CybranM When the object in question is a galaxy, it has to be presented by either Dr Gray or Dr Smethurst, since they're both experts on galactic astronomy 😄

This has always been my favorite galaxy, and I've been waiting for this video for years.

Brady, I absolutely *love!* when you do videos with Dr Merrifield, Dr. Meghan Grey and Dr Becky Smethurst! I'm a galaxy geek big time! Oh and I really enjoy Kevin on Objectivty too. Old objects just speak to my soul. Is there any way you could do more videos in one of these subjects? Or maybe somehow put me in touch with one of them for learning? I'd so love to dive in and just be. I'm a housewife with fibromyalgia & degenerative disc disease so I don't get out much due to my physical pain. But my brain sure doesn't hurt when engrossed with galaxies & such. I've spent many an hour with Galaxy Zoo. I just can't get out & about. Or I'd love to retrain myself for this sort of thing. Lots of love from SW South Dakota! 🌱Be Blessed ღ 🌼

More deep sky videos Brady! Thanks for this channel ... I just love the content.

Truly amazing! Thanks, Becky, I could listen to such explanations all day long.

Really interesting! Your enthusiasm became more evident and contagious as the video proceeded. This kind of information adds to the the observation enjoyment and deeper understanding to us amateur astronomers. Thank you Dr. Smethurst for sharing.

I photographed this galaxy last weekend and i was stunned. I wanted to learn more about it. And what a fantastic video I've landed upon! I would like to call it the pearl eye galaxy

M64 is my AP target for tonight. Fascinating. Thanks for the vid.

Amazing inner and outer counter rotations spawning nurseries like M42 and M16.

Lovely video, thanks!

Thanks a lot for that video! Black eye is one of my favorite and even as a total astrophoto-beginner I really got a picture of it, just after I started to learn stacking. I have a very basic setup with an 6''-SC-telescope on an alt-az-mount, my daily dslr mounted behind at, processing the pictures on an MacBook 🤩 - but it's definately recognizable as the black eye galaxy! So much fun to learn how much is to it.

Ever since I first heard about/saw this galaxy, it has been my favorite one. Those dark dust lanes are absolutely stunning. Hence why it is also the one I've tried photographing the most times.

Cool and very detailed explainations 👍

The Braun ea. paper on NGC4826 paper mentions Dwingeloo in the opening. Wonderful location to stroll through the wood on the "walk of the planets" model Solar system, the whisper ears and finally the view on the synchronized row of radio telescopes. We don't do a lot in the visual spectrum here as the light pollution in western Europe is horrendous :) But it's our telescope. A piece of technical ballet if you catch the moment they all move onto a new target :) And I love the story of Oort and his buddies creating science from looking at the stars just a little bit different.

Black Beauty Galaxy, or Ravens Feather Galaxy would be great names for it.

Interesting arrangement of spins and scales.

Awesome series

great video! In general, I'd vote for a bit more discussion of the reaearch techniques used to figure this stuff out... like in this case a little more on Vera Rubin's methodology, either in main video or supplement.

How about this for a reason why astronomers are so enthusiastic about their work. The human race has two possible destinies. We either travel to another planet, and continue to grow. Or we don't travel to another planet at all, and eventually become extinct like the other 99% of all living organisms that have ever inhabited this planet. This is not a false dichotomy. Based on what we know about about our planet is that its made every other dominant species walking on it extinct.

Great video! Just one thing I'd like to point out. This video has a rather unflattering green tint. Maybe it's due to the lighting.

Looks like white balance set for daylight, but filmed under fluorescent lighting. Probably tried to rebalance in post, but that can look even odder if overdone.

I've heard you say that 'flocculent' means 'fluffy' before. Up to a point, that's true. I've looked in the full Oxford English dictionary, which says that it can also mean containing short woolly tufts. I think the latter meaning fits flocculent galaxies better.

You made a very good choice with the fellowship thing.

Nice, this came out on my birthday. I'll consider it the present I didn't know I received.

Flocculent; I have a new favourite word

I love the descriptions used such as _Flocculent_. Perfect use of the language. Although, I think you'd spark the imagination of a few children (and perhaps the odd 'Furry') if it was called a *_Fluffy* Spiral Galaxy_. Great presentation. Thanks for the upload +DeepSkyVideos. Oh, just an edit but had to check first. *Vera Rubin* was born 23 July 2028 (Not 2016) and died 25 December 2016. She was eighty-eight years old. For those that have never heard of her, I suggest you go check her out, as well as my other two favorite female physicists of the 20th century, *Cecelia Payne* and *Lisa Meitner*

Yes!! A neew one! Thx.

Well i just learnt something new. A counter-rotating core!! Thats wild

Nite pool diving and looking up - a cow pie floats where a street lamp shines down & thru.

Gorgeous galaxy... With an interesting name

Also, this is probably the best Becky vid, I think! Still would love to argue with her that Vera's proposed name change is a great idea though 😂 this galaxy is way too beautiful to have any kind of negative connotation 🥰

what a beautiful galaxy :o

Evil Eye Galaxy just sounds too cool. That's the kind of Galaxy for a sci fi setting.

Awesome :D

Coincidentally, M64 was just recently the APOD.

I looked at this galaxy recently in a 30 inch telescope. It does look like a black eye.

It is like Bally bowl in behaviour or say in working.

She's brilliant

I love Vera Rubin, but why the Sleeping Beauty galaxy. Usually specific names like that mean it looks specifically like that image or object and I don't see a sleeping beauty? Do you?

Could perhaps call it the Nazar Galaxy (as far as I'm aware "Nazar" refers to a talisman for warding away evil and its shaped like an eye)?

Dr Grey has said all his before she's the queen! :)

I created a whole bunch of theoretical alien races and planets for this galaxy

To be clear, Vera Rubin *Never* advocated for "Dark Matter" as a cause for the anomalous rotation curves of Spiral Galaxies. In fact, right up until her death on Christmas Day, 2016, she insisted that more evidence is needed to attribute the observed rotation curves of Spiral Galaxies to Dark Matter.

I would like to hear more about Vera now :)

@bill-zy6dg

Also check out Fritz Zwicky. he postulated Dark Matter in the early 1930s to explain the gravitationally anomalous rotation in the Coma cluster, he even coined the term (Dunkle Materie). Also his theoretical work on supernovae, neutron stars and gravitational lensing was decades ahead of his time. Allegedly an irascible coot, he got no respect and even today he often gets little mention.

4:46 Vera Rubin was born in 1928, July 23

Call it the 'shiner' galaxy. Everybody happy.

Shouldn't this galaxy's compound rotation be slowing down?

Your videos are great, you should get more views for sure

Forgive me for being naive but wouldn't the same effect be visible if the center of the galaxy was spinning out of sync (either proportionally faster or slower) with the rest? Like that would give the same effect without the center having to spin in a different direction?? How do they know it's spinning in a different direction?

@donaldnguyen9159

Marcus Nogaj 2:35 explains how they know it's spinning in different directions. Different Doppler shifts gives the absolute radial velocity of the gas towards or away from us. We describe rotations use a static axis frame, not a rotating one, because we observers usually want to describe from outside the rotating system and inertial relativity does not apply for rotating frames. This means the retrograde rotation in outside frame doesn't equate to same physics as forward rotations in a rotating frame.

True tail (spiral arms) of heroism in Science.

Curious accent Dr Smethurst has, sounds like a merger of Lancashire and Kiwi. I suppose with each being in a different hemisphere they'd be rotating in the opposite direction respective to one another :)

Stars and gas are rotating in opposite directions. I assume this would lead to an explosion of star formation, might be why there are no discernible spiral arms.

And Galaxies love you - they told me.

I've never before felt a kinship with a Galaxy. Now I do.

Personally, I'd name it the Boston Cream Donut Galaxy

Only Astronomers could give a super boring name to something super interesting like dark matter and yet at the same time have such an eloquent name for the word, "Fluffy."

I view planets orbiting stars but I've yet to view a galaxy. I don't have sophisticated enough equipment to remote track celestial objects or anything for that matter. I view everything by luck and chance. Thanks for guiding me in the right direction to look. Hopefully I will be able to post a video of a galaxy soon. I hate CGI. If I see one I'll upload it unedited in its original glory for everyone to see.

Ok I understand it. Why is it not possible to have storms in a galaxy? Asking for information.

I have been feeling rather flocculent as of late.

When a kingfisher flies straight past you, it's blue as it approaches and red as it recedes. Coincidence?

I now have a new crush. 🥰

Something seems really off with the color in this video.

No clue.

As Mr. Spock would say, "Fascinating".

The evil donut Galaxy

There are some beautiful and mind boggling things that are amazing in this universe. And the galaxy is really cool too 😍

Interstellar gas would not be an issue for any planets close enough to the star to be in the habitable zone. The solar wind from the star would be orders of magnitude more powerful that close in.

“The Coiled 🐍 Asp”. 😎👍. Top notch name for a galaxy... 😔just not this particular one. “The Coiled Asp”, as it is a snake, connotes being solidly ropey & smooth. This galaxy is far too fluffy, feathery, & poofed out to evoke a smooth scaled serpentine body, & it’s also not at all easy to see the individual spiral arms (in other words-there’s not any kind of coiled up body to be seen within this entangled meshy thicket of dust). So it is a superb name for just about any other spiral galaxy except for M64. As for a new nickname-I happen to like “The Black Eye” galaxy as it stands, but if you're hungry for another name featuring a badass, fear-inducing animal, how about: “The Vulture Nest” galaxy.😈

Lass is awesome.

It seems kind of naive for an astrophysicist to not consider spiral galaxy merges given the timescales involved, but then again, I'm no astrophysicist... Great video as always.

@SuperFlamingTomato

It's less that they couldn't merge, and more that they couldn't merge to create another spiral galaxy. On the surface it makes sense, you'd expect structure to be destroyed in such a collision, but it turns out in certain conditions it actually can create, or at least retain, some spiral structure.

But why, though? Why would you expect the structure to be destroyed when we're talking timescales of billions of years and when we're dealing with structures that have such immense angular momentum to begin with? I think you guys are answering something I didn't ask, so maybe I was unclear.

@SuperFlamingTomato

6 жыл бұрын

Well it's not as simple as a flat disc with a certain angular momentum and a defined centre of mass colliding with another flat disc and merging, these structures are made up of, for the most part, stars and nebulae. Each of these mini structures is bound to interact in a way that would be different than how the overall structure would interact, given the same conditions assuming a flat disc. Imagine you had a large disc of rotating sand, held together largely due to the rotation creating a stable centre of mass, colliding into another large disc of sand, you'd expect sand to fly everywhere and maybe you end up with a blob. This is why this would only happen under specific conditions, because it isn't the norm. You need particular ranges of momenta, angles and size (mass and density) to create this interaction. Otherwise, for the most part, you do end up with globular clusters. If maybe this explanation still doesn't make sense, most models predict globular clusters forming. Additionally timescales don't matter too much here, physics on this scale is mostly scales if you increase time, unlike say viscosity here on Earth.

@buttsufancypantsu1644

6 жыл бұрын

Thanks Thomas! I have a follow up question: is it expected for non-spiral galaxies to remain that way forever or would most of them eventually conform back into a disc? That was my confusion regarding timescales. It seems to me like a spiral configuration would have less net energy than a more chaotic system, which is why I assumed galaxies will "strive" to become spiral galaxies if given enough time.

Wonderful video and explanation.... P.S... Very beautiful eyes as well :)
