- Scientists have discovered the cause of the brightest burst of light ever recorded - but discovered two even bigger mysteries in the process.
The burst of light, spotted in 2022, is now known to have had an exploding star at its heart, researchers say.
But that explosion, by itself, would not have been enough to have shone so brightly, and the discovery casts doubt on where heavy elements - like gold - come from.

An even bigger mystery is how do we get rid of bots trying to sell crypto coins in CZcams comment sections....
Not possible. Anyway would you like to invest in shitcoin or scamcoin or maybe bitcon
Oh, is that scam still available?
You get CZcams to spend some effort to stop them as illegal advertisers, since they didn't pay CZcams any $$$ then CZcams recruits them to sell their stuff thru paid thru ads via Hong Kong Advertising companies just like all the OTHER scammers.

Ah that classic Oasis hit, ‘Smashing Supernovae’. Takes me back…
😂
Champane Supernova... In the sky?
Somebody tell the poor lady 😂
loool
And hulks gamma rays
Just glad it's that far away! The energy released mind boggling deadly.
I can handle it
Far away and a long time ago
And even at that distance, it did affect our ozone. Astonishing power
This Super Nova was 2 billion light years away? So.....the light from it took that length of time to reach us, and we saw it for what? 7 minutes? This explosion was old before the first Human walked the Planet!!
That is relativity, right?
The explosion was old before we had multicellular life on this planet...
Allegedly!
Yep. Leave it to women to always bring up old shit.
@@moonshoes11not relativity, it’s about the speed the light. It took that long for the explosion to be visible on earth, because the light of the explosion just reached us here travelling for this much time. Cos yk, it’s massive massive distance
for anyone wondering supernovae is the plural of supernova
Thanks for stating the obvious.
This "professor" got it wrong though lol
Thanks, I thought that was a whole new phenomenon.
Thank you because I was def wondering what she was talking about!
Maybe the nova identifies as "they" 🙂
*Maybe don't underestimate us small stars* 💪
As a big one, I can confirm. One of my army buddies was small enough to punch me in the back of my knees. Impossible to stand against him in a fight.
@@johnd2058 3 inches isn't big
@@wednesdeity It is above average!!!!
@@user-ld2iy4fo6g it’s large I’d say
Stars aren't small they just come in other sizes.
1:16 *Supernova (supernovae is the plural)
1:19 _"Champagne Supernova"_ is the Oasis song
#FacePalm #SMH
I actually cringed when she said it
Saaaaaame
I came here to say the same thing.
What do you mean? _Smashing Supernovae_ is a great song.
Thank God I'm not an Oasis fan, that sounded like it would've hurt. 😂
My sincere thanks for sharing it.
The chemistry between the two was lovely. Mutual excitement channelled into informing the masses. :)
Ur gay
This looks like an exceptionally powerful axial beam. I personally never expected to ever see something like this. Pulsars have a somewhat similar force. I love that she actually talked about how massive compression forces during supernovae likely form low mass black holes during the event. I still cannot imagine the requirements for a supernovae to produce such exceptionally powerful axial beams at this solar mass and energy. Much study is required! So exciting!!
I've always wondered how axial beams come to be. Is it a product partially anyway, of the fact the object is spinning so fast?
That supernova is small fry compared to Professor Catherine Heymans teeth generating the brightest burst of light in recorded history.
This is the second time I've seen Heymans on BBC - I love her explanations of things, even if I'm already familiar with a lot of it!
She didn't answer any of the questions specifically...waste of time asking her
Really? She repeated what we already knew, made loads of mistakes and answered nothing. She’s terrible 😂
And yet you didn't notice she mispronounced supernova multiple times?
@@CaptainBollocks...., she said "supernovae", which is the plural of "supernova" 😐
@@phunanon Yes, but she also used it when talking about the singular, AND when talking about the Oasis song
It is probably an Imperial Death Star test firing exercise.
what a lovely smile it has brightened up my day
yep, the person with such a smile can bite off your hand and do not notice 😄
Aliens can you see our signal 😮
The smile signal
@@kabirsingh2193 The smile of Violeta Friedman
They can see what kind of toothpaste you use! They're watching YOU YOU YOU specifically!!
🤣
YOU ARE BUGS
Can you see the signal Dinosaurs probably 😂 they were about when it left the origin
She’s driving me crazy using the word supernovae! 😂😂😂
Could it be that this super nova was aimed directly at Earth instead of an oblique angle of gamma rays? Could the aforementioned be the cause of the BOAT?
Possssibly but it’s really hard to tell. If it was a gamma ray burst then absolutely that would be the easiest explanation but since it’s a supernova, which tends to have a more uniform energy dispersal it’s kinda hard to tell.
My imagination says we might be seeing new insight into how pulsars are born with their radiation jets at the poles.
However that would leave us wondering why it’s not got a variable magnitude.
It would help explain it but that’s literally just entirely guesswork.
Those damn aliens need to keep it down. People are trying to sleep here.
And the other day I was reading about a star that is shooting a beam 40 trillion miles long. That is enough to go to our nearest star then halfway back again.
Mindboggling stuff the universe is.
Maybe small black hole passing through the star, aggitating it beyond repair🤔
alignment of the supernova has a great deal to do with how bright the gamma rays are, given enough supernovae in the universe, one is always closest to a bullseye...
I wonder if the guy who invented science thought his work would lead to this, amazing underdog story
Reporter learnt absolutely sod all from that encounter 😂
Perhaps stars detonate for different reasons? perhaps dense star pairs which are near core collision have massive cores that detonate simultaneously or even asymmetrically? and therefore create a long spent and broadly spewed radiative event that is more like a multiple detonation event? The shockwaves of asymmetrically detonating stars of maybe twice the mass of our sun ( there could have been three or four or more) could have created a long and bright novae event that cascaded and didn’t create too many heavy elements. The elements created would have been from reverberating superheated shockwave events. You might get potassium. Or you get cobalt or even rarely iron, which was likely the remnant of another long ago event. Actually probably get more silicon and other elements low on the periodic table. It’s seems to me that several stars in a dance could go super critical, and therefore not fusing much more than iron.who knows in a supercritical storm of superheated non matter in such an event. What might one get?
she doesn't need to be married to have a gold ring. 😂😂😂😂
... and to have known about gold you don't need to have acquired a gold ring either - some reasoning by a scientist! must have had a recent wedding where she saw her first gold ever
her wedding ring just exploded, probably
She seems super nervous but trying to contain it.
Seven minutes is a long time compared to other cosmological 'flash' events. Did they actually catch the whole timeline and scale so as to form a graphical representation?
Who you asking? You know the TV can’t hear you, right? The lady in the video isn’t going to respond to your question.
@@jimmygrizz9341 You know other people will watch this video, right? You know other people will read the comments, right? You know other people might know more about the full report, right? You know other people aren't toxic and irrelevant like you, right?
i'd imagine there are at least a few graphs of the event. haven't seen em myself, but data would be standard. should be available when study is peer reviewed.
@@jimmygrizz9341 Well, actually... this _is_ the BBC channel, so you never know.
That was one of the weirdest 3:44 mins of my life 😂😂😂😂😂😂😂
Anyone know why she keeps using the plural supernovae to refer to a single supernova?
She's not, it's a regional accent.
@@JeffreyGoddin what is the region her accent is from? Are there other words ending in a but sound like ee in that accent?
@@danielhenderson7050she’s not Scottish
@@JeffreyGoddin Certainly not a regional pronunciation
@@danielhenderson7050 Sounds like a standard Home Counties accent, they say supernova like everyone else
I love the acronym!
Didn't know that the mouth of Sauron was an astronomer aswell...cool!
I want to see more science news
A typical supernova doesn't produce anything heavier than iron. Elements heavier than iron (like gold, platinum, uranium) get created in neutron star mergers, which themselves are remnants of a star going supernova.
This was a single star event, and yet the professor wrongly kept referring to it in plural (supernovae, with an "ee" at the end).
😂 big red bunions komrade
Infact, she didn't answer anything ...just explained in a roundabout way what most of us know anyway...where do they get these people from
The main problem is there aren't enough kilonovae to produce the amount of heavy elements we see out there. It has to come from somewhere else too
I speak Latin. For some reasons, there are many more speakers of Latin than what anyone is lead to believe.
It is difficult to give an idea of how many mistakes people make, when they speak even a single word of Latin, pretending to know what they are talking about...
The Chicxulub asteroid was one giant lump of iridium. It left a visible layer of the metal in rock formations all over our Planet...
The boat 😂
What is a supanavy?
Doesn't this example place doubts on the concepts of standard candles which are used to identify the expansion and expansion rate of the universe.
Wow, Sounds both Marvelous and Mind Blowing
The B.O.A.T.
Luv it ❤
What is a Novy? I’ve heard of supernova, but not supernovae.
So this explosion happened over 4 billion years ago and we're just now getting that light.
The exact position?
Mystery is a necessary part of our identification as living people. It arises out of the continuous distinctions that we make, which form our experience. This is due to the fact that we usually make those distinctions before we make the reasons that we use to explain them.
In other words she didn't answer anything specifically
Not visible light but a gamma ray burst. Different from a super luminous supernova 2015LH.
As a scottish guy living in the US I am well aware that we handle collective nouns differently. For example here in the states you could never say "our team are" as a collective it is always singular. I have NO CLUE why this contributor is saying the singular indefinite article followed by the plural. It makes negative sense. It is like a mistake was made and added to ha ha. Oh well. On to my next irritation I suppose :-D
I thought they were talking about her BOAT teeth.
Seriously though, a possible explanation would be that the emission was not radial but constrained by a magnetic and/or gravitational field into a jet (well, two diametrically opposed) and the Earth was lucky enough to be in the right direction. Was there ever such a jet supernova?
Could be multiple of things given it so far away? Obviously this must mean that space black mater has a lest density which will obviously have this affect what else would this mean probably the end of a black whole what goes in must come out
I thought they already figured out that supernovas don't make gold and platinum. It is neutron star mergers that do this. That was a few years ago that they figured this out.
The main problem is there aren't enough kilonovae to produce the amount of heavy elements we see out there. It has to come from somewhere else too
@@kennybevan11 I didn't know that. I will look it up. I think a good chunk of the heavy elements some from kilonovae. I know they saw , ordinary supernova don't make much at all.
So, as I understand it: the Hulk drank champagne at a super Navy wedding on a big boat wearing a gold ring made of heavy chemicals; and in a disturbing development, the Joker now controls the body of a professor of astrophysics; but if that's the case, where's Batman?
That dangerous looking gas pipe in my garage. Wicked.
How many hulks can it create?
This is why I am always saying we need to be careful and watch out for big bursts of light from billions of light years away. Thats why you should always cover up when outside. All that Ultra violet rays are very bad for you. Similar to a sun bed
advanced aliens testing a weapon. for peace, of course.
Is a super novee different from a Super Nova?
A Supernova is singular and Supernovae is plural. Nova is Latin for New, hope that helps.
Supernovi? It's supernovA, singular, not plural.
You would really need some facts did U see the star there before the bang? We're in the galaxy did this take place .?I would say one last theory ?more likely had high quality of magnesium in core thefore brighter light
interesting................
The insignificant star produced the brightest light. That’s some notes for life.
Dynamite comes in small packages 👌
Gold is made by neutron capture not in supernovae according to Arvin Ash.
I don’t know about any bright supernova, but I do know some bright teeth that are very distracting.
Brighter still is Prof. Catherine's smile ❤
The Universe Is Mysterious Indeed...Unexpected, Yet There It Is...A Gift For All Of Mankind To Behold.
Whoah!! Her smile, it was her smile overpowering the data..... I'm blind...
the BOAT lol
“And a smashing Supernovie in the skyyyyy”
Only supernova I got was from those teeth woah 😬😮
Well... Heavy elements may just lean towards being dark matter after all. Who knows a dark heavy gas like plasma
What is supernove ??
I think 'Supernovee' is the plural, or the Scottish maybe.
the star was small, ive heard the universe was pretty small once
Sainsbury’s probably have better data on the subject
🤣🤣🤣
The scientist also played the Mouth of Sauron in The Lord of the Rings Return of the King Extended Edition
Her dad was the frontman for Electric Mayhem
That's was just me in my spirit on my way to c my other self in another dimension....
She has got to be the most condescending person I've ever had explain something to me.
Why? She said nothing that cud be taken as condescending, she knows very little of stellar mechanics and wanted to understand from a Professor.
Yes considering she didn't answer anything 😢
@@SimonMcGrath-oj8kg I'm pretty sure people know what gold is without needing to be married and own a wedding ring, just for one.
@@rather_be_a_cat To be fair she was using that as an example to people who don't no where the heavy elements come from, young kid's say. Now we no it's not the stars per say that make the heaviest elements but their 'off spring' shall we say Neutron Stars. I get ur point tho and u r right
Twinkle Twinkle little star
How i wonder wat u are
I've found something brighter than that star, her smile. ✌️
Before being too sure of our importance, think of this...
You're just hanging out on the porch having an evening refreshment. Something goes wrong on the other side of the galaxy. Five minutes later you get the sensation that something is odd about the sky. Before you can look up, everything for millions of miles in any direction is turned to molecules..
Have a nice day. 😁
You got the Astronomer Royal of Scotland to tell us what a supernova is? Why do astronomers think they can't talk about anything but the most basic topics in their field? How many times have we heard the definition of a black hole - Gravity so powerful, not even Light can escape. They just repeat the first-year stuff over and over.
I think I solved the mystery. This professors grin might've been the catalyst to the supernova
What a "bright" set of choppers on that Astronomer!😁
Great news !
People who love what they do! It's contagious 😂😅
Listened to find out why this light was so bright from such a small supernova (question posed by the presenter who incidentally has an unnerving way of staring at the camera) and after the astrophysicist then repeated exactly what the presenter had already said and after lots of other sidestepping I learned precisely nothing. In other words they don't know diddly squat.
Those teeth smashing together can probably be seen from their end too.
Oh that was probably me accidently turning on discord light mode... oops
When the star farted. it was pointing at us. Simple
Does it mean that it burst 2.3billiion yrs ago?
maybe it was so bright because its directing its light towards us
We were all our Grandma's brightest-ever bursts of light 😘
B.O.A.T! I'm loving it!
What's a "soopanovy"?
In a gLaxiy, Far, Far, Away, a Deathstar Strikes. May the 4th be with you.!
If I do a bigger explosion when I take MDMA again, will you finally believe me 😂
not chemical , it’s heavy elements
Nova or Novy. Potato or Poteito. Maybe it was a super novy poteito explosion. Science will never know.
So what was the cause of the brightest-ever burst of light? You can't just say 'regular old supernovae', as that's not really a definitive cause is it, otherwise they all would.
I cringed every time she said "supernova"
Bear in mind that this event happened 2.4 billion years ago and it took light that long to reach us .
I've seen her in LOTR.
It's gonna roast us like a marshmallow
She says it happens once every 10,000 years or so. There is a gazillion stars. Shouldn't it be happening all the time? How did they get that number?
how old are you? 10k? 20k?
@@Kessoku Sorry I don't understand what you mean.
Basically what I am kinda saying is just because we don't see it doesn't mean its not happening?
