0:00:00 > 0:00:05See you!
0:00:05 > 0:00:06Morning, guys.
0:00:06 > 0:00:08Martin here with your Monday Newsorund.
0:00:08 > 0:00:08Coming up:
0:00:08 > 0:00:12We all love space, but have you ever wondered how big it is?
0:00:12 > 0:00:18We've been finding out.
0:00:18 > 0:00:26And we meet the 13-year old ice skaing world champion.
0:00:29 > 0:00:31OK, let's start with a quick round-up of some
0:00:31 > 0:00:32of the day's sports stories.
0:00:32 > 0:00:35First, to the Winter Paralympics, and on the ice, Great Britain's
0:00:35 > 0:00:39curling team are leading Sweden in their latest round robin match.
0:00:39 > 0:00:42But it's been bad news for the british para-snowboarding team -
0:00:42 > 0:00:46they have been knocked out in the qulifying round.
0:00:46 > 0:00:49Now, sticking with winter sports, try not to get too dizzy
0:00:49 > 0:00:50when you watch this.
0:00:50 > 0:00:52This is 13-year-old Alexandra Trusova who came first
0:00:52 > 0:00:54in the junior figure skating World Championships.
0:00:54 > 0:00:56She already has loads of world records and is now
0:00:56 > 0:01:04the youngest ever World Champ.
0:01:05 > 0:01:07Scotland have beaten Ireland for the first time
0:01:07 > 0:01:10in Women's Six Nations history.
0:01:10 > 0:01:13Chloe Rollee ran practically the entire length of the pitch
0:01:13 > 0:01:16to score the second of the Scots' two tries, as they won 15-12.
0:01:16 > 0:01:19And starying with Scotland, there was a cracking Old Firm derby
0:01:20 > 0:01:22And staying with Scotland, there was a cracking Old Firm derby
0:01:22 > 0:01:25in the Scottish Premiership - Josh Windass put Rangers ahead
0:01:25 > 0:01:26at Ibrox after just three minutes.
0:01:26 > 0:01:28It was 2-2 at half-time before Celtic snatched victory,
0:01:28 > 0:01:31thanks to Odsonne Edouard.
0:01:31 > 0:01:34Here on Newsround we love hearing about you, so we ve traveled
0:01:34 > 0:01:36all over the country to hear some of your amazing stories.
0:01:36 > 0:01:39This week we re hearing from Kane, who found his forever family
0:01:39 > 0:01:44when he was adopted.
0:01:44 > 0:01:49My birth parents, I mean, they did love me, but they just
0:01:49 > 0:01:51couldn't look after me, so it's really nice to know
0:01:51 > 0:01:59that I now have parents who can look after me.
0:02:01 > 0:02:04Hi, I'm Kane, I'm 15 and I've found my forever family.
0:02:04 > 0:02:06I've always known I've been adopted and I think that's
0:02:06 > 0:02:08really good because, you know, it's not any secret
0:02:08 > 0:02:10that is being kept from me.
0:02:10 > 0:02:12It's good to know what's happened previously, stuff that
0:02:12 > 0:02:13I might not have remembered.
0:02:13 > 0:02:16In primary school when I told my friends, a couple of them had been
0:02:16 > 0:02:18teasing me about not having parents.
0:02:18 > 0:02:22It felt a bit, you know, not very happy because I guess
0:02:22 > 0:02:25I was kind of jealous that other people had their parents who they'd
0:02:25 > 0:02:28lived with all their lives.
0:02:28 > 0:02:31But on the other hand, I was so happy because I did
0:02:31 > 0:02:33have a mum and dad.
0:02:33 > 0:02:36My brother that I have in my forever family was also adopted
0:02:36 > 0:02:39from a different family into the one we both share now.
0:02:39 > 0:02:41I don't think being adopted has changed anything.
0:02:41 > 0:02:47We still have fun and fights.
0:02:47 > 0:02:50What might've happened?
0:02:50 > 0:02:53Um...
0:02:53 > 0:02:55I wouldn't be having the life I have now,
0:02:55 > 0:03:00which is really good.
0:03:00 > 0:03:08It's just kind of shown how important people are in our lives.
0:03:09 > 0:03:11Next, we all know that space is pretty huge,
0:03:11 > 0:03:12but just how big actually is it?
0:03:12 > 0:03:15That's what Oscar at Hutton Rudby Primary School wanted to know.
0:03:15 > 0:03:25Here's space expert Sarah Bosman with the answer.
0:03:35 > 0:03:38Hello, I'm Sarah Bosman and I am an astrophysicist at UCL.
0:03:38 > 0:03:39I study mostly the early universe.
0:03:39 > 0:03:40Space is really enormous.
0:03:40 > 0:03:42It's so big that it's kind of hard to imagine.
0:03:42 > 0:03:50The units we use on Earth, like kilometres or miles,
0:03:50 > 0:03:52don't even make sense to apply to space because you'll
0:03:52 > 0:03:55just get too many zeros if you try to think of it that way.
0:03:55 > 0:03:58So astronomers have to come up with a whole new unit
0:03:58 > 0:04:00to measure distances in space, which is a light year.
0:04:00 > 0:04:03So for instance, a galaxy is 100,000 light years
0:04:03 > 0:04:04from one edge to the other.
0:04:04 > 0:04:07That means if you are travelling at the speed of light,
0:04:07 > 0:04:10which is the fastest you can ever go, it will still take you 100,000
0:04:10 > 0:04:12years from one edge to the other.
0:04:12 > 0:04:15And that's only how big one galaxy is, so if we look outside
0:04:15 > 0:04:18of our galaxy to how many other galaxies there are, we just study
0:04:18 > 0:04:22small patches of the sky and count how many there in each small patch.
0:04:22 > 0:04:26And the amount of galaxies we think are in the universe,
0:04:26 > 0:04:31it's about two trillion galaxies, which is a ridiculous number.
0:04:31 > 0:04:33So if you took all those galaxies and split them
0:04:33 > 0:04:35among everyone on Earth, each person would have about 250
0:04:35 > 0:04:37galaxies all to themselves.
0:04:37 > 0:04:38And that's only the space we know about.
0:04:38 > 0:04:45Beyond that, there could be even more space.
0:04:45 > 0:04:47That's it from me for now.
0:04:47 > 0:04:52I'll be back at about 8.20am.
0:04:52 > 0:05:00Don't forget to head online for the rest of the day's stories.
