12/03/2018 Newsround

Morning, guys.

Martin here with your

Monday Newsorund.

Coming up:

We all love space, but have you ever

wondered how big it is?

We've been finding out.

And we meet the 13-year old ice

skaing world champion.

OK, let's start with

a quick round-up of some

of the day's sports stories.

First, to the Winter Paralympics,

and on the ice, Great Britain's

curling team are leading Sweden

in their latest round robin match.

But it's been bad news for

the british para-snowboarding team -

they have been knocked out

in the qualifying round.

Now, sticking with winter sports,

try not to get too dizzy

when you watch this.

This is 13-year-old

Alexandra Trusova who came first

in the junior figure skating World

Championships.

She already has loads

of world records and is now

the youngest ever World Champ.

Scotland have beaten

Ireland for the first time

in Women's Six Nations history.

Chloe Rollie ran practically

the entire length of the pitch

to score the second of the Scots'

two tries, as they won 15-12.

And staying with Scotland,

there was a cracking Old Firm derby

in the Scottish Premiership -

Josh Windass put Rangers ahead

at Ibrox after just three minutes.

It was 2-2 at half-time before

Celtic snatched victory,

thanks to Odsonne Edouard.

Here on Newsround we love hearing

about you, so we ve travelled

all over the country to hear some

of your amazing stories.

This week we re hearing from Kane,

who found his forever family

when he was adopted.

My birth parents, I mean,

they did love me, but they just

couldn't look after me,

so it's really nice to know

that I now have parents

who can look after me.

Hi, I'm Kane, I'm 15 and I've

found my forever family.

I've always known I've been

adopted and I think that's

really good because,

you know, it's not any secret

that is being kept from me.

It's good to know what's happened

previously, stuff that

I might not have remembered.

In primary school when I told my

friends, a couple of them had been

teasing me about not having parents.

It felt a bit, you know,

not very happy because I guess

I was kind of jealous that other

people had their parents who they'd

lived with all their lives.

But on the other hand,

I was still happy because I did

have a mum and dad.

My brother that I have in my forever

family was also adopted

from a different family into the one

we both share now.

I don't think being adopted

has changed anything.

We still have fun and fights.

What might've happened?

Um...

I wouldn't be having

the life I have now,

which is really good.

It's just kind of shown how

important people are in our lives.

Next, we all know that

space is pretty huge,

but just how big actually is it?

That's what Oscar at Hutton Rudby

Primary School wanted to know.

Here's space expert

Sarah Bosman with the answer.

Hi, I'm Sarah Bosman and I am

an astrophysicist at UCL.

I study mostly the early universe.

Space is really enormous.

Hi, I'm Sarah Bosman and I am

an astrophysicist at UCL.

I study mostly the early universe.

Space is really enormous.

It's so big that it's

kind of hard to imagine.

The units we use on Earth,

like kilometres or miles,

don't even make sense to apply

to space because you'll

just get too many zeros

if you try to think of it that way.

So astronomers have to come up

with a whole new unit

to measure distances in space,

which is a light year.

So for instance, a galaxy

is 100,000 light years

from one edge to the other.

That means if you are travelling

at the speed of light,

which is the fastest you can ever

go, it will still take you 100,000

years from one edge to the other.

And that's only how big one galaxy

is, so if we look outside

of our galaxy to how many other

galaxies there are, we just study

small patches of the sky and count

how many there in each small patch.

And the amount of galaxies we think

are in the universe,

it's about two trillion galaxies,

which is a ridiculous number.

So if you took all those

galaxies and split them

among everyone on Earth,

each person would have about 250

galaxies all to themselves.

And that's only the

space we know about.

Beyond that, there could

be even more space.

Finally, robots that

think for themselves.

Sounds futuristic, but they're

are already here and scientists

are using the technology to teach

the bots to play football?!

Watch this.

Meet the football playing robots.

They're not being operated

by remote control.

These techie sports stars are making

decisions for themselves.

Scientists at the University

of Texas have programmed the robots

to do use artificial intelligence

to have a good old kickabout.

These guys are in training

for a big contest -

the Robot World Cup.

Like this one held in

Germany two years ago.

What a save!

They're able to learn

from their mistakes and improve

their game each time they play.

Rather than turn taking,

everybody's moving at the same time.

If you take too long to think

about what to do when you're

about to pass the ball the opponents

can come and take

the ball away from you.

I think these guys have got what it

takes to make it to the finals,

once they learn to stay

on the feet, that is.

That's it from me for now,

Ricky is back at 4.20pm.

Have a great day at school.

Don't forget to head online

for the rest of the day's stories

and test yourself with our amazing

quiz of the week.

Bye!
