My science teacher showed us this. Supernovas are so cool! The class spent like 20 minutes just talking about supernovas.
Awesome! Now you'll have some sweet new facts to discuss :-)
TBH Supernova really is cool but scary at the same time..
@@heartcruz1440 a tragic and scary beauty, exactly like the entire universe
I think supernovas cool too!just saying that their kinda scary 😅
I love space and stars but this is the problem I am only 11 so I have no idea what you are saying most of the time
I like how at 3:30 the supermassive star is about to explode and the sun’s like “I’m outta here!” XD
Haha right? As badly as I would LOVE to witness a supernova, I must confess, I'd probably scram, like the Sun!
lmao
XD
ight imma hed out xD
I absolutely love your animation style and the way you narrate. This video should have a lot more views (even though there are some minor errors, but they don't lessen the super high quality.)
Thank you VERY much, what kind compliments! Thank you very much for your support.
Don’t u mean supernova quality
thank you for this video....learned a lot .......hope to see more in the future.....a video on blackhole would be nice though😊😊
Spinotaraptor make your own video then mate
Great job, loved it! Keep it up, bro, a like and a high five, man!

What's the song for 2:13?
I think it's beyond beautiful that the iron in my blood was once in a star
This explanation and animation is outstanding! I hope education like this becomes so accessible, schools become remote & diverse.
I found it funny how some of the stars had a day and night side
Have shadow.
They throw shadeeeeeeeee
I didn't watch the whole vid so I did the random reply :P
@Harry Evett hi i know you
But 'most of the stars it's supernova' ? Sir, most of the stars are red dwarfs. And they don't become supernova.
You forgot something, some huge stars go supernova when it generates iron in its core
He's also forgot about the best part Safer Sephiroth
When I see supernovas, I don't see the death of a star, I see it's beauty because it gives a colourful explosion
I just wanted to say it because that is how I see it
man this was an awesome video and the narration was on another level ....... I'll try to tell all the people I can and try to increase the viewership
So... what happens at 2:40 exactly?
The star runs out of Hydrogen, Helium, Oxygen and Carbon until it fuses it all to Iron which when fused does not create energy somehow, right?
Then all the mass crushes together under its own gravity without a repelling nuclear force pushing it all back out. But then why does it go Supernova and not just become a big ol' block of iron or sumthn?
Due to some quantum physics the collapsing core produces a huge amount of energy in the form of neutrinos that spit out from it. This blasts away a lot of the falling matter.
3:44 is that a reference to hypernovas, when the star collapses directly into a black hole?
Yes, in many cases, very large stars (tens of times more massive than our Sun) go through a wild core collapse, resulting in a swirling black hole left behind. And, these black holes, similar to neutron stars/pulsars can also emit powerful twin jets as they radiate material from their surrounding accretion disks. Sometimes, people even refer to these as "collapsars," instead!
Im pretty sure its a "nova" that makes white dwarfs like the death that will ocour to our sun. And "Supernova" gives birth to Black Holes.
Fantastic video. The visuals are incredibly engaging!
Stars are literally the embodiment of the quote "Do not go gentle into that good night. Rage, rage against the dying of the light."
I was hoping to know how powerful these explosions are but that was awesome ✨
This video was amazing, it went into detail and improved my understanding of a supernova. I learnt a lot. :)
The word you were looking for is *learned* :).
Also, I like your profile pic.
:)
I love the way u narrate your videos
Almost always? The overwhelming majority of stars are red dwarfs. Those dont produce a super nova
Yea
they create a planetary nebula
@@yuvrajguglani821 The mechanics behind red dwarf deaths can not be directly observed, because no red dwarfs have died in our universe. They more than likely do not expand into planetary nebulae, or even red giants for that matter. They might even just compress down into a white dwarfs quietly and calmly.
Wow this helped a lot with all the science I missed during covid thanks !
I will start calling my beloved ones supernovas coz its really beautiful
Excellent, thanks !!!
how does this video have just 150K this needs to have at least 15 mil nice man!
Really appreciate the great quality and content of the videos!
Cool edition bro
Your animation is really amazing...
Thank you brother for explaining 😊😀
Thanks for this video 💜💜💜💜
amzingly explained
Actually, less than 3% of all stars will end their existence as supernovas
quality video in a short time!!
Very good animation and very easy to understand.
Unfortunately, they (and dozens of programs like Nova) never actually explain what causes a supernova. It just explodes (for some UNEXPLAINED reason).
Great vid 👍
Excellent video
Sun: Haha I have no twin I cannot disappear and other stars will be gone hahaha
Stars: We will merge and create a sun to destroy I Maharaja
Sun: NASA!! HELP MEEEE
Finally understood a big part of! Thanks !
Still just don’t understand why there can be gravity in the middle of the planet and why it’s always located in the very middle
woahhh superNovas are so cool, like I am amazed knowing about them
this video is very helpful
Good video!!
Amazing info!!! 😍😍😍💯💯💜
Great video
Thanks for sharing....
I detect quality content, just keep telling more about space and u'll rise :)
the narrator was superb, as a suggestion, please add subtitle. thanks
Excellent information
It would be amazing to witness a supernova
you said that stars almost always die in supernovae. that however is incorrect.
no he didn't
Most quality content
Brilliant vid
I love space!!!

ur the first ff7 comment i saw here and thats what im looking for lol
@@ryerboi4196 Believe it or not, I did the same exact thing, I also looked for a FF7 comment here before I posted this comment, but I couldn't find one, so I made one myself! lol

Subbed!👌
Great! Thx
Every time a new star is born, hydrogen content is lost and replaced with helium.
Please do dark matter, I really like your videos and I understand them more then other videos, so please
Thank you, @LilpandaChild Cruz! Dark matter is some pretty fascinating stuff, isn't it?! We love it too! We will take this suggestion into consideration, thanks so much for the wonderful idea! In the meantime, we have written several articles about dark matter and dark energy, be sure to check them out!

@astronimate Thank you so much😃
Superb....
The part where it said “Here’s Johnny!” 😂
Hey, I'm here guys, nice to meet you
3:52 We do have a good idea about the ages and types of stars in our neighborhood. Stars that are already in the Red Giant phase, will be the first to go.
another awesome video !!!
I subscribed :)
We support you bro..
I think that we should teach stuffs like that from a very beginning ...so that people can have intrest in space and universe it's so cool but instead in India most of the people don't even know this🙄😑
There's a TV programme on now in the UK on the Discovery Science channel plus an hour, about the next supernova.
I don't think I'll ever truly understand the nuclear fusion part but I'll take your word for it
2 hydrogen atoms weigh more than the helium atom produced after fusion. This mass that seemingly disappeared turned into energy.
Explained even more simply, atoms, specifically protons, don't like being close to each other. They repel each other, unless it is very hot. Once it gets hot enough, the atoms move fast enough so by chance, they get close enough to the point a *significantly* stronger force takes over and they violently snap together.
Final Fantasy 7 brought me here.
Science taught me that Super Nova is an explosion of the star...
In FF7, it can destroy planets
Even after watching / reading a lot of sources, I still can't grasp my head around how a star work. I mean, if a star is stable when the nuclear fusion and gravity is in balance, what making the core do fusion reaction as the material inside should be pushed out by the said fusion reaction, and if gravity wins, why supernova happen when clearly the core doesn't have enough material to run fusion reaction?
Here to maybe learn about Sephiroth’s Supernova ability.
Great video!
Minor errors: 1st: the progenitors of type 1a are polar white dwarfs. It has nothing to do with the chandrasekhar limit.
2nd: AN Ursae Majoris B is close enough to cause harm in the form of an EMP (electromagnetic pulse). It will wipe out any unprotected electronics on or above Earth.
Prediction: before 2030 we will witness 2 nearby supernovae. The star Betelgeuse as a core collapse event and the aforementioned white dwarf as a type 1a.
I just subscribed to this channel.
Keep 'em coming!
Awesome video man . you really should have millions of views cuz you deserve it
Came here after aespa
same 😭😭😭
Su Su Su SuperNova!!!
😂 me toooooo❤✨
Aespa who 🙂?
I had a super Chevy Nova 396 513 possy duel 4 barrel 4 SPD duel exhaust 50 series rear tires 15 inch skinnys up front . Unstable as hell but crazy fun to drive .
At 4:00 , the supernove should be moving as the moon and Sun are. Although it is much further away the earth's rotation would still change its position in our perspective sky.
"You can never know for sure"
Me- "Alright listen here you little shit..."
wow, thats nice
One of the five mass extinctions in the past is believed to have been caused by a near Earth supernova
make it sound hard the first min, gj dude
I put this full volume and my house exploded at 2:58 😂😂😂😂😂
So stardust is all around us, that’s achingly beautiful.
Great video and narration,
Most of the supernova goes kaboom at 100 millions degres, this is where the TRIPLE Alpha Process happen , and Element Carbon (6) is created.
This is the only moment that carbon is born and matter travel is ejected into space. The remains of those stars and bits ,are found on the earth and many others planets.
They are called Carbonados black diamond, pure allotrope of carbon isotope 12 and 13 , mixing with few elements and mineral, but solid and very hard remaining of the star .
They travel like pollen in the space acting like seeds to fertilize planets .
Most of the planets going through stages of cold and hot, and through the glacial age of the earth, Many carbonado came down, and acted like ram seeds going 100-200kms down the crust .
Modern craters are round, dry and present ejecta in a arc of field, carbonado did act like if you dropping berries in a liquid yogurt , penetrating at a different angle vaporizing in a instant the snow, ice and create a different orogeny of the terrain and lanscape. they are underground those meteorites !!! they contains DNA and RNA...
Carbonados diamond are the remain of those stars and does not belong to the inner solar system type of know meteorite . They are outer system and older than the sun.
The red ring we see in a long exposure astrophotography are the remain of those explosion , The dust travelling in a round and arc shape. The rest of the dust are called nebula.
man gonna use this topic for breakthrough challenge
Nice, supernovae are ALWAYS an exciting topic, good idea. Let us know if you have any questions about them as you go along. Best of luck!
IN the video ( I shot the outro) I mentioned the channel name so that u know to show that you guys did it :)) and love the animation. I'm doing some thing like animation but a little different
That's awesome, and we're honored, thanks so much! When you can, please share the video, we'd LOVE to see your work and help support your videos, too! Thanks again.
wow. I will definitely send it to ur email or I don't know wut after I am done
btw I have finished shooting the data part of it (intro) not to only do the animation
A lot of people watched a long time waiting for a supernova to explode. They missed it because nobody the supernova they were watching was not being updated.
Awsome.
*_[Star that is about to explode: Yay, now I can be like that gamma ray blast!!]_*
*_(Explodes into a spherical energy orb)_*
*_[Star that just exploded: ;-; well so long for being a gamma ray blast]_*
MightyDaAwsomeGuyPlays YT hmm
what animation tool did you use
HERE'S JOHNNY!
Woah this is best
Thank you @Pi!
i am in 7th grade my geography teacher showed this to us , my teacher and my classmates founded this animation funny and very very cool and we continued to talk about supernovas for 2 days , many of my classmates made some cool projects on it because of this video , i never thought that supernovas can make geography classes interesting !!!!
That's AWESOME to hear! You see, anything can be pretty cool when you learn about it the right way. Glad your teacher has a fun class for you, thanks for watching our videos!
3:00 but you didn't explain main point ' the cause of explosion or supernovae or it still a mystery ?
SOTY and AOTY
Its when a star many times the mass of our sun starts fusing lighter elements into IRON in its core that a star will go super nova.And that is because IRON absorbs energy when being created.In the core of all stars their is a battle between gravity trying to crush the star and the energy being released by fusion in the core of the star that allows the core to push out against the crushing force of gravity with an equal amount of force.But when lighter elements begin to be fused into IRON,the core will collapse in on itself because IRON absorbs energy and the core has lost its battle with gravity.As the core collapses the electrons are squeezed into the protons turning them into neutrons as the core goes from 8000 miles in diameter down to a 10 mile in diameter neutron star.But because neutrons repel each other the core now rebounds ever so slightly but so violently that the resulting outwardly moving shockwave creates the fusion of IRON and all of the other heavier elements along with lighter elements as the star explodes as a Supernova.What is left after all of this is a NEUTRON STAR.
Awesome comment, thank you for sharing! The history of how stellar evolution, degeneracy, black holes, Pauli Exclusion, etc. and how we, as people, came to discover and progress our understanding from those discoveries is one of my favorite reading topics! If only cramming all the finer quantum aspects into a five minute video that everyone could enjoy were much more easily done! Thank you again.
Thankyou for your kind words.I wanted to help people get a better understanding of what happens during a supernova.Why do people go through all the time and expense to make a video and yet make no effort to get the basic facts straight.It would of taken maybe 30 seconds longer to better explain what causes a massive star to collapse and then explode as a supernova.I should add one more thing to my first post. An extreme amount of neutrinos are released by the crushing core and they provide most of the energy and thus outward pressure to blow the star apart, creating all of the heavier atoms from iron on up.
Does that hurt us or any kind of effect????
@@mubasherkhan1940 Supernovas are beneficial to humans as they provide elements needed to support life on earth.
what causes the most destruction in a supernova are its shock waves? are shock waves the most devastating effects of a supernova?
Who came here æducate themselves after aespa supernova
how did u make the animations in this video?
I see a good amount of people attempting to correct the video in saying "most stars in the universe will not go supernova" by pointing out the majority of stars are blue and yellow main sequence stars and red dwarfs; all of which will not undergo supernovae when they die.
While this is true, all of these stars will become white dwarfs at the end of their lifespans. It has also been determined that most stars either exist in binary pairs or small clusters. White dwarfs and binary pairs are breeding grounds for type Ia supernovae, and the fact that so many stars exist in clusters is why type Ia's are so much more common than their type II counterparts.
Most stars will go supernova, but not within their main sequence lifespans.

RojoFern Thanks, I will have to read those. If I am to put that together the fact that 97% of stars in the galaxy (and therefore, presumably, the universe) have only enough mass to become white dwarfs, then I am to conclude that most systems will go supernova when the white dwarf cannibalises its companions. But, is it true that most of these systems will result in the necessary matter exchange? That is, are most systems close binary, or will become such?
I would assume general orbital decay and the significant loss of mass during star death would draw stars closer together over time. Even then, you'll find that stars don't typically follow circular paths, and rather partners will have various shaped elliptical paths with differing circumferences. This of course means during periods the pair would be at great distances from one another, and in others they'd be fairly close.
Mass gathering for the white dwarf companion could occur within these periods.
I also want to make clear that I don't believe 97% of stars will go supernova like the video says, and that I simply believe the majority will (I couldn't give you a fair estimate off the top of my head.
Supergiants and hypergiants only make up about 1% of stars, and we can't rule out solitary main sequence stars and the partners of type Ia progenitors that don't collect enough mass from their partner's nebula to themselves go supernova.
Can Someone explain how the ENERGY generated by nuclear fusion gets balanced by gravity which is a type of FORCE as both of these are totally different properties?
2:45 when he said it became a nuclear bomb I got confused how that happens after it runs of nuclear power? that causes the bomb in the first place?
I know it's a little bit confusing. It's like you are saying that after you run of water we will have a water bottle from no where.
That's a good question👏 if you knew the answer plz let me know♥️
Superb✨🎇🎀🎀🎀🎖
0:05 Almost never. Most stars don't go supernova since they need to be very massive to go supernova; our sun will not go supernova.
id rather die freezing anyway
