:00:17. > :00:22.Hello and welcome to Newsround, with Hayley and Joe. We have got a
:00:22. > :00:25.tasty Tuesday fall of Newsroundy treats for you. Coming up:
:00:25. > :00:30.We will find out about the major operation to rescue stranded seals.
:00:30. > :00:34.And the bomb blast that has devastated lives in Afghanistan.
:00:34. > :00:38.But first to some exciting news about space. The final frontier! A
:00:38. > :00:41.new planet has been found outside our solar system that is so similar
:00:41. > :00:43.to ours that scientists are calling it Earth's twin. Scientists at NASA
:00:43. > :00:47.are getting very excited about it because they reckon it could
:00:47. > :00:54.actually support life. But don't pack your bags yet, Hayley, because
:00:54. > :00:58.if you think Mars is a bit of a trek, this is 600 light years away!
:00:59. > :01:03.They call it Kepler-22b. It's more than twice the size of Earth, and
:01:03. > :01:05.has a nice, cosy temperature of 22 Celsius. And in an enormous,
:01:05. > :01:12.constantly moving universe made up of fireballs and ice planets,
:01:12. > :01:17.finding a place that is similar to the Earth is pretty special. And
:01:17. > :01:20.this is why. Here is us - Earth. We orbit the Sun from about 90 million
:01:20. > :01:26.miles away, close enough to keep warm and not too close to evaporate
:01:26. > :01:30.all of our precious water. This is Kepler-22b. As you can see, it also
:01:30. > :01:38.orbits its sun at about the same distance away. It is this area that
:01:38. > :01:40.they call the Goldilocks zone - not too hot, not too cold, just right.
:01:40. > :01:45.Since launching their Kepler telescope into space two years ago,
:01:45. > :01:49.NASA has been searching for planets like this. They have found more
:01:49. > :01:52.than a thousand new worlds since then, but this is the first where
:01:52. > :01:57.conditions are most like Earth. But there is a lot they still don't
:01:57. > :02:01.know. Is it rocky on Kepler-22b or gassy? Could it be made up of
:02:01. > :02:07.liquid? And if it is 600 light years away, how on Earth are we
:02:07. > :02:11.going to get there? So many questions! Well, if anyone
:02:11. > :02:15.knows the answers, it is probably space supremo Professor Brian Cox.
:02:15. > :02:24.Yeah, but we could never get hold of him, could we? We could, and we
:02:24. > :02:30.did! Kepler is a long way away. Could we
:02:30. > :02:33.ever get there? Yes, it is in principle possible. Even if you
:02:33. > :02:37.think something is one light year away because you are very close,
:02:37. > :02:40.you might think you could any travel -- if you could only travel
:02:40. > :02:43.at the speed of light, it would take a year to get there. But
:02:43. > :02:47.Einstein tells us that strange things happen when you approach the
:02:47. > :02:51.speed of light. The closer you get to it, the more your time it slows
:02:51. > :02:55.down, or distances shrink. So if you were Arabian of light, you
:02:55. > :02:59.would jump across the universe instantaneously. We could not do it
:02:59. > :03:03.in modern spaceships, though. is the trouble, it is an
:03:03. > :03:08.engineering problem. They have called it Kepler-22b, not very
:03:08. > :03:13.catchy. Why? It is named after the Kepler mission. Kepler was the guy
:03:13. > :03:17.who first understood planetary orbits. All day, we have been
:03:17. > :03:23.asking the guys on the website to send in their ideas for a planet.
:03:23. > :03:28.What would you call a planet? one, you could call it Earth
:03:28. > :03:34.version 2.0, because it could be very similar to the earth. Let's
:03:34. > :03:38.call it Earth to. Catchy. Not very catchy, is it?
:03:38. > :03:48.You have been getting in touch all day with your suggestions for the
:03:48. > :03:56.
:03:56. > :03:59.Now to a big rescue operation for hundreds of stranded seals off the
:03:59. > :04:02.coast of Lincolnshire. The pups were separated from their mothers
:04:02. > :04:05.by big waves. The extra high tide struck the seal colony at Donna
:04:05. > :04:10.Nook a week ago, and it is estimated that up to 75 seal pups
:04:10. > :04:20.may have died. It is a known seal sanctuary, and visitors to the area
:04:20. > :04:25.have been shocked by the news. really sad, because it is an
:04:25. > :04:29.amazing sight to see. It is quite a shock, because there was a thriving
:04:30. > :04:32.community. The first time we came, 600 pups were born.
:04:32. > :04:35.Next to Afghanistan, where a suicide bomb has killed more than
:04:35. > :04:38.50 people. The bomb exploded when people were celebrating a religious
:04:38. > :04:41.festival in the capital, Kabul. It comes just a day after big talks
:04:41. > :04:46.took place between Britain and other countries, aimed at securing
:04:46. > :04:48.a safe future for people in the country. But now that has been
:04:48. > :04:58.thrown into doubt. The centre of Kabul in the
:04:58. > :04:58.
:04:58. > :05:02.aftermath of one of the biggest attacks in the city's history.
:05:02. > :05:05.Hours earlier, people were celebrating a special festival for
:05:05. > :05:08.Shiite Muslims. Tensions exist in Afghanistan between Shiites and
:05:08. > :05:11.other Muslims called Sunnis, but there has not been an attack of
:05:11. > :05:15.this scale in the country since the fall of the terrorist group the
:05:16. > :05:18.Taliban ten years ago. This bombing was different to most of the recent
:05:18. > :05:23.violence in Afghanistan, which has been aimed at the foreign troops
:05:23. > :05:29.there. Doctors, nurses and the police struggled to count the
:05:29. > :05:35.number of dead and injured. One bystander had this to say - a "this
:05:35. > :05:38.action is against humanity and against Islam". Afghanistan's
:05:38. > :05:40.President spoke about the attack while attending a set of talks in
:05:40. > :05:46.Germany with other world leaders about how Afghanistan will be run
:05:46. > :05:49.after foreign troops leave in three years' time. This is the first time
:05:49. > :05:56.on such an important religious day in Afghanistan that terrorism of
:05:56. > :06:01.that horrible nature is taking place. World leaders are still
:06:01. > :06:07.trying to secure peace and progress for the future of Afghanistan. But
:06:07. > :06:11.for the people here now, it is hard to look beyond today.
:06:11. > :06:14.Sport, and it's crunch-time tonight for this guy. Chelsea manager Andre
:06:14. > :06:19.Villas-Boas needs his under-fire team to either win or draw 0-0 to
:06:19. > :06:24.progress in the Champions League. They play Valencia at Stamford
:06:24. > :06:31.Bridge. And even though the Blues are going through a bad run at the
:06:31. > :06:34.moment, the manager says he has no intention of changing his tactics.
:06:34. > :06:39.We will not change our strategy just because we are playing such an
:06:39. > :06:43.important game. The strategy will be the same. We will take the
:06:43. > :06:46.initiative with the ball. We do not speculate with the game.
:06:46. > :06:50.What next for David Beckham? Goldenballs has one more game for
:06:50. > :06:53.LA Galaxy before his contract ends. He says he's not sure if he'll stay
:06:53. > :07:00.in America or play at the 2012 Olympics, but don't worry, Becks
:07:00. > :07:03.fans - he says he has no intention of retiring.
:07:03. > :07:08.Hot on the heels of Newsround's autism special, there is another
:07:08. > :07:12.one on the way tonight on the CBBC channel tonight at 6:20pm. It is
:07:12. > :07:22.about two kids who live different lives, but who spend a week in each
:07:22. > :07:28.
:07:28. > :07:35.Before we go, imagine opening your lunchbox and finding a two-year-old
:07:35. > :07:38.sandwich inside. How gross would that be? Ugh! Well, a sandwich
:07:38. > :07:41.which stays fresh for two years has been developed for the US army.
