I've already seen dozens of videos on TH-cam about how a Supernova works, but this is another level. A complete and very well illustrated lesson in under 20 minutes. Veritasium never disappoints.
Yeah but what the real scientists are talking about a 12k year cyclical micro nova not a supper nova. You know this fact but seeing how you are a shill for the NWO agenda21 we get this nonsense. TALK ABOUT THE MICRO NOVA CYCLE NASA DISCOVERED IN THE 60’s. Talk about how it is predicted to happen again in 2043. Talk about how climate change can be explained by earths magnetic field weakening while the suns energy is ramping up to maximum. Talk about how we should be preparing for this next biblical coming that we have been warned about in every Bible on the planet.
i’m extremely proud of the way my dad explained supernovae to me when i was about 5. he told me to put my hands out, facing each other, and then he put his hands on mine. he then told me to push outwards, as hard as i can, while he pushed inwards, which made my hands collapse. he said that when a star wasn’t strong enough anymore then gravity won. now that i’m older, i’m really enjoying this more comprehensive explanation
@@dot1298 I haven't been following up on the war much but I am damn sure that they are good off. The US has given practically it's lung to the country; I'm sure the UN is probably helping; and there are so many donations and even some organizations relocating families out of the warzone. This feels pretty petty to comment. How about you donate there? Or how about you donate to homeless women and children? Or how about you donate to cancer treatment? Or Children's hospitals? Or to schools that don't have proper funding? Or to the residents in the Ohio Train Derailment? You get what I'm saying now? Honestly this comment I felt was disrespectful. People can donate to whatever they want; whenever they want; however they want. That's it. If you believe someone should've donated with THEIR money; you can instead with your own money. And before you even question me; no I did not donate anything. Period.
I'm an undergraduate student majoring in Astrophysics and Planetary Geology. Thank you SO much for this video and your sources, one of my professors was looking into an extinction event and I was curious as well. This has given me a starting place on research to piece things together! While I was pondering on possibilities I remembered this video. Veritasium, you are doing an amazing job with your channel. I have sent many of your videos to friends to help explain concepts, they always love your content too!
Whenever I watch an almost 20 minute long Veritasium video, I never lose interest throughout the video and it's consistently gets my attention. The pacing of him talking quickly and pausing to make a transition makes it easier to retain the information. Also his voice is very clear and comprehensible. As always amazing stuff Veritasium, you never fail to get my attention.
Him and Vsauce are my favorite TH-cam learning channels. Veritasium seems more "normal" interesting while Vsauce keeps your attention by being "weird" interesting.

Last year, I almost joined the Brian fields research group after listening to his presentation on this topic. He talked about how they had to look through sediment samples to find traces of Fe-60. I thought it was so cool that we could learn so much about the history of our cosmic neighbourhood just by observing earth. It's amazing to see this topic explained so well.
It doesn't happen "just by observing earth". It's actually a lot of different scientific disciplines coming together to understand what we're looking at. This is even more impressive than you make it sound.
Jesus Christ is the propitiation for the whole world's sins. They that believeth and are baptized (with the Holy Spirit) shall be saved; but they that believeth not shall be damned. Those led by the Holy Spirit do not abide in wickedness. *God is ONE manifesting himself as THREE;* the Father, the Son, and the Holy Spirit! Bless him! *For these three are one.* As I am led by the Holy Spirit, nothing I state is a lie, but the truth of God. Anyone who tells you differently is misinformed or a liar. They do not know God, nor led by him. Anyone who *claims* to be a Christian and is against what I am doing, and where I am doing it; the Holy Spirit does not dwell within them, they lack understanding. They know not God, read his word, and their religion is in vain. Do not hear them, they will mislead you, the lost cannot guide the lost.
When you trust in God and cast your cares (worries, anxiety, depression, suicidal thoughts) upon him, they will be NO MORE! Know that there is power in the name Jesus Christ! His name casts out demons and heals! The world is wicked, evil, and of the devil. I too, was a wicked sinner of the world before I opened my heart to God. I am living proof of God's work and fruitfulness! He is an active God who hears the prayers of his! God's children are set apart (holy) and righteous. The devil is a liar that comes to steal, to kill, and to destroy; that includes your relationship with God! Open your heart to God, repent of your sins (he will forgive you), and let him direct your path. Draw nigh to God, and he will draw nigh to you. Cleanse your hands and purify your heart, lest you walk with the devil and follow him to hell.
I watch an obscene amount of science youtube, and love supernova videos. I learned a ton from this video. You have done something wonderful here Derek.

Small addendum regarding the name Supernova that you mention (1:20): Kepler's teacher and mentor, Tycho Brahe, was the first to publish a book concerning a new star (stella nova), namely SN1572 or "Tycho's Supernova", which appeared 32 years earlier (TWO visible supernovae in a lifetime and NONE since!) Brahe's book was "De nova et nullius aevi memoria prius visa stella", ("Concerning the Star, new and never before seen in the life or memory of anyone").
@@JensRiggelsen Yes, but you only wrote "two visible supernovae in a lifetime and none since", which isn't correct. No mention of them having to be in our galaxy.
I always appreciate the value of your productions. The bit where you showed how a star fuses the different elements as time goes on and for how long blew my mind.
It blew my mind, too, although I had first seen this information a few years ago at an open-house presentation of the Astronomy Department at the University of Manitoba. I don't remember all of the time periods though. Does anyone have a reference for each element, all the way to iron? I was disappointed this video didn't give all of the times. I think in the end it was minutes, or seconds!
Clarification: There are stars that go supernova AND form black holes as well. The formation of a black hole doesn't mean that there is no supernova, which is clarified quite late in the video and might lead to quite some misunderstanding in the first place. Still this is another perfect video!
@@rahulbanerjee8867 when the mass of expansion is high enough to force the mass density apart, its explosive expansion stops and all that mass recondenses. If their isnt enough mass to form a black hole, it forms a neutron star instead.
The fact that a supernova thousands of light years away can cause a measurable change in our atmosphere is absolutely mindblowing to me. The fact that a gamma burst 2.5 BILLION light years away caused a noticeable effect is similarly mind-melting. Astronomy stuff really can be incredible. Thanks for putting together a great video on this!
But the GbR got me thinking. Wouldn't it only effect us if one of the two beams is targeted directly at us? Seems like that lowers the chance of a hit even with an explosion within range dramatically to me. I didn't full get from the video if we have to be in the beam or not, but if so, it seems much less impressive to me than the supernova to me. You focus all the energy into two directions, of course it has a much higher range. Its like comparing a rifle to a grenade to me, but I could have understood it wrong.
@@electricpaisy6045 you are right, a GRB is a very narrow stream of particles, like a rifle, as you very cleverly put it. A stray bullet coming at us in this vast space is very unlikely, but GRBs are much more frequent than supernovae and are deadlier from further away.
yeah exactly I thought we could safely watch the big cosmic fireworks from like a few lightyears away xd but this really changed my perspective on how big these "fireworks" actually are!
Wow... amazing. Let's think about some other nonsense, make-up crap... How about Santa Clause? Heard about him? He will blow your mind! He travels at the speed of light!
I've seen countless videos and understood partially, but this is the first time I actually understand how and why of a supernova. The amount of simplicity it went to explain this, my salute to Derek for making space and science fun and simpler.
I was surprised a few years ago to learn that gold and heavier elements are unlikely to be created in a standard supernova but require a more extreme ultranova or similar event such as star collisions to produce special elements like gold. That just adds to how lucky we are to have such abundance of uranium, gold, etc on our planet.
Love your videos man. I'm a regular joe with no notable math or science skills whatsoever but for some reason your explanations makes sense to me. You should get a Nobel prize for educating the masses in all sorts of subjects. Thank you for the various topics over the years and I hope it will be so many more lessons to listen to in the future. Space is damn scary and amazing at the same time!
Veritasium is consistently better-written, better-edited, and better-explained than any other TH-cam channel I've found yet. I wish more science-oriented channels had standards as high as Veritasium.
I've never seen a video this in depth yet clear about how all this works and how our history is with these things. This is the most interesting and fun video I've seen from you yet
Watch a video called "When Stars outshine Galaxies" by a channel called "But Why?". This video is good, but the gold standard of any supernova video is still But Why?'s video. Goes into even more detail but somehow is still not overwhelming.
Great video! I did a degree in physics and astronomy and can say this was a great, easy to understand review of some of our favourite cosmological objects and I really enjoyed you linking some of the supernova events in the past with extinction events on earth :) I didn't know about some of those connections, thanks as always for sharing!
You absolutely missed his point at the end as probably most of the thumbs up to your reply. If it hadn't been fro a cosmic dice roll a long long time ago WE wouldn't be here!!!!!!!
Great work as always. My nieces and nephews are always asking me space questions and ill answer but also show them these cool animations which really gets the point across.
Given the vastness of spacetime in our universe, it is so amazing to have such a violent type of event that occurs in a short enough time scale comparable to a human lifetime, yet frequent enough that we actually observe a number of them within our short history.
Derek, this video was simply MONUMENTAL. :) Well done!! Seriously, wow. I've watched your channel for *YEARS*, and I personally believe that this is one of your most profound and awesomely constructed videos yet. I have no idea how you do it. Kudos, and... I certainly wish I could comprehend as much as I've ENJOYED over the years! Almost a decade now, I think, TBH... 🐲✨🐲✨🐲✨
This is one of the best physics videos I've seen on TH-cam. It is amazing how thoroughly you showed that theorized physics concepts have real physical effects on the Earth that we can measure and see. It's wild how neutrinos seem so intangible but yet are so impactful in supernovae and can even alert us to their presence before they become visible!
I love the in increasing eloquence of narration on this channel--and the extravagantly gorgeous graphics, such as at 08:50, or 13:40, which are brain-beguiling!
@@Flesh_Wizard good sir, u need to define near, because as mentioned even a star going hypernova 150 MILLION light years away, caused mass extinction on earth
I'm left in awe at the explanation of how some tiny, tiny, weightless, harmless Neutrino... detonates the largest bombs in the known Universe. Just amazing how super-large events can have the smallest origins. Love this. Thank you.
It took me a moment to fully understand just how much of a difference the density changed when going from an iron core with a diameter of 3000km down to a neutron star with a diameter of 30km. At first I thought "hmm, 100x smaller is quite a bit smaller, but doesn't seem like enough for how insanely dense a neutron star is". Then I remembered that volume is affected by a square compared to the diameter. So, even though the core "only" goes from 3000km to 30km, the volume is about 1,000,000x smaller. Thats some DENSE matter. Especially when you consider the fact that iron is already relatively dense, that's absolutely insane.
Most are typically around 10km diameter when fully neutron stars, but imagine how dense and rugged the core of the star was that it can withstand the rest of the star rebounding off itself at 25-30% the speed of light!! Well it doesn't actually, because it all flattens down further becoming a neutron star.
@@nuntana2 Recent simulations show that the rest of the star does NOT rebound off the freshly minted neutron star. It has no time to fall onto it. The NS is formed in well under one second, something like 50-100 milliseconds. This new NS is approximately 100 billion kelvins hot. The luminosity of such a hot object is difficult to imagine, my quick-and-dirty calculated estimate is ~10billion solar luminosities ... from every square meter (!!!). The surface of NS would cool off quickly with such insane power output, but there is sufficient energy transfer from the interior of NS to its surface by neutrinos, which allows it to shine for about 7 seconds before its luminosity starts to drop. This deluge of gamma-rays generates a very powerful shockwave, it impacts on the the rest of the star before this "rest of the star" makes any significant falling movement into the cavity left from the formerly existing iron core.
I have always admired your ability to elegantly describe the beauty of the universe. Amazing. You are one of the reasons I'm pursuing a degree in physics.
Good luck! It's difficult but rewarding. I did bachelors and masters in physics, and loved it. It's also buys you a TON of options professionally, and can get you some very high paying jobs.
A pretty broad range @Robert Jušić . As a physicist, in college you'll likely work with: 1 - Coding, like python, Labview, Python or Statistica 2 - TONS of math, you pretty much get a bachelors with a very similar skill set to a mathematician 3 - Equipment training, if you work in research 4 - Technical communication skills: From presentations and paper writing so after graduation, if you learn to communicate your skill set, you can be an analysist (in lots of industries), data eng, software eng, professor, researcher, or most types of engineering roles. My background is in applied physics, but I've worked my entire career as a process eng in manufacturing. The big part is learning how to communicate that the skills you have are useful. Communicating how learning advanced mathematics can help in a real world situation
@@tacobanana_forever curently on my 2nd year of mechanichael enginering and constantly anxious that im not gonna find a job that im truly happy or usefull at. How did you menage to comunicate that your skills are usefull?

@@AsinineComment I assume whatever sapient species lived in orbit of the star that went supernova On a related note: Has anyone here played or heard of the game Outer Wilds?
Veritasium is one of my favourite channels on TH-cam. The explanations are lucid and give the intuitive feel to understand complex ideas. Thanks Derek!
The Crab Nebula story was amazing. It's so easy to look up think of the night sky as static, but the entire universe is all moving faster than I can even comprehend.
Exactly. And this shows how bad we are at imagining the scale of the universe. The universe is so large that even objects moving close to the speed of light feels like they are at rest! Just mind boggling!
Yep, it's always moving but it seems static at times because of the massive time scales. It's amazing to think that when we see the Crab Nebula, we see it as it was 1,000's of years ago due to the SOL !
Thanks for the update about the Gamma Burst Ray observed on 9 October on Earth. I learned most of the astrophysics a long time ago and certainly like the comprehensive video display of it, but the consequences for what the effects were on Earth and on it's life that are discovered since are fascinating. It is amazing how much information you have compressed in a single 20 minute video and still be clear about the many subjects. I also like that you show the scientific abstracts. Exceptionally well done!
this is one of the best vids you have ever made. Very technical, yet easy to understand by even most of my classmates who never even HEARD of a super-nova. I'll be pushing this one on friends and family.
Facinating video as always, Derek. Could you please make a video in the future explaining the creation of heavier elements (r- process, s- process and p- process)? It blows my mind to think of the extreme conditions required to create them. Makes me appreciate them that much more. Thanks for all your hard work.
I would vote for this as well. I am hearing all the time we are made from stars and all the heavy elements were made there before. But when? How about elements not on the fussion "paths"? I see how H, He, Ne, C, Si, Fe... are produced. How about all the other elements? Why there are high amounts of matter made of elements "behind" Fe, if the system needs an extra energy to build them? And why are they all locked in the planets? Are they? And why different planets of the same system have different distribution of the heavy elements (I mean any other than H or He)? It would be nice to learn this topic through a similar video :)
"The blood of life shines red from the death of former stars" (A poem by Bertil Gelland, freely translated to English. It assumes that those novas are the only source of iron, and that iron is what makes hemoglobin red)
Hello, hope you are well. I'm very interested in this poem, but i can't seem to find it complete, could you be kind enough to share it? or share a place where i could read more about Bertil Gelland? There are many results by searching the name and i'm unsure to which one you refer.
Exactly this topic was my bachelor thesis in geology. Super fascinating stuff, tons of implicatons in both directions if we were able to detect them. From dynamics of our galaxy to the history of earth and life.
@fck peace Lines in space photos is because of the telescope's mirror. The light reflects within the structure of mirror or telescope causing these lines to appear. Well the image on right is edited. So these lines are added artificially.
Man! This one solved all my curiosities about supernovae.Straight to the point and I can clearly understand what you want to explain in this content.Thanks mate!
These videos are great! animations, music, and Derek the narrator, all top-notch quality! thanks for this Derek and the team! I think you have the best quality educational videos on earth!
i friggin love being at this time in science where so much is known but so much more is unknown, and we have just enough info to look in the right direction to see amazing things.
Another awe inspiring, informative and visually stunning video by Derek. It was possibly the greatest thing you have done is drop the graveyard shift at the neutrino detector and come to TH-cam! After all, at least on the science topics on youtube, you are a supernova light source here! Many stars have faded away but you kept us in light!
Gentleman, what a masterpiece. I'm surprised I've never seen information about stars like this before, especially considering a watch a whole bunch of astronomy videos. I'm really surprised and amazed. Thanks 💚
Amazing video! One of the best explanations of a Supernova that I was looking for a while now and you happend to make one today! That's why I love this channel. Has an amazing narrative in telling a scientific story and we all love a good story. Unfortunately I was also hoping for a quantum explanation to what happens when a star decides to go the other way and become a black hole. That would have been amazing! Maybe in the near future, I really hooe.
I remember reading that XKCD What-if blog about lethal dose of neutrinos that talked about the hydrogen bomb in your eyeball analogy. I laughed my lungs out at the time and am so happy it was mentioned here.
I never really understood what actually causes the explosion. No one else who explains supernova talks about neutrinos. They simply say when iron accumulates in the core the star explodes. Thank you for the extremely clear explanation.
It's crazy that not so much time ago, I used to buy dvds or even blue rays with documentaries about this topics. The fact that nowadays it's free on TH-cam it's amazing, and with the same quality (even more maybe) I'm very thankful with this kind of creators, the are the real MVP
Well, this is undoubtedly one of the best explanations about how stars and supernovas work I've ever seen. Science is one of those areas of life in which, just as soon as we think we understand a thing, we find out more about it--or in some cases relearn what we thought we knew. Thank goodness for the guide who takes us along on that journey and is just as fascinated along the way as we are (I'm talking about you, Comrade Derek).
Honestly one of the best Veritasium videos. There have been a lot of other explanations about supernovae but this one goes a lot more beyond "ooooh star collapse but then star go boom, cool light"
Man i LOVE this Style of fusing Learning and Fun together. Gives me the Urge to recommend others who mastered this Style, to random People. I wanna name-drop Oversimplified, Hbomberguy, Some More News, Tier Zoo, Madvocate and so many Others but thats often perceived as random-spam.
A minor error at 8:21: While some very massive stars can theoretically go straight to being a black hole when they collapse most Black holes are thought to be the result of core collapse supernovae in stars that are too massive for the remnant to be a neutron star. This is when the remnant is so massive that neutron degeneracy pressure (and even quark degeneracy pressure) are overcome. Dr. Derek, you are the modern-day Richard Feynman. Your ability to explain incredibly complex concepts in such a way that a layman is able to understand is extraordinary and I can only dream of sharing the planet with more minds like yours.
@@somejerk1520 Do you have a cell phone with a gps? That works because space, gravity and therefore, black holes are reality, whether you're ignorant to it or not.
@@DougVandegrift GPS has been around since the 40s since it is and always has been tower based. Trans-oceanic flights have no benefit from GPS since there are no towers in the ocean. Remember when that Malaysian flight went missing? Seems odd in a world with 20,000+ so-called satellites keeping an eye on everything.
What I find really remarkable is that since the formation of our solar system around 4.5 billion years ago nothing much has happened in our part of the galaxy, allowing life to form and continue on earth to this day.
Really interesting - great video. I love the way you illustrate the massive light from a star explosion being seen by human eyes and make the pupils expand though. This is the direct opposite of what happens - pupils constrict in light and dilate in the dark to capture as much light as possible.
Translated: I have never seen an animation that is this intuitive and in detail, about the events that are going on within a star at the very moment it explodes. This was great. Many thanks.

It is so cool tbh i know that humans were not really meant to find out these things or even comprehend them. We were meant to be oogaboogaa at best.
Small addendum regarding the name Supernova that you mention (1:20):
Kepler's teacher and mentor, Tycho Brahe, was the first to publish a book concerning a new star (stella nova), namely SN1572 or "Tycho's Supernova", which appeared 32 years earlier (TWO visible supernovae in a lifetime and NONE since!)
Brahe's book was "De nova et nullius aevi memoria prius visa stella", ("Concerning the Star, new and never before seen in the life or memory of anyone").
Underrated comment.

Clarification: There are stars that go supernova AND form black holes as well. The formation of a black hole doesn't mean that there is no supernova, which is clarified quite late in the video and might lead to quite some misunderstanding in the first place. Still this is another perfect video!
thank you for clarifying what the video clarifies itself
yes
So when do blackholes form and when do supernovae?
@@rahulbanerjee8867 when the mass of expansion is high enough to force the mass density apart, its explosive expansion stops and all that mass recondenses. If their isnt enough mass to form a black hole, it forms a neutron star instead.
A stellar type black hole will always be preceded by a supernova, and the more massive the star, the bigger it will be.
The fact that a supernova thousands of light years away can cause a measurable change in our atmosphere is absolutely mindblowing to me.
The fact that a gamma burst 2.5 BILLION light years away caused a noticeable effect is similarly mind-melting.
Astronomy stuff really can be incredible. Thanks for putting together a great video on this!
It's a U- Bomb ...
But the GbR got me thinking. Wouldn't it only effect us if one of the two beams is targeted directly at us? Seems like that lowers the chance of a hit even with an explosion within range dramatically to me. I didn't full get from the video if we have to be in the beam or not, but if so, it seems much less impressive to me than the supernova to me. You focus all the energy into two directions, of course it has a much higher range. Its like comparing a rifle to a grenade to me, but I could have understood it wrong.
@@electricpaisy6045 you are right, a GRB is a very narrow stream of particles, like a rifle, as you very cleverly put it. A stray bullet coming at us in this vast space is very unlikely, but GRBs are much more frequent than supernovae and are deadlier from further away.
yeah exactly I thought we could safely watch the big cosmic fireworks from like a few lightyears away xd but this really changed my perspective on how big these "fireworks" actually are!
Wow... amazing. Let's think about some other nonsense, make-up crap... How about Santa Clause? Heard about him? He will blow your mind! He travels at the speed of light!
I've seen countless videos and understood partially, but this is the first time I actually understand how and why of a supernova. The amount of simplicity it went to explain this, my salute to Derek for making space and science fun and simpler.
I was surprised a few years ago to learn that gold and heavier elements are unlikely to be created in a standard supernova but require a more extreme ultranova or similar event such as star collisions to produce special elements like gold. That just adds to how lucky we are to have such abundance of uranium, gold, etc on our planet.
Actually fission stops at nickel not iron. It's a myth that iron is the most stable element, but nickel is more stable
Regular super nova make gold and lots of other stuff. hypernova make black holes from which nothing escapes.

They can't so they accept mediocrity.
Yeah, but Derek has more than 10 million subscribers and a team working with him... not all channels can afford that.
because Derek is interested in cinematography too thats why his videos are different from others

Watch a video called "When Stars outshine Galaxies" by a channel called "But Why?". This video is good, but the gold standard of any supernova video is still But Why?'s video. Goes into even more detail but somehow is still not overwhelming.
Great video! I did a degree in physics and astronomy and can say this was a great, easy to understand review of some of our favourite cosmological objects and I really enjoyed you linking some of the supernova events in the past with extinction events on earth :) I didn't know about some of those connections, thanks as always for sharing!

Great work as always. My nieces and nephews are always asking me space questions and ill answer but also show them these cool animations which really gets the point across.
Given the vastness of spacetime in our universe, it is so amazing to have such a violent type of event that occurs in a short enough time scale comparable to a human lifetime, yet frequent enough that we actually observe a number of them within our short history.
Derek, this video was simply MONUMENTAL. :) Well done!! Seriously, wow. I've watched your channel for *YEARS*, and I personally believe that this is one of your most profound and awesomely constructed videos yet. I have no idea how you do it. Kudos, and... I certainly wish I could comprehend as much as I've ENJOYED over the years! Almost a decade now, I think, TBH...
🐲✨🐲✨🐲✨
This is one of the best physics videos I've seen on TH-cam. It is amazing how thoroughly you showed that theorized physics concepts have real physical effects on the Earth that we can measure and see. It's wild how neutrinos seem so intangible but yet are so impactful in supernovae and can even alert us to their presence before they become visible!
I love the in increasing eloquence of narration on this channel--and the extravagantly gorgeous graphics, such as at 08:50, or 13:40, which are brain-beguiling!
Love how Veritasium took this topic and really went in depth with different scenarios.

@@David-cv1seyou either have a dangerously low braincell count, or you're really bad at ragebaiting
It took me a moment to fully understand just how much of a difference the density changed when going from an iron core with a diameter of 3000km down to a neutron star with a diameter of 30km. At first I thought "hmm, 100x smaller is quite a bit smaller, but doesn't seem like enough for how insanely dense a neutron star is". Then I remembered that volume is affected by a square compared to the diameter. So, even though the core "only" goes from 3000km to 30km, the volume is about 1,000,000x smaller. Thats some DENSE matter. Especially when you consider the fact that iron is already relatively dense, that's absolutely insane.
Most are typically around 10km diameter when fully neutron stars, but imagine how dense and rugged the core of the star was that it can withstand the rest of the star rebounding off itself at 25-30% the speed of light!! Well it doesn't actually, because it all flattens down further becoming a neutron star.
volume of a sphere is a cube relationship to the radius
@@nuntana2
Recent simulations show that the rest of the star does NOT rebound off the freshly minted neutron star. It has no time to fall onto it.
The NS is formed in well under one second, something like 50-100 milliseconds.
This new NS is approximately 100 billion kelvins hot. The luminosity of such a hot object is difficult to imagine, my quick-and-dirty calculated estimate is ~10billion solar luminosities ... from every square meter (!!!).
The surface of NS would cool off quickly with such insane power output, but there is sufficient energy transfer from the interior of NS to its surface by neutrinos, which allows it to shine for about 7 seconds before its luminosity starts to drop.
This deluge of gamma-rays generates a very powerful shockwave, it impacts on the the rest of the star before this "rest of the star" makes any significant falling movement into the cavity left from the formerly existing iron core.
I have always admired your ability to elegantly describe the beauty of the universe. Amazing. You are one of the reasons I'm pursuing a degree in physics.
Good luck! It's difficult but rewarding. I did bachelors and masters in physics, and loved it. It's also buys you a TON of options professionally, and can get you some very high paying jobs.
@@tacobanana_forever what kind of jobs?
A pretty broad range
@Robert Jušić . As a physicist, in college you'll likely work with:
1 - Coding, like python, Labview, Python or Statistica
2 - TONS of math, you pretty much get a bachelors with a very similar skill set to a mathematician
3 - Equipment training, if you work in research
4 - Technical communication skills: From presentations and paper writing
so after graduation, if you learn to communicate your skill set, you can be an analysist (in lots of industries), data eng, software eng, professor, researcher, or most types of engineering roles. My background is in applied physics, but I've worked my entire career as a process eng in manufacturing.
The big part is learning how to communicate that the skills you have are useful. Communicating how learning advanced mathematics can help in a real world situation

The Crab Nebula story was amazing. It's so easy to look up think of the night sky as static, but the entire universe is all moving faster than I can even comprehend.
Exactly. And this shows how bad we are at imagining the scale of the universe. The universe is so large that even objects moving close to the speed of light feels like they are at rest! Just mind boggling!
Yep, it's always moving but it seems static at times because of the massive time scales. It's amazing to think that when we see the Crab Nebula, we see it as it was 1,000's of years ago due to the SOL !
Thanks for the update about the Gamma Burst Ray observed on 9 October on Earth. I learned most of the astrophysics a long time ago and certainly like the comprehensive video display of it, but the consequences for what the effects were on Earth and on it's life that are discovered since are fascinating. It is amazing how much information you have compressed in a single 20 minute video and still be clear about the many subjects. I also like that you show the scientific abstracts. Exceptionally well done!
Im so glad I found your channel, your voice, explanations and visuals are so well done and beautiful. Thank you!
this is one of the best vids you have ever made. Very technical, yet easy to understand by even most of my classmates who never even HEARD of a super-nova.
I'll be pushing this one on friends and family.
Facinating video as always, Derek.
Could you please make a video in the future explaining the creation of heavier elements (r- process, s- process and p- process)?
It blows my mind to think of the extreme conditions required to create them. Makes me appreciate them that much more.
Thanks for all your hard work.
I would vote for this as well.
I am hearing all the time we are made from stars and all the heavy elements were made there before.
But when?
How about elements not on the fussion "paths"?
I see how H, He, Ne, C, Si, Fe... are produced.
How about all the other elements?
Why there are high amounts of matter made of elements "behind" Fe, if the system needs an extra energy to build them?
And why are they all locked in the planets?
Are they?
And why different planets of the same system have different distribution of the heavy elements (I mean any other than H or He)?
It would be nice to learn this topic through a similar video :)
I really like the artwork and new-ish animation style you’ve added to the channel.
@dont read my profile picture.
Why?
By far the best super Nova explanation I've ever seen
"The blood of life shines red
from the death of former stars"
(A poem by Bertil Gelland, freely translated to English. It assumes that those novas are the only source of iron, and that iron is what makes hemoglobin red)
Hello, hope you are well. I'm very interested in this poem, but i can't seem to find it complete, could you be kind enough to share it? or share a place where i could read more about Bertil Gelland? There are many results by searching the name and i'm unsure to which one you refer.
It is a correct assumption. There is no other plausible mechanism for generating large quantities of iron-53.

Well, this is undoubtedly one of the best explanations about how stars and supernovas work I've ever seen.

What an outstanding episode! Please more space content!
A minor error at 8:21: While some very massive stars can theoretically go straight to being a black hole when they collapse most Black holes are thought to be the result of core collapse supernovae in stars that are too massive for the remnant to be a neutron star. This is when the remnant is so massive that neutron degeneracy pressure (and even quark degeneracy pressure) are overcome.

What I find really remarkable is that since the formation of our solar system around 4.5 billion years ago nothing much has happened in our part of the galaxy, allowing life to form and continue on earth to this day.
Nothing much except 5 mass extinction events though :-). If more cataclysmic events had occured probably no one would be here to think about it.
2:13 The amount of photons emitted to produce such significant force is really mind blowing to me. Thank you for the vid
Really interesting - great video. I love the way you illustrate the massive light from a star explosion being seen by human eyes and make the pupils expand though. This is the direct opposite of what happens - pupils constrict in light and dilate in the dark to capture as much light as possible.
Finally, someone who talks about supernovae and on why those that occur nearby could be devastating.
This take is somewhat scary too.
Another brilliant video Derek. You deserve a Netflix series.
Nah youtube is better.
So that Netflix can cancel it after 2 seasons? No thanks.
Imagine the amount of effort they put to publish this amazing video 😲
This man is brilliant! Love your videos.
Nunca había visto una animación tan intuitiva y detallada de lo que sucede en las estrellas al momento de su explosión. ¡Fue grandioso! Gracias. 😍
I saw one this year and really thought if it gets bright again tomorrow - we'll never know
🤞🏿
Translated: I have never seen an animation that is this intuitive and in detail, about the events that are going on within a star at the very moment it explodes. This was great. Many thanks.
@@lll-xo6nk ...Man i LOVE this Style of fusing Learning and Fun together. Gives me the Urge to recommend others who mastered this Style, to random People.
I wanna name-drop Oversimplified, Hbomberguy, Some More News, Tier Zoo, Madvocate and so many Others but thats often perceived as random-spam.
It's crazy to think something so astronomically far away can literally burn our skin on earth during hot days.
Ok Frankie.
