Really Big Stars

[psycho3968]

Sort of puts you in perspective hey?...i love the cosmos...just knowing my atoms are from star stuff and will one day return to the cosmos is very cool.

[So1othurn]

Want to see something really big? Thats what I said to her.

[TheAGamer12]

hey guys, if you press the snowflake while watching this video, you will learn that it snows in space! im a genius

[Salty123123]

But will it blend?

[SpeedinHawk]

So VY Canis Majoris is technically about 5 times wider in diameter than our solar system? Pretty boss.. 'Nuff said

[SatanFang]

nice but you got the wrong colors.

[gr33nlion]

Woooooooooooooooooooow

[AlpineFisher1]

There's like a million of these kind of vids, will they ever stop?

[ROFLMAO2950]

Is the moon not about 1/4 of the diameter of earth, i think that scale is wrong?

[MrJudas666666]

yeah the moon is too small. the diameter shud be same as width of north africa :p

[damaged01]

Wanna see something reeeally big?? /giggity

[TonyBtheEG]

This video makes me happy.

[TheHeavensucks]

@TonyBtheEG What u mean?

[TonyBtheEG]

@TheHeavensucks Bizarre question. It makes me happy to know my insignificance.

[DragonUltraMaster]

0:34 - Uranus XD

OMG, I have a big anus 

[leahcimrac]

I love these videos thanks. Is it true theres a supermassive balck hole thats event horizon is bigger than VY Canis Majoris?

[destroyusall]

@leahcimrac first, a black hole with the mass of the earth would only be 0.7inches across, now most galaxys are formed by a blackhole (its what creates the shapes) now if a blackhole with the mass of the earth is only 0.7inches across, the one at the center of our galaxy is, wait for it, 6.7 billion kilometres, and theres even another smaller one next too it, being eaten by this daddy of a beast. so to answer your question, yes there is. if you wish to read up on it search Sagittarius A-star

[cheesenugget38]

I lol'd hard when he said "wanna see something really big?"

[DIGIMICH]

compared with the bigger star, I feel tiny O_O

fantastic vid!

[roadkill1001]

Phowar, this intro has got me hooked already (unzips trousers)

[Dannyk1981]

this blokes voice is soo annoying that im never goin 2 watch this vid again!!!

[keltdevangel1]

Deneb is an A-class,too..and again, it strangely appears YELLOWISH in this video

[RapLibrary]

after the first centence in this video i paused and looked at my dick

[jayerrbee]

Uranus Is Pronounced Ura-nis

[dennisang007]

hi!but i got a stupid question here....uhm all other stars belogs to wat?plz reply asap

[RandomStuff1O1]

At least with VY Canis Majoris.

[bububilibala]

but Deneb not suppose to be red,it suppose to be blue.

[darksneaker2000]

Ok with this video in mind, I need to ask a maybe stupid question. Is our sun among the smalest stars we know of or is it the same way around? On a scale in sice 1 to 10 where is our sun???

[cassiopeiaproject]

@darksneaker2000 As you can see from the video, there are some really big stars, but there aren't that many of them. Our star is pretty average in size when you start counting how many are larger and how many are smaller and how many are about the same size.

[ZeaosIJJI]

@cassiopeiaproject there are not many of them?

you must be kidding everyday we discover star which is huger than the other one.;

[Jon58004]

@darksneaker2000 4.9/5

[boipinoi604]

@darksneaker2000 5

[Singetally]

@darksneaker2000 Our sun is a main sequence star, so it is medium size. Most stars are main sequence stars, therefore our sun is a common/average star. I suppose a 4.5-5/10 on the scale.

[jasminetomca]

@darksneaker2000 those largest stars are supergiants or hypergiants, in the last phase of their lives before exploding - they weren't nearly that big when they were young. i dont know how much bigger our sun will get right before it explodes, but its diameter will be a lot larger than it is now - maybe out to mercury's orbit or farther... anyone know exactly??

[rattinox]

They are all different sizes and colors because of: a)how old they are b)what they burn for fuel and c)how they burn that fuel

Time for another hit.

[spidey678]

Wanna see something really big? My dick.

[Corruptedinfernal]

@spidey678 lol i was going to say some shit like that..

[keltdevangel1]

Deneb IS white!Cygnus's main star is one of the most beautiful WHITE stars in Universe!

[superfar2]

Amazingly Grazy!!

[SuperUniverse555]

Nice texture, it's sooo cool! And also, Rigel supposed to be blue not white. By the way, I've seen so many huge stars in the video, it's so cool!

[abbeyroad1993]

"wanna see something really big?"

That's what he said

[BikerChapterOnline]

being an hypergiant star means this star is about to explode ? :o

[KutasusWielgus]

my dads balls are bigger

[KoolCohen]

@KutasusWielgus

How would u know?

Did you get a gud look at yur old man's balls when he pressed them to yur face?

[VicTheMouth]

Wanna see something really big? So many places you could go with that. :)

[VicTheMouth]

Cool video and thanks for uploading. On another note, no offense, but I think you pronounced aldeberon wrong. I think it's pronounced al deb err on

[Nugwrangler]

@VicTheMouth Nop.Uncorrect.

[goldangel100]

......wow.....if that BIG star was our sun, it would instantly burn our whole solar system into debris!

[lmc6506]

Right. Sirius A is kinda is not yellowish. It's whitish. And Deneb is supposed to be blue.

[RichardCannonwalker]

I can't even imagine if that star blew up into a supernova!!!

[eL1m1n8r]

jesus. ive been watching this everyday for a week. and im still amazed.

[eL1m1n8r]

that is one big ass star o.O

[cronskyispixelated]

BEATLE JUICE LOL

[RadeonX0X]

So the size relation of Earth and VY Canis Majoris would be equivalent of that of a human and bacteria?

[RichardCannonwalker]

@RadeonX0X, think smaller than bacteria. Smaller then GERMS!

[cellerd00r1]

check out R136a1 star in the tarantula nebula its bigger than VY Cepheii by a long way

[Jujudesjp]

the real moon is much bigger! the real moon is 1/4 earth, not 1/8.

[JapanNerd]

Makes me feel so tiny in comparison. Makes you wonder how hot the planets in their solar system, gets. Our planets must be cold in comparison.

[ins326]

Gigantic Aliens... =)))

[1RadicalOne]

Why is your version of Sirius yellowish? Sirius is A-class.

[cassiopeiaproject]

@1RadicalOne We show it as primarily WHITE but we could have added more blue. We were focused on size more than spectral class.

[1RadicalOne]

I see yellow.

The center is white, but the limb is orange yellow - according to the computer, FFF0D4.

[Nugwrangler]

@1RadicalOne Correct!

[uut0]

how come rigel is white while the others are like somekinda yellowish orange

[cassiopeiaproject]

@uut0 Star color is a direct result of the surface temperature of the star. Blue giant Rigel is hotter than the red and yellow-orange stars.

[Nugwrangler]

@cassiopeiaproject Yes.

[seinfeldfan7898]

the guy sounds like a pedophile lol

[6SpAr6TAN69]

he, he, it never fails they always mumble their words they speak of UR ANUS

[shabzl33t]

Wanna see something really big? watch my Dick!

[alejogomist]

ñongis ñongis

[CuppaS00p]

The gravity near VY canis majoris must be fucking intense as hell.

[MrKingElvis]

And I thought I had a pretty huge cock..

I've just lost my erection :(

[YoZZii66]

holy shit .. :D

[scott93257]

Do these stars have a solid surface or are they primarily gaseous?

[cassiopeiaproject]

There are no stars with a solid surface; all are gaseous.

[atisaseret]

Actually, YES and NO - A Neutron Star is SO Dense that it has a 'Crust' which is 10 Billion times stronger than steel. It's Gravity is so intense that light will bend back towards the surface. But you're right, except for the density of a Neutron Star, most Stars do not have a solid surface, they are gaseous.

[empyrionin]

@cassiopeiaproject There are not solid or gaseous stars, they are all layered. They have an atmosphere, then concentrated gas, then gas-liquid mixture, then liquid, then plasma, then solid-liquid core. A star is comprised of matter of diverse states, some stars are even comprised of quark matter, or neutron matter or degenerate matter.

[ShortytheSquirrel]

@cassiopeiaproject Neutron Stars have solid surfaces because their matter has been condensed so much.

[CuppaS00p]

Stars are pretty much just enormous balls of flaming gases

[TheDarwinman]

excellent

[Awhiffofsuspicion]

mm, your vid called 'universe' does a pretty good job cass.....

[Awhiffofsuspicion]

isn't scale a wonderful tool, if the sun was the size of a grain of sand our galaxy would be roughly the size of the moon's orbit around the earth and alpha centauri would be 20 miles away. or, if a quark were the size of an armchair, the armchair would have to be as big as the universe. wow. 'in' is just as deep as 'out', in fact we need a vid showing the true scale of size. (planck-light horizon)

[MeLover99]

Coolz

[Ultdeed]

Our star will become a supergiant. It will extend out to just about the tip of Earth.... And burn earth as we know it. Good news, Its NOT CY-Canis Majoris, which would be a very unpleasent sun to have.

[Quantummechanic100]

Vy Canis Majoris' size and shape are subjects of doubt. Visual photometry is not sufficient for stars with enough circumstellar dust to reprocess the visual and red fluxes into the thermal infrared.

Others also believe that Vy Canis Majoris is a normal supergiant with a diameter of 600 solar radii.

[gwendance]

Hi, my name is Dylan, and I found some mistakes. First of all, if you skip from Betelgeuse to VY Canis Majoris, Betelgeuse would be only a few pixels. Second, you skipped some stars between Betelgeuse and VY Canis Majoris. Those are:Montocerotis, KY Cygni, VV Cephei, and some others. I dont know. I'm 55 pounds because my name is Dylan but I like the video. Greetings from USA, which is in North America.

[punaniswabber]

betelgeuse is smaller than antares

[eestlane9125]

where did you get the 3d planets?

[cassiopeiaproject]

We made them from flat maps in a 3-d modeling program called After Effects (Adobe)

[beswick1111]

hi nice vid

about that VY canis majoris, its the biggest star in the milky way, is it possible theres a star bigger than it in another galaxy?

[cassiopeiaproject]

sure.

[beswick1111]

would u care to elaborate abit more?

how bigger could it be? and how far could it be and which constellation etc...??

is there a maximim size a sun can be before its impossible to be so big?

[cassiopeiaproject]

Hypothetically, the largest possible star would be a cool hyper giant star similar to VY Canis Majoris. And the coolest possible hypergiant would be about 20 percent cooler than Canis Majoris and about 25% larger in radius.

[beswick1111]

another question, are their any planets around canis majoris? could there be any life on any of those planets if they were in the 'good zone', not too close and not too far from that sun?

[cassiopeiaproject]

We have not detected any planets around this star, but there could be planets, and if they were in the "good zone" as you put it, they could possibly sustain life. It is a red hypergiant, so the "good zone" would lie in a different position from the "good zone" of our own sun.

[1997xander]

@cassiopeiaproject

I'm not sure if they could support life canis majoris probably sends out large amounts of radiation so that planet would need to have a heck of a magnetic field,a gigantic ozone layer,and some pretty radiation resistent life

[b29349]

@cassiopeiaproject would the psychics work if atom and it's a miniature structure of a galaxy?

[cassiopeiaproject]

No.

[swirlcrop]

Nice video.

[sidewaysfcs0718]

cus if it is i think we just found our new home when the sun blows up ...that is ..if we can travel lightyears in space to get there.

[sidewaysfcs0718]

if its bigger ..would that suggest its life is longer? like hundreds of bilions of years instead of our sun's aprox 10-15?

[cassiopeiaproject]

For main sequence stars, the lifetime gets shorter as the star gets more massive.

[sidewaysfcs0718]

oh ...thats not pleasant to hear :|

[PlanneCrash12000]

These videos are really cool! I dowloaded a bunch of them on my iPod.

[AiryBlasters]

SUBTITLED PLEASE!!!!!!

[BloodHuman3]

This will teach you the true meaning of "Big"

[KPuBETKA]

There are no meaning of "BIG" in universe scale.

[PhillipThunderGrunge]

Look at how inferior our own gigantic sun is compared to Canis Majoris....

this is very reminescent of "The Pale Blue Dot"..

[mrblink1823]

wots the VY stand for?

[cassiopeiaproject]

The designation VY means that it is a variable star.

[mrblink1823]

and wots a variable star? lol

[cassiopeiaproject]

The apparent brightness of variable stars (as seen from earth) changes over time.

[AtheistThatsATheist]

I love this video. Ive seen the one NASA put out and a few other simular ones. Youve done a great job.

Looking at the size of VY Canis Majoris and thinking about the gravitational pull makes me wonder if there are stars circling it.

I mean look at our galaxy. The moon orbits us, and we orbit the Sun.

Would it be possible to then have our Sun orbiting another sun, which in turn orbits another? Probability would say yes would it not?

Then what would be the maximun possible chain?

[cassiopeiaproject]

There are countless examples of multiple star systems. In a binary or two-star system, both stars revolve around their combined center-of-mass. And this is true of star systems with higher numbers of stars -- they all revolve around the common center of mass. Ultimately, star clusters and galaxies are multiple star systems revolving around their center of mass.

[AtheistThatsATheist]

Oh god i wasnt even thinking of a Binary system. Of course. I was just letting my imagination run away with itself last night. A moon which circles a planet, which circles a star, which circles another star, that circles a star circling a final big VY Canis kind of star.

But i wasnt thinking of stars revolving round their combined centre of mass, but rather a set up simular to ours. After all what chance does our sun have compared with VY Canis Majoris? So a Jupitor to Sun ratio to be the max

[cassiopeiaproject]

Note of course that even planet-sun systems or moon-planet systems orbit their common center of mass. Also note that VY Canis Majoris has a mass only 30-40 times the mass of our sun even though its radius is a couple thousand times that or our sun.

[YesHeLives]

Hey how can VY Canis Majoris have only 30-40 times the mass of our sun when VY is so much larger? I don't believe that.

[cassiopeiaproject]

@YesHeLives Density is the answer. Just like a room-sized piece of styrofoam doesn't weigh as much as a steel bowling ball.

[YesHeLives]

But that doesn't make sense to me. If VY Canis has only 40 times the mass of the sun it should just expand and dissipate into space because the matter throught the star would be too thin to have a strong enough gravity to hold back the violently radiating plasma. These stars burn brightly you know and have a short life span. So their matter must be very hot and intense and powerfully trying to burst away from the core of the star.

[DaleHusband]

@YesHeLives Well, that does eventually happen when a star goes supernova.

[YesHeLives]

@DaleHusband If VY Canis Majoris is about10 billlion times the volume of the sun (which it is) and if its about 40 times the mass of the sun (which many claim it is) it's practically a supernova already. I don't see how it could hold itself together with that kind of thin density.

[YesHeLives]

@DaleHusband Because I'm not a scientist myself, I'll just give up and go along with the popular scientific belief that these imposing stars are basically just a ball of heat that's probably as dense than the earth's atmosphere 200 miles above the earth. My opinions don't count anyway.

[empyrionin]

@YesHeLives another example comes from white dwarves. A more massive white hole is usually smaller than a less massive white hole. I suggest you study a little bit of math and astronomy. It's dumbfounding how people challenge scientifical truths based on "nothing" but their own guts. Remember what guts told you when you were three and found out that the earth is flat! Your immediate answer about Australians, when looking at a round earth was: "Daddy/Mommy, why aren't they falling?" Guts fail us.

[YesHeLives]

@empyrionin What are you talking about? I am not trusting my "guts". THE scientific truth that I am trusting is what I have learned from the experts. It is that GRAVITY holds a star together. I know that the VY Canis cannot be as dense as the sun or else its gravity would overcome its expansive force and turn it into a black hole. However, if its gravity is too weak, the star woud just explode or expand away.

[YesHeLives]

@empyrionin If Vy Canis Majoris is merely 40 times the mass of the sun, VY Canis would have a density that is probably as thin as the atmosphere 50 miles above the earth's sea level. That is because I know the facts that VY is about 10 BILLION times the volume of the sun. Try stretching 40 suns into that space and see if you will have enough matter that has the gravity to hold all the super powerful nuclear fusion together.

[empyrionin]

@YesHeLives Well, in order to find the answer to that, you need to do the math. You can't just label something as being false because you think that what you're saying sounds true. That's not science.

Oh, and one more thing. Don't trust a youtube video, and don't trust the precision of our measurements. For all we know, the star might not even be 40 times as massive, it might be 30 times. Or 50. Our instruments are not that good.

[6SpAr6TAN69]

@YesHeLives probably because it' s an extinguished star??

[Dbev1]

@YesHeLives I dont believe it either, VY is 1 million times bigger then our sun.

[Moirera]

@YesHeLives (how can VY Canis Majoris have only 30-40 times the mass of our sun)

You think that's bad? Just last month they found a star that is 265 times the mass of our Sun and was believed to be 320 solar masses when it was younger and hadn't ejected so much mass into space.

GG

[JacktheSmack]

Canis Majoris wont last very long. >:D

[Sk8ronweed16]

largest star is VV cephivi

[rebeccageiger]

WOW! Mind boggling! That is like comparing an ant to an ocean. I also didn't know there was a star called beetle juice.. who named VY1 canis majoris?

[cassiopeiaproject]

Its name is a description of the star itself -- the designation VY means it is a variable star. And the Canis Majoris part is the constellation it resides in -- the big dog or the big dipper.

[Zorgonia]

Ahem, the big dipper is Ursa Major.

[Gumbypotty]

Betelgeuse, not Beetle Juice. ;-)

[AlbiorixGallic]

of course.. "Our small world"

a small planet and problematic!

[AlbiorixGallic]

of course.. "Our small world"

a small planet and problematic!

[1RadicalOne]

This reminds me of FFreeThinker's "Our small world" video.

[hephronss]

friggen cant even watch this cause narrotor sounds gay

[SuperMerlin100]

The human race matters to the universe.

Ya right monotheists just keep on telling your self that.

[PaXx]

Fully agree on that

[MOZZWIGAN]

WOW! We really are just germs compaired to things in space and space its self

[milkywaycenter]

@MOZZWIGAN smaller than germs

[kamehameha548]

@MOZZWIGAN we are not germs we are probably 1/1000000000 of a cell

[amartinez97]

@kamehameha548 more like 1/10000000000 of a molecule.

[snakeguy76]

This video requires a very intellectual "HOLY SHIT!!!"

[rollsthepaul]

Our Sun has the volume to hold one million Earth's. Our black hole, at the middle of The Milky Way, is 2.6 million solar masses. The space in between is the really big thing. The universe is not bigger than we imagine; it is bigger than we can imagine. It will be quite a change, when we move from 3D to 4D. I'm looking forward to it.

[guynamednate]

Cool video, what's up with Rigel? Why is it white and all the others are yellow/orange?

[RyuDarragh]

Size has nothing to do with color. Stars emit black body curve colors where temperature is the dominant effect (that's why you can't have green stars). Some stars are fusing Hydrogen. Some are fusing Hydrogen *and* Helium. Some are fusing Helium. Some are even fusing Carbon. The more heat each process releases, the hotter the star. At 40,000 degrees, the star is Blue. At 4,000 degrees, the star is red. Regardless of size.

[RyuDarragh]

As chijohny5 pointed out, yes, larger stars are more commonly bluer because they can fuse heavier elements. It really depends on the mass of the star and where on it's life cycle it is. Some stars become red giants and aren't very massive, but are very large. Most blue giants do not become red supergiants because they go supernova. Look up "main sequence" in wikipedia for an excellent article on this. Now you'll get the references to "O type star, captain" on Star Trek :P

[photon101203]

no One Knows..there are many theories..

Basicaly its a young star..

its white cause it burns off diffrent Mixtures of gases and plasma

[Zuvie77]

subhanlallah!

[crazybigyo]

lol i'm glad we don't live by that star. it would be hot hot hot . XD

[rv186rs]

If we lived by it we would obviosly be in a pretty far away orbit!

Otherwise we could not live there due to the lack of liquid water.

[crazybigyo]

why don't you think there would be liquid water?

[rv186rs]

To warm = boiling

The logical solution is of course to place the planet further away.

[crazybigyo]

well yea of course we would have to live further away. we would just have to be in the right orbit of the star. perfectly far enough so we don't get burned up and close enough to take the suns warmth, just like earth. remember the orbit is wayy bigger cause the star has a giant mass.

[narutocursemark]

O stars r blue stars just to let u no. The hottest stars. Theres a hot blue star that the perfect distance would be the sun to pluto 11 times around!! Thats how far we would have to be!! O F G K M.

Oh Fine Girl Kiss Me.

[narutocursemark]

Oh I ment to say O B A F G K M

Oh be a fine girl kiss me.

[sinxcosxtanx]

That is really big ;)

[mafarmerga]

how do you spell vy canus majoris?

[VonSchnutze]

Canis

[haggidubious]

Good stuff.

[kasuskasus]

Everything is relative.

[ogirv101]

We're but an infinitesimal speck in the stately Universe, though we all feel giants when we humbly accept our insignificance.
