Watch Stars Move Crazy Fast Around Supermassive Black Hole

At the heart of our galaxy is Sagittarius A*, a supermassive black hole nearly four million times the mass of our sun. Its gravitational effects are quite intense due to its size, and the effects can be detected by looking at the stars in its immediate vicinity. A study, published in August 2020, examined the area surrounding Sagittarius A, looking for the tell-tale signs of stars.

I visited there one time, Tololo as well as Gemini South, with the remarkable Vera Rubin Obervatory's LSST. It was some of the most incredible, and beautiful mountain-scapes I've ever seen, and it was a true shiver down the spine to be that close to, and get visit, these magnificent telescopes, many of whose discoveries we are so familiar with and in awe of. That you got to go there multiple times is a wonderful, and very special, opportunity and experience!! Very cool.

@@skateboardingjesus4006 Yeah, it probably does! We probably don't stand a chance of detecting the Earth-sized ones any time soon, but I bet we could find lower mass stars, even red or brown dwarfs perhaps, by checking for how they shift the orbit of higher mass stars on any close approach. But it'll probably be only a very tiny shift, as anything not in a basically stable orbit would most likely have been either ejected or swallowed up before we started looking!

At 0:35 "the fastest of the bunch, clocking in at 8% the speed of light. At 4:19 "record holder star S29" travelling 8740km/s. That is only 2.9% the speed of light. No mention of the star S4714, which is the star that is travelling the fastest at 8% the speed of light.

[@medexamtoolsdotcom]

Yeah I noticed that too. One thing I've noticed about most of these "science" channels is that they botch things pretty badly and I assume just expect the viewer to not know any better. I don't know why they bother making science videos if they're so sloppy and don't understand what they're talking about and mostly imperfectly copying words others wrote.

[@my3dviews]

@@medexamtoolsdotcom Right. It's possible that S29 was at one time the fastest star detected. Then later a star travelling at 8% of c was discovered. Then made the assumption that the two were one and the same star. They need to fact check their own videos before uploading.

[@Natethesandman1]

It might be that they measured it at 8740 km/s, not at the closest (fastest) point. They could the use conservation of angular momentum to compute the maximum linear velocity when it does reach the closest point.

[@my3dviews]

@@Natethesandman1 No, it is a different star (S4714, not S29) that has been measured at 8% the speed of light. You can look it up for yourself. Here's a quote about it "Sagittarius A * located at a distance of approximately 27,000 light years from us. The mass of the black hole is so large that it allows the star S4714 to accelerate to 8% of the speed of light (about 24,000 kilometers per second) as it passes through the pericenter. During the search, the star S300 was discovered, and it was also possible to observe behind the S29, which approached Sgr A * from 13 billion kilometers, accelerating to 8,740 kilometers per second. End of quote. So, S4714's maximum velocity is 24,000km/s, while S29's maximum velocity is 8740km/s. I can't give the link as it gets deleted by youtube (I tried).

If these stars that orbit so close started as a binary pair, and one was ejected would the star that got free have enough velocity to escape the galaxy? Are there individual stars roaming the intergalactic void? It's almost sad to think about; they would be homeless stars...

[@Cosmoknowledge]

Yes, they become rogue stars, and they can escape the galaxy.

[@TheReaverOfDarkness]

Kapteyn's Star is moving almost at escape velocity and will go well outside of the galaxy before coming back around. It is what's known as a halo star because it is not part of the galactic disk and instead belongs to the galactic halo. Almost all of the fastest stars we see are halo stars moving below escape velocity, but there is nothing stopping stars from getting boosted to even higher speeds. They just spend a lot less time here for us to see them when that happens.

[@kiabtoomlauj6249]

The Barnard Star: Back in 1985, it was ~5.98 light years away from our Sun. By 2005, it was ~5.94 LY's away from our Sun. That's ~11.9B miles per year, traversing ever closer to our Sun's position. If nothing changes its course, by the year 11,700AD, it will be around 3.8 LY from our Sun, making it the closest sun to our own. Currently, Proxima Centauri --- one of the 3 stars of the Alpha Centauri system --- is the closest star to our Sun, at 4.22 LY away.

It depends. If there's a binary star system orbiting close to the supermassive black hole, the gravitational forces can throw one star out of the galaxy and keep the other one in close orbit until the black hole eventually spaghettifies it.

Well, I'm no expert, but I believe, yes, the black hole experiences tugging, but at a so meaningless scale, that it doesn't matter. Imagine a thin thread, and you and an ant are pulling in opposite directions. It's not that the force exerted by the ant is null, it's a fraction of what an human can do. By the way, there are multiple stars near the black hole. While each of them does pull, statistically, they tend to cancel eachover. Instead of having a body (the black hole) clearly oscillating like Pluton and Charon, it's "slightly vibrating" in a erratic way, thus, if you measure the displacents in millimeters (or microns), which would be nothing compared to the size of the thing. That's just a guess, there is no computation nor facts as a basis, a humanly understandable comparison would be Saturn or Jupiter, and their moons.

I suppose this star will also suffer some time dilation. So we might observe it's orbit being skewed in spacetime. Also, the plane of those orbits are not perpendicular to our line of sight. Putting those together, you got some horrible calculations, to define those orbits, not to mention red shift so close to a smbh. Pretty impressive, if they have done those correctly.

Cannot be seen directly in infrared or anything. They only emit the "Hawking radiation" which is very tiny, much too tiny to be seen. Sometimes some matter that gets too close, most of it falls in, but some of it bounces back almost from the brink... you can see that as "jets", so you can see them originating in some empty space, that is where the black hole is. But "our" black hole does not currently have jets. You can also observe, the objects such as stars, that would normally be "behind" the black hole, but because the light cannot go near the black hole, some light from them, will bend around it and you can see the star deformed. Again, that's how you know there is a black hole in between.

[@Cosmoknowledge]

The reason why we see objects in space is either because they emit light, or they reflect it. Black holes don't do either. That's why we can't see them. We can only see the area around them, the gas and dust (accretion disk) orbiting around it.

The beautiful and intelligent British accent might be the reason for your pronunciation. Just thought I might mention it in case it is of any interest. Thank you for sharing this wonderful video. It was very interesting.

Oh, thank you so much for appreciating it. And thanks for the correction. Happy Holidays! ✌

[@jamesmartello1]

@@Cosmoknowledge OH, please don't take it like a correction. I certainly didn't mean it that way at all. It is something I have been corrected for and didn't want someone to say something judgy. In my opinion your beautiful accent makes everything sound lovely and correct. I hope you are having a wonderful holiday season and that 2022 will be even better. Again, my apologies that I said things indelicately or in any way offensive.

A supermassive blackhole and the stars in its vicinity are like when we stir a liquid in our cup. The closer to the middle, the faster the "objects" move. Massive objects like stars moving at the intensely high speed like that is so terrifying to imagine! 🤯😱

Imagine planets orbiting these stars moving around the black hole at the center of our galaxy.

[@Jackie-wn5hx]

Every decade or so, they'll have the best view in the galaxy. Sgr A* and its accretion disk probably looks like as bright as the sun does to us.

[@colinbrown3170]

Will the orbits decay enough that Sagittarius will swallow those stars or they will collide?

[@Cosmoknowledge]

Eventually, probably.

[@jnhrtmn]

I cannot look at rocks on the bottom of the swimming pool and act like it's a black hole. Watch the one star jump an inch to the left instantly while the others don't. It could be a condition of space bending light and creating that entire scene. That's not a theory, because they don't want it to be. It's people, none of which are responsible for what they think. They are just "following" what they were told. Even the black hole images were drawn by creatively calibrating the image until it looked the way they wanted it to look. Man is devolving in intelligence. When you actually question things, they tend to fall apart.

[@mlpadha303]

From such a big distance, if the stars are moving at the speed you have portrayed, it is amazing indeed. But where is the proof of this speed.

It appears that inwardly spiralling stars approach the black hole in an equatorial plane even though the galaxy is a three dimensional structure. Why?

[@nodnarb54]

If time dilation exists then how is it that stars move as fast around black holes? Do objects orbiting black holes fail to move as fast as it should?

[@rotten-Z]

There is an error in the black hole animation. You have an accretion disk rotating simultaneously in opposite directions

[@dsb9574]

Does the gravity of the stars circling around the black hole effect each other? Or does the gravity of the black hole over powers the stars gravity?

[@my3dviews]

The gravity of each star has a small effect on each other, but it is proportional to the mass of each object. Since the mass of the black hole is about 4 million solar masses, each star has only a very small influence on other stars. It also depends on the distances between the stars at a given time.

Sorry, but what's the matter with superspeed close to the Event Horizon of a Black Hole? The formulas tells that the closer to it, the slower the time. And, as fomulas says, any matter will reach the Event Horizon at an infinite time.

When the video mentioned that the newly discovered stars had been given the names S4711 - S4715, I had a feeling there must have been scientists from Cologne involved. Simply hilarious.

[@Levon9404]

Gravitational force is so powerful from black hole even very large stars couldn't scape from black hole. Over vast gravitational force covers very large area. All stars captured by black hole are big enough and they have enough energy reserves not to be destroyed by black hole. The largest stars they don't move too far from black, small stars moves tremendously fast, they approach with high speed the same way they get forced out. If scientists keep following that black hole slowly number of stars will disappeared certain period of time, perhaps that may never happens in life time. Eventually number of stars will decrease next two hundred years even though stars have more dense gravitational force, but black hole will forced them to burn faster all their energy density to distraction.

[@orlandovazquez9662]

This stuff is incredible! A teaspoon of Neutron star matter would equal the same mass as Mt. Everest! Black holes are born when a Neutron star burns all it's elements until it reaches iron(Fe),then collapses and takes Spacetime with it warping gravity. Laws of physics change drastically at this point and no one knows what's on the other side. I love this stuff! Go James Webb!!!💫🪐☄️✨🚀

When there is areas in space with a ultra massive amount of stars, "black holes," which (neither a color, nor a pit, ) is a inconceivable compressions 3D storm, could get so overwhelmed, that a formation would create whats called, a Galaxy. Thus making an infinate conjure of element expansion in space appear very "small waorld." Because mass of matter, has an infinate polarity among the deep limitless space. Example. If two elements just apeared, then travel very fast in head to head direction, but of a two way crossing each other, in adjacent parallel lines, they would eventually maneuver back, in a time acale, just under, *eternity* , by gravity, in a parabolic path shape symbole, called *Infinity*

2:55 time distortion? Time is slower so everything is too therefore gravity does the job by only applying necessary force when collisions is about to happen therefore no collision because time is slow = more time to correct gravitational mistakes? thats why its a pitch-perfect circle Lets say you're driving a car and you slow down, you can see where you're going because you know when youre about to turn, you took the time for it The same goes with time distortion amd gravity, gravity is our eyes and time is time ? Its difficult to explain because english is not my first language Dans le fond la distortion du temps fais en sorte que tout rentre dans lordre car la graviter ne fonctione que sur une loi et cest le temps alors quand le temps est ralentie la loi sapplique tres tranquillement alors ya moins une grande marge derreur
