So this means that my great great great great great great great great great great great grandmother was a star?
No you great great great great great grandmother was the dinosaurs

He must be 8:36 about this
dead 8:36
I'm trying to understand for my school work but it's so complicated and I don't really understand it 😭
IDK Man, he explained it pretty well. But it's not for everyone I guess.
This is about the simplest explanation of the life of stars you'll find. Watch it again and it might make more sense.
8:36
whoever gets this reference is a king(queen)
So helpful! I really needed this
fantastic presentation of astrophysics at the level understandable to high school level, explained clearly, and visually to make this hard subject accessible to learners. I also like the clearly crisp English sound of the narrator. Many Thanks for your service.
thank you so much!
Much more helped me for my Project.🙂
Thank you man this is very helpful for my test this week :D !
very knowledgeable......Loved it
Great video. Thank you.
Looks the part but poorly explined and a little miss leading, for example, the outer later don't just drift away, the process of the core compressing, starts the fusion reaction with the helium, once this starts, the pressure of the core is greater then the gravity, making the star blow up like a balloon and more less blowing the outer layers away.
Very informative description about life span of a star.thank you and good luck
Thank you for your videos, they are really good.
Thanks. Is a very great explanation about a formation of stars and elements of life.
+Oriol HIDALGO ASENSIO Thank you 😊 👍🏻
Hello, just one little thing, necessary temperature for H fusion is approximately 10 millions K not 10 billions.
I can't understand properly because i m not so familiar with the terms of astronomy.But its interesting.
where are the links in ths discription
Amazing just amazing my amigo
0:49 it looks like a bear
You`re wrong.
I saw a goat lol
damn. thank you for this.
great video!
The best vedio onlife of a star.
dang this makes me realize that I wouldn't have existed if my parent stars didn't die as if they didn't a nebula would have never formed, and I wouldn't have been made guess that also means I won't be able to meet them ether.
odd in a way for us to exist we need other stars to die.
Just Awesome!
Amazing..
Someone please answer this -
The Dust and Gas gets compressed due to gravity ( @1:45 ) .
There should be some mass for gravity to exist, right ?
so, is some physical thing already present in center ?
The dust & gas are the matter causing that gravity
how old is the sun?
So where does the electricity the star created go. and does the bigger one make more or less or does the smaller one make more electricity. And witch have more magnetism. ??
Didnt think id get a reply.
A red dwarf will burn all its hydrogen not just the hydrogen in its core. That is why they live a trillion years or more. But with red dwarfs once the hydrogen fuel is used up that is the end and the star doesn't leave behind a corpse it just blows off its layers into space. Or so it is assumed.
Can't find a better video than this to explain the lifecycle of stars ✨... Really Appreciated...
"nukelar", "nukelus", "nukeli:.... are killing me. I can't take it.
Theonly thing I disliked about this video.
Well, one more: Kelvin is not = to Celsius.
is that kerbal space program music in the background or have I gone mad?
Don't forget the photosphere on stars.
What is the point of learning about space or stars at schools you might want to be an astronomer or something but learn about it when your
Getting taught at the astronomy school
Sorry if this angers someone I’m only 12 I just hate school
This video is pretty though
So cool
We still have 5million years to develop light speed
Deloon 5 billion*
@@trulyfog actually 1 billion.....since after 1 billion year....sun lumionsity gonna increase a lot until earth surface temperatute can easily reach 100 celcius
Mi gusta my friend very cool.

He says 10 billion degrees C, but it says 10 billion K and F. And cirrect me if im wrong...10 billion is a bit too hot is it not?
15 minutes, god damn Enzelmo I got places to be, things to do.
Please continue to make astronomy related videos! I'm subscribing!
Excellent video, thank you - deserves a *_lot_* more views.
Subbing now.

Despite the odd mistake, this was pretty entertaining and informative. I'm surprised that a few people can only focus on how you pronounce the words :/
So my great great great great great great great great great great great great great great grandma was a very bright person?
Can a basketball orbit a star
im watching this for online class
edit: i failed the class lol
Therefore, we are all stars
Humans are star children🙏🙏🙏
Our star will probably get to carbon before becoming a white dwarf. Basically a huge and dense diamond.
Nuculear? Nuculeus? Nuculei?
Also, the "core" of a red dwarf type star running low on nuclear fuel isn't exactly accurate. These small mass stars are fully convective, that is why they last so much longer than larger stars. The nuclear reaction of turning Hydrogen into Helium does only occur in the core of any star, but in a red dwarf the entire mass of the star is continually churning inside of it. The entire mass of the star is available for fusion. So it won't be just the core running out of fuel, but rather the entire star.
Large stars, like our sun, are not fully convective and therefore their cores do indeed run out of nuclear fuel. Their is still enormous amounts of hydrogen available in the outer layers, but it has no mechanism of transporting that fuel to the core. Still larger stars will actually build up layers of heavier elements as the size of the core shrinks and runs out of available fuel. It eventually shrinks to the point where the temperature rises enough to fuse new elements out of whatever is existing in the core, potentially all the way up to nickel.
And yes, I do mean nickel, not iron. The largest stars will produce elements as heavy as nickel through fusion, and it does create energy. The nickel produced this way has very short half lives and quickly decays into iron, or cobalt and then iron (idk remember the exact type of nickel produced or its decay processes).
No red dwarfs run out of fuel for 10T yrs
Great work for humanity. Wishing you all the best 😊🙏
So we all are born of stars!! I love your video, it's so informative.🌈🦄⭐👑🦊
"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."
@@nmcnemis You are absolutely right.
I was reading wikipedia articles about space. Thank you for.unfucking my mind!
Amazing=ASTRONOMIS is FUSHION = LIFE !!
Maybe you'd better view it again... without the drug(s).
:P
Who is the narrator?
To any of my physics class that pressed on this video. Stop looking at the comments and actually watch it
Nuculus?
WRONG betelgeuse is a red supergiant
Yes dude
🐐🐐
i subed!!!!!!!!
Thanks!!! 😊👍🏻
star life time.come
Nicely done.
One request: "Nuclear" is "Noo clee arrr, " not "nyu cyu lar."
Thank you.
The centre of an atom is a nucleus not a nuculous!
Come on electricity university for you
haiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
I have to watch this for science hw
62 years is still too young I'd say 80 years is old enough
Ok heres how Black dwarfs was named:
Scientist 1 "i just discovered a new type of, umm thing!."
Scientist 2 "oh cool what SHOULD we name it?"
Scientist 1 "umm, i dont know. I guess Its White and Its small. Im just gonna be racist and Call it White dwarf"
10 years later
Scientist 2 "remember the White dwarf we discovered 10 years ago?"
Scientist 1 " Yes?"
Scientist 2 "Its Black now..."
Scientist 1 "EVEN BETTER!"
Sorry if any of you are black
Pls pls pls I'm not racist I just found it funny.
louie springett thanks for the compliment and this isn’t a racist joke it is a joke mocking racist people
Fucking nerd
Nano Rasmus was this suppose to be funny in any way?
You know Joe is mad when he watches this video.
@Crimson Lens OFFICIAL who is Yuri Tarded?

The massive black holes at the centre of every galaxy were probably the very first stars to form(but I am guessing here).
We don't know for sure, but it's theorized that supermassive black holes were formed from quasi-stars, stars 1000s of times more massive than the sun that could only form in the early universe because everything was denser. These quasi-stars had a black hole at the center due to the insane density and mass of the star, and radiation pressure from matter falling into the black hole kept the star from collapsing in on itself (though it eventually did)
It's speculated that these quasi-stars could have basically "jump started" a large black hole that we see today as supermassive
Good good good good great
last minute review anybody?
2:11 Kelvin ≠ Celcius.
Well.. ist just 273 degrees different.. soooo.. does that really matter at this temperature?
@@einar5172: Not if you're trying to prove man-made climate change. For that they use "fluid" laws of physics.
@@KutWrite Wdym
And at this point 273 degrees is negligible
But the global warming thing we are taking in terms of major catastrophies in just 4 degrees so its not negligible then
I almost like all parts of the video. But knowing that my grandparents were stars is hilarious. It's unbelievable how people came up with this crazy idea. :D Thanks anyway. Cheers!
You say it's crazy why?
What's your theory and the support of same?
Excellent as ever

9:23 That is not an image of a supernova. It is the Homunculus Nebula.
Aren't nebulae formed the same way, though?
@@KutWrite Depends.
Planetray Nebulae are formed from the puffing off of the outer layers of a sun like star, between 1-8 times the mass of the Sun. (The sun is the absolutely smallest a star can be and still produce a planetary nebula)
Supernova remmentants are formed when stars >8 times the mass of the Sun destroy themselves.
@@shinystarmiestudios4179 Thanks.
@@KutWrite You're welcome
I think its just safe to say that this wont help me now
But it will eventually
Gravity is weak electricity magnetic field will ok sorry school teacher oil crazy bull about dark matter ECT look into electric universe
human's are star children's
Cari Marquez more like star's dust.
Classification of stars is ESSENTIAL for understanding of the star's evolution. Do you know that stars are classified as O,A,B,F,G,K,M? Do you know HR classification? Without it you clip is just empty talk and you are wasting people's time.
I'm reading Stephen Hawking's "A Brief History of Time" and came to this video when I reached the chapter of the book on Black Holes.
Great video bro.
Practice saying nuclear and nucleas though xD
Actually red dwarfs can last up to 10 trillion years. Still liked the videp though awesome channel
And that bloody book says the earth, moon, stars were created in six earth days.
I have to say the notion that humans were formed from the elements blasted away from a a super nova 12:20 is beyond ridiculous. How matter could self organize on its own to form something as complex as a person is more than unproven. It’s a silly kind of faith. I remember when I was in the tenth grade and our biology teacher told the class about how spontaneous generation was a common held belief for thousands of years. The whole class burst out laughing. It’s amazing that “science” has reverted back to this. That something can come from nothing and that that something can self organize into us. Sorry I don’t have that kind of faith. It’s easier to believe rabbits really do come out of hats. Having said this I do appreciate the rest of the teaching on lithe life cycle of the stars. I find it fascinating . Thank you.
Nucular fusion. Nuculus. Your pronunciation is bothering me.
So basically life is a freak accident, or...
...or the inevitable outcome if this process has a gazillion years to continue in an area the size of our universe
nuke-yu-lur
my teacher makes me watch these quit pls
It would help if you knew how to pronounce nuclear correctly
How can the narrator hope to be considered credible when he doesn't even know how to pronounce an easy word like nucleus, nuclear, or nuclei?
CrankyPants fancy a bum?
