Supernovae are the most powerful explosions in the universe, unleashing enough energy to outshine galaxies. We have no real metaphor for their power - if the sun were to magically go supernova it would feel like you were being hit by the energy of a nuclear explosion, every second. For weeks.
While supernovae are the engines of creation, forging the elements that enable life, they also burn sterile whole regions of galaxies. So what would happen if one hit earth?

Hey Kurzgesagt
Great video on supernovae! Amazing that we were both working on the same topic at the same time. I hope everyone knows that these videos take months of lead time for both of us so there is no way one video was inspired by the other or vice versa.
We're familiar with Zeitgeist thanks
Endless notifications.. dear God what have I done
Ohhhhhhhhhhhhhhh, I thought the information in this video was from a previous Kurgz video, but now I remember, the video was yours. Thank you!!
eh, what a timing. well complemented 👍
Tu eres el maestro longaniza
Yu also make a vedio on this topic
One of the best things about this TH-cam channel is that it gives science backed information which isn't normally accessible, breaks it down to a level where almost anyone can understand, constantly updates us with new research, and gives it to the public for free. Thank you for what you do, Kurzgesagt
E
SciShow has been doing this for years too though.
"One of the best things about this TH-cam channel is that it gives science backed information" - quoted from you.
I would argue that is the most dangerous part of this channel. One mistake and it could become law, by accident, with no possible way of going back.
@@danielduncan6806 That's why they have a lot of different sources and they work with scientists and experts
Ikr, I can name atleast 20 channels that give you good scientific information!
I love how varied the content on this channel is. One day it's, "Look at this cool ant," the next it's, "Boy wouldn't it be fun if we went extinct?"
And then a deep talk about depression.
@@LennoxParsec and then the fact you have a high chance of getting a auto immune disease in your life time

Your pfp scares me
@@DrowsyFellow good :)
You know you stand zero chance of being affected by a supernova - right?
That was the whole point of this video.

@@ChadtuvaQueen Either or is fine
The amount of times humanity could have not existed because of how the galaxy works genuinely blows my mind.
And how many times Humanity should of end shows how capable we are as well how we are fragile and could end quickly
The universe is a great and cruel world
@Curiosity the ice age and the last human episode and super volcano I was talking about
@@fismail4330 ''cruel'' is a human made conception. The universe is just the universe.
@@higorss Just because something is a human made conception doesnt mean it cant apply to things that arent human.
The Great Filter is probably the strongest reason we have yet to contact intelligent life. Anyone with the tech to reach out and give us a call, probably has the same tech to destroy all life on their planet, like we do. The improbability of our existence is quite large.
What's really fascinating is the fact that we found a layer of increased levels of radioactive iron in the archaeological record and we were able to eliminate any other possibility besides a supernova from 300 light years away.
well... there are alternatives ... but you don't want to think that a civilization advanced to the nuclear age and then killed itself. or a space civilization bombed this world for some unknow reason .
@@unknow11712 Wrong, I want to, but it wouldn't be very reasonable without further evidence :x
The only other possibility that was eliminated was a solar storm, based on the solar maximums, but it’s still possible that the sun did it, just extremely unlikely. Also other solar storms that we know of haven’t caused this effect, which means if a solar storm did do it, it was unbelievably massive.
Nothing in the solar system makes Iron-60. The sun isn't massive enough, and humans can't make it because it requires energy input from either direction, fission or fusion. Also amazing to think about, is the Iron-60 was made in the supernova...and traveled the 300 light years to earth, and arrived in enough quantity to be detectable. Also, any element heavier than Iron is only made in supernovas as well, because of the energy input required for Iron.
The reason they could figure that out is the particular _kind_ of radioactive iron that was found - iron-60. It's only produced by supernovae, and yet it's never found on Earth in mines and the like, as with its "mere" 2.6 mil years half-life, all of it would have decayed away (to cobalt-60) since the formation of the planet.
I absolutely love how concepts from other videos were integrated into the vision of the future. The Dyson ring and solar engine were lovely touches.

Hi, if you are not saved, and would like to be included in the rapture of the church. Believe that Jesus's death on the cross, was enough to pay for ALL your sins , yes ALL ,(past, present and future) That is what the Gospel is about. We are saved by GOD'S amazing grace, through our faith in Jesus's sinless life, death on the cross and resurrection 3 days later . No additional works needed. It is literally that simple.

7:05 screenshot is legendary in terms of aesthetics! Very atmospheric, and an incredible illustration!
Honestly, it's bloody impressive that life can shrug off a supernova even as close as that. Life finds a way.
*they didnt shrug it off
@@yeetusdeletus8254 bro animal life survived. Thats more complex life than the first 3 billion years of life on Earth. I mean as in life survived, not only survived but survived in very complex forms. Like apparently there'd still be insects, fish, crustaceans, plants, fungi, anything else deep in water or soil. Very complex organisms. Not just single celled organisms.
It is impressive how much life (even complex life) can shrug off without dying out entirely.
Of course the beginning of the universe is a theory, and not a scientific fact, that was failed to be mentioned here.
@@andrescavada563 how's that relevant at all to what I said, if ur referring to wether the big bang happened or not, maths doesn't lie.
@@andrescavada563 almost everything is a "theory" there are no "scientific facts"

2:30 im sorry this was literally so adorable the narration with the timing of the art was too kuch for me. Please keep up the great work!
Another amazing video! This channel really has some quality content on it. I always come back to watch whatever the new video is :)
The thing about these videos is they're entertaining, educational, and sometimes tugs at your emotions. Kurzgesagt really is one of the kind.
These videos are TV quality, yet you produce these and offer them to us for free -- not on one channel, but on multiple channels, most of which required translations -- all for free. I respect you. You guys are one of the channels that make TH-cam. (DISCLAIMER BELOW, because there's a lot of debate in the replies.)
A lot of people have taken "TV quality", to mean bad. However, I want to make it clear that I didn't mean the comment as an insult, but as a compliment. It is also important to note that I did mean streaming services, such as Netflix, not cable. Though I spend virtually no time watching either, this comment meant more so that this is quality content, that I could see becoming official rather than a TH-cam operation.
Don't get me wrong, I enjoy TH-cam and consistently watch it, but you also have to remember that some TH-cam channels (such as this one) are more... polished, than others, especially considering that this is the same platform that has the family vloggers, and "DON'T CALL AT 3 AM!!! 😲😲" videos.
RUN FOR YOUR LIFE
@@centralkaufci why ?
This video was uploaded to the German Kurzgesagt channel yesterday sporting the funk label. Funk is part of the content netzwork of ARD and ZDF, which are two German public television channels. German public broadcasting is funded by the 'Rundfunkbeitrag', which is a tax that's legally not actually a tax but binding all the same. In short, Kurzgesagt videos are partly funded by German public television.
@@Steamrick damn that's cool i didn't know that. its good to know that the german government is actually doing useful with tax money instead of wasting it in useless ways lol
@@anustubhmishra It's not actually tax money, it's citizens' money taken in by a private organization for public use. Despite that, it's not optional and people have gone to prison for refusing to pay.
It's... a rather controversial topic.
That said, Kurzgesagt is one of the best uses the money could be seeing.
Great video as always, love the animation of the stars. And the music going harder while going closer is a brilliant detail. It slaps!
6:10 Wouldn’t the increased thunderstorms help regenerate the ozone layer? I read somewhere that lightning creates a significant amount of ozone. Unless I’m mistaken.
This needs to be pinned!
Absolutely, but it's no good if the conditions that destroyed the ozone layer continue to exist. Earth would become a nitrous oxide factory because the supernova radiation is still battering the upper atmosphere.
@@thehochmaster2 Will animals that can use nitrous oxide evolve? A mass extinction event was caused by oxygen in the atmosphere, and now, we need oxygen!
@@Anonymous-df8it maybe, but I think it's unlikely very many exist. Back then, oxygen-consuming life existed. It just couldn't proliferate until algae changed the earth's atmosphere. First we need to find a N2O consuming creature. That's hard too; that N-N molecular bond is strong as hell. Not a lot will convince 2 nitrogen atoms to split. NO2, that's a different story.
@@thehochmaster2 Why would it need to break it apart? I don't think we break up O2 into two oxygen atoms as humans can't actually use oxygen of that form (where they're individual atoms, not bound up)
I first discovered Kurzgesagt back in 2015 with their videos on nuclear energy. I remember thinking at the time, "Wow, this channel makes some great content. I hope they end up growing and getting more attention." Seven years later, my wish has most certainly been fulfilled.
For years I've evangelized this channel to my friends and coworkers as the gold standard of educational content, and I still get giddy when a new video comes out. I've purchased dozens of calendars, posters, and journals, and I will happily continue to support this amazing channel. Cheers, Kurzgesagt!

I discovered this channel when my teacher gave a video from this channel for an assignment in 2020 and I've been watching Kurzgesagt ever since.

the information kurzgesagt provides shouldn't be taken as facts anymore. look up "How Kurzgesagt Cooks Propaganda For Billionaires" video...
This makes me wonder how many solar systems this actually happens to every time there is a supernova.
between one, and four. Space is big.
In the core, the number is higher, but it's still under a hundred.
@@gwouru And due to how short the lives stars big enough to generate type 2 supernovae are, a large portion of those happen near their sibling solar systems from the same nebula, meaning they're not all that much older, and thus haven't had time for life to develop in the first place.
I watch these videos and scared, especially since our ozone layer has gotten weaker since humans began polluting the atmosphere with toxic chemicals. Or the fact these these random events can happen at any moment and could just wipe out our planet…. or galaxy.
@@maximusothunderman Technically our ozone layer is getting so much "stronger" with the pollution that it traps "heat" enough to become it's own power core. Anyway if that's what you're primarily afraid of then your life must be peaceful because random events like these have so little probability of happening in our lifetime and even less to actually impact us that it's actually the least dangerous thing that can exist for us out there. Of course it's different if we look at it in a civilization of species scale as it will for sure happen one day but that's a problem for my grandson's grandson's grandson's grandson's...
@@mynamesbigmynamesbigmyname4757 true. Well at first it was a black hole as something I was worried about. But yeah that problem might not happen for another dozen generations or so.
This is such a great channel. I often forget the channel exists between uploads, and then I'm so happy to remember it that I just binge a bunch of old videos.
This video has the best explanation for the supernovae 😊 Thank you guys! Always looking forward for more learnings through your videos. 🤗
Honest to god Kursgesagt is one of the greatest educating channels out there. With the quick release time of videos and the stellar visuals, it is probably the /best/ of them. Kudos to the Kursgesagt team who give us all the high quality work!

Imaging humanity a 10 million years from now (if we survive) is just mind blowing. If we make it that far, we will probably be all over the known universe and be present in millions of planets.
I really hope we can at least get somewhere before the universe eventually dies, it will take so many years of course. Yet, its not as far as we think it is. At least, I hope we leave our mark before we all go into our restfull sleep.
Even if we can invent FTL tech, we will only ever be able to visit a tiny, tiny part of the universe as (covered in another Kurzgesagt video: "TRUE Limits Of Humanity - The Final Border We Will Never Cross") everything outside our local group is expanding away from us faster than or fast as the speed of light. As mentioned in the above video, 94% of the known universe is already gone beyond the veil

I love these videos, they show us how horribly humanity can perish and then end with a "no worry this won't happen for the next billion years" seems weird, but it always fuels me with inspiration
I mean if you think about it life has had all this time to evolve without being entirely wiped out, what are the chances for that to happen right now in our short lives?
@@OmniversalInsect Some things we are uniquely vulnerable to, but the rest of life isn't. The most obvious example is a human centric disease, however for a more cosmic example consider a powerful coronal mass ejection that is aimed at us. Our modern electronic society would be very negatively affected by that, while the rest of life would just see a pretty light show further south than they usually appear. And in fact we've seen such a thing quite recently - look up the Carrington event.
dont worry supernova is instant, it is like if you eat nuke, it is instant 😊
In 2018, while looking through my telescope I saw this star that suddenly flashed and then went out. I think it was a supernova.
@@vkobevk Only if it's very close by. A more distant, but still close enough to be dangerous, supernova would not instantly fry the planet, as the video explains. It could even last for centuries, as the waves of radiation steadily degrade our environment.

no ikr?? like i dont usually feel this way and interestingly enough, they do it while telling us very alarming things
The best you can do to make the world better is to live your own life as well as you can, contribute to your community where you can, and not blindly follow others when it's the wrong thing to do, even if it's the popular thing to do.
You don't have to be a superhero, just do the best you can realistically do. When people try to take on too much or set their goals too high for the world, they often end up doing nothing, nothing that makes a difference, or just complain and get angry or depressed.
be careful not to choke on your aspirations.

I love that the backing track is an absolute techno-bop that gets more intense as things get worse
Vibing to the music in this, never been so nice to get hit by a supernova.
Surprised to learn there’s no games or books about surviving a near supernova.
3:19 kurzgesagt's music drops so hard a star explodes
When the narrator said, "In any case, you can sleep well tonight, under the beautiful night sky", I had no choice but to look up and admire the sentence, and a smile lit up my face. This is what Kurzgesact does, time and time again, and it just never fails to remind and impress.
Thank you for increasing my knowledge
I absolutely love this channel and the fact thats its free is astoundingly ,
Kurzgesagt has fed my curiosity for eveything science, like i have almost watched all the videos on this channle, keep up tge good work
Just know that your spiking the curiosity of this 12 year old, me,
its so fascinating how the world is so huge , its unfathomable i literally cant explain my happiness with words that this channel even exists. like the animation , how you explain things, and everything it just makes it so interesting eye-catching, cool
I got your book on the immune system, the word fascinating just doesn't do ot justice its so cool how many dumb things can be smart together.
I have no words keep it up
I love how they used just a few seconds of the sound track from the stellar engine video in the end to just enhance the scene a bit more. Love the continuity ❤️
6:45 "We would face food shortages, skyrocketing prices, and wars"
Oh, were we hit by a supernova this year?
Wheres the radiation
its coming later isnt it
@@aligntech250now coming in the newest Russia vs Ukraine update
You did an awesome job! I appreciate the hard work but there was a little mistake the moons shadow was not realistic other than that, A+!
If a supernova hit earth I would call my friend Kevin
This shows how we're still under the whims of nature.
We live if it wants us to live, we die if it wants us to die. We can never do anything againts it.

I love the amount of awe you can stuff into those little birds.
More pessimistically, there's no point in worrying if a star could immediately go supernova within 4 lightyears of us anyways. What could anyone even do?
Well, tell it to stop, first of all
Tell it, no thank you, actually we’re all set here
There's not even any stars under 4 light years away from earth. As the video points out all possible stars that could go supernova are far enough away that they don't pose much or any threat to life on earth so we're safe.
"No thank you, we don't want anymore visitors, well-wishers, or distant radiations"
@@error_found isn’t the Sun close to Earth?
These videos are both extremely terrifying yet calming.
Yeah I’m scarred for life rn
@@BradyT-800 nah we're all fine, and even if one were to blow up let's say 100 ly away...well, you have 100 years left which is more than enough xD
For anyone who wants to dwelve deeper, the mechanism that accelerates particles inside the travelling supernova remnant is called (1st and 2nd order) Fermi acceleration!
Dear administrators, well done 👏 a truly marvellous video. Back then, this channel inspired me to learn more about astronomy and cosmology . I still learn from your videos and teach my students to watch the channel.
9:12 -- nice throwback to the star engine bit you guys had in an episode a long time ago.
Also...can't help but have: "LET'S JUST PICK UP OUR SOLAR SYSTEM......AND MOVE IT SOMEWHERE ELSE" echoing in my mind, in Patrick's voice, while that part hit.
Yeah, I knew I wasn't the only one who thought that.
8:16 When day breaks in a nutshell
ComE oUT iNTOo ThEeE SuUNNN.
Thanks for the information
I really do like that transition from the analogy to the suns effects on the Earth from about ~3 million light years away with the beach one and then in the next paragraph, the animation goes underneath the water of the beach into the beautiful depictions of the coral reefs to talk about how scientists are able to understand that Earth a long time ago was hit by some super novae remnants and that caused some radio active minerals (rocks) to form on or underneath the sea beds.
There are always so many new things to learn in a Kurzgesagt Video, like I would’ve never imagined that a Supernova happening like hundreds of lightyears away can still greatly affect us here on Earth.
Vielen Dank für eure Arbeit, Kurzgesagt Team!
