:00:10. > :00:15.First, to an exciting space discovery -
:00:16. > :00:18.scientists say they've spotted jets of water
:00:19. > :00:21.on one of the moons circling the planet Jupiter.
:00:22. > :00:25.sent back from Nasa's Hubble telescope,
:00:26. > :00:28.show what experts reckon is water spurting out
:00:29. > :00:31.from the moon's huge ocean under the surface.
:00:32. > :00:38.there's a chance of finding basic forms of life.
:00:39. > :00:40.I'm almost sure there is life of some kind
:00:41. > :00:45.I'd be flabbergasted if there wasn't.
:00:46. > :00:51.I think that the conditions seem to be right in a number of places.
:00:52. > :00:56.I'm almost certain bacteria of some kind must be able to form
:00:57. > :01:02.in the liquid water oceans on some of the moons of Jupiter and Saturn.
:01:03. > :01:05.From a Jupiter moon to a Northampton star -
:01:06. > :01:08.15-year-old swimmer Ellie Robinson stormed to gold
:01:09. > :01:11.at the Paralympic Games in Rio earlier this month,
:01:12. > :01:14.and yesterday was her first day back at school,
:01:15. > :01:21.To the world, she's a Paralympic champion but, to her friends,
:01:22. > :01:25.she's just Ellie, the same 15-year-old schoolmate,
:01:26. > :01:31.I've been waiting to see these guys for ages,
:01:32. > :01:34.and it's so nice being back, talking to them.
:01:35. > :01:36.We're not even talking about Rio, to be honest!
:01:37. > :01:38.It's Ellie's first day back at school,
:01:39. > :01:41.and the reaction was just a little bit noisy.
:01:42. > :01:45.to the new Paralympic star of the pool,
:01:46. > :01:50.when they watched back her record-breaking race.
:01:51. > :01:54.suggests she still can't quite believe it all happened.
:01:55. > :01:56.It was really strange, because I remember I kept turning around
:01:57. > :01:59.and checking the scoreboard, just in case I'd read it wrong,
:02:00. > :02:01.because I didn't want to be like, "Yeah!"
:02:02. > :02:03.And then like, "Oh, no, I got silver."
:02:04. > :02:05.Well, it doesn't mean any more than just having
:02:06. > :02:08.one of my best friends back at school, someone to talk to.
:02:09. > :02:11.We're all really proud of Ellie and what she's done.
:02:12. > :02:17.It's quite nice seeing everyone come back together,
:02:18. > :02:20.It's like kind of united us, and it's really nice.
:02:21. > :02:28.So special assembly over, time for an extra special cake.
:02:29. > :02:33.but today was about celebrations, not exams,
:02:34. > :02:39.and her mates all seem to have perfected the Ellie pose.
:02:40. > :02:42.Next, millions of Americans were up late last night
:02:43. > :02:46.to watch these two people go head to head in a TV debate.
:02:47. > :02:49.Both Donald Trump and Hilary Clinton want to become
:02:50. > :02:52.the President of the United States of America -
:02:53. > :02:54.one of the biggest jobs in the world.
:02:55. > :02:57.The two candiates spoke about how they could make the country better,
:02:58. > :03:00.but they also argued quite a lot too.
:03:01. > :03:03.Donald, I know that you live in your own reality,
:03:04. > :03:13.I said, "There's a person with a temperament that got a problem."
:03:14. > :03:30.You can go to Newsround online for more on Hillary Clinton and Donald
:03:31. > :03:32.Trump. the endangered animal
:03:33. > :03:35.that you've probably never heard of. World leaders are discussing
:03:36. > :03:37.how to help save it Here's Naz with what you need
:03:38. > :03:41.to know about pangolins. Move over pandas, there's another
:03:42. > :03:44.cute animal in town - the pangolin. because they're mainly
:03:45. > :03:49.found in Africa and Asia, at being a super hero,
:03:50. > :04:00.it's a pangolin. Its body is covered in scales
:04:01. > :04:03.so sharp it could cut you. These awesome animals can kick up
:04:04. > :04:06.a stink where ever they go. No, really - they make a huge stink
:04:07. > :04:12.to scare off predators. And their tongue can be
:04:13. > :04:15.as long as their bodies. And like every super
:04:16. > :04:22.hero, it has a weakness, They curl up into balls
:04:23. > :04:29.when they're afraid, and then the humans go
:04:30. > :04:32.and pick them up. OK, maybe they won't be great super
:04:33. > :04:36.heroes, but they are under threat and are the most poached animal
:04:37. > :04:42.in the world. Their scales are made from keratin -
:04:43. > :04:46.the same thing as rhino horns - and that's what hunters want to sell
:04:47. > :04:55.to make lots of money. That's all from me, Newsround's back
:04:56. > :04:59.right here in about half an hour.
