Hi guys, Ricky here

with your Monday news update.

0:00:130:00:16

First up we all know that space

is pretty huge, right?

0:00:160:00:19

But just how big actually is it?

0:00:190:00:23

Yes it's the Big Question.

0:00:230:00:31

Hi, I'm Sarah Bosman and I am

an astrophysicist at UCL.

0:00:400:00:45

I study mostly the early universe.

0:00:450:00:48

Space is really enormous.

0:00:480:00:50

It's so big that it's

kind of hard to imagine.

0:00:500:00:53

The units we use on Earth,

like kilometres or miles,

0:00:530:00:55

don't even make sense to apply

to space because you'll

0:00:550:00:58

just get too many zeros

if you try to think of it that way.

0:00:580:01:01

So astronomers have to come up

with a whole new unit

0:01:010:01:04

to measure distances in space,

which is a light year.

0:01:040:01:06

So for instance, a galaxy

is 100,000 light years

0:01:060:01:10

from one edge to the other.

0:01:100:01:12

from one edge to the other.

0:01:120:01:13

That means if you are travelling

at the speed of light,

0:01:130:01:16

which is the fastest you can ever

go, it will still take you 100,000

0:01:160:01:19

years from one edge to the other.

0:01:190:01:24

And that's only how big one galaxy

is, so if we look outside

0:01:240:01:27

of our galaxy to how many other

galaxies there are, we just study

0:01:270:01:30

small patches of the sky and count

how many there in each small patch.

0:01:300:01:33

And the amount of galaxies we think

are in the universe,

0:01:330:01:36

it's about two trillion galaxies,

which is a ridiculous number.

0:01:360:01:39

So if you took all those

galaxies and split them

0:01:390:01:42

among everyone on Earth,

each person would have about 250

0:01:420:01:45

galaxies all to themselves.

0:01:450:01:46

And that's only the

space we know about.

0:01:460:01:49

Beyond that, there could

be even more space.

0:01:490:01:54

Ok, next up it's the special

orchestra making Norway really cool!

0:01:540:01:58

Watch this!

0:01:580:02:04

There is something pretty

cool about this music.

0:02:040:02:08

It is being played

on instruments made out of ice!

0:02:080:02:13

Brr!

0:02:130:02:15

It is part of an ice

music festival in

0:02:150:02:19

Finse, a mountain village in Norway.

0:02:190:02:22

In winter, it can only be reached

by train and it is very cold

0:02:220:02:26

up there.

0:02:260:02:30

But before they can play,

they have to carve their

0:02:300:02:32

instruments.

0:02:320:02:36

They have made iced

drums, horns, and even a

0:02:360:02:38

didgeridoo.

0:02:380:02:39

This is an iceophone.

0:02:390:02:41

Good sounding ice is the most

difficult part, you cannot just go

0:02:410:02:44

to your freezer, you cannot just go

to the nearest lake.

0:02:440:02:47

It is kind of the sound

of nature, it does not

0:02:470:02:49

sound like anything else

you have ever heard.

0:02:490:02:52

People are really surprised

when they hear it for the

0:02:520:02:53

first time.

0:02:530:02:56

In Finse, the temperature

can drop below -20

0:02:560:02:57

degrees.

0:02:570:02:58

But the colder it is,

the better it is for playing nice.

0:02:580:03:05

It makes them send much clearer.

the better it is for playing nice.

0:03:050:03:07

We don't get to

practice, so the music

0:03:070:03:09

gets made on stage in

front of the audience.

0:03:090:03:11

That is really special.

0:03:110:03:12

People are like, what!

0:03:120:03:13

How is this possible!

0:03:130:03:15

It is almost not possible,

so it is pretty cool that we can do

0:03:150:03:18

it.

0:03:180:03:20

Right, that is it, next time it's

those I am going to make my own

0:03:200:03:23

harp.

0:03:230:03:24

Where is the ice?

0:03:240:03:27

Now many of you might have got

flowers for your mum on mothers

0:03:270:03:30

day, but how about this

for a fancy display?

0:03:300:03:32

Is that Usain

Bolt and the minions?!

0:03:320:03:34

This is the famous San Remo

flower festival in Italy.

0:03:340:03:37

One of the big themes this year

was sport and you could see

0:03:370:03:40

footballers, horse riders and even

racing cars as part of the show.

0:03:400:03:48

Last up, we've all been enjoying the

Winter Olympics and Paralympics -

0:03:480:03:51

but Martin has found a sport

where the people do winter sports,

0:03:510:03:54

with a wee bit of a difference.

0:03:540:04:00

Boys girls, we are in southern

Poland.

0:04:000:04:06

Poland. Ski splash is an event that

takes place in this week town, every

0:04:060:04:12

air. As you can see, it is a real

hoot. 30 participants attempt to ski

0:04:120:04:19

or snowboard across a pool of very

cold water. It combines some good

0:04:190:04:27

old sense of humour, with foam and

sports competition. The best part

0:04:270:04:33

about it is that the comp editors

can dress up in anything they like.

0:04:330:04:40

I know what my next hobby is. Head

online to see why this rescue dog

0:04:400:04:48

stole the show at Crufts.

0:04:480:04:51

That's it from me, Newsround's

back at 7.20 tomorrow.
