Hey, everyone. | 0:00:10 | 0:00:11 | |
Martin here with the big stories this Wednesday. | 0:00:11 | 0:00:14 | |
First, the world's longest and deepest train tunnel has | 0:00:14 | 0:00:17 | |
officially opened in Switzerland. | 0:00:17 | 0:00:19 | |
It's taken 17 years to build the Gotthard tunnel, which goes | 0:00:19 | 0:00:22 | |
for 57 kilometres under the Alps. | 0:00:22 | 0:00:25 | |
And today, fireworks greeted the first trains. | 0:00:25 | 0:00:29 | |
The tunnel gives a high-speed rail link between Northern | 0:00:29 | 0:00:31 | |
and Southern Europe. | 0:00:31 | 0:00:32 | |
It's more than two kilometres under the mountains at its deepest point. | 0:00:32 | 0:00:38 | |
Now to something else that's massive - | 0:00:38 | 0:00:40 | |
the Square Kilometre Array project. | 0:00:40 | 0:00:41 | |
When it's finished, the radio telescope will be the most powerful | 0:00:41 | 0:00:44 | |
in the world and be able to search further into space than ever before. | 0:00:44 | 0:00:47 | |
And there's one big question scientists hope it will | 0:00:47 | 0:00:49 | |
help us answer. | 0:00:49 | 0:00:50 | |
Here's Ayshah. | 0:00:50 | 0:00:55 | |
Aliens. | 0:01:04 | 0:01:09 | |
Are they really out there? | 0:01:09 | 0:01:13 | |
And, if so, are we ever going to find them? | 0:01:13 | 0:01:17 | |
The universe is vast. | 0:01:17 | 0:01:20 | |
Our solar system is one of the solar systems around a sun, | 0:01:20 | 0:01:24 | |
which is one of the millions of stars in our galaxy. | 0:01:24 | 0:01:28 | |
Our galaxy is one among the millions of galaxies | 0:01:28 | 0:01:30 | |
in the universe. | 0:01:30 | 0:01:31 | |
So, why not? | 0:01:31 | 0:01:32 | |
Maybe there is life somewhere in another solar | 0:01:32 | 0:01:34 | |
system in another galaxy. | 0:01:34 | 0:01:39 | |
That is what scientists are trying to find out | 0:01:39 | 0:01:41 | |
with the help of these. | 0:01:41 | 0:01:44 | |
This is the Square Kilometre Array project. | 0:01:44 | 0:01:46 | |
When it is finished, it will be the world's most | 0:01:46 | 0:01:50 | |
powerful radio telescope, so sensitive that it will be able | 0:01:50 | 0:01:52 | |
to detect a signal from a planet that is tens of light years away. | 0:01:52 | 0:01:58 | |
These telescopes are listening for intelligent life | 0:01:58 | 0:02:01 | |
and that is why they have decided to build them here. | 0:02:01 | 0:02:05 | |
What makes this place in South Africa perfect | 0:02:05 | 0:02:07 | |
is that there is no radio waves around to mess up the signal. | 0:02:07 | 0:02:10 | |
That's no microwaves, no mobile phones - | 0:02:10 | 0:02:15 | |
I've had to turn mine off. | 0:02:15 | 0:02:17 | |
Every day, these dishes are collecting massive amounts | 0:02:17 | 0:02:21 | |
of data, which will eventually be processed by a supercomputer | 0:02:21 | 0:02:23 | |
in the UK where experts will look for any signs of life. | 0:02:23 | 0:02:30 | |
How do you go about looking for alien signals? | 0:02:30 | 0:02:33 | |
Well, you have got big telescopes like that and they can go listen | 0:02:33 | 0:02:38 | |
in the universe and listen for radio signals from other planets | 0:02:38 | 0:02:42 | |
where we hope they also have radio signals and maybe we can detect | 0:02:42 | 0:02:45 | |
some of these signals. | 0:02:45 | 0:02:46 | |
How would we know that an alien has tried to contact us? | 0:02:46 | 0:02:50 | |
We are looking for intelligent signals, signals that are not | 0:02:50 | 0:02:52 | |
from nature but that are made by intelligent creatures. | 0:02:52 | 0:02:59 | |
Will we ever be able to find an alien? | 0:02:59 | 0:03:01 | |
I certainly hope so. | 0:03:01 | 0:03:02 | |
I hope to find them once in my lifetime. | 0:03:02 | 0:03:04 | |
It would be such a big discovery. | 0:03:04 | 0:03:06 | |
But it could be very long and it could also take very long | 0:03:06 | 0:03:09 | |
to communicate with them because the signals take maybe years | 0:03:09 | 0:03:11 | |
to go to the civilisation and also take years to get back, | 0:03:11 | 0:03:14 | |
so one simple question and answer could take, like, 40 years. | 0:03:14 | 0:03:18 | |
Of course, there's no guarantee that other civilisations exist | 0:03:18 | 0:03:22 | |
beyond our world, but, if they do, it might not be long before | 0:03:22 | 0:03:24 | |
SKA finds them. | 0:03:24 | 0:03:30 | |
From searching for aliens to searching for pop stars - | 0:03:31 | 0:03:34 | |
X Factor bosses have just announced this year's "new" judging line-up, | 0:03:34 | 0:03:38 | |
which they hope will help save the show from years | 0:03:38 | 0:03:41 | |
of falling ratings. | 0:03:41 | 0:03:42 | |
Ricky's got this. | 0:03:42 | 0:03:44 | |
The all-new X Factor is actually... | 0:03:44 | 0:03:46 | |
pretty old. | 0:03:46 | 0:03:53 | |
Faces from the past are returning to search for a new star. | 0:03:53 | 0:03:58 | |
Louis Walsh, Sharon Osbourne and Nicole Scherzinger | 0:03:58 | 0:03:59 | |
rejoin Simon Cowell. | 0:03:59 | 0:04:02 | |
Don't forget, Dermot's back, too. | 0:04:02 | 0:04:05 | |
To be honest, it feels like we've gone back in time to the old school. | 0:04:05 | 0:04:11 | |
That's because all these judges have featured on the show before. | 0:04:11 | 0:04:15 | |
Sharon and Louis launched a series more than ten years ago and singer | 0:04:15 | 0:04:18 | |
Nicole became a judge in 2012. | 0:04:18 | 0:04:24 | |
Today, ITV released this pic to get us all excited about the new series. | 0:04:24 | 0:04:31 | |
Yep, that's four chairs with the names on the back. | 0:04:31 | 0:04:33 | |
I'm sure you can all hardly contain your excitement. | 0:04:33 | 0:04:38 | |
So can these familiar faces bring back a bit of familiar sparkle | 0:04:38 | 0:04:41 | |
to The X Factor? | 0:04:41 | 0:04:43 | |
And you can tell us what you think about this year's line-up over | 0:04:43 | 0:04:46 | |
at Newsround online. | 0:04:46 | 0:04:48 | |
That's all from the TV team today. | 0:04:48 | 0:04:49 | |
Ayshah's back tomorrow morning. | 0:04:49 | 0:04:51 | |
See ya! | 0:04:51 | 0:04:57 |
