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!!

[@DeepSkyVideos]

Higgins2001 thanks

[@subh1]

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.

[@danielmocsny5066]

"Carnies" are what it takes to do carnivals.

[@nicolepauline7595]

It's sad really

[@stefanschneider3681]

That‘s the beauty of your videos: Listening carefully, being serious about the science, but every once in a while asking a personal question. And there you can see the fascination they still feel about it in their eyes and faces. For me I got a glimpse of that when I pointed my camera with the 300 telelense on my mighty StarAdventurer star tracker at M 87 in the virgo cluster. And after stacking 50 pictures, out came dozens of galaxies around this beautiful elliptic galaxy, in every single corner of the picture! It‘s a perfect beginners target, and I loved it 🤩!

[@BirdSpyAustralia]

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.

[@DeepSkyVideos]

BirdSpy Aus thanks for watching - I really enjoyed making this one because it tells us so much about a real science research project

[@Dataacid]

[@windranger8226]

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 !

[@Etaukan]

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.

[@Zw1d]

More from Mrs Gray! I could sit here and listen for hours.

[@MrZizilis]

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!!!

[@JustOneAsbesto]

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.

[@pcuimac]

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.

[@marzcorp]

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!

[@JustOneAsbesto]

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.

[@danielmocsny5066]

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.

[@PacoOtis]

What a delight to have someone this dedicated and this smart and well spoken narrate a video such as this!! Thanks and please carry on!!!!

[@UmEatMyShortsPlease]

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 :-)

[@roxydzey]

yeah i felt that too. calmness.

[@swill128]

I could look at space pictures and listen to astronomers talk about them every day for the rest of my life and die a happy man. Thank you Brady.

[@DeepSkyVideos]

Am aware it maybe should be "tens OF thousands OF" but that is not quite such a snappy title in English!

[@SuperSampling]

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

[@pcfreak1992]

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".

[@SuperSampling]

pcfreak1992 thats true :D

[@paulmichaelfreedman8334]

And in dutch it would be "tienduizenden"

It just makes me happy to know there are people in the world studying this stuff. Keep up the great videos!!

[@mikeh6876]

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.

[@Nikola16789]

I like your dedication and passion. Great videoclip, I enjoyed.

[@noemiyesfir4177]

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!

[@sockmaster2718]

Fantastic. One of my favorite videos so far.

[@poesboes]

What a wealth of phenomena in such a limited patch of sky! Thanks Mrs Gray and thanks Brady!

[@freddan6fly]

I love listen to Meghan, she explains so clearly. Great video. Why is this recommended 6 years after it was created?

[@ocelotMartinez]

I love to hear Dr. Gray explain anything

[@monster2slayer]

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!

[@thedude7371]

This is by far the Best video I've seen for years. Thank You so much for this.

[@werdwerdus]

this is probably my favorite Deep Sky video you have ever published Brady!!!

[@babyfishmoul]

I think this is my favourite Deep Sky Video (it might be a tie with "More and more and more stars (M30)". I've watched it about 60 times, maybe more? It is so very interesting and Dr. Megan Gray is such a great (astronomical) story teller! Keep making these, please!

[@danielmocsny5066]

If you were to watch it 10,000 times, that would be one for each galaxy.

Thank you for sharing such a beautiful image.

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.

[@danielmocsny5066]

We don't even know the dirt under your fingernails fully. Human ignorance is abundant at every scale.

[@recterbert]

One of the most amazing videos. Thank you Brady.

[@Neueregel]

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

[@billschlafly4107]

[@АндрейБеньковский-ш5к]

"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.

[@amcghie7]

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.

[@platonictesseract6884]

Wow. Just wow. Especially the bit with the Einstein ring. I have never seen a picture like that.

[@celtgunn9775]

I absolutely love this image. I was one of the people who kept going online and help find galaxies as well as bubbles in the gas clouds. I miss doing that. Beautiful images...

[@RXP91]

More of this woman please! I find her accent mesmerising

[@laurahicks9558]

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.

[@seanehle8323]

Thanks so much for these videos. :D On the whiteboard behind Dr. Gray, there is a drawing of an H-R diagram with (what I think is) a track line indicating the evolution of a sun-like star. I would love to see videos about both of these things: H-R diagram, and evolution of the sun.

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. :)

[@malliyana201]

Dr. Grey is so pretty - anything a normal person says she can say it prettier :P Love listening to her!

[@inversnone]

To look at galaxies as if they were grains of sand. Mind-boggling.

[@superdave54811]

This only strengthens my idea of galaxy formation through the accretion of the smaller dwarf galaxies as seen in the distant visible universe, dense populations of these smaller galaxies. Only closer to us do we see more and larger developed galaxies, which are still munching on other galaxies.

[@ThimbleStudios]

This is funny to me, my third grade teacher told me that outside our galaxy there was nothing, that it was the entirety of the Universe. My eighth grade science teacher told me there were hundreds of galaxies. Now, we know there are hundreds upon billions of them, and our Universe itself may not be the only one. Fascinating.

[@danielmocsny5066]

Wow, I'm impressed by your apparent longevity. It sounds as if you went to school during the 1920s when astronomers finally resolved their argument about whether galaxies were merely like the other nebulae in the Milky Way, or whether they were distinct "island universes" like the Milky Way itself (a term used by Immanuel Kant in 1755). Or perhaps your teachers were sharing information that was somewhat out of date by the time you went to school.

[@duhast43]

What an awesome episode

[@bipinrana7116]

Love u from INDIA. LOVE UR EFFORT. UR APPROACH. thank you all who did any thing for this vid.

[@snarfsnarfff]

Imagine how much life could be in each of those galaxies. They could be teaming with life or... could be absolutely devoid of it.

[@JodBronson]

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.

[@lamebubblesflysohigh]

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 :)

[@visualdragon]

Dr Meghan Gray you are one of the people that make me proud to be Canadian.

[@m3grim]

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?

[@m3grim]

puncheex2 In that analogy, though, how far-reaching would the pull of gravity be from those stars?

[@puncheex2]

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.

[@warrendargusch5873]

[@colinp2238]

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.

All the sensors in our cell phones and most likely Brady's camera are CMOS, not CCD, but that brings up a question: are there advantages for CCDs in these applications? I know CMOS usually has less bloom, is cheaper and uses much less power, so why no widespread adoption?

This may a while, Meghan. since you recorded this, but your observations remain crisp.

[@HummingLoud]

The mind boggles. And I find it very frustrating when I can't get past the boggling. But it helps a bit if I think of the universe as small. Put the whole thing in a teacup and look at it from the outside. Thinking of galaxies as sub atomic particles seems to help.
