Through the years we found out that we are part of the Milky Way Galaxy. The Milky Way is a barred spiral galaxy, about 100,000 light years across. The Milky Way also contains two significant minor arms, as well as two smaller spurs. One of the spurs, known as the Orion Arm, contains the sun and the solar system. The Orion arm is located between two major arms, Perseus and Sagittarius.
There are many facts that make our galaxy interesting. One of them is that our Galaxy does not stand still but it is constantly rotating. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h). Even at this rapid speed, the solar system would take about 230 million years to travel all the way around the Milky Way. What we know for sure about the Milky Way is that contains over 200 billion stars. There is also enough dust and gas to make billions more and More than half the stars found in the Milky Way are older than the 4.5-billion-year-old sun.
What if I told you that we have detected the fastest star? Yes you heard correctly. We know who the fastest star is! Unbelievable huh?

Billions and billions miles away in the center of our galaxy, there is a realm where the things are so bizarre that it is hard even to imagine. While peering deep into the heart of the galaxy, astronomers have found the fastest star ever seen. What we know is that it is close to Sagittarius A*.
But what is Sagittarius A*?
Sagittarius A is a complex radio source located at the centre of the Milky Way Galaxy and belongs to the constellation of Sagittarius. It is known to be of a super massive black hole with millions of times the mass of our own Sun. Being so big, its gravitational effects are extreme and they can be detected by looking at the stars in its immediate vicinity. Orbiting Sagitarrius A* are a handful of stars moving at mind-melting speeds. The black hole has hundreds of stars pulled tightly into its orbit, traveling exceedingly fast from the gravitational boost granted by this close adjacency.
The black hole at the centre of the Milky Way lies at a distance of 26,000 light years from Earth. This happens because of relativity. It might appead to be excessive but in astronomical scale it is nothing. As we look closer they may emerge stars capable of even greater speeds.
It appears motionless, but there are clouds of dust and gas orbiting it, which provides a clue to the nature of the object. Astronomers calculated its mass using Kepler’s laws and measuring the period and semi-major axis of the orbit of a star that came within 17 light hours of the object. They arrived at approximately 4 million solar masses. The only kind of object that can be that massive and have a radius of about 100 astronomical units is a black hole. Astronomers have estimated that it contains 4.31 million solar masses.
The space research communities around the globe have theorized that there are stars orbiting close to the black hole which have been named as 'Squeezars'.

7:35 Time dilation causes the apparent time to be MUCH slower. NO IT DOESN"T not at 8% the speed of light, you'd hardly notice time is going slower. The time dilation multiplier is 1.00321544 for 8% the speed of light. You could carry on a conversation with somebody in non time dilation with little to no notice of time moving slower on the moving object. Time dilation formulae is T(stationary)=T(moving) X 1/sqrt(1-(v/c)^2). Where v=fraction of the speed of light and c = speed of light or 1 for this ratio. So the multiplier would be 1/sqrt(1-(.08/1)^2) or 1/sqrt(1-.0064) or 1/sqrt(.9936) or 1.00321544 Yea, that's right at 8% the speed of light your time dilation multiplier has to go out to the thousands decimal place before it shows up. Its totally uneducated to state speed time dilation causes the time on the moving object to move MUCH slower! Even at 99.95% of the speed of light on the moving object it would still take an apparent day for a month to pass in the non moving frame. Nice, but still a very perceivable amount of time. So even at 99.95% of the speed of light speed time dilation is not going to shrink a thousand light years down to something you can fit into a couple week journey or human life times.
👏👏👏👏
Great info. Thank you
Thanks for the input Douglas! Will check it out and continue to improve
what an excellent comment, thankyou for your insight 👍 however, you have just drawn a little doubt under that film Interstellar, with planets orbiting a black hole fast enough to cause time dilation!
@@mikenewtonninja9379 Thats for your comment. I haven't seen Interstellar, but stories I've read indicate the writers went to a lot of effort to come up with a way to have significant time dilation. There is also time dilation due to gravity which is equal to the speed time dilation of the escape velocity from the gravitational field. Around a black hole the escape velocity would be a lot!
A big deal would be relativistic mass goes up with the same multiple that relativistic time slows down on the moving object. So if time slows by 10 times the relativistic mass is 10 times more than the resting mass and the object has the inertia of an object 10 times more massive. A person's blood would be 10 times more massive to accelerate. Time dilation due to gravity may not effect the relativistic mass of the object, but I really don't know. The big deal is you need to be going about 99.0% the speed of light or be in an orbit with an escape velocity of 99% the speed of light to get a week compressed down to about a day due to time dilation. Orbiting around a black hole you doing a bit of both.
Save your battery and skip the first 5 minutes, it's mostly padding.
Well that's a nice recommendation for people's battery! We do like complete introductions is true, sorry you see them as padding, hope you enjoyed the rest ;) Thanks for watching!
To Insane curiosity, I do share his sentiment although I understand how the jab can hurt. Reality is there are too many UA-camrs filling up space rather than educate. Especially when science related the triteness is unappealing.
Actually, most sources call the supermassive black hole at the center of our galaxy Sagittarius A STAR (that's how that asterisk is pronounced).
Good catch!
We don’t know what the fastest star is. We know this is the fastest star we’ve found.
Interesting perception, true ;)
Oh you...
Thank you, captain fucking obvious! Wouldn't have known had you've not piped up
I know right? And what is the reference point for our solar systems speed?
The past 13 morning I’ve experienced seeing the stars moving across the sky sometimes 2-8 stars moving across the dark morning sky. One morning I noticed a very bright star appeared and moved across the dark sky.
They are growing on me now even tho I wish for more clarity
You can admire the beauty of S4711 and A4714 with a telescope if you have access to the VLT in Chile
Noted, thanks!
I’m sure there are a lot of different things in space that earthlings have yet to discover.
And that's the beauty of it! What's your favorite topic?
Star go vroom 💫
These are beautiful images. This is a splendid morning.
CGI is an amazing thing huh
You sound like a happy high person lol
High on pills huh
You should watch the music video it's going to be a great day
Respect to the cameraman who risked his life going to universe for taking these pictures😉
I find it difficult to believe that a star could stay in orbit at that speed.
If a star can move this fast we can make spaceships that move even faster in future!!!!!
that means in 10 hours 48 mins and 14 secs this STAR “with a mass at least 100 million earths” travels the same distance the earth travels in 365 days and 6 hours... thats moving lol... that is how powerful Sgr A black hole is
Space sized scales shatter the human mind, they’re incomprehensible...Makes ya feel insignificant in the timeline of the universe
And Sag A* is a baby, at 4.3 million solar masses, compared to the black hole in the center of M87, which has a mass of 6.5 BILLION suns. SagA* is only 14.6 million miles in diameter, which is half as wide as the distance between Mercury and the sun. Whereas M87 is so big, around 24 billion miles in diameter, that our entire solar system can easily fit inside. The diameter of our solar system, out to Pluto, is around 7.4 billion miles. So you could fit 3 of our solar systems, side by side, and have room to spare. I wonder what the fastest star is going around that monster.
Thomas Fleig m87 is massive but u could only fit one of our solars systems in it.. if ur numbers r correct “i did not check” and it is 7.4 billion miles to pluto that means the diameter is 14.8 billion miles and thats only to pluto, not the oort cloud... and yes sgr A is small compared to m87 but is still more massive than 95% of galactic center black holes “because the milky way is bigger than 95% of all galaxies” and it is more massive than 99.99% of all other black holes
@@jonathanlindsey463 I been taught the milky way galaxy is at best an avg galaxy, with most elliptical galaxies weighing dozens of times more and some of these places stretch over a million light years across unlike our own Milky Way being 120,000 light years across. These elliptic galaxies dont spiral because of prior collisions to other galaxies scientists believe. Somewhere I heard the biggest galaxies have trillions of stars unlike our Milky Way of a few hundred billion.
matthew king there are huge elliptical galaxies.. but what i said is the milky way is bigger than 95% of all galaxies and it is.. the milky way is the 2nd biggest galaxy in the cluster we live in we call the local group... locally only 3.7% of glaxies are bigger than the milky way, accross the entire observable univers only 5.0% are bigger... this is counting all types of galaxies... what u need to remember is that 90% of all galaxies are dwarf galaxies... i dont know who told u that 120,000 light years diamater is small for a galaxy.. it is not, it is rather massive
Great video about space !
Someone living on a planet orbiting that star would experience extreme time dilation when their orbit brought them closest to the blackhole, in the course of a couple of years of their time, entire civilizations on Earth will have risen and fallen.
17 Light Hours is just a little less than the distance from Earth to one of the Voyager probes (I forgot which) and it gets further away all the time.
Amazing!!!
The fastest star we have found so far!
Don't "ever seen" and "so far" mean the same thing in this case?
It can. But most of the story was this is the fastest star. Only once was it mentioned that it was the fastest we have found so far. I was just stressing the so far. We just can’t see far enough out to the edge of the galaxy to see the fastest stars.
"Squeezars" Alright we really need to get the Creative Writing community into the research labs to help the scientists with these names.. xD So for a real question...we see these stars blazingly fast rotating around the black hole.... but if you were standing on that star (without dying....) would these orbits appear as fast to you?
I guess U wouldn't notice it being so fast, but would be stopping 4U, steady moving 4 slower moving people.. Come back like Interstellar and everyone u know is older
What I’m actually here earlieish?! Finally!! Love your videos, very informative. I watch these with my 9 year old and quiz him on them after , definitely helps while the pandemic and school at home has been happening still🙄
Hi Natasha!! That's a very nice activity to conserve minds Curious! Specially for the young minds, we are happy to be part of it!!
Good one
Glad you enjoyed, thanks for watching!!
It's called Sagittarius A star! Please say the star at the end of it!!!
I don’t get why it has * in it (Star)
It isn’t even a star.
@@Jay-qb9gi In chemistry, chemists will add a * when they write out the chemical formula to specify that an atom is in an excited state. The physicists who proved that Sgr A* is a blackhole named it that to show that it's an exciting discovery
@@Jay-qb9gi blackholes form when a massive stellar object collapse in on itself to create an infinite dense region in space that not even light can escape my guess at some point it was a star!
@@danbrown5840 haven't heard that before but it sounds logical!
William Buckman s4714 star
It would be nice to study stars going around the black hole in M87, which is 6.5 billion solar masses. Stars passing close to the monster should really be moving.
Sagittarius A* is pronounced Sagittarius A star
Good catch! Thanks
Anyone know if the speed of the stara takes time dilation into consideration? An example being we see the star moving at 8 percent the speed of light but it's really moving at 25 percent based on being so close to the black hole.
Thank you appreciate it! 😁
Glad you liked it Christopher, thanks for watching!!
You're very welcome. 😁
Cool!
Relativity question: Do we expect that stars (or other objects) approaching the speed of light to appear dimmer to the observer? The relative rate of nuclear fusion will appear less to us since the star is moving fast, and therefore it will emit less energy, less light into our relationtional frame. Is there a boundary line at which stars become invisible because they are moving too fast to emit energy in a large enough quantity to be seen from earth? What's the story on the slowest galactic object moving object ever recorded?
I wouldn't be surprised if sprematozoid would enter our universe's 'bubble' one day
Content creator: Sinks hours, days, maybe even weeks into producing 12 minute video filled with scientific facts, writing, editing, narration, graphics design, etc to produce an highly factual, and nuanced look at an under discussed and rather interesting subject.
Viewer: Neat.
"Through the years we found out that we are part of the Milky Way Galaxy" - I assume this is supposed to mean we are now/currently part of the milky way galaxy, because (correct me if I'm wrong) I thought it was discovered that our star was originally part of a smaller Galaxy that was absorbed into the Milky Way (someplace I *should* still have a bookmark if not a pdf with its designation) -- and of course pretty soon [like Triangulum?] our galaxy will merge with Andromeda to become part of "Milkdromeda" [I hope we'll come up with a better name by then]...
The Andromeda galaxy is bigger so I'm sure it'll be The Andromeda Way ;)
Bro that star moving about of 8% speed of light that means the star is not a state of speed of light so there’s more 92% to reach the light of speed but the eccentricity was 0.985 so means if it’s more higher than 0.985 the speed will increase that 0.985 is equivalent to 8% of speed of light so if the star is a state of the light speed(100%) the eccentricity will be like 10.985 (100%) full of light speed
the true speed of light is 1,080,000,000 km/h and 671,000,000 mph and 186,000 mi/s and 300,000 km and 30 cm/ns thats the the speed of light at 100%
so let’s talk about 8% speed of light its 86,340,000 km/h and 53,365,000 mi/h 14,902 or 15,000 mi/s and 23,902 or 24,000 km/s and 0.3 cm/ns that’s the speed of light at 8%
km/h = kilometers per hour
km/s =kilometers per second
mi/h = miles per hour
mi/s = miles per second
cm/ns = centimeters per nanosecond
Gotta give major respect to the idiots that usually say crap about the photographer traveling trillions of miles to capture the images. Major respect for understanding that idea is worn out and not talking about it.
At it's closest approach to the black hole, stars like this shed some materials from it's surface and the materials form the accretion disk of the black hole before ultimately falling into it. As the gas spins faster and faster as it gets closer and closer to the event horizon, it heats up and emits x-ray radiation. That is the reason why the Sagittarius A and other black holes at the center of galaxies can be seen using X-ray and radio telescopes. Also, stars that are this close to the massive black holes are doomed to fall into it like it is being slowly eaten away as it goes to it's closest approach.
That much mass moving that fast would plow right through the earth barely even slowing down.
I would assume that any star orbiting the super massive black hole at the center of our galaxy would have been wrenched from it's planets moons and comets eons ago.
It is shining light out it's back end... Thus reaching for the speed of light by reactionary force... Plus it has magnets in front to go fasta (bro tip)
Wasnt there a star orbiting a black hole at half the speed of light? Veritasium talked it in a video about Spinning BH
That star is moving at about 100+ million miles an hour, giving it the title of the fastest star in the Galaxy 🤔
Actually, its less than 100 million mph. Aprox 53.65 million
That star is very fast.
Definitely!! You enjoyed? Thanks for watching!!
How do we know what the arms of our galaxy look like, how did we find this out?
Ok.
Let's say that one of these very fast stars has a planet in the habitable zone. Let's say that planet is the home of intelligent life. My question is, considering how fast the star is travelling (8% the speed of light) am I correct in saying that the Special Theory of Relativity dictates a notable time dilation for the residents of that planet compared to us, such that from our pov time would travel more slowly for them?
I admit I already felt I knew the answer to the question I just wanted to provoke people to think about it in terms of how the Special Theory of Relativity teaches us to think about relativistic time
The speed would slow down time relative a stationary oberver by about 0.3%. Gravitational time dilation by being so close to a black hole would add another 0.3% or in total about 2 days in a year.
@@119beaker Hi. I may be missing something but I don't quite see how being in a stable orbit with a Black Hole would cause time dilation as there is gravitational equilibrium. ie. the Planet is in free-fall around the Black Hole. Rather, it would be the gravity of the planet itself that would impact on the speed of your clock. eg if it was less than Earths 1G then time would go faster, and if it was greater than 1G then time would go slower. This is the very principle that requires the clocks on GPS satellites to be adjusted to stay in sync with clocks on Earth.
In that region of space, there is NO habitable zone around any of the stars. The amount of radiation coming off of Sagitarius A* will sterilize anything nearby. But you are correct, if you were to be moving at 8% of light speed relative to Earth, your time would appear to move more slowly to Earth, while you would see everything around you going faster.
It doesn't have to be around the black hole to see this effect. It can be anywhere in space, as long as you have the relative motion.
@@MrBendybruce It's not about the gravity relative to the black hole, it's the motion of the star relative to the observer. From Earth, they'd appear to move slower, since they are moving so fast. If you were on a planet around that star, you would be moving at the same speed, and would not see any time differences due to speed. It's where the "Relative" in special relativity that comes into play. Also, don't confuse Mass time dilation with speed dilation, it's a separate affect of being closer to a higher mass, thus the GPS example you gave, due to the bending of the spacetime by gravity.
Imagine the tidal forces involved at its closest. The Roche Limit
It’s a great star. Everybody should have one 😳
Star moving with 8 percent speed of light and how much large the angular momentum it has ?
Greetings earthlings. We are already among you.
If we can estimate the size of black holes mass and thus neutron star within it, and we can see the event horizon. Could we theoretically shoot something that slingshots around it and picks up speed of lets say 90 - 99% of the speed of light (refueling it in the meantime since it would be elliptical orbit) and then have it buzz in between the neutron core and event horizon. Thus coming out on the other end with more than the speed of light, at least while it is below the event horizon, and spewing info at us. Remember that that object will have time dilation, thus never actually going above speed limit (speed of light) from it's perspective... The universe around it would just (seem to) move faster, not it... (Thus maybe being in a blackout)
Ok, so it is still safe to travel at 8% speed of light, nice.
Too much of the random starscapes, while looking neat, have nothing to with the details being narrated. It will give some folks the wrong impression that they are looking at what is being spoken about. You should spend more time making realistic diagrams of the things you are speaking of, and keep them in context.
Thanks for the feedback and for watching!
Interesting data. However, the narration is akin to what I heard in elementary school assemblies. All it needed for authenticity was a simulated slippage of the 16mm film in the projector.
I don't understand it. How do you know that the star is moving and not everything else? There's no space grid to compare it to. And compared to it, light still moves at 100% speed, not 92%
If space is fake I wouldn’t feel so bad about death if that makes sense.
Light is not fast time is fast. Our eyes sees fast, black hole or dark is fast
Boy !! 😳😵🤯
The milkyway is now 150,000 - 200,000 lightyears across.
wow! 54,000,000 miles per hour!
...I wanna see S2
There are videos of that star orbiting the black hole, why not show it 🤔

Love the videos and topics... not a fan of the midroll ads in the middle of the vids. Feel that it ruins the atmospheric mood you build up.
Thank you for watching!! We understand the feeling, it's simply how it works nowadays, don't let it ruin the mood ;)
What they think about?
it means that star is moving about 8% speed of light so it’s not the state of the speed of light yet so that means there’s 92% to reach the speed of light but it’s the max limit to happen for the star
But isn’t a star light?
SO2 ... 10%
Space is me
Ok, so 1) sagittarius a is supposed to be a black hole. 2) Black holes have such strong gravity that even light can't escape. 3) light is made of photons. 4) Well, so are microwaves (radio waves). 5) Sagittarius a is a powerful radio source. 6) So, radio waves shouldn't be able to escape either is, sagittarius a should be radio silent. Q. What is sagittarius a really?
X rays come from the accretion disk not the black hole it self and on a side note, have you ever heard of hawking radiation? because particles can indeed be radiated from a blackhole.
@@amartinez97 thanks, so the narrator misspoke when he said radio waves? It's really x-rays?
When I've had a curry, I somehow run at seventeen times the speed of light to the bathroom!!

Are you sure you can see them using a telescope? Nobody owns a giant infrared telescope in their backyard buddy.
rent a shill So who owns a personal giant INFRARED telescope? Pray tell.
@rent a shill We are talking about GIANT INFRARED TELESCOPE not ordinary SPACE telescope. And it's obvious you can't even name one peroson who personally owns a GIANT INFRARED TELESCOPE. lol
@rent a shill How are obsevatories and space angencies PERSONAL? Or owned by only one person in their backyard? It's funny cause your picture is a brilliant Scientist but you don't even understand what I have posted and you just replied to it saying i'm wrong.
I am wondering how much of a redshift or blueshift of the S4714’s light astronomers see as it orbits the black hole moving in a direction away from or towards us?
Excellent work.
This channel is loaded with ads. I know you’re trying to make money but damn yo.

Ok@$.
I'm sorry but there are so many adds I quit watching after a few minutes. So annoying.
Lets everyone press 'dislike' button so they gonna give us better content. They said that :) :)
I like your content but the extra numerous advertisements are definitely a turn off. Idk if you have control of that somehow but geeze its aggravating
Lmfao. Not very informed dude(s), it's called sagittarius a-star (think of the asterix(*) as a star). Don't believe then read and learn 👍 en.wikipedia.org/wiki/Sagittarius_A*
no content.
Is this computer generated voicing? Because it's grammar is terrible.
grammar slips happens all the time
Andy Skiles, so as yours, coz it should have been "because ITS grammar is terrible" not "because IT'S grammar is terrible". lol
It's a Human being
I pressed dislike just because you tried to brute force a response. Give me a dislike button ONLY. SO I CAN BE SAVAGE!!!!!!!
Claims to bring us "facts" in the beginning and goes right into the BigBang-to-BlackHole fairytale religion of the Islamo-Nazi Democraps' 4th Reich zeitgeist. Simply stated, this video dogmatically misinterprets the evidence into NaziScience propaganda, intentionally!
There are no BlackHoles anywhere in this Universe. Not even one. This alleged object even breaks the alleged rules of black holes in that I don't see the expected "gravity lensing". Perhaps, the plasma density of the region is thinner than the wind?
