Day 3,648 of people saying "Something weird is happening on Betelgeuse"
Well, given the lifetime of stars being millions or billions of years old. It's possible that the actual supernova won't happen in our lifetimes. Scientists are just hoping it does.
There is a chance the supernova already happened but the light hasn't reached earth
This guy doesn't understand galactic timescales
... but now back to the Phlegraean Fields! 😁
@@heatherflaherty3360to be fair it’s a couple hundred light years away so it might take a couple hundred years
So technicaly Betelgeuse could already have gone supernova right now and we wouldnt even know until 400 500 years from now
Or it did it hundreds of years ago and we'll see it soon
millions of stars have gone supernova that we still see as stars. doesn't really matter about the distance and light speed, the only way we'll really know is when we can see it
@@littlegirlblue9829I desperately hope that we will see it soon. I really want to see a Super Nova in my lifetime
Not necessarily. It may have already gone supernova and we’ll see it soon meaning it went supernova 400-600 years ago.
634 years to be exact.
Beetlejuice Beetlejuice bettlej……..
AHHH

NOO!!!😭😭😭😭😖😖
🤷🏿♂️
Exactly what I was thinking! 😂👍
_"Can we study Betelgeuse using the James Webb telescope?"_ _"No. It's instruments are too sensitive for its intensity."_ [Hubble telescope] *_"Hey. ya guys know I ain't dead yet, right?"_*
Hubble should be "open sourced' to EVERYONE for $150/hr. I have a few "experiments" to conduct from here, as my workstation is now the same power as a 1993 SGI 10k "Infinite Reality" system , used to confab the first cable modems. But that was just a day job....
@@htos1avyou must be joking 😂
What's needed to study it, is a big mirror and sunglasses. Webb forgot his sunglasses. What would you expect from a NASA administrator?
It is being observed across many EM wavelengths, including the infrared. As a matter of fact, observations in the infrared during the dimming in 2019 (in the visible spectrum) remained steady, so the dimming wasn’t in the infrared, just the visible light part of the spectrum. If I remember, Hubble does have some capability in observing in 5he near infrared.
Perhaps we need a spacecraft that points at Betelgeuse at all times, streaming data constantly?
“Betelgeuse is Boiling” is now the name of my new drone folk album
Actually, Betelgeuse WAS boiling. It may even have gone nova already. As it's more than 650 light years away what we're seeing happened 650 years ago.
Actually...you sound like a absolute cringey douche trying to make a point everyone already knows
It hasn't. We aliens oftern pass it. 👽
I don't think super giants go Nova
@@nighthawk0077 no, but Supernova. Thats a difference.
Beetlejuice is a giant waste depository for toxic waste generated by the artificially created stars used to power the hyperloop slip stream gates to traverse the galaxy by exiting local space time and traveling outside the curvature of the 3rd dimension of our universe and local time flow is stopped while outside the confines of space time, in the foamy environment of the higs field where the multiverse can be observed and quantified, before you pop your gravity bubble and the graviton waves push you through the space time membrane , back into our own universe that we can exist in. Most universes in the multiverse lack the necessary constants and energy needed to support biological so called life. Were we to accidentally poke a hole into the wrong universe, we would evaporate into basic sub atomic particles and cease to exist. So if could give me a lift to Saturn, I can gather enough materials and deuterium from the wrings to build my own gravity slip stream to access the higs field and get back to my dimension hopefully without being pushed into the wrong universe again. I'm tired of the clown universe of evil and chaos. It was fun the first couple millennium, but its still the clown universe and I hate clowns. Get me the hell out of here. I also can make your interdimentional gravity drive operate more effectively and prevent accidental disentanglment and quantum evaporation and other types of interdimentional errors and potential fuckery that can cause unwanted non existence and cascading universal ripples and mergers with unstable universes like clown universe. So come pick me up, and then we can go back to the universe of order, harmony, and swarms of winged nympomaniac super model hookers and portable blow job maidens . You know , those hot chicks with no vocal chords and a desire to be naked every time they see a star ship land. Clown universe sucks and has none of the great stuff found in the orderly universe we were robbed from. Get me out of here
I’m just amazed how scientists are able to figure things out with just a fuzzy image of a light.

So... you're basically saying that we are detecting the death of a star by SNEWS SNEWS
It all comes down to when Betelgeuse is producing iron. All stages of fusion release energy up to iron. Iron fusion absorbs energy and is the death of supergiant stars.
There might have been a collision with a planet sized object heavy in iron
If I remember correctly, the iron producing phase is so fast you would say it is the beginning of the supernova, not any kind of warning of one.
@@michaelbarnard8529 Each phase of fusion the amount of time in that phase is shortened by 1/2. The fusion phase of iron lasts less than a day.
I don't normally subscribe to these types of channels because they're always romancing, exaggerating and speculating. I just want to hear facts, and this video delivered
I can already see the headlines if it goes nova in the near future: “Betelgeuse breaks physics”, when really, we had no idea what would really happen to begin with. This is why we need to be careful about using the word “theorize”, when colloquially we mean “speculate” or even “estimate”. Whatever happens, I would bet that it will completely surprise the science community.

I live in coastal mountains N/W of Monterey Bay, know for great stargazing. You can see Betelgeuse in a very defined pulse/ vibration seeming to change colors. Fascinating! ⛰🌲👨🌾🇺🇸
Yeah, what you are seeing is caused by the Earth's atmosphere.
@@macs787is right. What you’re seeing is the distortion from the earths atmosphere. That’s what they mean in the song Twinkie twinkle little star. The only telescope I know of that has software to compensate for the atmospheric distortion is the one in Hawaii. Could be more but that’s the only one I know of.
Correction, something weird has happened on Betelgeuse. Approximately 600 years ago.
I don't see the need to point out the speed of light when talking about distance objects like this. If we see a meteorite hit the moon, it's not really necessary to mention that it happened 12 seconds ago. There's literally no way of getting information faster than light
Don't see the need to point out the speed of light for every discussion about distant objects* I don't think it needs a correction, when we see it dim or something, that's when it dims, that's when it effects us.
No, because "when" depends upon where you are. Only the speed of light (causality) is constant, so the idea of simultaniety is meaningless over such distances.
It was pulsing a few months ago. I just happened to be watching on a clear night.
I totally saw that. Think it was early February. It was most definitely pulsing to the naked eye. I watched it for like 35 minutes convinced I was about to see a supernova lol.
Don't forget that any, so called events on betelgeuse, that we observe, happed 650 years ago
Right, so saying „something weird IS happening…..“ sounds odd
This is true..were seeing light from along time ago. Example..they say there might be life on certain planets,..were that planet and star might be in it's time and space will be different from our perception..that's how far the space and time differ..which is then just a guess...
For me, the "now" is defined by my position in the universe.
It's a star. What happens to it that we see now could well take 650 years or much longer, with various phases. Remember that other stars are in more advanced states than Betelguese, like VY Canis Majoris.

When the fusion process begins making iron, the supernova happens in a few seconds as the fusion does not generate enough energy to support the mass. Gravity always wins.
main sequence stars with iron in them usually become a black hole. Betelgeuse is a supergiant, so this comment makes so much sense.
Time always win!
Anyone else stare at it for more than 30s, trying to will it to go?

Imagine being one of those who is living close to this star, oh dear.
Anything that we see happening to Betelgeuse now, actually happened 600 years ago.
I HAVE BEEN WAITING FOR THIS EXPLANATION Back in November I recorded a super zoomed in video of Betelgeuse in an area with little to no light polution, in the video I acknowledge just how crazy bright it is and that it's flashing blue and red. You can even make out the bubbly effects in the video, I did not even think astronomers were studying Betelgeuse right now because the last thing NASA reported on it was that it dimmed significantly and went from being the 10th brightest star to the 20th something which was back in 2019, and now it's even brighter than it was when it was the 10th brightest star, so essentially I spotted and recorded Betelgeuse's bubbles AND the fact it got so much brighter - months before NASA even reported these things, and for that I am very proud of myself, as soon as I went inside home after making the recording, I tried as hard as I could to find any news about the stars current state but the latest studies on the star were in 2019 so I never was able to find any explanation...until now

In some cultures Betelgeus was a Hell dimension. When it explodes you could thonk of it as "the gates of Hell being thrown wide"

nah, hell in our universe already exists and is much closer to Earth. A certain evil twin of ours named Venus. Surface temperatures hot enough to melt lead (800°F, 426°C) a consistent state of dim dawn brightness because of the thick yellow sulphuric acid clouds blocking sunlight almost no wind at all on the surface, meaning the heat thrives even more thousands of volcanoes across the surface its day lasts longer than its year rains sulphuric acid, but because of the extreme surface temperature, it evaporates before even touching the ground an atmospheric pressure almost 100× that of Earth's no magnetosphere so it's in a constant state of bombardment from the sun's rays if you were to step on that planet without a protective suit, you'd be crushed, scalded with every breath and badly burned all over, and would die of asphyxiation due to its atmosphere being made up of carbon dioxide, nitrogen, and sulphuric acid, no oxygen. you'd be dead in seconds

It's spinning faster, so it's shrinking. Helium fusion is ending. It won't be long until it goes supernova.
Well, he's getting a sequel...ofc he would be boiling with anticipation...or anger depending on how the sequel goes
We've never observed a star forming. But they explode every 26 years on average. And we've observed that. So when someone says a star formed in a solar nebula. That's just an educated guess. Another interesting thing is if we count the exploded stars in our galaxy there are about 6000 years worth of dead stars.

did it already die but we dont know yet?
That light that reach us is hundreds and hundreds of years old...so quite possibly.
It's approximately seven hundred light years away So if it does explode in the near future technically. Yes, we would know until the light gets to us But it's still close enough to where we're able to get a decent ammount of data

It's nearly impossible to detect Neutrinos from our own sun. Theory says they should be everywhere all the time but even then they are extraordinarily hard to detect. They tend to go right through just about everything including the detectors. In a numbers game determined by the inverse square law .. detecting Neutrinos from our sun is extremely difficult making detecting them from light years away .. well .. impossible.
Come on!, I observed the 1987 supernova event without a telescope. 1987A is my Supernova.
Betelgeuse has the bubble guts 😮 💨
What I find fascinating is that supernovas apparently happen in seconds, so regardless of the time it takes it’s light to actually get here, in our sky, it would also seem to visually change in seconds to our eyes as well, even if it happened long, long ago.
At first i thought the thumbnail was a delicious biscuit.
Maybe the mass ejection was so large that's what got it spinning.

@@Taijitu527 We only have real data on just one sun. All the others, if any others exist at all, are just tiny streams of photons. Nothing real can be learned from them other than their frequency and direction of travel.

There is no way to determine the shape of Betelgeuse nor whether or not it displays aggression.

@@Usnveteranstacker Starologist? All it takes is basic physics. The only physical evidence we have from Betelgeuse is light, and not very much of it. Astronomy describes the edge of the universe in more detail than Oceanographers describe the ocean floor. We have reams of data from the ocean floor but only a tiny portion has been explored. We have next to nothing from deep space.
Beetlefuice began to dim so it came to be known as the great dimming of Beetlejuice… and that’s the best they got? It’s no wonder they went into astronomy, marketing was just not their specialty.

I thought you said penetration
... it's been said already... it's an old new, around 640 years old ... it may not be there as we speak ...
Fascinating !
I hear you saying that we have figured out that we can't figure it out while desperately hanging on to scientific knowledge? The only constant is change.. expect the unexpected. The only "problematic" process is prediction 💫
Is it not possible for someone from my local council to "pop over" to Betelgeuse 🌟 to find out what all the fuss is about !?.
You mean something already happened on Beetlejuice since it takes 650 years for us to see or detect it. It may have gone supernova yesterday but we won’t be alive to witness it.
It’s very easy for stars to boil, in a near vacuum the boiling temperature is lowered. Try it with some water up in the mountains. Since stars are made of mostly hydrogen, I use the water analogy.
As far away as it is, it could have already gone supernova centuries ago, but we don't know it yet.
Let's hope it went Super Nova 649 years ago so that we can observe a Super Nova next year in our sky! Observing a Super Nova must be so cool!
Close up Images ? "Betelgeuse / Distance to Earth: 642.5 light years" Hmm . 👀
If the star explodes and Orion loses one shoulder, it would look like Pushpa.
Rotation is not measured in miles or kilometer per second, but in angular velocity, rpm or degrees per time. Only flatearthers measure in absolute speed.
I heard if you say Betelgeuse: not beetlejuice, three times. our star/sun will rapidly grow in mass and go supernova. I wouldn't try it because I like the warmth we have right now, not radioactive microwaving of our planet
Thanks!
The animation at 2:22 was interesting and I've never seen tat before. Was that a real simulation of what Betelgeuse is like?
Supernova simulation of the dust being thrown out.
Please upload Astronomy events of May
when they say it happened at a particular time (jan for example), is that what is happening actually at that moment ... or did it happen x light-years ago and just reaching us in jan?
Way back in the earlier days of personal computers (PCs), I found a program for the Atari that simulated motion by changing (rotating) colors on a water fall. This seems to be what is happening with Betelgeuse. With the convection of temperatures creating red-shifts/blue shifts, this has the same effect. (Basically what you had already said, but in a simpler, repeatable fashion.)
Was finally explained by the theory....I didn't think theories proved anything!😁
Just tossing it out there but wouldn’t it be entirely possible that the reason this star dims the way it does could be planets that are still rotating around it but inside it’s up layers? I mean when the sun expands and swallows all the inner rocky planets, it’s still a slow process and the planets would take a considerable amount of time to burn up. The planets would still want to orbit around it. So if that were the case, then this dimming would be the same as if the planet were outside of it. What we might be seeing are cores of this star’s planets that are still orbiting the star. They are just orbiting the star within its outer layers and when they get on the side facing earth it cause the star to dim.
Beautiful appraisal 🙏
High Five! 🙏
It needs to pop already, i wanna see a supernova before I die
im came here for new info about Betelgeuse.. it seems im still al the way up to date except for the rumor of supernovae. i already knew it was boiling from our perspective.. did it go supernova?
Thanks for the info that it can't be observe using JWST 😁
Do we have any idea How long from (SNEWS) detecting neutrinos until we would witness visible supernova explosion? Seconds? Minutes? Hours? More?
Neutrinos would arrive a few milliseconds after the light from the supernova
You MEANT to say "something weird was happening to Betelgeuse 642 years ago, (it's 642.5 lights years away so we're watching what Betelgeuse was doing in the year 1382; it may have exploded a century ago, we just can't know yet).
So the super powerful telescopes in 1382 should have noticed it. Dang slackers of 1382.
It doesn’t matter how far away it is… what matters is what the light that is reaching us shows.
You’re nitpicking
maybe went nova hundreds of years ago 😂
so what? may be we'll see the explosion TOMORROW
Our planet is spinning faster by 1 sec/ year now. Is there a correlation between the two celestial bodies undergoing similar changes at the same time?
probably not
The Betelgeuse Star Explosion was a much in the News in last Year 2023 and still people talks about it. What is really happening on the Betelgeuse, when it exlode and can we see that with only the Naked Eyes? 💫💥
If we're lucky. I sure Am hoping to get to see the final flashy photons of an uncontrolled fusion reactor, sent breakneck speed this away So Very long ago!! Yes, please! We'll have to be very, very lucky. I hope I hope I hope...
You certainly will be able to see it with the naked eye. It’s already one of the brightest stars in the sky. When it goes supernova, it will be so bright, you’ll be able to see it during the day for probably a few weeks. At night, it will be as bright as the moon.
Future after supernova. (Magantar) Possible depending on Magnetic Field strength.
Is there a star that ISN'T "boiling"? Once a star stops boiling, it collapses in on itself and stops being a star
What about the types of neutrinos being emitted now?
I want to work on the team that makes up funny acronyms for space things, AKA Funny Acronym Research Team or F.A.R.T for short
The rotation could be effected by the remnant of a large body (planet or star remnant) continuing to be consumed, inside of the corona.🤷🏻♂️
Betelgeuse is 548 light years from us. Who knows how long ago it’s been boiling since it’s that far away. I mean we see light from galaxies that took millions of years to get to where we can see it. I’m not worried about Betelgeuse.
Beetlejuice is more fun to say and most people are more interested because of it.
The models of supernova's show that a star has to go through this boiling bubbling process first before it can explode. The models just don't work to produce a supernova without this happening. Doesn't mean the models are right but that is what they show. There is still a very small risk of a gamma ray burst from a Betelgeuse supernova despite being 650 light years away. It is almost certainly not big enough to produce a gamma ray burst and its explosion poles would have to be pointed directly at Earth but there is still a one in a billion risk. You would have to be in a concrete type basement for a few hours to escape this risk and everyone in your hemisphere would be dead on the streets anyway if it happened and there would be no electronic equipment left intact (including your car and your phone and electricity) so don't worry about it. You don't want to live through a gamma ray burst.
If a gamma ray dangerous enough to kill everyone on a hemisphere hit earth, being in a basement wouldn't save you. Gamma radiation is very persistent, and also if it were such a high amount of gamma radiation it would fry the ozone layer, in which case i'd advise you to stay miles underground for centuries until the ozone layer might have recovered.
All this time I thought it was spelled Beetlejuice...
Is it entirely possisble that a star could be trapped within a star? I've pondered the the notion for some time now, especially when it comes to the odd behavour of Betelgeuse.
My dad has dementia and calls me constantly telling me betelguese is about to explode. He finds stupid shit like this and doesn't know any better.
This is once in an lifetime event when Beetlejuice explode to become supernova ❤❤❤
“ It’s show time “ !
Our best hope, is that Betelgeuse is in a disc shape scenario. & Pointing away from us?
Given the size solar flares .it's core has had time to age which will mean trillion s of tons of high grade gold
so..can our star shot out dust like that sometimes? is that how planets are really formed?
I don't understand why people don't realise that it's in all probability part of the lifecycle of a red giant star, this is why it's dimming and brightening. Like the sun at the centre of the solar system. If anything it needs to be studied and recorded so that we can expand our knowledge of the cosmos.
The day some 700,000 years from now when Orion the Hunter is renamed The Well Hung Hobbyhorse. (@10:50 - 11:08)
My eyes are never naked. My eyes always wear my eyelids.
People debating if it's about to die when it could be already doing supernova right now and we don't know it yet. Until the light register arrives to our neighborhood in a few years.
What kind of rotational speed is listed in km/s ? RPM, sure; radians per second, sure; km/s ... not so much! Now if you were talking surface velocity, which is fine for a hard surface like the surface of the Moon or Mars or Earth, but is kind of hard to apply to a bag of gas like Jupiter or the Sun. But, either way, if you meant surface velocity, say surface velocity.
Ok, Betelgeuse travels thru the cosmos, would it not collide with other bodies as it travels... Would this suit up it's spinning momentum?
Space is way too big. The chance of Betelgeuse hitting something is miniscule. Just a comparison: the distance between the sun and Proxima Centauri is about 28.000 times the diameter of Betelgeuse.
Wait couldn't the Chandra telescope be used to measure its changes?
Hurry up and ka-boom already!!!!! I've been waiting for this star to pop its top for 20 years, and I'm getting a little tired of it! If it all goes back to normal AGAIN, I'm giving up on the geuse.
