:00:00. > :00:14.I'm Ayshah with some cracking stories on the way.
:00:15. > :00:18.We have got some epic adventures, they go to some amazing places.

:00:33. > :00:35.First this morning, could this Saturn moon be the best
:00:36. > :00:43.The Cassini spacecraft has been looking at the moon,
:00:44. > :00:45.called Enceladus, which has an ocean under its icy surface.
:00:46. > :00:48.It's studied the jets of water blasting out and found
:00:49. > :00:52.that they contain most of the ingredients needed
:00:53. > :01:08.The new finding is finding hydrogen coming from the plume of Enceladus
:01:09. > :01:12.and seeing it could potentially support microbes on the floor of
:01:13. > :01:15.Enceladus. We now know it has almost all of the ingredients you would

:01:34. > :01:43.So give us a little bit of idea into Bill, the character,
:01:44. > :01:47.and what our audience can be expecting from the new assistant.
:01:48. > :01:50.I think Bill, she's great, man, she's really cool,
:01:51. > :01:53.she's very normal, very much like someone you'd bump
:01:54. > :01:59.She has a very direct way of looking at things, and she sort of,
:02:00. > :02:02.she asks The Doctor a lot of questions that haven't been asked
:02:03. > :02:04.Why do they keep saying "Exterminate"?
:02:05. > :02:10.Wouldn't it be quicker to just say "Kill"?
:02:11. > :02:12.Do we really want them to save time?!
:02:13. > :02:18.And what was it like going into the Tardis for the first time?
:02:19. > :02:22.It is genuinely bigger on the inside.
:02:23. > :02:26.There's so many things to play with, it's great.

:02:56. > :03:02.There are some in the middle and end of the series that
:03:03. > :03:06.There are some that you're in the scene and then
:03:07. > :03:09.they appear and you go, "Agh!"
:03:10. > :03:13.Which is good because that's what your character is supposed to do!
:03:14. > :03:16.Is it true that the Doctor is regenerating at the end of the year?
:03:17. > :03:19.Yes, yes, he is regenerating in the Christmas special.
:03:20. > :03:23.I'm just happy that I got to work with Peter,

:04:03. > :04:11.Jose Mourinho was not happy about drawing the game.
:04:12. > :04:20.If I was a Manchester United defender I would be very upset with
:04:21. > :04:21.the attacking players because they had to keep the game and they
:04:22. > :04:23.didn't. Now to a much chillier
