0:00:05 > 0:00:08Hi, I'm Ricky, and this is Newsround.
0:00:08 > 0:00:10Stephen Hawking, one of the world's most
0:00:10 > 0:00:14famous scientists, has died.
0:00:14 > 0:00:18A spy mystery involving Russia and the UK.
0:00:18 > 0:00:25And we take a look at the Fantastic Beasts sequel.
0:00:32 > 0:00:34First, one of the world's most famous scientists,
0:00:34 > 0:00:39Professor Stephen Hawking, has died at the age of 76.
0:00:39 > 0:00:43I've been looking back at his incredible life.
0:00:43 > 0:00:45Stephen Hawking was passionate about science and the sky -
0:00:45 > 0:00:48even as a child.
0:00:48 > 0:00:52He went on to become one of the most famous scientists of all time,
0:00:52 > 0:00:56after studying physics at Oxford University.
0:00:56 > 0:01:00When he was 21, he was told he had motor neurone disease.
0:01:00 > 0:01:03It meant he had to use a wheelchair and had to talk
0:01:03 > 0:01:06through a special computer.
0:01:06 > 0:01:10But he lived for 50 years longer than doctors expected and went
0:01:10 > 0:01:14on to develop amazing theories that changed the way the world thinks
0:01:14 > 0:01:19about space, stars and the universe.
0:01:19 > 0:01:26I do not have much positive to say about motor neurone disease, but it
0:01:26 > 0:01:30taught me not to pity myself and to get on with what I can still do.
0:01:30 > 0:01:33I am happier now than before I developed the condition.
0:01:33 > 0:01:36His most famous book, A Brief History of Time, sold more
0:01:36 > 0:01:42than 10 million copies around the world.
0:01:42 > 0:01:48A film was made about his life in 2014, and the actor
0:01:48 > 0:01:52who played him, Eddie Redmayne, won an Oscar for his performance.
0:01:52 > 0:01:54Professor Hawking even appeared in The Simpsons.
0:01:54 > 0:01:57His family say he was a great scientist who was brilliant,
0:01:57 > 0:02:00very funny and inspired people across the world.
0:02:00 > 0:02:06He was 76.
0:02:06 > 0:02:08Russia has failed to explain if they had anything to do
0:02:08 > 0:02:12with the poisoning of a spy in the UK.
0:02:12 > 0:02:16Theresa May had given them a deadline of midnight last night.
0:02:16 > 0:02:18It's not yet known exactly what the UK will do next.
0:02:18 > 0:02:22Ayshah has more on this.
0:02:22 > 0:02:25This is Sergei Skripal.
0:02:25 > 0:02:28He's from Russia and was jailed there more than ten years
0:02:28 > 0:02:31ago for being a spy.
0:02:31 > 0:02:35But he was released and now lives here in the UK, in Salisbury.
0:02:35 > 0:02:39Just over a week ago, he was found on a bench in the city centre,
0:02:39 > 0:02:41along with his 33-year-old daughter Yulia.
0:02:41 > 0:02:47They were both very poorly.
0:02:47 > 0:02:50It's thought they'd been poisoned deliberately.
0:02:50 > 0:02:53It is also thought a police man was affected by the poison
0:02:53 > 0:02:54after going to help find out what happened.
0:02:54 > 0:02:59He's in hospital too.
0:02:59 > 0:03:00Skripal spied on Russia, where he's from, for Great Britain.
0:03:00 > 0:03:03And that's why many people think he has been hurt.
0:03:03 > 0:03:05The British Prime Minister says the poison used
0:03:05 > 0:03:08to attack him was made in Russia.
0:03:08 > 0:03:12The Government has concluded that it is highly likely that Russia
0:03:12 > 0:03:15was responsible for the act against Sergei and Yulia Skripal.
0:03:15 > 0:03:20But a member of the Russian government says that's rubbish.
0:03:20 > 0:03:24Skripal and his daughter had been to a restaurant and a pub that day.
0:03:24 > 0:03:27People who had also been there have been told to wash their clothes
0:03:27 > 0:03:30they were wearing and any items they had with them.
0:03:30 > 0:03:33Health experts say the risk to the public is low, though.
0:03:33 > 0:03:36Emergency services and Army experts are investigating and helping
0:03:36 > 0:03:41to keep people safe.
0:03:41 > 0:03:44Manchester United are out of the Champions League.

0:03:50 > 0:03:54with less than 20 minutes left.
0:03:54 > 0:03:57They went on to score a second soon after.
