- How big is our galaxy? This question invites us on a captivating exploration of scale, distance, and the vast stretches of the cosmos that compose the Milky Way. From the familiar craters of the Moon to the distant, swirling arms of our galaxy, we are about to uncover the immensity of space that surrounds us.
Our journey takes us from our own backyard, the solar system, where planets and moons provide a stepping stone to the broader universe. We delve into the essence of distance, measuring the void not just in kilometers or light-years, but in the time it takes light to dance across the cosmos.
As we reach beyond the solar system, past the outer planets and the Kuiper Belt, we find ourselves at the threshold of interstellar space. Here, the scale of our galaxy unfolds, revealing a vast network of stars, nebulae, and dark matter, interconnected in a grand cosmic ballet.
The Milky Way, with its hundred billion stars, becomes a gateway to understanding not just the size of our galaxy, but also our place within this immense universe. Through this video, the distances that seemed so vast are brought into perspective, offering a glimpse into the sheer expanse of our galactic home.
Prepare to be transported on a journey that stretches the limits of imagination, where the enormity of the Milky Way is not just understood but felt. This is not just a voyage through space; it's an expedition into the heart of our galaxy.

What an endlessly mystifying situation we've been born into
The distance is insane and scary to think how small our planet is, and yet we worry about every small thing in our day-to-day life
Instead of worrying about what our life does to the planet and its inhabitants. Even the smallest things.
that's due to terrible governments and media
Makes sense to worry about the things that impact our daily lifes. See nothing odd with that.
@@Andreas1986xyz people worry about the affect but not the cause
It is more amazing and frightening to know there are at least 100 billion of such Galaxies.
👍🏽Thank you for using miles and kilometers. It’s was very considerate of you.
do you know what for us german is really confusing? the term billion.
in germany and in continental europe we use the term billion for one thousand million (the number that americans calls trillion. trillion in usa, uk = billion in germany and europe.)
i dont have problems of understanding, when you use billion with miles.
but when you say 4,5 billion km, i have to guess, whether you are using the us, uk term or the continental europe term.
really confusing :-))
In the US,
- 1,000,000 million
- 1,000,000,000 billion
- 1,000,000,000,000 trillion

In Europe (without UK :-)),
- 1,000,000 million
- 1,000,000,000 milliarde
- 1,000,000,000,000 billion
- 1,000,000,000,000,000 billiarde
- 1,000,000,000,000,000,000 trillion
we use the so called long scale. us and uk are using the short scale.
It's was?

Mind officially blown! This video brilliantly illustrates the mind-boggling distances within our galaxy and beyond. The analogy of compressing the Milky Way to the size of Earth really puts things into perspective. Such a humbling reminder of our place in the universe!
Unimaginably vast but even the galaxy is nothing compared with the Universe itself.

4:25 If we were to take an airplane flight to Neptune in 1544, with passengers like Michelangelo Buonarroti on board (born in 1475, an Italian Renaissance polymath renowned for works such as the Statue of David and the Sistine Chapel ceiling), we would still require approximately 10 years from today to reach our destination.
Beautifully spoken. Thank you.
If you shrank the Milky Way down to the size of North America then our entire solar system would fit on your fingertip.
It’s interesting to think that if Betelgeuse was to go super nova today, it would have actually happened in the mid 1300’s.

Absolutely wonderful video, just Perfectly done and well enjoyed.
Thank you very much!
It's weird because when you see other galaxies in images all the stars seem like they are so cluttered when they are actually light years apart.
The effect of 2D mapping 3D objects. And actually 4D; everything in motion and with these distances, time is significant.
what a fantastic thought exercise that was. fantastic video!! cant wait to watch them all!
Terrific video - gives an idea of the enormous distances involved!
Can suggest me where to find these amazing voice for videos❤❤ literally nailed it in this video🎉🎉
Unbelievable to fathom these lengths and what an awesome video!
The human brain cannot comprehend the vastness of space.
Right!
Whenever life gets you down, Mrs. Brown
And things seem hard or tough
And people are stupid
Obnoxious or daft
And you feel that you've had
Quite enough...
Just remember that you're standing
On a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second
So it's reckoned
The sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at four hundred thousand miles an hour
In the galaxy we call the Milky Way
Our galaxy itself contains a hundred billion stars
It's a hundred thousand light years side to side
It bulges in the middle, sixteen thousand light years thick
But out by us, it's just three thousand light years wide
We're thirty thousand light years from galactic central point
We go 'round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, thats the speed of light, you know
Twelve million miles a minute and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere out in space
'Cause there's bugger all down here on Earth.

Wonderful video ! I too , I want to know about the habitable's planets existing in the galaxy . How many years that , our sun can tourn around the galaxy ?
Great narration 👍
I live for videos like these. Space is just…………..FUN.
Absolute insanity to think we’re in this thing. What the heck is going on lol. In the end can only accept it for what it is and go about my daily life but man…
And then try and consider something as small as a Planck length!! Totally insanity!!
Incredible. I sometimes try to imagine moving at the speed of light, traveling 100,000 years from one point on the outer edge of the Mily way to a point on the opposite side. I give up trying to imagine this in a matter of minutes.
Makes you feel small. Also makes you wonder what exactly is going on and what is the point when things are so vast. It has to be simpler or WAY more complex than we could ever imagine. Also I think black holes are formations of light particles in other universes.
I think BlackHoles are BigBangs of other universes. No, there's no universe inside them. Seek information. The more I go down that rabbit hole, I see them as a gate. Matter can't be denser than neutron stars. Yet there they are.

I LOVE THIS SH*T...However, these videos make my head spin...the vastness of space is incredible, to say the least.
Fantastic narratives.
It is hard to believe the size of our Galaxy,when we look at the stars
in the night sky.
Hope we can travel one day so far
Why your most videos less than 11 minutes. Please make it longer in the future.
Depends on what parts you include. If you include our galaxy's halo, it extends halfway to Andromeda whose own halo btw is currently colliding with ours.

0:54 Is the trajectory (direction of rotation) of the moon correct?
The problem with the speed of light is it's really slow. Like snail pace slow.
If only more people would understand how miniscule we are in the scale of things in this massive universe, Im sure there would be a lot less hatred against each other and more working together to improve things. Unfortunately we have these religious a-holes ruining it all for the rest of us.
Dude, do whatever you want but never ridicule God..
Who ridiculed God?!? Religion is source of all evil; the very first being separation from God. Give the priest your money and he will speak to God for you.
When you calculated those plane flying distances, did you take into account the fact that the plane has to fly in either an arc to reach Neptune where it will be when the plane finally arrives or some crazy straight line that meets Neptune at the shortest distance?
These orbital curves are used because we don't have the propellant to realy fly a spaceship. We push them (uphill) for 10min and then they roll for several years.
An airplane only works under constant propulsion. I therefor assume he used straight lines, from one place to another. Also, the constant speed was mentioned. A space probe constantly looses speed.
The exception to this are ION drives. But they are still very weak.

I thought the consideration of how many stars and thence possible planets that may contain life being a high number of such perhaps suggesting life might be arising in many parts of The Milky Way to say nothing of any other Galaxy, was an apt consideration: We may not be able to apprehend the distances with our minds but the possibility of life flourishing and growing due to the sheer size is an alternative of interest we should consider a lot more closely: It might suggest we pull our socks up on Planet Earth, and consider the value of life on Earth a lot more seriously...
It would have been nice to point out a few more features of the Milky Way eg 3D, Arms and other features with sizes.
when i watch videos like this i am reminded how many uncountable planets humans will never get to explore, these planets will be born, travel their orbits for eons and pass as their star dies...so much left undiscovered.
Great video. The only thing that’s slightly misleading is that Mars is usually about 12-20 light minutes away rather than 3 minutes.
It varies from 3 minutes/13 seconds to 22 minutes/16 seconds.
The video highlights Mars at its closest approach to Earth, roughly 3 light minutes, not the average distance of 12 light minutes.
فيديو رائع
Makes my head want to explode trying to comprehend all this.
So how long would it take to swim that far? I prefer swimming over walking.

Question, at 4.3 billion km neptune the farthest planet is rotating the Sun.. It takes 4 hours for even the sun light to reach Neptune.. So how neptune is still held in the orbit? What prevents it from moving away? Is it the sun that makes it rotate around or is it the Neptune on its own rotating in this orbit without any hold from sun? If Sun is holding Neptune in its orbit, what force from the sun, keeps Neptune around?
Neptune remains in orbit due to the gravitational force exerted by the Sun, which is strong enough to influence Neptune despite the vast distance. This gravitational pull is what keeps Neptune rotating around the Sun, preventing it from drifting away.
It depends entirely on who is measuring it. If we were twice as big , the galaxy would be half the size and vice versa. Size is not an absolute
Milky way, 100,000 ligthyears equal's 946 quadrillion kilometers close to 1quintillion km. impressive distance amazing...
We could also see
Petrol etc the culprits
If we were to put it on a scale where 1mm represents 100, 000,000 miles then our Day-Star ( The Sun ) would be a little under 1mm away from the Earth. The MilkyWay Galaxy would span a distance equal ( on that scale ) to the one which separates the city of London from the city of Chicago. Every milimeter ( in real space between London and Chicago ) representing a distance of 100 million miles.
Sad we know more about a million other galaxies than our own because we will never see it from the outside ! But ya its freaking huge !
Everyone is talking about how huge is the universe but no one is talking about how all the things in the universe are made up of electron, protons, neutrons, quarks. Dont you think guys as universe is infinite, there might be infinite things inside a electron, we are just not capable to reach there... It's just my overthinking, what are your thoughts about it?
Can any tell how many galaxy and how many planets are there in the universe?
The observable universe is estimated to contain 2 trillion galaxies, with an average of billions to trillions of stars each, many hosting multiple planets.
@ScienceTime24 How the hell did space get so massive? It just shows how special life truly is. We here in earth are so lucky.
Makes me sad to know we will never ever know or be able to see even a fraction of the universe!! 😞😕👈🏽
two trillion galaxies ! Wow , I thought it was or used to be around 100 billion , how many stars do the estimate there are ?

This was awesome. I think only real nerds can evem begin to phathom the ridiculous distances of celestial objects in our galaxy. Now, if we start talking about other galaxies and the universe, it almost doesn't seem real.
The galaxy is only 100,000 light years ac across. But it has approximately 200,000,000,000 stars which is 2,000,000 stars per light year and a light year is 6,000,000,000,000,miles which calculates to one star for every 3,000,000 miles. That means there are on average 31 stars in the distance from the Earth to the Sun.
On average 31 stars!
This also means
It is quite Hard to believe that there are on average 8,000,000 times as many stars in a 4 light year distance as there are in the distance from here to the nearest star.. .
Maybe we underestimate the size of this galaxy, or maybe we overestimate the number of stars in it.
Maybe no one has ever thought this over.
100K light years I believe. If you could travel instantaneously one-half the Milky Way from Earth and look back with a really huge telescope - not possible most likely - you would see Neanderthals walking around. (I don’t know offhand how many kilometers a light year is but it must be huge.)
The average life expectancy of is likely only due to high infant mortality, that number likely isn't very accurate.
And they say there is no other life
Who’s they? Most people likely think that with all the planets, stars, galaxies in the universe the likelihood of life is pretty high!

I love science because science is never rude. Science never insults us. Science is only the study of what is. It does not push an agenda. The intent of science is not to descredit you or hurt your feelings. The fact that so many people have no idea of what science has learned tells me more about us than you can imagine.

Super big!
I hope my next life is exploring for earth like worlds in our galaxy; there are billions of earth like worlds to explore in just our galaxy alone with 500-700 billion stars our galaxy is made up of.
It's so big, there's no need to worry about for the time being.
The only thing confusing about these distances is the switching between mediums
i woul dlove if you add 9 potential plannet..
i dont know why but whenever i think of universe i get depressed and feel lonely for few days
Not me. I feel gifted and blessed. Just think! We are the only living things that we know of in this universe. Our earth 🌎.
We are special and should never feel depressed for being alive and getting to experience everything life offers.
It's only as big as a candy bar.
IC 1101 galaxy is approximately 6 million light years end to end
There’s belief that our universe is just one of many universes.
So big,you can't even wrap your friggin' mind around it😅
Now That's big! Makes my "third leg" look tiny in comparison to our galaxy.
and their might be 2 trillion of these galactic monsters!! Infinity forever!!
One Light Year is approximately 6,000,000,000,000 miles!
Relativity. To US these are vast distances. In the grand scheme of things relative to some else, perhaps something beyond the known universe, its actually very small.
Just think of atoms in our bodies. Relative to us, they are very small. We are their universe. You could view the planets and stars as atoms in the universe. And the universe could be something so tiny in a larger unknown entity.
But these are questions i dont believe our species will ever be able to answer. The answers are forever out of our reach, speeding away from us faster than light as the universe expands. Expands into what? The forever unknown.
They say there are more stars in the known universe than grains of sand from "every "beach on earth and every star has at least 2 planets
The galaxy is so big that it takes 70 years at high warp just to get from the Federation to Kazon space.

Look who forgot Uranus.
Unless my math went wrong along the way
Our galaxy is 662.256 quadrillion kilometers across
And that's just the universe we are in. Our universe is probably just part of the local group of trillions of universes.
Our?
many of people do not have their ovn m2 of earth.
And we believe that the number of Galaxies within the visible universe is more like 3 trillion. Additionally, each galaxy probably has about 40 or 50 satellite galaxies. And we believe a large number of galaxies exist that are not visible from where we are, because the light from those galaxies has not gotten here, yet.
WE may eventually figure out how to trave much faster than we can now, but, Traveling faster than a bullet, Voyager will reach the closest star in 70,000 years. It would take Voyager 17,,500,000,000,years to cross the Galaxy. To get to the next spiral galaxy Andromeda it will take Voyager over 4,375,000,000,000,000 years. And Voyager traveling faster than a bullet, can be hit by something as small as a bullet, which can destroy it. If we were somehow able to speed up Voyager,, the faster Voyager travels, the smaller an item that can destroy it.
If you go buy the constant I think our Galaxy is small because everything in our Solar System is small we're not in the center of the universe
For some reason, i dont believe we are in a spiral galaxy..no one has left ours to say how it looks like only imagination and theories...what if we are in a irregulare or a different type of galaxy? Space never stop to amaze me...also if looking through a microscope is looking back in time how do we know the things we are looking at still even exist cus their kight has taken so long to reach us?
We can observe the distance between stars, by observing their luminosity and apparent change in position as earth orbits the sun. This allows us to see which areas of the Milky Way which are more or less dense with stars, this shows that the stars are arranged in a series of dense regions which form the spiral arms of the Milky Way. The distances between the stars are so vast even a human born 100,000 years ago would see basically the same constellations as us today even though the stars have moved billions of miles. Such is the vastness of our galaxy. And you’re right! When we look at stars we’re looking at their past. At least some of the stars you see in the night sky are already dead and we don’t even know yet.
BIG! 75000 light years across what's THAT tell you?
So if the moon spins with earths magnetic field so we should have more eclipse than every 7 yrs i think we live on flat earth
Aargh! There is it again. It drives me crazy. 2:59
This error happens a lot in space videos showing Earth's orbit around the Sun. The error is having the Earth's orientation against the night sky change from one side of the orbit to the other side. The Earth should always have its North Pole pointing toward Polaris. Earth only changes its orientation over periods of thousands of years.
tch I didn't even notice the first time, but yeah that's a huge DERP get a gyroscope guys
If you think you have a grasp of how big the Milky Way is, you’re still way short of that ideal.
