:00:00. > :00:12.Hi guys, Ayshah here with a daredevil diver and exciting space
:00:13. > :00:15.discovery on the way! But first to Ukraine where all sorts
:00:16. > :00:19.has been happening today. In the last few hours America's warned
:00:20. > :00:22.Russia not to do anything that could increase tensions in the country. It
:00:23. > :00:24.comes after Russia put its military on stand-by, armed men took control
:00:25. > :00:30.of a government building and trouble spread from Kiev.
:00:31. > :00:39.This is Kiev, Ukraine's capital city. Days after the protesters won
:00:40. > :00:42.their battle the streets are quiet. In the beginning this was about
:00:43. > :00:46.whether Ukraine's people wanted to be closer to Russia or the rest of
:00:47. > :00:51.Europe. But after days of violence the problems are becoming more
:00:52. > :00:54.complicated. Former President Viktor Yanukovych - who disappeared after
:00:55. > :00:58.being forced from power last week - turned up in Russia's capital city,
:00:59. > :01:02.Moscow. He says he's still Ukraine's president. Meanwhile, the government
:01:03. > :01:07.that replaced him is struggling to keep any kind of control, and there
:01:08. > :01:22.are no police on the streets to keep order. People are still concerned.
:01:23. > :01:28.Especially about the economy. Could it split in two? And there are now
:01:29. > :01:31.big problems in other parts of the country. This morning, armed men
:01:32. > :01:35.took control of government buildings in an area of Ukraine called Crimea.
:01:36. > :01:44.Many people in this part of Ukraine feel they are more Russian than
:01:45. > :01:50.Ukrainian. The Russian flag now flies above the parliament here.
:01:51. > :01:59.They're pushing through police lines. They're saying they've waited
:02:00. > :02:02.for this moment for 20 years. Today, things have got a lot more tense.
:02:03. > :02:06.The Russian President, Vladimir Putin has ordered fighter jets and
:02:07. > :02:09.150,000 troops to get ready. But the new Ukrainian president has warned
:02:10. > :02:13.Russia not to move troops from their bases. Britain, France and America
:02:14. > :02:16.say they are all worried about what's going on, because after
:02:17. > :02:20.what's happened today the chances of Ukraine staying united are getting
:02:21. > :02:23.worse. Space news and NASA's announced the
:02:24. > :02:26.discovery of 715 new planets from outside of our solar system. It's
:02:27. > :02:29.all part of the Kepler Telescope's hunt for earth-like planets that
:02:30. > :02:52.could support life. Scientists think four of them could have a chance.
:02:53. > :02:56.Finally, to the man planning to jump off Mount Everest in just a winged
:02:57. > :02:59.suit. Joby Ogwyn, here, has been preparing for the dive in May with a
:03:00. > :03:00.series of test jumps. He
