Hi, I'm Ricky with the big stories this Tuesday morning.

Paralympic star Ellie Robinson heads back to school.

And from cheers to gears - Matt Le Blanc signs a new deal.

First, to an exciting space discovery -

scientists say they've spotted jets of water

on one of the moons circling the planet Jupiter.

sent back from Nasa's Hubble Space Telescope,

spurting out from the moon's huge ocean under the surface.

Water is important because it means there's a chance

Well, joining me now to talk about this is Dr Sarah Crowther

Thank you for joining us this morning. How exciting is this

discovery to you? It's very interesting and exciting. As you

said, there's lots of water on Europa, but the surface is covered

in a thick layer of ice. We know that water is essential to life.

Nasa work careful to say that they have not found any life there yet,

but these jets of water erupting from under the icy surface might

make it easier to explore the water under their and find out about it.

How will they explore this water? Will they be able to get to it and

take a sample? These images we have seen today and yesterday were taken

with the Hubble space telescope, but it is working at the extremes of its

capability. What these jets mean is that instead of having to land on

the surface and drill through the ice, which could be miles thick, it

might be possible in future to fly a spacecraft or something through the

jets of water, and it can examine the water that way, which would be

easier. Another exciting discovery. Do you think there are aliens in

space? I think there might be somewhere. But I don't know where.

Thank you so much for coming into the studio this morning. Good to see

you again. Thank you. And if you love your space,

go to Newsround online, on how well you know

the Solar System in our quiz! Next, millions of Americans

were up late last night to watch these two people go head

to head in a TV debate. Both Donald Trump

and Hillary Clinton want to become the President of

the United States of America - one of the biggest

jobs in the world. The two candiates spoke about how

they could make the country better, but they also argued

quite a lot too. Donald, I know that you live

in your own reality, I said, "There's a person with

a temperament that got a problem." Well, Americans will vote

for their next president on the 8th of November,

and you can go to Newsround online for more on Hillary Clinton

and Donald Trump. Well, someone who TRUMPed her rivals

at the Rio Paralympics is 15-year-old Ellie Robinson,

who stormed to gold in the pool. It was her first day back

at school yesterday, To the world, she's a Paralympic

champion but, to her friends, she's just Ellie,

the same 15-year-old schoolmate, I've been waiting

to see these guys for ages, and it's so nice being

back, talking to them. We're not even talking

about Rio, to be honest! It's Ellie's first day

back at school, and the reaction

was just a little bit noisy. to the new Paralympic

star of the pool, when they watched back

her record-breaking race. suggests she still can't quite

believe it all happened. It was really strange, because

I remember I kept turning around and checking the scoreboard,

just in case I'd read it wrong, because I didn't want

to be like, "Yeah!" And then like,

"Oh, no, I got silver." Well, it doesn't mean any more

than just having one of my best friends

back at school, someone to talk to. We're all really proud of Ellie

and what she's done. It's quite nice seeing

everyone come back together, It's like kind of united us,

and it's really nice. So special assembly over,

time for an extra special cake. but today was about celebrations,

not exams, and her mates all seem

to have perfected the Ellie pose. Tottenham and Leicester

them going for victory tonight. We respect them a lot,

but we will try to win. Also Porto will try to win

with their different style, And just before we go we've got
