I've never seen a kilonova blow up, but if it's anything like my old Chevy Nova, it'll light up the night sky!
You legend. Shut up and take my like.
What he said☝
What he said☝
I used to have the Buick version, love that body style.
We had an 88 Nova when I was a kid. It got over 300,000 miles on it before it died and had incredible gas mileage. We all loved that car.
I read, and correct me if I am wrong, that when Hubble is finished they will burn it up in the atmosphere. I wish they could somehow retrieve it and make a special place for it at the Smithsonian. I realize the size is massive, but it has done too much for us in Space exploration just to be burnt up into nothing and should be displayed imo.
Agreed. Such a terrible waste of expensive materials and gear.
They could bring back just the lens they had problems with at launch, kinda shows our resolve.
Its just a repurposed KH-11 spy satellite, there are others including not launched ones that are already used for display in the US. Not to mention, they may be issues of radiation and radioactivity associated with returning it to Earth, even IF you consider it worth risking the lives of humans to ride a rocket into space and attempt reentry with it.
Always rocking it sir. Thanks for the hard work helping us not so bright folks learn every day
I never worry that I'm not going to understand what's being discussed when I watch Anton. He's super smart but never seems to be egotistical. He's awesome. This is my absolute favorite science channel.
Speak for yourself lad 😂
Anton, your uploads are such a refreshing escape from our chaotic month. Thanks 🙏👍
Hubble still seems to be very important
Well, yeah... No one says it isn't.
Let's not forget that the amount of data that gas come from Hubble can still take many years to go through. Combine that with wanting to keep using it for as long as possible, and that's what you get.
It certainly has outdone itself, despite problems early on. A very valuable telescope until the James Webb telescope can get up there (it's been delayed for a few years now).
Even with the James Web in operation, Hubble will still have work. The JW will be working towards its limits much of the time.
Cool, funky, interesting? Sure. Am I happy to see it funded? Sure. Am I happy to see JW telescope funded? Sure. Important? That's a heck of a lot harder to argue. How, precisely, will it affect humanity over the next century that we did this experiment?
We just witnessing a 6 billion yr old event.
that is just one way to think about it. It would be equally correct to think of anything perceived now (light arriving to us now) as happening NOW. Because the speed of light is the speed of causation and for all intents, equivalent to instant to us. If we ever figure out hyperlight travel, we would have effectively learned how to travel backwards in time.
@@dfpguitar Which is why we dont think of things we percieve happening at the moment of perception. It is most definitely not correct to think of things happening at the point of perception as it breaks how we perceive time.
@@spwicks1980 The problem there is that our perception of time is wrong and needs to be broken in order to confirm with relativity. Non-classical physics are often like that: You have to forget how you perceive time, location, probability, mass, energy, etc. etc.
@@andreasferenczi7613 That could well be true. I've just got so used to the consideration of such huge scales of time and space it seems alien to condense that scale right down. I still however come back to how we would perform measurements without our current understanding of the arrow of time. Then again the future may bring about some new understanding.
and hearing about the limits of seeing the gravitational lensing wow so neat!!!!
ty wonderful person what da universe!!!! cool!!!!
Whenever I'm stressed, which is every single day, I come to Anton. He tells me I'm a wonderful person, and it makes me feel warm and loved during these troubling times. You'll never know how many people hold on through your videos Anton!
Imagine what emissions they are seeing now from the Milky Way 6 billion years ago.

We're just seeing it, but the actual event (the two second, bright flash) occured before Earth even existed. Wrap your head around that, if you can!
Why are people so fascinated with that? We can observe the big bang still and that happened... ...in a way right now, but that's relativity of time, there is not really anything like before, now and after, everything is and depending on your point of view different things happen at different times. This event happened now for us. Us observing the event will/has/is happen(-ing) 12 Billion years later than the event happened for them.
It's really difficult to explain things that go against our most basic intuition like this.

Anton, my goal for the next few months is to Like every single one of your videos. They are interesting, very well done and it honors me to support a fellow Canadian from the province of Quebec. Thanks for everything you're doing, can't say this enough.
You just brightened up my sad day.
The event that ends humanity will also “Really surprise scientists” Ive always hated that line when it comes to bright flashes in space.
Humanity is an animal species. Extinctions happen all the time, without bright flashes. Cause no. 1 is evolution itself; to evolve so far it couldn't produce viable offspring with its million-year-old ancestor anymore. Add to that changing environments. Which is what we are currently doing.
You are the best! Have a great day anton!
What if two magnetars collided? I know they are incredibly rare, but the universe is big and our instrumentation weak. I suggest these events happen much more often than we have been able to detect.
Dam good question !! Any cosmologists in the room ?
Magnetars are probably just fast rotating neutron stars with their magnetic poles aligned with our line of site from Earth. Sort of like blazars/quasars/AGN... the difference is mostly just our vantage point. And yes, neutron stars collide all the time,
The main issue is that rather than being "rare" in quantities magnetars are extremely short lived with a typical lifetime as a magnetar of no more than around 10,000 years.
Yes that is only tens of thousands of years these are objects that exist in a cosmic blink of an eye. For comparison definitively modern humans have been around for 80,000 years so our species time frame long outlasts a magnetar by at least a factor of 8 times.
In fact accounting for their lifetimes the fact that we see around 30 of them in the Milky Way alone implies that there must be many billions of former magnetars that have formed over the lifetime of the Milky way as newly formed magnetars replace the burning out magnetars. A
Also they are surprisingly common within dense environments like globular clusters and the galactic center which is one of the reasons they are thought to be produced by stellar collisions the other being that stars known to have formed by mergers such as blue stragglers have extreme magnetic fields.
They actually seem like a fairly good Fermi paradox filter candidate since on December 27th 2004 a Magnetar around 50,000 light years away had a comparable effect on Earth's magnetosphere compared to a Coronal Mass Ejection from the Sun overloading Swift despite the telescope being pointed in the opposite direction and even sending spacecraft into safe mode but I digress.
Neutron star mergers appear to typically take a few billion years to slowly approach each other via gravitational waves with kilonova type events statistically appearing around a billion years after star formation activity some of the strongest evidence probably comes from galactic archeology in the local universe tracing r process elements and when they formed relative to star formation or by directly observing kilonova host galaxies.
The point is that by the time two neutron stars collide even if they formed as magnetars they will have burned out their magnetic energy over a billion years ago. Thus it seems extremely unlikely for two magnetars to collide as you need the collision to happen within thousands of years of formation.
likely just form a black hole...
@@Dragrath1 insightful stuff, thanks. But are we really that certain of the lifetime of magnetars or the true distinctions between them & neutron stars? And can we discount all mechanisms for reforming them? What makes pulsars so stable compared to magnetars?
Thanks again, wonderful Anton!
These images are BREATHE TAKING Thank You for sharing
Your videos are always very informative, Anton. Thank you
This is a news channel that never fails to inspire me, and it doesn't feature any politicians. Thank you for these videos, Anton!
Politicians seem incapable of telling the truth. These events are incapable of telling lies.
Phenomenal video's and explanation's. Thanks!
Thanks Anton been waiting for your video on this one 👍🙏❤️
Thank you Anton for the time and effort you put in your shows, you are well appreciated. Thanks for your help and time yours sincerely Gary. London
"hello wonderful person this is Anton" I needed that today man. Always appreciate the videos.
Another wonderful thing shared by a wonderful person. Thank you Anton.
OMG OMG OMG, I'm about to join Professor Arcones' Team!!! She co-coined the term kilonova! I already did an apprenticeship there and worked with their simulation on kilonovae. She has a very interesting talk about her work on youtube. But its pretty out of date because LIGO has since gone online and now we actually have real data to compare our simulations to.
6:32 that was exactly what I was working on: testing whether using less data from the supercomputer would still pop out the expectet elements.
Strange object! Thanks Anton!
Thank you wonderful Anton.
Cool info! Anton you are da man...we love you dude.
Thanks for the info Anton!
(When was this first observed?)
This kind of answers an Idea, question I had a few days ago. Thank you Anton.

Hey anton I've been watching your videos for a long time now.. First time I've commented. One you're AWSOME. And keep on making videos! Your very passionate about what you do ! Do you work in the scientific field? What do you do for work, are you in The u.s? You should be working for nasa or JPL! Thank you for the years of cool and interesting videos! And also the free education! You are awesome anton!
Watch it ends up being a lot closer than they originally thought.
love this channel :D

The most extremely extremely unusual extreme video to date!
"...almost certainly convinced that this is most likely..." To an old man, this 21st century lingo seems to lack hard edges 🤔
it's basically a tiny blip of no more than a few pixels. this is almost entirely conjecture.
@Anirban Chakrabarti I have looked into it a whole bunch. I used to think I understood it all rather well. The more I look into it the less sense I am able to make out of any of it.
Scientists somewhat believe that the chances are it was most likely an event that is completely unexplained, probably. This is only conjecture, though.
Its researchers lingo
Everything is relative these days, otherwise someone's feelings might get hurt...
About 15 years ago (around the time of the Katrina hurricane), I was backpacking in the high Sierra mountains (California), after star gazing in the completely moonless night both my friend and I saw a similar event. Out of nowhere a very bright light quickly grew in the sky and then after about three seconds completely disappeared. It wasn’t a diffuse light but an extremely bright orb, and of course no sound or residue in the sky. I thought it may have been a super nova, but your description of this event sounds more similar.
Anton, you should, be narrating, how the universe works. Have your own television series, and I, believe you should be invited, to do a guest appearance on the cosmos. Keep Rock-in!!!! You're very intelligent, and i, enjoy listening, because what you air, you make it more interesting, and you know how to get, the subject in layman's terms. To be easier to understand. Hope to see you on TV Soon. Break a leg. Good Job, you deserve a chance.
Wow!!! Anyway you could help us understand the location of this event? Perhaps it happened in a constellation we are familiar with? Did it happen near the constellation Aquarius by chance?
Hi Anton - thanks for another fascinating video. I was wondering about the necessity for gravitational wave observations to come from (relatively) nearby events; what happens to GWs coming from great distances? are they absorbed or weakened somehow over distance? I can imagine a propagating wave getting somehow stretched as the spherical wavefront expands, but if GWs are distortion of space-time surely they can't be stopped or absorbed by anything?
Hello wonderful Anton.
Awesome. Saw the 1987-88 Supernova. Spent a good half hour wondering what the hell it was? Then as I went back inside I realized it had to be a supernova. The next night they were talking about it on the news.
6 Billion jears ago, everybody in that Galaxy: "Look a second sun!"
More likely " What the f-AAAAAARRGH!!!..."
And then they were instantly vaporized.
FLASH
AAAAAAHHHHH
Anton's such an underrated YT all jokes aside
Saviour of the universe!
Why did i read this as "Creation of a Magmar or some other strange pokemon just seen".
There's an element of masochism in my love of neutron stars.
this the new time Anton? its great for me in the UK
Same here in Australia too!
aye, 9 or 10pm
But if this object is 6 billion light years away, then we are observing an event that occurred 6 billion years ago...before the formation of our own solar system. Hard to wrap one’s head around this. Freakin awesome!
This would be great if it's an actual Magnetar. They are very interesting and to see one created is even better.
Excellent as always. Two probably silly ideas as to what it was: Any chance this was the collision between a neutron star and an antineutron star? Any chance it was the formation of a "quark star"? Just wondering.
@The Journey Different combination of quarks.
Best CZcams channel
I just don't understand how such a massive collision result in a flash that only lasts a couple seconds.
It is probably because 2 seconds is an incredibly long time. If we think about the minimum time even the fastest physicals reactions need, we can probably use the Planck time, and that is 5.39 × e−44 seconds. That tells us that a whole lot can happen in just a second or two. In comparison imagine how utterly and ridiculously OP modern CPU's are, and they take instruction around 1xe-10. Although not entirely correct, I still think it's a meaningful way of thinking about it :)
I wish a wonderful person such as yourself a really jolly day!
@ Anton,
Near the end of this video the audio started to distort. I also noticed this from the last vide. Other then that, another great video from you. Peace out ✌️
In that all the graphics depict the flash as magnetically guided beams from the poles, we were lucky that (1) it was aiming at us so we could see it and (2) that we weren't close enough to be vaporized.
Hello wonderful phenomenon !!
Two neutron stars colliding is so powerful can be seen millions of light-years across space,even folding space time as easy as folding a shirt.
I remember seeing a light shooting through space when I was camping as a teenager many years ago.
Could I have witnessed such a event I wonder?
My shirt has boobs in it, we would end up slung too far.
@@facethesky1066
Most of my shirts are the same!
My partner still ignores my pleas and wears them!
I'm starting to think he's just locked in a basement being held captive until he releases 10000 videos
If we can see these events from anywhere in the universe, expansion of space must have stopped.
Thanks Anton...
Since the Earth has rare elements, and the sun is at least a second generation star, there must have been some really violent shit going on in our neck of the woods long ago.
I recently learned that two neutron stars colliding could release 200 Earth masses of gold and 500 Earth masses of platinum that's freaking awesome.
Well, we are all made from stardust.
3rd generation. and long ago our neck of the woods was waaaayyy over there.
@@TheShootist You're right. I imagine that 5 billion years ago, the Milky Way was arranged quite differently.
Supergiant stars have a short lifespans of around 10 to 50 million years, so some matter can have been recycled several times.
Anton still loves using those extra adverbs that end in -ly lol...clever way to ACTUALLY make videos longer 😎
We are just beginning to understand what we are seeing around our universe. We tend to think we know more than we do. That's why all of these observations are so unexpected by mainstream science.
Hello Wonderful Anton :o)
Hello Wonderful Anton. TFS, G :)
Anton's the best
Anton idk if you read your comments but mister I seen 1 hell of an explosion way out in space and man it really was a big deal. Just before it happened that part of space was totally dark, no stars. When it happened there were a number of objects between us and it. Some just on the other side of it. Was a total halo eruption. Lasted a good 10 seconds or more before totally fading away. It was the night a Japanese man like myself, noticed Nova Delphinus glow up. At first I came forward and said I had seen it too. They told me I seen nothing. What I know now that I did not know then was, at that time Nova Delphinus was directly above me. This explosion was on my extreme eastern sky at 11:45 that eve. I had originally believed the only star on that side of the sky that night was Deneb. The star I seen might have been Arcturus. Not sure. It was not a perfect halo. It actually looked like if it was a shot in this direction, which it was actually, it would have skimmed across us. Orbs appeared out of the dark totally lit up and were many. And they looked perfectly rounded like tiny balls. You could see the way the exploding light wrapped around them and made them stand out. In reality in the complete blink of an eye I was looking all the way through space as if I were in a tunnel. Everything between us and it instantly stood out and I could look through space like it was 3D. I could see distance. I feel blessed to have seen such a thing.
“Currently producing a lot of stars”. . . “currently” being 6 billion years ago. . .
6 billion years is a blink in terms of galaxy lifetimes. It will still be generating new stars now, I'd wager.
Photons don't have mass. So it doesn't experience time through space... Lol, so why does it matter again?
i was about to comment this haha xD
@@hazode it could be generating new stars it could also be gone already :D we will know in 6 billion years so keep tight xD
Makes me wonder what those living in that galaxy would have seen. Would this event have destroyed the atmospheres of Earth-like worlds thousands of light years away? How many civilizations went extinct in this event?
After watching his vid on Hypernova’s... supernova’s so powerful they can dissipate their own blackholes to leave nothing and... possibly exterminate life in 1/3rd of the galaxy... any bright flash like this would serious freak me out.
Neutron stars are without a doubt my favourite thing in the universe
So that happened 6 billion years ago ... and it only reached us now
Thats how the universe works...
You couldn't make this stuff up. Wild!
The Star Maker got a new, bright idea )
Holy Batman ... imagine how cool a "no cover up" would be! Thanks for telling me what I'm looking at, finally!

Or...A magnetar/starquake/ pair of neutron stars colliding. The magnetar seems to be a short lived (relatively speaking) type of very rare neutron type. Take your pick!
Very scary to think this all happens just out in our universe Anton... how do we know we are not destined for something similar in our own solar system?
That is the craziest thing I've ever seen. (Since high school.) 6 bil years ago & a solid percentage of the known universe away, more energy was transformed in 2 sec than our star will convert in 8 bil yrs !! and we just watched it happen. Colossal. Unthinkably so. Thank you for bringing it to our attention wonderful skywatcher !
The diameter of an orbit never decreases. This is because the two objects in question, like our planet and Moon, always begin their lives as a single, spinning mass.
What is being seen is an unfortunate, very energetic mass that was shot by a planet type mass at an extreme speed. This massive brightness will wane over the next few months because the once single mass turned into a trillion pieces that will cool much faster.
Hello wonderful Anton! this is person.
Sweet!
Only 30 found, but those are magnetars pointed directly at us, right? So there should be plenty more that AREN'T pointed towards us. Could we even tell if this new event produces a magnetar if it's orientation isn't perfect?
Wonder if something runs along the tendrils that connect things in space if it will affect it as far as our perception of it goes.
Gravitational waves move at the speed of light?
I'm just glad it didn't happen in OUR galaxy.
Neutron stars are only super dense when their matter stays put. If any gets knocked out it will suddenly expand as it attempts to become normal matter again. That rips it apart releasing the rest energy.
That smells like gold to me.
Magnetar would be a great metal band
Hey anton i enjoy watching your show alot. I have seen something in the sky above me that I've been trying to find an answer for. Im in toronto more specific hamilton ontario...i looked up b4 going in one night and almost directly overhead i had witnessed a super bright flash that quickly (in a round shape) exploded outwards retracted alittle and then blew out more to 4 times its size then collapsed in on itself all happened within 5 seconds. With the nakid eye. Ive been watching faithfully to find an explanation.
I thought super nova of some kind but ive never heard of it retracting unless maybe a blackhole quickly took all back in? But we havent had a supernova for what i recall 300 years or so? Is there anything recorded in records for this event? It was late spring early summer . Thx
just wondering,could micro blackholes appear,then disapate at a low level state?leaving a reminant to produce a larger energy state?
Maybe objects far away over 6 billion lightyears are being magnified by gravitation. If spacetime had more energy in the past then it would bend spacetime more and Dark Energy would be normal gravity. ( imagine the gravitational effect of the mantel of Earth if we were at the centre of Earth where we would be weighless) Red shift may be an indication of accelerated space-time. I think space-time is curved as we look back in time. I dispute the CMBr results of flatness as I think the radiation comes directly from the vaccum of space itself.. micro bangs rather than one big bang event. I'm convinced the universe is eternally dynamic and folded back on itself with no beginning or end.
I fear I may live the same life again over and over and over....
Magnetars frighten me. Black holes keep themselves to themselves but magnetars want attention from everybody 💥✨😊😄😉
