:00:00. > :00:00.Hi, I'm Martin, with a really exciting Newsround today!
:00:07. > :00:12.The world gets ready for today's solar eclipse.
:00:13. > :00:17.But if you're watching, there is a safety warning!
:00:18. > :00:24.I have got my solar viewing glasses so that I'd do not burn my eyes and
:00:25. > :00:32.so does Mr Bath. There are less than four hours
:00:33. > :00:36.before people in America get to see The sun will be completely
:00:37. > :00:41.blocked by the moon It'll feel like the
:00:42. > :00:44.middle of the night. It's the first coast-to-coast total
:00:45. > :00:48.solar eclipse in 99 years. Space experts at NASA say it's
:00:49. > :00:55.going to be amazing. This will be
:00:56. > :00:58.a once-in-a-lifetime event. There's an eclipse of the Sun that's
:00:59. > :01:01.going to go all the way across the United States,
:01:02. > :01:03.and that hasn't So the moon is going to actually
:01:04. > :01:08.move in front of the Sun and cast And that shadow will be
:01:09. > :01:13.about a 70-mile strip of total darkness that will go
:01:14. > :01:15.across the United States. But even if you're not in that
:01:16. > :01:17.narrow strip, everyone in the United States can see
:01:18. > :01:20.a partial eclipse, at least. I think they're the most beautiful
:01:21. > :01:23.things you can see in the sky. When you see the entirely eclipsed
:01:24. > :01:27.Sun, when the moon is merely -- entirely covering up the Sun,
:01:28. > :01:29.it looks like the sky You see the stars out
:01:30. > :01:33.during the day, you see Let's cross live now
:01:34. > :01:37.to our reporter, Nada Tawfik. How are the excitement
:01:38. > :01:50.levels over there, Nada? Well, everyone here is just
:01:51. > :01:55.overjoyed and all that anyone can talk about is how they will feel in
:01:56. > :01:58.that big moment. The small town has been designated by Nasa as a point
:01:59. > :02:02.of greatest eclipse. It will have the best view of the big show from
:02:03. > :02:04.here, and the town has been preparing for years to make
:02:05. > :02:09.preparations and get everyone in place from all across the world who
:02:10. > :02:13.have travelled here. They have even considered this a holiday, closing
:02:14. > :02:17.schools. Here are some of the students and children who took the
:02:18. > :02:21.day off for the big event. How excited are you? I am pretty
:02:22. > :02:26.excited, this is a once-in-a-lifetime event. And is it
:02:27. > :02:32.something that you anticipated or experienced before in the small
:02:33. > :02:38.town? No, it has not. How excited I you? I am very excited to see it
:02:39. > :02:43.from the best totality on the world. Institute known about the solar
:02:44. > :02:48.eclipse before in school? Yes. What did they tell you? Well, I know that
:02:49. > :02:53.the next total eclipse will not be in decades. Yes, it you a young so a
:02:54. > :02:54.lot of people have the weight-bearing tire lives to
:02:55. > :03:05.experience a total eclipse, you lucky? Yes. We are pretty lucky. Who
:03:06. > :03:09.are you here with? No. Are you here with your family? The school? And
:03:10. > :03:17.how excited are you, how old are you? A little camera shy! Have you
:03:18. > :03:23.guys got an assignment from your school after this? I have not yet.
:03:24. > :03:24.So you will be able to enjoy it and Nasa will be live streaming. Thank
:03:25. > :03:27.you very much. We've been following a group
:03:28. > :03:30.of British Scouts on their journey I've got my sun-viewing glasses,
:03:31. > :03:37.so that I don't burn my eyes, These Scouts have arrived
:03:38. > :03:42.in Yellowstone National Park, in America, to some
:03:43. > :03:47.incredible views. They've travelled all the way
:03:48. > :03:49.from Salisbury and are so excited They're getting ready for the total
:03:50. > :03:55.solar eclipse and have been practising safe ways to view it
:03:56. > :04:02.without looking directly at the Sun. We need to make sure we're safe,
:04:03. > :04:09.so what I need to make sure is that we never,
:04:10. > :04:11.ever view the Sun through binoculars And also, never look
:04:12. > :04:15.at the Sun with your bare eyes That gong comes from this
:04:16. > :04:26.tall fella, Big Ben. But today's midday bongs
:04:27. > :04:30.were the last for around four years because London's famous clock
:04:31. > :04:31.tower needs repairs. Although it will still chime
:04:32. > :04:39.on special occasions, There were cheers from crowds
:04:40. > :04:42.when when the final Strictly Come Dancing
:04:43. > :04:47.starts again next month, and the final contestants
:04:48. > :04:52.are announced tonight. So far, we know stars including
:04:53. > :04:56.Mollie King from the Saturdays, and CBBC presenter Susan
:04:57. > :05:04.Calman are taking part. # Dibby, dibby, dibby,
