Can we just take a minute to appreciate the work ethics of Anton? He can take research papers 10's or 100's of pages long full of science language, and turns them into a 10-15 minute videos that can be easily understood by someone with a reasonable intelligence. And we can't forget the friendly smile at the end. I say, good work sir!
Yeah he knows how to talk to layman -I laughed the other day some guy trying to teach him English grammar misses the point
@@dug3557 And to realize his personal background?!! We have a very humble human being in our midst. I, for one, am incredibly grateful to this son, and father, for his time and knowledge that he shares with us mere mortals. He is truly a wonderful person.
Yes, Anton is incredibly efficient.
💚☀️🌍💚
He could just read the abstracts or summaries
Hello wonderful Anton. Thank you for the years of dedicated reporting you've done for the world. You spread goodness and it makes my days a little brighter when I get to learn from one of your videos. Thank you so much.
Tongue in cheeks..his😅
@@animalbird9436 Really, bro?! Credit to you for being here, hopefully learning/appreciating something new - at least for this planet - about this universe. Crass comments such as yours do not add anything to the conversation. Not even laughter. So, if you don’t mind…

It's pretty clear that these stars are just staying together for the sake of the children. Once the kids are off to college, they'll all go their separate ways.
Yes very true 😂
i think the current situation means the kids are staying around much longer than anticipated
Given the economy, star kids ain’t going anywhere.
😂
@@global_nomad.Cool
Anton is a true gift to humanity. I love you Anton you are just amazing and I can’t explain how grateful I am that you are doing this work. These are things that people need to know! Thank you for doing such an amazing job over the years Anton, you are such a wonderfully marvelous person ❤
What I would like to know, is how the night sky would look from the perspective of a planet in one of the satellite galaxies. The Milky Way must look fantastic!
The photos that you see of other galaxies are created from other wavelengths of light. If you have night sky somewhat free of light pollution, you can actually see the Milky Way with your own eyes. It's impressive, but it doesn't have the visuals that the satellite pictures have.
Seen it from Earth plenty of times (country viewing is excellent) but I would love to know how it looks from outside - as a whole galaxy, up close, not just edge on from inside. I guess we'll just have to wait until Andromeda gets a little closer to get an idea....
I hesitate to write this. I'm afraid it will dash some hopes. When you see the Milky Way from a dark, non-light-polluted , country site, that is how bright our galaxy IS. To the unaided eye, anyway. From our position, we could not get any closer; we are IN it, on the inside edge of the Orion Arm. When we in the northern hemisphere on Earth look out at the winter sky (those in the southern hemisphere look out at their summer sky), we are looking into the thick of our arm, and so we see most of the bright stars that we CAN see because they are relatively close. Nearly every star that we can see unaided, bright and dim, is in our arm. I think that Deneb, in our northern summer sky, may be in the next arm inward, the Sagittarius Arm. I could be wrong. The Sagittarius Arm is several thousand light years away, and the center of the galaxy is some 26,000 light years away. They are both unresolved glows without a telescope. If you were to somehow get "above" the plane of the galaxy, to where the entire galaxy could be seen in one glance, I am going to guess that you'd have to be about 100,000 light years away. The galaxy would appear to be about one radian wide at that distance (somebody please check my math). At that distance, you would not be able to see ANY distinct stars, and it would take some study to discern the dim clouds of the arms, and the slight brightening towards the central bulge and bar. I am afraid that astrophotography, and the artistic license of illustrators, have led us to expect colorful grandeur. Alas, we should not. NOT to say that the grandeur is not there, it IS; but it is quiet and sublime. Or would be, if we could get there to see it.
@@glennalderton1313 Funny that you should mention Andromeda. We're already close enough to view it as a sizable object in the sky. The moon is about 0.5 degrees across, whereas Andromeda is about 3 degrees across. It's dim, because of its distance, but apparently it's very easy to see with binoculars or even a basic telescope if you get away from light pollution.
@@glennalderton1313 Well i hope we get to see it up close, some way some where.
I wish I was still actively partaking in hallucinogenics. Those universe simulations are trippy enough sober...
Stay Wonderful, Anton!
Right watching his video high is fun 😂
@@cocolove9916ever seen a dollar bill on weed
Every time the explanation is dark matter, I roll my eyes and think "OK, they don't know." Dark matter has not been proven to exist. They might as well just call it magic, but it'd be more honest if they just said "We don't know."
"Dark" means "We don't know"
It is virtually certain that it is dark matter. Unfortunately, "virtually" can usually be translated as "not." So, not certainly dark matter, for real. 😂
I keep hoping that he will discover the electric universe. That requires no black holes or dark matter or any of the other virtual Explanations.
The electric universe theory
@@bradmowreader5983these types of videos make me angry beyond belief seeing your comment gives me hope
I always appreciate it when someone who has a great deal of scientific knowledge can distill it so that I, a lay person, can understand it and enjoy it too.
Here's a sci-fi movie idea. Like we have satellites around the earth, a species that's monitoring the galaxy created a mini cluster as a jumping point/satellite.
Ecliptic storm.
@darylbrown8834 what?! Is that a movie or random? Like..."shadowing weather condition"
I just want to say you work really, really hard and we appreciate it! =)
A collection of sixty or so stars, 10 light years across, with lots of planets, 10 billion years old, that should have fallen apart due to tidal forces but hasn't? Forget Omuamua. This is my idea of a starship!
I thought he said 16 😂, but anyways, does give me similar inclinations from the Isaac Arthur vids
Intergalactic colonisation expedition. Probably all their criminals being sent to a penal colony galaxy.
If that object has a lot of dark matter, wouldn't it cause major gravitational lensing, proving that it has dark matter?
It would still be just a dwarf galaxy, it's just that most of the matter would be dark matter. I don't think the other dwarf galaxies that are orbiting the Milky Way cause "major gravitational lensing".
Technically yes, as "dark matter mass" is estimated by gravitational effect per lensing making the unseen matter seem apparent. But, that is theoretical to explain the effects and rationalize what is causing it. Thus, observers would need to be looking for exactly what you are suggesting, they just wouldn't know exactly how that would appear so close as a dwarf galaxy, so the hunt for observable phenomenon will be on to see.
They are confident enough to claim they know the mass. It's an ongoing question I have where they calc the mass of galaxies & those masses appear to correlate to distance/brightness curves, but DM should be giving a MUCH higher mass reading.
Here we have a mini-system that is measured at roughly the mass of the visible stars - if DM is holding it all together the mass calcs should be MUCH higher than the number of visible bodies.
It's like stars in the Milky Way - we give a mass for them based on brightness, distance & effects on nearby bodies, so accurate we can calc the mass of planets around them, yet when we predict their velocity through the galaxy there is no DM component. How can DM affect the rotation curves of the disk unless it is IN the disk & gravitationally interacting with the stars in the disk?
I am unable to make sense of how a cloud of DM outside the galaxy could possibly affect rotation curves from such distances & would expect any such effect would show tighter correlation to the outer stars of the disk, yet the opposite is the case.
Dark matter has NOT been proven to be a thing yet!
Stop messing with the ball earthers you know they cant explain EVERYthing.
Yet another interesting co-mover group that can be, at least substantially, credited to our wonderful little satellite. "[W]e confirm the reality of Ursa Major III/UNIONS 1 with Keck II/DEIMOS follow-up spectroscopy and identify 11 radial velocity members, eight of which have full astrometric data from Gaia and are co-moving based on their proper motions."
3:39. That moving, white starfield murdered the video compression, turning Anton into a potato until it was over ;). Thanks for the video about this surprising object.
Try setting the resolution manually: You get visibly better image quality on 720p manual than 720p auto, for instance, & the same goes for other resolutions. Multi-resolution streams aren't as efficient as single-res
It's rich aliens that decided to retire to the outer neighborhood where things are quieter.
Ģalactic Zoning can turn into a real problem very fast when your quiet gated community suddenly gets reclassified as a Supernova Zone.
It's the sympathy almost no-one has which is nearly as much of a problem as being turned into the tiniest part of a rapidly expanding planetary nebula by something you don't get the time to admit you've zero control over.
Frohe Ostern!
What this really is - an ancient intergalactic civilization that settled around a few planetary systems on which a species of Niblers live. These have been exploited for millions of years for their capability to mine super heavy black matter lumps in the interior of their home planets, which they originally used for heating their homes and for maintaining a strong energy shield for their planets. Then many super rich remnants of an ancient civilization settled in the region and used the Nibler’s mining products for fueling their star ships and more. They have also been able to steer the main stars of that system into some meta-stable orbits around each other to withstand the Milky-way’s tidal gravitational pull. Essentially they solved the n-body problem - by computational methods. They compute control correction forces on the various stars and generate them to keep the star system from falling apart. All is fueled by dark matter from the Nibler mines.
(Disclosure: Some information here was borrowed from Futurama ).
The first probe to reach it will get vaporized after it gets the gate code wrong 3x
Great mystery. Cannot wait to see the resolution!
Thanks for the dose of excitement, Anton!
Another addition to a mightly long list!!
Thanks so much Anton for showing us this study and explaining it's findings so clearly. It's really fascinating, a collection of 20 or so stars, travelling together at the same speed and staying together for 10 billion years despite the effects of huge tidal forces over this incredibly long period of time. What could possibly be 'holding' it together for so long?
Imagine what will happen if one of the theories that explains away dark matter
turns out to be right. It becomes ridiculous when you consider how many of our
observations use something we don't know whether or not it actually exists.
You mean hypotheses not theories.
On the flip-side, “all/most of the above” may prove to be the most correct.🤔
74-78% rotational curvature discrepancy seems far too large in my opinion for just one factor on its own, and could actually be a combination there of.😅
Its not ridiculous at all. Scientists explain their observations through our current best understanding in that particular field and test them through experimentation. Sometimes an experiment or observation challenges that. And sometimes that leads to a complete overhaul in our understanding. But most times it requires a small tweak, a refinement to the theory to explain. But all theories are provisional and may indeed be proven wrong.
To become an accepted theory any dark matter alternative first of all needs to be falsifiable. And second they need to be able to explain our observations better than currently.
Most of these alternatives are varitions of Modified Newtonian Dynamics (MOND). But observations keep on killing them off. You can't blame scientists for not trying the disprove dark matter. But it does seem to be very resiliant.
Any alternative to dark matter has a huge hill to climb to show its a better theory. But that is just how sceince is.
@@chrishartley4553 You keep saying "alternatives" when you should be saying "other explanations" because ALL of the hypotheses of dark matter are just explanations of an anomalous mathematical discrepancy. And your obviously preferred explanation is no more "resilient" than the others, considering that we can detect muons and quarks and yet have never detected a single graviton or axion while they should be all around us, if they exist. (which they don't, IMO) There are many incongruencies in physics and astrophysics. Apparently Andromeda is on a collision course with the Milky Way and yet at the same time it's racing away from us because of the expansion of spacetime. So, which is it? You say observations are killing off MOND hypotheses. But that's not all they're breaking. Phrases like "shouldn't exist" and "thought impossible" have become commonplace in scientific news. This star cluster is just another example of many, just on Anton's channel alone. Technological advances are starting to break all the math and dogma that scientists have been hanging their hats on. (and I'm loving it because dogma is not science) Most have long shunned ideas like Aether while simultaneously embracing that other ethereal medium we know as SpaceTime. And then they pat themselves on the back, and people applaud, because they computer enhanced a picture of a donut of light from four pixels worth of data. It's ludicrous. I think red shift time and distance measurements will be one of the next things to be blown out of the water. There are no strings, extra dimensions, or Hopf fibrations. How many decades have scientists wasted chasing these things when they could have long ago put them on the shelf to be revisited if new evidence emerged and moved on to new ideas or maybe revisiting other shelved ideas for a bit? Science stagnates when you close off avenues of thought.

We enjoy your work so very much. Our window into the complex world of modern science. Thank you. We appreciate you.
As more and more discoveries are made. It would be really amazing to actually categorize Dark Matter. I'd be so thrilled. But, .. every new discovery is a new mystery
I love it 😁
Some globular clusters have BH, that must have formed after an explosion of a supernova, yet some force must have held all together as one object. Amazing.
With all the bad being shoved down our throats all the time, it's nice to have some hope and curiosity thrown at us. Super awesome stuff!
This is how life always felt when I looked up at the stars it’s why I love them so much
Definitely one of the most fascinating objects I've ever heard of. I'm sure that there's a high chance of life existing in the cluster.
Thank you, Anton.
Primordial Galactic Remnant ?
So close too.
what you've described sounds like it could be a "galactic remnant" of an ancient galaxy. say some massive tidal event occurs that strips its arms away leaving only the galactic core. might explain how its maintained stability for such a long time with such a low star count compared to other galaxies that have been observed.
Do you have any idea of how many ä stars a galaxy with arms-like the Milky Way-contains? (It's way, way, waaayyy more than a dozen)
@@majorhumbert676 do you? not sure why you even commented, maybe trolling idk. and yes, theres trillions of stars in our galaxy alone, additionally theres trillions of galaxies. what i'm suggesting is that its possible a massive tidal event could have stripped the arms of said galaxy due to the extreme gravitational effects of such an event would produce. expanding on this, could have been a galactic "near miss" scenario where one or more other galaxies nearly collided with it resulting in its arms being stripped away. the low star population of this particular globular cluster is part of the mystery they are trying to discover, touting dark matter/energy as the reason its able to maintain stability.
Now they have seen this they can start looking for more!
Send Captain Kirk to investigate
Agree… but he’s got to be careful going through the energy ring around our galaxy….
Kirk needs to be assured there are space babes there first.

That's because they're too busy searching Uranus for Klingons.
So cool 😎
Thanks for the video Anton 🎉
Always happy to watch
The more I watch these videos , the more I wish we had a way to investigate these mysteries. Alas however we are but prisoners of gravity. Frail and vulnerable ,we will live out our lives on this rock and just dream of a future when it may be possible to bridge that enormous gap.
Does water sustain life because it’s water or because the physics behind it allow for the formation of life to happen more easily? Does space itself have the same properties as water?
I'm no scientist, but water is the solvent to all the other stuff that makes up our type of life, it allows them to move and mix.
I see space as the opposite, it seems to want to kill life like ours at every opportunity rather than help it thrive.
We have lucky things, like an atmosphere and a magnetic field protecting our water from space. It's why we are here.
Maybe space is the solvent for star construction and galaxy formation, so it is their water in a way lol.
Anyhoo, anymore about space being water and I'm calling out the flat earther. 🤣
Always grateful for your work
Anton never disappoints ❤
3 questions: Is it rotating around a gravitational center? And is there possibly a quiescent black hole at the center of it holding it together? Is it possibly a new arrival to the Milky Way that hasn't had time to be disrupted by the MW's gravitation?
I agree with the other posts really enjoy this daily updates by Anton, I've learned a lot.
Wonderful as always Anton. Thank you. 🧡☺️
What would the milky way look like from this cluster? Should have an amazing view.
Visuals are great! But your explanations are even better.
It could also be just a small number of stars orbiting a small black hole of just a few hundred to a few thousand solar masses. One of the 'missing' mid-size black holes. And with a radius of barely 10 light years, the gravity of such a black hole would be enough to hold the cluster together.
So, it really could be a 'micro-galaxy'.
Anton, I used to live in a neighborhood that had a lot of dark matter. The more that accumulated, the lower the property values became. Listen, take it from me, people might say that dark matter matter's, but don't believe them, it ruins things. Your friend
Thanks! Can’t wait to hear more about this satellite
Something I don't understand is why dark matter would cause it to be resistant to tidal effects. Since dark matter is cold and diffuse, wouldn't the dark matter halo surrounding the cluster be MORE vulnerable to tidal effects? You'd expect the dark matter to extend outside the cluster blanketing it(as with galaxies), but those outer layers should themselves be vulnerable to the larger pull of the milky way?
AI query: "We don't have a clue what this is, can you give us a theory?"
AI: "Sure, Dave, why don't you call it Dark Matter."
ANTON. Thanks for the Information!
The more they find out the more complicated it gets.
Very interesting thank you.
A fascinating episode - thanks to Anton as always.
I think a car park for stars that are being processed for energy collection. Makes about as much sense a chunk of dark energy bound stars.
Thank you
Could there be a small black hole holding this tiny galaxy together?
But then the mass would be concentrated into a small point. I don't know much about this topic, but I can imagine that such a concentration of matter would produce some different results, such as a more unstable system.
Wonderful galaxy stuff, thanks Anton 😍
Hello wonderful Anton this is person 😮😅👍
Informative . Curious intra-galactic objects. Thanks Anton!
A great discovery. Try explaining it with modified gravity. I wish luck to the MOND people.
Thanks, Anton for featuring this.
So dark matter is an invisible force that exists outside our galaxy? Like just empty space or is it everywhere? And is it possible to see gravity waves? If so why can't we see dark matter waves?
The popular theory is that dark matter consists of particles that do not interact with ordinary matter via electromagnetism. Therefore, it wouldn't be visible with light, and it wouldn't collide with itself or ordinary matter, which means it wouldn't collapse into rather small concentrated spinning disks. Since dark matter would only interact with gravity, it would fall into the center of galaxies without slowing down, which means that the concentration of dark matter would be sperically symmetrical, but with a concentration in the center. In the center, the particles from all directions would meet, but they would be travelling very fast.
no, it isn’t a „force”, it is a matter that interacts gravitationally
Thank you
I think they just found the Ghoul Stars from WH 40k:
"The Ghoul Stars, also known as the Ghost Stars, is a mysterious region of space that is a part of the Halo Stars located beyond the furthest reaches of known space... Within this dire realm of Dead Worlds lit by the cold rays of dying suns, tread creatures out of a primal nightmare such as the bat-like humanoids known as the Cythor Fiends, the Togoran Bloodreeks and other creatures so alien as to be seemingly born out of legendary nightmares of Mankind."

I believe this cluster can be reached with a gateway
An ancient mini galaxy, with planets within, of course, a gateway is how the aliens who live there visit earth. 😂
L-gates😅
A dark matter galaxy. Cool idea. The observation could confirm the existence of Dark matter.
Great topic , thank you Anton
Look for objects behind it for tiny gravitational lenses. You might find that the masses create unusual refraction.
This looks like a good place to find aliens. You have a whole bunch of stars of similiar composition of advanced age all relatively close together but free from highly energetic pheonomenon, travelling in what must be a pretty stable configuration.. This looks like an ideal place therefore where a stellar civilisation would have an opportunity to form.
Alternatively it is the remnant of some ancient building block of our galaxy.
Anton, your output has been wild lately! I hope you're OK and just making the most of the increased audience. Take care!! Xx
Thank you Anton ❤
Exciting! Thanks Anton!
Can’t get enough! Thanks Anton!
Awesome videos of stars i look at REGULARLY- THANKS for you work Anton ♾️📡
If we find out it's a dark matter Galaxy that would revolutionize space science.
We should launch an expedition to this realm of 'nowhere'. It seems like a lot of papers are coming from that region.. we might learn a lot!
For science? yes for science. 😂
I heard that The Orion Arm that we are in was a satellite galaxy that was originally from outside our Galaxy. I may have heard it from this channel.
Not entirely. Last major galactic collision was between 8-10 billion years ago, and the average stellar age of stars in milky-way as a whole is actually slightly younger than that.
So a majority of the stars that exist in the milk-way today were actually born here post mergers. Not saying those mergers didn’t contribute greatly in bringing gas and triggering rampant stellar births each time though
Good work man
Endless amazing discoveries and endless amazing videos. Thank you as always Anton.
good coverage of this content and discussion
Thanks anton!
What if ... what we think is dark matter is actually cold and dead objects that have run their course? We can't see them because they do not emit any sort of energy. So they still hold their mass and gravity which could explain why we see the gravitational effects and not any detectable signatures.
If this matter is concentrated enough to form stars, how come we don't see it in older galaxies? If this is too dispersed to form stars, how come they don't obfuscate light as gas clouds?
One theory is that dark matter consists of tiny black holes that formed before the Universe began. Another is that dark matter consists of particles that just do not interact with electromagnetism, hence it's not visible and doesn't collide with itself to concentrate into spinning disks (galaxies)
What if "dark matter" was a gravitational equivalent to quantum locking with superconductors?
fascinating of
❤ ... well and happy Easter
I wonder, Could any of these stars have a Solar System around them?
This was a Reply but thought I would add it to the main thread...

DM and DE are fringe ideas that are full of holes, but we need ideas because we just don't know.
But let me say this. What is gravity? where does this idea of gravity come from? Can I capture some gravity in a jar and study it?
It's all speculation :)
Good stuff Anton
Unions 1 is held together by the power of solidarity.
Maybe it's like a binary star system except that there are a lot more stars, and they're all orbiting each other.
Or maybe what you're looking at is the residue after tidal forces have torn away the rest of the cluster.
Q. Do satellite galaxy structures, such as globular cluster, have to rotate in order to generate gravitational cohesion?
When the gravitation of the milky way is stronger than that of the satellite structure, fragments of the satellite are drawn into the gravity of the galaxy away from the satellite, so the assumption here is that this tiny diffuse group of stars has more than the obvious gravitation potential suggested by visible mass in order to resist that pull and remain as an independent grouping of stars. The inobvious source of gravity is assumed to be dark matter.
Fascinating. Thank you.
Thank you for my predominant source of this type of subject matter.
The speed of sound vs the speed of light . There is a sound barrier which took a long time to discover and IMO this signifies that there may be another speed barrier that can also be broken that we have not discovered yet . The light speed barrier. I would lay you odds there are yet other such barriers we know nothing about.
Thankyou anton for yr work.
Thank you Anton
the reddish clips of gravity simulations at 7:46 reminds me of the beings in the ring in the TV series The Expanse.
It's all about frequency/vibration. All of the stars that have been stripped had the right frequency to blend with our galaxy, whilst the stars that are left just slide past. They also stay reasonably close to each other as other types of stars are not diluting the over all frequency. Also some/many of these "surviver" type stars would've been lost when the cluster was much bigger & contained more diversity
I wonder if someone out there moved the stars to create their own little home galaxy?
Exciting 👍, thanks🤗
