0:00:02 > 0:00:05Soon, starlight will scatter through the dark.

0:00:05 > 0:00:08So, let's all look up at Stargazing Park.

0:00:09 > 0:00:12Hello, stargazers.

0:00:12 > 0:00:16Last night, we found out about astronaut Tim Peake's

0:00:16 > 0:00:19exciting mission to the International Space Station.

0:00:19 > 0:00:23We're joining in with Tim's mission, too, aren't we, stargazers?

0:00:23 > 0:00:25- ALL:- Yes!

0:00:25 > 0:00:28We're wearing mission patches, just like Tim's.

0:00:28 > 0:00:32You can download one from the CBeebies website.

0:00:32 > 0:00:36Inside the International Space Station, Tim will be finding out more

0:00:36 > 0:00:42about space, and so can we right now. All we have to do is...

0:00:42 > 0:00:43look up!

0:00:47 > 0:00:51MUSIC: Stargazing by Barrie Bignold

0:00:51 > 0:00:53# When the night falls

0:00:53 > 0:00:58# Maggie helps us see wonders of the stars above us all

0:00:58 > 0:01:03# Turn the lights low, grab a cosy rug, wrap up warm and snug

0:01:03 > 0:01:05# Here we go

0:01:06 > 0:01:09# We're going stargazing

0:01:09 > 0:01:13# Gaze at stars shining bright

0:01:13 > 0:01:16# We're going stargazing

0:01:16 > 0:01:19# Spot a zooming satellite

0:01:19 > 0:01:22# We're going stargazing

0:01:22 > 0:01:26# Glimpse the moon and the planets above

0:01:26 > 0:01:29# We're going stargazing

0:01:29 > 0:01:34# So just look up, look up, look up. #

0:01:47 > 0:01:50Come and join us underneath the stars.

0:01:50 > 0:01:52- Hello, stargazers. - ALL:- Hi, Maggie.

0:01:52 > 0:01:54Are you all wrapped up nice and warm?

0:01:54 > 0:01:56- ALL:- Yes.

0:01:56 > 0:01:59- I've got some gloves. - I've got a blanket.

0:01:59 > 0:02:02It is rather chilly tonight, isn't it Maggie?

0:02:02 > 0:02:05Yes, Chris, that's because there aren't many clouds.

0:02:05 > 0:02:09The clouds act like a big fluffy blanket, keeping the earth warm,

0:02:09 > 0:02:13and when there aren't many clouds, it feels a lot chillier.

0:02:13 > 0:02:17But when we don't have clouds, we can see more stars!

0:02:17 > 0:02:23With not a cloud in sight, we can see the stars shine bright.

0:02:23 > 0:02:25Who else is looking up tonight?

0:02:32 > 0:02:34It's Cat!

0:02:34 > 0:02:38Hi, Chris. Hi, stargazers. We've been wrapped up warm

0:02:38 > 0:02:40- to go stargazing too, haven't we? - ALL:- Yes.

0:02:40 > 0:02:45In fact, we've been wrapped up warm all day because we've been somewhere

0:02:45 > 0:02:48- really chilly. Where have we been? - ALL:- Ice-skating!

0:02:48 > 0:02:52And while we were there, we got a really good view of a star.

0:02:52 > 0:02:55Come back later and find out what we saw.

0:02:55 > 0:02:58Sounds exciting, Cat. See you later!

0:02:58 > 0:03:02Now, have you still got a good view of the stars, stargazers?

0:03:02 > 0:03:04- ALL:- Yes.

0:03:04 > 0:03:05There are lots and lots.

0:03:07 > 0:03:12They're actually like little dots, but they're really, really far away!

0:03:12 > 0:03:15That's right. The stars are really, really far away,

0:03:15 > 0:03:18so they look really tiny from down here on earth.

0:03:18 > 0:03:22In fact, lots of them are even bigger than our sun.

0:03:22 > 0:03:24How are stars made?

0:03:24 > 0:03:26Oh, now that is a good question, Emily.

0:03:26 > 0:03:30Maggie, how are beautiful, gigantic stars actually made?

0:03:30 > 0:03:34Well, I've got a good way of showing you and it will warm you up, too.

0:03:34 > 0:03:36Follow me to the cafe.

0:03:38 > 0:03:43A star is made in a very, very, very cold place.

0:03:43 > 0:03:48It's made in a dark cloud of gas and dust, like this one.

0:03:48 > 0:03:53Let's make our own cloud of dust and gas, and we can be the dust.

0:03:53 > 0:03:56This cloud is enormous!

0:03:56 > 0:03:57Let's spread out!

0:03:59 > 0:04:02Ooh, it's a bit chilly in the cafe tonight!

0:04:02 > 0:04:06- How does everybody else feel? - ALL:- Cold!

0:04:06 > 0:04:09Well, don't worry, you won't be cold for long.

0:04:09 > 0:04:12Bits of dust - start walking towards each other.

0:04:12 > 0:04:17When a star is formed, gravity slowly makes the bits of dust

0:04:17 > 0:04:20and gas move towards each other and stick together.

0:04:20 > 0:04:24So, find another bit of dust, and give it a hug.

0:04:24 > 0:04:27- How do you feel now? - ALL:- Warm!

0:04:27 > 0:04:31Look at these amazing pictures of enormous clumps of gas and dust

0:04:31 > 0:04:34sticking together to make a new star.

0:04:34 > 0:04:38As they stick together, they get warmer and warmer.

0:04:38 > 0:04:41But this takes millions and millions of years.

0:04:41 > 0:04:46But I'm so chilly! I can't stay cold for millions of years!

0:04:46 > 0:04:48Don't worry, Chris. I've got a plan.

0:04:48 > 0:04:52Eventually, all the bits of dust and gas fall together

0:04:52 > 0:04:55to form one giant clump, so...

0:04:55 > 0:04:59- ALL:- Group hug!

0:04:59 > 0:05:03Oh, I am definitely warmer now. How are you feeling, stargazers?

0:05:03 > 0:05:04- ALL:- Warm!

0:05:04 > 0:05:07We're not a spread out cloud of dust and gas any more.

0:05:07 > 0:05:11- We're a tightly packed clump. - All huddled together.

0:05:11 > 0:05:13Let's huddle even tighter.

0:05:13 > 0:05:15Whoa!

0:05:15 > 0:05:19- How do you feel now? - ALL:- Really warm!

0:05:19 > 0:05:23As the clump of dust and gas gets more and more tightly packed,

0:05:23 > 0:05:26it gets hotter and hotter, and then suddenly...

0:05:26 > 0:05:29- ALL:- A star!

0:05:29 > 0:05:32The middle of the clump gets so hot that it sets alight

0:05:32 > 0:05:34and a baby star is born!

0:05:35 > 0:05:42So, a star is made from a ginormous cloud of dust and gas.

0:05:42 > 0:05:48Gravity pulls the dust and gas together into a tightly-packed clump

0:05:48 > 0:05:52until the middle gets so hot, it becomes a...

0:05:52 > 0:05:54- ALL:- ..star!

0:05:57 > 0:06:01Hi, stargazers. When I blast off in a rocket, it will only take me

0:06:01 > 0:06:05a few hours to get to the International Space Station.

0:06:05 > 0:06:08Other spacecraft have been travelling for years and years

0:06:08 > 0:06:10exploring space.

0:06:10 > 0:06:13The Voyager mission has been travelling through space

0:06:13 > 0:06:15for nearly 40 years.

0:06:15 > 0:06:16That's nearly as old as me!

0:06:16 > 0:06:19It's taken pictures of lots of planets

0:06:19 > 0:06:22and taught us lots about our solar system.

0:06:22 > 0:06:25Right now, it's just going out of the solar system.

0:06:25 > 0:06:28But if it were to go to our next nearest star,

0:06:28 > 0:06:32it would take thousands of years to get there.

0:06:32 > 0:06:36Wow, all those stars up there are a long way away, aren't they, Maggie?

0:06:36 > 0:06:40Yes, they are, but there's lots of ways to find out more about them.

0:06:40 > 0:06:43Who'd like to see some more stars being born?

0:06:43 > 0:06:45- ALL:- Me!

0:06:45 > 0:06:49Well, earlier, I sent Robert the robot on a very special mission.

0:06:49 > 0:06:51Robert, over to you.

0:06:52 > 0:06:56Very happy to be of assistance, Maggie. It's Robert the robot here

0:06:56 > 0:06:59and I'm about to meet a very clever space scientist.

0:06:59 > 0:07:02- HE LAUGHS EXCITEDLY - I can't wait! I can't wait!

0:07:02 > 0:07:06I'm going to meet a real life space scientist!

0:07:06 > 0:07:08Hello, Robert.

0:07:08 > 0:07:11Well, hello, Tim. I did not see you there.

0:07:11 > 0:07:14Everybody, this is Tim, and he is a real life space scientist

0:07:14 > 0:07:18and he's very clever, you know. Now, Tim, please could you show us

0:07:18 > 0:07:20how stars are born.

0:07:20 > 0:07:25- I certainly can, and we're going to do that just over here.- Oh, oh.

0:07:25 > 0:07:28- ROBERT GASPS - Wow!

0:07:28 > 0:07:31- So, what is all this?- This is the desk from which we control

0:07:31 > 0:07:33that giant telescope out there.

0:07:33 > 0:07:36- HE GASPS - And it's with that giant telescope,

0:07:36 > 0:07:40- that we can actually see stars being born.- We can, yeah.

0:07:40 > 0:07:44- Have you heard of the constellation of Orion?- Oh, yes, I have, yes.

0:07:44 > 0:07:47Orion looks like a man strolling through the night sky.

0:07:47 > 0:07:51Yeah, and if you look below the belt of Orion, you can see

0:07:51 > 0:07:54- the Orion Nebula.- Oh, yes. - This is a photograph of it.

0:07:54 > 0:07:58It's a cloud of gas and dust. And, if we use this telescope

0:07:58 > 0:08:01to zoom right into the middle of that cloud of dust, what we see

0:08:01 > 0:08:06- are these young stars. These stars have just been born.- So, those

0:08:06 > 0:08:10young stars are in the middle of that massive cloud of gas and dust?

0:08:10 > 0:08:14They've been made from the dust, all sticking together, to make the star.

0:08:14 > 0:08:18Hold your radio waves. So, are you trying to tell me

0:08:18 > 0:08:22that stars are born out of gas and, my old foe, dust?

0:08:22 > 0:08:26They definitely are. It's not just the stars. Around the stars,

0:08:26 > 0:08:30what's left behind after the star's been made, is a disc of dust

0:08:30 > 0:08:33and inside that the planets are being made.

0:08:33 > 0:08:34HE GASPS

0:08:34 > 0:08:38So, let me get this straight, the very planet that we are stood on now

0:08:38 > 0:08:42- is actually formed out of dust? - It certainly is.

0:08:42 > 0:08:44Well, I never knew dust could be so useful.

0:08:44 > 0:08:47- HE GASPS - Tim, if I took my duster and shook

0:08:47 > 0:08:50it out into space, do you think we could make a new star?

0:08:50 > 0:08:53You'd need a lot more dust than that, Robert.

0:08:53 > 0:08:56Oh, Timothy, you don't know me at all. I know dusting.

0:08:56 > 0:08:58Come here, let me show you.

0:09:00 > 0:09:05So, when a star is made, the leftover dust spins around that star

0:09:05 > 0:09:07and makes...

0:09:07 > 0:09:09- ALL:- ..planets!

0:09:09 > 0:09:12I wonder what Kat and her stargazers found out

0:09:12 > 0:09:15when they took a closer look at a star.

0:09:19 > 0:09:21Ice-skaters!

0:09:21 > 0:09:25Well, yes! And they're going to show us what happens when a star is born.

0:09:25 > 0:09:28- Who can remember what stars are made from?- ALL:- Dust!

0:09:28 > 0:09:32Yes, they are. Oh, the bits of dust are on the move!

0:09:35 > 0:09:40- They look like a giant clump of dust.- You're right.

0:09:40 > 0:09:43And they're getting hotter and hotter!

0:09:46 > 0:09:49- It's a star.- Yes, it is a star!

0:09:54 > 0:09:56What's happening to the rest of the dust?

0:09:56 > 0:09:59It's spinning around the star.

0:10:09 > 0:10:11Look, it's a planet!

0:10:11 > 0:10:15That planet looks like it's got something orbiting it.

0:10:15 > 0:10:17- What could it be? - A moon.

0:10:28 > 0:10:30A comet!

0:10:30 > 0:10:32Look at its icy tail.

0:10:32 > 0:10:35It looks like it's zooming through space.

0:10:37 > 0:10:41Can you think of anything else that zooms through space?

0:10:41 > 0:10:43Asteroids!

0:10:43 > 0:10:45Giant rocks zooming through space.

0:10:45 > 0:10:46WHOOSH

0:10:52 > 0:10:56Who knows what smaller bits of rock in space are called?

0:10:56 > 0:10:57Meteoroids.

0:10:57 > 0:11:01I think I know some stargazers who would make perfect meteoroids.

0:11:01 > 0:11:04- What do you reckon, stargazers? - ALL:- Yeah!

0:11:04 > 0:11:05Come on!

0:11:09 > 0:11:13'A baby star shines in the dark of space.

0:11:15 > 0:11:19'And the leftover dust doesn't go to waste.

0:11:23 > 0:11:26'It makes planets and moons,

0:11:26 > 0:11:29'and other things too,

0:11:29 > 0:11:30'like comets...

0:11:30 > 0:11:33- 'and asteroids...' - WHOOSH

0:11:33 > 0:11:35and meteoroids...

0:11:35 > 0:11:36That's you!

0:11:38 > 0:11:41Well done, ice-skating meteoroids!

0:11:43 > 0:11:44What a busy night sky.

0:11:44 > 0:11:46OWL HOOTS

0:11:46 > 0:11:50It's amazing to think that so many of those faraway stars

0:11:50 > 0:11:55have got planets, comets and asteroids spinning around them!

0:11:56 > 0:12:00All we need to do is look closely for them.

0:12:02 > 0:12:06Let's get cosy underneath the faraway stars

0:12:06 > 0:12:08for a Starlight Story.

0:12:10 > 0:12:14# Starlight scattered through the dark

0:12:17 > 0:12:20# Painting stories for us all

0:12:24 > 0:12:29# Gather underneath the stars

0:12:31 > 0:12:35# And hear their wonders told

0:12:38 > 0:12:41# Looking up into the dark

0:12:41 > 0:12:45# The night is yours and it is mine

0:12:45 > 0:12:49# Looking up into the dark

0:12:49 > 0:12:51# The dark upon us all

0:12:52 > 0:12:55# Upon us all, the stars will shine

0:12:55 > 0:13:02# Upon us all, the stars will shine. #

0:13:02 > 0:13:04Look up there!

0:13:06 > 0:13:10- ALL:- Canis Major - the Big Dog.

0:13:10 > 0:13:14Canis Major, the Big Dog, wished to skate on ice.

0:13:14 > 0:13:17He dreamt of doing fantastic tricks,

0:13:17 > 0:13:20like gliding fast and catching sticks.

0:13:20 > 0:13:23But when the day came to try his skates on,

0:13:23 > 0:13:27before he was ready, the skates - they were gone!

0:13:27 > 0:13:30Over the ice, away the dog flew. His paws got chilly

0:13:30 > 0:13:33and his nose turned blue!

0:13:33 > 0:13:37But then, in slid some penguins in a black and white huddle,

0:13:37 > 0:13:40and swept the dog up in a cosy cuddle.

0:13:40 > 0:13:43They warmed him up as they squeezed him tight.

0:13:43 > 0:13:47His paws thawed out and his nose glowed bright!

0:13:48 > 0:13:52Now, Canis Major is a skating star!

0:13:52 > 0:13:55The crowds come to watch from near and far

0:13:55 > 0:13:58as Canis Major performs his tricks,

0:13:58 > 0:14:01like gliding fast and catching sticks!

0:14:01 > 0:14:05And the Big Dog's rather good on skates...

0:14:05 > 0:14:08thanks to the penguins, his skating mates.

0:14:15 > 0:14:19- Thanks for helping us look at the stars tonight, Maggie.- My pleasure.

0:14:19 > 0:14:23We'll see you tomorrow for some more dustgazing. I mean, stargazing!

0:14:23 > 0:14:25See you tomorrow, bye-bye!

0:14:25 > 0:14:27- ALL:- Bye!
