You should try to contact Yvette Cendes (first author on the black hole burp paper) to come on for a video; she's fairly prominent on social media and I'm sure she'd be up for an interview or something!
Thanks for making the dance of the stars understandable, (nearly) for us laymen. Those images w ere simply stunning. Thanks for sharing your knowledge and passion and giving black holes the respect they deserve, I think.
I 'read' your book on Audible recently. Very well written and wonderful narration by you. Recommend it to everyone. My favorite line was Black Hole is not black and it's not a hole. Thank you for your great work.
I just downloaded the full res pillars of creation image. That thing is huge. The slow banded display of it as it downloaded reminded me of what it was like to download ANY image from the internet (or pre-internet BBS systems) way back in the day. So it was kinda fun for that reason alone.
@@EnglishMike When the pandemic started and I had to work from home, I needed to be able to download and upload to the server for work, so I got gig-gig internet That's literally 125Mbps upload and download. By the time windows opens a window to save a gigabyte file, it's already downloaded, just gotta hit save.
@@kindlin Yeah, and it's funny that while I sometimes chafe at the fact my upload speed is limited to 12Mbps, that's still double what my download speed was just a decade or so ago!
Unrelated to all of this I just saw the blinking planetary nebula in cygnus yesterday, 4 months since I bought my first scope and I love space! Thank you for all of the inspiration Becky, your passion is contagious. I cant wait for Orion to move into early evening skies so I can observe all of the wonderful nebulae around it.
I'm an amateur physics nerd.. And I'll tell you why I watch your channel. Your enthusiasm and love for what you do. Even if you scroll thru the thumbnails for your vids.. Its always all over your face! That enthusiasm coupled with the way you explain concepts, which arent easy, means that me, who scraped a b in gcse physics, can feel slightly clever! That and thanks cos I've just seen some cool meteors cos I've looked out of my windows looking for the planets.. So thankyou!
Dr Becky, your book is so informative and a great read. You are doing an amazing job and helping us learn and understand what’s going on up above. Keep up the great work
This is an awesome video as always! Hats off to your Scientific spirit and your amazing ability to explain complex astronomical science to lay people that even first time viewers are also enlightened! Can't thank you enough for what you do...we are so fortunate to watch you!
8:08 don't mix it up with the well known filter wheel though. That is used only for the imaging part. This is 1 of 2 wheels used only for this mode. They have on one end dichroics that split the light into 4 different sections of the wavelength called channels (1-4) and send those along their seperate paths and on the other end there are gratings which split up the light into the proper spectra. Each of these 4 channels (frequencybands) are further divided into 3 subbands each (short, medium, long). Now the spectra is made for each channel at the same time but only for one (for each the same) subband. (All short, all medium or all long). The wheels in question are there to select the subband.
The day the new image of the Pillars of Creation was released was my mom's birthday, and she would have turned 62 years old. That makes this one really special. 💕
Thanks for the heads up about the eclipse for Melbourne, Australia on November 8! Also, to those who haven't yet, read Dr. Becky's latest book - it was so easy to read and understand and damn black holes are wild! Well done, Dr Becky!
I love the JWST image of the Pillars of Creation! The timing of the release worked out well for me as I was looking for images of stars for a music video I was working on (which comes out on Saturday BTW :) )
Man you have great graphics! I love the specific explanation you're are able to provide that is not normally available to the general public for consumption!
I LOVED your book!!! I was dying to read it because I'm so intrigued by the idea of a primordial black hole in the solar system, and that chapter and the whole book did not disappoint!!!
It seems that discoveries in most aspects of science are coming faster than when I was a child in the 70's. So many awesome things coming and have arrived.
Funny that you start the video with a mention of the new book being out in the U.S. now. I literally got an email from Amazon five minutes before watching this, alerting me to the fact that my pre-order of the book has been delayed yet again, and that I'll get another email at some point in the future when it finally does ship. I'm not complaining. This is a great problem to have. It means that tons of people have jumped all over your book and are eager to get their learn on, and that makes me very happy. Yay for people wanting to learn!
Thank you so much for including the link to the JWST image of The Pillars of Creation. Spectular and I'm happy to have it so that I may share it and look at it more closely. Really enjoyed the entire video and look forward to all those you post.
Man, I love your passion for your profession. It makes watching your videos so much more interesting instead of like a teacher at school with the blah blah blah.
CBC actually had Yvette Cendes on the radio program Quirks and Quarks today taking about this TDE's delayed outflow - thank you for covering it with the visuals!
I am so happy to see your video. It answers so many questions especially about the brightest Gamma Ray Burst. I listened to your book on Audible. I appreciated that you did the narration, you did a brilliant job! I really enjoyed it. I will need to listen to it again as I still want to understand the concept of accretion disks around a black hole. I have to agree. I wish we had chosen a different name for black holes!!
Spent the evening last night with our 5” guided scope looking at the moon, Jupiter, and Saturn. It was too early to see Mars. Saturn is so spectacular, even though Jupiter is so much larger and brighter. We need to get out of the city to really enjoy the dark sky. Thanks for putting out this information!
Our creator is awesome, spectacular n of course powerful to have created the heavens n the 🌎 earth n everything we need to live on earth without flying off as we orbit the sun. The study of creation including us can draw us even closer to him. I give him all the credit to have given us what we need to survive 👍 Thanks for sharing 😊
Probably a daft question, but could the delay have been caused by time dilation due to the intense gravity? So for the matter that burped out it was only a few minutes/hours/days, but for us it was 2 years?
That is my initial hypothesis too, we are probably wrong but it sounds logical with my extremely limited knowledge of physics, but I thought it was due to speed of the mass swirling. I wonder how fast it spins in the disc before it gets too dense (if the theory is right).
In your segment about the lunar eclipse, I got very excited because I live very near Seattle and you just happened to use Seattle as your example. I then got annoyed because the maximum is way later than I plan to stay awake for. Love the video anyway! :)
RE: delayed burp from black hole. Is time dialation or gravity slowing the particles exit velocity a posible explanation for the delay? if not, why not?
Tonight, I saw Orion and also thought "winter is coming", and also saw a bright red dot "above" the head of Orion. I thought "Huh, I didn't remember Aldebaran being this bright" It was Mars. Thank you Dr. Becky for the reminder!! Much love :D
Great stuff Dr Becky, the Pillars of Creation pictures are beyond stunning, so many questions about how Stars are made inside this huge Galactic factory and how does it know what to do to create Stars?
I think the quickie version is this: the pillars are part of a giant molecular cloud (GMC). Within GMCs-cold clouds of gas & dust-the density is not uniform. The denser clumps of matter have a gravitational potential (compared to the sparser regions) which eventually begin to pull gas & dust to their center points of mass. Long story short, a protostar eventually forms, and pulls the remaining, available, nearby gas & dust to itself that it can, effectively clearing out a little region in the GMC. *IF* the protostar has accreted/accumulated enough mass (to “generate” enough gravity, to squeeze the core of the protostar enough, to make the core HOT and dense enough), the nuclear fusion of hydrogen into helium can finally occur in the core, and the conversion of mass into energy (E = MC2) results in an outward “pushing” force called “gas pressure.” Once an *equilibrium* - AKA “hydrostatic equilibrium” - is achieved between the inward crushing force of gravity (due to mass) and the outward pushing force of gas pressure from the core (due to the nuclear fusion occurring within), the stellar object is now officially a main sequence STAR.
Whenever you say keep looking up, it feels like you are channeling Jack Horkheimer. He was on late after Dr Who on my PBS channel in Sacramento back in the '90s.
The "like" button has disappeared, so here I'm telling you; Thank's Dr. Becky, I really really liked this and all your shows and of course, You Becky! X
Hah. That jobs questionnaire is more common than I realised. It suggested I become a tree surgeon or forensic scientist. The 80000 hours suggestion is handy. Thanks.
Thank you Dr Becky, I love to know about the universe but there’s so much going on, your news are very helpful, easy to understand and exciting. Greetings!
Love your channel - just one small thing I've noticed over time - since you've been using LED lighting the picture is now regularly very pink. Some creators use higher quality lighting - there are various LED lamps that do not have this characteristic. But of course if you like the pink look - that's entirely fine! The main thing is your content and delivery is excellent - thank you
Are black hole accretion disc's typically in a particular plane? I would expect them to be aligned with the equator (for want of a better term) of the black hole, but is the axis of black holes in a particular plane or are they randomly pointed all over the place?
I have the audible version of your book A Brief History of Black holes. Is there any way I can get an autographed hard copy here in the US ? Thank you for all the great education that you provide Us.
I am having trouble finding where you want me to look at times. Is there any pointing tech you could use to pinpoint what you want us to focus on? Like wispy blue gas, took me a while with that one.
Question for Becky ,. Does an accretion disc , get so dense that the material can actually trigger fusion within the accretion disc , which would indicate that not all of the light is from heat and friction
Hello dr Becky, I’ve already read your new book in digital copy, so you know if a French version will be available in Canada when it comes out in nov 1st. I’d like to get it for my daughter, she aims to be an astrophysicist (she’s 13).
When applying false color, is there a standard translation for what wavelength becomes what color, or is their relative length to each other the only thing that matters?
what if a combination of material and gasses around the black hole became explosive in a certain concentration of matter cluttering the space around the black hole and then different materials and gasses or different ammounts became later exlosive or anyway naturaly colided with each other in a different concentration later? (2.5 years)? Do we know so specificaly at which point the ring is "burping"out matter?
Love your explanations: they are explained in terms that are easy to grasp (or at least I assume easier than the reality). Why are the colours/heat depicted this way round? We are far more used to black/blue being cold and graduating up to yellow/white.
While it's only one of 17 modes, my layman's understanding is that the MIRI medium resolution spectroscopy mode is the highest- resolution spectroscopy available in the unique mid-infrared wavelengths that JWST is able to use. My interpretation is that this makes it a fairly important mode; spectroscopy allows extracting critical information from light sources that regular imaging otherwise can't, and we have very few instruments capable of imaging well in the mid-infrared and none with the spatial or spectral resolution of JWST and MIRI specifically. I certainly hope they're able to sort the problem out and continue imaging in this mode!
Hi Dr. Becky. Something I was always curious but not sure if you ever went into in a past video: in images like the Pillars of Creation one (more the NIRCam one), do we know, for example, which stars are in front or behind of the object we're looking? I know we could pinpoint if we looked star by star, did a redshift measurement etc but in a general way, is there a way of telling it? Of course comparing Miri/NIRCam we can kinda make out which is which, but even in MIRI there are some that look like they're in front, or maybe right behind the dust, etc
What would the catastrophic death radius be for that gamma ray burst? If it’s that far away and it effects Earth, i assume it would be worrying if one happens substantially closer?
would it even look like that anymore because of the redshift? would the structure be different is there any way we could ever get a real-time image, or would we need a quantum entagled camera (quantum bits adjusted to the same across the galaxy to generate an image that is real-time.)
Why do the planets appear (even when seen in person, not just a photo) to be in an arc? Since we're on the same plane, I would expect them to appear in a line. (Any points on a plane viewed from another point on a plane describe a line.) Or is this just an optical illusion due to the angle to the horizon, and if I held out a long ruler, they'd actually line up? -- I don't think so, because I tried something like this.
The _GRB_ {Gama Ray Burst} Dr Becky mentions in this video occurred *2.4 BILLION YEARS AGO,* yet it STILL affected some radio transmissions HERE ON EARTH. The amount of POWER behind that burst must must have been truly staggering....
hi, Dr B! very interesting items and spectacular photos. it's amazing what can be determined from visual clues, such as the wolf-rayet star. i know there's more to it than visual info but, the pics lead astronomers to study the phenomena, i guess. also, i ordered your book on black holes when you 1st announced it. i know it's available in the US Nov 1st but, when can i expect it to be shipped? will i be notified? these questions were probably answered at the time but, my memory isn't so good, these days. thank you, for any info you can give me. see you next time!
Dr Becky, some time in your life you need to come here to Alaska during the winter time and watch the sky, it is spectacular. And if you want to really see everything, go to Barrow which has 52 days where the sun never rises. A question about the gamma ray burst. With such a powerful burst, if there was life in that galaxy could it have been wiped out??
Saturday the 29th here in the Netherlands, it is the Night of the Night, the evening when us amateur astronomers do things with and for the general public, and many observatories open up for the general public :) so it will probably be clouded :(
Why is the accretion zone just a disc, and not a sphere? Why can't matter orbit in just any direction, for example if it arrives with momentum at 90 degrees to the disc?
Dear Dr B.! Tried to find you on Patreon, but you don't seem to be there. Anyway, I have a question - probably very naive, but no idea - but obvs new to me. OK, so allegedly 85% of the known universe is made of 'dark matter'. And allegedly that stuff only interacts gravitationally. So, why has a huge amount of that stuff not since disappeared into 'dark matter black holes'? Surely, if it 'interacts gravitationally' then it should self-attract, no? Probably an obvious bit I've missed, but that's how we learn, I guess! Thanks, K

Something I was always curious but not sure if you ever went into in a past video: in images like the Pillars of Creation one (more the NIRCam one), do we know, for example, which stars are in front or behind of the object we're looking? I know we could pinpoint if we looked star by star, did a redshift measurement etc but in a general way, is there a way of telling it? Of course comparing Miri/NIRCam we can kinda make out which is which, but even in MIRI there are some that look like they're in front, or maybe right behind the dust, etc
What would the catastrophic death radius be for that gamma ray burst? If it’s that far away and it effects Earth, i assume it would be worrying if one happens substantially closer?
@Dr.Becky. There are so many stars in the pillars of creation, how close are those stars to each other?
would it even look like that anymore because of the redshift? would the structure be different is there any way we could ever get a real-time image, or would we need a quantum entagled camera (quantum bits adjusted to the same across the galaxy to generate an image that is real-time.)
Why do the planets appear (even when seen in person, not just a photo) to be in an arc? Since we're on the same plane, I would expect them to appear in a line. (Any points on a plane viewed from another point on a plane describe a line.) Or is this just an optical illusion due to the angle to the horizon, and if I held out a long ruler, they'd actually line up? -- I don't think so, because I tried something like this.
I'm buying your black holes book as a Birthday present to myself!!!
becky what is that black hole looking object on the pilliars photo theres a cluster of 4 bigger stars on the lower of the 3 pillars ?
The Pillars of Creation image is simply stunning. Becky, what is the extra bright star in the upper centre of the image?
The _GRB_ {Gama Ray Burst} Dr Becky mentions in this video occurred *2.4 BILLION YEARS AGO,* yet it STILL affected some radio transmissions HERE ON EARTH.
The amount of POWER behind that burst must must have been truly staggering....
hi, Dr B! very interesting items and spectacular photos. it's amazing what can be determined from visual clues, such as the wolf-rayet star. i know there's more to it than visual info but, the pics lead astronomers to study the phenomena, i guess.
also, i ordered your book on black holes when you 1st announced it. i know it's available in the US Nov 1st but, when can i expect it to be shipped? will i be notified? these questions were probably answered at the time but, my memory isn't so good, these days. thank you, for any info you can give me. see you next time!
Dr Becky, some time in your life you need to come here to Alaska during the winter time and watch the sky, it is spectacular. And if you want to really see everything, go to Barrow which has 52 days where the sun never rises. A question about the gamma ray burst. With such a powerful burst, if there was life in that galaxy could it have been wiped out??
Saturday the 29th here in the Netherlands, it is the Night of the Night, the evening when us amateur astronomers do things with and for the general public, and many observatories open up for the general public :) so it will probably be clouded :(
Why is the accretion zone just a disc, and not a sphere? Why can't matter orbit in just any direction, for example if it arrives with momentum at 90 degrees to the disc?
Dear Dr B.!
Tried to find you on Patreon, but you don't seem to be there.
Anyway, I have a question - probably very naive, but no idea - but obvs new to me.
OK, so allegedly 85% of the known universe is made of 'dark matter'. And allegedly that stuff only interacts gravitationally. So, why has a huge amount of that stuff not since disappeared into 'dark matter black holes'? Surely, if it 'interacts gravitationally' then it should self-attract, no?
Probably an obvious bit I've missed, but that's how we learn, I guess!
Thanks,
K
