Several thousand light years away from the Sun there is a fiery inferno. The surface of a small star is so scorching-hot that its heat reduces any celestial bodies in the neighbouring parts of space to ashes. It is burning so furiously that it barely remains in its shape. This object is about to explode, and the blast is going to produce an incredibly powerful flare. We know just a few suchlike objects. Unique and dangerous, WR 102 is the hottest star in the universe.

Thanks so much for posting this & all your really interesting, well-researched & expertly explained science stuff. This video, like all your others, has given me a smorgasbord of fascinating ideas to masticate, digest, ruminate, assimilate & speculate. Keep safe & healthy & God bless 🧔
Thanks for the video and data for the new class of stars as well as astronomy. Your work is highly appreciated man.
The ultimate Shikadov thruster. 😎
Excellent video! Having just finished Project Hail Mary by Andy Weir, I couldn't help but think of _astrophage_ and what it could do with a super-hot star (assuming there is a source of CO2 in the star system, which seems kind of unlikely, but still fun to speculate about)!
Hahaha
I'm 70 years old and a supernova visible to the naked eye would be a gift from the Universe! Go Betelgeuse!
I'm afraid it will take some thousand if not millions of years for it to finally go into a supernova
@@lost2weeks245 Actually, it could go supernova anytime within the next 100,000 years.
In heaven?
It would definitely be something! Think if it did it during the summer time if you are in the northern hemisphere. You could look up and see it during the day time.
Betelgeuse is approximately 650 light years away. If it goes supernova today, you won't see it until 650 years later, the year 2670. Hope you live that long.
Fun fact: there is at least one Wolf-Rayet star easily visible at night.
Gamma Velorum is a quadruple star system in the constellation of Vela, and one of the components is a WC8 star. The system is approximately 1,200 light years from Earth.
There is also another Wolf-Rayet star visible to the naked eye named Theta Muscae, also in the southern celestial hemisphere, although it is way fainter than Gamma2 Velorum, just barely visible to the naked eye in a dark sky area. Like WR 102, it is also notably a very hot star, estimated to be over 80,000 Kelvin. It is also a multiple star system, like Gamma2 Velorum.
That Frostpunk Music. Unexpected. Fitting, but unexpected.
Oh, I thought it sounded familiar! :v
I WAS JUST ABOUT TO SAY!
Thank you for making videos better than anything I had growing up.
Yeah it's a great video and you are a beautiful lady oh well I got something out of it I don't never get nothing no other way so I'll do it this way

@@RedOctober_ yup never assume the pic is real
I'm an astrophysicist and I just wanted to clear up a few things that I think you misunderstood in the video:
•Lighter stars actually burn LONGER than heavier stars. It's true that the amount of fuel they have available increases as they get larger, but they also burn it FASTER. WAY faster as a matter of fact. It's sort of like how a Humvee holds more total gas than a Coup but it burns it so fast that it will run out sooner. Also small stars are fully CONVECTIVE, so ALL of the star's mass gets cycled into the core to get burned as fuel. Larger stars don't do this as the layer above the core is fully RADIATIVE, i.e. gas can't sink below it, only light comes out of it. Imagine turning on the AC at your house without turning on the vent fan to actually push it through the vents. Same idea.
•stars that go supernova (those that are >8 times the mass of the sun) don't become white dwarves, they either become Neutron Stars or Black Holes. Stars smaller than that will become white dwarves but they never go supernova. The layers above the core just sort of keep expanding and expanding until all that's left is the core, which is a white dwarf.
•Stars don't undergo chemical reactions in their cores, they undergo nuclear reactions. Chemical reactions involve bonds between electrons that are bound to atomic nuclei, but there are no electrons bound to nuclei in the core. It's so hot that all the nuclei and electrons are free from each other. Nuclear reactions are things like protons and neutrons binding to each other in the nucleus. They are MILLIONS of times more energetic than chemical bonds.
watching this video I have noticed these things too. Riddled with inaccuracies and mistakes
It's just desperate greedy morons who know nothing making videos with fake voices on topics theyre clueless about to get ad money. Block them from your feed
Yeah, unfortunately this is not the first of their videos riddled with inaccuracies. By the way, I was under the impression that a black hole can only form if the star remnant is greater than 5 solar masses, and typically a star with a solar mass greater than 20 is capable of leaving behind a remnant of 5 solar masses or greater.
Thank you Sergey, as usually great video, I been learning a lot through your tutorials. The narrative combined with the animation and the captivating graphics make easier to assimilate this type of information which would be boring to digest from books. Keep up with the good work.
Frostpunk music, very nice
you definitely uped your graphics game for this video
You like it? It's too "americanish" for my taste, too few facts, too much key jingling
@@pixelsafoison You really should not expect a lot of facts on a star that we barely understand yet.
RTX on?
@@bujfvjg7222 now that's just mean, you know full well that no one can get his hands on a good graphics card at MSRP and yet here you are.... You sir have reached a whole new level of cruelty.
Considering that 94 % of the universe is moving away from us so quickly that we will never be able to actually visit.....it is quite a thing to say this is the "hottest star on the universe "!!
Yes. Such inaccurate descriptions make me not to take channels like Kosmo serious.
@@data1.078 or you can use your brain and think that it’s the hottest star in the observable universe that we have found.
Hottest in the observable universe. Not the hottest. Nobody knows that!!!!!
@@kingley45 Maybe not be a twat next time pointing that out?
It's a good thing that all we see in the universe is in the past. Can you imagine the panic if we got our measurement wrong of what is a safe distance from those super hot stars that have already gone BOOOM!
I've been watching Anton Petrov, John Michael Godier, Astrum, SpaceRip, and SEA for several years and this channel has NEVER been recommended to me. How on Earth did I not know about this flippin' channel?! RUclips, you failed me hard on this one.
Watch your profanity
Try the channel What if, they produces good vids about cosmos also.
@@absolutedoruiyaaa4736 Couldn't help it. Was way too excited.
I really don’t recommend this channel because of all the misinformation in this video.
@@ark8tct Thanks for the recommendation, ARK! Appreciate it, bud. Yeah, if any other astronomy geeks like myself are out there and haven't had a chance to check out the channels I've listed in my OP, please do so! They provide some top-notch content!
Furthermore, if anybody knows any channels that aren't on my list... and probably should be... please, let me know so I can add them! Thanks all!
Da real miss universe, since she’s the hottest star🔥🥵
No, that’s Miss Philippines 🇵🇭 💫
But not that bright?
no miss south Africa (lol)
@@lightscore96 i prefer miss joe
@@lightscore96 alas she clapped
2:12 Not sure if a Main Sequence star like our sun star goes supernova after the Red Giant phase. I think it expands, sheds its outer layers and becomes a white dwarf. A massive star that goes supernova will collapse inward on itself because it does not have any more fuel.
This is breath taking! 👌🏼
This is an outstanding doc on the most blazing-hot star in the universe that's packed with incredible animation & brilliant narration 😍👍👌
Hottest star that we know of in the universe*
Fixed that for you. I hate it when people speak in absolutes as if we know for sure that it's the hottest star in the entire universe, which contains at the very least, trillions of stars, is right here, in our own galaxy. It's like when people say that Stephenson 2-18 is the largest star in the entire universe or that TON 618 is the largest blackhole in the entire universe.

I really like how you say your "Os" it's cool! Best space channel on here!
I don't want to be "that person" but the hottest star in the *observable* universe would be more fitting
LOL, I'm glad that you were that person so that I didn't have to be
They don’t even know for sure that it’s the hottest star in the observable universe
Also..... If it goes supernova it won't leave behind a white dwarf.
Marry me
"Observable universe" has nothing to do with our capacity of observation. Check for the correct definition.
Man... I Gotta admit such visually beautiful clips in this video. I wanna make HD wallpaper out of it to set on my phone. 😍😍😍😍
Cool! Wolf-Rayet stars have fascinated me for quite some time
fyi, all WRs will become black holes because their initial mass is very high
Still not as hot as the blast from my oven door when I check the pizza 🥵🔥
😵 😲
😁 😂 😃 😄 😅
Best of. Tying WR objects to the simple circle of life in our cosmos. Repost. Update? You have done a fine job.
You said @2:01 that the lighter the star, the less time it will continue to burn. That is not correct as the heavier stars live shorter lives than lighter ones. Also @2:10 you said that the star sheds its outer layers and goes supernova, leaving a white dwarf. This is incorrect as white dwarves are the remnant of smaller star incapable of a supernova. Supernova remnants are either neutron stars or black holes.
It's someone using a bot as a voice, what did you expect?
Also, in order for it to become a *neutron star*, if it actually had 40 times the mass of our sun, it would have to shed roughly 90% of its matter before it ex/implodes, because only then the mass is low enough for that outcome. Everything that leaves a higher mass, would rather turn it into a stellar black hole. The Wikipedia entry however estimates that it is currently as heavy as twenty suns, which means it might already have lost at least half of its initial mass. They also have a pretty infrared picture of the star.

I wonder if that's where alien's go for a holiday
Imagine if aliens out there feeding on pulsar star radiation 😳
@@ardi08 dyson sphere check it out

Excellent video! Well done guys! Keep it up!
These visualizations are outstanding.
The thumbnail agrees with the Wein's Displacement law according to which, the highest temperature (hottest star) should have the shortest wavelength (violet). Nice.
A small error 1:23 not chemical, Nuclear Reaction.
Great video ❤️
Beautiful footage 🙏🙏🙏❤️❤️❤️❤️
Great and interesting video. Thanks a lot for posting...
Superb video, fascinating. Thank you 👏🏻👍🏻
Super quality upload as always 👌👌👌
I'm not a specialist. But I think white dwarfs don't come from stars going super nova. Very nice post, thanks.
You indeed are correct, my fellow astronomy friend.
@@MrEnjoivolcom1 Thank you. 😊
@@zeom76 you're absolutely incorrect
Amazing video. Excellent work!
@2:05 - Fyi...a white dwarf is not the product of a supernova. White dwarves can be the progenitors of type 1a supernovae if in a close binary system and accretes enough mass to exceed the chandrasekhar limit.
Another gem! Thankyou kosmo
Hmm… Wulf Rayet Stars. They have a short term red super giant phase mainly being a variable star. They usually produce magnetars or black holes because of the sheer mass alone. They mainly have a small iron core.
Nice vid. Thanks!!!
So THIS is the supernova we are most likely to see!
Nice!
Lets go I caught it in the first hour I absolutely love these docs
Which docs?
Most amazing space animation I’ve ever seen ... deserves an Oscar
🤩
Oscars don't mean squat. I don't want see the Cameramen knew to the Hollywood mov for a shammy award.
Great video and amazing graphics!
Subscribed to this channel utterly fascinating... Thanks 👍
Hello to you. When I saw the the description for this one I thought to myself ( Hello I better get the Sun factor and Shades ready.) However I very quickly realised That Basking in the noon day Sun would be a very bad Idea. 200.000 Degrees Hotter is just Staggering!!! needless to say I won't be going on vacation to WR 102 any time soon. Fantastic Video though. : )
Good stuff man i subscribed few months ago
And you all know that from looking at a beam of light millions of miles away...?
"Hottest star in the universe"? or just hottest star measured so far?
I'll sub. Out of all the similar channels I fw this already
Kosmo the best I don't miss any of them
Great video! Great channel!🙏
Yo shoutout to the cameraman.
Superb presentation 👍
When heat isn't even heat anymore...laws of physics breaks down.
If the temperature of the surface of this star is ~200,000 K, then it's corona would be absolutely insane, and that's probably the understatement of the year.
Its still the corrona what if the core
Found a channel to binge for the month
@Jackie Price oh totally
It's kinda weird to observe and collect data from a star that may have already died in a supernova blast. We can always observe the past when it comes to the cosmo.
"chill TF out bruh"
"Nah"
Nice frostpunk music in the background
So we really out there traveling in alien ships learning this ish?
0:00-0:15 is just a description of Arizona
Wikipedia says that WR102 is only 16 solar masses. There also appears to be a nebula forming prior to the star going supernova.
WOW powerful stuff please keep on making new videos
Love the frostpunk theme. 11 bit ftw!
My brain loses the concept after a kajillion degrees Kelvin. ✌
My brain can handle up to around kajillion and three... then it goes super nova and dies off as a red dwarf.
@@chickey333 Hey, you are three up on me Chickey!
Actually I don't know just how many a kajillion really is but I figure it's a number that starts with a one and ends with a whole bunch of zeros. I'm guessing the scientists who try calculating the size of the universe would admit the same thing.
In an endless universe they have somehow already found the hottest star. Crazy, what are the odds of 1 in infinity.
Very good
*Gee camera man is immortal*
Main sequence stars do not go supernova after expanding into a red giant.. The simply die off quietly, shedding their shells of gases, leaving behind the white dwarf core.. Cosmologist's say they "die in a wimper.. Not a bang"
Excellent video, either wat!!.. You have a new subscriber in me!! :)

The circle of (cosmological) life.
Wait until its final evolution with ultra Instinct.
Goku should start training on the surface of a neutron star
The mashed potatoes I'm eating are probably as rare as that star.
So that's why everyday is very hot, a giant star near to our solar system is very hot all day.
There's always Eta Carinae, ready to go at any moment.
nothing hotter than my burger that was inside 1 Hour and 30 mins in a microwave
"The surface of a small sty...
Wolf-Rayet objects are fascinating.
2:11 - actually, stars that are this light don't go supernova. You need at least 8 solar masses for that, and a supernova leaves behind a neutron star or a black hole.
I had no idea that a white dwarf could be the result of a supernova
Very good 👍👍🙏🙏
Metal slide: allow me to introduce myself😊
Wait, I thought a super nova does not produce a white dwarf. I though a supernova destroys everything, unless the star is a certain size where it then creates a neutron star. I thought to get a white dwarf a planetary nebula was created, so no explosion.
Stars like our sun not big enough to go super nova will end its post life as white dwarf . yes he got a mistake. After supernova u cAn have a nutron star magnetar or more than likely a blk hole .. But not a white dwarf
Insane !!!!!!!!!
Another possibility is production electron and positron forming matter and antimatter formation and merger producing very highly energies as part of the fusion.
Best scientific chanell in you tube god bless you we've love you from great IRAN
One huge error. A supernova does not create a White Dwarf, a supernova create Neutron Stars.
It can create White dwarfs, neutron stars and black holes. You’re welcome friend 😊 depending on its Mass before going supernova
Neat. I don't hear a lot about Wold Rayet stars
Hottest star in the observable universe*
Astronomical distances fascinate me. Looking out into the universe we do not see what is, we see what was. To me, it gives a new definition to the word “is”. (Maybe Bill Clinton was right after all: It depends on your definition of “is”.)
No star in the universe is as fiery as WR 102!! That's unbelievable 😮🔥
Do i hear FrostPunk music?? You sir, you have good taste.
😩 “ OH WELL!…. What d’ya do? ”
This is summer for the universe.
Wolf-Rayets are seriously bad news ( for unfortunate locals). BLAMMO! ✨
yo what the hell you guys deserve a million subs and not 100 k, keep going ur amazing
There’s a bunch of misinformation in this video tho.
Was the Frostpunk soundtrack used for ambiance or cheekiness?
can you imagine how bright it would be if that start exploded a single light year away
We would die before we could see it, well not actually but a 1 year difference would not really matter for humanity lol
This reminds me of the time I accidentally turned the oven up to 210000 degrees Kelvin.....what a mess....that food was terrible
The frostpunk music theme is distracting me 😂
