:00:00. > :00:00.Martin here, live with the kids who dug up this amazing ancient
:00:00. > :00:11.We explain how to catch a comet with a space probe.
:00:12. > :00:18.First up, space history has been made today
:00:19. > :00:21.after special probe Rosetta finally caught up with a comet it's been
:00:22. > :00:27.Since we told you about it this morning the craft has become the
:00:28. > :00:32.And despite the celebrations back here on earth this is just
:00:33. > :00:41.Earlier today the Rosetta space craft began to orbit this comet.
:00:42. > :00:44.It's going to spend the next year studying it.
:00:45. > :00:46.Its mission is to find out whether comets kickstarted life
:00:47. > :00:54.Comets scattered across earth 4.5 billion years ago, bringing with
:00:55. > :00:58.them water and possibly some of the ingredients for life.
:00:59. > :01:02.Scientists believe those ingredients mixed to create the chemicals
:01:03. > :01:21.The biggest question we are trying to cancer is where it did like come
:01:22. > :01:29.from? -- trying to cancer. Rosetta will spend the next few
:01:30. > :01:31.months taking measurements In November scientists plan to land
:01:32. > :01:34.a probe on the comet to see what it's made of
:01:35. > :01:38.and find out whether comets do hold task, so Newsround got astrophysics
:01:39. > :01:44.professor Tim O'Brien to tell you how it works...using a grape and an
:01:45. > :01:54.orange! This is supposed to be the Comet and
:01:55. > :02:00.this is the spacecraft. They are flying through space at amazing
:02:01. > :02:05.speeds and they are trying to fly along together. The spacecraft goes
:02:06. > :02:09.into orbit so in November, then it has mapped out the surface of the
:02:10. > :02:15.Comet, we will send a lander on the spacecraft and that will drop onto
:02:16. > :02:21.the Comet and it will screw itself in and it will take a ride into the
:02:22. > :02:25.inner solar system. We will see images coming back and it is really
:02:26. > :02:28.fantastic. Now, finding buried treasure might
:02:29. > :02:30.sound like something out of the movies but that's exactly
:02:31. > :02:33.what happened to Joseph, Aidan, The boys found a 4000-year-old
:02:34. > :02:37.golden ornament at an old burial It's believed to be an ancient hair
:02:38. > :02:54.clip from around 2,300 BC, Experts say it is priceless. Thank
:02:55. > :03:02.you for coming in. Tell us what it was like. It was really good. We had
:03:03. > :03:10.in digging and when we founded it was amazing. It is hard to describe
:03:11. > :03:19.how you felt. When did you realise it was something that was worth
:03:20. > :03:25.money? When we found out it was gold, they thought it was plastic
:03:26. > :03:31.but when we found out it was gold, we found out it was worth a lot of
:03:32. > :03:39.money. Are you going to be rich now? We are not! It is hopefully going to
:03:40. > :03:50.a special museum in Newcastle and it will join other pieces of interest
:03:51. > :04:00.there. There was another hair clip that was dug up. The other person, a
:04:01. > :04:09.man Jozsef Alderson, he is a family relation. It is strange, because he
:04:10. > :04:16.said they had not enriched their day, but he said we will leave the
:04:17. > :04:22.rest for future generations and then it happened to be his own family
:04:23. > :04:33.that found the other bed! -- that found the other piece. That is
:04:34. > :04:42.amazing. You were on a special bake when you found it so do you have any
:04:43. > :04:45.tips or viewers out there? If you are digging, it just brush the Earth
:04:46. > :04:59.lightly. Look curtly.
