Afternoon, all - I'm Ricky, today it's all about space.

And how did the stars and galaxies form?

Scientists hope to answer these questions with the world's biggest

It's HQ is here in the UK, but it's being built

For years, humans look to these guys and have wondered what lies beyond

our world. With our eyes we studied the stars and planets and with

curiosity and amazement. Ancient people believed the stars had

special powers and built mystical structure like Stonehenge to study

the movements of the sun and moon. While others learned to use the sky

as a map to navigate over land and sea. But then came one of the most

important inventions in history. The telescope. A simple piece of glass

that makes things far-away appear close. Using optical telescopes we

found craters and mountains on the moon, sports on the sun, and

discovered we are surrounded by other planets in a galaxy called the

Milky Way. But around 80 years ago scientists began to look into the

Kosmos for things arise couldn't see and they invented the radio

telescope. Science belonging to the invisible world. What an optical

telescope does is enhances the view you get from your eyes. What a

telescope does is it increases the size of your pupils to the width of

the telescope to see fainter things and magnifies. And how does a radio

telescope works? What you see with your eye is the rainbow, from red to

Violet, but beyond the rainbow that is a lot of information you'd write

cannot see. There is infrared and radial and ultraviolet and x-rays

and gamma rays, so a radio telescope helps us see the invisible universe.

If humans had radio dishes for eyes we would be able to see through

clouds and as much by Diaz by night, because these telescopes do not see

the stars but instead the gas between the stars that produces

radio waves. And now scientists are building a giant radio telescope,

100 times more powerful than the best in the world. When finished it

will help us explore further than we have ever seen before. Two letters

discover new galaxies and how the universe began and maybe even find

Alien life. This is the Lowell telescope built over 50 years ago,

still one of the most powerful in the world. But the telescope

scientists are working on now could be 100 times more powerful and its

images will be 6000 times sharper. But it won't just be one massive

telescope like this but thousands of smaller dishes and up to 1,000,010

I. It will be built over an area the size of 200 football pitches. We'll

come to the SKA project. The telescopes are being built into main

countries, Australia and South Africa. They will be faster than any

system that exists at the moment. They will be so sensitive, they will

be able to pick up signals from planets tens of light years away.

This is the most exciting science project of this early part of the

century. We are going to use it to look backwards in time to the

beginning of the universe to answer some amazing questions, such as, or

they are the beings as us in universe? If you can imagine these

being part of the lens. The farther apart the art, the sharper the

image. Add up the areas of all of them and that is one really good

one. These dishes will be the eyes of the project. And a computer like

this one will be the brain. All of the information from the dishes has

to go somewhere, like Best supercomputer being built right here

in the UK. This has the power of 1 million home computers. SKA will see

more of the complete picture and good change what we know about our

universe and life as we know it forever. This week I will see where

thousands of dishes are being built and discover how SKA can help us

detect Aliens. This galaxy is one of millions of galaxies. Maybe the

others live somewhere and another solar system! And you tell us what

it is like to be involved in a project like this.
