She is so clear, such a quiet charachter. My favourite scientist/teacher.
character is how it spelled

I could listen to this lady all day long, beautiful.
I always love the deep sky series, but this one in particular was amazing! I liked being taught about the science, but also getting a peek into how the research itself was performed!!
Higgins2001 thanks
what humbles me is how much time, effort, dedication and care goes into even the smallest bit of science that we get to hear about. Ten yeas of ones life studying this single image, its every nooks and carnies, every distortion, smudge and blob. That, my friends, is what it takes to do science.
"Carnies" are what it takes to do carnivals.
It's sad really
Your videos are always interesting and I don't care that you only upload now and then. As long as they keep coming I will be happy.
BirdSpy Aus thanks for watching - I really enjoyed making this one because it tells us so much about a real science research project
DeepSkyVideos thank you for the great work =)
More from Mrs Gray! I could sit here and listen for hours.
Always love to see one of these featuring Dr. Gray; she so clearly loves what she does, and her enthusiasm causes the viewer to get pulled in a little further than would have been the case otherwise.
Thank you, Brady and Meghan.
Dr Meghan Gray is so awesome,really love her videos.That's just one patch of sky with so many galaxies and stars.....mind blowing stuff ! I'm so glad there are people like her dedicating their lives to solving just a piece of the overall puzzle of the universe.
Just amazing !
When she's talking about the one galaxy cluster behind another, it's so weird to realise that the more distant cluster as seen in the photograph is possibly thousands of years further back in the time than the cluster right in front of it.
One picture of two things, and the picture is seeing one of them thousands of years further in the past than the other. It makes me feel weird.
Also the way she says "flocculent" is awesome.
This picture ilustrates very good the lightcone concept. All the light we see is NOW for us, but for those on the other end our PAST is their NOW.
It'll be a heck of a lot more than mere thousands of light years further back, I can tell you that much. The Andromeda Galaxy is over 2.5 _million_ light years away, and that our closest neighbour!
marzcorp
Yeah, I guess I didn't really think that part through. Even though I know The Milky Way is ~100,000 light years in diameter.
Thanks for the correction.
Well, down at the Creation Museum they don't believe the light we are seeing from those galaxies is really billions of years old. They go with the mere thousands of years as in your first estimate.
"'Space,' it says, 'is big, really big. You just won't believe how vastly, hugely, mind-mindbogglingly big it is...'"
you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
*"DON'T PANIC!"*

@@Allan_aka_RocKITEman And don't forget your towel.
@@spikespa5208 >>> 😊
Yet some of us do some come from the black hole didn't you know 🤭🤫
It just makes me happy to know there are people in the world studying this stuff. Keep up the great videos!!
Am aware it maybe should be "tens OF thousands OF" but that is not quite such a snappy title in English!
actually it means _"ten thousand of"_ the german word for _"tens of thousands"_ would be _"zehntausende"_
in case you refere to the title of the picture :x
Stephan Bischoff That's actually what it says on the poster. "Zehntausende" means just like he said "tens of thousands of". "ten thousand of" means "Zehntausend".
Similar "Hunderte" and "Hundert" means "hundreds of" and "hundred".
pcfreak1992 thats true :D
And in dutch it would be "tienduizenden"

One of the most outstanding series of videos I've ever watched regarding astronomy & astophysics...whenever I point my telescope & camera combo to do some electronic assisted astronomy, I first search on DeepSkyVideos library to see if anything relative to my target is uploaded...trully gives a super boost to my observing sessions! Love u all guys... we need MORE of such GREAT videos!!!
I love listening to this lady speak. Knowledgeable and seemingly extremely light-hearted, I surmise I would enjoy her as my professor.
Just wanted to put that out there :-)
yeah i felt that too. calmness.
It is always such a distinct pleasure to watch Dr. Gray narrate one of these videos. Her way of explaining what she is viewing is absolutely clear and distinct. Thanks you.
Fantastic. One of my favorite videos so far.
I love listen to Meghan, she explains so clearly. Great video. Why is this recommended 6 years after it was created?
Just discovered this series after watching Sixty Symbols and Periodic Videos for years. Love it! I salute the dedication of scientists like Dr. Gray, but I'm a bit envious of them having jobs that are so interesting. Beats staring at the same monthly reports and getting excited about how many office supplies get ordered every month! Bravo to Brady and Meghan!
I love to hear Dr. Gray explain anything
What a wealth of phenomena in such a limited patch of sky! Thanks Mrs Gray and thanks Brady!

I’m in highschool and in my sophomore year my teacher showed us that picture and it’s so cool to hear it explained !
Keep learning!
Wonderfully articulate. One thing to know, another to communicate.
I would love to have a job like this. The data they use is so beautiful and the science behind it is so interesting.
You could join the Galaxy Zoo citizen science project and be a volunteer ... somewhat like this.
Daniel Mocsny Yeah? I'll check it out!
Great video. She speaks with a soothing authority on the subject.
this is probably my favorite Deep Sky video you have ever published Brady!!!
AM i able to download an HD version of this somewhere? would love to print this off and hang it, just knowing i have now seen some of those smudges up close and what wonders they truly hold!

Pull up. N A S A
Very nice video, I like the way she explained the photograph and showed the corresponding Hubble images. Must watch for middle / high school kids who are interested in science.
saw the video now but very nice way of explaining things . like a seasoned teacher :)
It sort of melts my brain to think about those distant red galaxies. Just the distance and the time and everything. There's just something about them that boggles the mind.
Brady, i am in love with your work. Great journalism, impressive topics in every video. I admire this form of research. you let people inform us, who actually know what theyre talking about, instead of distorting every story so far that it can hardly be called science anymore. Subscribed to all of your channels i found so far!
Holy cow, now that is something worth displaying on a wall, beautiful.
I know of the Deep Sky where a long exposure of the Hubble of a patch of sky where supposedly, little was in, but found many galaxies.
I love Meghan's videos, this was no exception. Great stuff.
Thank you for sharing such a beautiful image.
I'm sure this has been noted before, but as a native and more importantly pedantic German I can't let this go by completely quitely: Actually it says "Zehntausende Galaxien ..." not "Zehntausend Galaxien ...". The "e" at the end of "zehntausend" is an undeterminate plural indicator which makes this more like "tenthousands of galaxies ...".
I just thought, I'd mention this, because the number in the video title seems so terribly specific, when it really shouldn't be.
Other than that, this is an awesome video. I always love these videos with Dr. Meghan Gray. She's so beautifully sincere yet passionate about this. :)
More of this woman please! I find her accent mesmerising
I truly enjoyed this video. Thank you Brady & Dr. Gray!
Brady there is also another great Hubble composite image,the 'Ultra-Deep-Field', a sky patch in Cygnus/Lyra, that's also very dense with thousands of galaxies
What an awesome episode
After graduating to an electrical engineer, I think and I'll go and follow my dreams and try to study as an astronomer. Everything about space is just so fascinating.
I feel sad for the millions of people growing up in cities the world over who have never looked up and seen a starry sky. Excellent work Brady, thank you. And Dr Gray.
Dr Meghan Gray you are one of the people that make me proud to be Canadian.
I love these images from Hubble. I have a 4.5 inch telescope and mainly observe the planets when I can get the chance and I am not sure if I would be seeing galaxies or not when I view stars.
Intelligent and beautiful.
Awesome teacher and video. The best to you Brady
Whenever I think of the other galaxies... I feel like... I mean, our galaxy is already HUGE. It would take millennia for us to travel from one point to another. But other galaxies, they are SO, SO, SO unimaginably far away. And to think we don't even know our galaxy fully. We don't even know if we have other planets like Earth in it. And these galaxies are just teasing us, beyond our reach.
It's completely amazing to me.
We don't even know the dirt under your fingernails fully. Human ignorance is abundant at every scale.
Some of those stars are in the shape of a mini Orion! Cool!
Man, I dig listening to intelligent people. I love listening to Dr. Grey who is very calm and soothing, but also Professor Merrifield who is quite frenetic and the complete opposite.
AMAZING... I wish there was a 4K picture on the internet that I could zoom in and out too see it as a whole or just individual objects (galaxies ofc). Just for the pleasure of doing it :)
Great presentation..again!
Wow. Just wow. Especially the bit with the Einstein ring. I have never seen a picture like that.
To look at galaxies as if they were grains of sand. Mind-boggling.
"Astronomers love their acronyms. The more contrived the better." This is an important part of the aesthetics of many fields of endeavor. It gives them an arcane flavour.
I was up until 5am last night, out in my garden with a DSV playlist, a printed sheet of the brightest (by magnitude) Messier objects, and my SkyWatcher 130M 5.1" reflecting telescope.. t'was a good night :)
Fascinating! Thank you so much for the upload.
Imagine how much life could be in each of those galaxies. They could be teaming with life or... could be absolutely devoid of it.
120B Galaxies and that is all we can " observe "! = The Observable Universe - Just 1 Galaxy (Milky Way) = 250 Billion ± 150 Billion Stars - Just 1 Star (Our Sun) = 7± Planets - 1 Planet (Earth) = 7± Billion People.
Red shift
Einstein rings
I miss a lot, but it's fascinating how much sense these things already make.
10:00 From what I gather, that "star-forming monster" is the result of two galaxies that formed separately and eventually were drawn or pushed together, yes? In my head, I'm imagining two semis smashing together, only instead of spewing out shrapnel, they've spewing out stars.
Is that type of event something intense and chaotic whose effects can be "felt", as it were, throughout the whole galaxy? Or, because of the relative size and time scale, could those galaxies' daily lives go on largely unchanged regardless?
puncheex2 In that analogy, though, how far-reaching would the pull of gravity be from those stars?
Ben Green Not an analogy, really, but just a scaling. Gravity does indeed reach infinitely far, but a star similar in mass to the sun would have to pass fairly close (say, somewhat closer than San Bernardino) to measurably affect our solar system. The orbit of Neptune would be about 450 meters from our sun. To invoke a collision it would have to be at least within that circle, I imagine.
The professors at the University of Nottingham are extremely inspirational. I wish I was of the age to be able to attend University there.
Love u from INDIA.
LOVE UR EFFORT.
UR APPROACH.
thank you all who did any thing for this vid.
I want to buy that poster now
Watching this, I am reminded of the words of Gargravarr from Hitch-Hikers guide to the Galaxy "...your self an invisible dot on an invisible dot, infinitely small..."
So fascinating
I like your dedication and passion. Great videoclip, I enjoyed.
Thank you for sharing 🙏
awesome video as always. It would be interesting to see a 3D projection of that image.
Absolutely fascinating!
Excellent video.
Comedy and fantasy all in one love it
Very interesting video.
I love galaxies! I would have loved to visit you and have you show me all these and many more of the galaxies in your field.
Is there a composite image of all the hubble images together? As cool as it to go through each shot individually, looking at the entire thing in one shot and zooming in and out would be amazing!
Thanks for shearing your knowledge.
Would love to see a follow up video on what was learned from this work.
Nice information. Thanks. Why does the distant point like galaxies not have a diffraction pattern as the stars do?
What's fascinating to think about is, what must our galaxy look like from a planet in one of those distant galaxies, and who's there looking at us through their telescopes?
Beautiful and fascinating.
thanks brady!
So far away and so beautiful a the same time. I only wish more people were looking outwards towards all those stars. For science!
It was probably repeatedly falling down because the glue got old and brittle..lol.
its funny how in the video sped up of the telescope following the area in the sky, the sky is moving quite a bit faster than the telescope viewpoint, so the sky here is superimposed onto the image.
Curious about two things: First, is there a reason why some parts of the sky have more large scale structure than others? Second, are the red galaxies red only because of their distance away from us (perhaps light waves begin to break up or lengthen after traveling billions of light years?) or because they are also moving away from us faster than closer galaxies?
I always wonder how they find those very interesting galaxies out of tens of thousands of galaxies, like the one with the Einstein ring
Is there a focusing ring on the Hubble or other deep sky telescope? and how is it marked, 100 light years away, 1000 light years...? or is it just set to infinity? (and beyond)
Very well presented
Not able to comprehend the size of this picture. You said its just a small square patch in the sky, about the size of ur thumb from you pov . But looking at the sheer number of galaxies, its not a small patch of galaxies? Appears to be much bigger. Consider the point you are standing as s central point of a circle. At any given time, without tilting the head, eyes can see say about 150 degrees out of 360. Tilt your head from side to side and you can see upto 270degrees, only the area begind your head is not visible. So, isnt the image you showed covering about 150 or so degrees ? Peripheral vision i mean, like an infinite cone where the tapering side end is your eye and the other side which keeps increasing is your viewing surface?
Another question Suppose u are standing at a point in earth and looking at the moon, what is behind the moon , or for that matter behind any jumbo star? It will not be even visible due to bright rays of light. Is there a possibility that another galaxy exists behind lets say sombrero galaxy,?
Oh boy!
"One of these stars is not like the others" aka Sesame Street ;)
Holy crap we are so insignificant! Amazing video...
Sadly, given the limits of our current technology, none of us alive today will ever be able to visit any of those galaxies, unless a more advanced civilization travels to our planet (from within or outside the Milky Way) & take us there.
How sad, but at least we can enjoy the scenery from light-years away.
Perhaps sadly for us, but happily for the rest of the universe. We humans are currently inflicting the sixth big mass extinction on the one planet available to us. Until we learn how to manage our home, we are not worthy to make a similar wreck of a larger chunk of space.

Well, that’s assuming we are the more destructive of all creatures in the universe, which may not be the case.
For all we know, we may be the peaceful ones that coexist better than others, despite our imperfections, given that most of us would prefer a utopian existence free of wars crime & pollution, but the hegemonic structure of our rulers lends to the sacrificing of our planet's wellbeing for them & their cohort’s personal gains.
To be fair, at vast distances we are seeing light emitted so far in the past that even if we could teleport there right now it would look almost if not entirely different than images show. Always was amazing to think about how telescopes are literally time machines into seeing the past. Unfortunately in order to see these things we can only see them thru this "time machine" due to the cosmic speed limit.

Unquestionably, galaxies billions of light years away which light we're now observing are revealing their younger state, & may be presently structurally dissimilar now than how they currently appear. Unfortunately, the fact remains that our current limitations, & perhaps for decades to come, inhibits us from ever visiting any of those majestic beauties given our short lifespan.
Is this image related in any way to the Hubble Deep Field?
This may a while, Meghan. since you recorded this, but your observations remain crisp.
and light i have always been facinated by light and nebulia
Listening to a Mario Galaxy medley while watching this. Beautiful!
I love the 'asteroid photobombs'.
This is a scientists question. Galaxies form the same shape, suggesting they are alive. I believe they are alive. There's logical sequence in plant life on Earth with the fibonacci sequence. Is there a logical sequence with spiralling galaxies, too? As they spiral, do they all have the same amount of spiralling arms? (UK)
Is there maybe a link to get one of those posters? I am really interested. Keep up with the cool content!
OMG that's my instrument! :D (well it was my instrument when I worked there) I was starting to get suspicious when she mentioned the size. Awesome.
Please do a few videos on Lanikaea!
thanks
