Its 9am in singapore and 1am in london and 8pm in the evening in washington, where nasa has announced the discovery of seven planets, all of which have the potential to hold life. The cluster of new worlds orbit a smaller star less than a0 light years away. Now, more research is planned to discover whether conditions on the planets are likely to support living organisms. Our science editor, David Shukman has the details. An artists impression of a startling discovery deep in space, around a faint and distant star, much weaker than our sun, is a collection of planets that are surprisingly similar to earth. In all, seven of these worlds have been spotted, and astronomers think it may change the way we look at the night sky. The discovery gives us a hint that finding a second earth is notjust a matter of if, but when. An array of telescopes kept watch on one point in space and what the scientists were looking for were tiny clues about the light of a particular star becoming dimmer, on a regular basis, as planets orbited in front of it. They cant see these new worlds, but they know theyre there. Well we are extremely excited. This is the biggest amount of planets that weve found in one go that look like the earth in composition, size and mass. All seven are close enough to the star and far enough to the star that they could host liquid water, and thats just incredible. This is the latest revelation in a wave of discoveries over the past 25 years of new worlds that exist in Solar Systems beyond our own. The total of these distant planets now stands at well over 3,000. What makes this discovery so unusual is the sheer number of new worlds spotted in one go, seven in all. And crucially, theyrejust the right temperature for liquid water to exist at the surface. Three of them are in whats called the habitable zone, which raises the tantalising possibility that they could conceivably host life. But we wont be getting there in a hurry, theyre a0 light years away. To reach them, using the rockets we have now, would take Something Like 700,000 years. Theres so much to find out about these worlds, whether the artists impressions are right, whether its possible that the conditions for life do exist, and astronomers say theyll be a huge effort to try to find out. The more we look, the more planets we find and the more earth like planets we find, but this is especially exciting because this, sort of, ultra cool star that weve discovered, theyre quite populous throughout our galaxy, and its the first time weve had planets going around a star like this and weve found seven of them. The best hope lies with huge new telescopes thatll come into service soon, improving the chances of getting a really close look at these alien worlds to see, for example, if they do have oceans and maybe, just maybe, discover if there are some hints about life. David shukman, bbc news. Let us bring you more on our Breaking News that donald trump has lifted federal guidelines that said that transgender students should be allowed to use Public School bathrooms and locker room is matching their chosen gender identity. It reverses a directive issued under president 0bama aimed at enhancing transgender rights. Though surprised here. We heard mutterings as might be the case. Yes, we were expecting it at some point today. And indeed it has come through. The reversal of barack 0bamas ruled that allowed transgender students use whichever toilets or locker room is, as you say, that they associated their gender with. Not necessarily the one melbourne with. The news has come to night that this has been lifted. This was in a letter from the education justice this was in a letter from the educationJustice Department this was in a letter from the education Justice Department to schools over the country, saying that the original guidance was confusing, and had led to some lawsuits, and it had in that it states. But the rules came in in may last year under barack obama. And it was all around really looking at the law that stops Sextus Cremation and the interpretation of that, and whether it extended to gender issues. Sex discrimination. It was never legally binding. But resident barack 0bama did say that there could be federal funds withdrawn from schools is schools did not go along with it. That has all now gone away, which some will be very pleased about. This was very controversial, and some people said that this is the government meddling where it does not need to be and that the advice was confusing. But the American Federation of teachers has come out, earlier on today, when they were mumblings of this earlier today, said this would be a major setback for transgender today, said this would be a major setback for tra nsgender rights. Today, said this would be a major setback for transgender rights. But the letter said very explicitly that anti bullying safeguards will not be affected by the change. Reading the latter, it says, schools must ensure that all students, including lg bt ensure that all students, including lgbt student should be on to learn and thrive in a safe environment. But there is some thought that this ruling today might do the exact opposite. Thank you forjoining us. And the other visa Breaking News is still to do with donald trump this hour. Police in the American State Of North Dakota have begun arresting protesters opposed to an oil pipeline there. Some protestors, as you can see here, set fire to their tents before the operation started. Two Native American tribes have tried to block the project saying it creates a risk of pollution and endangers sites they consider sacred. President 0bama halted construction, and within the last hour President Trump has re authorised it. And again staying with trump, the us Secretary Of StateRex Tillerson has arrived in mexico with the two countries facing their most serious rift for years. Some groups are voicing concerns about mr trumps Deportation Plans and the implications it could have on mexico. The meeting with mexicos Foreign Minister looks like it will be translation i want to make it very clear that the government of mexico and the mexican people do not have to accept provision that one government who unilaterally wants to impose on the other, we will not accept it because theres no reason why we should and because its not been the interest of mexico. Let there be no doubt, mexico and the government of mexico will not hesitate to go to international organisations, starting with the united nations. Very interesting. Thats the view from mexico. The white house Spokesman Sean Spicer took a slightly different view. Have a listen to this. I would argue we have a very healthy and robust relationship with the Mexican Government and mexican officials and i think they would echo that same sentiment, president Enrique Pena Nieto has echoed that as well and i think the relationship with mexico is phenomenal right now, and i think there is an unbelievable and robust dialogue between our two nations. And how about this for some edible political coverage . This is a 3d Printer Being used to create pancakes at a festival in moscow. Customers can bring their own images to have them turned into food and as we have been discussing, top american officials have been arriving in mexico. But there is so much ill will at the moment but it does not look like it is going to be a particularly easy from Central America cross the border into the United States its rodeo season deep in the heart of texas. This is a state with a proud heritage and tough people. Texans will tell you theyre god fearing, cattle rearing street talking folk. Inside this arena its strictly apolitical, but outside they dont mince their words. What do you think of the idea of a wall . Perfect. Whys that . Wall it up we dont need the criminals in here. Wall it up the wall will probably never happen just because of geography. That simple. Theres definitely security measures that will be put in place that will definitely help alleviate some of the illegal immigrants, but i agree with him, we need immigration. Most of the time they need water but you do see some carrying fully automatic weapons and youd better keep on going. And some parts of the frontier are easier to cross than others. Im sitting here on the very edge of the United States, thats mexico just over there, you could be across in a couple of minutes, and apart from the river this wire is the only physical barrier separating these two countries. But ranchers worry about a Barrier Slicing through their fertile fields and one republican congressman said the wall would be the most expensive and least effective way to secure the border. And across that divide every week come thousands of families for whom this is a moment of pure joy. Welcome to america yanelli is three years old. Shes been on the road from honduras for 13 perilous days with her mum and her brother. Like everyone arriving today, the family say violence and poverty forced them to flee. Translation it was hard because when youre an adult, you understand, but babies get scared and they cried. There are parts of the forest where you walk in the dark and when the police came, My Little Girl knew she had to hide and stay quiet. The mass here has a latin american rhythm and the Catholic Church is making the moral case for immigration reform. But this bishop says a secure border with mexico depends on solving problems elsewhere in honduras, guatemala and el salvador. People have a right to live in conditions in their own country where they are safe and secure and can provide for their children. And if they dont have those conditions something seriously wrong. The americas are connected, and sometimes we dont always realise how profoundly. These families have made it and are now applying for asylum, but there may soon be another physical barrier to the fulfilment of the american dream. James cook, bbc news, mcallen in texas. Lets get more now on the investigation into the killing of the half brother of north koreas leader. In the latest development, north korea has blamed malaysia for the death of its citizen last week. Posted on the home page of the north koreas official kcna new Agency Website is this statement the biggest responsibility for his death rests with the government of malaysia as the citizen of the dprk died in its land.

And Security Forces are now guarding the mortuary where mr kims body is being kept after an attempted break in occurred. Earlier i spoke to dr Stephen Norper whos a senior director at the Korea Society and a professor of Political Science at Columbia University in new york. It goes to show that there is a ru ptu re it goes to show that there is a rupture now in malaysia in a north korean relations. Malaysia had been a place in Southeast Asia where north koreans were permitted to travel visa free. I suspect that will change. More concerning is china, as well is aligning with north korea on this issue in that kimjong nam, who north korea on this issue in that kim jong nam, who was assassinated, was under chinese protection. Kim jong nam, who was assassinated, was under chinese protectionlj kim jong nam, who was assassinated, was under chinese protection. I want to ask you specifically about the relations between malaysia and north korea. We know they have been cordial. There is no Visa Requirement for travel between these two countries. So what is this likely to do, what impact will it have on the salacious . Clearly, if there is as hit squad with at least eight people and it looks like a state crafted hit on kim jong nam, it really leads to malaysia and authorities with no alternative but to push hard against the north koreans for such a brazen act on its soil. So there will be a tremendous amount of intrigue about this situation that means those relations will be frayed, at best. Malaysia has recalled its ambassadorfrom pyongyang. Yes, we are seeing this dramatic row unfolded when the two. Had you see at panning out over the next few weeks . Damask; me; 5sz that it, eggs.

However, that said, that the row with china is also accelerating. So china is very disturbed because kim jong nam was under its protection. The north koreans seem to violate that. Seem to. So that in the missal test mean that china has pulled back in terms of that coal exports for the year. Seemed. They had cancelled out for the remainder of the future. That is one step that has been taken in ourtwo that is one step that has been taken in our two diplomatic rows between malaysia and north korea and china and north korea. This is newsday on the bbc.
