0:00:06 > 0:00:09so let's all look up at Stargazing Park.

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

0:00:12 > 0:00:16Last night we looked at shooting stars -

0:00:16 > 0:00:19a beautiful sight that's over in a flash.

0:00:19 > 0:00:22A bit like our week here at Stargazing Park.

0:00:22 > 0:00:26But we still have time to explore the night sky tonight.

0:00:26 > 0:00:28Are you ready, stargazers?

0:00:28 > 0:00:30- ALL:- Yes.

0:00:30 > 0:00:32All we need to do is...

0:00:32 > 0:00:34- ALL:- ..look up.

0:00:40 > 0:00:42# When the night falls

0:00:47 > 0:00:51# Turn the lights low, grab a cosy rug

0:00:51 > 0:00:55# Wrap up warm and snug, here we go

0:00:55 > 0:00:58# We're going stargazing

0:00:58 > 0:01:02# Gaze at stars, shining bright

0:01:02 > 0:01:05# We're going stargazing

0:01:05 > 0:01:08# Spot a zooming satellite

0:01:08 > 0:01:11# We're going stargazing

0:01:11 > 0:01:14# Glimpse the moon and the planets above

0:01:14 > 0:01:18# We're going stargazing

0:01:18 > 0:01:21# So just look up

0:01:21 > 0:01:25# Look up, look up. #

0:01:35 > 0:01:39Come and join us underneath the stars.

0:01:39 > 0:01:41- Hi, stargazers.- ALL:- Hi, Maggie.

0:01:43 > 0:01:45What can you see up there?

0:01:47 > 0:01:50It's rainy, we can't see any stars tonight.

0:01:50 > 0:01:53If it wasn't raining, what could you see?

0:01:54 > 0:01:56Stars.

0:01:56 > 0:02:00The Plough, which has seven stars.

0:02:04 > 0:02:09That's true. And there are five stars in Cassiopeia the queen.

0:02:12 > 0:02:16Well done, everyone. You're sounding like expert stargazers.

0:02:16 > 0:02:18Well, it's thanks to you, Maggie.

0:02:18 > 0:02:22Thanks for helping us find out so much about the night sky this week.

0:02:22 > 0:02:24Oh, it's been my pleasure.

0:02:24 > 0:02:28And don't forget, there's so much more to discover.

0:02:28 > 0:02:32Let's keep on gazing at the stars up there,

0:02:32 > 0:02:36they've still got so many wonders to share.

0:02:36 > 0:02:39I wonder who else is looking up tonight.

0:02:48 > 0:02:50It's Robert The Robot.

0:02:50 > 0:02:53# We're going stargazing

0:02:53 > 0:02:56# Da-da-da da-da-da-da Ka-cha!

0:02:56 > 0:02:58# Going stargazing... #

0:02:58 > 0:03:01Oh, hello there, stargazers. It's Robert The Robot here.

0:03:01 > 0:03:04I'm just making sure everything is

0:03:04 > 0:03:07perfectly ready for our stargazing tonight.

0:03:07 > 0:03:09Final checks. Comfy blanket? Check.

0:03:09 > 0:03:11Perfectly plumped cushions? Check.

0:03:11 > 0:03:14- PUFF! - Oh! Oh! Oh, no!

0:03:14 > 0:03:16- STARGAZERS SQUEAL - Oh!

0:03:16 > 0:03:20I can't have space scientist Maggie looking at all of this mess.

0:03:20 > 0:03:22Right, right, I know.

0:03:22 > 0:03:24Come back later to see the amazing space app

0:03:24 > 0:03:26that we made today.

0:03:26 > 0:03:29Maggie's going to love it. Isn't she, everybody?

0:03:29 > 0:03:30- ALL:- Yes!

0:03:30 > 0:03:34I can't wait to see Robert and the stargazers' app.

0:03:34 > 0:03:37Stargazing apps are useful because they help us to understand

0:03:37 > 0:03:39what's happening in the night sky.

0:03:39 > 0:03:42And there really is so much to see up there.

0:03:42 > 0:03:45Can you see any stars right now, stargazers?

0:03:45 > 0:03:47No, they're all hiding.

0:03:47 > 0:03:50The stars are still there, but you can't see them

0:03:50 > 0:03:51because of the rain clouds.

0:03:51 > 0:03:54How many stars are there in space, Maggie?

0:03:54 > 0:03:56That's a really good question, Laura.

0:03:56 > 0:04:00Let's go in the cafe and we'll try and work it out.

0:04:00 > 0:04:03Now, on a really, really, really clear night,

0:04:03 > 0:04:05we can see about 3,000 stars.

0:04:05 > 0:04:08Chris, could you take a teaspoonful of sand

0:04:08 > 0:04:11and sprinkle it onto our night sky?

0:04:11 > 0:04:13OK, here goes.

0:04:15 > 0:04:18What does this look like, stargazers?

0:04:18 > 0:04:20- ALL:- Stars.- Lots of stars.

0:04:20 > 0:04:25Yes, I'm making a picture of the night sky with sand.

0:04:25 > 0:04:28It's full of stars.

0:04:29 > 0:04:33But that's just the start of all the stars in space.

0:04:33 > 0:04:36This is a picture of what we think our galaxy,

0:04:36 > 0:04:38the Milky Way, looks like.

0:04:38 > 0:04:42And can you see, it's got lots and lots of stars?

0:04:42 > 0:04:46So if we were to make a picture, with sand, of the Milky Way,

0:04:46 > 0:04:50how much sand do you think we'd need for all those stars?

0:04:50 > 0:04:54Well, there's quite a lot of sand in that jar, Maggie. Is that enough?

0:04:54 > 0:04:57Not quite, Chris. Have a look at these pictures.

0:04:57 > 0:04:58Bucket.

0:05:01 > 0:05:05- ALL:- Suitcase.- Suitcase, yeah.

0:05:05 > 0:05:08- ALL:- A van.

0:05:08 > 0:05:11- ALL:- Wheelbarrow.- And...

0:05:11 > 0:05:13Dumper truck.

0:05:13 > 0:05:15So which one of these do you think

0:05:15 > 0:05:16has enough sand to draw

0:05:16 > 0:05:20a picture of all the stars in the Milky Way?

0:05:20 > 0:05:22- ALL:- The dumper truck!

0:05:22 > 0:05:26You're right. We actually need a dumper truck piled full of sand.

0:05:26 > 0:05:30- That's a lot of stars. - Around 200 billion of them.

0:05:30 > 0:05:32- ALL:- Wow!

0:05:32 > 0:05:36And it doesn't stop there. Space has got lots and lots

0:05:36 > 0:05:37and lots of galaxies.

0:05:37 > 0:05:40Then there must be billions and billions

0:05:40 > 0:05:42and billions of stars in space.

0:05:42 > 0:05:45So where could we get enough sand to draw

0:05:45 > 0:05:48all the stars in the universe, stargazers?

0:05:48 > 0:05:51- Beach?- Beach?- Desert.- In the desert?

0:05:51 > 0:05:55Even if you used all the sand from all the sandy places on Earth,

0:05:55 > 0:05:58you wouldn't have enough sand to make a picture of them.

0:05:58 > 0:06:00There are just too many stars.

0:06:00 > 0:06:05No wonder there's still so much to discover about the night sky.

0:06:05 > 0:06:10Thankfully, we have apps like Robert The Robot's galaxy gallery app.

0:06:12 > 0:06:15Stargazers, welcome to Jodrell Bank.

0:06:15 > 0:06:18Now, very clever space scientists work here,

0:06:18 > 0:06:23exploring space using this giant telescope.

0:06:23 > 0:06:25They are expert stargazers.

0:06:25 > 0:06:26Now, being a robot,

0:06:26 > 0:06:30I like to think I am a bit of an expert stargazer myself.

0:06:30 > 0:06:35In fact, I have invented my very own galaxy gallery app.

0:06:35 > 0:06:37Prepare to be amazed as it reveals

0:06:37 > 0:06:41beautiful pictures of the wonders of the galaxy.

0:06:41 > 0:06:43BZZZRRR!

0:06:43 > 0:06:45Maybe it's got some dust in it. Hang on.

0:06:45 > 0:06:47BEEP! BEEP!

0:06:47 > 0:06:48- HE LAUGHS - It's fixed.

0:06:48 > 0:06:51- TABLET:- 'Deleting galaxy gallery app.'

0:06:51 > 0:06:52What?

0:06:52 > 0:06:54'Deleting galaxy gallery app.'

0:06:54 > 0:06:57How can you be so calm about this?!

0:06:57 > 0:06:59'Galaxy gallery app deleted.'

0:06:59 > 0:07:01No-o-o-o...

0:07:04 > 0:07:07Oh, dot my diodes.

0:07:07 > 0:07:11All of my beautiful galaxy gallery pictures have disappeared.

0:07:11 > 0:07:14All I managed to do was take a silly selfie.

0:07:14 > 0:07:16STARGAZERS GIGGLE

0:07:16 > 0:07:19Oh, it's a good job I remembered to polish my face today.

0:07:19 > 0:07:23I'm looking very shiny, aren't I, stargazers?

0:07:23 > 0:07:25Shining like the moon.

0:07:25 > 0:07:27Let's upload it to the app.

0:07:27 > 0:07:29Cosmic plan.

0:07:29 > 0:07:33Uploading shiny moon me to the galaxy gallery app.

0:08:11 > 0:08:15'The Plough is just one part of the big constellation Ursa Major,

0:08:15 > 0:08:18'the Great Bear.'

0:08:18 > 0:08:20Wonderful work, stargazers.

0:08:20 > 0:08:24Now let's upload some more pictures to the galaxy gallery. Come on.

0:08:26 > 0:08:28Venus.

0:09:24 > 0:09:26'Billions and billions and billions...'

0:09:26 > 0:09:30Oh, dear, stargazers. It sounds like the app is stuck.

0:09:30 > 0:09:32- HE GASPS - It's breaking again.

0:09:32 > 0:09:33Pani-i-c!

0:09:33 > 0:09:35'Not stuck, Robert,

0:09:35 > 0:09:38'just saying how many stars there are in the universe.

0:09:38 > 0:09:40'There's billions of them.

0:09:40 > 0:09:42'Galaxy gallery completed.'

0:09:42 > 0:09:45BEEP! BEEP!

0:09:45 > 0:09:47Thank you for all your help, stargazers.

0:09:47 > 0:09:52The galaxy gallery app is once again full of beautiful pictures.

0:09:52 > 0:09:55We are definitely expert stargazers.

0:09:55 > 0:09:57- ALL:- Yay!

0:09:57 > 0:09:58Well done, everyone.

0:09:58 > 0:10:02The pictures in your app remind me of the beautiful things we've

0:10:02 > 0:10:04looked at this week.

0:10:04 > 0:10:06Stars...

0:10:06 > 0:10:08planets...

0:10:08 > 0:10:10shooting stars.

0:10:10 > 0:10:15And there's one more exciting thing that we've seen...

0:10:15 > 0:10:20a dot of light moving across the night sky.

0:10:20 > 0:10:23- ALL:- The International Space Station.

0:10:23 > 0:10:26With astronaut Tim Peake onboard.

0:10:30 > 0:10:34Just before Christmas, Tim launched up into space

0:10:34 > 0:10:36with two other astronauts.

0:10:37 > 0:10:40Look at the rocket go!

0:10:45 > 0:10:48After just nine minutes, Tim was in space.

0:10:50 > 0:10:52And six hours later,

0:10:52 > 0:10:57Tim and the other astronauts arrived at the International Space Station.

0:10:57 > 0:11:01Tim spent Christmas on the Space Station and will be there

0:11:01 > 0:11:04until the summer.

0:11:04 > 0:11:10Here's astronaut Tim to say hello to us from space.

0:11:10 > 0:11:12Hello, Chris. Hello, stargazers.

0:11:12 > 0:11:14It's Tim Peake here.

0:11:14 > 0:11:17Welcome onboard the International Space Station.

0:11:17 > 0:11:20Thank you for getting involved in my mission,

0:11:20 > 0:11:24and for wearing your mission patches, just like mine.

0:11:24 > 0:11:26It's fantastic being up here in space.

0:11:26 > 0:11:30I've been very busy getting to work on lots of experiments,

0:11:30 > 0:11:33and helping another astronaut settle in...

0:11:33 > 0:11:36- 'Reporting for duty.' - ..Miss Mouse, yes.

0:11:36 > 0:11:38Miss Mouse did so well on her training,

0:11:38 > 0:11:40she got to come along, too.

0:11:40 > 0:11:45Come on, Miss Mouse. Let's show everybody what we can do in space.

0:11:45 > 0:11:47'Whee!'

0:11:49 > 0:11:52Wow, Tim is at the Space Station,

0:11:52 > 0:11:55and clever Miss Mouse is there, too.

0:11:55 > 0:11:58All week we've been joining in with his mission.

0:11:58 > 0:12:01We've been wearing his mission patches

0:12:01 > 0:12:03while finding out about space.

0:12:03 > 0:12:06And of course, we've been giving him a big thumbs up.

0:12:06 > 0:12:08And you've been joining in, too.

0:12:08 > 0:12:11Thank you for uploading your thumbs-up pictures to

0:12:58 > 0:13:01Thank you so much for getting involved in my mission.

0:13:01 > 0:13:04Thumbs up, stargazers.

0:13:04 > 0:13:06Come on, stargazers,

0:13:06 > 0:13:10let's get cosy for one more story under the stars.

0:13:17 > 0:13:21I wonder whose story they'll tell tonight.

0:13:21 > 0:13:23Look up there...

0:13:25 > 0:13:29Andromeda the princess.

0:13:29 > 0:13:34Andromeda the princess wished to drive a dumper truck.

0:13:34 > 0:13:41A dumper truck so ginormous, for delivering loads so very enormous.

0:13:41 > 0:13:45She drove a load of ice to Saturn, to make its shiny rings.

0:13:45 > 0:13:49And took the giant Jupiter to the space where it now spins.

0:13:49 > 0:13:56Then one day, Andromeda delivered the biggest load by far...

0:13:56 > 0:14:00billions and billions and billions and billions and billions

0:14:00 > 0:14:03and billions of stars.

0:14:03 > 0:14:07The truck, it trundled over a hill and down a bumpy road.

0:14:07 > 0:14:10Bumpity-bump, the dumper truck went

0:14:10 > 0:14:12and out flew the starry load.

0:14:12 > 0:14:15Off the stars twirled...

0:14:15 > 0:14:17they whirled and swirled

0:14:17 > 0:14:20and the princess looked up with glee

0:14:20 > 0:14:23at a galaxy jam-packed full of stars...

0:14:23 > 0:14:26what a wonderful sight to see.

0:14:28 > 0:14:32Thank you so much for showing us around the night sky, Maggie.

0:14:32 > 0:14:36My pleasure. Remember, if you see the International Space Station,

0:14:36 > 0:14:38- give Tim a...- ALL:- ..thumbs up!

0:14:38 > 0:14:41- Bye-bye. ALL:- Bye.
