Good morning.

I'm Ricky, bringing you Tuesday's top stories coming up.

Incredible photos of a lunar eclipse.

And the hunt is on to find the next Olympic mascot.

First to the World Athletics Championships in London

where there was heartbreak for Great Britain's Laura Muir

in the women's 1500m final.

It looked like she would take the bronze medal

but she was overtaken right at the end, missing out

by just seven hundredths of a second at the finish line.

Gutted.

And there was more bad news for athletes taking part.

The organisers of the competition say a number of competitors,

staying at the same hotel in London, are thought to have

got a stomach bug.

It affected Irish hurdler Thomas Barr and the

Botswanan Isaac Makwala - both were forced to pull out

of their races on Monday.

Now the Olympic and Paralympic Games is nothing

without one of the these.

A mascot.

Well, the hunt is on to find the next face of the Tokyo 2020

Games, as Ricky's been finding out.

Yet there is just over 1000 days to go until the Tokyo Olympic and

Paralympic Games.

That gives this lot just enough time to find a mascot

for the greatest show on Earth.

In 2012, at the London Games, Wenlock

and Mandeville kept the crowds entertained.

During the Games in Rio, Brazil, last year, these

fellas stole the show.

So, how do you go about finding a mascot to represent Tokyo 2020?

Well, a competition in Japan has kicked off, where ordinary

people can design and send in their own creations.

I want mascots with cute smiles.

Mascots are big business in Japan.

Becoming one takes a lot of training, as Newsround's Leah

found out a few years back when we sent her

to a mascot training school.

Guys, it's me.

This is Leah and this is my mascot.

Don't give up your day job, Leah.

The winning designs will be selected by children

across Japan in a big vote.

The winner announced in March next year.

Now take a look at these beautiful shots of the moon.

Last night a stunning lunar eclipse was visible

in many parts of the world.

Eclipses happen when the Earth passes between the sun

and the moon, casting a shadow.

This one could be viewed on several continents,

although many countries could only see part of it.

A second full eclipse will occur on the 21st of August

over North America.

Animal news now.

And the fight against illegal hunting, called poaching.

The British Army are helping park rangers in Gabon, in Africa,

to protect elephants there from poachers,

who are hunting them for their ivory tusks.

Here's Ricky.

These forest elephants are under threat, all because of their tusks.

They live in Gabon, a country on the coast of Africa.

Most of Gabon is covered in rainforest -

stretching for thousands of miles - and most of Africa's forest

elephants live here.

But poachers want their tusks, which are made of

ivory, so they can sell them for lots of money.

It's thought 30,000 elephants have been poached in the

last ten years, that's more than half the elephants in Gabon.

Even though there's a worldwide ban on the sale of ivory,

there's still an illegal trade, and poachers can make

a lot of money from their tusks.

But the British Army hopes it can help

to tackle the problem.

Gabon has a real high density of forest elephants.

That's why it's gotapproaching problem.

Out here, training the Gabonese National Parks

Agency to combat that means the British Army can make

a difference in the fight against the illegal

wildlife trade.

They are training park rangers on how to find

poachers hiding in the forest and help get the evidence they need to

get them sent to prison.

Poaching is a huge problem here but it is hoped

that the training the British Army are giving can

make a big difference.

OK.

Listen up...

Lots of you are still on your summer holidays,

and even though some of you go back to school pretty soon.

We want to know what you've been up to.

The big question is, have you spent too much time

on your smartphones?

Be honest!

Well, the children's commissioner says you guys should limit

the ammount of time you spend on social media.

So head to Newsround online, and let us know what you've been up

to.
