Pulsars & Neutron Stars

[ova69]

HAHAHA THIS GUY SOUNDS LIKE HE IS READY TO SLEEP!

[Bignadz55]

chuck norris Sucks my dick and my dick is just as big and dense as a plusar

[whitekaminari]

The male narrator sounds like he much rather be playing warcraft than having to explain basic astronomy to noobs.

[infamousgrosso]

Chuck Norris plays ping-pong with these

[Cypher785]

I hate it when ppl in the comments tell us what we just learned I'm not 5 I don't need review

[zekromarts]

watch this show called the univeres it tells you all of the junk people say but more

EPIC!

[stan021]

A neutron star can destroy our earth by x-rays and gamma rays. A such star can have 10^11 Tesla magnetic field which is extremly powerful. This magnetic field contains a very big energy which can be released within several seconds and can destroy our earth. What do you think about it?

[l3oss2u]

@stan021 pictures or it didn't happen.

[bfmvshinigami]

Doesn't thing thing defy Newtonian concept of Gravity?

[NAguisrt]

I ♥ Neutron Stars!!

[arkady714]

The explanation of the collapsing star, its density and why it is composed of neutrons is excellent. But I remember their being a reason as to why the light emitted pulsates. This was not fully touched upon in this vid. Never the less, it was a good lesson. Thank you for the upload.

[AlienshateU]

This neutron star light house theory no longer can explain all the pulse drifting, pulse nulling, pulse quantization, pulse phase memory, and mode switching and memory ("grammar") observed in pulsars like PSR 0031-07 ; PSR 1237 +25 ; PSR 0329 +54 ; PSR 1822 -09 ; PSR 1133 +16 ; etc...

In other words the ET communication network is back and will be told to the public when SETI pretends to change focus from shortband song of hydrogen to complicated broadband synchrotron messaging...

[kazmageddon2]

the mumbling dude is annoying

[IAreCandyLand]

..however u spell tht!

[IAreCandyLand]

I LOVE THIS GUYS ENTHUSIASM!!!

[Hontaish]

Lol @ that guy's voice.

[QBisbest]

Wow, that guy sounds enthralled.

[waltercelario]

Greetings from outer space!!! In my galaxy, we have plenty of neutron stars. Oh, i forgot. We'll be invading your planet next week. See ya!!

[istewartbinks]

To be fair everyone, the scientific revolution molded Natural Philosophy and Mathematics together, AKA Science. @HRage, even though i do not believe that religion 'started science (?)', your argument is only ad hominem and puts no claims forward. I suggest you learn how to put an argument together and then try to make your claim again.

[JambaB]

Interesting but that male voice is most boring voice i have ever heard

[powerfulwords]

Good explanation, thanks

[MrAwesomesauce101]

Why do I see a science video and look at the comments and see religious nuts or perverts in a video about astronomy every time! What has this world come to?

[denmak]

The guy reciting this has a voice that makes Disney fucking land sound like a morgue...geez!

[2012thedevil]

@denmak He sounds like Pedro from Napolion Dynamite...Could not understand a fucking word he said.

[MrAwesomesauce101]

There's a system a pulsar star near bye that has 2 planets there probably not habitable considering it's a neutron star.

[MadeinHell2]

Wait did I hear that right? Neutron stars rotate 700 TIMES per second? O_O

[wo0obly]

@12000orbits there is no star 1000000times more massive than our sun that we know of :)

[TheSerpentoftheSky]

@wo0obly yes but remember we only know roughly about 0.000000001% of the universe

[wo0obly]

@TheSerpentoftheSky thats why i said what we KNOW of lol

[MegaRoFLL]

@wo0obly vy canis majoris , check that out.

[wo0obly]

@MegaRoFLL that is NOT 1000000 time more massive. your saying theres a star with a diamiter of 1000000 x 1000000? thats 1000000000000miles -.-

[supafly1983]

@MegaRoFLL Speaking of VY Canis Majoris, while it may hold the current record of largest star discovered, it is only in diamiter. In terms of mass, There is a blue hypergiant called R136a1 which is estimated at 265 - 300 Solar Masses, and with surfice temperatures of 40,000 degrees Kelvin! Imagine when that thing pops it top.

[Thevideoclown]

great explanation for my exam soon. thanks

[TimpBizkit]

Chuck Norris could do a one arm push up on the star surface....

[dravidr007]

prof cox.....ty!

[63gstone]

"reaching new heights for 'women?' x-ray astronomy? Is that wat she says?

[RaytownSoClassof2010]

If a civilization some how adapted and survived on a neutron star with gravity 100,000,000,000 times our they would be equal in strength to superman after he sun dipped.

[Marine5484]

I just had a flashback of 7th grade and what does this and the koran have to do with anything you can claim in the bible that god saying let there be light was the big bang so please don't inject religion with this...of course I probably blew some stoners mind lol

[wormhole199]

@Marine5484

The Bible said "Let there be light?". Really? Well after the Big Bang photons couldn't travel at all. For the first 300,000 years the universe was opaque (non-transparent for visible light). After the universe cooled it became transparent. For other wavelengths it was opaque for a billion years. See: news.discovery.xxx/space/peeki­ng-at-the-edge-of-the-creation­-of-galaxies.html (replace the xxx with com).

So "Let there be light" turned out to be utter crap.

[Marine5484]

@wormhole199 dude it was just a theory calm the hell down i was simply stating that you can take verses from many religions and apply it to many many aspects that we experience and i know the early universe was more opaque gas then anything it took a long time for that gas to condense into hot gas then finally stars

[EnclaveRobloxTV]

AKA white dwarf

[JD3K]

@EnclaveRobloxTV not the same thing

[msalameh01]

Many Thanks for Nasa and colleges for these science discoveries, because it proves the scientefic parts of Holly Quran, it is mentioned in Quaran, that the sound of knocking in sky from the star of Piercing Brightness (it pierces the silence of the sky by Knocking), subhan allah, there is no God (Allah) but him only, and no other God. thanks all.

[nsG0]

fucking hell, most enoying voice of the guy. cmon don't be such a whiny bitch seriously

[irkiIIer]

chuck noriss plays soccer with it

[ChRIs23696]

@irkiIIer no, chuck norris plays FOOTBALL with it

[gpgpgp13322]

@ChRIs23696 lol thats better

[MxC1337MxCsh43d]

@ChRIs23696

Chuck Norris wouldn't call soccer "Football" because he's not a faggot.

[Ace0077]

@MxC1337MxCsh43d

what are you on about retarded yankee, you faggots stole the name "football" for your gay game

and I'm not even english lol

[MxC1337MxCsh43d]

@Ace0077

Football's manier then whatever faggotry you're "on about", fucktard.

[FIGHTFANNERD3]

@ChRIs23696 both of you shut the fuck up

[01101111omg]

@ChRIs23696 Chuck Norris plays FUCK with it...

[WeaselWJ]

@ChRIs23696 Does it really matter? They are synonyms.

[jeremalaria]

@ChRIs23696 chuck norris, being american, plays soccer with it. 

[ChRIs23696]

@jeremalaria well the sport, being english you cocky bastard, is called football.

[enjoixander]

My left nut is a neutron star.

[TheFffoithegreat]

@enjoixander Gay.

[Ievolovel]

@irkiIIer Fuck chuck... Bruce kicked his ass.

[EatShiteAholes]

@irkiIIer

and, chuck norris can juggle neutron stars...

[gobuddyboy]

Quran told us what a pulsar sounds like 1400 years ago.

[OmegaDude22]

Wait, how do you get a magnetic field from a ball of neutrons? :/

[meteor4163]

@OmegaDude22 I think it's because it's positively charged and it's spinning fast, making the effect of a current loop that's generating the magnetic field.

[rnrbishop]

@OmegaDude22 because it spins REAALLLLY quick!

[Dekoomer]

if you was to teleport at the surface of a Pulsar for .0000000000001 of a second and teleport back to earth, 1 of two things will happen

1. you'll return as the invisible man *wink*

2. will explode

[LaughsWontHurt]

Neutron Star - It has such a density, that if you had 1cm3 it would weigh as much as all the cars in the US.

[Kincajou]

Why is it that science vids always get these religious nuts?

[intheshitter]

@Kincajou They all seem to hate science for some reason yet the computers they use are based on these crazy theories that scientists supposedly make up.

[Kincajou]

@intheshitter

Exactly. You'd think allah and muhamad would've tossed them a computer er two.

[Tatskumi]

@Kincajou i dont know honestly. Its almost like they love to ruin the video for us by getting overly religious about it. I may be a Christian, but i dont go preaching my religion in a video blog just to try to make a point. Enjoy the video & leave religion out of it. Just watch, not that hard to understand.

[alitou001]

@Tatskumi religion is the base of science , because of the religion how everything started . read the Holy Coran and see how many scientific facts are there .

[HRage]

@alitou001 your atrocious articulation alone is a very good reason for any sane person to avoid the koran as a source for science. Why not learn how to put a sentence together (Sesame Street is good for this) and then make your claim again.

[alitou001]

@HRage language is not science ,its literature ...

[intheshitter]

@jsalex17 Good for you!

[Tatskumi]

@jsalex17 OOOOOOOOOOOOOOOooooooooooookaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaayy­yyyyyyyyyyyyyyyyyyyyyy . . . . whatever.

[iycgtptyarvg]

Is the commentator on drugs? Man, he sounds like he's depressed or something.

Good video and explanation though.

[MasterTJ007]

DESTROY the narrators!

[BluebluredX]

The narrator sounds like hes dying and has strep throat. Could barely grasp what he was saying

[richcoolerearth]

Stephen Hawking could do a better narration.

[Oxyster7]

it's really hard to hear him as he mumbles and they put that annoying music in the background.

[DuxBellorum87]

Star that's 10 to 20 times more massive than our Sun can explode as type-II supernova, so the neutron star is a remnant of this tremendous disaster, such as Calvera, Geminga, PSR 1257+12 (old neutron stars) and Crab Pulsar (a young neutron star).

[MrSirSmoky]

Aaaaaaaaa!!! Those narrators are so... BORING!!!! Wake UP!!!

[lordieuan777]

@MrSirSmoky You gotta bear in mind, for lots of the people who narrate these videos, English won't be their first language. It's difficult to add inflection and emotion into a language that isn't your own unless you are truly immersed in it.

[jimnorcal1]

Wow. Could they have picked anyone more boring than these two to narrate this video? They were so monotone and failed to properly annunciate their words that it was actually painful to listen to this video. I could have done a better job than these two. Of course where were they going to find an exciting sounding scientist (expert on neutron stars/pulsars)?

[mrdenisfly]

@jimnorcal1 haters guna hate :S i found th video very informative

[jimnorcal1]

@mrdenisfly Huh. That doesn't sound like something I'd say. That's surprises even me. I retract my statement assuming I said that. I must have but like I said ... it doesn't sound like something I'd say. I'm more grown up than that. Oh well. It's done.

[tommyk77]

The fastest spinning Neutron star now is one that is spinning at 1022Hz!

That narrator has the most dull voice I've ever heard

[Dahibd1]

BOOBIES

[azafhl]

@Dahibd1 tits

[bitchslaughterer]

I have a question... They say that most elements that make planets and us, etc. are the result of supernovas. A supernova will always have a neutron star. If this is the case, then where is the neutron star from the supernova that made all the matter in our solar system?

[MaraudingMaster]

@bitchslaughterer

The solar system wasn't formed from a supernova. I think it was formed from a cloud or something.

[bitchslaughterer]

Nope, Most of the matter in the planets (99% of the matter) are heavy elements. The sun and other stars only burn with enough energy to convert hydrogen to helium. It is only when a star dies (in a supernova) that there is enough energy to create the heavy elements. And yes, we were formed from a cloud... A cloud of heavy elements from a dead star.

[friedpootatoos]

@MaraudingMaster

The molecular cloud from which our solar system condensed was comprised of material ejected by primitive colossal stars that formed in the early universe, when most of space was filled with hydrogen. They had tremendous amounts of available fuel, grew to stupendous size, burned very hot and lived short lives. It is likely that almost all of these erupted in supernovae. Some became enormous black holes, which may have aggregated into galactic cores.

[Helge129]

That is not entirely true, all the matter is made due to nuclar fusion, hydrogen to helium, etc.

In a super nova, also in wolf rayet star, a big ammount of that matter is jettisoned into space. Some supernovas leave behind a nebula, a black hole, or a neutron star.

[friedpootatoos]

I think you mean all elements heavier than hydrogen - the particles that nuclear matter is made of originate from a time before stars.

[TehYTP]

Every supernova does not leave a neutron star. There are many types of supernovae, which leave black holes or other things. And it may be matter from the Big Bang that formed our solar system, not a star exploding.

[friedpootatoos]

Just because our material came from supernova doesn't necessarily mean we are anywhere near it's originating point. Ejected materials can travel vast distances when you have that kind of energy.

[laserfloyd]

Sometimes supernovas leave behind a black hole as well. I suppose that in the early Universe the stars were vastly larger and lived short lives. They exploded and ejected the heavier elements all around. As the Universe aged smaller stars with longer lives came about. We fall into that category. Don't quote me though :)

[doctornouna]

I do now believe that Muhammed is telling us the truth, and that he's the messenger of The world's creator, ALLAH.

[IslamAyaat]

Amazing how this this harvard university student says these stars are called pulsers. Prophet Muhammad knew this 1400 years ago the from the Quran.

1- By the heavens and The pulser.

2- How will you comprehend what the The pulser is?

3- Its a piercing star.

86-The pulser, 1-3

[Lucas6194]

I just discovered one of these, youngest person to ever discover one ^_^

[serfaksan]

congratulations :)

[Lucas6194]

Thank you :)  They're doing the interview early september.

[BCSpore]

Congrats!

[Lucas6194]

Thank you :D

[channysherly]

Neutron stars - a single teaspoon of thier matter weighs several million tons. Plus, they can't be larger than 20 miles across due to thier rotating speed. They rotate at over 100 times per second and the PSR J1748-2446ad rotates at 716 times per second.

[t4c03]

well the neutron magnatar is one of my favorites i think that they start off at a magnatar and form on to a pulsar later on like 1000 2000 years old

[mixshorty222]

pulsar's are very very dense making them extremely heavy

[Deanoshea23]

No shit sherlock.

[12000orbits]

Your star (or sun) is 1,000,000 times more massive than our sun. But stars in that mass range do not end up as pulsars! Their remnants directly collapse into black holes!

[joab321]

@12000orbits million solar mass do not exist. Pressure can not go as high as to support that kind of star.

[TheHeho]

@joab321 yeah, only supermassive black hole can be millions or billions solar mass

[NeutralNegotiator]

@12000orbits once upon a time people believed that earth is flat. Our knowledge is only based on our senses and the means we have to enhance them(like telescopes). Everything we know so far about things beyond our solar system are assumtions, but NOTHING has yet been proved. We still have a lot way to go. Keep your mind open in any case that anyone proposes

[Rolandhinio]

@12000orbits

It starts from approximately 100 Sun masses to whatever's more than that :)

[pigbigtig]

Can someone send me the formula to this exercise:

The mass of the Sun is 2x10 on 30 kg, period of the Suns rotation is 25,46 days and the radius is 14x10 on 8 meters. What is the radius and the period of rotation if the Sun transforms into a pulsar?

Pls send me the answer and the formulas with which you came to that answer.

[piccleman016]

Sol (our sun) wouldn't transform into a pulsar- it's far too small. it was just turn into a white dwarf, and eventualy just burn out, perhaps (worst case scenario), it might eject it's outer layers, causing a nebule, that's not gooing to happen for millions of years though, so dont worry =)

[mikeberserkr]

Food for thought:

The "EARTHQUAKE" that caused the tsunami was very terryfying...

However, when the earth is at least 10 LIGHTYEARS AWAY, (yes, 10 years traveling in the speed of light)

The "wave" from the STARQUAKE of a Magnetar of this magnitude CAN END ALL LIFE ON EARTH..

even from 10 light years away

AND

The magnetar starquake released more energy in one-tenth of a second (1.3×1039 J) than our sun has released in 100,000 years

its that powerful...

[danisoyyo]

how?

[Penguinz13989]

to dbz4e:

yeh, I can also finally tell people there's proof that flying monkeys fly out of my ass.

[abdu123]

Lol when pulsars were first seen, scientist thought they were signal beacons from aliens because of how exact the pulses were. It was 2 times every second consistently.

[docvij]

hmmmmm

[lepape2]

Very interesting!
