- This artist’s impression video shows how two tiny but very dense neutron stars merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short gamma-ray burst, both of which were observed on 17 August 2017 by LIGO-Virgo and Fermi/INTEGRAL respectively. Subsequent detailed observations with many ESO telescopes have confirmed that this object, seen in the galaxy NGC 4993 about 130 million light-years from the Earth, is indeed a kilonova. Such objects are the main source of very heavy chemical elements, such as gold and platinum in the Universe.

nice song and animation...such a beatiful Kilonova!
Won't be so beautiful if you were next to it. 🙂

Two neutron stars merging is the birth of a black hole and the kilonova creates gold
No it makes a new star
@@doge151. No, it also creates gold and other heavier elements by merging and fusing together.
If the merger liberates enormous amounts of neutrons and heavy elements form by neutron capture, can you find super-heavy elements by spectroscopy near the kilonova, that are not known on Earth? Please find out and dissipate the information. Thank you very much for the video.

I have to say probably not, because almost every element with higher atomic mass than uranium (thus heavier than it) is man-made, and is unstable, decaying quickly into lighter elements, alpha particles and other forms of radioactivity. We may find rare isotopes or maybe discover new ones, but, as I said, heavier elements are unstable, due to eletromagnetic repulsion, between protons, and tend to decay pretty quickly. There is a hypothetical "stability island" where superheavy elements could become stable through achieving an interesting form, called "bubble configuration", but, as the name suggest, it is hypothetical, and we are yet to see it. Studies point that as we aproach 184 neutrons on the nucleus, the atom tends to become more stable, raising it's lifetime, but we are having a hard time getting there, as we are, atm, at 175 neutrons, on the heaviest element ever made (Oganesson).
BUT, if we are to discover superheavy and stable elements, it would be near fusing neutron stars :)
@@victorfonseca5561 The element on stability island would still decay incredibly rapidly though, probably with a half-life in the order of milliseconds, so we'd never be able to find it naturally. There's a chance we could artificially create it though, and then let it decay in order to discover some of the lighter, less stable elements below it.
@@Oliver-wv4bd actually you are wrong: elements we create artificially are unstable because they have wrong neutron-proton ratio because of limitations of technology that we use.
And we in fact did found traces of decay of heavier elements in stellar objects that strongly imply that such elements are created however they are not as stable as i.e. uranium. But stable enough to have half-life measured in at least thousands of years and not in milliseconds.
I am in love with it ❤️
Today I heard the term kilonova for the first time
That's pretty cool
So satisfying
Can I have the rights to use this video in my video I will give you guys credit in the description
It should make a black hole. Because they will form a singularity after coliding with eachother.
Very Beautiful - God Bless you for this ✨
I strongly disagree with how perfectly well the stars each keep shape while their velocity increases, seemingly exponentially, as the distance between them gets smaller and smaller. Would they not experience any loss or transfer of visible matter at least from the outer most shell just prior to the collision? I understand the density of neutron stars is unimaginable, but with that density brings equally unfathomable gravitational affects. I hope I’m wrong and this is truly a 100% accurate representation, but I have doubts and just really want to see an accurate model.
Youre right, they would rip apart before colliding. The speed is also misleading as nuetron stars will reach a quarter of the speed of light while rotating to each other
New research suggests the simulation might actually be accurate!
Think of this as "artist's impression ".
The sphere explosion is right, though.
Yeah, this one from NASA shows that a little better. czcams.com/video/IMcU2m5YbFE/video.htmlsi=CDIclwOjlE1tP9R_

While most people worry about where the heavy elements originate from, relativity is no longer just a theory. It is now observed. We have many observations of time dilation due to gravity and now we can confirm having observed distance dilation due to gravity and only just now having been validated by the visible light of a kilanova. Relativity is here to stay. It's not just a theory anymore. Relativity is science fact.
What are the "many observations of time dilation due to gravity" you are referring to? I'd be interested in a list, thanks in advance.
Also, don't you suspect that, if an observer was outside the universe, looking back in, that there would be no gravitational warping of time & no relativity of spontaneity? I don't have conceptional difficult with the warping of space by gravity but can't get my head around the warping of time by gravity or even the concept of the spac-iation of time.
Relativity of time must be simply a 'local' observation, not a grand-universal time phenomenon an you can't have 'effect' pre-dating 'cause' unless its an illusion, or a local-only observation. I'm not even vaguely qualified to challenge Einstein but maybe the array of interpretations of Special Relativity is erroneous.
David Finney , there are two kinds of relativity. Special relativity relates to speed and general relativity is caused by gravity. Time runs faster in space than it does on earth. GPS has to take that into account in order to be accurate. Time dilation due to gravity has been measured many times. Distance dilation has been detected only this past year or so and confirmed by the light from the kilanova a few months ago.
science facts are known as theories
By saying relativity is "no longer just a theory", the only thing you've proven is that you don't know the meaning of "scientific theory" yourself :)
victor fonseca agreed.
I wonder if he would begin calling people who find anything in quantum mechanics, disagreeing with Einstein, "gravity deniers".

Supernova neutron star explosion!
Is it just one neutron star now?
Yes, fusion of two
Possibly a black hole, it shines because of all the remains of the previous two neutron stars
@muhammad al fitra Not necessarily...
Depending on the size of the two neutron stars,they can either merge into a black hole,a magnetar or a bigger neutron star.
@@KirbyUaufixD If it was a black hole,the ejected matter which resulted from the merger should have been pulled back towards the center.
And no,black holes do not shine,they are invisible unless they have an accretion disk.
@@thethunderchieftain5464 a magnetar is a very active neutron star

It’s an explosion of life right? I mean don’t these explosions result in the release of materials which make up the most base foundation of life and in time these materials coalesce to form new stars and planets? The cycle of life is tragically beautiful.
This is what nova can do
Our universe probably began as the merger of two super massive black holes left over from a previous epoc in the manner of the neutron star collision merger shown here.

No, heavier elements!

No a bright star creating a planetary nebula.
What are those blue things around Neutron Stars?
They're gravitational waves, oscillation of the curvature of space-time.
As the neutron stars get closer and closer, they radiate more and more energy away, in the form of gravitational waves, just like when you throw a rock in water, some of its kinetic energy is transmitted to the water, making waves that propagate away from where the rock entered the water.
i used this in my intro lol
where's the black hole?
A black hole is formed after a supernova. Sometimes a neutron star forms instead. When 2 neutron stars collide or when a neutron star and a black hole collide, a kilonova happens
But I might be wrong, I’m still learning
@@squidpile You're right, as far as I can tell, but I'm still gonna try to clarify things a little:
Stars are big plasma spheres, inside which nuclear fusion is occurring, i.e. they are fusing light elements (hydrogen, helium...) into heavier ones (oxygen, carbon, up to iron). This process liberates a lot of energy, that generates radiation pressure, pushing all the matter of the star outwards. So why aren't stars just constantly exploding? Because they have a lot of matter, and that matter has mass. And anything with mass generates gravity, which **attracts** matter.
So stars are in an equilibrium: the radiation pressure generated by the nuclear fusion pushes matter outward, whereas the gravitational pull due to the mass of the star pulls matter inward.
So far, so good.
At some point, the star runs out of matter it can fuse, and dies. At that point, the star is made of several different elements, arranged in onion-like layers: the further in you go, the more massive elements you find: The outermost layer is mostly hydrogen, whereas the core is mostly iron.
Since the star can't fuse matter anymore, it falls out of equilibrium: gravity wins over radiation and the star starts to collapse in on itself.
When the outer layers reach the core, they bounce back outward, and are ejected a great speeds, several thousand kilometres an hour, if I remember correctly.
This event is called a supernova, and only happens for stars much more massive than the sun.
After the supernova, the outer layers become a nebula, which is basically a gas cloud, from which new stars might form over a long period of time.
The core has turned into either of two objects: a neutron star or a black hole, depending on the initial mass of the star.
Your first comment is right, when two neutron stars collide, a kilonova happens, but remember that this is an event, not an object.
Now I haven't done much research about this, so I'm not entirely sure, but I believe a kilonova can result into either a neutron star or a black hole.
So to answer @David Augusto Jr's question, Im actually not sure there _is_ any black hole, it might just be another neutron star.
Keep in mind that this is just an artist's rendition of a kilonova, it's not supposed to show an actual neutron star merger, so they might not have focused that much on whether the result was a neutron star or a BH.
This is all, of course, very simplified, but it's pretty much as far as my knowledge goes, I am no physicist. Still, feel free to ask me questions if you want to, I'll try to answer the best I can.
If you want to go further, you can start with Wikipedia: en.wikipedia.org/wiki/Supernova
WTF IS KILONOVA? WHY'S NOT MILENOVA?
Power of inverted spear of heaven:
and thats how you create uranium
Gold can create in this process
Yep, star dies once Someone: "choose how you will come back to life" options: Blackhole, and neutron star star: hmm i choose neutron star. Someone: excellant choice sir. *star makes a huge explosion and turns into a neutron star* **1 million years later another neutron star appears** Star: no, No, NOOOOOOOOOOOOOOO *kilonova and both of them just.... disappear leaving their dead remains*
the neutrons spinning looks identical to the Norway Spiral.
i know its not but the animation on the news today made me think of that weird spiral from a few years ago.
btw, im really effing bothered by the fact that no concrete explanation has been given by any authority in regards to the Norway Spiral. it was not a rocket trail ffs. you dont have to be a physicist to know it certainly looked odd.
any insight from a professional would be great🖖
Why are you "really effin bothered" by this? If you're so effin bothered why haven't you researched it? It's only a mystery on conspiracy sites that are in the business of click baiting credulous fools. As Tony Wells says, it was indeed a failed Russian missile launch, but you want a "concrete explanation" from an "authority"! Well the Russians agreed that a missile launch occurred at that time - we now know the missile's third stage nozzle failed causing the missile to spin like a Catherine wheel. Prior to the Russian statement an astrophysicist at the HSCA had suggested that was the cause. Incidentally there are videos of missiles failing in exactly this manner.

Imagine having to die twice and bring another one to make you a black hole
This post was made by supermassive dying stars gang
Wouldn't that become a black hole?
no.. black hole happen when planet die.. but this Star freaking dancing yooo 😂. IJK
Nope, instead it's like crashing 2 nuclear bombs together, it creates a double-power explosion
Depends if the star died from huge mass or old age
Yes but technically the debris around the black hole would Illuminate. This animation takes away a lot of the debris and gasses that would be held back by the black hole. The perspective has to be a few hundred light-years away as well.
I have to admit its just a representation and not an exact portrayal of an actual collision.
It would rather form a black hole or make a bigger neutron star
Beautiful animation but inaccurate.
The merger would have created a black hole. Not a smaller neutron star.
