0:00:05 > 0:00:06Hi, I'm Hayley.
0:00:06 > 0:00:09On Newsround in the next few minutes...
0:00:09 > 0:00:13You tell us your memories of Professor Stephen Hawking.
0:00:13 > 0:00:21Can you guess what this is on display in Leicester?
0:00:28 > 0:00:30First, one of the world's most famous scientists,
0:00:30 > 0:00:34Professor Stephen Hawking, has died.
0:00:34 > 0:00:38Ricky's been looking back at his incredible life.
0:00:38 > 0:00:40Stephen Hawking was passionate about science and the sky -
0:00:40 > 0:00:43even as a child.
0:00:43 > 0:00:47He went on to become one of the most famous scientists of all time,
0:00:47 > 0:00:51after studying physics at Oxford University.
0:00:51 > 0:00:54When he was 21, he was told he had motor neurone disease.
0:00:54 > 0:00:57It meant he had to use a wheelchair and had to talk
0:00:57 > 0:01:00through a special computer.
0:01:00 > 0:01:03But he lived for 50 years longer than doctors expected and went
0:01:03 > 0:01:07on to develop amazing theories that changed the way the world thinks
0:01:07 > 0:01:13about space, stars and the universe.
0:01:13 > 0:01:16I do not have much positive to say about motor neurone disease, but it
0:01:16 > 0:01:22taught me not to pity myself and to get on with what I still could do.
0:01:22 > 0:01:28I am happier now than before I developed the condition.
0:01:28 > 0:01:31His most famous book, A Brief History of Time, sold more
0:01:31 > 0:01:35than 10 million copies around the world.
0:01:35 > 0:01:38A film was made about his life in 2014, and the actor
0:01:38 > 0:01:43who played him, Eddie Redmayne, won an Oscar for his performance.
0:01:43 > 0:01:48Professor Hawking even appeared in The Simpsons.
0:01:48 > 0:01:51His family say he was a great scientist who was brilliant,
0:01:51 > 0:01:55very funny and inspired people across the world.
0:01:55 > 0:01:59He was 76.
0:01:59 > 0:02:02We've been asking you what you thought about Professor Hawking.
0:02:02 > 0:02:05Let's start with Luke, who uses a voice computer,
0:02:05 > 0:02:09like the famous scientist.
0:02:09 > 0:02:10He was humble and a genius.
0:02:10 > 0:02:11He was inspiring.
0:02:11 > 0:02:14Even though he was in a wheelchair and couldn't communicate
0:02:14 > 0:02:18verbally, he still achieved great things and had a great mind.
0:02:18 > 0:02:21I think meeting Stephen Hawking was a
0:02:21 > 0:02:24completely incredible experience.
0:02:24 > 0:02:27Sitting right next to him, chatting about cosmology
0:02:27 > 0:02:35when I was 13 or 14, was really amazing.
0:02:46 > 0:02:49He was a great and inspiration, especially after being told he
0:02:49 > 0:02:51bitterly lifted 24.
0:02:51 > 0:02:54Now, you'll be used to seeing sights like this in the night sky.
0:02:54 > 0:02:57But what if I told you, you could see the moon close up,
0:02:57 > 0:02:58inside a building in Leicester?!
0:02:58 > 0:02:59Intrigued?
0:02:59 > 0:03:00Confused?
0:03:00 > 0:03:01Me too.
0:03:01 > 0:03:03Luckily Ayshah is here to explain more.
0:03:03 > 0:03:05It's not a sight you see everyday in a cathedral.
0:03:05 > 0:03:08A huge replica of the moon hanging from the ceiling.
0:03:08 > 0:03:10But it's here at Leicester Cathedral this week to mark
0:03:10 > 0:03:12British Science Week.
0:03:12 > 0:03:15These schoolchildren from Leicester have been to check it out.
0:03:15 > 0:03:18We have been looking at the moon, which is incredible.
0:03:18 > 0:03:23It is really nice how...it is just an incredible thing to look at.
0:03:23 > 0:03:26I like looking at the moon because it is really big and it has
0:03:26 > 0:03:30got loads of craters.
0:03:30 > 0:03:33It looks like it would be really hard to climb them all.
0:03:33 > 0:03:35I didn't actually know that there was...
0:03:35 > 0:03:37It is bigger than I expected.
0:03:37 > 0:03:42We have been lying under the moon, trying to find the smallest crater,
0:03:42 > 0:03:45and that is the size of Leicester.
0:03:45 > 0:03:47I find it enjoyable to learn about science.
0:03:47 > 0:03:51The moon was made by an artist in the UK called Luke Jerram.
0:03:51 > 0:03:53It's seven metres wide, and he studied Nasa images
0:03:53 > 0:03:58of the moon's surface in detail to help him make the replica.
0:03:58 > 0:04:02Suzie is a scientist and is running activities for children.
0:04:02 > 0:04:05She wants more people to get into science.
0:04:05 > 0:04:07I am here today because I love space science.
0:04:07 > 0:04:10My advice to anyone out there who is interested in science is to
0:04:10 > 0:04:13study hard at school, but also do lots of other activities in
0:04:13 > 0:04:14your spare time.
0:04:14 > 0:04:15And who knows?
0:04:15 > 0:04:17One of you watching could be the next
0:04:17 > 0:04:23person that goes to the moon or even on to Mars.
0:04:23 > 0:04:26The moon is in Leicester until the end of the week, before it
0:04:26 > 0:04:29continues on its world tour.
0:04:29 > 0:04:35Its next stop, the Commonwealth Games in Australia!
0:04:35 > 0:04:37If you fancy heading to Newsround online,
0:04:37 > 0:04:40there's loads of stuff there for you.
0:04:40 > 0:04:42Why not test yourself with our Quiz of the Week?
