Supernova

[URAbunnylover2]

is this actual footage waaah?

[JRR12100]

@URAbunnylover2 of course not. theres a 1:1,000,000,000 chance that we can see a supernova when it explodes, and theres a 1:1,000,000, chance that some random astronomer is looking there, that exact second.

[URAbunnylover2]

@JRR12100 oh yeah XD and the chance of getting it on video will be 1:1,000,000 too

[alkiethebear]

thats fucking pritty

[MrGullideckel007]

xD get down guys the most important thing is, that the supernove looks like a dragon

[TARDISES]

ITC: idiots.

The sun will not go supernove. There is not enough mass in it.

It will mvoe ot the red giant stage after 5 billion years. Earth might survive, it might not, the planets would shift orbits further away. Mercury and Venus have no chance to survive make their time, and Earth will be fried regardless. After 2 billion mroe years, the sun will go to a white dwarf, and slowly cool off to a black dwarf.

also, about hte black hole comment? not always in a sueprnova. Can be neutron stars

[Neopulse00]

Supernovas don't make sound

[eejay30]

WHAT THE!!!!!!!!! A SUPERNOVA EXPLOSION AND IT MAKES A NEBULA!!!!!!!!!!

[Rasverix82]

@eejay30 they do

[foozbong]

Beautiful rendering of a supernova.

[shazs]

Honestly, stars can do a lot of things under a lot of conditions. Some may go black hole or they may blow up. Nothing is ever a for sure and the universe can surprise us. Our star is far too small to collapse into a black hole so it will just detonate and be gone. It requires a star many times more massive to collapse into a singularity.

[yobreezycuuh69]

i like diss 1

[MyRotflCopterGoesSoi]

I thought supernovas went "OMNOMOM" and turned into a black hole?

[MsThetruthseeker]

(And nothing is hidden from your Lord (so much as) the weight of an atom on the earth or in the heaven. Nor (is there) what is less than that or what is greater than that but is (written) in a Clear Record.)

[herczegh00]

very beautyful

[michelXShawn]

was this spost to be real?

[RuffleTheTeacher]

Good thing we don't live close to any stars!..... Oh,shit.

[vanzetti7]

IT'S UNICRON!!!!!!!

[Megamanrocks3]

i get that one

[maplestorystudios]

lol dinasours ^^

[TheKellzIsALie]

our sun can't supernova because its mass is not high enough. stars larger than 8 times the mass of our sun potentially could supernova because they are so large that the gravity would cause a massive collapse and then an explosion. since our sun is smaller, gravity would not be powerful enough to collapse the sun with force enough for a supernova. After it explands It will simply blow off most of its gasses and become fainter and fainter. No big boom, sorry.

[dgvfsds]

my science teacher told me last year in yr 7 that the sun will expand and then eat the earth and all the other planets but she it wont happen for another 17billion yrs or so.

[frederik002]

Our sun wil expand in about 5 Billion years, check the movie from 'The secrets of the sun' (5th part) search it on youtube.

[dgvfsds]

no its 17 billion yrs, my science teacher even said so and i can tell u now, shes one heck of a science teacher

[jontu125]

its going to expand 5-6 billion years and it will only swallow the three first planets mercury,venus and earth.

[dgvfsds]

yeah, i figured as much but my yr 7 science teacher knows wat shes talking about

[jontu125]

well i dont know how much she knows but im sure the sun isnt going to last 17 billion years

[farinheit2celsius]

Dude, your teachers wrong. The sun will expand in 5 billion years, look it up online. 17 billion years is how long the universe has existed.

[jontu125]

except that scientist have estimated that the universe is 14,6 billion years old.

[farinheit2celsius]

What's a few billion years off, jk

[dgvfsds]

well, maybe ur right but anyway still the earths gonna be eaten

[maplestorystudios]

ARGHHHHHHHHHHHHHHHHHHHHHHHHHHH­HHHHHHHHHHHHHHHHHHHHHHHHHHHHHH­HHHH well humanity got a great brain we gonna do something before then even faster lol ^^

[LunaticKnight]

Our Sun does not have enough mass to expand, collapse in, and explode. The Sun can expand, as it burns out and collapses, that's about it. Any star that explodes into a supernova is no less than nine solar masses. One solar mass is the total mass of our Sun. A star at around 8.5 solar masses I could see going supernova, but anything less is really doubtful.

[marcelodelagoXD]

the sun in about 5 billion years, will be bigger, supernovas happen to bigger suns. ours willl just grow, collapse and die

[DarkStarshades]

there is a skeleton!!!

[RJL738]

Thanks for the video. Supernovas happen about once every one or two centuries in our galaxy.

[miagijj]

AWESOME,

[narutons15]

Gdyby z naszym słońcem stało się to samo to jeżeli wybuch by nas nie zabił, to na pewno by nas oślepiło ;]

[RogerRoids]

there is another galaxy heading for ours in 3 billion years, and both super black holes in the center will form 1 and suck up both galaxy's. Earth will be sucked up, or set into deep space forever. This will happen before the sun explodes.

[francia016]

OMG! you are so tragic!

[wolverine005]

No, they will just form a larger galaxy.

[RogerRoids]

yes, but a black hole will happen first.

[wolverine005]

What are you talking about?

[RogerRoids]

it's a known scientifict fact.

[wolverine005]

Rofl, I have no idea what you're talking about. "black hole will happen first"? What do you mean? Black hole will happen before the galaxies combine? I don't understand what you are trying to communicate...

[RogerRoids]

To start, the is a supermassive black hole in every galaxy. when that galaxy hits us, the 2 supermassive black holes will become 1 huge supermassive black hole, and it will go out of control.

[wolverine005]

I don't deny that, I was denying the part where someone claimed that all the matter from both galaxies will be "sucked" into the super massive black hole. That would not happen, a quasar would form, and the energy emitted from the quasar would push matter away from the SMBH and eventually the quasar would be "sucked" into the SMBH. When the SMBH's combine, huge amounts of radiation would be released, Most likely destroying all life in the galaxy, but not matter.

[RogerRoids]

either way, this will happen before our sun does a super nova.

[wolverine005]

The sun does not have enough mass to become Super Nova. It will eventually shed its outer layers, but not in a Super Nova.

[kamranh3]

then why do scientests say themselves that the sun wiil turn into a supernova?

[wolverine005]

They don't, not legitimate Scientists anyways.

[kamranh3]

Show me proof.

[wolverine005]

Show you proof of a Scientist not saying that it will turn into a Supernova? Please explain how...

[kamranh3]

I don't know find a video clip or something!

[wolverine005]

Search anything in youtube, it will list videos with Scientists not saying that the sun will go supernova.

[aerosewall]

you correct, the sun WILL NOT go supernova, it will definately get to a giant branch , planetary nebula then cool off, and take it from me cuz i'm one of those scientists that study these things

xx

[jontu125]

thats in the wrong order the sun will expand into a red giant then cool and shrink to a white dwarf that uses the helium created by the sun in its fusion when the helium finally runs out the white dwarf cant anymore keep its ball form and will become nebula there might be mistakes but i think thats what will happen to the sun

[farinheit2celsius]

The sun will fuse all it's hydrogen into helium, then fuse all it's helium into carbon, then the outside will expand into a nebula while its core will turn into a white dwarf. Eventually it will turn into a black dwarf.

[maplestorystudios]

o_O

sorry kinda new to the BLACK DWARF

i guess its a planet's core that not giving anymroe light...

but if it was black hole o_O i was confused

[3DPlanets]

@maplestorystudios

It's a star's core after the original star has shed its outer layers into a planetary nebula. The core is a white dwarf, but it cools down because it has no nuclear reactions. Eventually it fades to black. Wikipedia is your friend.

[maplestorystudios]

as i heard:

red giant>swallowing>explosion like a baloon

but why we care about it its like billions of years away

[walkonthesun]

omg stop crying about everything :/ you will be dead be4 u know what happend

[calosity]

Our sun will likely not create a super nova. It will expand as it burns through the elements and eventually will fade to a white dwarf.

[kamranh3]

then instead of burning to death we will freeze to death. I'd rather burn

[calosity]

No, we would still burn. It would increase its size as it burns through the elements, burning everything living off the face of the Earth, if not engulfing the Earth itself. Definitely wouldn't freeze to death, thats for sure.

[JeffreyOKay]

Our sun would be predicted to engulf all of the inner planets, but that is for quite a few million years I've heard... Nothing for anyone alive today to worry about.

[aerosewall]

:)

xx

[suraj555]

No,

if there a big star explode everthing wil die or mutatie

or...

the galexy wil get bigger

what do you think?

answer!

[jtr10411]

not really usually when a big star dies it collapses on itself and gravity keeps pulling and pulling to one spot until making a black hole.if that wat u were asking

[jhonnygesponny]

true, supernova's are rather rare compared to the ammounts of black holes

[jtr10411]

yeah i know huh

[anderaina]

by the time sun explodes, Earth will already be destroyed by us -_-

[twisterlemonade]

The Sun doesn't explode.

[scaremenga]

nope, becasue its not a blue star, so it dosen't not have enough anergy to explode...

[krischrissirkris]

our sun CAN burn out though as it doesnt have an infinite amount of energy

[3DPlanets]

@anderaina

You're forgetting that there are planets that could be terraformed. Mars could be terraformed now. When the Sun becomes a red giant, Pluto will warm up and could then be terraformed. By the time the Sun is a white dwarf, we'll probably have also colonized other star systems. Humans could probably conquer the galaxy, and Earth will already have been destroyed by the Sun.

[edderd8]

@anderaina The earth will already been destroyed by the sun before it even explode. Earth will heating up to 1730 degrees in 1.1 bil years. Then will the earth spinning aroudn the sun for 7.? bil years (totally dead and even ( no oceans no mountains, no live, no plants,...) Then the sun will suck up the Earth and then the sun will explode after a while. Not sure if it has the power to explode anyway

[JorickHorn]

@anderaina The sun won't explode. It will become a Red Giant, which will at least make earth uninhabitable (liquid rock) and probably swallow earth entirely. After that, it will become a White Dwarf. The Sun isn't massive enough to explode.

[andy2070]

if u think our sun will supernova your wrong it is not big enough not enough gasses it will only turn into a red star will not supernova or anything bt it will go into mars arbot and well teh world would burn but thats not supposed to happen for another 5.6 bilion years so nothing to worry about

[cupidmcduce110]

wow people are leaving very intillectual comments but im 12 som i dont know how to do that so what happenes if the sun exploads and if youe a scientist or just very smart explian it in a childish or explianabul way and if you are a christian explian it to kkkkkkk bye plz explain reply to this plz

[thisguyflip]

black what? you mean neutron star?

[HoshoNoKaabii]

lordweizegger there aint anything named a black dwarf.

[MrAngy]

Only because the Universe is not old enough for them to exist. It would take some 100,000 times the age of the universe for a white dwarf to cool down that much.

[javierjjs]

theres no sound in space

[xxxDARTHxxx]

lol...

[rumute]

if a sun went supernova and no-one was around to hear it, would it make a sound? :D

[Ziggy1614]

not even if you where right next to it. theres no sound in space.

[lordweizegger]

and the white dwarf turn to a black dwarf.

[SaturnineXTS]

Stars of solar mass don't go supernova, they go nova. After a nova, a white dwarf remains, after a supernova, a neutron star or a black hole remains.

[qwertytheseond]

I thought a star could only become a black hole if it collapsed back in on itself? Surely if it went nova (or supernova) a sufficient quantity of mass would be ejected so that it wouldn't be able to?

[SaturnineXTS]

If the mass is greater, the gravity gets greater to a point. When a core of a star is really heavy, it will keep on collapsing to aneutron star (about 20km diameter) or even smaller, becoming a source of a black hole. Lesser starts will finish as white dwarfs the size of Earth.

[elvisdustin]

that is amazing

[lordweizegger]

you are all wrong.the sun is not big enough to go supernova when it is a red giant when it dies.

[gzac95]

this is a common mistake, some supernovae explosions involve very, very small stars called white dwarfs, usuallly found in binary companions systems tat accrete matter from the companion red giant (or main sequuence star, if it close enough) type II supernova are of big stars.

peace

[Dimentinalslingshot]

Interesting.

[devinsbrother]

You are right in a way though-dwarf stars only novae, not supernovae

[aerosewall]

Careful.... Think about accretion mechanisms, and binary systems. thats a real big clue for you!

there are a few excellent doctrates on astro-ph concerning this issue

peace

[devinsbrother]

Type A (1) supernovas are when a red GIANTs supernovae and turn INTO dwarf stars.Type b (2) supernovas are when a red GIANTS supernova and turn into black holes.Dwarf stars dont supernova :P

[aerosewall]

mate! that is really bad science

of course dwarf stars can go supernovae, they have to be present in binary systems, with a core mass reaching 1.38 solar masses via accretion from the red giant, this is a type 1a supernova explosion! the red giant does NOT sNova into a white dwarf, the white dwarf SNova and usually totally obliterates the companion star

peace

x

[TheKellzIsALie]

Aerosewall- You are very correct! Type II supernovas (involving red giants) turn into Neutrino stars.

I'm doing my final project on Supernovae at UCI- I thought I'd watch these videos for fun, then got caught up in the comments!

[aerosewall]

yay fellow nerd!!!!

i too am writing my finals on supernovae, specifically the remnant and expansions rate of the shock fronts just entering the sedov taylor stage, from free expansion, i have chosen to cas A because of the inhomogeneity of the shock front and that fact that we have radio, optical and x ray (from chandra) for this. interesting points to notice on cas a are the jets, from shocked medium rather than fast rotating neutron star at the nucleus. good luck with your thesis :D

peace

xx

[aerosewall]

what area of SN are you studing, is it SNe or SNR?

blessings

xx

[12345ct12345]

you have that wrong

our sun is expanding now

[elvisdustin]

sun

[elvisdustin]

ower sum is going to blow up i mean go supernova

in a few 100 years

[Ali3nat0r]

You're a fucking idiot. A) Our sun is nowhere near big enough to go supernova, and B) it isn't even gonna start expanding for another several billion years. :)

[devinsbrother]

Part B is wrong

[aerosewall]

no our sun is very unlikely to go supernova, what is likely to happen is that as it expands, (enters the giant branch of it life)reaching to about where mars now is.. it will go to a plenetary nebula state and the cool of slowly over the next hundreds of millenia

peace

x

[devinsbrother]

That could be right, but what also could be right is if our star expands into a red giant and supernovae in 5 billion years.Scients and astronomers dont know for sure

[aerosewall]

when the sun goes into planetary nebula, it ejects a vast proportion of its mass into its surrounding medium, i dont have a clue why you would believe that our sun could go supernovae, my astrophysics lecturers have never mentioned anything about this

can you explain it please, with reference to the physics and the papers you've read

[04wingedangel]

wats a super nova

[DarknessXER]

A supernova is a big star which uses its last amount of energy in a big bang.... I mean the star blows up!

[04wingedangel]

oh shit that is so cool

talk about dieing in a big blast

[aerosewall]

this is a common mistake, some supernovae explosions involve very, very small stars called white dwarfs, usuallly found in binary companions systems tat accrete matter from the companion red giant (or main sequuence star, if it close enough) type II supernova are of big stars.

peace

x

[elgranto7]

in real life that would take years for the blast to go out fully

[def4d]

That makes me think of meteor traces, at the end of video!

I hope that Carl sees that :)

[joshig1983]

After the explosion, is this just a stretch of a semitransparent image?

[russia19941]

what will hapen whit the left owers ????

[dazman76]

Some of the leftovers will eventually collapse back in on each other (as the clouds of gas and dust condense), and eventually form new stars. If the stars are large enough, they will also eventually go supernova and the whole thing starts again :)

[elgranto7]

maybe form a star one day

[phoenixshade3]

For anyone who cares, this is the Cassiopeia A supernova remnant. From the initial "explosion" to the end is a period of about 330 years.

[35chris3]

when u look at the pieces of the star u can see some sort of dragon xD

[beatdeat]

Hahahaha, i was just about to say that!! Sound waves require a substance to travel through. In our case, here on earth, the substance is the ever-present air we breath. But in space, there are no gases to transmit the sound waves to our ear drums! Pretty nifty video though.

[Ghostkol]

Erm....... there is no sound in space, so we shoudnt hear the boom at all.

[Cipirano]

look in wikipedia "VY Canis Majoris" and then tell me what gonna happen when this star explodes ??

[elgranto7]

universe is a big place, it wont do much

[aerosewall]

a casual remark if ever i heard one :), do you know that the reason you and i exist is because of supernova explosions,(which form the larger atoms in the periodic table) if it weren't for them very little beyond iron would exist. so in fact i could do a lot

love

a-m

x

[elgranto7]

yes i do as a matter of fact XD, were all stardust in a way, kinda nice to know :)

Grant

[MiGhTy567]

this would be bigger than any nuclear bomb x 100000....absolutley huge

[cannatacr]

cool!!! very good thank you!!!!!!!!!!!!!!!!

[Drydareelin]

ouch, not nice, wicked film

[solarity890]

*laughes* I had the speacker on so....jumped at the boom.Yes it would indeed suck to be in that. But it's pretty to watch!

[row18iscrap]

black holes -.-

[JeoNeo123]

i was misinformed by the supernova explosion in futurama lol.

[Boybattin]

That would suck to be in that

[saxbob2006]

WOW!

[MejiMelodi]

it's really beautiful T_T (tears of joy)

[UltraGorillaz]

it looks like some sort of monstet lol

[heathey2]

amazing isnt it!!

[ohelliot91]

cool!
