0:00:04 > 0:00:06Good morning, I'm Jenny, live with all the big stories
0:00:06 > 0:00:09from around the world this Wednesday.
0:00:09 > 0:00:10Coming up!
0:00:10 > 0:00:14British astronaut Tim Peake shows off some experiments in space.
0:00:14 > 0:00:19Caught on camera - the Australian volcano erupting.
0:00:28 > 0:00:29First, children across Britain linked up with Tim Peake
0:00:31 > 0:00:34on the International Space Station yesterday for a big question
0:00:34 > 0:00:35and answer session.
0:00:35 > 0:00:38The British astronaut has been up there for six weeks,
0:00:38 > 0:00:41but took time out to speak to children and share
0:00:41 > 0:00:42some experiments.
0:00:42 > 0:00:44Leah was there.
0:00:44 > 0:00:50300 children from across the UK here to put their questions to Major
0:00:50 > 0:00:51Tim Peake.
0:00:51 > 0:00:56But not only that, around 300,000 children are also logged on right
0:00:56 > 0:01:02now, all ready to watch that moment live, too.
0:01:02 > 0:01:04Hello to the World Museum in Liverpool.
0:01:04 > 0:01:06I hear you loud and clear, and welcome on board
0:01:06 > 0:01:08the International Space Station to you and to everybody
0:01:08 > 0:01:10who is following the cosmic classroom on the internet.
0:01:10 > 0:01:13Good afternoon.
0:01:13 > 0:01:16What is your favourite button on the ISS, and what does it do?
0:01:16 > 0:01:21This button, on this panel here, actually opens up the door
0:01:21 > 0:01:23to outer space.
0:01:23 > 0:01:26Is there a possibility of a meteor or space junk hitting the ISS?
0:01:26 > 0:01:32Actually, we do get hit by small particles everyday,
0:01:32 > 0:01:36and if ever we are in any danger, then the ISS will simply move us out
0:01:36 > 0:01:39of the way, and we will shift orbits to get out of the way
0:01:39 > 0:01:40of any space debris.
0:01:40 > 0:01:42But it is a great question.
0:01:42 > 0:01:45I was really excited, waiting to be able to go up
0:01:45 > 0:01:49and see him answer live.
0:01:49 > 0:01:52What is your favourite science experiment on the International
0:01:52 > 0:01:54Space Station?
0:01:54 > 0:01:58I do like the vegetables and flowers we are growing in space,
0:01:58 > 0:02:01I think that is really interesting that we can start
0:02:01 > 0:02:02to grow our own food.
0:02:02 > 0:02:09It felt amazing because not a lot of people can just do that.
0:02:09 > 0:02:10And it is amazing how you've actually just spoken
0:02:10 > 0:02:13to an astronaut.
0:02:13 > 0:02:15Tim is expected back in June, but for now he'll continue
0:02:15 > 0:02:21to inspire as many children as he can back down on planet Earth.
0:02:23 > 0:02:25And head to our website for lots more on Tim Peake's
0:02:25 > 0:02:28mission in space.
0:02:28 > 0:02:31Doctors around the world are looking for ways to help thousands of people
0:02:31 > 0:02:34in South and Central America, and the Caribbean, that have been
0:02:34 > 0:02:37affected by a disease called Zika.
0:02:37 > 0:02:40Martin has been looking into what it is and
0:02:40 > 0:02:42how to fight it.
0:02:42 > 0:02:45Zika is a disease carried by mosquitoes.
0:02:45 > 0:02:47When a mosquito bites people, it spreads the disease
0:02:47 > 0:02:49from person to person.
0:02:49 > 0:02:52The types of mosquitoes that carry the disease live in tropical
0:02:52 > 0:02:56countries, so it is not likely to affect the UK.
0:02:56 > 0:02:59When people do catch the virus, usually it is very mild,
0:02:59 > 0:03:03so mild they don't even know they were infected afterward.
0:03:03 > 0:03:05They feel a bit unwell, like they've got
0:03:05 > 0:03:06a cold.
0:03:06 > 0:03:09But it's more serious if a woman is having a baby.
0:03:09 > 0:03:11Scientists say they think it may affect how a baby grows
0:03:11 > 0:03:12before it's born.
0:03:12 > 0:03:15Doctors around the world are now coming up
0:03:15 > 0:03:18with ways to try to deal with Zika.
0:03:18 > 0:03:20While scientists are making new medicines
0:03:20 > 0:03:24and vaccines to stop Zika virus, everyone is going to be working
0:03:24 > 0:03:26to make sure people don't get bit by mosquitoes.
0:03:26 > 0:03:29They're going to try and get rid of the mosquitoes,
0:03:29 > 0:03:33and that will actually stop a lot of different diseases.
0:03:33 > 0:03:36There has a been a big volcanic eruption on a remote island
0:03:36 > 0:03:39in Australian territory outside the Antarctic circle.
0:03:39 > 0:03:42It was filmed by excited scientists carrying out research
0:03:42 > 0:03:47on Heard Island, that's over 4,000km south-west of Perth.
0:03:47 > 0:03:50Let's look at some sport now.
0:03:50 > 0:03:52Leicester City have beaten Liverpool with two more goals
0:03:52 > 0:03:54from Jamie Vardy.
0:03:54 > 0:03:56They are three points clear at the top of the Premiership,
0:03:56 > 0:03:59with 14 games to go.
0:03:59 > 0:04:01Manchester City are putting on the pressure though,
0:04:01 > 0:04:05with Sergio Aguero scoring the only goal away to Sunderland.
0:04:05 > 0:04:08City's goalkeeper, Joe Hart, says the team are determined to take
0:04:08 > 0:04:13home a trophy for Manuel Pellegrini, who leaves at the end of the season.
0:04:15 > 0:04:1716-year-old Katie Swan, from Bristol, is set to become
0:04:17 > 0:04:19Great Britain's youngest tennis Fed Cup player,
0:04:19 > 0:04:22after she was selected by team captain Judy Murray.
0:04:22 > 0:04:26Australian Open semi-finalist Johanna Konta had to pull out
0:04:26 > 0:04:29because of illness.
0:04:31 > 0:04:34And check out these gigantic cartoon characters that have popped up
0:04:34 > 0:04:37at the Yorkshire Sculpture Park near Wakefield .
0:04:37 > 0:04:39They'll be on display for four months.
0:04:39 > 0:04:42They're part of the first solo exhibition in the UK by the US
0:04:42 > 0:04:49artist Brian Donnelly, who's also known by the name Kaws.
0:04:49 > 0:04:51That's all just now, but Newsround is back right
0:04:51 > 0:04:55here at 8.15.
