- What the fork is going on in this galaxy?! It looks amazing but we still don't have an accepted theory for explaining how these rings form. Let me take you through a couple of our best ideas.
And whoops, had a brain typo halfway through this video. Hoag's object dimensions should be 17 thousand light years, 75 thousand light years and 125 thousand light years.
This video was inspired by a comment on this video: • M58 - The Ring Bearer ...

Whoops - had a brain typo half way through this video. Hoag's object dimensions should be 17 *thousand* light years, 75 *thousand* light years and 125 *thousand* light years - d'uh.
What's a factor of a thousand between friends :)
Piddly factors.
dawww i thought it was a tiny cute galaxy.
Weird, my brain heard the thousands. Maybe I was just expecting them?
That made me curious, is there a definitional upper and lower limit on what constitutes a galaxy? Like do you need at least a certain amount of stars or volume before it's a galaxy and not just a.. lesser-axy? And is it conceivable that there could be a galaxy so big that it would be more correctly categorized as part of some superstructure? Is there some kind of galactic roche-limit?
Imagine being an astonomer living in Hoag's Galaxy and looking out in the skies, wondering why the hell all the other galaxies are different.
Well, they do have "SDSS J151713.93+213516.8" , aka the ring galaxy we can see behind Hoag's galaxy when we view it; a lottery winner booked up with a lottery winner than can probably see each other.
We're already in a very similar situation. Our Solar System is quite unique in comparison to the majority of other systems we've found... and it certainly leaves us scratching our heads.
Depending where you are in Hoag's Galaxy, you might not know the misfortune of your own shape.
@@Strype13 How is the solar system unique?
@@locoattack1210 The Oort Cloud,the amount of planets we have, etc
There's something deeply satisfying about the fact that Mr. Hoag lived long enough to find out what a marvelous discovery he made.
It's an amazing coincidence that we have such a perfect, polar view of it.
The greatest cosmic coincidence is that Hoags object and the other ring galaxy are both perpendicular to us allowing us to view them in detail.
Not a cosmic coincidence. Those are the rings that Starfox flies through to get his power-ups.
Hyaaaaaah!
Question: How would a ring Galaxy look to us edge on? Would we have any way to difference it from a spiral?
This is what I was wondering as well.. many of the collision galaxies shown seem like they could look identical to the Hoags Galaxy if pictures at the right angle.
I think it would look more like... a ring planet, or, those pogo jumpy ball things. Where as a spiral galaxy formed as one unit, thereby having a more gradual connection between the core and the arms/ body; with a 25 LY gap in between the two, seen perfectly edge on, it would likely look like a ball with a plate through it... muck like a Saturn, except, well, a galaxy.
@@faulkgough1768 Did you noticed the correction (by Dr. Becky), this galaxy is actually 125 000 light years (not 125) and gap is 58 000 light years (not 58)
@@vesa.tamminen yes, yes, I did. The Milky way is 100,000 ly across. where she did not correct in the post is that does not make it the 20 some odd times bigger. She made a very good video, goofed on a few numbers, but still got her point across.
@Faulk Gough She said "it's about 25 percent bigger" not 20 some odd times bigger.
Just discovered your channel. Great presentation, clear with great supporting images. Also love your enthusiasm. Thanks.
I've never heard of ring galaxies before. Thanks for introducing me to these objects!
Great video again! And the sound is so much better now with the lavalier microphone. One remark: the distances in the image (and your narrative) should be in kly (kilolightyear).
I had to watch this three times before I could hear the words . Her beauty keeps freezing my mind. 😍
It is amazing how much the production quality of your videos has increased in just a couple of years.
I have subscribed. I love to hear about unusual objects in space and like cosmology videos. You make it fun and just looking at you is a pleasure.
In your video about the cartwheel galaxy you kinda said that it trumps Hoag's object. Glad to see you pointing out how beautifuly symmetric and aesthetic Hoag's is in this one! And the other distant ring galaxy visible in the gap! The cartwheel might be more interesting to your research but in my opinion Hoag's object is near the top of most beautiful things we've observed in the universe 🥰 gives me goosebumps every time I sink into images of it

I caught that typo too when I thought, "Wow, only 125 ly across, only enough room for a few 100 stars or so..."
Love ya Dr. Becky!!! Your videos keep me interested in pursuing a research career in Astronomy & Astrophysics 😄
I subbed because you are so smart and your videos are incredibly packed with info. Plus, I find you so adorably cute. Keep up the great work teaching us plebs about our universe!
Hey Dr. Becky, just found your channel and love it. Just curious, since I watched this video, after watching your video about dark matter in black holes. Could the ring be a space of dark matter, since it doesn't collide and spiral down as quickly. If so, would that be something possible to test in anyway. Disclaimer: I'm not a physics person, just find the various concepts you talked about fascinating.
Fascinating stuff.
Dr. Becky, Thank you for sharing your knowledge with us. I truly love astronomy so much! I've watched you & Brady from the beginning. Will you be doing more images & such in your Galaxy Zoo ever again do you think? Finding galaxies and bubbles were just so much fun.
This Hoag's object is gorgeous. Interesting to learn the various ideas being tossed about on how Hoag's object was created.
I been fascinated by that photo for a long time. Have been looking at other galaxy photos too. Your explanation was very clear and I understood all of it. Love it. I guess I been watching to many astronomy videos,. New sub.
Hey Becky, I know there is already a video on M104 on DeepSkyVideos but is M104 also a ring galaxy? Or can we not say that, since we are looking at it from the side?
This woman is just as awesome as anton petrov channel
In 1600’s Europe, she would been taken for a witch for her science knowledge and appearance.
With a big difference; she's actually a scientist who knows her stuff. Anton is a wonderful person, but lacks the knowledge and education level of Becky, which shows in their videos. It is (probably) fun to watch his channel if you have absolutely NO knowledge about astronomy, but if you do, you gonna get annoyed by his videos at some point :-)
@@merveilmeok2416 She looks like a witch to you? Jeez

Wonderful presentation, easy to understand and keep up with, glad I found you
You should look in a straight line from the center of Hoag's, and the other more distant ring galaxy. If there's more in that line, then it's probably just from Thor throwing Mjölnir across the universe.
There's possibly a lot more truth in what you said than you thought. I've noticed that things form in strings in the universe . . . part way through I was thinking look in a line to see if there's another one.
It does look like something huge shot through it. Maybe a supper massive black hole, or holes, are in orbit around the central core and either ate all the stars or pushed them inward or outward.
@Don Mac
It's AMAZING how many people out there have dreams/ visions/ near-death-experiences where they see Loki, but these foolish people misinterpret what they see and they _think_ they're seeing Jesus instead. Silly, silly, gullible fools!
@@Raz.C.... If I saw loki, I wouldn't think I had a near death experience. I'd think someone slipped some LSD in my beer.
@@thomasfleig1184
What I'm getting at, though, is how would you know if you saw Loki? For all we know, the Germanic people got it right and Loki, Odin, Freya etc... are the only real gods and the only reason anyone thinks otherwise/ believes in christianity/ islam/ thinks they saw jesus/ Vishnu/ etc is because of Loki's trickery.
Great video Dr. Becky! I wondered throughout the video how dark matter affected the strange formation of this structure. Did the recent paper use dark matter in their simulations? If they did, how do they know where the dark matter is? Seems like assumptions would have to be made. Also, for a "clean" gap in a ring system, we have seen larger, but perhaps not obvious bodies, sweep out a clean section. Some of Saturn's moons create this affect. Maybe there is (or was) something large (black hole/s) that are hoovering out a section! Just spitballing here, but what an awesome system!
A pair of large size black holes orbiting each other 10k ly apart, orbiting the core, would have sucked up all the gas, and ejected all the stars, from the empty ring.
If two of us think this we must be right. How you gonna spend your Nobel windfall? I'm gonna build an airship.
Their orbits would need to closer the 30,000 LY and their mass would need to be in the 100’s of billions of solar mass to achieve this. Also when they spiralled down they would either interfere with each other and launch one or both into deep space and/or merge and the resulting blast wave of billions of solar masses being lost in the heat caused by this merger that we’d easily detect such an event clear across the universe assuming it was within our apparent horizon. I’m not sure this has been ruled out but since it’s reasonably obvious, but ludicrous, some first year has already tried and had the idea shot down, (probably hundreds of such students actually). I thought of this as well, but dismissed it for those plus dozens of other reasons, but definitely a really cool idea, just imagine it!
Good point. Maybe this galaxy will end up being the key to understanding dark matter.
Btw they CAN and DO measure where dark matter is by it's gravity.
Excellent and very informative!
Learning so much new stuff about our universe.
Thank you!
Thank you for making your videos interesting but also easy to understand
It seems odd that the other known ring galaxy is so close in angle to this one. Has nay one looked along that line of sight in the opposite direction to see if there are any ring galaxies out that direction as well?
And while on that topic is the orientation of galaxies random or is there some pattern or commonality among them?
Ron Wilson there are some patterns
Here is a good video
At 4:53 - If the overall dimensions are 17/75/125 kly the gap would be 58/2=29kly and the ring would be 50/2=25kly wide.
Thank you! An extraordinary report!
your eyes are brilliant like this galaxy. thanks for the science :) always nice to listen to someone who knows they're talking about, talking about something they find interesting.
In the second theory you provided, similar to how we think planetary rings like Saturn's form, could there be some mechanism that the collision could drag the increased hydrogen concentration out of the elliptical core galaxy?
**edit**
I was just wondering this very moment if there was some "third party" galaxy involved that got flung out of orbit, but I would think there would be some traces of such an object, even if an event like that happened billions of years ago. Unless! It was mostly composed of dark matter! Seems like a crazy number of coincidences, but then again, this seems like a pretty extraordinary object.
I was thinking that, too. A galactic-level Roche limit? I don't know the maths well enough.

@@snowballeffect7812 Dark matter crossed my mind as well... Perhaps a combination indeed.
Mr. Worf, program a level 3 probe with a trajectory into the anomaly and launch when ready.
Cool. While intuitively it would be super rare, what would happen if two smaller but similarly sized satellite galaxies with a similar orbital plane encountered an elliptical galaxy at the same time and happened to be at the perihelion and aphelion of the same orbit? Could they essentially unravel and eventually stabilize into a ring like structure?

Awesome video, Doctor! Super informative!
THE PERFECT CHANNEL AT LAST! Im sure im gonna like this vid : 3
p.s. please get a 4k camera (upload 1080 if you like, but get the 4k version)
What if the outer ring accreted slowly, but in a retrograde orbit compared to the spin of the central core? I'm imagining things in the gap between the ring and the core interacting gravitationally to clear those orbits, until there's nothing left to interact.
Counter-rotating gas would slow down via friction between the two directions, and fall inward, creating a smoothing 'blanket-like' effect on the inner core. All that would be left would be stars, and not nearly as many since there'd be little gas left for star formation, leaving a very empty ring in between the two counter-rotating masses.
Could it be possible for this to form based on a very precisely aligned (and slow) collision between a small elliptical and a larger (but not very dense) spiral or disc? If the angles were just right, it could almost be like the semi-stable vertical oscillatory orbit through the center of a toroidal body, with the two oscillating until they stabilize, then smoothing out over the course of a few more rotations.
It also reminds me of the way a planet clears its orbit, though I wouldn't think that would leave such clean and even distribution.
1. get the numbers that represent your hypothesis
2. do the math
3. publish the paper in a peer reviewed journal
4. brag that you "solved one of the mysteries of the universe"
(Sounds plausible enough to be worth falsifying)
It's not a result of anything gravitational. Gravitational interactions cannot account for accretion of stars from gas clouds much less the observed structure of any galaxy.
It's an electrical phenomenon. The plasma current feeding that particular galaxy is what gives it the structure observed.

Your theory could be verified by long duration observation. If you have tge resources you could set up an observatory and make a lot of observations over several years. Then you coukd determine the movement of the ring structure. Of course determing the movement of the center mass requires very high magnification and resolution immaging. That means you need a very powerful tellescope.
Hoag's Object, is that a Black Hole you have captured in the middle of you, or are you just smiling for Earth's cameras?
I'll take "what does Dark Matter do" for $500 please, Alex.
Also stop lighting your eyes like Hoag Objects, that's just not fair. :p
Thank you for making this interesting video. I've never heard about ring galaxies before so it was nice to learn something new again.
This is fascinating! There are so many possibilities of different structures in our universe... it's really mind blowing!
Question: is there any explanation to what seems to be a concentration of mass on the bottom left (7 o'clock) on the outer ring?
Still waiting on the discovery of Hoag's Boson.
It's speld" hoax "boson
Surely you mean the Hoag's Bison.
Hog Buffalo??
I'll get on lit, as soon as I'm done with Hoag's Hoagie.
Or, the Higgs Bison.
Have any of these Hoagies been discovered that are NOT center-on to our point of view? Are there any that we observe at an oblique angle? If not, doesn't that seem impossibly coincidental?
Well, there have been a couple Ring Galaxies discovered of that type, however, we have never knowingly observed one directly head-on, and that's because there is no way of telling say The Whale Galaxy or the Cigar Galaxy of their galactic shape, as no defining features or characteristics are inherently visible. It's why we still don't know the nature of the Milky Way for this same reason. We're directly on the galactic plane of it.

Good luck with the research and growing your channel.
Larry Niven:- Hey, my Ringworld is cool, 180 million miles diameter, a million miles wide!
Arthur Hoag:- Hold my beer.
Over the last couple of decades, we’ve all had beaten into our heads that galaxies are embedded in halos of dark matter and that dark matter drives much of large scale galaxy dynamics. In your discussion of Hoag’s object, I did not hear you talk about dark matter. That orbital dynamics model, with a forbidden zone, seems a lot more speculative if we have to assume there is a dark matter matter halo with several times the gravitational mass of all the normal matter. What would that do to the orbital dynamics?
Dark matter is an astronomics mathematical kludge.
Caldwell Transport Columbus, GA I don’t think calling dark matter a kluge really describes the situation usefully. We have, beginning most importantly with the surprising observations of galaxy rotation behavior by the late Dr Vera Rubin, good evidence that galaxies are surrounded by something creating gravity, a lot of it. Nobody has yet observed, despite looking hard, any sort of normal matter, matter that interacts with light, to account for this gravity, so the name “dark matter”. Perhaps a better name would be invisible matter, or invisible source of gravity, but whatever the name, there is something out there in space that we have good evidence for, but no explanation.
@@markholm7050 Or... our maths are wrong. But its much less embarrassing to say there is something wrong with the universe instead. So lets assign it an arbitrary bit of extra mass and energy so our equations match what we think we see. A "kludge" is accurate.
Prime dimensional space-time could be the answer for dark energy and dark matter.
Prime one space time is a nano.
If one can conjecture of a universe of Chaos in the Nano phasing of the Prime universe possibility.
Imagine, or if you think about it, is there a possibility of a scale of astrophysics that is really really big.
Bigger than all of our best instruments will ever be able to tell us.
Within each Nano is the chaos of possibility and that we are stuck in a 3D Prime Nano space time.
Since there was no Doppler shift looking for the center of the universe with the Big Bang Theory,
Other kinds of universal interactions four theories are at play.
What if all the possibilities of the Nano space time exist in the chaos field, but we live in a long time compared to the time of the phasing of the Nano space time.
So prime one, is that so-called Big Bang Theory thing. And prime one is still in existence but not for our 3D sentient bodies. Everywhere in this verse prime-1 exist for part of the phasing of the Nano cycling in the space time continuum.
And also, Prime 3D, Prime 5D, Prime 7D and etcetera Etc all going on within a billionth of a second in a nano space time continuum.
If one uses the rubber band affect in the possible interaction of the Prime dimensional space within the Nano space time continuum, there could be a theory that sets up how the universe is constantly in chaos with dimensional Prime space, and as always returning to the zero-point reference of the non chaos universe within the Nano space time continuum.
We don't understand the principles behind all this, yet. But it starts making sense, if one learns of the entanglement Theory, and the idea of time being a product of matter and energy interacting in the Nano space time phasing Covenant of the properties of the universe. In other words, in order to understand the grand large, one has to see the greater small.
The phasing of the Prime dimensional spaces of the Nano chaos Matrix is what is in the mathematical mind of all the genius on the planet right now. These are very Advanced ideas, and the mathematics require a helping hand.
When and if AI become sentient, this will be the grand question for AI to bring to the halls of Academia to take us again into a technological future.
Once again, will have the flying carpet, the genie with the wishes, and the Open Sesame world of widgets.
And the children of the whole wide world are watching
The calculations on where stable orbits exist apply equally to dark as real matter. The models of mass distribution are just as valid even if we can't see the majority of the mass.
Very cool. Every little thing you find out there creates a lot of hypotheses and debate, which progresses our knowledge of what is what in the cosmos.
YOU arr bloody good at explaining cool stuff Becky and you have a passion for it, you deserve a lot more than 6.4k subs
Or, to go more SFIA on it... what if it's an alien species that can build Dyson Swarms, but either can't or don't like to colonize those older core systems, maybe due to the more intense radiation, or maybe they just lack the resources they need... and also are leaving the outer star-forming regions alone for ethical reasons, in case new life emerges there in the future? Do we have a nice crisp infrared image of that galaxy? If there are IR signals from the "gap" section, this theory could be plausible. If the gap is there in IR too, then not so much. XD
That would drasticly change the mass of the whole galaxy and mass distribution. The orbits of the ring would be different.
Or if there is no IR signature, maybe they constructed stellar engines to move the star systems closer to the core, so as to reduce communication and travel times. Maybe they're constructing a Birch planet... Its nice to dream.
It's never aliens

Amazing stuff. Thanks for posting!
I wonder if this is a hoags..
I groaned but it was worthy of a thumbs up.

I appreciate your descriptions of the processes that
are in play here. I am in the beginning stages of hypothesizing something related, but different. It is no coincidence that there is that gap between the center and the ring. I wish I could GO there. How spectacular would that be?
Beautiful explanations from a beautiful mind.
Honestly, I think everyone is thinking too small. It’s clear the central collection of blackholes that’s in every galactic core have merged into one. The resulting gravity has sucked the inner material into a giant accretion sphere. The resulting radiation from all that material falling into the central blackhole creates a massive galactic wind that pushes all the rest of the material into a ring and compresses it into a hot star forming area.
I wondered that as well, but thought the distances may be too great. At the same time I also do not want to underestimate the power of Supermassive Black Hole collisions and what they can do to free floating non bound hydrogen gas. You may be right.
Stars can't be moved that way. It only works for gas and dust.
@@stefanschnabel2769 I'm not sure that's entirely true, but in any case the gravitational exclusion band described in the video would eventually pull the stars out of the empty area. It wouldn't clear out all the dust though. However, a shock-wave from multiple stars falling into a massive black hole would clear out all the dust quiet quickly.
So thinking bigger , it is whitehole that pushed everything out to more stable orbit. It is lonely that pointing something and it has gas but no other sources nearby.
@@marsamatruh5327 I was literally about to comment this and decided to look at the comments first.
Come on, god created them on the seventh day, when he rested and puffed smoke rings around the firmament of the heaven.
Love this format, more astronomy pron please!
Thank You, Dr. Becky for explaining the mystery of Hoag's Object. I see some similarities between it and any classic spiral galaxy that makes me want to offer a hypothesis of how it formed. Please notice how the core looks "old" and the arms in the rings look "young". It is my opinion that the arms of a spiral are the discharge of the jets of the black hole, from the distant past, that has "condensed" into normal matter. If the black hole was a bit unsettled and the jets were precessing, then the product of the jets would be a double cone. If the "condensation" happened at just one distance, then the arms would form a ring as the jets precessed. And we, viewing it perfectly on axis, can see only one ring. The impossible orbits would clear themselves.
Does the butterfly nebula look like the side view of two cones to you? The jets lay down a bit more with each rotation. There are other examples of cone and ring formations.
No aliens, huh? Not even on a fringe note. A distant type 3 civilization having scooped out the inner, turmultous regions of their home galaxy and using the material to build in the farther more stable and benign areas. That definitely would be my go-to theory anyway.
I suppose its not impossible but thats your go too? You dont look for a solution not requiring insanely advanced aliens before just assuming that?
There seems to be a nature bias...but honestly we should lie about it just to unify earth.
Of cause not, @Poul. I don't live to be a million years - which is required if I want to find out which it is first hand. So I might as well go crazy on conjecture, quickly seizing on the disciplines of philosofy as a guideline to extrapolate on stuff I am able to observe. For example, consider that weird question, "do God exist?" Using philosofy, there is one answer to this, that in it's simplicity and ability to satisfy both religion and science, must simply be true! (Although, always keeping in mind also that "the only thing I know with any certainty is, that I do not know anything at all" to prevent me from growing too frustrated at the state of things over the fact that cosmological timescales laugh in the faces of even our gravest concerns. It simply doesn't matter a thing, when you get right down to it.)
The guys in the Thunderbolts project have the answer for these kind of objects.
Great, just point me to the journal for citation!
Yeah, they can even answer "what 2+yellow". The holy books also have a lot of answers to everything. But there is one problem with all of them : they actually just claim "this is the answer" withtout any proof, so get out.
They have many interesting hypothesis and simple explanations. Only the old dogmas claims to know it all. At least they ask the right questions.

An interesting video, Dr. Becky, thanks. I would ask, though, if you could post links to the papers you mention. Again, thank you for your work.
The last explanation sounds a lot like an exercise in elementary Catastrophe Theory; where you have two stable modes separated by an unstable (splitting) ridge. Nice lecture/explanation :)
Hoag’s object shows the detailed features of the ‘penumbra’ of a plasma focus discharge. the ELECTRIC UNIVERSE can point to a simple explanation, which fits neatly the plasma cosmology model of formation of galaxies in a magnetic pinch at the intersection of cosmic Birkeland current filaments. It's not a mystery at all - the only mystery is why anyone is stil clinging to a gravity centric cosmology when the magnetic signatures of vast electric currents in space are plain to see www.holoscience.com/wp/electric-galaxies/
Have you studied General Relativity? The electromagnetic field is a fundamental feature of the geometrical description of spacetime in GR.
So many words, so little sense.
Seachangeau. This new Electric Universe myth is becoming more like a cult, desperately trying to force Nikola Tesla and Jesus Christ into astrophysics. Have some shame, man.
Is this another conspiracy like the flat earth? It sure seems like it. Too much technobabble than any sort of explanation for their claims.
@@henzy7397 It is, they call it the Electric Universe. Most of their followers have never taken a physics nor an astronomy course in their lifetime. They think the universe is a vast field of electricity where galaxies are powered on by plasma cosmology. It's psuedo science.

@@ArdaKaraduman Still makes you look like a creepy stalker.
Nicely done. I would never have understood all those papers if I had attempted to read them.
I love videos that talk about subjects of active research, and this one is a major treat!
One minor "paper-cut" request: I worry that characterizing galactic interactions as "catastrophic" and talking about them being shredded and destroyed might lead to people imagining that it's a dangerous and probably fatal thing to happen to any possible inhabitants in the galaxies. When in reality, a tiny fraction of star systems would be disrupted by galactic collisions. The only thing that gets "destroyed" is the general shape and macroscopic structure of the galaxies. Maybe it would be better to talk about "distorting the disks into strange and beautiful shapes", and creating "interesting streamers and filaments". Possibly even point out that the star birth might lead to eventual new biological life in the universe, although that could get off-topic pretty fast. :-)
Thanks for the video!
Oh wow that billions of years clock is so mind-blowing to watch, to imagine how many millions of beings may have evolved lived, and died whilst those galaxies were merging. Cosmic time and distance measures are so huge!! thanks, Dr. Becky for another mind-expanding exercise :)
Great post!
Most puzzling! It may turn out that Hoag's object is so solitary has something more specific to It's apparent mass as a whole? And I would include 'Dark Matter' here too, which obviously plays a large part.
Of course, our own galaxy will begin to collide with Andromeda in around 4.5 - 5 billion years or so; probably followed by a huge galactic dance for maybe another 5 -10 billion years or so until it settles down to some sort of stability; but this is very difficult at present to approximate given the proximity of the rest of our Local Group also. Thanks again!

Hey Dr. Becky. I know you made this video a while ago but could you explain to me the last part of your video where you combine the theory from 2011 with the one from Bannikova? I don't quite understand what you mean. The reason I don't understand is because the theory from Bannikova suggests that there is a distance from the center elliptical galaxy at which its gravity stops interacting with other matter. But if that's the case, then how does the accretion form around the elliptical if its too far out for its gravity to interact? I'm struggling to understand. Thanks in advance!
Hey Becky thanks for the great video
Interesting video, very well explained
Dr Becky, thank you for such intelligent conversations! Could the inner clearing of Hoag's Object be from a black hole clearing out the inner mass from this galaxy? Sort of like how planets clear out mass from a solar system.
wow that is really technical cool and awesome you really are well educated in this stuff!!!
thanks for your good works
Great video Dr. and I have a question. Are the rings definitely rings and not spheres? All of the ones you showed were positioned perpendicularly to our line of sight. Did you just select those for their appearance? Because I am thinking that a sphere around a central mass might appear as a ring from all directions because around the edge you are seeing through a greater mass of the sphere's substance. Otherwise are there ring galaxies that appear oval because of their angle of tilt, or would some perfectly aligned with our line of sight appear as a line or like a disc galaxy seen on edge?
one of the better channels on yt
Lucky I’m that curious. Recently I saw a show which I could tell I knew even before it started. Because of all of these shows I follow . So thanks to all of you 🎸😊🎯
I love vids like this that make you think and ask the question, HOW ?
when i see that notification on CZcams that Becky has uploaded, i hit that like before that page even has time to load ;P
Hoag's object and your eyes are quite similar ....loved your presentation #awesome
so interesting!
just found your channel :)
Ahh yes the ladys love to dance! Thanks Dr.Becky for this introduction into Ring Galaxies!
Thanks Dr. Becky for the video. I think the biggest clue to this mystery is that 2 of the same uniquely shaped galaxies are closely aligned together. Which could indicate an unexplored affect between the galaxies and their surrounding area of space.
I'm glad you guys are all smart and stuff!
3:25
At 2:30(clock position) on the ring, there is another red ring which looks similar to the distant ring galaxy. Are they the same due to gravitational lensing?
The calming process for these odd galaxies could be a Type 3 civilisation... bearing in mind there are two of them in the same telescope shot; which can't be just coincidence surely?.... Awesome stuff here on your channel... Thank you...
Heart wakes up and feels alive again to see Dr. Becky, such a Shiny Star.
Very interesting video. Could something like this form from the inside? Like something super massive spunning very fast, and exploding, spewing it's mass outward and blowing things nearby away as well?
Very interesting topic 👍
An impressive amount of homework was involved in preparing this video.
Thank you for your troubles. :)
I would be curious if there is a significant age difference between the center and ring, its available for viewing on MAST from the HST.
Hi Becky!
Can a previously existing dark matter halo be enough of a trough to seed the ring in a merge event and lead to the gap due to allowed stable orbits?p.s. fantastic vid!!
