The New Largest Star in the Universe 2024! WOH G64
HTML-код
- Опубликовано: 22 май 2024
- For many years UY Scuti was considered the largest known star in the universe. Then came along the behemoth that is Stephenson 2-18. But it turns out that measuring enormous, distant, bright stars isn't easy, and both UY Scuti and Stephenson 2-18, although very big, are probably not as big as initially thought. So by using the best measurements available, what is the current largest star in the known universe?

I watched size comparisons when I was 3 and Im 11 now...
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever
The more we know about universe. The more we know we don't know
so deep
Madness unimaginable possibilities, I would love to live for ever, just to get a chance at space travel .
@@richkavanagh2778you'd lose your sanity eventually.
Its the one un solvable question. What do we NOT know...😊
Yea I know right
Petition to rename it to "WOAH" instead of just "WOH" tho? I mean, it's asking for it
That's a shout
Petition to rename it to “comically large star”
Starry McStarface
We need someone with the initial “a” to be credited with discovering it. After all, it’s already named Westerlund-Olander-Hedin
@@cadmus204yes
"Bettel--goose" just sounds wrong
It is wrong. Threw me so much that idk if that was even the star he meant now lol
😂😂
😂
English English. what are they thinking? are drugs involved?
@@egay86292 I've never heard an English person say it like that until now, and I live there
You were right to point out that the exact size of some of these huge stars can be very hard to measure. Red giant atmospheres seem to have a more diffuse edge than that of say, the Sun, or Sirius. If you look at photos of Betelgeuse, you can see redder and yellower areas, and a diffuse edge. That's right, the disc of Betelgwuse has been imaged. It is no longer merely a single point.
There’s also the fact that they’re not perfectly spherical. They’re more like big puffy clouds of nuclear inferno that gravity is just barely holding together.
Yes, we don't have a ruler big enough to measure them! 😆
true! @@oberonpanopticon
@@Peekaboo-Kitty we should try a measuring tape, which usually are longer than rulers 😁

Maybe if we can line up all the Cats in a Row?
Entertaining and informative. Well put visuals, background sounds and the narration makes it really enjoyable to watch. Thanks for uploading the video, and keep them coming!
Ah yes, everyone's favorite star betelguz.
Edit: 100 likes! Thank you guys so much!
yup one of my favorite stars
Betel curse.
Why the flip do people doing these videos decide to change the way words are pronounced.
It’s like the rick and Morty episode. Parmesan- come on!
Bet tell Guz - I want to slap this person

And this new biggest star could still be minuscule compared to stars we haven’t discovered yet. Our universe never ceases to amaze and remind us how tiny and insignificant we are in comparison
Nice profile pic dad! ❤
That is true. One paper suggests stars outside our Galaxy can grow to up to 2600 solar radii!
I don't think we are tiny or insignificant. But I think that we think there are things that are tiny and insignificant. And we would be wrong.
@@Scuti2It’s possible that stars in the very early/distant universe could’ve been a decent fraction of a light year in radius.
Look up Kurgezgat Black hole stars. Youll sh¡t yourself.. i did.. makes my heart sink thinking that theres ultra massive stars that dwarf these bigger stars in this video. Potentially explaining how supermassive black holes got so big so fast.
Been waiting for a video...
It's snowing here, 4 inches already.. perfect for a v101 video..💙💙👍👌
I am glad you gave the proper definition of what Mass and Volume is. TV shows often get them wrong. As for the video great as usual. It is the next best thing to actually being there.
How dumb do you have to be to give the wrong definition of mass and volume? And since when do TV shows bother to give the definitions of these?
On T.V. (and in reality as well) people might use massive and giant interchangeably, but that's not really wrong, since both are opinions, not to mention mass and volume are positively correlated.
bro he isnt dumb so shut up@@AnonymOus-ss9jj
Love your videos! Nothing is more interesting than our universe and the origins of time
Another great video as always Rob
I love these vids. A few years ago, I saw a video saying the largest star (volume, I think) was VY Canis Majoris. One specific fact stuck: if you take an airliner to fly around its equator, it would take 1100 years!
Back in my day Canis Majoris was all the rage
Stephenson 2-18 is #1.
@@darkhumor39 🫣he means far..FAR before they discover the stephenson star..
Same back in my Day u scuti was the largest
atleast it has a name?
I remember those days! VY Canis Majoris ftw!
I love your videos, especially about star comparisons. Awesome !
Love your videos.
Thanks
Stephenson 2-18 took the title of the largest star known from the previous record holders, the red supergiants WOH G64 in the constellation Dorado and UY Scuti in Scutum. WOH G64 has an estimated radius between 1,540 and 1,730 solar radii, which is considerably smaller than St2-18.
St2-18's radius involves pure assumption of its surroundings and a very uncertain distance.
WOH G64 has a estimated size that is between 1,540 and 2,575 solar radii. just looked it up.
@@StaticDaSticc 1540 Rsol is currently the best estimate out there.
ST2-18 Is 2150 solar radii!
@@sebastiansgalaxy4810 That estimate is highly inaccurate.
The scale we are talking about is really astonishing. It always surprises me.
Excellent Video, as always, Thanks Rob & Crew @ V-101 Space. 👍
Crazy huge stars and space objects in general, never boring.
thanks for the reality check on information we see about star size. cheers
Creative as usual 👍❤
Always enjoy your vids ❤
Simply amazing! Thanks for the video!
A excelent video! Much apprecated Rob Cheers from Canada!
I love how some people and robots say "Betelgeuse". I understand that it could be hard to figure out if you've never heard it said before, but you would think a video from a creator called "V101 Space" would get it right.
Lmfao you can't force AI voiceovers to do correct pronunciations - they're not open ended LLM
Is this an AI voice over?
@@astralgames5535 Yes, the voice is very lifeless.
The world 'Betelgeuse' is derived from Arabic word 'ابط الجوزا' which means 'black and white sheep's armpit' so is there a correct pronounciation for that?
Brilliant as usual, thank you!
Great video. Thanks.
One thing is clear. That we live in a universe of extremes.
On that note.....you and Rolo have an extremely stellar weekend. 🇺🇸❤🇬🇧
Thank you for not being a robot voice.
@@EmilyXiong1999 if you're talking about the video, it is a robot voice. Edit: just a more natural sounding one than many others
@@Fromatic Wow. It sounds much better than some human narrators. Some of those have speaking patterns that make me want to plug my ears.
@@EmilyXiong1999 yes, even though I can tell, I was still able to watch the video, the others I have to switch off immediately as they just grate on your ears
did he just call it "bettelgurse"
Fascinating! Our tools are getting better and so does our understanding.
Definitely one of my favorite channels on YT for the last couple of years!
It has been considered among the scientific community to be the largest since 2009, alongside VY Canis Majoris.
The human mind is incapable of comprehending the sheer scale of the universe. And while it is awesome to speculate we will never be able to comprehend these sizes. And yet we still continue to war and fight each other over the manager resources of an incomprehensibly small speck of dust. It is nothing short of the greatest miracle ever that we have managed to make it as long as we actually have.
It’s more of a testament to how stupendously hard it’d be for us to completely wipe ourselves out
Thanks a lot for such a beautiful video and explanation❤❤
Ooh i really like your voice. Another channel subscribed.
It’s not even there any longer. We can only see the light that has traveled gazillion light years to us.
I'm always surprised, how stable our Earth is, considering how tiny it compared to the other objects in the universe.
no shit, really?
oh that is just an illusion buddy ! you must understand that your lifetime, indeed the lifetime of human history, is not even the blink of an eye in the Earth's history, the Earth is absolutely evolving, it's just that we aren't around long enough to see it. Go watch Melody Sheep's video on the evolution of the universe, where the speed of time doubles every 5 seconds, then you'll see what's in store for earth...
Relatively speaking
oh well NOW you've done it.
Intelligent design bro.
Quite fascinating,i did enjoy the video...
I enjoyed it 👍😎 this is so interesting
Another exceptional video, Rob! It's absolutely mind-boggling how massive these stars can reach in size, and what's more incredible is that bigger ones are being discovered after what is thought to be impossible 🤯
Don't be boggled. They aren't massive, they aren't that far, and they are luminaries. NASA feeds you sheeple food, don't eat it and learn to think for yourself.
4:35 ... Behtle guhzz?
Thank you so much because this video amazed me 😊😊
Very enjoyable! Bravo
bettlegurrs? you mean betelgeuse.
I hope I live long enough to see a hyper giant, go hypernova (visible from the northern hemisphere).
What a spectacular sight that will be, whenever it does happen.
I mean, Betelgeuse MIGHT go off within this century if we’re incredibly lucky and it’s in its carbon burning stage.
2160p 4k visual, beautiful!
I watch the intro and I subscribed immediately
100 to 400 billion stars in our own galaxy? That's a 75% discrepancy. Someone get on this asap...
english bible saying "the world" and hebrew bible saying "the cosmos" is a 99.99% discrepency...... but when try to learn hebrew from ppl they say dont worry its the same ITS NOT!
100B stars in just the milky way and then when you think how many galaxies there are out there and then when you think that the universe that we know is 93B light years across.
Betelgooze? You mean Betelgeuse?
Excellent narration..
Thanks for the info 🖖👽
UY Scuti will always be in my heart
Definitely agreed
Amazing to think about the time it would take at light speed to circumnavigate these stellar giants! Fantastic video -- as you say they'll probably turn JWST on another point of light and discover an even bigger monster star before too long.
Cannot turn at c (lightspeed), you have to go straight, so circumnavigating a star is impossible.
Yep, it's a hypothetical circumnavigation anyway, as stated in the video.
BANTASATIC AND TRANTASTIC
Great content and presentation. 🇦🇺 😊
THANK YOU FOR MAKING THIS VIDEO!!
BAT 99-98 is at nearly the currently understood "maximum" mass for a star since any more mass would be blown away due intense solar wind. The only stars more massive are the theoretical "black hole stars"
There’s also some accreting object (I forget the name, sadly) with something like 1000 solar masses. But by the time it becomes a proper star most of that will be blasted away.
The star “bettle gus” hHahaha
The universe is huge it's just mind blowing and the more we know the more We don't know
Good stuff!
Bettlegurz??!!😆😆😆
Bettle-🤯
You MUST be kidding. 😂🤣😭
A real WOH moment
Most intriguing 🤔
That "hhhaaacchee" - H lol, really got me.
Hache🤪. I turned off
Awesome channel with awesome content as always say
Love watching these videos learning more bout our universe. Thank you for an informative documentary
Australia
Its so mind blowing when they show size comparisons of these massive stars next to our sun. And our sun, which itself is insanely HUGE, is absolutely DWARFED by it. I literally cant imagine an object being that big. Making our sun look like a grape, thats just insane. This is why when people say we're alone in the universe, I just stare at them dumbfounded. People just do NOT ever think about the sheer size of the universe. Its literally IMPOSSIBLE that we are the only life in it. Thats like an ant declaring ants are the only life on Earth. And the ant isnt even aware of Earth being any bigger than a street corner.
We're not the only life, but distance and time renders us effectively alone all the same.
Look up Kugezgat - black hole stars. If you rhink these stars are big. There are potentially stars that dwarf these super massive
Scientists won’t find proof of extraterrestrial life in anyones lifetime…
Thanks!
very watchable thanx
I've never heard of the star, Bettle Gurse @4:35, but I have heard of Antares. I'm surprised it wasn't pronounced "And Tears".
BETTLE GURSE PRFF
I farted today.
Stevenson 2-18 Wow 5:07 at the speed of light it would take 9 hours to complete one loop as compared to around the sun which 14.5 seconds.
Something about stars and planets outer space gives me a warm fuzzy beautiful feeling inside.
I knew it was only a matter of time. Now let's find the next one.
I really don't understand how there can be a limit to the size of a star. Say that 1500x the volume of our sun is a correct limit. Well, what happens if that star merges with another star? Wouldn't that result in a larger star?
Too much mass and it colapses into a blackhole. So I'm not sure what the answer is but there's a limit.
Well, there has to be some kind of limit to a star's growth. Otherwise, it would be possible for a star to become the size of the largest black hole and that isn't possible. Stars can only get so big before they either go supernova, become a black hole, turn into a neutron star, etc.
@@RazorbackPT Is that why every galaxy has a massive black hole in the center? It was an instant black hole and the star systems around it are from the remaining matter?
if the QUASI star theories are correct, then yes, what you said isn't wrong .@@zmbdog
Well, when it comes to mass, the limit is around 150 solar masses because of pressure. The more massive a star is, the more pressure there is in its core. The more pressure in the core of a star, the faster it fuses fuel. The faster it fuses fuel, the more energy it outputs. At a point, it’s outputting so much energy that it ends up blasting away any nearby matter that could’ve made it bigger.
The upper limits on radius are less well understood, but are probably related.
I told myself if this is one of those ai voice overs I’m skipping
Fantastic animation
Nevwr heard of this channel. Seen it by accident. Definetly goin to be here a while
Battlegers? 😄
ITS NOT BEKKELGOOSE AND NOT ANTERS ITS BEETLEGUSSE AND ANTARES
It’s not “its” it’s “it’s”
Magnífico vídeo e uma verdadeira e necessária aula de astronomia! Acompanho estes estudos sobre o Universo desde 1961 e de lá pra cá não me canso de aprender cada vez mais. Parabéns pelo belo e importante trabalho que realizas. Abraços fraternos do José desde Brasil, América do Sul.
Graham's number sure did impress me when I learned about it. I wouldn't have thought to name a star after that fact though.
It's better to say "aitch" than "haitch" for the letter H.
WOH: I'm the top Dawg now 😈
Stephenson: No way 😢
UY Scuti: First time?
VY Canis Majoris: 💀
A lot of these hypergiants are so "puffy" and diffuse they are almost more like overdense nebulae than they are typical stars.
thank you
Betelgrrrrss 🙊🙊
IM SERIOUS STOP MAKING THE STARS NAMES MISSPELLED ITS NOT UB SCOOTY ITS UY SCUTI
😂 he said bettlegurse
Good Video
I was with you until "Bettle guss." Lol
WOH, that's so cool! I'll see myself out now...
Bettel gers????
Universe:These tiny ants are arguing again.
VY CMa was once “the largest star in the universe” and, as of 2020, 2069 solar radii and second only to Stephenson 2-18. Stephenson 2-18 was estimated as being 2150 solar radii, but this was a very rough estimate. VY CMa was, however, backed by earlier estimates that consistently showed a radius greater than 2000 solar radii.
_"It is estimated that if all the material in the Taurus Cloud was collected it would be enough to make our entire solar system nine times over."_
That is one of those well-crafted sentences that immediately and successfully puts a very complex and astounding scenario into clear focus and understanding. Stellar, professional work as always, sir.
further proof of how insignificant we are
So, 9.01 solar masses.. honestly doesn’t seem like all that much as far as space goes.
Compare that to η Carinae, which ejected 30 solar masses back in 1848.
What is "bettlegus?"
Consider me as your fan from Phillipines God bless you
❤ Your Voice ❤
I thought the biggest star in the universe was Elvis.
I thought it was Michael Jackson 🤔
What we understand from this concepts...is that man have little to no idea about what is happening in the cosmos and what surrounds him. Thats why he must be humble and kindly-hearted.
F to pay respects to UY SCUTI 🫡
That is the first thing i found
