Our Universe 3D

(NARRATOR READING)

NARRATOR:
From the beginning of mankind,

people have looked up to the stars,

wondering what marvels could

be found out there.

As science and technology developed,

we finally got some answers.

We learned about our

neighbouring planets that

spin around the sun,

just like the Earth.

We found cosmic nebulae

of incredible beauty,

stars exploding into supernovas

and even black holes.

Ls mankind ready for its biggest discovery?

With our instruments,

satellites and spacecraft

becoming more and more advanced,

we are finding more and

more distant planets.

Is there another Earth

in the vast depths of space?

And could there be alien life?

The answers are out

there, in our universe.

Earth. Our beautiful blue planet. Our home.

Seven billion people live here.

By the sea,

on land,

in the mountains

and in vast cities.

We have evolved from cavemen

to the information society.

Science is exploring all aspects of nature,

be it on our planet or beyond it.

Huge archives of data have been created,

providing answers to many questions.

We have come a long way

from the beginning of the space age,

when the first satellites were launched,

and man set foot on the moon.

Our probes have visited all the planets

of our solar system

and delivered a lot of data.

We now have a good understanding of how

our home system in this universe works.

There are eight major planets.

Mercury, which is closest to the sun,

and very barren.

Venus, with her thick atmosphere

and furious volcanoes.

Earth, the only known planet to host life.

And Mars, the Red Planet, a neighbour

that has had a lot of human-made visitors.

Farther out is Jupiter, a giant made of gas,

with over 60 moons.

Saturn, with its mighty ring system.

And, finally, Uranus and Neptune,

the "ice giants".

Beyond them lie huge asteroid fields

and some dwarf planets, like Pluto and Eris.

All these heavenly bodies revolve

around the sun.

It's the centre of our solar system

and also its superpower.

Without the sun,

life on Earth wouldn't be possible at all.

Basically, the sun is a gigantic energy

reactor that produces radiation and light.

In order to be able to look at the sun

with our human eyes,

we need to decrease its luminosity

by 98% first.

We are now looking at the pulsating surface.

The temperature here is

over 3 million degrees Fahrenheit.

The darker areas are the sunspots. They

are plasma craters the size of the Earth,

where temperatures are lower.

The brightest areas, on the other hand,

are solar flares.

The plasma there reaches temperatures

of up to 10 million degrees.

These flares can cause ripples that look

just like ripples on a pond from here,

when in fact the waves are 2 miles high,

and move at hundreds

of thousands of miles per hour.

But the highest temperatures are

found in the very core of the sun,

going up to almost 30 million degrees,

because in here

hydrogen is constantly fused into helium.

Through this process of nuclear fusion,

the sun releases energy

equalling millions of atomic bombs

every second.

A great deal of this energy is

released in the form of photons.

These photons dart around the core

at light speed,

but they collide with matter so often,

that it takes them thousands of years

to finally escape into open space.

From there,

they only need about eight minutes

to cover the 100 million miles to Earth

and arrive here as what we know as sunlight.

But the sun doesn't only supply light.

It's responsible for 99% of the Earth's

energy intake.

In the entire history of mankind,
