The runaway black hole may help to answer what came 1st the black hole or the galaxy, is the star trail behind it newly formed stars or ones getting sucked along with it in it's draft?. To me this discovery is huge and could answer a lot of questions on galaxy's and there black hole centers and even the big bang. If we say there new stars that could mean we are seeing the 1st stages of the spiral forming around a black hole ( I'm guessing that the black hole would be spinning is some direction ). Or if the stars behind it were just sucked along with it when it was ejected this could give more info on how black holes react with objects around them with out lots of stuff around them, i.e. we know where it is and we can see how fast it pulls in stuff. So I'm no astrophysicist, and I know little about space beyond the photos I take, just me and my wondering.
I couldn't help but notice on the NASA image you have at 10:13 that the Earth's rotation time is 23 hours and 56 minutes, NOT 24 hours. Why is that? Wild speculation follows: Does it have to do with the planet traveling on its orbital path around the sun? Does it mean that in order to get a point on the surface of the Earth to return directly under the Sun after one rotation that it has to rotate more than 360 degrees? Does it take 4 minutes extra time to make that over-rotation? So, does this chart state that a 'day' on Earth is actually more that 360 degrees of rotation? It suggests its closer to nearly 361 degrees? (Based on a very crude comparasion of: 360 degrees in a circle, or orbit, and 365 days, or so, to a year to make the orbit.)

It's not just what you're explaining, it's the way you come across- light-hearted but a technical expert and professional in your field. I've enjoyed your channel for a long time and I'm grateful you make time even during your travels to keep up with your regular features like Night Sky News.
That title hooked me. Space is frickin wild!! Blackholes getting ejected from galaxies and whatnot. And OMFG that GRB to Sun power ratio blew my mind beyond comprehension!!!!
I heard if a quasar went off in a distant galaxy and it just happened to be lined up with earth, all life could be wiped out and we wouldn't even realise it. Extremely unlikely to happen, far more likely we'll get hit by a big rock before then, but it's hard to fathom how big the universe is at some point the numbers are too big to comprehend. It's pretty amazing though.
Excellent coverage as always! Just one glitch I spotted - in describing the way a lunar eclipse looks, it isn't the Earth's atmosphere that makes the edge of the Earth's shadow at the Moon "fuzzy;" it's that the Sun is an extended (i.e., not a point) source of light, being about half a degree in apparent diameter. Speaking of eclipses, we're 12 lunations (just under a year) away from the second "Great American (Solar) Eclipse," on Apr 8, 2024. Although I'm not much of an eclipse chaser, I'm already starting to get excited! And BTW, welcome to N. America (Toronto & Huntsville, home of Marshall Space Flight Center)! Fred
Good news, the echo isn't terribly distracting 🙂 On the BOAT GRB, it's interesting to see they realized that the sensor peaked out and reconstruct the full intensity.
I agree with this. I definitely heard it at first, but this was mainly because Becky almost always presents from her home and I'm used to that acoustic with her vids. After a few minutes of being focused on what she was explaining, I didn't hear the different acoustic effect any longer. The human brain will adjust visual, audio and olfactory inputs to a new norm when necessary. No need to bend over backwards in a hotel room with blankets and such. Sometimes, you just gotta roll with what you got.
Thank you for continuing the legendary work of Jack Horkheimer, the star of the PBS series Star Gazer. Hearing you use the same phrases and similar presentation styles instantly brought me back to my youth when I would record PBS on my vcr just hoping to catch a Star Gazer episode. Keep Looking Up 💫
To give you an idea of how bright the GRB is ... we're still detecting it. Like today, six months later. Usually, Swift can only detect GRB afterglows for hours to days. Maybe weeks.
I've always been fascinated by space and Dr. Becky has allowed me to notice more amazing things in the night sky with these videos. Love the Swift cutaways btw!
The images of Uranus are wonderful!! Our immediate neighbors are certainly beautiful!! I always think - we don't even know what we don't know. It's so exciting to see something new - the apparently ejected object is fascinating!!
The comfortable, cosy setting of your home is perfect for your Night Sky News.. but.. I dunno.. that bright, sunny setting was so lovely!! The echo-ish sound too made it feel more like we're sitting with you in that apartment. No need to change what works, of course.. plus sunny days in England don't exist, right?? But it wouldn't be a bad thing if you ever decided to do the occasional video in similar settings to this one! 😊
The difference between the umbra and penumbra in Earth's shadow is best thought of if you imagine yourself standing on the Moon looking back at Earth. If you see a total eclipse of the Sun you are in the umbra. You are also seeing all of the sunrises and sunsets on the Earth in the red ring around the Earth caused by the Earth's atmosphere (which also causes the Blood Moon). On the other hand, if the Earth blocks only a portion of the Sun you are seeing a partial total solar eclipse and you are in the penumbra of Earth's shadow.
Dr Becky, you're like the new version of Sky at Night (I loved that show when I was a kid), because you've got another level of passion on top of Patrick Moore's restraint. I love watching science communications even though I don't have the mind to be able to fully focus on it, so I admire people who are so passionate about the things that affect us all. I'll get back to designing interfaces that enable the rest of us to use the discoveries of science.
Thank you for another informative and interesting look into the universe. I'm currently studying 1st year Astronomy and I appreciate how you're tying in what you're presenting with what I'm learning ie electrons moving between states and ejecting photons. It's great to see real life examples of classroom presentations.
When a random event like this occurs, how do instruments, such as Hubble and JWST, get assigned to have a look at it? Since their time is scheduled in advance, who decides to change the schedule? How is it even requested?
How is it commanded? You can’t just say point it there….or can you? Are the command put through a simulator first? How’s the commutation done? We need to know
Don't worry about UV coming through your hotel window. Ordinary float glass (a.k.a. green glass) is very good at blocking UV. At 300nm, you can expect 1/8th inch glass to block around 99.9% of light. It will still block 99% down to 260nm. (And if you're wondering, I did just measure it on my photospectrometer.)
Great to know, I am a victim of skin cancer so information like this is well handy. I did have to look up spectrometer, but I am guessing I would not be the only one.
@@JamesJordanson I don't know the regulations where she is at, so take this with a grain of salt, but I suspect it is laminated glass, meaning a minimum of 1/4 inch total glass plus the polymer sandwiched between the glass plates. However, it is possible PMMA satisfies local regulations, so it is possible that the window isn't glass as I assumed. Even if the window is PMMA or some other polymer, I would expect it to have UV inhibitors in the polymer, if not to protect the polymer itself (I know PMMA is better than vinyl, but I don't remember if it is completely immune to UV damage), then to protect what is behind the window. Regardless, it is a fair point you made regarding my assumption that the window was glass.
If the scenario is indeed that two black holes orbiting on their way to merge ejected a third one coming in, it's a rather funny situation. Like, EXCUSE US, we are trying to MERGE over here! Screw off!
the crazy part is, that black hole was still only traveling 1.19% the speed of light, which don't get me wrong, very fast. but for such a dramatic event it really puts in perspective the difference orders of magnitude present
Great video as always, but a slight misspeak . You refer to gamma rays as having the "highest wavelength" (around 12:37) but I think you mean highest frequency (i.e. shortest wavelength).
In a galaxy far, far away Something strange happened one day A black hole that once sat at its core Was suddenly kicked out, leaving everyone in awe The galaxy was in a state of confusion As they watched the black hole's ejection It was a rare and wondrous sight A cosmic event that filled them with delight The black hole spun and twirled away Into the vastness of space it did stray Leaving behind a galaxy in wonder A new beginning, a cosmic thunder The stars shone brighter than ever before And the planets danced in a cosmic uproar The black hole's absence brought a new light To a galaxy that was once cloaked in night So let us gaze upon the stars tonight And marvel at the beauty of this sight For even in the depths of space There's always something new to embrace.
fast moving rogue super massive black holes could be slightly problematic. granted at only 0.5% of c you'd see it coming from quite a distance. A galaxy weight black hole could make a mess of things.
If it's moving that quickly, I don't think it'd stick around long enough to cause any large-scale gravitational distortion. Probably just capture or eject a few stars along its path and maybe throw out some intense radiation from the accretion.
@@BenAlternate-zf9nr 0.005c would be 900 years from alpha centauri to here which is a considerable amount of time for a multibillion sun mass black hole to mess things up. I don't think you quite appreciate the scope of how antisocial such a thing is :)
Excellent video Dr. Becky! This week's space news is very interesting. I loved the references to 1997's Titanic when you were talking about Uranus' year and your reference to Taylor Swift's Anti Hero when you were discussing the B.O.A.T. GRB!
Not only could I listen to her all day, but she explains things in a way that a layman can understand and comprehend. I could also stare at those beautiful eyes and gorgeous hair all day.❤
that’s just what I need right now. I was thinking earlier this evening that you might post a night sky news video tonight. And I just looked at my phone and I got a notification. Im so excited. I studied the entire day for my final exam. My head needs some free time haha. (a random German says thank you;))
Would one eventually develop from enough stars turning into black holes? Would the ejected super massive black holes find new homes in another galaxy? If they do and say the black hole attaches itself to an arm of a spiral galaxy, what effect would it have on the arm?
Usually matter is attracted to the core of a BH and a simple explanation, all the neutrinos would be consolidated into one giant 'ball'. The rest of the turbulent dynamic is fantastical to contemplate 😇
Becky, you manage to bring the perfect mix every time IMHO: Clearly sensible utter enthusiasm for the matter, serious knowledge, tons of work put into it, a gift for transporting it to the public in a very enchanting way, humor - you name it. Thank you for all of this and much more. Be safe, keep going, live long and prosper.
20:20 I wonder if said galaxy has a massive black hole in the middle of it as many do. Here is why I wonder that. Eainsteins Time dilation is the slowing of time as perceived by one observer compared with another, depending on their relative motion or positions in a gravitational field. To a distant observer, clocks near a black hole would appear to tick more slowly than those farther away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it. (is the polarity true as well when escaping a black hole? hmm. Curious.) Why does this matter? If one could orbit a black hole time would move slower for them (it is a time machine) in this sense. Imagine if that "streak" is a space craft! that was leaving such a time traveling journey!!!!! Might it look something like this? 20:20 Also White holes are theoretical Cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole nothing can enter a white hole. Truth be told white halls. Could this be a whitehole/hall?! Like the Chandra xray images. Very interesting! Because in that case. Something Escaped A Black Hole at almost the Speed of Light and NASA Recorded It. Captured at the Chandra X-ray Observatory Center in collaboration with the Harvard-Smithsonian Center for Astrophysics, a system with a black hole and companion star about 10,000 light years from Earth was caught by astronomers. They have captured a stellar-mass black hole hurling hot material into space at close to the speed of light using four Chandra observations in 2018 and 2019. Upon hearing that a Black Hole is spewing out material instead of sucking it all up, one might stand in a puddle of confusion. It begs one to ponder that perhaps they’ve located a white hole instead of a black hole. White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, (we think lol) nothing then can enter a white hole. (we think lol) Truth be told, white holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. More recently, however, some theorists have been surmising that these twin vortices of spacetime may be two sides of the same coin. To get a better understanding, let’s tune-in to theoretical physicist at the Centre de Physique Théorique in France, Carlo Rovelli. He asked audiences to imagine floating in space in a high-tech spacecraft observing space. From afar, a white hole looks exactly like a black hole. It has mass. It might spin. A ring of dust and gas could gather around the event horizon, and just as usual, the bubble boundary of the black hole separates the object from the rest of the universe. But if the space travelers kept observing, they’d eventually realize the supposed black hole give a hearty belch. Carlo Rovelli says, "It's only in the moment when things come out that you can say, 'ah, this is a white hole.'" So, when the Chandra X-ray Observatory Center framed graphic optical and infrared images of the space area called Maxi J1820+070, and data revealed that two jets pointed in opposite directions, launched just outside the event horizon of a black hole, shock spread across the field. Here are the details of this shocking find. Waiting for us. Here’s the vital notes of the eternal mysteries of space. Here’s the best place to learn about the infinites of space. This is an opportunity for us. We can take JWST and expand upon their research thanks to innovations in recent years Our hopes are high and our faith is placed in JWST's capable proverbial hands. We wait with baited breath for News on its adventure!
I'm not sure why, but my first thought was that some hyper-advanced civilization was lobbing this black hole at an enemy galaxy! Anyway, great video Dr. Becky, love your work!
Questions, can JWST can see tru the galaxy and see the other side of it??? And it will have new observations of previous black holes to get new data on them???
It’s just a little scary to think, there could be a super massive black hole m, speeding through the universe, heading towards our solar system. Unlikely, I know, but I guess now proven possible by this observed event. 😮
At the end when you say that according to our current understanding, you can remove the black hole in the milky way. I did thought for a moment that you'd say "but please don't test that until we've observed more cases" 😂
13:06 Now I hate to be that guy. But I can’t take this anymore. Don’t GRB’s come from Hypernovea, not Supernovea? Unless that’s outdated information. I’m very confused. As that’s what I’ve heard my whole life. I learned it from a space documentary series called “How The Universe Works”. Which is a great show, I definitely recommend it! But, yeah. I’m just confused. Also, that show also said that, only Supernovae made Neutron Stars, while only Hypernovae made Black Holes.
The idea that a gamma ray burst lasting milliseconds can put out more energy than the sun over 6+ billion yrs is just crazy and mind blowing... It's just WOW, huh, OMG, WOW....
Thank you for coming to TO and on a nice Week. I hope every moment goes great and you have a safe trip back home. I love your knowlege and also the relaxing style that you tell us of the astro news. I am slowly getting your book read. I am on ch.4 why black holes are black.
Wow, cool af, I love Uranus and supermassive black holes. My science school teacher gave me detention for admitting this. I wish I could show her this video to explain these are things to love. Btw, your passion for science is amazing.
Whats Chandra up too? We dont hear much about the XRays. You know that B left me before we even got together. And with my Best Friend, whos not my best friend anymore. I get no respect, I tell ya
The ejected black hole got me thinking about something. I'm aware a number of galaxies have been found recently with no dark matter. Do you happen to know if they lack a super massive black hole at their core?
I bet growing mushrooms on the moon could at least be easier with greenhouses without any wind factor, and less frequent replacements in the shade, while different kinds of plants can be more self sufficient in the sun, like prickly pear cacti, and beans can be good at putting nitrogen into the soil, with ph of lunar soil being high for many plants typically, and without oxygen on the moon? I'm sure liking this alkaline water at the water store with calcium, magnesium, and other minerals though.
Hi Becky you got to be the most exciting girl that I had ever found in RUclips. Your are the coolest one and I like all your videos. They are all so interesting and informative. Keep on posting new videos.
Becky i look on RUclips all the time for content like this i have for years and finally i find you in 2023 my brain has ignited its theoretical part again, thank you so much,. ❤
I have a theory about the afterglow.... could this object be old enough to have emitted the burst whilst expansion of the universe was still more rapid than it slowed to? i.e. surf the expansion wave, not dissipate according to usual rules of radial distance from source etc....?
Did not enjoy reading The Three Body Problem but it was a horrifying glimpse at what life might look like clinging on by fingernails in an unstable system.
I liked that observation of the second black hole being ejected in the opposite direction, But I was wondering if there is a name for the stability of pairs of bodies ("rule of two" - Star Wars reference)? Also, is there a distinction between the use of the term Collaborators and "et al" in Astronomy, or are they synomous?
@@DrBecky Thanks! 🙏I've been thinking about getting one for a while and your video finally convinced me. I just wanted to make sure to use your affiliate link to support your endeavors, because I truly enjoy the videos you put out!!
Wow these ejected black holes are so cool!! The turbulence of them plowing through the intragallactic medium is causing star formation even! Reminds me of Merrifield talking about galactic spiral arms ramming gas together to cause star formation. Loved having Becky talk about this but would also love to hear what Mike has to say!
ive sused it gamma ray burts are space ships (light/warp/paradox prevention) kinda of sonic boom but with faster then light travel. so like if you made a loud sound and then travelled faster then sound in the direction of the sound wave the sonic boom would eliminate the wave as it travelled so you wouldnt be able to hear it. the same type of thing happens with light but instead of a sonic boom you get a gamma ray burst. so you cant see where your going to be , or your self after you leave. big guess but makes sense to me
I think the penumbra is not because of earth's atmosphere. It's because of the sun not beeing a point light source. (Or is it a combination of this and the atmosphere?)
I'm curious what you think about the new image of the M87 black hole. Some online comments were criticizing it, but it seemed reliable to me, which is why I'm curious for expert opinions.
Me being on a mild exo-weather jag right now, kinda wondering if Uranus' "snow cap" might actually approach solidity. Obviously, not remotely close to a full ice, but is there even a remote possibility of something like a loose aerogel mass accumulating at that level? Know any people or sites to point an obvious noob like myself at?
Sorry if this has already been mentioned but the "previous video on the effect of removing the Milky Wy’s supermassive black hole - " has no link in the description. Awesome video though! Its amazing that the ejected black holes spawned star formation in their wake. Would these regions be considered new dwarf galaxies or part of the original? Space is awe inspiring.

But I'll put it in my watch queue and inevitably, I'll get caught up in what you're explaining. It's not just what you're explaining, it's the way you come across- light-hearted but a technical expert and professional in your field. I've enjoyed your channel for a long time and I'm grateful you make time even during your travels to keep up with your regular features like Night Sky News.
This means the world to me, thank you for sharing 🤗
That title hooked me. Space is frickin wild!! Blackholes getting ejected from galaxies and whatnot. And OMFG that GRB to Sun power ratio blew my mind beyond comprehension!!!!
Holy shit i didn't realise gamma ray bursts could emit THAT MUCH ENERGY! Woah. That's unimaginably energetic
Crazy right?! 🤯🤯🤯
@@DrBecky Black Hole: "Now for my next trick ..."
@@DrBecky Hi Becky! I was wondering if the planet could be destroy if one from our own galaxy would aim at us. Thanks
I heard if a quasar went off in a distant galaxy and it just happened to be lined up with earth, all life could be wiped out and we wouldn't even realise it. Extremely unlikely to happen, far more likely we'll get hit by a big rock before then, but it's hard to fathom how big the universe is at some point the numbers are too big to comprehend.
It's pretty amazing though.
Truly the BOAT.
Nice to see you on this side of the Atlantic (and just across lake Ontario from me!) Great video, as always!!
Excellent coverage as always!
Just one glitch I spotted - in describing the way a lunar eclipse looks, it isn't the Earth's atmosphere that makes the edge of the Earth's shadow at the Moon "fuzzy;" it's that the Sun is an extended (i.e., not a point) source of light, being about half a degree in apparent diameter.
Speaking of eclipses, we're 12 lunations (just under a year) away from the second "Great American (Solar) Eclipse," on Apr 8, 2024. Although I'm not much of an eclipse chaser, I'm already starting to get excited!
And BTW, welcome to N. America (Toronto & Huntsville, home of Marshall Space Flight Center)!
Fred
Yep. The red coloration comes from Earth's atmosphere, but the partial shadow area is just where the Sun's disk isn't fully covered.
@@BenAlternate-zf9nr As seen from the Moon. Exactly.
Good news, the echo isn't terribly distracting 🙂 On the BOAT GRB, it's interesting to see they realized that the sensor peaked out and reconstruct the full intensity.
Becky, you can reduce echo with blankets or towels hung or laid out just outside the frame. You can probably also rent acoustic panels.
They might have been more concerned that the sensor broke.
@@zen1647 For a one time hotel room recording is it really worth it? Content matters more to me than audio perfection.
What echo?
I agree with this. I definitely heard it at first, but this was mainly because Becky almost always presents from her home and I'm used to that acoustic with her vids. After a few minutes of being focused on what she was explaining, I didn't hear the different acoustic effect any longer. The human brain will adjust visual, audio and olfactory inputs to a new norm when necessary. No need to bend over backwards in a hotel room with blankets and such. Sometimes, you just gotta roll with what you got.
Thank you for continuing the legendary work of Jack Horkheimer, the star of the PBS series Star Gazer.
Hearing you use the same phrases and similar presentation styles instantly brought me back to my youth when I would record PBS on my vcr just hoping to catch a Star Gazer episode.
Keep Looking Up 💫
To give you an idea of how bright the GRB is ... we're still detecting it. Like today, six months later. Usually, Swift can only detect GRB afterglows for hours to days. Maybe weeks.
Hey you're in Toronto!!! You are an honorary Canadian now! That's how it works, it's that simple!!! 🙌
I've always been fascinated by space and Dr. Becky has allowed me to notice more amazing things in the night sky with these videos. Love the Swift cutaways btw!
The images of Uranus are wonderful!! Our immediate neighbors are certainly beautiful!! I always think - we don't even know what we don't know. It's so exciting to see something new - the apparently ejected object is fascinating!!
How does a super massive black hole get ejected, when it is literally the centre of its galaxy and everything orbit's around it !!!!!
By ANOTHER supermassive black hole 🤯
@@DrBecky Ah right, now I get it lol .
The comfortable, cosy setting of your home is perfect for your Night Sky News.. but.. I dunno.. that bright, sunny setting was so lovely!! The echo-ish sound too made it feel more like we're sitting with you in that apartment.
No need to change what works, of course.. plus sunny days in England don't exist, right?? But it wouldn't be a bad thing if you ever decided to do the occasional video in similar settings to this one! 😊
The difference between the umbra and penumbra in Earth's shadow is best thought of if you imagine yourself standing on the Moon looking back at Earth. If you see a total eclipse of the Sun you are in the umbra. You are also seeing all of the sunrises and sunsets on the Earth in the red ring around the Earth caused by the Earth's atmosphere (which also causes the Blood Moon). On the other hand, if the Earth blocks only a portion of the Sun you are seeing a partial total solar eclipse and you are in the penumbra of Earth's shadow.
Maybe the supermassive Black hole wasn’t ejected, maybe it left the galaxy because it needed space 😊
Dr Becky, you're like the new version of Sky at Night (I loved that show when I was a kid), because you've got another level of passion on top of Patrick Moore's restraint. I love watching science communications even though I don't have the mind to be able to fully focus on it, so I admire people who are so passionate about the things that affect us all. I'll get back to designing interfaces that enable the rest of us to use the discoveries of science.
Makes you wonder how many stellar mass black holes are hurtling through intergalactic space and how frequently they enter the milky way.
Makes you wonder, I prefer to focus on more terrestial matters.😝
Good choice for the sponsorship. Actually looks useful, unlike the rest of the scams and junk youtube pushes.
Thank you for another informative and interesting look into the universe. I'm currently studying 1st year Astronomy and I appreciate how you're tying in what you're presenting with what I'm learning ie electrons moving between states and ejecting photons. It's great to see real life examples of classroom presentations.
When a random event like this occurs, how do instruments, such as Hubble and JWST, get assigned to have a look at it? Since their time is scheduled in advance, who decides to change the schedule? How is it even requested?
How is it commanded? You can’t just say point it there….or can you? Are the command put through a simulator first? How’s the commutation done? We need to know
Don't worry about UV coming through your hotel window. Ordinary float glass (a.k.a. green glass) is very good at blocking UV. At 300nm, you can expect 1/8th inch glass to block around 99.9% of light. It will still block 99% down to 260nm. (And if you're wondering, I did just measure it on my photospectrometer.)
Great to know, I am a victim of skin cancer so information like this is well handy. I did have to look up spectrometer, but I am guessing I would not be the only one.
@@martynspooner5822 nope. You're the only one.
UV-C dangerous wavelength is 260nm
only problem is if that isn't glass but a glass lookalike like perspex (PMMA)
@@JamesJordanson I don't know the regulations where she is at, so take this with a grain of salt, but I suspect it is laminated glass, meaning a minimum of 1/4 inch total glass plus the polymer sandwiched between the glass plates. However, it is possible PMMA satisfies local regulations, so it is possible that the window isn't glass as I assumed. Even if the window is PMMA or some other polymer, I would expect it to have UV inhibitors in the polymer, if not to protect the polymer itself (I know PMMA is better than vinyl, but I don't remember if it is completely immune to UV damage), then to protect what is behind the window.
Regardless, it is a fair point you made regarding my assumption that the window was glass.
If the scenario is indeed that two black holes orbiting on their way to merge ejected a third one coming in, it's a rather funny situation. Like, EXCUSE US, we are trying to MERGE over here! Screw off!
the crazy part is, that black hole was still only traveling 1.19% the speed of light, which don't get me wrong, very fast. but for such a dramatic event it really puts in perspective the difference orders of magnitude present
Great video as always, but a slight misspeak . You refer to gamma rays as having the "highest wavelength" (around 12:37) but I think you mean highest frequency (i.e. shortest wavelength).
In a galaxy far, far away
Something strange happened one day
A black hole that once sat at its core
Was suddenly kicked out, leaving everyone in awe
The galaxy was in a state of confusion
As they watched the black hole's ejection
It was a rare and wondrous sight
A cosmic event that filled them with delight
The black hole spun and twirled away
Into the vastness of space it did stray
Leaving behind a galaxy in wonder
A new beginning, a cosmic thunder
The stars shone brighter than ever before
And the planets danced in a cosmic uproar
The black hole's absence brought a new light
To a galaxy that was once cloaked in night
So let us gaze upon the stars tonight
And marvel at the beauty of this sight
For even in the depths of space
There's always something new to embrace.
Chat gpt 😂
Wonderful!
fast moving rogue super massive black holes could be slightly problematic. granted at only 0.5% of c you'd see it coming from quite a distance. A galaxy weight black hole could make a mess of things.
If it's moving that quickly, I don't think it'd stick around long enough to cause any large-scale gravitational distortion. Probably just capture or eject a few stars along its path and maybe throw out some intense radiation from the accretion.
@@BenAlternate-zf9nr 0.005c would be 900 years from alpha centauri to here which is a considerable amount of time for a multibillion sun mass black hole to mess things up. I don't think you quite appreciate the scope of how antisocial such a thing is :)
Excellent video Dr. Becky! This week's space news is very interesting. I loved the references to 1997's Titanic when you were talking about Uranus' year and your reference to Taylor Swift's Anti Hero when you were discussing the B.O.A.T. GRB!
Not only could I listen to her all day, but she explains things in a way that a layman can understand and comprehend. I could also stare at those beautiful eyes and gorgeous hair all day.❤
that’s just what I need right now. I was thinking earlier this evening that you might post a night sky news video tonight. And I just looked at my phone and I got a notification. Im so excited. I studied the entire day for my final exam. My head needs some free time haha. (a random German says thank you;))
Good luck with your final exam! You’ve got this 💪
@@DrBecky thanks!!!☺️❤️
Would one eventually develop from enough stars turning into black holes? Would the ejected super massive black holes find new homes in another galaxy? If they do and say the black hole attaches itself to an arm of a spiral galaxy, what effect would it have on the arm?
Usually matter is attracted to the core of a BH and a simple explanation, all the neutrinos would be consolidated into one giant 'ball'. The rest of the turbulent dynamic is fantastical to contemplate 😇
Nice presentation - loved every minute of it! Such an exciting age of discovery, thank you for being our guide!
12:30 "Gamma rays, the most energetic form of light with the highest wavelength are given off."
ITYM "highest frequency"
Thanks Dr. Becky, glad you were able to make this episode.
Hi Becky :) Can I give you a hint? Please don't show your viewers how they should feel by portraiing it on the thumbnail.. 😅
Becky, you manage to bring the perfect mix every time IMHO: Clearly sensible utter enthusiasm for the matter, serious knowledge, tons of work put into it, a gift for transporting it to the public in a very enchanting way, humor - you name it. Thank you for all of this and much more. Be safe, keep going, live long and prosper.

I wonder if said galaxy has a massive black hole in the middle of it as many do. Here is why I wonder that.
Eainsteins Time dilation is the slowing of time as perceived by one observer compared with another, depending on their relative motion or positions in a gravitational field. To a distant observer, clocks near a black hole would appear to tick more slowly than those farther away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.
(is the polarity true as well when escaping a black hole? hmm. Curious.)
Why does this matter? If one could orbit a black hole time would move slower for them (it is a time machine) in this sense.
Imagine if that "streak" is a space craft! that was leaving such a time traveling journey!!!!! Might it look something like this? 20:20
Also White holes are theoretical Cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole nothing can enter a white hole. Truth be told white halls. Could this be a whitehole/hall?! Like the Chandra xray images. Very interesting!
Because in that case. Something Escaped A Black Hole at almost the Speed of Light and NASA Recorded It.
Captured at the Chandra X-ray Observatory Center in collaboration with the Harvard-Smithsonian Center for Astrophysics, a system with a black hole and companion star about 10,000 light years from Earth was caught by astronomers. They have captured a stellar-mass black hole hurling hot material into space at close to the speed of light using four Chandra observations in 2018 and 2019.
Upon hearing that a Black Hole is spewing out material instead of sucking it all up, one might stand in a puddle of confusion. It begs one to ponder that perhaps they’ve located a white hole instead of a black hole. White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, (we think lol)
nothing then can enter a white hole. (we think lol)
Truth be told, white holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. More recently, however, some theorists have been surmising that these twin vortices of spacetime may be two sides of the same coin.
To get a better understanding, let’s tune-in to theoretical physicist at the Centre de Physique Théorique in France, Carlo Rovelli. He asked audiences to imagine floating in space in a high-tech spacecraft observing space. From afar, a white hole looks exactly like a black hole. It has mass. It might spin. A ring of dust and gas could gather around the event horizon, and just as usual, the bubble boundary of the black hole separates the object from the rest of the universe. But if the space travelers kept observing, they’d eventually realize the supposed black hole give a hearty belch. Carlo Rovelli says, "It's only in the moment when things come out that you can say, 'ah, this is a white hole.'"
So, when the Chandra X-ray Observatory Center framed graphic optical and infrared images of the space area called Maxi J1820+070, and data revealed that two jets pointed in opposite directions, launched just outside the event horizon of a black hole, shock spread across the field. Here are the details of this shocking find. Waiting for us. Here’s the vital notes of the eternal mysteries of space. Here’s the best place to learn about the infinites of space. This is an opportunity for us. We can take JWST and expand upon their research thanks to innovations in recent years Our hopes are high and our faith is placed in JWST's capable proverbial hands. We wait with baited breath for News on its adventure!
I'm not sure why, but my first thought was that some hyper-advanced civilization was lobbing this black hole at an enemy galaxy! Anyway, great video Dr. Becky, love your work!
Of course this is the answer. No reasonable person could argue against a relativistic kinetic black hole kill missile. They'll never see it coming. 😉
Oh my god! What did the other civilization do to make them THAT angry?
"use the force Luke"
Luke messes up and ejects the black hole away from the galaxy
"Luke maybe you shouldn't use the force anymore"
According to most space science channels ive watched, this image is more likely to be a super flat galaxy than an ejected black hole
I'm from West Java and today a partial solar eclipse was happened and I'm mad because it's been cloudy all day 😩
Boooo clouds!
😢
Questions, can JWST can see tru the galaxy and see the other side of it???
And it will have new observations of previous black holes to get new data on them???
With the runaway black hole, it’s kind of like Beyblade on the most epic scale imaginable! 😮
😅😅😅😅
I like the way you think.
It’s just a little scary to think, there could be a super massive black hole m, speeding through the universe, heading towards our solar system. Unlikely, I know, but I guess now proven possible by this observed event. 😮
At the end when you say that according to our current understanding, you can remove the black hole in the milky way.
I did thought for a moment that you'd say "but please don't test that until we've observed more cases" 😂
If that galaxy has ejected all it's SMBHs, does that mean it'll eventually fall apart (due to insufficient gravitational pull)?
13:06 Now I hate to be that guy. But I can’t take this anymore. Don’t GRB’s come from Hypernovea, not Supernovea? Unless that’s outdated information. I’m very confused. As that’s what I’ve heard my whole life. I learned it from a space documentary series called “How The Universe Works”. Which is a great show, I definitely recommend it! But, yeah. I’m just confused. Also, that show also said that, only Supernovae made Neutron Stars, while only Hypernovae made Black Holes.
The idea that a gamma ray burst lasting milliseconds can put out more energy than the sun over 6+ billion yrs is just crazy and mind blowing... It's just WOW, huh, OMG, WOW....
Thank you for coming to TO and on a nice Week. I hope every moment goes great and you have a safe trip back home. I love your knowlege and also the relaxing style that you tell us of the astro news.
I am slowly getting your book read. I am on ch.4 why black holes are black.
Wow, cool af, I love Uranus and supermassive black holes. My science school teacher gave me detention for admitting this. I wish I could show her this video to explain these are things to love.
Btw, your passion for science is amazing.
JWST continues to amaze.
"False Colo(u)r" is a terrible name.
"Color Shifted" - can we use that?

Q: How do you find the largest black hole in the universe?
A: How do you NOT find the biggest black hole in the universe?
My favorite astronomy news source. ❤️🔥
Whats Chandra up too? We dont hear much about the XRays. You know that B left me before we even got together. And with my Best Friend, whos not my best friend anymore. I get no respect, I tell ya
You're going to Huntsville? It would be the coolest collab to see you and SmarterEveryDay connect on anything/everything about space!
The ejected black hole got me thinking about something. I'm aware a number of galaxies have been found recently with no dark matter. Do you happen to know if they lack a super massive black hole at their core?
I bet growing mushrooms on the moon could at least be easier with greenhouses without any wind factor, and less frequent replacements in the shade, while different kinds of plants can be more self sufficient in the sun, like prickly pear cacti, and beans can be good at putting nitrogen into the soil, with ph of lunar soil being high for many plants typically, and without oxygen on the moon? I'm sure liking this alkaline water at the water store with calcium, magnesium, and other minerals though.
Hi Becky you got to be the most exciting girl that I had ever found in RUclips. Your are the coolest one and I like all your videos. They are all so interesting and informative. Keep on posting new videos.
Becky i look on RUclips all the time for content like this i have for years and finally i find you in 2023 my brain has ignited its theoretical part again, thank you so much,.
❤
I have a theory about the afterglow.... could this object be old enough to have emitted the burst whilst expansion of the universe was still more rapid than it slowed to? i.e. surf the expansion wave, not dissipate according to usual rules of radial distance from source etc....?
Lol😅 afterglow
In any movie set in Paris, it is mandatory to have the Eiffel Tower visible in the background. In Toronto, the same thing for the CN Tower 😊
Did not enjoy reading The Three Body Problem but it was a horrifying glimpse at what life might look like clinging on by fingernails in an unstable system.
Welcome to Canada! What a great video, and the real G.O.A.T. is Shania Twain :)
Cheers from the Pacific West Coast of Canada.
I liked that observation of the second black hole being ejected in the opposite direction, But I was wondering if there is a name for the stability of pairs of bodies ("rule of two" - Star Wars reference)?
Also, is there a distinction between the use of the term Collaborators and "et al" in Astronomy, or are they synomous?
GRBs are basically intergalactic Hadoukens and we're all waiting on Ryu and Ken's training so we can fire some back.
Dr. Becky I might be blind but I think you forgot to add the link to the remarkable in the description.
I usually ignore or skip past ads but that looked pretty neat. I was going to check how much they cost but... I also don't see a link.
Thanks for the heads up! Added now 👍
@@DrBecky Thanks! 🙏I've been thinking about getting one for a while and your video finally convinced me. I just wanted to make sure to use your affiliate link to support your endeavors, because I truly enjoy the videos you put out!!
Thanks Dr Smethurst. Amazing stuff. Really enjoying your book also. 👍
I think Id like to stay away from Gamma Ray Bursts. What kinda Sunscreen do ya need for that?
I find this funny because galaxies don't tolerate things in their centers at all... galaxies are enormous rail-guns
Wow these ejected black holes are so cool!! The turbulence of them plowing through the intragallactic medium is causing star formation even! Reminds me of Merrifield talking about galactic spiral arms ramming gas together to cause star formation. Loved having Becky talk about this but would also love to hear what Mike has to say!
It's so enjoyable watching someone so passionate.
Hard to believe a 20 million solar mass BH was thrown like a softball....
Slow down, my heads still not got over Jupiter's red spot not being dust.
The NH3 & C2H2 experiment was fascinating
The BOAT GRB is a fascinating discovery. It's amazing how much we can learn about the universe from studying gamma-ray bursts.
It should be called the GOAT GRB.
They need so much more datur, though.
ive sused it gamma ray burts are space ships (light/warp/paradox prevention) kinda of sonic boom but with faster then light travel.
so like if you made a loud sound and then travelled faster then sound in the direction of the sound wave
the sonic boom would eliminate the wave as it travelled so you wouldnt be able to hear it.
the same type of thing happens with light but instead of a sonic boom you get a gamma ray burst.
so you cant see where your going to be , or your self after you leave.
big guess but makes sense to me
thx dr. becky for allowing us to keep up with the recent news!
I think the penumbra is not because of earth's atmosphere. It's because of the sun not beeing a point light source. (Or is it a combination of this and the atmosphere?)
You are correct. The fuzzy shadow comes from the diameter of the Sun. The red coloration comes from Earth's atmosphere.
20:19 Is it just my impression or is there a big ring/bubble around the big oval object on the bottom?
I'm curious what you think about the new image of the M87 black hole. Some online comments were criticizing it, but it seemed reliable to me, which is why I'm curious for expert opinions.
24:05 So the poor galaxy merger is left with no massive blackhole in its center?
I enjoyed watching the sun come for you as you were going along. Very rude sun getting in your shot
Me being on a mild exo-weather jag right now, kinda wondering if Uranus' "snow cap" might actually approach solidity. Obviously, not remotely close to a full ice, but is there even a remote possibility of something like a loose aerogel mass accumulating at that level? Know any people or sites to point an obvious noob like myself at?
It is masses of microbes that grow during sunlight and then go dormant in winter.
Sorry if this has already been mentioned but the "previous video on the effect of removing the Milky Wy’s supermassive black hole - " has no link in the description. Awesome video though! Its amazing that the ejected black holes spawned star formation in their wake. Would these regions be considered new dwarf galaxies or part of the original? Space is awe inspiring.
Yes - no link. Where can I find that video, please?
