:02:32. > :02:36.started, it was 60 hectares. Now today we are sitting at 106 to 1000
:02:37. > :02:40.hectares. That is about the size of London. So we have had some extreme
:02:41. > :02:46.fire behaviour that cause this to happen. We had light precipitation
:02:47. > :02:50.of the winter which led to an early spring, the fields are dry. We have
:02:51. > :02:54.had one temperatures and strong winds for about a week which has

:04:18. > :04:18.Brazilian President Dilma Rousseff It's after the acting speaker
:04:19. > :04:22.of the country's lower house annulled a vote that
:04:23. > :04:24.happened in April. The Senate was due to have its say
:04:25. > :04:27.on the matter on Wednesday. Let's get more on what this
:04:28. > :04:37.all means with the BBC's First, what change led to this?
:04:38. > :04:40.Well, as you have said, everyone in Brazil including the president
:04:41. > :04:44.herself was expecting that she would be suspended from office later this
:04:45. > :04:51.week after the vote in the country's Senate to begin a full impeachment
:04:52. > :04:54.trial against her. "Morning, Another character in this contest, they
:04:55. > :04:56.enter president or chair of the raw house of Congress has thrown
:04:57. > :05:01.everything up in the area by declaring that the vote which took
:05:02. > :05:04.place three weeks ago and the lowest house of Congress should be
:05:05. > :05:07.annulled. He did a variety of reasons saying that the president
:05:08. > :05:10.had not been given a full right of defence and that members of Congress
:05:11. > :05:15.in what was an acrimonious debate athletics be no one what their
:05:16. > :05:19.voting intentions would be before they actually voted and somehow that
:05:20. > :05:23.has been deemed to be present -- prejudicial. It has thrown things up
:05:24. > :05:28.into the air because the Senate has said that it will not accept this
:05:29. > :05:33.ruling. And that it will carry on regardless. What it does do in this
:05:34. > :05:36.very important political and economic climate in Brazil, it needs
:05:37. > :05:41.a laughing stock of the whole process. It throws into doubt what
:05:42. > :05:45.will happen next. And will not the president have to resign later this
:05:46. > :05:49.week? It is almost a farcical situation and the Supreme Court will
:05:50. > :05:51.probably now have to get involved at some stage to determine what happens
:05:52. > :05:55.next. Just reminds us the meaning of
:05:56. > :06:01.impeachment. And what Dilma Rousseff was accused of?
:06:02. > :06:05.It is a good question because the impeachment, the suspension from
:06:06. > :06:08.office or the potential suspension from office of Dilma Rousseff, it
:06:09. > :06:12.relates to some very small charges that she somehow manipulated
:06:13. > :06:16.government accounts to hide the size of the budget deficit. I sat down
:06:17. > :06:20.with Dilma Rousseff for an interview last week and she told me that she
:06:21. > :06:24.declared her innocence and rejected all of the charges against her. Her
:06:25. > :06:27.view is that this impeachment process has more to do with our
:06:28. > :06:32.enemies in Congress trying to get rid of her. There is absolutely no
:06:33. > :06:38.doubt that Dilma Rousseff is deeply unpopular in Brazil. The country's
:06:39. > :06:43.economy is in recession, 10% inflation increasing, unemployment
:06:44. > :06:45.increasing, there is a very big corruption scandal affecting all big
:06:46. > :06:49.local parties and some of Brazil's because businesses. So this is a
:06:50. > :06:55.country in crisis. Dilma Rousseff is no doubt responsible for a lot of
:06:56. > :06:58.that but whether or not she should be impeached because of that is a
:06:59. > :07:01.matter of opinion. But there is no doubt whatsoever that the longer
:07:02. > :07:04.this crisis continues, the longer the impeachment crisis is a
:07:05. > :07:09.drawn-out, the more that result feels in limbo, incomplete
:07:10. > :07:12.suspension, and that is doing Brazil and its economy, in particular, no
:07:13. > :07:19.good at all. Wyre Davies, thank you very much.

:11:47. > :11:57.Why resign now? Well, the centrist party in Austria,
:11:58. > :12:01.the social Democrats that Chancellor Werner Faymann belongs to and his
:12:02. > :12:06.coalition partner the Conservatives, they have been losing ground to the
:12:07. > :12:10.far right for a long time. Both parties were trounced in the
:12:11. > :12:14.presidential election, the first round in April, and ever since then,
:12:15. > :12:17.the Social Democrats have been really split. There has been
:12:18. > :12:22.soul-searching about how they can stop the rise of the far right. And
:12:23. > :12:28.Chancellor Werner Faymann has paid the price of that but any party.
:12:29. > :12:33.There are those in the party who want a move closer to far right,
:12:34. > :12:37.they want to lift the ban on forming a coalition with them. Others have
:12:38. > :12:41.said that the Social Democrats have gone way too far to the right, they
:12:42. > :12:45.have been taking too tough a line on migrants and that they ought to
:12:46. > :12:49.combat to a more middle position. Chancellor Werner Faymann today said
:12:50. > :12:57.that he did not have the support of his party, so he was stepping down.
:12:58. > :12:59.He changed his stance on the migrant crisis to a harder one but to no
:13:00. > :13:05.avail. Indeed, last summer, when migrants
:13:06. > :13:10.first started coming across the border from Hungary, he welcomed
:13:11. > :13:13.them with open arms, telling them that Austria would take them home.
:13:14. > :13:19.And in fact, watched as they can in 19,000 asylum seekers in the last
:13:20. > :13:23.few months. But then, the far-right started profiting from this, the
:13:24. > :13:32.government took a much harsher line, they brought in a very tough law on
:13:33. > :13:37.asylum, and at the moment it seems it was getting too, located in the
:13:38. > :13:41.party and Chancellor Werner Faymann is very, very split, and they are
:13:42. > :13:47.now looking for a new leader. Bethany Bell, briefly if you will,
:13:48. > :13:50.what do they expect to happen next? The Social Democrats must now decide
:13:51. > :13:53.who will take over from Chancellor Werner Faymann as party leader, then
:13:54. > :14:00.they will have to speak to their coalition partners to see if they
:14:01. > :14:04.will accept him as Chancellor. Then they both will have to decide
:14:05. > :14:08.whether they will call new elections or not, that would be a risky move
:14:09. > :14:13.for both of them, because at the moment the far right Freedom party
:14:14. > :14:16.is topping the polls. And then they will wait to see what happens in the
:14:17. > :14:20.second round of the presidential election later this month.

:20:39. > :20:40.of the little planet that is closest to the Sun.
:20:41. > :20:44.The Royal Astronomical Society laid on a variety of
:20:45. > :20:49.All you can see is a small black dot, but the sight of this distant
:20:50. > :20:53.Despite being a tiny dot, it has an incredible beauty of its own.
:20:54. > :20:58.The last time I saw this was back in 2003, so I'm just as excited
:20:59. > :21:01.Most people here will never have seen anything like this.
:21:02. > :21:03.The overwhelming majority of the world's population probably
:21:04. > :21:09.Those things together make it something to celebrate.
:21:10. > :21:11.A lot about Mercury is still a mystery.
:21:12. > :21:15.In this image from a Nasa spacecraft, the colours represent
:21:16. > :21:17.the highs and lows of a landscape battered by meteorites
:21:18. > :21:22.It's a planet that has long been fascinating.
:21:23. > :21:25.A couple of hundred years ago, astronomers studied planets
:21:26. > :21:28.like Mercury to measure their distance from Earth,
:21:29. > :21:31.and so try to calculate the size of the Solar System.
:21:32. > :21:36.Today is just about a very exciting sight.
:21:37. > :21:39.So, from a distance of 48 million miles, we have been able to watch
:21:40. > :21:44.this strange world racing past the turbulent surface of the Sun.
:21:45. > :21:46.A journey of seven hours is now almost over.
:21:47. > :22:06.With me to talk more about this is Doctor Marek Kukula,
:22:07. > :22:10.Public Astronmer at London's Royal Observatory in Greenwich.
:22:11. > :22:18.There are 20 minutes left of clear skies a few want to view it. With
:22:19. > :22:20.the right equipment we can see the planet Mercury moving.
:22:21. > :22:25.That is what we are looking at now. This is a very clear view. In one
:22:26. > :22:29.second B will see the planet Mercury going across. Just this tiny dot
:22:30. > :22:33.that you can make it out on your screens. This is an amazingly fast
:22:34. > :22:37.transit, even though it might look so do others.
:22:38. > :22:40.Absolutely, it is an object the size of Africa and you are watching it
:22:41. > :22:44.moving at 50 kilometres per second as it moves in orbit around the sun.
:22:45. > :22:46.It really is a chance to see the mechanics of the solar system in
:22:47. > :22:49.action. It is to do with the alignment of
:22:50. > :22:53.the planets around the sun. This only comes around a few times each
:22:54. > :22:56.century. That is correct, the orbits of the
:22:57. > :22:59.planets are not perfectly circular or perfectly aligned with each
:23:00. > :23:03.other, so there are only seven points would you can actually see
:23:04. > :23:11.the sun, Mercury and the Earth precisely lined up like this. It
:23:12. > :23:13.does not happen every day or even every year.
:23:14. > :23:14.What can you learn from seeing something like this happen?
:23:15. > :23:19.Historically, transits like this have been hugely important. In the
:23:20. > :23:21.17th, 18th and 19th century, it helped astronomers to work out how
:23:22. > :23:27.big the source of the Moors, giving us an idea of how teeny beware. Now
:23:28. > :23:34.the use transits to work out how many stars they have around us.
:23:35. > :23:37.There has been a fuse amount of enthusiasm about this, people have
:23:38. > :23:40.been looking at this and all sorts of ways.
:23:41. > :23:43.Absolutely. There have been organised events, not just around
:23:44. > :23:48.the UK but across the world. A huge chunk of the surface of the Earth
:23:49. > :23:51.has been able to see this transit. This is the Tadic from the USA, it
:23:52. > :23:56.is stunning. The European Space Agency... You can
:23:57. > :24:03.still see the live streaming from the space craft which is above the
:24:04. > :24:05.clouds. Amazing views. Something that famous astronomers from the
:24:06. > :24:10.17th century would have given the right and four.
:24:11. > :24:17.We do not hear an awful lot about Mercury, we hear about Mars, Mercury
:24:18. > :24:21.has some mystery and is enigmatic. Yes, it is harder to get to because
:24:22. > :24:25.it is closer to the sun, it has been neglected. That is changing, and the
:24:26. > :24:28.next few years we will see more missions going to look at that. It
:24:29. > :24:33.could have helped in the formation of the Earth is, so we could learn
:24:34. > :24:37.more about ourselves looking at Mercury.
:24:38. > :24:41.We know on one side it is extremely hot, the side-effects from the sun,
:24:42. > :24:44.it is extreme hot. The side facing away from the sun is one of the
:24:45. > :24:49.callers quizzes and solar system. There is now are there to carry the
:24:50. > :24:54.heat of the sun, so if you can not see the sun, it is extremely cold.
:24:55. > :25:01.It has a large iron core? That is right, just the Earth has one, Negri
:25:02. > :25:03.has a iron court. How it came to others enormous squad, it is a huge
:25:04. > :25:10.mystery. In terms of interest, are you saying
:25:11. > :25:14.each time there is an event like this with social media, it is
:25:15. > :25:16.getting even more fascination spread further across the globe, there is
:25:17. > :25:19.real excitement about events like this?
:25:20. > :25:25.People have always been interested about astronomy, 250 years of
:25:26. > :25:30.evidence proves that. But with the Internet, great magazines and TV,
:25:31. > :25:33.you get a chance to experience it in full colour for yourself. I think
:25:34. > :25:37.that people will get fed up of space and then something like this happens
:25:38. > :25:40.and Greenwich has been inundated with people dying to see things
:25:41. > :25:43.through their telescopes. Another chance to see one in two
:25:44. > :25:47.years' time? Three years' time. If you missed the
:25:48. > :25:50.today, you will have an opportunity any few years.
:25:51. > :25:52.Thank you very much for coming in and speaking to us about that.
:25:53. > :25:55.You can get in touch with me and some of
:25:56. > :25:56.the team via Twitter - I'm @KarinBBC.
:25:57. > :26:06.But for now, from me and the rest of the team, goodbye.
