Betelgeuse Explained
Вставка
- Опубліковано 14 тра 2024
- At the beginning of 2020, the world held its collective breath as a nearby behemoth star, called Betelgeuse, start to dramatically fade. Could this mean the star is about to go supernova? With the recent flutter of news activity settling down, we are now finally starting to understand what might have really happened. Today, we take a deep dive into what makes massive stars like this tick, and then get into how we might have now finally come up with answers to this bizarre event.
An educational video written and presented by Prof. David Kipping.

Damn... THIS is the difference between your standard UA-cam scicommer and a professor who breathes this field everyday
Hmm, it's almost like his PhD in the field makes a difference in the quality of content or something.
As opposed to, "I read this on Wikipedia and. . ."
Seriously tho. Everyone on youtube has a degree from google.
Here I am at 75 years old wishing I had studied astronomy especially with professors and instructors like this congratulation. Dave in Phoenix Arizona USA
@@khaccanhle1930 Give me the visual data to. ah, view, then let's all make an "educated" guess (Open Source). Unfortunately, the data is held closely to the tit and you nor I cannot theorize as gracefully as the, ah, upper echelon, of data theorists/analysts/monkeys. Of whom may, or may not, understand enough to theorize to the extent of the interwebs. Or at least willing to believe so...
I'd go even farther than that, there's plenty of working physicists who post UA-cam shows or lectures (or TV documentaries or whatever), but being a science educator takes a different skillset than being a scientist, and they don't always coincide. Possessing both skillsets is what separates folk like Sean Carroll or Mr. Kipping from the rest of the crowd.
Carl Sagan said it first a long time ago: "The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff."
zoomers hate carbon because it kills polar bears, imagine if kids were taught how h20 causes more heat retention than carbon?!?
“Zoomers”. That’s a good one.
@@tinto278 bad attempt at trolling
@@chairmanofthebored8684 Zoomers are generation Z, they are brainwashed kids and young adults.
@@tinto278 OK boomer.🤣
Recently, several articles have been written about Betelgeuse dimming and the conclusion that has been reached is that a large cloud of dust moved between the star and Earth. That is why Betelgeuse’s brightness in infrared hasn’t changed. Infrared light will pass through clouds of gas and dust without being affected much.
As professor stated, iron (element 26 on the periodic table) is the end of the fusion chain in a star. No element higher on the periodic table can be made in a star. The only way heavier elements are created is in a supernova explosion. The heaviest element being uranium (element 92), which is why it is the heaviest naturally occurring element on Earth. Silver, gold, platinum were all created in a supernova. But the iron in our blood and the core of the Earth came from a stellar core (maybe supernova too). This is direct evidence that another star went supernova, blew out its guts, and those guts became the seeds for our entire solar system including creating another star, our sun. The only question that remains about that event is what happened to that progenitor star?
betelguese burns 2 stroke fuel oil!
Sorry to necro your comment, but the current consensus is that most of the elements heavier than iron were actually created from the collision of neutron stars. There apparently isn't actually enough of those elements around to conclude that supernovae are the primary source. They'd be far more abundant if so.
Heavier element have also ben produced in plasmoids in experiments like ken Shoulders evo's toroidal plasmoids
it's always dust
The thought of a star being the size of Jupiter's orbit around our own sun is mind blowing. It's so hard to conceptualize.
Poorly worded.
@@jarlwhiterun7478 Extremely
@@jarlwhiterun7478 Actually worded perfectly... due to the SIZE of Betelgeuse its diameter extends to what would be our Jupiters orbit around our sun, which means Earth wouldn't exist.
When our sun finally blows out (Billions of years from now), it will extend beyond Jupiter.
@@jarlwhiterun7478 Not at all. The diameter of the star is about the same as the diameter of Jupiter's orbit. It's a perfect comparison.
Another young star's life ruined because of greed. shame.
Your comment gave me a smile!
@Chris noonan Nice little poem! Title it 'The Betelgeuse Limerick'!
My brain trembles
F for the star
Ha ha ha! So funny. Thank you
"You are in essence, made of ash".
Ah so I'm a Dark Souls character after all. That's why life is so hard sometimes.
Mood
Indeed, you beef jerky-looking knight, you.
In a cosmetic sort of perception ya lol
space dust
That is not the only reason...
I absolutely love how you explained this to us, the regular folk. You made such a complex subject that is at the tip of the tip of the tip of the iceberg - as far as what we know and understand so far - easy to understand. Thank you for the explanation, fixing my existential crisis, and sharing your amazing knowledge. You’ve earned a subscriber!
I heard something about a binary system where one of the stars is about to go supernova which will send a beam of radiation perfectly aimed towards Earth that knocks off the ozone layer.
@@iamasalad9080 as far as i know that is probably not very good
Still waiting on it
Jesus, then ending of this was so well worded and actually brought me to tears. Scientific inspiration. We were forged in the heart of a massive star, sacrificing itself to spawn life across the cosmos.
And everything we see happening in Betelgeuse now has already happened 700 years ago.
That's melancholic as fuck.
It already did it's thing
Someone always seems to point that kind of thing out in the comments and apparently people applaud in admiration every time.
@@6ettomendes The fact itself isn't melancholic. People, songs or sad stories are.
So Betelgeuse may already be dead, but we don't know yet
I love how you answered the question "Could I jump off and escape Betelgeuse", saved me a lot of searching and math that I'm not qualified to do anyway
@simpsons Bart why did you have to copy/paste this crap all over the comment section? Get. A. Life.
@simpsons Bart wut?
I chose my year 9 big project on Betelgeuse.
This video has hugely contributed to my understanding of the star.
Thank you to the creator!
I cannot believe nobody has put together a Wikipedia page for you Professor, I find your videos engrossing, and a challenge to my vocabulary, worry not for someone will do it well before your demise. Yes I occasionally have to pause your presentation to check a word, but then that is education, and even at 65 I am getting better at scrabble. I figure I will have a good 20 years of learning left in me, and this is what I have deduced will ward off dementia, and I find everything about space engrossing. So keep them coming and enthrall us with your excellently pleasant delivery and grammar, having been raised in the 60's when a regular trip to the library was mandatory for a good education, I cannot get enough of the internet and your chosen field of study.
So is a particularly dense part of it's Oort cloud out of the question, with Betelgeuse being so young the cloud may still be a long way from spreading uniformly in it's orbit ?
People are worried? Am I the only one who stares up at Orion and shouts BLOW UP ALREADY!?
No, no you are not.
Yup and I WANNA SEE IT.
lmao your not the only one!
You and me both... 😔😕
Would be awesome event in our lifetime
Outstanding. Sir, your delightful use of poetry, philosophy and passion is most welcomed. You have a voice for speaking, not just talking, you had my attention from beginning to end. Thank you.
Trae Cummings Thanks, it was the connection between science and philosophy that really captured my attention when studying physics so I try to make sure this is included in my videos.
Yes
@anurag And you find that funny? That is a tragedy. It could possibly harbour life. Plant, bacteria or animal.
@anurag never seen it.
@@traecummings9853 It's a book. 'The Hitchhiker's Guide to the Galaxy'. Read it sometime, it's good.
This video felt like it was an hour long, and i mean that in the BEST way possible. im not sure how you were able to pack so many details into this video while keeping it at a relaxing pace. Well done!
Recent research concluded that this star will supernova in actual decades, not centuries. Yup, in our lifetimes
Not only are you extremely intelligent, but your voice is so captivating and alluring. You made this such an interesting and wonderful lesson. Thanks for the great video!
Yes
Yeah, he should do that relaxation/meditation type audio recordings, even the audio from this video could be used and sold as a relaxation yet educational recording
Plus he's pretty hot.
@@diem8638 bro he is 👌🏾
He's probably gonna meet some quirky cute girlfriend
"Rising like a Phoenix from the flames" Not gonna lie, a tear did roll down this cheek, this cheek made of star dust.
i was just randomly browsing trough videos about space and landed here and your way of speaking completely captivated my attention and i sat here trough the entire video feeling that i want to stay longer and know more, the way you speak and explain things made me feel like i really learned a lot. Thank you.
Your voice coupled with the instrumental is so calming. I opened the video with an intention to just see the opening minutes, but I ended up watching the entire video.. awesome stuff.
I'm not a big tea drinker, but the suggestion to "grab a cuppa tea and settle in" was so warm and inviting i simply couldn't resist.
*takes a sip and presses "play"
I don’t know how someone this talented in his craft doesn’t get more exposure
He does'nt need to say ooh look at me are'nt i clever .He just get on with it.
Unfortunately, most people would rather watch the Kardashians than learn about our universe.

You are so so sooo good at speaking, so knowledgeable on the subjects you cover and so incredibly talented when it comes to choosing background music for your videos. I just don’t know what to say other than - please, don’t ever EVER stop making content. 🙏🏻😊
As long as the sky is clear, I still go out several times a night to check on Betelgeuse. Thank you, Prof Kipping, for yet another superb video.
Professor Kipping, you sir are amazing. I can't even begin to describe or explain the knowledge, wonder, feelings, and emotions you instill in me with your videos.
I suffer from sever eyesight issues and am unable to see stars with my naked eye. When i go outside and look up, all i see is a sky filled with an inky blackness devoid of light. My only hope for seeing anything in the knight sky is a good clear sky and a bright moon, the only object I am able to see in the night sky.
So of course, i passionately yearn for knowledge and visuals of the night sky, and with your channel and mind blowing videos, you not only bring me knowledge and great visuals, but also deep emotions with your commentary, I cannot even begin to thank you enough. Thank You so much, not only for your videos, but the thought and meaning you place in them with high regard to your final thoughtful statements.
Thank You, so, so, very much.
Robert Ditto That’s wonderful to hear - astronomy is so much more than what can see directly, it deeply connects to who we are and where we all come from.
The Sun is 8 light minutes away from Earth which is 1 Solar distance away. If the Sun were 1 light year away from us it would then be 65,000 solar distances away than currently. If the Sun were 640 light years away ( as in Betelgeuse's case) the our Sun would be 41,600,000 times further away than it is currently. Would we be able to see out Sun then? No, and not even (in my opinion) if it were 1400 times larger as is the case with Betelgeuse. So how can we see Betelgeuse with the naked eye? Please try to ponder these proportions and distances. The brightness difference is no real consideration to make up the discrepancy, here. Please consider that I know only what I found on the internet with respect to distances, sizes, etc of this star. Also, I know very little about such things. However, I cannot see a way to visualize this star with the naked eye if I am even remotely close. Thanks for indulging my ramblings. Keep safe, folks.
@@cuttheknot4781 The furthest star we can see with our naked eye is about 4000 light years away, thats. 6-7times further away than Betelgeuse. Obviously size makes a difference, but its not really a matter of opinion whether a star is visible, its just physics and maths. If you look up into the sky in perfect conditions, you will see about 2000 stars with the naked eye. Considering we can see 4000 light years, some will lie further than 600 light years.
@@cuttheknot4781 We can see very distant, bright stars at night... When the sun is on the other side of the planet and there's no other light to drown it out. Consider how bright the sun would be, even a hundred million times farther away than it is now, when it's compared to a background of absolute darkness. That's why you can see stars.
@@cuttheknot4781 - great logic but unfortunately a flawed one. It is not just the distance, it is the brightness also.
This was great! I’m an amateur astronomer and star gazer, devouring whatever I can find on the subject for most of my adult life. I learned many new things in this video, so thanks so much for sharing with us.
I admit that I’m sort of disappointed that it likely won’t go supernova anytime soon. It would be such an important moment in modern human history. So many people have never really taken the time to look at the night sky. So many people lack amy appreciation for the universe we live in. It would almost certainly rekindle interest, and perhaps help people begin to realize that the light pollution we subject ourselves to is not only not healthy for our circadian rhythm, but also stunts our natural curiosity and desire to explore and learn.
I think i learn the most from your videos compared to any other. You put in so much into these I appreciate you sir! Plus your voice is very soothing and clear to understand
Just wow. Literally have goosebumps. Amazing video, amazing work and amazing everything. You explain this with unbelievable calmness and love for what you doing. Thank you. really amazing.
I recently had a dream that Betelgeuse exploded while I was walking down the street. It suddenly lit up the night sky between some buildings, and everyone around me started panicking. It felt so real, I was so excited. Then I woke up... lol. 🤩

Great videos, very informative and really well edited. Love the music and the graphics you have used.
You are an eloquent narrator… And your enthusiasm Is conveyed beautifully… Thanks for another wonderful piece!
"You are, in essence, made of ash."
Puts the entire "Ashes to ashes. Dust to dust." thing into a new light.
It is both humbling and exalting. We're made of dust, sure, but it's star dust.
Whaaaaaaaaaaaaaaahot!!!!?
We're made of star dust. That's poetry and science
@@rocioaguilera3613 that's a fairytale!... Not science!
Ashes was added much later to fill out the burial service. Earth to earth is more correct. No profound revelation in genesis...if the bible mentioned the heavier elements like the iron in our blood I would be astounded but to state the obvious hardly makes the grade. Lovely prose however.
Science communication at it’s best: informative, poetic and inspirational. Thanks for all the hard work you put into these videos!
This guy is great. He doesn't try to act goofy or give some political bs. He just gives the info based on non biased research. Its refreshing to be able to watch something that is political free ya know? Pretty soon, space will be racist, sexist, homophobic etc etc.
Also calming and musical, like a lullaby. Well, it's had that effect. Awwwhhhh. Tiring but not boring.

As a university professor myself (mechanical engineering) I can only say thank you for sharing your inspirational knowledge!
I must say this was brilliantly put together. As most have said the philosophy science and oneness you help explain is just what we needed. Thank you for your expression. Love and light
Oh god, I almost cried at the end. I don't know why, but I love our history, and the stars, and the fact that we originate from such incredible and beautiful things. That what we look out at in the clear sky on a dark night, is what makes us up and is part of this giant cycle of life.
It's fascinating and beautiful, so thank you for putting it into such nice words in this video
Lol I did cry! Omg what he spoke of is one of the most brilliant n beautiful things I've ever heard. Its intense
Thanks be to God for such an amazing cosmos and our beautiful, material origins.
I only wish we knew more. I WISH we could know the birth and death of stars. Been inside of one even.
“We are star stuff which has taken its destiny into its own hands. We are a way for the universe to know itself.”

This is amazing, I got into star gazing and trying to name all the stars a couple years ago, and I noticed this myself when Betelgeuse got dim, I had a hard time recognizing them, glad I finally found out I wasn’t going crazy
I hear ya bud. I was in the same boat as you.
how much fuel oil does that star burn in gallons per day!
@@jlo13800A star doesnt “burn” fuel. It is a massive ball of hot plasma doing nuclear fusion in its core, fusing hydrogen to helium and more
Its a plasma spherical 2 stroke that taps ZPE aetheric energy. fustion is just a side order effect.
Between the subtle background music and this guy’s voice, I’m being lulled to sleep. I’m saving this video for nights when I have trouble sleeping.
This video was so absorbing and well done that I immediately subscribed.

Listen to his speech at the end of the time travel video if you haven't already. It's mixing science with sheer poetry.
Maybe we need a new word for such a really moving speech. A peach of a speech. A *speach*.
So true! I am still wiping my tears.
Do you guys take estrogen?
I just love the way David's explanations make me feel a little less dumb. Great job.Thanks.😊
The unbelievable video power you and your voice have is…. Just something else. I can’t help but watch your videos for so many reasons. Most of all, science.
Thank you Cool Worlds. I often get caught up in the struggles of life, making me feel like life is pointless and meaningless. Its nice to be reminded of what we are and where we come from and that my insignificant life is part of a much bigger story.
Well, I guess that wipes out one of the items on my bucket list: to be around when Betelgeuse goes bang and to be able to see Andromeda clearly in the night sky. Ah, Shucks!
You can actually see andromeda in the night sky if it’s clear enough look at some videos
Me too!
What a masterful narration, particularly the warm conclusion. Im glad i discovered this channel
Fantastic explanation and great graphics supporting the understanding! Really superb job, Sir!

Yes the cow is insane. I think she is becoming quite famous these days.

Too big right?
I watch A LOT of astronomy related stuff, but the overall professional look of the videos and especially your narration makes this channel my favorite. Thank you!
The idea of an entire star just "winking" out of existence is so mind blowing.
I enjoy just listening to these videos as much as I enjoy watching them, kicking back with a cuppa or something and just chill, the beauty of knowledge and learning....
Keep up the phenomenal work! 👍🏻🍻
Apologies, but I'm going to need more information about that gigantic cow. What a beautifully immense creature.
Haha I know, that’s why I *had* to find someway to include this cow in one of my videos
think it was the worlds largest cow, somewhere in aus if i recall correctly :P
@@SamWilson Thank you :)
Forget about Betelgeuse. What would happen to this gigantic cow; 🤔
A core collapsing supernova or imploding into a black whole 😂
Just imagine standing next to that thing. I was like holy crap!! Lol
If only you could hear my standing ovation. Well Done!
I hear you and much thanks!
But seriously, this is a great presentation, and especially since it doesn't dumb down the content or use a presentation aimed at teens and twenty-somethings with attention spans degraded by social media.
came for Re:zero
and stayed for the science
I'm Betelgeuse
same lol
Im actually mid way through watching re zero and i love it
I love my rem

Cool Worlds has quickly become one of my favourite places to learn about our universe. Thank you!
Man, I love your channel. You make everything so easy to understand. Thank you.
Such a magical presentation, and no drama! Thank you professor.
I love watching your videos. You succeed like no one else in explaining a complicated topic in an understandable and interesting way. Thank you for that...
Thanks x23!
The music you choose in your videos are incredible! Seriously, this is the one thing almost all people on UA-cam forget. Great job, I am completely hooked on your videos 🤘
Very applicable music but it is too loud to hear you speak clearly. I do have tinnitus which make hearing more difficult for me.
Can't believe I came across this channel only 2 days ago.. Thank you very much, David!
You have an excellent voice, measured speech, and thoughtful way of presenting. A good teacher. Much appreciated.
Beautifully described and articulated, David. My hat’s off to you once again. I see that you got into the implosion model for black hole formation vs. hypernova/grb model. There seem to be multiple ways to make black holes 🙂. Once again, a superb job.
I love the style of this video, great host! Good balance of narration and then graphic breaks. Thanks for not being commercialized like so many are today, this was a breath of fresh air. You had my attention the whole time, and very thorough but didnt lose me. Sub’d.
Your explanations are not just informative and entertaining to watch they are like poetry. Loved your content 👍
This is the first 30 min video I've watched on UA-cam. Great logic, material and observations. Kuddos
Some of the best content on UA-cam, in my opinion. Always thoughtful and thought provoking.
Agreed. I absolutely gobble this sort of content up, and I can say from fairly extensive experience that this channel is PARTICULARLY good... and I've only watched a few videos. Very glad I found it, and also very sad I didn't find it a long time ago.
I could listen and learn from Professor Kipping all day long, what a fantastic channel, thank you.
Fascinating and soothing while painting a swarm of block holes with a federation starship observing it.
Lovely video. You can get quite emotional listening to this fantastic dialogue coupled with these graphics.

Haaaaa, I get you...

Tord Indeed Joker it’s looking cool 😎

I absolutely love Cool Worlds. Just when i thought i knew every thing about a subject they go off and teach me a whole new angle and new perspective and best of all more information about that subject. Thank you so much to the teacher and students of this class!
Completely agree! Best up-to-date content about space i have found on youtube so far :) if you (the watchers) have any other sources of information / channels about the same topic, I'd be so glad to check it out!!
Greetings from germany🙃
I agree. It answered almost every question I had about stars in its class. The only things I still haven't learned are the star's past spectrum and its various sizes as it evolved into its current form. I think this is a realm in which channels like this one could really set themselves apart, with the proper presentation.
Me too
Andrew Cary sr thanks! I personally really get a kick out of going deep into a topic, beyond the headlines. We rarely chase the news cycle because it’s too reactive to go in depth usually, but this case tied nicely into some fundamentals about massive stars that is often omitted
@@CoolWorldsLab im glad when people that don't usually pay attention to these type of subjects are paying attention but i do get frustrated when people read a headline and all of the sudden know everything to do with that headline and then you guys make me take a look at my self and say you thought you knew it all but hears some more info. So like i said your insight is very much appreciated. Thank you.👏✊
Really like your ideas that Translate inyou're episode.❤ great work!
Excellent way of simplifying the most complicated phenomena of the cosmos, and making it possible for almost everyone to understand, thanks indeed
Love this guys channel and content. It's free of political correctness and politics in general. He doesn't try so hard to be "goofy" and "funny". Doesnt make click bait videos. He makes informative and easy to understand videos. So happy I found this channel! Keep pumping out this great content!
Yes! Couldn’t agree more.
Free of political correctness and poitics. Hmm yeah its a channel about space, astronomy and astrobiology. Are are you thinking of Professors making jokes about the political situation in the USA?
@@dan43544911 that's still possible tho
Channel is taking off, im thankful for your time making good content.
You are appreciated Prof. Kipping
Tell me... How great is Prof. Kipping?
And no matter what the subject, he ends the episode with sheer poetry.
A true Renaissance man.
You’ve a solid vernacular, and thats not often said from me, your vids are often an easy listen, and really keeps me informed. Thnx
I love this channel!
I was re-re-re-re-rewatching the Cosmos series by Dr. Sagan when UA-cam recommended your videos to me. And I am so glad it did! This is good stuff! Thank you!
@Froggy Blunderbutt Rogers, Sagan, Ross - Heart, Mind, Soul.
That phoenix-metaphor in the end was so beautiful, well done!
I'm glad I found this video. I've spent a great many nights lecturing my friends about red star in the Orion Constellation. Thank you for this
Superb, Fascinating !!! Love the summation at end !!!
The mass of beetlejuice is 300-400 lbs, he’s stated this many times.
God damn I need to lose some weight
@@mattrg1111111 wow... so youre literally the size of Jupiter's orbit in sun weight 🤔
@FaTe_AssasinZ FaZe ur telling me humans cant be 300 400 lbs lol i was joking anyways
@@Wyonite Damn, some people weight more than the sun, thats insane.
Zwölf Zwei Zwiebeln bro it’s a joke cos there’s a guy called beetlejuice n he’s 300-400 lbs
I love how everything links up together in the ending, like how stars are connected to us.
I could watch this over and over. You’re an amazing teacher! Well done! Subscribed.
Brilliant stuff, #CoolWorlds! Love your videos!
That was such a beautiful conclusion to an explanation of a complex and well thought out analysis. We are all star dust 🌟✨❤
The beauty of space captured in all of your videos and powerful words is truly an inspiration.
Great video. Well put together, well narrated, informative and entertaining.
Beautiful. You gave me the taste for the advanced. Your voice, impecable diction spiced with poetry and so much passion for knowledge and truth caught my attention to the very end and left my soul longing for more.
Absolutely phenomenal. Good work my man. Beautiful explanation and so in depth
