Welcome along, Explorer. Life's pretty boring down here on planet Earth. So let's take a quick

trip around the solar system. Let's find all those secrets. It's a brand new science quest.

Yes, my name is Dan. Around here, we go on awesome adventures right across the universe. We find

out amazing things. We study deadly beasts and we answer your questions.

Now this week, well, we're always travelling through the solar system, but here we'll go right

into the heart of it, seeing what powers our sun. And gravity is pulling all the material of the

sun in. The energy that's being produced is forcing it out and you have a kind of balance.

And so these nuclear reactions go on. The amount of energy that's produced is equivalent to about

100,000 trillion power stations on the earth. Also, you can hear all about a deadly walking hairball and we're exploring a mysterious

frozen world hiding under the ice. Well, we know that the ice is definitely decreasing, the amount of

ice that we have. It is melting as our planet is warming. And some areas

are changing faster than others. So Antarctica, for example, because it's a really big piece of ice,

it changes quite slowly. But in the Alps, we can see those changes, even going back there year and

year, we can see that the glaciers are getting smaller. It's all on the way in a brand new science

quest. Let's all on the way in a brand new science quest.

Let's start with your science in the news. A rare turtle that was taken to the UK after being rescued in Jersey, it's begun the next stage of its rehabilitation at a rescue centre.

It's a loggerhead turtle, brilliantly named crush.

It's been in a huge quarantine tank.

It was brought to Weymouth Sea Life Centre at the start of February.

Now it was found washed up on a beach and apparently lifeless.

So they brought it in, they put it in this tank.

They've kept it there safe and clean,
