Betelgeuse Blew Off Its Top In A Catastrophic Explosion
HTML-код
- Опубликовано: 19 сен 2024
- The supernova of Betelgeuse is one of the most awaited astronomical events. Betelgeuse is a red supergiant star on its deathbed in the constellation of Orion. Sooner or later, the star will implode, and our skies will be lit with the aftermath of the event even during the daytime for several weeks. However, no one exactly knows when the star will undergo a supernova. There's a probability that Betelgeuse has already imploded, but since it lies about 650 light years away, the light from that event hasn't reached us yet.
Betelgeuse is one of the brightest stars in the night sky. But in late 2019, it mysteriously started dimming. The dimming was so prominent that one could even notice it with naked eyes. The star's brightness continued to decrease for several months, and people wondered if Betelgeuse's end had arrived. However, the red supergiant star returned to its normal brightness after a few months. When astronomers pointed some of the world's most powerful telescopes at it, they were shocked to see what caused the Great Dimming.
So what happened to the star when it was fading before our eyes? Why was this event so catastrophic for Betelgeuse? Finally, and most importantly, why do astronomers want to focus the James Webb Space Telescope on this dying star?
The 21st episode of the Sunday Discovery Series answers all these questions

I know the chances of Betelgeuse going supernova while I am still alive to see it are slim to none. But man, it would be the sight of a lifetime. Fingers crossed.
Look closer to our star as it starts to accumulate dust as we travel through our current location in space. There are more novas than. super.
650 years if it blew today
Maybe in another life 🤗😁
@@loganthesaint Yeah, but what if it actually blew 649 years ago? 🙂🤞
Cross your fingers and say “Betelgeuse” three times, out loud…
I didn't know if scientists could get a spectra analysis of Betelgeuse, and see if it's close to trying to fuse iron in its core, which of course would trigger a supernova. I tell myself the supernova has already happened and its light is on its way to Earth as we speak. I've really got to see it before I croak!
Ditto! It will be quite a show....
Getting the spectrum of Betelgeuse is a no brainer. But when astronomers say the star is going to explode any day, that means any day within the next 100,000 years. So, I also hope you will live long enough to see it.
Too bad it could be in the next 500 years, unfortunately.
@@mischievous7129
Why 500 years? How about tomorrow Monday? Be a great excuse for taking the day off. 😂
100,000 years
I am Namra. And I want to be Astrophysicst . I just want to Thankyou for providing this much INFORMATION about Space !!!
And also 265th view!!😇😇
You're welcome :) All the best for your journey to becoming an astrophysicist!
@@TheSecretsoftheUniverse Thank you!!😇😇🙏
"Soon" for a star could be 100k years. It would be interesting to see it in my lifetime, not holding my breath though.
I want nothing more than to see this in my lifetime. It would be the coolest thing ever. It hasn't happened for thousands of years, I could only imagine what people thought back then
Betelgeuse has been my favourite star ever since I fell in love with astronomy. Thanks for the great information
Same here my friend it's my favorite star ⭐
I also like Betelguese. My favorite moon in the solar system is Enceladus.
I'm a Stephenson 2-18 guy myself
The Pistol Star.
Everyone's comment appeared twice. What an interesting and unusual glitch! It's nice that Betelgeuse is sticking around for a while. Seems like it had a bit of a Corona-Virus. (Sorry, but I had to say it). 😆
I grew up in the country and Orion constellation was one of the first ones I would always look for. Betelgeuse made it ultra-easy to find. Even though I live in a metro city and all growed up now, it's still a habit to this day to look for it if I'm out at night. It's one of the very few visible ones from the city, too. So it's been interesting watching the dimming. I really look forward to seeing JWST's images of my life-long gazing habit.
From North America you can also see the Big Dipper, which looks like a sauce pan , Cassiopia , which looks lie a W and Auriga, which looks like a Pentagon.
@@sheilanixon913 Yup. I can't see Auriga here. But also, add in Castor and Pollux (Gemini) 'cos I can see them travel across the sky pretty easily as well. Right now, Big Dipper is straight up and slightly North West. Unmistakable as always.
EDIT: Actually I might be able to see some of Auriga. The problem here is city lights, so I only get to see the very brightest. Because of that, it's extremely hard to identify things. It's sad 'cos when I go out to the country, the sky is a whole different thing than the city version. But I still star gaze, even with such limited views, and I am very familiar with my neighbourhood's darkest places for that reason. ☺
you and me, both. :)
The discoveries keep coming. I'm sure there is a lot more to learn about the stars of Orion. Lets hope the JWT will shed some more light on what is happening to Betelgeuse.
Thanks for the presentation, your efforts are appreciated 😀
It's so crazy how possibly Betelgeuse could have already gone through a supernova but we wouldn't know it in present time since it's so far away...space is like the ultimate look into the past in a way and it's almost scary how large it is. Just like we have pictures of galaxies 13 billion light years away...we are seeing those galaxies as they appeared all that long ago in actuality. They could possibly not even exist still for all we know.
I find it insane how that information contained in light can travel for 13 billion years.....
Thanks for this lovely Sunday knowledge.
Always welcome
Thanks dude for telling the secret about the universe
Dying stars actually really make me sad. One must ponder our own beautiful sun and her eventually trip down the same road.
I LOVE this series. The information is delivered clearly, yet with infelction such as curiousity and even excitement and wodner. And the information is never sensationalist, simply offered for us viewers to absorb as we please. I am always eager for the next installment to arrive, which is usually reserved for PBS SpaceTime, lol. |
Keep it up, I know this series will grow in popularity, and be informative to anyone tuning in. Even an 8 year old can understand these videos! [I think so?]
oye vishnu bheekmange
I agree, thank you for not using clickbait wordslike "shocking"....or, "stunning"-which annoys me and is becoming a fad amongst some suspect channels here on you tube which wastes an hour of peoples time without real NEW info r data.
I thinks it’s a robot narrating.
@@jefflyon2020 if that's how you feel about sensationalist clickbaity channels then you're gonna love this channel called cool worlds. every small claim is backed with data and he tries so much to be unbiased.
Another amazing and fascinating video of the great Sunday Discovery Series. Keep up the good work.
Thanks for watching the episodes of the series :)
*Thank you so much for this series!*
I hope we see the explosion in my lifetime!
why
Okay now this is really incredible how this channel gives us great information on the universe we live in, thank you very much
Funny how the Americans call the star "Beetle Juice". Actually it is pronounced [ˌbetaɪ̯ˈɡɔɪ̯t͡sə]. It comes from the Arabic "hand of the giantess", as the Persian astronomer Abd ar-Rahman as-Sufi († 986) listed the star in his catalogue.
Thank you so much for this video, there's some misinformation out there on this subject!! Happy you're putting this out there!!
Please make a video one day about Alaska's midnight sun. I've been reading up on that and it intrigues me so... I have to go there one day before I die.
I'd love to be in Barrow, AK for the Summer Solstice, and see what a 24 hour daylit "day" would be like. Sis had her baby in Fairbanks in September, and said it was light out till 11pm even then.
@@just_kos99 So amazing.... to have light out 24 hours a day for those months and then almost complete darkness in the winter. I definitely have to go there before my time is up.
@@edyann it's only your physical body that dies
@@Jack-r2v9b Well, this physical body that I have right now wants to go to Utqiagvik, Alaska before it leaves to another dimension....
@@edyann yes it would be a great place
So basically what we’re seeing now happened 650 years ago and the star could already have imploded. Well I hope I get to see it in my lifetime although I doubt it. Who gets to say they got to see a supernova and lived to tell?!
I feel sorry for Ford Prefect. Dont Panic!
Great information as always thanks . Hope to hear more about Betelgeuse from James Webb images . The illustrations in this video were really good .
I just love this channel, so visual as well as informative……thanks! X🇬🇧💕X
Just don't say Betelgeuse 3 times in a row.
Just amazing to think this star and all the other constellation possibly have planets orbiting them. Their own comets
This channel deserves more subs
So true !!
Makes me wonder if maybe a rogue object might have impacted the star causing the ejection
Like a black hole, maybe? No planet is big enough to make a dent. But no rogue object is needed. The life cycle of the star sufficient, and produces much larger effects in the longer run.
@@farmergiles1065 i was thinking brown dwarf or gas giant planet, something that would have a solid enough inner core to survive the initial approach to the star
@@albertkustra Well, I can't compute that. It's more a question for a professional with equipment. But if I were to guess, I'd think that it's more likely anything in a small star category or less would simply be consumed by Betelgeuse. It's an immense star, so big there are only 6 (?) like it in our whole galaxy (of how many billion stars?). Stars are not created equal. Maybe the angle of approach would make some difference. But how much impact does a roadside bug have when it flies into a freight truck? That's closer to the mark.
No esoterics. End of life and that happened 50 years ago.
Or an electrified field or an EMP made the star eject enough matter to create a rogue object!
Betelgeuse could have already gone Supernova, it could have happened 100 years ago, possibly 200 maybe even 400 hundred years ago who knows. We still would never witness it unless it blew up about between 547 to 500 years ago or 647 to 600 years ago (Some agree that Betelgeuse is 548 light-years away and other's agree that the star is 650 light-years away) (Give or Take a few extra light-years) for the light to reach us in our lifetime. (depending on your age) How cool would it be to witness the biggest explosion in the universe.
Your 100% correct
Estimates are 100,000 years to 1.5 million years.
I just watched Beetlejuice (the movie) a few hours ago
I wonder if Betelgeuse had any planets that were engulfed, as it grew to its red giant size? 💫
That’s a trick question there probey
Oh jeez I’m having flashbacks to that analog horror short film about the supernova and people freezing in place if they looked at it. If you know, you know
Nice one...Betelgeuse is one star I like the most..coz I can find it out very easily in the night sky...
If really supernova has happened I don't think we will be able to see it in our lifetime...
Mesmerizing..
Great video as usual!! Keep up the good work.👍👍
Thanks! Will do!
A few sun-spots would present as a gradual dimming as the star rotated.
For the brightness to change in less than one rotation of the star by a large percent is noteworthy, if that is what happened.
Do we know her rotational rate?
Great presentation thanks xxx most informative.
FYI "ANYTIME" means anything with in the next 100,000 years.
Betelgeuse has been my favorite star ever since I was in 4th grade. ❤️
Betelgeuse is a star really special to me. Witnessing its supernova, just feels surreal.
Betelguese: "Just Kidding! Maybe next time...."
I suspect it has already imploded. The light will hit us sometime in the next 10 years.
I hope.
That doesn’t make sense because I’m watching it from the naked eye and with the satellite imagery showing two separate stars going back and fourth erratically and I could see the two from my naked eye
@@MrPilgrim
Not sure I understand your point.
The light you are seeing with your eyes was emitted over 500 years ago.
When Betelgeuse goes supernova it will take hundreds of years before the event shows up in our night sky.
Betelgeuse is more than 500 light years away. So, I am predicting that the star already exploded hundreds of years ago. We just don't know it yet
Hope that helps.
I'm not the brightest star in the sky, but I do have a couple questions about this star. When this thing blows, how will it effect celestial navigation, aka astronavigation and will it have some type of climate effect on our Earth?
nope! just a pretty lightshow for a handful of months
@tst ccnt hahahhahaahahah
If Betelgeuse went supernova say last week. We wouldn't see the light for 700 years or longer. The life on Earth won't be affected because the intense radiation emitted by the supernova will have long dispersed. We're too far away. Betelgeuse is more stable than we give it credit for. It'll go supernova, that's a no brainer, but not for another 50,000 to 100,000 years. I think this video was click bait. Gotta find a way to generate that ad revenue....lol!
You have no idea that Betelgeuse has not gone supernova yet.
@Jonah Scrymgeour
You have absolutely no idea. But also the answer would have to be "yes"
If someone uses a star for navigation, and that star is, ya kno, gone one day, then yes there would have to be *some* affect on navigation
I keep cracking up because I now constantly hear beetle juice lol.
Great video anyway
And thank you, very sincerely - For not being a click bait video... It's sssooo appreciated to be given real content!
This is so crazy and cool at the same time, I would love to see the light of the 'aftermath' - but the time-lapse is really confusing.
Since there were huge mass ejection events, should we expect to see a faint nebula around Betelgeuse? Or the star is too bright compared to whatever gas and dust is traveling away from it?
Amazing! A shame we aren't building a fleet of telescopes or even attempting to build a giant telescope on the dark side of the moon. It would be incredible to see what we could find out there.
Very informative, pedagogic and extremely interesting!
Glad you enjoyed it! Thanks for watching :)
I've looked up to the shoulder of my favorite constellation for so long. I'd bet serious money that Orion holds them both far longer than ANY of us will live!
I love learning about pretty much anything, but I do get frustrated at how long some videos can take to convey a small amount of information.
Maybe if everyone on the planet yelled "Betelgeuse, Betelgeuse, Betelgeuse" at the same time then it would supernova!?! :)
Some believe that when it happens we will see it right away but not for 650 years, It takes time for light to travel at that distance,
lol i can't stop hearing beetlejuice and imagining michael keaton...it's cracking me up!
I'm curious about any effect this might have on earth when Betelgeuse becomes a supernova. Thanks for the series, SOU.
Who knows? A magnetar 50,000 ly away had a hissy fit, and the resulting blast from it impacted our ionosphere....and Betelgeuse is much, much closer.
That's an interesting question. Astronomers believe that a supernova within 50 light years from Earth could have a noticeable impact on Earth. A few days ago, I read about the possibility of the second mass extinction (Devonian Mass Extinction) caused by a series of supernovas within 65 light years. But Betelgeuse is ten times the distance. Therefore, it is considered too far to impact the Earth when it undergoes a supernova.
It won't have any effects on earth.
@@TheSecretsoftheUniverse Thank you for that info. Very informative and interesting. Great images too! 🌟🌟🌟🌟🌟🌟
it's got to be much closer that that to have any real impact on the earth, between 50/100 light years
Several months ago, there was a site here that was showing the star, predicting it would explode in 20 minutes, counting down. At zero, the 20 minute countdown began again. I stopped watching several weeks after, and it was still counting down.
I have been hoping I get to see Betelgeus's supernova since I learned why it looked so different when I was a kid. Still hoping.
Betelgeuse, " Ugh, don't feel so good. I knew I shouldn't have eaten that planet last epoch."
The change in the ratio of spectral line strengths does not cause the temperature to drop … instead, the drop in temperature caused the line ratio to change .
Great content
If it does go supernova the debris would be travelling towards us in years to come.
Betelgeuse is about 642.5 light years away from us. So light will take 642 years 5 months to travel from it to earth. The light which is coming out of betelgeuse today will reach us in the year 2663
"It's showtime..."
~ Beetlejuice
Goddamn it, Betelgeuse, what's the holdup?!! I need to bathe in your rays and get my superpowers!
Yeah, yeah... we've heard this over two years ago
They don't know. They are guessing. It say it is not going to exploder at all.
Now lets see who has more credibility.
“It’s Showtime!”
Tis an omen of things to come: one Beetlejuice goes supernova, another leaves office..
Man I love that JWST. Just mwah
Betelgeuse will go supernova after it produces enough iron which migrates outwards and generates an intense magnetic field which interacts with and eventually undermines the stars main central magnetic field causing instability and a collapse.
Betelgeuse won't go supernova until someone says it's name 3 times in a row
Does that material that got dispersed out into space get used to making new stars or planets?
The hydrogen & helium might, but heavier elements are generally locked in the star's core and don't come out till it supernovas. I wonder if we CAN detect heavier elements, eg, if we can see that the star is about to try to fuse iron (which is the 'iron limit', it's when a star goes supernova 'cause it takes energy to fuse iron instead of releasing it).
No. It's too less to form stars or planets. Star formation occurs in extremely massive clouds of dust and gas that span across several light years. This material will ultimately get mixed in interstellar space but is not enough to form stars. :)
Stop it. It could be thousands of years.
Or even millions of years. Why worry?
Ill tell you what happend to Betelgeuse ... sand worms ,damn sand worms haha
Micronova= stars occasionally poop out a planet (it might start as dust). The question is, what is the catalyst?
Galactic current sheet bringing in huge amounts of dust to the system perhaps?
@@MegaArroman Another Observer speaks☄⚡🌪🌌🌠🌌🌪⚡☄
Fascinating. Nice work balancing scientific/common language.
A dip of 80 Kelvin? That seems small and precise.
Crazy to think this all happened in the 13th century!
Explains my new neighbors, the Prefect family.
Dont think its gonna go supernova soon , i mean not in our lifetime ,it still has some life inside 😄
You Sir get a gold star! This was awesome.
So, if it has not happened we would not know for 685 years; and if it has happened it could have happened within 684 years ago. "If it be now, 'tis not to
come; if it be not to come, it will be now; if it be not now,
yet it will come. The readiness is all. Since no man knows..." W. Shakespeare
Let’s not lose sight of the fact what astronomers are seeing now happened about 650 years ago.
Ok, I’ll let everyone know
Why does that fascinate you so? Do you get similarly worked up about a TV show that was on last night but you haven't watched on Tivo yet?
JWT gonna soon give us some more images of Orion Nebula !……🤗✨✨✨✨✨
"Any time now"... 5,000 years from now...
The star that burped.
Awesome
I researched everything I could on this subject when the coronal ejection occurred and scientists have seen this on e before from a similar star! After its second mass ejection, the str went supernovae 2 months later! There’s a chance we may be alive to witness this event. Although it still worried me being so close, due to its Astronomical size! It could wipe out our ozone!
I came because of a misclick... I stayed for the content :)
I am glad I lived in a time when I could behold Betelgeuse as a star... But I want to see him go nova...
*the writer for this is me trying to make my essay long as it can be*
How could anybody possibly think we're alone in the universe. It's so freaking vast and big with billions and billions of galaxies. We can't even get to our own measly moon that protects us by the way and makes life possible here on earth, on regular basis.
It already has. Just that we haven't seen it yet. 642 light years away.
Would be nice when scenes are marked with cgi (at the corner) and data/paper marked as well with the paper date
It would be patronising, anyone with a reasonable level of intelligence can tell what's CGI.
@@robokill387 I get what you mean but it’s not always that straightforward. Especially with the older generation. As real and fake scenes get mixed, it’s not easy to tell sometimes and I’ll admit I fell for it a couple times. There are channels which tag cgi/reenactment versus real footage which adds credibility to the content (it shows some research/source is being done)
We're good. It wend supernova about 17 years ago. We won't see the light from it for about 592 years.
@The Secrets of the Universe
Many people have been speaking about this event. So, it would make sense that you would eventually make this video
Betelgeuse, Betelgeuse, Betelgeuse.. That's it. Now it shall go 🙂.
Last I heard they said it wont go super for a million yrs.
Awesome :) Strange pronunciation of Betelgeuse even in english...
American's have problems with pronunciation or even changing the spelling to suit them. lol
He is pronouncing it wrong. Not all Americans are illiterate.
Gas & Dust obscuring the star. 🌟
having this in the collective may soften the blow when the central star in this system blows off a 'micro-nova' and scorches the surrounding orbits.
now that`s a kamehameha
in the cosmic timescale. "Any time now" could be 100 million years so don't hold your breath
