Well, ahoy there, explorer. It's time to search through the solar system then. My name's Dan.

Shall we see what's lurking in a brand new science quest? You have stumbled upon the smartest

show in the universe. It's all about brilliant guests, your genius questions, and very unique beasts. Well, this week, did you know,

if you hopped in a car and drove towards Saturn, you wouldn't get there for 16 centuries.

Today, we look at why even our fastest rockets take years to reach there.

It took over six years to get there,

and it used gravitational swingbys of Venus twice and the Earth,

so it had travelled over a billion miles and got it precisely nowhere.

Also, you can hear about a strange friendship under the sea, and if you think life on Earth is crowded,

well, think of this, 94% of all living species are underwater.

How is life distributed in the ocean and roughly how many species live in the ocean.

And I don't think we've got a very good understanding of either of those.

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

Let's start with your science in the news.

And visitors to ZSL London Zoo will soon be able to watch live veterinary procedures inside a state-of-the-art new animal hospital.

It's all thanks to a mystery, 20 million pound donation.

No one knows who gave it to them, but they've put the money to good use

because a viewing gallery will show everything from penguin health checks to ultrasounds on

Ardvarks, even what happens when creatures aren't around any more strange, spooky, but awesome

things like that, things that have never been seen before publicly in the UK.

It's been made possible by the zoo's largest ever gift.

Loads of money for a brilliant cause, very excited to see what's really happening inside an animal hospital.
