All language subtitles for How the Universe Works s07e05 Secret World of Nebulas.eng

Through our galaxy, there is a pull
Amazing gas and dust

Seals

Contains the secrets of the circle of cosmic life

The birth and death of stars, planets and humans

Those things are the cradle of creation

You have a close relationship with the feasts
You are the vows of life

The story of our solar system begins with the nebula

If you want to build a solar system, you will need a nebula

Look around you, all you see
Everywhere was a day inside a mist

Scientists are now raising the curtain

They open our eyes in front of the extension
The true expanses of our universe

They solve the mysteries of these creation engines

There are mysteries hiding within them that we did not even imagine

How the universe works

"The Secret World of Sessions"

Milky Way, full spiral galaxy
With areas of gas and dust called the embankments

Everyone has their preferences

I love the horse head nebula, looks great

I have always been fascinated by the mist of the cat's eye

My favorite nebula is the mighty nebula

Maybe the mighty nebula
The best place to understand the emergence of stars

It is here in our art

The mighty nebula is one of the most famous of the dams
You can go out at night and see your eyes

Man kept watching that patch
Blurred from heaven for centuries

The civilization of Maya in Central America is the fire of creation

The Mayans were more right than they knew

Almost every part can be seen from
The life cycle of stars in the nebula

We can not understand the life cycle of stars

Without understanding the life cycle of the dams

They are intertwined

The mighty nebula has everything, from massive stars
On the brink of death to a gas-guzzling birth star

You can see the thin threads of materials, curtains
Which enveloped the fledgling stars

The columns hit each other and Tron
Nogoma makes its way through gas withdrawal

, You see this hive
Frenetic activity, working before us

In 2018, using new data, it is manufactured
NASA envisioned a stunning outline of the depths of the mighty

We have for the first time in history tools
Fit to explore the hearts of those embellishments

It was beautiful when starting out but we have now
Clearer images to appreciate the greatness of this structure

In the heart of the mighty are clusters of young stars

Burst charged particles and solar wind

To open a gap in the middle to make a window inside

We see the structures in their origin
We can see the processes happening before our eyes

The intense starlight of the clusters activates
The gas next to it is blue and blue

The pink comes from the emitted light
Of hydrogen atoms in the nebula

Glows like gas in neon lights

Blue comes from the light emitted by the stars
New warm and reflective dust particles

Those new hot stars illuminate the mighty nebula

But she was born basically in the dark

There is a distinctive type of embellishments
The dark nebula is called

It becomes so basically when
Dust concentrations are larger

Thick dust clouds are obscured
The visible light of the stars behind them

To make shaded shapes such as the horse head nebula

This mist is very large and dense and has
A mass enough to make thirty stars the size of our sun

Astronomers can now stare inside

We have only recently been able to start doing so

Thanks to detectors
Seeing infrared light

Infrared light allows us to see through
Dust the nebula and see what happens in the interior

Humans can not see the light below
Red but we can sensor it as heat

The detectors tell us that dark clouds are formed
The stars are hundreds of degrees Fahrenheit below zero

But in the basement with hot basins

If you look at infrared light

You'll see amazing fingerprints and gradients
Amazing heat, a sign that new stars are born

Parts of the material are lumped under gravity

When gravity increases gravity

It attracts more gas to grow in size

It becomes larger, denser and more hot

Eventually the pressure and heat increase
Enough at the center of this thing

The fusion fuse ignites

The star is born

One hundred billion stars
Which constitute our galaxy

The latest star production lines
It goes back to the dawn of time

And to the first nebula

If we want to reveal the history of the Milky Way
We will start from the beginning, from the Big Bang

13,8 billion years ago

Life in the universe has died

It was initially pure energy

But for more than 300,000 years, that has cooled
Energy to hydrogen gas and helium

The entire universe was then one huge cloud

The basic ingredients of our universe have spread exponentially
The universe, so the universe began as a single giant

Over time, the primitive nebula began
Collapsed and splintered into small parts

These areas have become high
Density even collapsed to tablets

The gas cylinders are very hot in their hearts

The first stars caught

Started with pure hydrogen

But when you get older
I made the other heavier items

Stars are new elements, that's their function

The definition of the star is that in its heart, it merges
Hydrogen atoms to helium and releases energy

But most of these simple first stars were
Giant giant stars do not live long

She burned all her excess
Of hydrogen at super speed

They burned themselves
And died a few million years later

She died with a bang

Explosion issued more elements
Complicated to the initial nebula

After the formation of the first generation of stars

There was a huge resurgence of new elements

Which formed and spread across the universe

To be able to form the second generation of stars

When the second generation of stars lived and died

It added more components to the cosmic mix

The next generation of stars
Merge more elements and explode and die

Its elements are being disseminated to the new generation of
The embellishments to be the new generation of stars

Each generation has more elements
In the periodic table of its predecessor

After the Big Bang 300 million
General Our Milky Way galaxy was formed

Galaxies formed like the Milky Way
From the initial Hungarian nebula

A giant gas cloud collapsed and formed our galaxy

There is a rich cosmic music

Play between stars and endings

We now know that we are part of that grandeur

In the end our sun was born rich in elements

We believe that our sun is a third-generation star

There was a mist then a star
A nebula, then a nebula, and our sun

It took ten billion years to form a mix
Cosmic elements rich enough to form planets of life

Carbon, hydrogen and nitrogen
Oxygen, phosphorus and sulfur

These are the main elements of life as we understand them

It must be formed within the stars

These elements formed during the life of the star

But it needs a very violent process to liberate it to the universe

An event that can be clearly seen across
The Universe

The most beautiful embellishments in our galaxy consist
Of extreme violence

Death of massive stars

One of the most beautiful colorful embellishments in our galaxy
They are the remnants of the great explosions

Such as the cancer nebula, the A-chair, and the veil

All formed when a huge star exploded violently

The nebula was a star
About ten times the mass of the sun

This star will crush him
The atoms together form heavier elements

The process produces huge amounts of energy

The big star can
To incorporate heavier and heavier elements

, Until it reaches the iron
Then things get worse

Iron atoms are so large that
Incorporating it needs more energy than it produces

The pulp begins to collapse on
Himself to trigger a catastrophic explosion

He explodes the elements into space

When the star turns to a low
The greatest it tear itself violently

And all elements of the star
To spread for light years

We call it the nebula of the supernova

We now have a nebula full of all
Those exciting chemicals

All of them are lit by the explosion of the supernova

The remnants of the supernova
Glowing glow in different colors

The colors are represented in the mist or fingerprint
Test the DNA of the elements inside it

Each atom has a cloud cover of
The electrons that orbit their nuclei

When electrons change energy levels,
The frequency of light associated with that variable energy

Send to space and contribute to
The wide spectrum of colors we see

We can look at distant plugins and say that
They have lots of hydrogen or helium

Or a little platinum or a lot of oxygen

Colors reveal the elements
Made during the life of the star and his death

But the shape of the mist reveals
What happens after the death of the star

You may think that the explosive star has
Similar to others with the same type of mist

Then you see the crab nebula in its beautiful complex form

All of those brackets
Swirls of gas and dust

Something must be inside

Disappears inside the nebula of cancer
An astral body is called a pulsating star

Stars are a kind of neutron star

A ball of high density material

Born from the death of giant stars

It is the remains of the core of an explosive star

He collapsed and formed a small ball of
Nitrons are a small part of normal matter

She is very hot and she has
Strong magnetic field

This pulse is about thirty times a second

To detonate radiation spread in
Space as a raging cosmic lighthouse

Pulses in the nebula do not release light
But rather releases winds from charged particles

The cloud of gas around it is the nebula of the winds of spring

So take all remaining materials from the potter
The greatest and launched in that extended cloud

The winds of springing through the gas
Ocean to make swirls and the nebulae of the crab nebula

The supernovae create the elements

Spread by the winds through the universe

To be new dams

Socks may be a solar system like our system

Nebula starting point of the solar system configuration

All ingredients, chemicals and gases
And solids that we see in our solar system today

Imagine the main elements
Which is the planet

What happened to bring them together?

How to cloud a gaseous element
To become our planets and sun?

What about the nebula to our solar system?

In the past they were not there
Sun or solar system or human

Just a cloud of gas
The dust is a solar nebula

We are here today because it is billions of years ago
There was a nebula with all the necessary ingredients

Everything we see in our solar system today was a part
From a cloud of gas and dust, our solar nebula

Five billion years ago are being processed
The solar nebula to be our sun

So billions of years ago there was
Our solar nebula is a cloud of gas and dust

It was outstanding but unstable

What upset the balance to turn
Cloud gas to solid particles?

, Something must change inside the nebula
Something that raises stars and planets

This remains a mystery

What is the answer to this five-billion-year-old puzzle?

There are two theories, both of which begin with fossils

Fossils made their way from
The edge of the solar system towards Earth

Our air cover broke through and made its way towards us

Meteorites are important for us to understand and study

Because it capsules time to when
The solar system was basically composed

Mina and Adwa are one of the biggest
Compounds of comets on Earth

Those rocks have pure records
For the early history of the solar system

There was not in the solar system
Something before the origin of those rocks

There was no land or other planets, this is amazing

The first solid objects that originated from
Cloud dust surrounding our newborn star

Contained the asteroids and meteorites that formed at that time
Time on chemical fingerprints of our solar nebula

It contained the oldest elements and solids that condensed
From the cloud of gas and dust when our solar system was formed

I fought together and formed these
The big rock you see here

In 2017, researchers who analyze
Configure a type of solid meteorites

Called Kondrit, they found evidence
About how to configure our solar system

There may be some hard evidence somewhere
Within the chemical composition of those rocks

He tells us exactly what happened
And how our solar system originated

This definitive guide is
A radioactive component called iron-60

It is believed to be only
In the Great Revolutions

If there was a nebula ready to form stars

And next to him came a greater calamity

The great hypocrite will throw all these
Heavy elements of the gas cloud

It will also research the composition of stars
By hitting and compressing this gas

A nearby star explodes into a larger one

The shock wave hits our bosom
Solar system for iron

But the crash is a breakdown
A sudden attraction at the core of the mist

The gas cloud is clogged
Together to become hot and dense

And our sun is born

When the sun arose, there were
A cloud of snakes around the sun

When it was circling the sun, it merged
And clung to each other and grew into those balls

Over the next hundred million years, those balls became
Larger and larger to be asteroids, moons and planets

All the planets in our solar system look different

Some are snow giants and others
Gaseous giants and some rocky bodies

But all came in fact
From the same nebula before the sun

Our planet grew up
With the right combination of elements

Everything, every atom in our bodies
She was formerly Sodema before my sun

The theory of the Great Surgeon
By pushing our strong solar system configuration

But not everyone agrees

Sometimes the biggest arguments come
Among the scientists of the smallest things

Here I speak of small radioactive atoms

In 2017, studies showed containment
Other meteorites have other radioactive imprints

Rare aluminum alloy
The so-called aluminum-26

It is an irregular atom that does not form
Easily in great twists

It must have come from somewhere else

This other place is a rare type of star
Giant by forty to fifty times the mass of our sun

Star Wolf Wright

, The stars may be strange
The largest is very strange

The largest kind of stars that
We saw her as the stars of Wolf Ray

The stars of Wolf Rye burn more powerful than any star to produce
Heavy elements such as aluminum-26 during their short lives

It is huge, hot and shiny

It unleashes tremendous winds

These stellar winds release tons of energy
Materials from the star to the ocean space

To form a bubble structure

Scientists see the process in the nebula
The bubble is 7,000 light years away from Earth

In the middle of the mist there is one
Massive stars with enormous starry winds

High-energy particles, radiation, as the name suggests
It releases a bubble in the huge mist around it

The walls or bubble crust are dense and full of materials

Stellar winds drive more
The more material inside the cortex

So that the substance collapses with an effect
Its attractiveness and condensation into stars

Possibly what we see in the bubble nebula
Is what happened here 4,5 billion years ago

To form the sun and the planets

If our solar system grew up
Inside Bubble Nebula Wolf Ra> 00:

This will explain the abundance of aluminum-26
Located in meteorites

But it was not decided

What we know is that our story has begun
The collapse of the solar nebula

But our star will someday die

Does the sun turn into a mist?
Awesome or darkened dim?

The embellishments will be stars

The stars are the embellishments

The largest stars do so
With violent superpowers

But 99% of the stars are not
Big enough to die exploding

Some burn themselves to death

But other stars can be dams
Beautiful as a misleading ,, Planetary Safes

From afar they look like planets but ghosts of stars

When stars like our sun begin to die,
Swells to what we call red giant stars

When the stars reach the size of the sun
At the end of her life, her heart is getting hotter and hotter

When the heat is hot, the gas expands
Ocean to turn the star into a red giant

It becomes so large that it is no longer stuck
Gravity with its outer layers

The outer layers of that star begin to drift
Away to lose contact with the central core in the middle

And begin to explode into scales and colors and beautiful forms

We call those starving stars with Planetary Feasts

We discovered about three
Thousands of planetary nebulae in our galaxy

Some seem like hourglasses and others
Like a clown or clown or ball or cake

But if they were all ghosts of the same kind
So why this great contrast?

If there was a star alone
Without planets and without anything around it

It will blow its winds in a spherical crust

If you see Sodema like this
It would look like a bubble of soap in space

But only 20% of the embellishments
Planetary form of a bubble full of consistency

Most of them have these exotic forms
They look like two-lobe or two opposite squid

All shapes are different

Experts believe that alien forms to those
Planetary masts may relate to how the star dies

A new research shows the fate of our star

Sadema will be a bright planet
Beautiful or just disappear in the dark?

We believe for the first time that we have the answer

It's a long-standing debate, is it our sun?
Big enough to be an amazing sdema?

It is a strange coincidence that the model appears
We need a specific mass to form a planetary nebula

By chance, the sun is too high

Assume new data
That our sun will die dazzled

When the sun dies, it will expand
To a red giant filling the sky

We got used to our yellow sun
Kind of moving in sight

Imagine a shiny red glowing ball
A huge swell across the horizon instead of the sunrise

The expanding sun swallows Mercury and then Venus

The surface of the earth will be roasted

To turn him into an infamous hell

The bad news is that when
The sun expands like a red giant

, They will capture the Earth's oceans
Life will not endure then on Earth

Like putting your head in the oven and kneading it

It will be a hard time on earth

This may mean the destruction of the planet

We think the sun will grow
To swallow the earth's position now

Instead of sunrise and sunset
We will find ourselves inside the sun

The sun will expose its outer layers
To throw more than half of its mass

To reveal the stellar pulp

When we look at this pulp is called
Then the white dwarf was the size of the earth

It will be very hot, hundreds of thousands of degrees

This white core radiates hot
Ultraviolet light and x-ray

They are impacted by external gas layers
And turning them into ultra-gloss rings

A planetary nebula will last 10,000 years

It is certain that when the sun turns into a planetary nebula

The solar system will look very different
What it is today, will become unfamiliar

The planetary nebula would mean an end
The solar system we know

The sun will eventually die
And dissolve into space again

But then the cycle will begin again

It is not just an end, it is also a beginning

The plug-in will be supplied
Will create a new solar system

When a solar system dies it is born
Another, this cosmic life cycle

The signs always signify change in the universe

Strongly related to the star's birth and death

Some new notes appear
Our favorite soups are dying too

Can be columns
Famous creation dead already?

Inside the depths of Eagle Eagle Nebula
Dense of cool molecular gas

Probably the best known images
In astronomy, pillars of creation

One of the defining images is the pillars of creation

They were pictures that arouse my memory and my emotion

The columns are five light-years wide

They are shaded by nearby star cluster lights

And those stars have not carved the shape of columns

The surfaces of those stars are full of activity
Boiling and constantly releasing particles

Stellar winds at ten thousand miles
At the hour you get caught up in the ocean gas pull

In the end, the surrounding mist dissipates

When the mist disappears, you will live
Pull thicker and denser

But how long?

"When you look at the pictures" Hubble
Beautiful pillars of creation, eagle eagle

You see a scattered blue gas
Around the columns themselves

This is a guide on how to configure columns
And how it will change over time

This blue foggy gas is just a substance
The superheavy evaporates from the same columns

Nearby stars are slowly melting the columns

This is similar to the way it occurs
Factors of erosion here on Earth

Look at the Monemeunt Valley and those rocky columns
Stunning and exotic forms emanating from the earth

These areas are denser than rocks
They were covered by soil and sand

For millions of years, those substances have been crushed
The lighter to reveal the thickest rocks beneath it

That's exactly what happened here

That process is under way

The pillars are constantly evolving

Know that the pillars of creation
A temporary feature in the life of the galaxy

It will not last forever

In fact, over the time since the capture
Hubble Space Telescope Photo We've seen a change

When astronomers compared data
New "Hubble" images since 1995

They discovered an exploding crater from the mist
At a speed of 450 thousand miles per hour

Stretching a hundred billion miles into space

What might be the source of all that energy?

These are associated with the birth of a star

Stars born inside columns make their way
Outside, eat that substance and blow it away

The nascent stars like children flock to candy

Eat up gas then spin out of control

But the stars also have a magnetic field

This magnetic field spins quickly

The material is swept around it and released
To the outside through the plumes of the poles of the star

They are emitters and astral winds
Destroying the columns of creation from the inside out

Even worse, these nascent stars grow
Quickly until you soon reach the end of her violent life

When the stars die they send waves
Shock, high-energy radiation, particles

Great blasts explosions
As such, the columns may be torn completely

Some assume that those columns may
Already destroyed thousands of years ago

The Eagle Nebula is seven thousand years old
So we see it as it was seven thousand years ago

Not as it is now

It is the sad reality of life

The stars that you make are destroyed

, This happens all the time, everything changes
Our favorite famous sodas will not last forever

It seems sad, but so does the universe

It's a temporary situation, it's change

We see the pillars of creation today and will be
Future clusters of stars

But this is the continuous rotation of the gas
Dust to the stars will not last forever

The embellishments across the universe disappear

Is gas out of our galaxy?

A new search appears to be across the universe
The star formation rate falls quickly

Researchers predict that 95% of all
The stars that will exist have already arisen

Until the galaxy is intact
And maintain the star formation

It needs to collect reserves
New constantly ,, Stuff

Gas runs out of our galaxy and so on
I speak with galaxies all over the universe

That cycle will slow down and will one day stop

More gas is trapped in the small stars
The mass that will not explode in a greater velocity

And the big stars that
An explosive die pays gas away

The galaxies throw materials

Great wind turbines and lighters are sent
Continuously streams of gas and particles outside the galaxy

But the stars do not work alone
But cooperate with something bigger

Experts believe that the main culprit falls
At the center of each galaxy ,, The super black hole

In the past, the Milky Way measured the loss of gas

Hundreds of millions of years ago, it was a black hole
The central is super-large and charges some materials

In that process he launched many
Energy, like a lot of energy belching

He fired gas and probably escaped some
It is completely out of the galaxy

Our galaxy today is still the star

But the gas tank needs to be refilled

The galaxies spin with nitrogen
Be the pillars and the stars

It seems we have now come to a refilling station

We discovered a huge cloud space
Of hydrogen heading towards us

That cloud of hydrogen is huge

With a length of ten thousand light years and a width of three thousand

"Cloud scientists call it" Smith

It revolves around our galaxy and hate 27
Million years will hit the disk of our galaxy

Will bring about the vital collision of our galaxy

To reshape the stars strongly

There will be plenty of gas
Million times the mass of the sun

He can form one million suns

But this is just a snack

To maintain star formation
You need a galaxy for continuous food

, Here in the Milky Way galaxy
We are still stars

This is because our galaxy is galactic

It is surrounded by dwarf galaxies
And eat it and steal its gas and dust

We are the product of mergers, merging
Many small galaxies collide

When a new galaxy hits the Milky Way

They bring with it gas and dust
New and the possibility of creating new dams

By eating a variety of foods add the Milky Way
A few billion years of star formation

But our galaxy is always looking for its next meal

Within a few billion years
Her neighbor will be struck by the galaxy of serial women

When the women merge with the trail
Tebbana will provide us with a new quantity of gas

Although this is a tragic accident
It is really a good thing

Because when it happens stars will be born
New inside the Milky Way

This will prolong the life of our galaxy if we thought so

But there are few galaxies
Nearby to eat Milky Way

In the end on the run
Long will run out of nebula gas

When this gas runs out, there will be no new stars

Whatever happens then it will be
Those are the last generations of stars

Without gas to feed, the dams will disappear across the universe

The universe stops

The dams run out and disappear

The last stars will eventually be turned off

From now on, everything will be dark

The dams ,, One of the finest features of the universe

What makes the babe embellishments it
Pretty but more

It is the cradle of creation

The start and end stars
Building upon them planets and life

I think it's amazing to learn about the universe

I think we finally learn about ourselves

It is our instrument of communication with the circle of cosmic life

The parallels match our lives

, It is very beautiful

But it is temporary

It will not last here forever

This is the story of our universe

This is the story of change

So take your day
