And the Hello and welcome to the naked scientists with me, Grey Jackson. This week is a very

special edition as we dedicate a whole hour to the world's favorite

dwarf planet, Pluto.

But how did it get there in the first place?

What has the New Horizons probe uncovered, and what's beyond Pluto?

I'll be putting the mission under the microscope, talking to some of the leading scientists

from the operation, and taking a trip to the edge of our solar system. the But before we travel out past Mars, Saturn, Jupiter, Neptune and Uranus to Pluto,

we're going to travel back in time, back 4.6 billion years to the dawn of our solar

system when all that existed was a giant ball of dust. It's amazing to think that everything around us started as a few elements

floating around in space, but how do we know that's the case? Well, new solar systems are

forming all around us, all the time, and with the help of a telescope,

astronomers can photograph the drama as it unfolds.

My name is Brendan Owens, and I'm an astronomer here at the World Observatory Greenwich.

What are these beautiful pictures we're seeing right in front of us?

So this is a selection from our yellows and red, very, very rich.

It's kind of amazing and maybe a little disappointing for some people sometimes is that the

color that you see in a lot of the images is what we call false color.

Those filters are corresponding to just particular energies from particular atoms, so iron, carbon, oxygen,

and then you can choose to color them in.

Now just to avoid confusion, we don't go all creative and color them in whatever we want to try and stick to a

palette called the Hubble palette so we all kind of recognize what the different colors are.

So typically in images and the reds and pinks are they can be hydrogen sometimes a different
