On the way - how prepared are we for the next solar superstorm? And | :00:12. | :00:18. | |
out with the nowt - the school which has banned slang words. | :00:18. | :00:27. | |
nowt., It's nothing. All this to come, but first they | :00:27. | :00:34. | |
happen every 100-200 years, massive radiation blasts from the sun, | :00:34. | :00:38. | |
which could cause electricity blackouts and even disrupt aircraft. | :00:39. | :00:43. | |
They are called solar superstorms. The UK should be able to cope when | :00:43. | :00:50. | |
the next one hits. Nel's been looking into this. The sun is an | :00:50. | :00:55. | |
explosive place. It often throws out blasts of energy and particles. | :00:55. | :01:00. | |
Every few hundred years though, the energy from a massive explosion | :01:00. | :01:03. | |
hits Earth. After travelling through space at one million miles | :01:03. | :01:09. | |
an hour. This is known as a solar superstorm. Scientists say the | :01:09. | :01:15. | |
Earth will be hit by one at some point. The magnetic fields are | :01:15. | :01:19. | |
incredibly strong. Basically, the magnetic field gets stressed and | :01:19. | :01:23. | |
then breaks and explodes. That gives a big burst of energy. You | :01:23. | :01:28. | |
can think of the magnetic field as like a rubber band. If I stretch | :01:28. | :01:32. | |
this rubber band and I have my cloud of charged particles ready, | :01:32. | :01:38. | |
if I then let go - the cloud of charged particleed fly off into | :01:38. | :01:44. | |
space. The last time a super solar storm hit Earth was 1859. All over | :01:44. | :01:50. | |
the planet people reported seeing colourful shows in the night skies. | :01:50. | :01:55. | |
Birds began to sing thinking dawn had arrived. How prepared are we | :01:55. | :02:00. | |
this time around? According to the findings of an expert panel the UK | :02:00. | :02:04. | |
would cope well. The huge bursts of radiation could cause some problems | :02:04. | :02:08. | |
- power cuts, for example, planes would be grounded and GPS | :02:08. | :02:14. | |
satellites that help us found our way around will stop working. It | :02:14. | :02:18. | |
has been compared to what happened when the volcano erupted in Iceland | :02:18. | :02:23. | |
three years ago, creating a huge ash cloud. That stopped thousands | :02:23. | :02:30. | |
of plane journeys and lasted a few weeks. Super solar storms only | :02:30. | :02:34. | |
happen every couple of hundred years. When one hits we could be | :02:34. | :02:40. | |
treated to some spectacular scenes in the night sky. Head over to the | :02:40. | :02:44. | |
Newsround website to check out Joe's guide to the sun. Next, | :02:44. | :02:49. | |
there's another warning today about the threat to elephants in Africa | :02:49. | :02:54. | |
from poaching. Conversationists say the problems in ga bon is out of | :02:54. | :02:59. | |
control. They say more than 11,000 elephants have been killed since | :02:59. | :03:04. | |
2004. The demand for ivory in parts of Asia for things like jewellery, | :03:04. | :03:08. | |
cuff links and medicines is behind the trade. It is hoped a big | :03:08. | :03:12. | |
meeting of Governments next month will come up with tougher measures | :03:12. | :03:18. | |
against poaching. If you are asking your teacher to pass something, do | :03:18. | :03:26. | |
you say gizzit 'ere or, please give me it? A school has banned children | :03:26. | :03:31. | |
from saying certain phrases in Middlesbrougher. Nowt is no longer | :03:31. | :03:35. | |
allowed, and gizzit 'ere. The school says it is not trying to get | :03:35. | :03:39. | |
rid of the local accent, but wants to help the children speak English | :03:39. | :03:43. | |
properly, so they can be clearly understood. Here are some of the | :03:43. | :03:52. | |
pupils trying out the new rules. It's nowt. No, it's nothing. I've | :03:52. | :04:01. | |
done that. No, I have done it. say you don't know. | :04:01. | :04:08. | |
Lots of you have been in touch with comments on in. -- on this. Here | :04:08. | :04:18. | |

Finally, from banned words to banned kids - that is because an | :04:34. | :04:38. | |
airline has decided to ban children from some parts of the planes. Air | :04:39. | :04:44. | |
Asia is giving people the option to book a seat in a quiet zone where | :04:44. | :04:49. | |
no children under 12 will be allowed. Outrageous, isn't it? It | :04:49. | :04:53. |
