a supported or not. nasa has spent a lot of money researching space from the ground since the space shuttle was grounded and they have invested lots of money and this is with the sole aim of trying to find life on other planets. we were hoping to bring you a clip of that press conference and we are trying to find it for you. it would be nice to see it for you. it would be nice to see it and see what they had to say. after spending all that money and time, discovering the stars. it is certainly exciting a lot of astronomers at the moment who say this really does confirm whether life can be found on another planet. it is all down to that surface water. i think we can bring you that clip now. don't you just love live television? it is great, isn't it?|j am excited to announce that the nasa tea m am excited to announce that the nasa team have used our space telescope to determine there are seven is

sized planets orbiting the nearby trappist star about a0 light—years away. what's more, as you can say in this illustration, three of these planets, marked in green, are in the habitable area where liquid water can cool on the surface. with the right atmosphere conditions, there could be water on any of these planets. for the first time, we found as many terrestrial planets around a single star and that is the first time we have been able to measure in addition to both the masses and radii of these habitable, is sized planets. these planets are among the best of all the planets we note follow—up, to see for example even telescope we launched last year, the atmosphere and also signatures if there are any. this discovery gives us a hint that finding a second earth is notjust a

matter of if, but when. scientists believe that around every star, they could be one planet, take three, ta ke could be one planet, take three, take five, take seven and you can just imagine how many worlds are out there that have a shot to become a habitable habitable atmosphere and we could explore. what we really have in the story is a major step forward towards answering one of these very questions at the heart of so these very questions at the heart of so many of our philosophers, what we're thinking about when we are by ourselves. that is basically, are we alone out there? we are making a step forward, a leap forward in fact towards answering that question and i'm really excited. it was worth waiting for! for the first time in its 188—year history, london's metropolitan police force will be run by a woman. cressida dick has been described as an exceptional leader with a clear vision for the future. but her appointment hasn't been without criticism.

she was the commander of the operation that led to the fatal shooting ofjean charles de menezes in 2005. she returns to the met with over 30 years of service under her belt. but what are the main challenges she'll face? nick beake has this report. outside the metropolitan police's new headquarters, their commissioner. the first woman to lead the met. it is beyond my wildest dreams, an extraordinary privilege. i'm very humbled. i adore london. i think it's the world's greatest global city. and i love policing and i love the met. but the appointment is controversial. cressida dick was in charge of the operation 12 years ago in which an innocent man was shot dead at stockwell underground station. brazilian electricianjean charles

de menezes was mistaken for a suicide bomber in a fortnight after the 7/7 attacks. ajury laterfound she bore no personal responsibility. i'm completely confident and delighted that we have a candidate who is going to take this on, who is going to be excellent in the role. she has shown the right leadership potential, she has the right experience. cressida dick takes the top job at a time when crime is on the rise. and money is tight. so what do londoners want the police to prioritise? all cyber crime including online fraud and online bullying, trolling, all these things. for me there is a lack of investment in local policing. we recently lost our local police station, it has been sold and turned into flats. the rise in race hate crime and that kind of thing, i would like that to be addressed because we are a multicultural city. and we need to embrace that. my son at the age of 17, his life was suddenly taken away...

in north london today a mother tells schoolchildren about her unbearable loss. yvonne lawson's son godwin was stabbed to death in 2010. she has campaigned tirelessly to reduce knife crime, but it is now on the rise. i would like the commissioner to ensure that police officers work very closely with their local communities to ensure that they build trust. i would also like the police officers to find out the reasons why young people are carrying knives in the first place. but less money could mean a drop in the number of police officers. the rank and file worry it could fall to below 30,000. i cannot see how we can protect the streets in the same way that we do now with 2,500, 3,000 less cops. that is a huge number and that will have a massive effect on all the departments within the metropolitan area. another concern is how to stop young londoners being radicalised.

here in southall, football is used as a way of fighting extremism. i think it is incredibly important that we have the commissioner that has compassion and has that approach where you could speak to the use where you could speak to the youth of london or of this country and embrace them. so many challenges, rising crime and less money. the new boss may soon discover it is tough at the top. well, leroy logan, former superintendent at the metropolitan police joins me now. we were watching the report and you said you knew sadiq khan was going to make this choice? i must admit, i think he was quite clear when sadiq khan took over, he didn't extend the commission's contract more than a year so i think the writing was on

the wall that he wanted a new lead in the police. you cannot get anyone different from cressida dick. i worked with her when she was a commander on the race and violent crime task force so she knows the value of working with communities andi value of working with communities and i dare say i will get a chance to work with her because i'm doing some work on a london advisory board to an all—party parliamentary group on youth violence and that commission work is ongoing. i would like to think net police is a key element of that. —— the met police. i know from working with colleagues in bbc london that knife crime and racism are still problems. trust continues to be a problem. between communities and the police. she has got a lot of work to do. she also has her own trusts or lack of it to

do with as well because ofjean charles de menezes. there is no doubt about her efficiency and effectiveness but it is the spectre of stock stockwell and she will have to work with that. she is a not... i think she understands that you cannot arrest your way out of problems, you have to work the grassroots organisation. it has to be in grassroots organisation. it has to beina grassroots organisation. it has to be in a way that people buy into making safer and stronger communities and i would like to think that we get an extra 8 million eyes and ears on london and of course, nationally, to work with her in the police service as we know it. it is the envy of the world and hopefully, that look and feel will be maintained and i would like to

think she would not go down the road of miniaturisation with taser is because that changes the whole look and feel of policing and we have to make sure we don't have any barriers, we have two build trust and confidence and hopefully we will see her being a lot more effective. you quite rightly said nationalise as well because it is notjust about london. what the met police daz has huge national interest, especially when it comes to terrorism and there will be pressure on her to deal with that when we look at what happened in paris. also at a time when she is facing cutbacks and cost saving as well. it is almost a perfect storm. i think she knows she is up for this, she is the sort of person... i remember being on a home affairs select committee with her, around knife crime, a disproportionality in the justice system, especially for young people. she was willing to make it clear the police had a long way to go but going in the right direction and we need to work with

communities. also, her role as the assista nt communities. also, her role as the assistant commissioner. list operations, that was her last role in the met. i know you work closely with communities, do you think the police becoming an part of communities and gaining that trust actually helps combat terrorism? absolutely. when the met police was invented, they said, the police is the public and the public is the police. i am working with the youth violence commission. the goal away from that, especially in this day and age when they want more for less, you have to work smart and not just harder. you cannot arrest your weight out of problems. she is picking up a lot of pieces. the met had its successes but it has had its

controversies. 0peration yew tree is one of those and it certainly had its successes but also its embarrassments. a lot of people named and shamed and it was accused of being a witch hunt. yes, and i think it is because it is not as intelligence led as it should be. does she know that? of course she does. so we will see a change in our operations are conducted?” does. so we will see a change in our operations are conducted? i think she will learn from her experiences to ensure that she gets... she has a good management board. 0ne to ensure that she gets... she has a good management board. one thing serb burn at has brought in to steady the ship and think she will speedin steady the ship and think she will speed in the ship. how big chains do think we will see? -- how big a change do you think we will see?|j

think it will be more sophisticated and smarter, really utilising all the assets in a more effective way. i would like to think that as the first woman in that role, she will really show the effectiveness of that definitive policing, celebrating diversity, working with communities and grassroots organisations and holding the borough commanders to account. now they are clustering borough ‘s, flattening the organisation, she will be changed manager and hopefully she will be a change agent for the better, not only for london but for the country. you are clearly afan and but for the country. you are clearly a fan and very optimistic but it must oppress people like yourself when you still have to deal with racism in the force and issues within communities as well. and other issues of trust and policing? absolutely. i gave evidence at the

steven lawrence enquiring and said the police service was introducing racism and jack straw really took the recommendations and cressida dick was involved in the roll—out of that. she would learn from that and she would recognise from her own experience as a woman in the organisation that sometimes it is one step forward, two steps back. she will show effectiveness and efficiency, especially working with communities. the latest headlines coming up shortly but first, here is the weather with tomasz schafernaker. some very windy weather on the way in the next 2a hours as storm doris approaches. the worst will probably hit us during the course of tomorrow morning. this is where this is bbc news. the headlines at 8pm...
