0:00:03 > 0:00:04Morning, guys.
0:00:04 > 0:00:06Martin here with your Monday Newsorund.
0:00:06 > 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 > 0:00:13We've been finding out.
0:00:13 > 0:00:21And we meet the 13-year old ice skaing world champion.
0:00:28 > 0:00:31OK, let's start with a quick round-up of some
0:00:31 > 0:00:31of the day's sports stories.
0:00:31 > 0:00:34First, to the Winter Paralympics, and on the ice, Great Britain's
0:00:34 > 0:00:36curling team are leading Sweden in their latest round robin match.
0:00:36 > 0:00:39But it's been bad news for the british para-snowboarding team -
0:00:39 > 0:00:45they have been knocked out in the qualifying round.
0:00:45 > 0:00:47Now, sticking with winter sports, try not to get too dizzy
0:00:47 > 0:00:48when you watch this.
0:00:48 > 0:00:50This is 13-year-old Alexandra Trusova who came first
0:00:50 > 0:00:53in the junior figure skating World Championships.
0:00:53 > 0:00:55She already has loads of world records and is now
0:00:55 > 0:01:03the youngest ever World Champ.
0:01:03 > 0:01:05Scotland have beaten Ireland for the first time
0:01:05 > 0:01:06in Women's Six Nations history.
0:01:06 > 0:01:08Chloe Rollie ran practically the entire length of the pitch
0:01:08 > 0:01:15to score the second of the Scots' two tries, as they won 15-12.
0:01:15 > 0:01:17And staying with Scotland, there was a cracking Old Firm derby
0:01:17 > 0:01:20in the Scottish Premiership - Josh Windass put Rangers ahead
0:01:20 > 0:01:21at Ibrox after just three minutes.
0:01:21 > 0:01:23It was 2-2 at half-time before Celtic snatched victory,
0:01:23 > 0:01:29thanks to Odsonne Edouard.
0:01:29 > 0:01:32Here on Newsround we love hearing about you, so we ve travelled
0:01:32 > 0:01:35all over the country to hear some of your amazing stories.
0:01:35 > 0:01:38This week we re hearing from Kane, who found his forever family
0:01:38 > 0:01:45when he was adopted.
0:01:45 > 0:01:48My birth parents, I mean, they did love me, but they just
0:01:48 > 0:01:50couldn't look after me, so it's really nice to know
0:01:50 > 0:01:55that I now have parents who can look after me.
0:01:55 > 0:01:58Hi, I'm Kane, I'm 15 and I've found my forever family.
0:01:58 > 0:02:00I've always known I've been adopted and I think that's
0:02:00 > 0:02:04really good because, you know, it's not any secret
0:02:04 > 0:02:05that is being kept from me.
0:02:05 > 0:02:08It's good to know what's happened previously, stuff that
0:02:08 > 0:02:10I might not have remembered.
0:02:10 > 0:02:13In primary school when I told my friends, a couple of them had been
0:02:13 > 0:02:15teasing me about not having parents.
0:02:15 > 0:02:19It felt a bit, you know, not very happy because I guess
0:02:19 > 0:02:22I was kind of jealous that other people had their parents who they'd
0:02:22 > 0:02:23lived with all their lives.
0:02:23 > 0:02:29But on the other hand, I was still happy because I did
0:02:29 > 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 > 0:02:40from a different family into the one we both share now.
0:02:40 > 0:02:43I don't think being adopted has changed anything.
0:02:43 > 0:02:48We still have fun and fights.
0:02:48 > 0:02:51What might've happened?
0:02:51 > 0:02:52Um...
0:02:52 > 0:02:55I wouldn't be having the life I have now,
0:02:55 > 0:02:56which is really good.
0:02:56 > 0:03:04It's just kind of shown how important people are in our lives.
0:03:05 > 0:03:07Next, we all know that space is pretty huge,
0:03:07 > 0:03:09but just how big actually is it?
0:03:09 > 0:03:12That's what Oscar at Hutton Rudby Primary School wanted to know.
0:03:12 > 0:03:16Here's space expert Sarah Bosman with the answer.
0:03:16 > 0:03:19Hi, I'm Sarah Bosman and I am an astrophysicist at UCL.
0:03:19 > 0:03:23I study mostly the early universe.
0:03:23 > 0:03:31Space is really enormous.
0:03:33 > 0:03:36Hi, I'm Sarah Bosman and I am an astrophysicist at UCL.
0:03:36 > 0:03:37I study mostly the early universe.
0:03:37 > 0:03:42Space is really enormous.
0:03:42 > 0:03:44It's so big that it's kind of hard to imagine.
0:03:44 > 0:03:47The units we use on Earth, like kilometres or miles,
0:03:47 > 0:03:49don't even make sense to apply to space because you'll
0:03:49 > 0:03:53just get too many zeros if you try to think of it that way.
0:03:53 > 0:03:55So astronomers have to come up with a whole new unit
0:03:55 > 0:03:58to measure distances in space, which is a light year.
0:03:58 > 0:04:00So for instance, a galaxy is 100,000 light years
0:04:00 > 0:04:01from one edge to the other.
0:04:01 > 0:04:04That means if you are travelling at the speed of light,
0:04:04 > 0:04:07which is the fastest you can ever go, it will still take you 100,000
0:04:07 > 0:04:09years from one edge to the other.
0:04:09 > 0:04:12And that's only how big one galaxy is, so if we look outside
0:04:12 > 0:04:15of our galaxy to how many other galaxies there are, we just study
0:04:15 > 0:04:19small patches of the sky and count how many there in each small patch.
0:04:19 > 0:04:21And the amount of galaxies we think are in the universe,
0:04:21 > 0:04:24it's about two trillion galaxies, which is a ridiculous number.
0:04:24 > 0:04:26So if you took all those galaxies and split them
0:04:26 > 0:04:28among everyone on Earth, each person would have about 250
0:04:28 > 0:04:29galaxies all to themselves.
0:04:29 > 0:04:31And that's only the space we know about.
0:04:31 > 0:04:39Beyond that, there could be even more space.
0:04:44 > 0:04:46Finally, robots that think for themselves.
0:04:46 > 0:04:48Sounds futuristic, but they're are already here and scientists
0:04:48 > 0:04:51are using the technology to teach the bots to play football?!
0:04:51 > 0:04:56Watch this.
0:04:56 > 0:04:57Meet the football playing robots.
0:04:57 > 0:05:01They're not being operated by remote control.
0:05:01 > 0:05:03These techie sports stars are making decisions for themselves.
0:05:03 > 0:05:05Scientists at the University of Texas have programmed the robots
0:05:05 > 0:05:08to do use artificial intelligence to have a good old kickabout.
0:05:08 > 0:05:10These guys are in training for a big contest -
0:05:10 > 0:05:16the Robot World Cup.
0:05:16 > 0:05:24Like this one held in Germany two years ago.
0:05:25 > 0:05:27What a save!
0:05:27 > 0:05:29They're able to learn from their mistakes and improve
0:05:29 > 0:05:33their game each time they play.
0:05:33 > 0:05:35Rather than turn taking, everybody's moving at the same time.
0:05:35 > 0:05:38If you take too long to think about what to do when you're
0:05:38 > 0:05:41about to pass the ball the opponents can come and take
0:05:41 > 0:05:42the ball away from you.
0:05:42 > 0:05:46I think these guys have got what it takes to make it to the finals,
0:05:46 > 0:05:48once they learn to stay on the feet, that is.
0:05:48 > 0:05:51That's it from me for now, Ricky is back at 4.20pm.
0:05:51 > 0:05:52Have a great day at school.
0:05:52 > 0:05:55Don't forget to head online for the rest of the day's stories
0:05:55 > 0:05:57and test yourself with our amazing quiz of the week.
0:05:57 > 0:06:02Bye!
