no thanks im full
Thank you Alex and the Astrum team for making this video.
SS 433 blows my mind. I’m going to support everyone’s efforts, thank you.❤
Not interested!
@@sssnake1654What? The moon does rotate. It rotates at the same speed as it orbits the planet which is why we only see the one face. It takes 27 days to rotate on its axis and 27 days to orbit the earth
@@ashleyking6743 Huh! I stand corrected. Thank you Ashley.
“Dad, I want a quasar, all the other galaxies have one.”
“We have quasars at home son.”
The quasars at home:
lolllllllllllllllllllll sgr a* thrifty af aKA cheap
dont aggro the universe dude.
Hilarious! Best analogy! 😄😎
Ah, i love ordering a quasar from mcdonalds
Funny stuff 😂😊We are blessed to not have an ”eraser” nearby. 🤭
We had a Quasar in our living room when I was a kid.
Billions die as a relativistic stream of matter obliterates their planet.
"It's a girl!" 🎉
I remember " works in a drawer".
@hherpdderp your comment needs more attention. Gender reveals are this stupid it wouldn't surprise me if an offshoot of the human race in the year 5000 destroyed their planet with a pink or blue mini quasar.
Lmao 💀
@@SpicyMang0s Now I understand why Mom always told us not to sit so close! 😳
I want a T-shirt with the Andromeda Galaxy on it with a caption that reads "IT'S COMING RIGHT FOR US!!"
Could that also be a very small form of matter mixing into the gamma rays?
Me too
Have we ever captured pictures of two stars colliding?
Oh, nothing to worry about really! As does any main sequence star, the Sun heats up over time. Multicellular life on Earth has ≈500 million years to go, and single-cellular no more than 10⁹ years, when oceans will boil off. Andromeda won't get even much closer in that time, so we'll certainly escape it!
@@travisjohnson622 Astronomers have observed contact binaries - stars with connected gas envelopes.
Title: do we need to worry about quasars?
Space: if you can see it, you’re already dead.
So we die every time we see a star?
@@TehAntiSpammerwe’re talking about quasars not stars
@@brandon2755 Even thats wrong but alright. seeing them doesnt mean you're dead. If they are pointing directly at you AND they are close enough.
Make one yourself. The sky's the limit nowaday. If necessary, bio- or 3D print one. It took me 5 years but my replicator's finally finished.
Look at it and confirm.
There was a TV manufacturer back in the early 60's called Quasar. Their slogan was "Works in a drawer". You could literally open a little drawer with the circuit boards inside! It was the first high tech TV set. Every time I hear the word Quasar now, I hear that commercial in my head. Probably an off shoot of the space program. Pardon the pun. Cheers
Omg! I remember these televisions being around in the eighties! I completely forgot about them until now! I think my small television in the garage was a Quasar brand…thanks for the walk down memory lane though!
@@ValkyrieofNOLA ❤
I am an amateur astrophotographer and I always find many quasars in my photographs, some that go up to 9 billion light years in distance. Yes, I have some of those in my space photos shot in my backyard with my large telescope. It's dope, they are just dots, nothing fancy but their light is there and it's amazing.
That would be amazing
So you found tiny black holes around these quasars too?
@@matthewboire6843 what "would be" amazing? The op didn't speculate about anything theoretical.
@@djvapid being able to afford/enjoy the same hobby for themselves? Amateur astronomy beyond a simple small telescope or binocs isn't cheap and can't be done by those of us living in bright cities. I'm quite a few miles out of downtown in my city, and still can only see less than 100 stars any given night. Sometimes it's as low as 20. I'll never forget stargazing when I took a cruise as a teenager. I was truly stunned in awe for hours & spent every night up there on the top deck just chillin with my other nerd friends finding constellations we knew were supposed to be there but had never seen before.
@@djvapid to see the pictures
I've been waiting for the day Mario Kart would be used in a physics analogy! 🙏🫶
One of my favourite voices on youtube! Alex you describing anything grips my ears and makes me fall into the world your describing! i'm 53 and have documentary's my whole life (Attenborough my God) and your narration style is up there with best on youtube hands down! Continue your work son you've nailed it!
Honestly we shouldn't be worried about any astronomical events. If a cosmic extinction-level event is coming it's probably better not to know.
Nor would NASA or the powers that be would tell us? For obvious reasons!
There is no use burying your head in the sand...
While your sentiment might reflect a common fear of cosmic extinction-level events, it's crucial to approach such assertions with a careful consideration of scientific evidence and preparedness measures.
Firstly, dismissing concerns about astronomical events, including the potential impact of asteroids, could undermine proactive efforts to safeguard against such threats. Initiatives like NASA's planetary defense programs, including recent trials aimed at redirecting asteroids from collision courses with Earth, demonstrate proactive measures to mitigate potential risks. For instance, NASA's Double Asteroid Redirection Test (DART) mission aims to test the effectiveness of redirecting an asteroid's trajectory by impacting it with a kinetic impactor.
However, it's essential to recognize that while these efforts demonstrate technological capabilities, they do not eliminate the need for ongoing monitoring and preparedness. The impact hazard from asteroids and other celestial bodies remains a real and significant concern, and continued investment in detection, tracking, and mitigation strategies is essential for ensuring the safety and security of our planet.
Regarding the suggestion that it might be better not to know about a cosmic extinction-level event, such a stance raises ethical and practical considerations. While uncertainty and fear surrounding catastrophic events are understandable, informed decision-making and preparedness are critical for minimizing potential impacts. Ignorance of impending threats would leave humanity unprepared and vulnerable, with potentially devastating consequences.
@@twobrainedserpent Thanks, ChatGPT
@@ChristophersMum I bet this persons head is firmly planted already.
💫 In my youth (1970s ) I saw quite a few Quasar TVs 📺 At the time I had no idea what the Quasar name & simplistic logo ---|--- represented .
.
From what I've read, use of the name Quasar began in the mid 1960s
Very interesting episode! Thanks to you and your team for producing these!
Didn't we know about this quasar? There were articles about detecting massive radiowave beams, a few years ago.
You might have, but I didn't. And I'd suspect most of the world didn't. We are not ALL astrophysicists.
Can you accept that quasars are newborns from host galaxies? The redshift anomaly is from their unique plasma density. They are not distant.
@@efdangotu I can accept it, I was just asking a question. Why would you assume that i wouldn't accept that fact?
@@dynad00d15, not an apologist for bad attitudes, but reddit has taught me that the majority of English speakers--more so native than non-native--have very little depth when it comes to context of their word choice.
I'd expect different in a thread about quasars, but then, astro-physicists and their fan boys aren't necessarily known for their people skills.
@@macblastoff7700 I can understand your frustration, but It's incredibly presumptuous and arrogant to generalize an entire group of people, especially based on a limited experience or exposure like Reddit comments. Implying that English speakers, particularly native speakers, lack depth in their word choice is not only ignorant but also generally insulting.
Furthermore, insinuating that astrophysicists and enthusiasts lack people skills is just plain disrespectful. These are individuals who dedicate their lives to understanding the complexities of the universe, often communicating their findings with precision and clarity.
What really gets to me is how utterly pointless this comment is. It doesn't add anything constructive to the conversation about quasars or anything else. Instead, it just spreads negativity and reinforces harmful stereotypes. And let me tell you, it's exhausting to come across comments like this when you're genuinely trying to learn and engage in meaningful discussions.
But what really baffles me is why someone would mention their expectations just to knock down the same thing they're trying to stand for. It's like shooting yourself in the foot. If we're advocating for understanding and respect, let's actually embody those values instead of undermining them with thoughtless remarks. We need to create spaces where everyone feels welcome to share their insights without fear of being dismissed or belittled. That's how we can truly foster a culture of learning and mutual respect. Peace and love.
"Shedding light on the production of photons." I see what you did there :)
RIGHT ON! SO Excited to see this done by Astrum and narrated by you Alex.
Thank you.
So, they're scattered straight _into_ Compton 🤔
Real Muthuphukkin Squeez ...
5:33 Man, I forget how incredibly vast the galaxy is at times. To think an entire galaxy is rotating around such a small dot in the center is just mind blowing.
I must say that your narration-- your voice-- are very enjoyable to me and I'm sure many others. A real intelligence and sincere eagerness for this material shines through.
Very nice! Thanks very much.
When I was a little girl I got an astronomy dictionary, and I don't recall it saying "quasar" was a "quasi-stellar radio source," it said "quasi-stellar object." I didn't know that the radio part of the e-m spectrum was important for a quasar till I watched "The Quasar Enigma" from "How the Universe Works," prolly my favorite episode of all (I've seen it innumerable times!)
Thank you for introducing me to the charming aspects of space!
Also I love the irony that we detected the first microquasars within a year of discovering Cygnus X-1 but it would be about 14 years before there was concensus that it was '95% change it's actually a black hole' (quoting Prof. Hawking haha). Science is fun like that sometimes.
you are most likely seeing a typical neutron star. neutron stars tend to have appearances similar to quasar. with electrons forming a halo around it(because they cant go between the neutron star core body anymore technically making it a gargantuan single atom). and the gravity emission at the polars excites the electron ring that are lit by it and produce a visible weird light pillar effect. which again, makes it looks like quasars. but its not.
mind you quasars dont start small.
No, these are stellar mass black hole microquasars.
@@tonywells6990 you are making things up from picture that being taken from far away. its a neutron star you are seeing. there is a massive blackhole in the center of the galaxy, quasar doesnt start close to a giant black hole. and distance from witnessed quasars from nearest galaxy/nebula victims must be nearly twice the nebula's own diameter. its so easy to see space picture and making wild claims. bad habit of earth astronomers of calling things they saw whatever they want like people who spy on other people on a building a kilometer away using a telescope and making up story and assumptions about the person they spy on without knowing their lives.
Loved it…. Thanks for creating Alex and team… 😎
I'm seeing it more and more lately, creators are using the screen to ask for things like patron or show ads and I don't mind it. It's far less disruptive than halting an interesting video to do an ad or ask for memberships.
This is an improvement. I just hope other creators don't take it to the extreme and make it invasive like ads of the past.
Fantastic video. I'm currently doing my honours thesis on observations of TeV gamma rays from AGNs and GRBs. The only thing I would have added is the contribution of synchrotron to charged particle acceleration within the jets, especially as it tends to be more dominant than Inverse Compton within AGNs. Otherwise, you covered everything necessary. Great work.
I miss when astrum wasn't a clickbait content farm
Weird take
The should we be worried was unnecessary
@@DataC0llect0rnot at all
It's yourube as a whole, everyone has some sort of clickbait title
It should be clarified that a thing is considered clickbait it is when it promises one thing and delivers another …this video is technically clickbait. There are NO ACTIVE QUASARS in the Milky Way. There are X-ray binaries which are NOT QUASARS but a small stellar mass black hole accreting matter. So yes this is clickbait
Space is the most fascinating thing to me. The mind bending phenomena out there make me so excited to learn more. This is truly what I want to do with my life; I want to learn everything there is to know about the mysteries of space. Especially black holes, they are the most enigmatic and fascinating objects in the universe to me
Inverse Compton Scattering..
Straight Out Of Compton!
The boys in the hood are always hard
Having two sets of jets is even more counterintuitive as Hawking radiation originating light years away from a black hole's event horizon. Strange and interesting.
Electromagnetism explains a lot.
Two jets is just conservation of angular momentum. If it was one sided it would accelerate the black hole no? Jets have nothing to do with Hawking Radiation (We think; No one actually KNOWS what causes jets because only radio loud feasting black holes make them. Why are some feasting black holes radio loud? 🤷♂). Hawking radiation is the hypothetical black body radiation of a black hole and it required a math trick.
All objects that have temperature emit light. We humans emit infrared. Figuring out "why hot thing glow that color" was a huge step in our understanding of quantum mechanics. Hawking "found" this radiation by examining quantum fields infinitely far away from the black hole. Basically a limit if you're familiar with basic Calculus.
@@TheWizardMyr Did you even watch the video? No calculus required. There are two SETS of jets, one set starting at the event horizon that end a few light years distance and a second set that start 25 light years away from the black hole, extended to 300 light years.
@@araarashinigamiListen to what he says after he describes that. No one knows whats goin on with jets. We may just not be able to see what's happening in the supposed space between because of something as simple as dust between us and this quasar obscuring this part of the jet. Notice it is this specific quasar that this is occuring at, not a set of quasars that we've observed this at?
I'll admit I probably misunderstood your comment, however, the topic of jets in general is something that is not well understood and is an field of active study. Could you clarify what you were suggesting? Were you suggesting that the secondary jet supposedly starting farther away is Hawking Radiation?
@@TheWizardMyr That makes so much sense, I never thought about it that way. Without the counter balance of the two jets. Black holes would be traveling. Maybe even reaching velocities a fraction of C or more
I rewatch your videos they are that good, some bring me nostagia from treasured times in my life, so thank you for that!
JWST has been SO worth the trouble.
Loved the show. Thank you for the 411.
This was a fun & interesting video, keep up the awesome work.
What a beautiful universe we live in... Cannot be amazed enough by all of this.. Great video as always! 🔥🌟
Woah a lot of this is new information to me ( minus regular quasar stuff ) great video
Further is a measure of degree. Farther is a measure of distance. More light years away would be farther, not further. Not only on this channel, but others as well, I've been pained hearing this repeatedly for years.
Outrageous 😮
As usual, excellent vid.
Good stuff! 👌👌👌
I just finished taking a long exposure of the Needle Galaxy and saw a few Quasars identified in the area. I didn't know they were in our galaxy but I can see why they would be since a black hole can form near a companion star. I guess a gamma ray burst is a black forming inside a massive star before the outer layers are blown away. That black hole is eating the star before it even fully explodes.
I was intrigued to find out that the energy increases as it leaves and that it increases hypothetically ,to presumably, greater than the speed of light . What a concept!
*Less than the speed of light.
I always saw quasars as these overwhelmingly powerful objects. So to learn you can have scaled down versions in our own cosmic neighborhood was quite a surprise.
I thought a quasar was specifically defined as an active galactic nucleus? Have they expanded the definition to cover any active black hole?
To all the people dismissing this video as click-bait, I implore you to actually watch the video. Microquasars are the stellar equivalents of Quasars. Whatever you call them, be they Quasars, Microquasars, Blazars, etc., all are simply black holes that are actively devouring enormous amounts of stellar and/or interstellar material in a process known as accretion, which superheats it and causes it to emit enormous amounts of radiation in the form of blinding light, Radio waves, X-rays and Gamma rays concentrated into twin hyperenergetic jets. How bright they appear depends on the distance, orientation of the jets and whether they are stellar black holes or supermassive ones (Active Galactic Nuclei).
I'm sorry. I missed the "micro" part of microquasar in the title. I'll go back and re-read it.
Yeah, no.
There are no quasars in the Milky Way.
Microquasars - although carrying a similar name and probably being based on similar mechanisms - are not Quasars.
They're tiny cousins - nephews, if you will - of Quasars, but they do not belong in the Quasar category.
(For starters, they don't appear as point-like objects, so don't qualify as Quasi-Stellar.)
First time hearing about mini quasars in the milky-way 🌌
That's because it's complete nonsense.
Fascinating episode, wonderfully narrated. Magnetic pulses are something new to add to behaviour of particles in space.
Great channel, subbed
Fascinating!
Tiny quasars?
We’d be dead or never extant if there was an actual fucking quasar hosted in our galaxy.
What’s going on with Astrum these days 🤨🤨🤨
I wonder how fast one of those micro Quasars could cook a Chicken? Just trying to think of a practical application for them.
Finally somebody is asking the real questions!
570quadrillion years
How hot is a quasar in terms of slaps per second?
Inverse Compton Scattering occurs when Electrons with Attitude are in the house.
(sorry...) :)
This happens when cosmology nerdology and rap nerdology intersect.
Side note: Love this video Alex. One of my favorites so far. (next to anything else black hole related, or outer ice giant planet videos)
Best physics joke ever 😂
Basically, all existence, for us, is an explosion slowed down to a near standstill and all of the debris in the explosion is acting according to physics. Our entire existence begins and ends in a minute fraction of time within our reality and as a blink in the big bang explosion. Since our lenght of time is so extremely finite, do we really exist?
If you want to see the image of the "spotted" quasar, go to a different video. Alex won't show us.
Really enjoyed this Video Guys, well done !
The F are you going to do?! Should we be worried, pfft, LOL!
I think the most surprising thing is actually how far we have come from not knowing to building an understanding of quasars.
"To accept the things I cannot change; Courage to change the things I can; And wisdom to know the difference." That's the answer to the question of "Should we be worried?"
you know the simulation @11:30 reminds me of what a cell dying under a microscope looks like. it slowly stops moving, and its cell wall bursts open spewing everything outward. just with space the reactions are on such a large scale.
So, how are these microquasars different from regular black hole action? Is every black hole scarfing down stellar matter a (micro)quasar? Or is there a difference?
Quasars tend to have very active accretion disks and their characteristic relativistic jets. Blackholes with less active accretion disks (or no accretion disk) and no relativistic jets are not quasars.
Whenever active galactic nuclei are mentioned we're contractually obligated to ping Dr. Becky Smethurst lol.
I love quasars. I tend to buy a family share pack at the supermarket and my favourite flavour is smoked BBQ beef.
Quasar tax incoming
i be lookin at scary space news and being scared for the entire day and forgetting about it in a day
Learning there’s quasars in the Milky Way made me think of that one episode of Star Trek The Original Series when the Enterprise was investigating Murasaki 312 in the TOS episode The Galileo Seven.
A list of the other micro-Quasars would be nice.
I am a Quasar. It's literally in the name :-D
This was a great video. Quasars that we can study closely? Ohh Yeah! Thats HUGE!
We can learn so much about how the process works and reveal how quasars from supermassive black holes work.
I have to be honest, the most surprising thing I found in this video was that full sized quasars aren’t even present in our galaxy. Much less ubiquitous, relatively speaking of course. That was cool to learn. But this is the first time I’ve heard of mini quasars.
I thought quasars were active galactic nuclei. Thanks for clarifying that they are really just a weird radio astronomy observation...and can be 'mini'. I didn't know that...
The main thing I notice from the first image is the big showing of the PSF, which sends me into a stress spiral because the PSF for the MIRI MRS is STILL broken and 50% too small ;-;
"would you believe me when I tell you we have the best of both worlds, quasars in the milky way that we can see and study without it destroying us, but you might ask *how can that be possible?!* it is possible, thanks to our sponsor Quasardash, bring it right to your doorstep"
How is stellar fusion affected in the giant stat when it has a massive (stellar or collapsed) partner? What constitutes the center of fusion when there are tidal effects? How does a stellar object's fluidic body orbit its center when that center is offset by a massive companion? Does that offset have impacts on the growing layers of fused materials as the star ages and passes through age-phases?
I love quasars, they spin so fast, as a child I always wanted one in a frame above my bed...
SagA* wouldn't pose any threat to Earth if it was a Quasar. It wouldn't have even been discovered until all the other Quasars were found. It would have to be within 33 light-years, where it would look like a second sun, to pose any harm at all.
Bro never disappoints🤗👍 thanks for sharing 🙏
I love the Mario Kart analogy! 😂
We got Quasars in our galaxy before GTA6
Nothing to worry about. Nothing has happened till now and that quasar has been around for as long as the galaxy we revolve in.
Expectation: alien radio
Reality: nature's death ray
I can bet on my life, that in 10 years nothing in this video will be relative anymore.
These space channels gotta stop the gaslighting. People will still click if the title doesn’t make you think you’re gonna die. Space will always be fascinating. Just roll with that.
I generally run around in fear of what lurks in the cosmos -- human beings topping my list, of course.
What surprised me was the click bait here and the fact that people only just realised there are small quasars in the Milky Way. There are a lot of small everything’s in most galaxies, and I thought it was gonna be a decently sized quasar, but no.
Well said
i feel like unsubscribing
I didn't mind being "click baited" into learning about these micro-quasars. I sort of guessed it had to be about tiny quasars from regular stellar-mass black holes.
yeah i was thinking the same , he calls them quasars but they are just small active black holes, quasars are specifically entire galaxies with active nuclei.
Meanwhile there are 8 billion human beans on Earth and 90% of them are still learning about todays understandings of space. get over yourselves
So when will we get a telescope that can actually view the individual objects there? As a complete object and not a blurry disc?
When an electron is bound to an atom, it can only have certain discrete energy levels... is that true of all electrons, or only those part of an atom?
Build a sphere around it and generate energy
Thanks, Alex! ✴
Milky Way got its SMBH from Teemu.
So basically every video is clickbait now eh.
hi, could you please explain more about why the we observe the shock zone with complicated magnetic field? I mean why we have such magnetic field?
If it ends up being a Quasar dragon we should prepare for the end.
Here after 23 hours this video was posted, James Web discovered 2 black holes merging lol
Can diffusive shock acceleration be utilized in a spacecraft engine? This seems similar to a laser - a gamma ray laser?
No, you shouldn't be worried. I just saved you 15 minutes. You're welcome.
This channel isn't for you
Thank god for the comments only wasted 30 seconds before seeing the click bait warnings
@@unitc87 k good talk
Not even entertaining your advice
Thanks g
I love things about space but if I watch too much about it it gives me the Heebie-jeebies.
I would have named Quasars "radio stars", lol
quaze it up, we did it milky way bros
Milkychads stay winning
14:00
There is another dowside to full moon: It prevents you from seeing faint stars.
11:56 Are these "complicated configurations of magnetic fields", like, similar to our particle accelerators? If not, can we make one? A shock-wave particle accelerator space rocket accelerator etc?
Have you heard about quasar J0529 - 4351? This is a huge discovery, because this object is 12 billion light years from Earth! If you compare this quasar with our sun, it will be up to 500,000 billion times brighter. That's right, you didn't hear wrong.
