Happy Saturday, everyone!

Leah here today, with Newsround live on CBBC.

Coming up:

Amazing explosions at sea.

And what happens when Stormtroopers go surfing.

But first, straight to some Davis Cup action

because Andy Murray and his brother Jamie are just minutes away

from facing Belgium in the doubles.

The pair will aim to put Britain 2-1 up in the best-of-five tie

and Andy's feeling pretty confident about the competition.

The doubles in Davis cup is always tough, never

easy, just because of the way that doubles is played and can be...you

know...

So, I believe we can win the tie.

But what is it like being part of one

of tennis's most famous families?

We sent some of your questions to the brothers.

These questions are from Fox Primary School.

This one is from Leonardo.

My favourite part of being a tennis player is getting

to play high-level sport.

Getting to travel the world,

playing against the best players in the world, in some of

the biggest stadiums in the world.

For me, that's what's exciting, that's what gets me out of bed

in the morning.

This is from Scarlett.

We don't really compete against each other,

because I'm playing singles and when I do play doubles, hopefully I'm

always on the same side of the net as Jamie, so we don't really

compete with each other any more.

This is from Jack and Leah.

About 800 professional matches. In my career and in singles,

I've won about 550 of them, so far.

This one is from Aaron.

Weird. It's really weird.

I wouldn't recommend it, really.

Cos the first time we really had to do it

in a professional level,

I just tried to focus on the ball, and not look at who was

down the other end of the court, because it was a bit awkward.

Intimidating? Intimidating, perhaps.

Awkward, more likely.

THEY LAUGH

Forget Black Friday, Nasa have been celebrating Black Hole Friday!

The space agency was busy sharing lots of images and videos

of black holes on social media.

They say that a black hole is a place in space where the pull

of gravity is so strong that it starts to drag things nearby towards

it and into it.

This video is extra special.

It shows two black holes merging in to one in an event which Nasa

describes as a "death spiral."

Star Wars Stormtroopers have been spotted surfing the River Severn.

The soldiers of the Galactic Empire took a break from life on the

Death Star to ride the waves in a drizzly Gloucestershire.

The area of the River Severn they were surfing is popular with surfers

because waves surge up the estuary caused by the incoming tide.

It looks like Japan will start hunting whales

in the Antarctic again.

The country had stopped whaling for more than a year

after an international court told them not to.

But now the decision to start again has angered governments and

environmentalists across the world.

Four ships leave the port in Japan, to search for whales.

Last year the country was told to stop whaling in the Antarctic by

the International Court of Justice.

Despite the orders, Japan are making plans to hunt and kill whales there.

Japan say they hunt whales to find out more about them for scientific

research, but environmental campaigners believe they're being

hunted for their meat.

Many people in Japan like to eat whale - it's been a tradition

for hundreds of years and people who sell it can make lots of money.

The country's decision has angered governments around the world,

who say you do not need to kill whales to learn about them.

But right now that's not enough to make Japan change its mind.

It's time to get festive now.

With less than a month to Christmas, how long until the tree goes up

at your house?

Well, the US President's wife, Michelle Obama,

welcomed this year's White House Christmas tree, which was delivered

by a horse-drawn carriage.

The First Lady was joined by White House dogs Bo and Sunny.

Keeping with the winter theme, if you love ice skating then you

might like the look of this:

This ice rink opened on Friday in Moscow and it is pretty big -

20,000 square metres, in fact.

Organisers say it's the largest rink in the world.

It opened with performances by more than 150 actors and Olympic

skating champions.

Now, out to sea where a Royal Navy bomb disposal team carried out

a controlled explosion on a World War II mine off the Isle of Wight.

The explosion created a plume of water about 300 metres high.

It was towed out to sea to be detonated.

It's thought the mine was dropped from a German

aircraft more than 70 years ago.

And just enough time for not one but two panda stories.

First these twin giant panda cubs, who were born

at Toronto Zoo six weeks ago, are doing brilliantly after there

was concern about their weight.

They're now enjoying a diet of bamboo and milk.

And the world's second oldest panda has celebrated her 35th birthday

in China.

Basi, who is over 100 in human years, wore a crown and enjoyed

a specially-made birthday cake.

That's all from me and the Newsround team.

We're back tomorrow.

Have a great day and remember to check out our website.

Bye!
