- Betelgeuse, a red supergiant star known for its significant dimming events and the potential to explode in a supernova, located in the Orion constellation. This video covers the behavior of Betelgeuse, highlighting its size, luminosity, and the recent observations that have led to speculation about its imminent future.
If we see Betelgeuse go supernova now, it actually happened roughly 500 years ago. 🙂
612 ly... so when I read the video title I was like ... nothing... nothing would happen.
@@ozgott1415 You are correct. That title, though. It would look cool for a month or so, and Orion would never be the same, but that's about it.
@@ozgott1415 642.5 light years away..
Betelgeuse, that's pronounced 'beetlejuice', exploded 500 years ago as retribution, not for the Peasant War like we first thought but for what King Henry the VIII said to Pope Clement VII when the Pope would not grant the divorce. Turns out this slight exploded Beetlejuice way back then.
I'm just keeping it 💯
@@EinsteinKnowedItbruv what are you even saying? It exploded because it became to unstable as a stellar body, not because of anything else.
If it exploded right this second.........nothing. I wouldnt live to see it because of the time it will take for the light to reach us.
Exactly 💯 💯 💯
It may have already happened and the news is only just about to reach us-in our lifetimes!
He means for us
@@billgalen9014 Probably not. Estimates go out to roughly 100k years left in it's lifetime before it goes supernova.
@@Stubbies2003 its been dimming and brightening oddly and nobody quit understands why, it may be prepping for a supernova in our lifetimes, (meaning its explosions light may reach here soon)
We'd all wait 700 years to have surprised expressions
Burst? These things "bursst"?
@@mikefanchin ...huh, what?
640 light years away
no, when we see it happen it really happened 642.5 years ago, the light from it just got here.
@@justaguy-69 my stupid joke was because the video title says "burst right now" pay attention
Astronomers, the ones who know what they're talking about, are saying that it's too far away to hurt us.
If it COULD hurt us, what do we do?
Hide under the desk?
@@rdelrosso1973lol duck and cover
@@rdelrosso1973if it could. Nothing. It would be revelations. The atmosphere would blow off like a screen. We would be exposed to space radiation. Imagine a nuke but from above and the size of the sun. Luckily we wouldn’t get much energy cause usually energy dissolves in waves in all directions. So the further we are the less degree of “energy” we would receive.
The only star close enough to hurt us is our own....
Astronomers calculate Betelgeuse at some 700 light-years distant, its diameter bloated in size to about out to Jupiters' orbit in diameter...the axis point off about Fifteen degrees. This axis point is important as jets of energy are expelled along its axis...these jets can dangerous at immense distances.
When you look at the constellation Orion, at Betelgeuse, you see it not as it is now, but as it was centuries ago. It takes light that long to get from Betelgeuse to here.
yep, its probably already exploded but if were lucky it exploded around 500+ ly ago and we might get to see it in our life time.
A star went supernova in the Pinwheel Galaxy visible in 2023, I'm lucky enough to have taken a picture (as did many others) of the Galaxy prior to and after the supernova. It only looked the a new star popped up but it was really cool to see with the knowledge of what it actually was.
I was taught that it's to far away to have any real effect on us. Although, it would be bright enough to light the night sky for two weeks. It would be lit up like dawn.
I hope I live to see it, even if it kills me. 😅
It is. It burst in 2019 and these folks still think it’s “going” to burst. It had zero effect on us even after blowing out a majority of its load.
None of the stars near us will ever affect us.
It will be as bright as the full moon at night and will be visible for several weeks. We will also be able to see it in the day.
@@gymhayes4613 a Gamma Ray Burst will scorch the entire side of the Earth that it hits...within the few seconds or minute it lasts.
@@josephcernansky1794 betelgeuse is too far. The other local stars wont pop before humanity is gone. This is my jam bub.
Your video title promised some wild speculation on what would happen to the Earth today if Betelgeuse went supernova... And it did not deliver! I should have known better when I didn't see an apocalyptic thumbnail image for the video.
how does the video title promise anything about earth? the title doesn’t mention earth at all
It doesn't mention earth but I had to check. The speculation about every single other thing in this scientism propaganda piece is void of any provable facts. Sad.
It's because absolutely nothing would happen. It's too far away
With my luck, I'll probably be having a nap and miss the whole thing.
It will be visible for a while after it happens, something like a month I think.
with the earth worms !
Or get rudely awakened, with a start...
You're missing it right now lol
There will be a bright light in the night sky. There will be a brilliant light show for anyone here to see. Over a period of months to a few years it will gradually fade from view. Beyond that, we are in no danger from Bettalguese.
Exactly it's too far to pose a serious danger for Earth. If it blew within 20 lightyears we would not be so lucky.
Just don’t say it three times! 😅
It won't do a thing except give our posterity a short but spectacular show.
Before working in astrophysics were you the voice of Huckleberry Hound? That would be so cool
when you have black holes and neutron collisions eclipsing its host galaxy by folds of magnitude it truly puts into perspective our tiny little star in how easily life can be extinguished by such an explosion.
"now" in astronomy means mostly our lokal time when we know or see it.
It's so fascinating how we haven't even really left our own backyard yet we already know this much about the life and death of certain objects across the cosmos. It's truly impressive.
In the universe there's no such thing as now.
Um, when something happens now, that's called now. Effects wouldn't happen for a long time. But still, when they happen it'll still be now at that time.
Jeffery Epstein didn’t kill himself.
When faced, it's now. Probably good :)
Awesome comment!!! Eloquently brief. And yet profoundly deep!!!! ☮️☮️☮️
How soon is now?
This gives you an idea about distances in space. Light can travel around the earth about 7 times a second, betelguise could of already exploded before Shakespeare was born, the light just hasn't reached us yet 😮🤯
It might have already gone supernova but since it's about 640 light years away, we wouldn't see its light image for (640 - x) years. x equals the distance in light years the supernova light image has already traveled in the vastness of space.
Interesting and informative. I would suggest one thing, though. When you cut to captioned illustrations, they are not on screen long enough to both read the caption and look at the picture. Either give a few seconds longer to each slide, or remove the caption and speak it, while the viewer looks at the picture. Other than that minor point, this was most enjoyable.
If Betelgeuse went supernova today, we wouldn’t see it until about 640 years from now.
We would know nothing for over 500 years since it's over 500 light years away.
At 650 light years away, nothing would happen except a very bright spot in the sky for a brief time.
Yep, we would be seeing something like a movie that was filmed six hundred some years prior.
Great video first time seeing your channel in my feed liked and sub’d…. When bettlejuice does go nova do we know if there are any planets in its orbit and will we be able to detect the impact on them??? Many thanks for sharing 🍻👍
Van Gogh inadvertently captured a supernova in his painting “Starry Night”
For some reason I always trust the British accent for narrating space/scientific videos over the American....
Not just “American accent” BUT THE ACCENT FROM THE SOUTHERN STATES. IT IS INHERENTLY ANTI-INTELLECTUAL, AND SLOVENLY. THE PRODUCERS OF THIS PROGRAM SHOULD NEVER HAVE ALLOWED THIS DISTRACTING NARRATOR.
Wow racist much?
Neither British nor American are a race. @@troyholdenvoices
That's a very scientific approach!
Haven't watched this channel in a minute and this new voice is very disconcerting and I don't like it much.
Edit: I've never watched this channel before-- I thought this was a 'What If' video... 😳🤷♀️
great video, thanks for posting
Thank You for the Great Tour
It's 2 months later, and watching it happening live online now
Excellent narration!
The probability that supernovae themselves can induce detectable ripples in spacetime detectable in gravitational waves is pretty unlikely to occur and to be detectable would likely require a LIGO type observatory in space on a magnitude of close to the Earth - Moon orbit. Ninety-Five percent of the mass of a Super Nova stay relatively close to the star during the gravitational collapse of the star and resulting expulsion of the outer layers of the star resulting in much of the mass collapsed into a white dwarf but still gravitationally stable in essence with relatively much the same spacetime gravitational annealing in place but expanding only due to the materials shed.
You kidding? We aren't ready if it freezes, and a water pipe bursts.
In answer to the title question, as far as we are concerned, not a lot. Because even light takes time to travel the vast distance, it would take a number of years for that light to reach us. So, Betelgeuse could explode now, and we wouldn't see the light of it until it reached us...
As for the tag, 'We're not ready!', we don't have to be. Betelgeuse is too far away from us for any harmful effects to reach us. At best we'd have a second bright light in our sky during the day, but that's about it. That and the fact that the constellation Orion will forever be missing a key component, that is.
Depends. Gamma-ray bursts are dangerous much farther away than only 600 light-years, which is this star's maximum distance. If the burst is pointed at where our general direction will be (400-600 years in the future) there may be trouble.
When it happens millions of years from now, it will STILL be now at that time
@@brianhammer5107 Yeah, but the chances of this happening are practically non-existent.
By "now" they mean when we see it happening.
@@brianhammer5107 You still missed the point. Carolyn is pointing out that the whole "we're not ready" is click baity and she would be 100% correct. Even if a GRB was produced by Betelgeuse going supernova and somehow pointed directly at us what in the world are you, or the video maker, suggesting we can do to "be ready" for it? Or are you suggesting that everyone make a "bomb shelter" underground made with thick lead walls in the super rare chance that not only does that supernova happen but also makes a GRB pointed directly at us?
Are the extra dimension springs for space time to rebound
We wouldn’t know about it for quite some time. It’s that whole speed of light thingy. 👍
It may already have happened, and we could see it today.
Shouldn't we be able to witness countless supernovas at all times due to the sheer volume of stars out there?
AWESOME!! Can't wait!!!
"What Would Happen If Betelgeuse Burst Right Now?"
Absolutely NOTHING to us, at least not until 642.5 years from "right now".
724 light-years away from Earth. We're safe, completely safe.
Obviously you think betelgeuse is a balloon
Well made video!
Great video❤
We should have a few years warning by monitoring any untoward effects on Sirius.
The dimming observation happened 5 years ago. That is hypothesised to be dust emission. The question is how long does a supernova take to happen once a significant material emission has taken place? If this question can be answered then the supernova time could be guessed. The whole thing is like the date of release of prepaid games. Speculation.
I recall reading an article that stated Einstein never called general relativity a theory , it was a German scientist in 1906 who said it was !
When Einstein released the completed general relativity in 1915, the title of the paper was "The general theory of relativity"
He released special relativity in 1905, but that wasn't a theory,.
@@Robert-do3cd I stand corrected ! Thank-you .
A spectacular spectacle.
A leading astrophysicist has said that we MIGHT see this with binoculars...maybe!
It would be nice display, especially in the evening.
If people could stop using "theory" when they actually mean "hypothesis", I would be so happy.
its light is fluctuating again , the current hypothesis is its boiling
You would see it in around 645 years because that is how far away it is in light years.
It would take radiation traveling at the speed of light to reach us from Betelguise exploding about 752 light years. Any blast debris would take thousands of years to reach Earth.
What happens if Beetlejuice go supernova, ONE HELL OF A LIGHT SHOW.
I work graveyard shift and watch it nightly hoping I will see it as it blows. 😱💥
🙇♀️”..Amazing!”
I understand that astronomers say that gold is produced not buy a supernova but by neutron star collisions
It would be a spectacular spectacle!
This video told of what happens when a star experiences a supernova explosion and what the cosmic particle emissions from a supernova could do to any nearby planet's biosphere and atmosphere. It would have been interesting if the video how Betelgeuse going supernova might impact Earth, 600 or so years after it went supernova.
I’m currently watching the live streaming for it right now!!! lol that’s wild.
What spectral stars nova and hypernova?
If it happened right now, we wouldn't see it. Those in approximately 700 years will see it though
If it exploded just now, what would happen to the earth? Nothing right now! Betelgeuse is some distance from us, Astronomers suggest 422 +/- lights, but the distance is debatable. Some astronomers suggest that the earth is too far from us but honestly that can be debatable. Let’s say it did blow and it has since gone supernova, we will not know for 500 years. However I saw a story about Polaris the north star, that star is acting up. But if we were much closer, better pray….
Last I checked, Betelgeuse was tilted the wrong way for a supernova to affect Eearth much, at least as of now. If we were looking into one of its poles when it went off, we'd be in trouble, though…
"Burst"? It's a star, not a pimple.
Though Beetleguese is unstable, it could last another 1.000 years, or even 10,000 years or 100,000 years before going Nova. Nobody can predict when it will explode .
If it exploded this very second i understand that we will not see it for many years to come due to the massive distance light has to travel in order for us to see it. But could the JWST see it fairly soon after it actually exploded due to it being able to look extremely long distances?
05:07 The star emitted this large dust cloud roughly 700 years ago and we saw it in 2020 because of that huge distance. So if Betelgeuse bursts right now we wont notice for another 700 years. But if we were to see it in our lifetimes it would be quite a spectacle, something our modern human society has not experienced yet.
There. Are u happy? Everyone dies" LOL
The human race WILL NOT last forever.
That's what Palpatine kept telling Anakin in his nightmares. Everything dies, even the stars.
What about kilonovae and hypernovae and novae?
We are likely to experience a micronova from our own star, the Sun, before we experience Beetlejuice going supernova.
A pretty light show !
In space no one can hear your supernova explode.. But definitely see it 😄
Why dies the narrator say type "eye" a and "eye" other letters, but when he speaks of Type II suoernova, he then switches to numbers, saying two instead of double "eye" or "eye 👀 eye."
Strange.
Or supernova and supernov A. Makes me want to throw my phone
What he is actually saying is "supernovae" which is the plural of supernova. How he could know that and yet confuse Type1A supernova as being Type IA, I have no idea.@@zanetrukk
@@deedubya286I strongly suspect this is a text-to-speech bot reading a script. For me, the giveaway was the strong southern/texan accent, yet it pronounces "nuclear" correctly.
I wouldn’t worry about the spelling. It takes 600 years for the letters to get here….
I think if the star were to start to go supernova, it would take centuries to do so
I heard that the star already exploded and it’s expected that we can see it soon
If it exploded right now, we wouldn't know it happened in my lifetime.
If it burst right now we'd have 642 years to get ready. However, if we SEE it burst today....
What if this even happened 642 years ago???
Actually because BeetleJuice is NOT a Main Sequence Star and is in its Red Giant phase and because its distance is greater than 320 light years away (the maximum for deriving distance by Parallax), there are some rather large error bars on its distance, somewhere between 550 light yrs and 650 light yrs. One might think that when Voyager traveled beyond Uranus, it would have faced its cameras at Beetlejuice to get a more precise Parallax distance measurement. Maybe that did happen.
Oh sure, Betelgeuse and the billions of other stars whose true distances are unknown
We wouldn't know about it for 10,000 years.
IF it does, we all would "sorely" miss it.
**Science, especially Astrophysics, is The Universe Trying to Understand itself**
If Betelgeuse burst right now we wouldn't even see it for 700 or so years, provided humans are even around then.
We live in a universe where objects are placed unbelievably vast distances apart, and the speed of light or rather the speed of electromagnetic radiation is such that it takes massive amounts of time for this radiation to travel between these sparsely spaced objects. So Beetlejuice is over 600 light years away from planet Earth. Anything that happens in current time at Betelgeuse will take over 600 years for us to observe it. It could have already had its supernova, but the electromagnetic radiation that we would observe of that event hasn't gotten here yet. Everything that we observe about our universe is in the past.
If it bursts now we won’t have to worry about it for a few million years.
I bet that the light from a supernova is so bright, that it could destroy your eyes if you looked right directly at it, much like looking at a solar eclipse without filters.
Not from this far away it wouldn't
If we witnessed Betelgeuse exploding now how long ago would it actually have happened, 700 to 800 light years ??
about 734 years (approx)
By "now" they mean "when we see it happening".
You are mixing up your terms. Light years is in reference to distance. Like Beverly said it would be measured in years distant not light years.
if it went bang right now we wouldnt know, its like that dimming it had not long ago for us happened around 500 years ago
Remember, the idea that red giants go supernova remains an unproven hypothesis based upon unproven theories of stellar evolution and computer models. I’m not saying it’s wrong, just that we don’t know it’s right. There are alternative theories.
Realy I like this video its so interestyng
I love the graphics
CZcams really needs to have a rating system that reflects viewer interest based on how long they view the video and likes vs dislikes. This video actually has nothing to do with the title.
If Betelgeuse decided to burst right now, you would not see a supernova for around 700 years 🤷
Betelgeuse too far away to cause us any harm. It will just be very interesting to see.
Space and time become other things when taking the scale of galaxies and the universe into account. "What would happen if Betelgeuse burst right now?" - well - we wouldn't know for another 640 years . . . so, who knows - the whole thing could've gone off anytime during the past 600+ years - so, "right now" doesn't mean much . . .
Well, Betelgeuse is 700 X 6 trillion miles away, let me calculate when to get out the marshmallows.
It likely already went supernova a long time ago. The light just hasn’t reached us yet.
If it exploded when henry vlll was alive we still wouldn't know
To answer the question posed by the title: if Betelgeuse burst right now, then it would burst right now. And it would take 500 yrs for us to see it because it’s 500 light-years away from us.
If it explores right now, it will hit the earth in 500 years time and we will be long gone by then and flying around in space ships
a bright light in the sky, not visible on Earth for a long time
If Betelgeuse burst right now we would still have 642,5 years to prepare. 🙂
