an earth like planet orbiting a distant star we will ask what this discovery by me. i'm sorry kelly welcome to the program china has formally some of the german ambassador to beijing after a meeting between the german foreign minister heikal mosques and the hong kong protest leader joshua walking in berlin earlier this week during his visit wang called on the german government to publicly condemn police violence and abuse of power during the ongoing demonstrations and hong kong now in an unusually direct verbal attack on an important trade partner beijing is warning of negative consequences for relations between china and germany. it was just you were walking search day in berlin he came to the german capital with a message for i'm going to mexico and other world leaders is

a must for to pay attention to hong kong's protests and showed us a part to a hong kong summit isolation safeguard hong kong is not only the responsibility of hong kong people but also the responsibility for world leaders prefer to hong kong to face the next tenement square massacre happened for a decade ago on monday wong met german foreign minister heiko must prompting shop criticism from beijing it summons germany's ambassador accusing but then of interfering in china as a fads. only go. and see what happens you know i'm fortunately have to say we'll have negative consequences on bilateral relations and china will have to react you. know if you look at berlin's home old university just one pack type 3 here to his message was one have to finance and a strong belief in the power of the protest movement in his home city no matter

youngster or elderly all we stand as one with our determination to fight for a better future. joshua won't find many supporters in the german capital. i think he did a good job if you like he then at like a hero is that he just he is fair on this about it that he is up a silicate i. don't know because he's very impressive very brave and he's still very young. i find him particularly admirable because he's risking his life in freedom with his activism activism with the skillz i'm person. i think it's a huge motivation for people who are broadly concours abroad to. so be motivated and follow closely to what is happening in our home city. many here tell us that concerned about joshua wong and what will happen to him when he returns to hong kong but 1st he's heading for the united states where he hopes to gain more

support for hong kong's pro-democracy movement. chief political correspondent melinda crane joins me from berlin melinda what does joshua wang want from the german government at a press conference yesterday he listed 3 things he said 1st of all a public government condemnation of police violence and of views of power in hong kong secondly he said that the german government should stop exporting police equipment to hong kong as long as the police are using violence against the protesters and thirdly he suggested that china and germany should link trade with china to human rights saying that it either should suspend trade talks with china as long as the violence continues or insert human rights clauses into trade agreements so 3 very clear messages there to the german government how is the

german government responding. there's a sympathetic ear here in berlin but there's also a certain degree of caution it's unclear to what extent joshua wang explicitly requested a meeting with chancellor angela merkel but he did not get one at any rate and that meeting that took place with the foreign minister mass was actually on the margins of a private reception by the german tabloid newspaper the bill which is in fact the host for joshua long's this is it here in berlin in other words this is not some kind of official government sponsored visit on the other hand we did hear the chancellor say on her recent visit last week to beijing that germany absolutely sees human rights as indispensable and she reiterated that message yesterday in an official address to parliament saying that germany is conveying that message to

beijing so i think there's a little level of caution but certainly also there is pressure from the opposition for the german government to take an even clearer step and i mean there's also pressure from china as we've come to learn china has called the meeting with the foreign minister disrespectful in fact threatened the fact that there could be some retaliation here linda how seriously should germany take this line from china right now. certainly people in the business community will be taking this very seriously china is germany's most important trading partner the 2 countries did 100000000000 euros worth of trade just in the 1st half of this year and german export companies have seen some significant 5 wall bulls in the market thanks to the fact that thanks to the trade tensions between china and the u.s. which have reverberating effects also for germany so there will be a lot of concern about how do we interpret this message from china on the other

hand one must say would it really be in china's interest to open a new front in its tensions with the world community certainly when the chancellor was in beijing there were a lot of friends of friendly signals from the chinese government saying that they had great ties with germany and that the complementary between the 2 showed that relations didn't have to be tense with the west so i think it's it will remain to be seen the degree to which beijing follows through on these threats chief political correspondent linda crane thank you linda. let's get a quick check of some other stories making news around the world newly released british government documents warn of chaos and public disorder if there is a no deal brags that in a worst case scenario the documents predicts severe disruption to cross town routes which could affect supplies of medicine and some food the government was forced to release the files after

a vote by lawmakers. catalan separatist protests in barcelona turned a wagering the night after a largely peaceful demonstration to celebrate the cattle and national day demonstrators descended on catalonia as parliament in an outpouring of pro separatist sentiment and dissatisfaction with the national government in madrid. the body of zimbabwe's former president robert mugabe is lying in state at his private residence in harare. family said that he will be buried next week in his home village and not at a national monument gobby his remains arrived on wednesday from singapore where he died at the age of 95. the 1st nigerians evacuated from south africa have arrived back in the country hundreds of nigerians signed up for free flights home following a wave of violence against foreigners in south africa but while there is relief at having escaped many say that they are on certain what the future holds for them our

correspondent funny for char was one of the 1st international correspondents to meet the rector news at the airport in lagos and sent us this report slowly and with a long delay and finally arrives the airplane from johannesburg jolly's and some officials are waiting for the passengers to disembark. this is the 1st machine from south africa with nigerian rhetoric the 1st since anti immigrant violence erupted in and around your hand last week now that the nigerians are back what does the future hold for that. warm welcome to begin with but a lot of uncertainty to this woman left south africa after 7 years because of the xenophobic attacks she says she has brought her child with her. so. what's the plan for the future and what are you hoping

to. find a job because i'm a graduate. of. hours earlier and just outside of the airport the usual hustle in lagos nigeria is facing chronic unemployment especially among its youth just like south africa this young man studied to be an accountant but can only survive repairing cars he believes the future is bleak for the returning. i feel sorry for them because. they don't have. a question that a senior assistant of president bihari is eager to answer the government has been criticized for not doing enough for the returning a private chose to volunteer to bring some of them home one of the major problems

with the institution is communication so they're going to have sim cards with time that will last them for 2 months that is not what these people want to hear 189 people arrive on the 1st plane tired exhausted and confused expecting more from the government. to provide some. these school halls like electricity and water on good roads you understand me does what's. thing they. very basic moves to start a business like they had in south africa who are they could make a living but were they no longer food. scientists have made a major discovery in the search for life in outer space as this animation shows it's a massive planet orbiting a star more than 110 light years away and water vapor has been discovered on the planet's atmosphere this suggests that it is the right distance from its star

potentially to have temperatures that are suitable to sustain life researchers hope that newer and more powerful telescopes will be able to unlock more secrets on arcelor system. if you have more on this story i'm joined now by derek williams from our science desk so what exactly were the researchers able to detect here the only way they were able to detect these exoplanets at all as when they pass in front of the star that they that they orbit and as they pass in front of the star that they orbit they make it slightly darker on the side facing the earth and and and some of the light that's that's being emitted by the star passes then through that exoplanets atmosphere if it has one and as it passes through that atmosphere electromagnetic waves a very specific parts of the spectrum can be can kind of be weeded out and that creates of fingerprints these compounds that are in the atmosphere complain contain a fingerprint that were then able to read and were able to read that particular

book in this particular moment we found water in the atmosphere or water vapor so water on a distant planet why is it such a big breakthrough well with with planets we're always looking for what we call the habitable zone the circumstance or habitable zone is also called the goldilocks zone that means it's it's not too hot it's not too cold it's just right the problem is of the planet is too close to its star and it heats up and you get this sort of runaway greenhouse effect or or water can just boil off into space if it's if it's too far away and it's too cold then all of the water leaves the atmosphere and ends up as i use on the surface what you want is something in between so we've discovered this that this water vapor is actually there in the atmosphere that indicates some kind of the a water cycle even something approaching weather and that is a key and fundamental aspect of life as we know it the the presence of water of liquid water could humans live there i mean that's a big question that everybody wants to know right you know if at some date in the distant future we were actually able to get there couldn't sustain our life well

we're entering the realms definitely of science fiction when we talk and that directions assuming that it was some very distant day we were actually able to overcome the tremendous that challenges of interstellar travel this would actually not be one of the planets that we would be interested in going to simply because of the fact that it's 9 times the mass of the earth which means you would be 90. times heavier there than you are here there are also a number of of other questions with these super ers exactly how they're made up of the iraqi quarter they have the sort of really thick layer of gas around them it wouldn't be earth like conditions at all but that said it doesn't make it impossible it might be not conducive to human life but that doesn't make it impossible to imagine other life forms developing there eric williams from our science desk fascinating stuff thank you this is news live from berlin up next turning toxic and documentary film about the merger of the chemicals groups by air and monsanto for the latest news don't forget you can always get it on our website
