It's Tuesday, Ayshah here, live this morning,

The penguin with a new 3D printed boot.

And the UK's tallest mountain under the sea.

We're starting with a record breaker.

An aircraft powered entirely by the sun has finished its epic

Solar Impulse 2 touched down in Abu Dhabi in the early

The journey involved 17 separate stages around the world.

The final flight from Cairo in Egypt took more than 48 hours.

Well, BBC science correspondent Jonathan Amos has been

following the journey and is here with us now.

Thank you for joining us. How big a deal is this journey? This is the

first time a solar plane has flown all the way around the world, so it

is a big deal. The two pilots take turns to fire this plane, the two

Swiss gentleman. When they first said they wanted to do this, they

went to manufacturers and said, can you build is this plane? They said,

we can't. It sounds crazy. They were refused to be put down and spoke to

people, developers the technology that can give us a plane to fly

through the day and through the night. It gets plenty of sun but it

needs to store the energy. The journey wasn't easy, they had some

problems. They did this huge journey across the western Pacific Ocean,

which took five days and five nights. Imagine being stuck in the

cockpit for that time, you can't get out and go for a walk. When they did

it, they damage their batteries so had to stay in Hawaii the ten months

to fix it. Finally, people will be wondering, will we be flying in a

solar plane any time soon? Can I go to Barcelona for my holidays on it?

You can only fit one person in it. We may see some small planes in the

future with a few passengers, but you will still be going in a jet on

your holiday. Thank you for joining us.

Next, scientists exploring the UK's tallest mountain aren't

packing their hiking gear and walking boots, they're

That's because the biggest mountain is hundreds of metres underwater off

It's called the Hebrides Terrace Seamount, and is 1700 metres tall.

Scientists are using robots to explore the mountain,

and find out more about the wildlife that live around it.

They've found samples of coral which could be thousands of years

old, and say it could be a hot spot for marine life.

It is so exciting to do this type of research. We see the sea floor come

out, and you don't know what you will find. This is the first time

anybody has seen this seamount and the animals, how they live, what

they live on, in between, he lives with them, not really exciting. We

saw some incredible things. -- that's really exciting.

So that got us thinking, where would you like to

Maybe a safari or some ancient ruins?

Let us know where and why online now.

Next up, many children around the world are forced to work -

that means they can't do normal things like playing with their

This happens to thousands of children in Ghana in West Africa,

It's the African country's biggest fishing ground.

About 20,000 children are being forced to work on its waters -

some of them are sent to work by poor families in the hope

But they end up being made to work as fishermen,

and treated like slaves - made to work without pay

Dampson worked in dangerous conditions.

Some of the boys he met were injured or died.

He is now living with his dad and is back at school.

Dampson is slowly rebuilding his life.

If anything in that report has upset, you can go online

where we've got a guide to help you with lots of information there.

And finally, meet Purps the penguin from Connecticut in the USA.

She injured her left foot five years ago.

But now, thanks to school kids and experts at an aquarium,

they've designed a special boot for her - using a 3D printer.

That is all from me, Newsround is back at 4:20pm.
