more closely and more accurately than the naked eye
Please.. everything they tell you about space is fake, y'all gotta use common sense.. they claim stars light takes yrs to see if that was when that star moved to a different area you should still see light from the same position but yet when the star is in a different location you see it there instantly! They try so hard to fool us but just use common sense and you'll see majority that shit don't make sense
its only 640 light years away so it probably hasn't
There's only a window of a few hundred years here, not millions. It's possible it already blew, but not mathematically likely.

"It's Show Time!" 💥
TH-cam happen in 2022 what's the difference with two other different Stars it's going to be so time ☀️》💥
Question: How close could you be to a supernova explosion before it destroyed the planet? You said the Crab nebula was about 11 light years across, so would something that was 5 light years away from it be strongly affected by it?
If you were within 30 light-years or so, the blast would tear away the Earth's ozone layer and expose us all to the radiation from the Sun and space. So... that would be super bad.
yeah bro, so if Proxima Centauri goes nuts, we're done ;D
If a star is 650 lightyears away you cannot say if a star is about to explode unless light has infinite speed and it takes no time for it to travel the distance of the supposed 650 lightyears. You cannot observe the Universe in a single time frame snapshot. We don't see the Universe the way it is. The Universe is not a single and absolute time frame. It has an ongoing non constant and imperfect relative time frame that is being relatively developed on the go. If the star exploded 300 years ago we can find out about it in 350 years. Less time if we travel toward it more time if we travel away from it and never if we relatively break the speed of light tagging the star.
640 years for light to reach us? That doesnt even sound right. So if it supposedly takes 8 mins for the suns light to reach us, does that mean that if someone was on the moon with a bright enough light, it would take 15 seconds (making up a number) to reach us?
The Moon is about a light second away. But yes, if you wanted to play a game with someone on the Moon, you'd have 1-second ping times
@@frasercain To observe the time lapse to/from the moon and us, take a look at the communications during any of the Apollo descents to the moon's surface. Apollo 17 is a good example, so look for a file of their PDI descent. What you get are many apparently crossed instructions and comments from Earth and from Apollo. They are not really crossed, which would be disastrous; they just seem so due to time lapse.
What if it leaves a black hole behind? How much more "imageable" would it be than the synthesized image from M87 ? Would Ligo flinch if it forms?
Unless *much* closer Betelgeuse, I would think any stellar black hole is going to have a smaller apparent diameter from our perspective than a supermassive black hole in our galaxy (which is behind too much dust/gas for good viewing) or in any of the nearer ones.
I forget which video I've seen where there's a calculation you can do to figure out the size of a resulting black hole, but I am fairly certain it would be pretty small.
Even though small, I feel like we would have an advantage here because we'd know exactly where to look to image a small eccretion disk...
It would be an exciting turn of events for astronomers no doubt, but probably not more imageable than m87
not enough mass only way it's possible is if there is a second star we are unaware of in the area and that's very unlikely. this other star would need to be something along the lines of a neutron star orbiting inside Betelgeuse.
It would be to small to image.
Ligo would not flinch at all.
not massive or dense enough
Maybe Betelgeuse has a longer 50 year variable cycle.
What if it already Exploded?!
640 Light years away from us. If we see the Supernova right now, it means it has already gone supernova 640 years ago.
My thought s exactly
Yeah but doesnt really matter. All we want is to see it exploding in our lifetimes, lets hope that it has already exploded.
I dont pay much attention, 30 years ago I probably could have identified a dozen constellations. These days just stop every now again when in a dark place under a clear night sky to wonder at the vastness. {first three lines of "In the City" by The Eagles) I thought something looked different about Orion when I looked at it on Christmas Eve. Like two of the stars were missing. If it does blow, how long between the time it actually went off and when we get the first indication that it did?
Even though I learned the constellations 30 years ago, they're like familiar friends when I look up.
Technically speaking the title is not true. The AAVSO light curve generator show that in the 1980s the visual estimates of Betelgeuse magnitude were for a time lower than the present "drop". I'm not giving a link knowing that YT hates them but it is easy to Google up.
Put in the link, I'll approve it. I was referencing the work from the AAVSO which said it was lower than they'd seen in 25 years of continuous monitoring.
The lat 100 years of Betelgeuse magnitude is the second figure in this German blog entry:

Just note the Supernova SN 1987a a burst of neutrinos was detected in the immediate you minutes maybe hour or so prior to the initial light of the Supernova reaching Earth was detected. A very small first was detected at one particular detector and an even smaller amount in the second detector located on the other side of the planet, indicating roughly the direction in the sky the neutrinos were coming from.
The rest is history as they say!
seen many programs where our own Sun will grow to the size of Betelgeuse (and same color) when it begins it's death throws....then starts to shrink back only to regrow as it burns off it's remaining hydrogen....left with helium it shrinks again then eventually it goes boom.....so is Betelgeuse actually a star just like ours that had become a red giant, and the dimming a result of it getting smaller as part of its eventual destruction ???
It's pronounced, "Beetle-juice", like the movie, eh? 😂
I’ve heard people pronounce it both ways. I’m not sure if one of the two is considered correct.
The name of the star is Arabic - so use their pronunciation if you want to be more exact...
I've heard it pronounced "Bait'l-geese."
He did it on purpose so Micheal Keaton would't show up. 😂😂😂
@@bluebrook32 As an Englishman i can confirm it's pronounced "beetle juice". As if there's a strange man of in the distance milking beetles and bottling their juices.
You know that you really want to call it Beetle-Juice, just give in, repeat after me, Beetle-Juice, Beetle-Juice, Beetle-Juice.
The correct pronunciation is "Bettle-gurz"
Paul Peterson Bet al Jews ...
You are not supposed to say that three times. What is wrong with you?
Ah,Tim Burton's movie, my childhood, the same actor played both Batman and Beetle juice , and there was also a really good beetle juice cartoon, very funny, those were the days, the golden Era ..........
You're right. At first I was also annoyed how he pronounced Betelgeuse. But, if I would have made the video (I'm Dutch) I wouldn't have been bothered by the beetlejuice you're talking about.
Do you know how the old Greek pronounced Betelgeuse ????
It's the content of the video that matters, not the pronunciation
of Betelgeuse.

Could this be do to a ring of dust entering our line of sight versus the star dimming
Jason Gannon or did just now throw off a massive shell of dust?. Hope it can wait for the James Webb telescope
Yes. It could even be a cloud of gas erupted by Betelgeuse itself.
You stated that the nutrinos arrive before the light how can that be since the speed of light is supposed to be the ultimate speed limit? Or is there a new discovery that they travel faster than light?
No, the neutrinos pass through the stellar material without interaction, while the radiation is held up. So it gets a head start.
Maybe it already exploded, since the light takes ~642 years to reach us. But whenever it happens, I hope we see it-it would direct people to look outward rather than having cabin fever here on earth. Also, It should be renamed to Explodee for the reality of what is to eventually happen because, Science!
7:05 Is there an APP connected to this Super Nova Early Warning System?
John Johansen not yet, but there is an alert, albeit via the good ol email: snews.bnl.gov/alert.html
@@BarryRijkse Thank you, Barry!
FYI --- if you say Betelguese 3 times a crazy ghost appears.
I just tried that and nothing happened :/
You already covered my thoughts on this Fraiser: C'mon and blow up already. I want to still be here to see it
So if we look at something through a telescope and it's six hundred light-years awaywhen we look through the telescope are we looking at 6 hundred years ago or since we're looking at it closer in the light has come towards us are we looking at the light that's more closely to current time?
my question is, when there are micro or super nova events, do they cause anything like a dominoes effect against other star systems? for instance, when we observe a shooting star during our night sky, sometimes we only witness one explosion and by the time we visibly observe it, the actual event already occurred long past in our sky neighborhood ancient history; but some of the larger scale events we witness during specific seasons prove to show tons of nightly shooting stars, which leads me to wonder if some cause rippling domino effects, but some don't?? this should be exciting to witness, if it does happen within this generation of earth's life spans. thanks!!!
Next up: "Isaac Arthur on 'Colonizing Betelgeuse'"
It's just a matter of time.
"Dim and Dimmer" - the movie
Just don't mention the prequel and sequel.
Sounds like a adult movie title ;)
@@anonb4632 Prequels and sequels generally only elicit an ominous silence from my end ...
@@thespectator2976 Then again so does "The Colour Purple".
"Betelgeuse could go supernova any day to 100,000 years."
Me: So you are telling me there is a chance?
I hope it doesn’t pop .. that’ll ruin my wide field Orion images (oh well I guess I can always photoshop it back in 🙄 lol)
If Betelgeuse did explode say today it didn't really happen today right? When we look at these distant stars we are looking at the past right because of the time it takes light to get here. So if say it did explode today when did it actually go supernova?
If Betelgeuse is much closer to us then it is not a giant star, then it is a normal red star (ie smaller than the sun) and cooling down, explaining the variance (and dimming) is because it is transitioning from a red star to a flare stare to a brown dwarf. Regards, Daniel
The last time a star went supernova ,Christ was born.
Could you elaborate please
A star that shone for a short time,it's all in the bible just read it.Had to be a super nova,what else?
Problably....good point but we dont know...this super nova is going to be for the return of him.
Not Done that wasn’t the last time, he mentions more recent ones in the video like the 1054 supernova.
the dimming is being caused by the alien Armada which coming toward us!
It’s been exploded...just takes time to see it here due to light years
Yup.
I am surprised that the media police did not pull your video. It is blasphemous to say neutrinos arrive to earth before light does. Brave man.
Neutrinos don't travel faster than light, it's just that they're not blocked by stellar material so they can take the direct path out. They get a head start on the radiation.
Awesome video! One correction: at 6:50 you mention that neutrinos travel faster than the light does, which is not correct. Neutrinos have a small but nonzero mass, so going faster than light would contradict special relativity. There was an experiment when they mistakenly thought neutrinos could be faster than light, but they quickly found the cause of the anomaly. More info: en.m.wikipedia.org/wiki/Faster-than-light_neutrino_anomaly
No, neutrinos sill travel slower than light, it's just that they're not blocked by stellar material so they get a head start on the radiation.
Ok, yeah it may go nova, or, I ain't saying it's aliens, but it's aliens!
**Alien Race laughs in mega-structure**
Betelgeuse would be a dangerous place to keep your megastructure.
Maybe it already died and we haven't seen it yet.
Probably
ApertureChromaKey actually it’s not so probable, since there is only approximatly a 0.6% chance that it has already exploded, and even if it has, there is an even smaller chance that we will be able to see it during our lifetime. Unfortunately.
Most likly
@@yunusaliakbas9192 ur a moron
0:40 I am pretty sure that due to the error margins in Hipparcos and other parallax data there is no way we could know the distance of Betelgeuse with two digit accuracy. In fact we probably do not know it even with one digit accuracy. The actual distance might well be, say, 550 lyr instead of 640 lyr which is the figure quoted here.
Gaia has been doing much better accuracy than Hipparcos. I'm not sure if they've measured it yet, though.
@@frasercain It would be awesome if we sent a parallax measuring spacecraft to the outer solar system. We would use an earth-orbiting satellite as one end of the measurement baseline, and the spacecraft as the other. It could be tens of AU from earth and therefore give us superior accuracy, but only on stars which are roughly parallel to the line from earth to the spacecraft.
That would be next level. 😀
"Neutrino being faster than light"
Sure of that ??!!
They don't travel faster than light, it's just that they're not blocked by stellar material in the core so they get a jump on the radiation that needs to make a random walk out.
@@frasercain they get a headstart of several minutes before the first supernova light because they can pass through the matter while the first light particles have to "dig" through the matter. And because neutrinos travel with like 99.9999 % speed of light it'll take insanely long for the light to catch up with the neutrinos, so the neutrinos will be detected before the light.
6:58 Neutrinos faster than the speed of light? Pardon me?
No, they still go slower than light, it's just that they're not blocked by the core of the star so they get a head start on the radiation.
I believe it has something to do with the random walk difference for neutrinos and photons.
Light can scatter off matter, it already does in our atomsphere in the form of rayleigh scattering. In dense cores of stars, they can get trapped for years or decades repeatedly scattering off the matter in the core before exiting the star's surface.
@@frasercain I wish the video would've said "sooner" instead of "faster" because that line got me too.
Yeah, in retrospect, I should have spent a lot of time making this more clear.
She's ready to blow
I really hope I get to witness it I look up often
Me too. 😀
What DOES (theoretically) pose a risk, is Eta Carinae, which could eject a gamma ray burst in Earth’s direction. We might be looking down the gun barrel of that star... or maybe not?
WAIT so Betelgeuse has 12-20x the mass of the sun, and yet it's many many more times the size of the sun? It's basically a wisp of gas? How is it even lit up at all?
It's producing so much radiation in its core that it pushes the material out that far.
Fraser Cain wow, hard to imagine the scale of these things. It must be very wispy towards the surface? Would it even have a distinct edge like our sun?
This thing goes supernova. Michael bay: am I a joke to you.
Michael Bay would probably be the one who caused it.
