- The magnetic field of a newly found ultra-rare neutron star is over a trillion times greater than Earth's. So powerful, if you were within 1000km of this star you'd simply dissolve! Should we be worried?

Just a small correction: The Earth magnetic field is around 50 µT, not 1 µT
Thumbs up to the narrator. She adds emotion to the phenomenon, which is a good attribute when talking astronomy to them that don't know.
she's not just narrator who reads script, she has PhD in Oxford's astrophysics. Also - she's Dr Josie Peters
@@mroutcast8515 she must be someone working for the BBC. Great video altogether. Love the information and art rendering.
she was magnetic to listen to! 😊
@@mroutcast8515 Are you for real?
@@MsKTMvalley It was a well packaged piece.
I dated a magnetar once, you won't believe how attractive she was.
I can't believe you've done this.
@@Pauly421 You're Just Jealous.
Oh wow! Out of sheer curiosity - which dating system did you use?
Excellent video !!! Really well simply explained with good mix of animation.
My 2nd Earth Lab vid. So glad I subbed - this was really interesting and very well explained by presenter. Loved that marsh mallow metaphor. Many thanks.
A Magnetic presentation
I love seeing these videos late at night just before bed. Makes me think about all the unknown!
Stranger than fiction!!!! Amazing
Still won't hold onto my fridge
lol
1:07 Small correction there: Earth's magnetic field goes from 25 µT to 65 µT (not 1 µT) 🙂🌎🧲
First time I heard neutron star pulse with the video.. Astonishing.
Fascinating stuff!
Thanks for acknowledging that we actually don't know many things.
The sound was impressive
Incredible.
For a moment I thought the narrator was Emma Stone
Crazy to think all that mass of a star compressed to a size 20km in diameter. Then you realize something is MORE DENSE than this!
I love the 'maybe one day it's secrets may be revealed'. You can take my place in the space ship, and safe travels.... eeeer, not.
Now, THIS is an interesting discovery.
I thought magnetars and pulsars were two different types of neutron star? I didn't think one could be classified as both??
I think it's kinda like every Pulsar is a Magnetar but not every Magentar is a Pulsar...
Pulsars are magnetars that are spinning and have their poles pointed at earth so we see the pulse. The poles constant spew out more radiation (particles of matter and light) because of that magentic field pushing them along the pole. When that beam sweeps over us, it looks like a pulse!
I've wanted to disappear my whole life. This sounds like a dream come true.
😀 Really amazing !!!
My dad had an inbuilt sense of magnetism, a bit like a pigeon. You could blindfold him, spin him around and he would still know where the direction of north was. Great video.
Your dad might be a pigeon.
@@preciouscartoons3424 He did use a lot of Dove soap, so you may have a point.
Simply The Best!
So a... Magnetar?
beat me to it but yeah the title would have to be renamed to second strongest magnet out there magnetars are wayyyyy stronger than neutron stars O.o only second to a black hole
@@gamerelite3989 magnetars are a type of neutron star
@@alwaysdisputin9930 well yes and no if you research a bit magnetars are born like this until they ( become ) a neutron star ( or pulsar ) later on when they lose magnetic strengh i dont remember how long but it should be around 100k years then they decay into neutron stars so yes and no imo but the subject is open largely to debate as most of it is theoratical to this day :) cheers
@@gamerelite3989 How can a magnetar "become a neutron star" when it already is a type of neutron star?
What happens if a Magnatar gets to the event horizon of a black hole, does the black hole have more power than the Magnatar and tear it apart?
It's not even close. The black hole will eventually eat it. The density of black holes at their center are infinitely more than neutron stars. Nothing warps reality and is completely inescapable like a black hole.
Neutron stars still play by the rules of our universe. Black holes are a kind of tear in it, so extreme that very different rules apply. Where the gravity of a neutron star would slow time, a black hole will stop it. Whoooole different ballgame.
Search black hole neutral star merger for a simulation animation.
One thing that kind of freaks me out is, when two neutron stars collide, I imagine that lots of debris breaks off the stars and escapes the system entirely (some at relativistic speeds). I also imagine that some of these chunks of debris aren't exactly microscopic either. So there are almost certainly baseball side chunks of degenerate matter that weigh as much as a small moon or more randomly careening through our galaxy at speeds that make the asteroids we are accustomed in our own system to look like they are moving at a snail's pace in comparison (and that is being generous). We still have a hard time detecting asteroids in our own system that are a 100 meters across and only going 100 km/s. So one of these neutron star chunks could just absolutely blind side us out of existence.
Neutron star matter can only be that way when under extreme pressure. That sugar cube of neutron star the presenter hypothesized would very rapidly explode into protons and electrons and further explode due to EM repulsion. That sugar cube would explode with megaton energies. Similarly those bits of neutron stars after a collision would decompose into protons and electrons but, of course, moving outward at relativistic speeds.
How I know, this is how the rare metals were made. The last possible product of atomic fusion in stars are iron, elements which's nucleus is more massive than iron were created after the collision. The degenerate matter will form these massive nuclei and they will or will not start to radioactievly decay producing more and more diverse elements.
I don’t know how plausible that would be, it seems certain degenerate matter can only exist as such under extreme conditions and I don’t know how big of a gravity well or a temperature would be needed to hence how possible chunks are, but knowing the star is a mere 20km in diameter makes you think it sits at the edge of gravity, so anything smaller would plop out into unconstrained or less constrained matter.
The only thing I do know for sure is people are still killing eachother (or better said letting their own people kill en be killed) for in part for the stuff that is killing our planet. The best part of all our money, wich we too contribute to through wages and taxes (as opposed to really rich people) is still used to make war with ourselves.. if all those dabloons and euros and yengs and roebels and al the resources, physical or intellectual, could be joined in cooperation we would have a slim chance of colonizing the universe, and maybe in pole position too. But alas I’d guess chances we are doomed currently are higher. I mean the fact that trump could be a serious candidate for next presidency (every hour he is president the human race loses a month or year of progress), the fact that putin has completely lost it, .. we are even competing eachother for resources IN SPACE!!! Bunch of incompetent irresponsible narcistic devils, who if humanity will prevail will always be remembered as the worst humans ever lived and always despised. Everyone of us probably, we are the infancy of humanity, we have the means and the knowledge and resources, but the only thing we are accomplishing is killing all current life and all future life
I wonder in what feature film such a regular beat of the radio signal of a pulsar may occur. It certainly would make for a good effect.
When those pulses were first heard they were dubbed LGM, for Little Green Men before the pulsar mechanism was theorized.
great!!!!
This isn't even my final form.
I'm not sure if the numbers add up. Earth's magnetic field is 1/1,000,000T and the magnetar is 1,000,000,000T. It sounds stronger than one trillion times stronger than the Earth.
Yeah, it should be 1 quadrillion and not 1 trillion times stronger than Earth's magnetic field, if this data is correct
🤯 mind blown when she said up 700 times per second. The universe always seems to go beyond comprehension.
4:40 Why isn't this animation giving the impression that it's swirling around, thousands of times a second?
Before you got that close you would just fry
My crush is like this neutron star to me.. i dissolve when i come near her..
Narrator needs a raise, she's good
Mind boggling
Your gravitational pull is stronger than a billion suns, your magnetism captivating like a magnetar. In your eyes, I see the spark of a Tesla, and in your presence, I am awestruck like gazing upon a neutron star.
Sooooo, if I need my computer to be wiped clean I send to this ?
When that lady discovered pulsars, men took the credit for her discovery & won the Nobel prize unfairly.
a star like has it's own classification even though its a neutron star it's classified as a magnetar
Largest -we have found- in the -observable- universe
How to record that pulsar cp 1919 sound?
1200 Tesla to blow up a science experiment? You should see me with some tinfoil and a microwave. Jk. SCIENCE!!!!
This made me think, neutron stars are basically not quite black holes?
What dissipates the magnetic field entirely?
It’s an “almost a black hole.” They have to have a solar mass < 3 in order to not collapse further to form a black hole
The problem is that only moving charges create by field but as said they are full of neutrons, by b=ila, but i=0 so b=0, so q=o cants have any electric or magnetic field anyways a wonder
The stars secret will never be revealed
I have a question, two actually, what are the difference between magnetic and gravity ? and how those field can vaporize our moleculs ? Thanks in advance.
There's a electromagentism play list by Science Asylum that does a GREAT job explaining!
A taste: Magnetism is half of the electromagnetic force. Every time electricity moves, a magentic field is made. The photon is the particle that carried the electromagentic force, which, depending how fast it's wavelength, can make radio waves, microwaves, infrared radiation (what heat vision sees) , light, x-rays, and gamma rays.
Gravity is a warping of spacetime, and is very different. For one, it's way WAY weaker. The electrical bonds in a sheet of paper can resist the gravity pull of an entire planet. A tiny fridge magnet can overcome the pull of the entire earth. But magnetism doesn't affect the flow of time like gravity does! The more gravity in a spot, the slower time runs in that spot! For instance, people on earth experience time slower than sattilites and astronauts.
02:17 wait, aren't black holes denser?
Even stevens. B Holes stretch you out in to spaghetti before vaporizing you, neutrons just instantly vaporize, without going to the restaurant first.
Yes, black holes have infinite density according to our best math (though we suspect the formulas are incomplete as we haven't figured out a unified theory of everything aka quantum gravity).
That said, black holes are also kinda no longer part of our universe, at least the singularity in the center where all the matter is, so you could argue she's still technically right.
Even with such an attraction, it's still repulsed by my affection :(
I love your videos! Haven’t seen one in a while. But why are YOU so magnetic? 😄
Shoot your shot yeah..
❤
Marshmallow go *BURRRRR*
This type of video's deserve atleast 10k likes . It takes a lot of time and hard work to make a video like this❤.
Passion anew! Thank you and compliments to this young lady.
How do they know they have strong magnetic fields? Does the magnetic field interact with light
I’m no expert, but I’m pretty sure it’s got something to do with the measure and strength of radiation being emitted from the star.
Magnetism is tightly knitted in the physics of light, since we measure light/radiation on the _electromagnetic spectrum._
Such an intensely strong, continuous electromagnetic pulse of x-rays or gamma rays would be emitted that it could be concluded that it is a highly magnetic object.
Yes gravity interacts with light - gravitational lens effect
@Enneamorph interesting so I guess If the object is really small and it's emitting lots of gamma/xray radiation then we can calculate the strength of the magnetic field
@@Luappy13 strong magentic fields can also polarize light
Sometimes I just can't believe that these things are out there, and I'm right here. Crazy!
We are like the ants who have no idea elementary chemistry
The strongest in the universe? Have we advanced so far we really know that?
Obligatory "props to the traveling cameraman" comment
Shouldn't they be referred as stellar remnants instead of stars maybe?!
Great video as usual though 👍
theyre still functionally the same as stars
@@womp47 Quite literally not the same functionally.
@womp47 I don't think so. They are literally no longer a "Star" since the "Star" is "dead"
@@womp47 I agree only to the extent that I completely disagree.
Earth’s magnetic field is due to its iron core.. so then that neutron star may also has a iron core…
Iron just doesn't cut it I'm afraid. It's like a grain of sand compared to a supertanker.
The neutron star is made of neutrons! Like, it's so heavy, it pressed the electrons into the protons making the neutrons. Nothing but neutrons (and possibly strange matter) can exist in that extreme gravity!
It's kind of like the neutron star is on giant atomic core.
How was this star discovered if it's so powerful?
ummm wut
@@coconutsmarties it's a simple question.
@@Ozjoker420. But one that doesn't make sense. Why would a star being more powerful make it harder to detect? The opposite is more likely to be true
@@coconutsmarties how was it detected?... its a simple question.
@@coconutsmarties from how far away was this star detected if it so powerful and destroys everything to nothing.. was it the JWST from q certain distance?... it's not a hard question.
What would happen if a Neutron Star was to encounter a Black Hole?
They're called black hole neutron star mergers. The neutron star orbits the black hole at first, getting closer and closer. Once it's close enough, the gravity starts ripping off part of the neutron stars matter into a disk around the black hole. As they get close to merging, they orbit each other so fast that they send out ripples in space-time that we can detect. Then the black hole eats the neutron star, absorbing its mass, angular momentum, and Magnetism. Some of the mass doesn't make it in, instead getting shot off of the poles at incredible speeds. As neutron matter comes apart in these incrediblely powerful particle beams, thanks to no longer being crushed together by the star's gravity, it makes a huge range of heavy elements that rapidly breakdown into smaller, more stable but heavy elements.
It's awesome, basically. You cna look up simulations of them if you want to "see" one.
@@psalmy26 Thanks as I'd assume there would be some gigantic matter related explosions of some sort.
I think you'd be in some trouble being 1000km from ANY neutron star. Also what the hell is happening in that video??? What exploded and why? You just not going to tell us? Bah!
Yeah I was wondering that too. I mean she's hot and all but I want better information
She looks like Emma Stone😁
Didn't veritasium cover magnetism recently?
Yes, that was a 45 Tesla machine. He said i's the most powerful magnetic field on Earth. But in this video, they showed one at 1200 Tesla inside the room causing explosion. Kinda confusing.
@@prakash_77 The 45 T facility is the best we can keep running continuously. We can go higher than that, but only for short periods of time since the equipment creating such strong fields basically gets destroyed by it - exactly as seen in the video.
@@Ylts92 Thanks for elaborating.
Failed Blackholes
isn't this becky evans?
It's been my understanding that magnetars are the angry infant version of newly formed neutron stars. The magnetar comes first, eventually calming down into a regular neutron star. Two neutron stars colliding would cause a black hole in most scenarios, not a magnetar. I don't think you got that part right.
I was thinking the same thing
Yeah this video got a lot wrong, which is odd. Isn't she like a professor or something? I guess its possible she's just a presenter who reads a script but doesn't really know much, idk.
@@Simp_Zone She has an astronomy degree.
🤔😁👍🏻
Good video. That's what separates a true scientist from you tube star who just want to create sensation. Scientist humbly tells what many things we don't know and avoids unnecessary hype and sensation...
She looks like a British version of Emma stone
if you get close to this star can you seperate the nuclear enveloppe of an atom? if yes, can you add a new molecule to the atom and close the envelope? can you contain light?
all of this is really interesting, new elements could be create because of the intense magnetic pulse, or could be containned for billion of years
All the protons have electrons pressed into them by gravity, converting them to neutrons, and then all the neutrons are pressed into each other so it's kind of like one giant atomic core. Except the neutrons aren't perfectly evely connected, they make shapes like pasta (spaghetti, lasagna, etc). You can look up neutron pasta!
When 2 neutron stars merge, part of the neutron matter is blown off. Free from the gravity electrons and protons can separate once again and it starts becoming many kinds of heavy metals as it breaks apart. These heavy metals further divide until they become more stable. Most gold in the universe is made this way.
Owo !
Neutron Star: I am the strongest magnet in the universe.
Black hole: then what am I ? Not even light can escape me.
Le Tesla: naam kaafi he Mera.
This just shows to me more evidence that God is laughing at us trying to understand the Universe.
Which God?
@@psalmy26 The Great Spirit. Yahweh. Allah. All the same. God is God. Eternal.
Imagine preaching bs under a science video.
1000km is incredibly close, you’re basically on the star. Your statement has little meaning
You would disintegrate anyway
Exactly. Neutron star or stellar black hole if you're within 1000km you're toast regardless.
Viewed from 1000 km away, a neutron star ~20 km across would appear just about twice the apparent diameter of the Sun as seen from Earth.
U r beautiful.

Y'all got to believe that God who created all things
never heard of that
god isnt real my man, you dont have to believe everything a random book from thousands of years ago tells you
No such thing as God, or the devil.
@@Ozjoker420. On this we agree..
@@Ozjoker420. you want some proves take a look around how did it came .. look at your self how your body is perfectly designed what if you had one hand or what if your eye was in your legs etc . There got to be someone who created everything..justlike your phone was created by somebody it didn't came by itself or evolved it self.so if you believe you phone was created by somebody.then you should also believe that all things stars ,human animal, plants etc are created by god cause they are far more complex and perfectly designed things than a phone .
What is that thing at 3:02?
Imagine being a Dr. and only doing YT 😂😂
If Earth's magneticv field is a millionth of a Tesla and this star's magnetic field strength is a billion Tesla, then it's 1 quadrillion times stronger than Earth's magnetic field, not 1 trillion
rather not see the person talking ruins the immmerson haha
