1
00:00:07,240 --> 00:00:12,560
Something is stirring on the face
of our nearest star.


2
00:00:12,560 --> 00:00:15,720
Something powerful and unsettling.


3
00:00:17,360 --> 00:00:19,480
Because the sun is becoming
more active


4
00:00:19,480 --> 00:00:21,800
it will have an impact in the lives
of millions of people.


5
00:00:24,560 --> 00:00:28,480
To understand what's
coming our way,


6
00:00:28,480 --> 00:00:31,640
they are doing something we cannot,


7
00:00:31,640 --> 00:00:34,200
stare directly into the sun.


8
00:00:34,200 --> 00:00:36,520
If the sun keeps
carrying on like this,


9
00:00:36,520 --> 00:00:39,840
we could be in for some really big
storms over the next 12 months.


10
00:00:43,000 --> 00:00:45,960
What they are expecting in
the next year


11
00:00:45,960 --> 00:00:50,200
are colossal eruptions from the sun


12
00:00:50,200 --> 00:00:54,440
that fling billions of tonnes of
plasma towards our planet.


13
00:00:57,800 --> 00:01:02,720
Our hi-tech society has never been
so vulnerable,


14
00:01:02,720 --> 00:01:04,680
for when a solar storm strikes,


15
00:01:10,960 --> 00:01:13,240
it could shut us down.


16
00:01:17,040 --> 00:01:20,160
If we don't understand space
weather more clearly


17
00:01:20,160 --> 00:01:23,560
we could easily end up
in the electronic dark ages.


18
00:01:23,560 --> 00:01:28,040
We are playing a game of Russian
roulette with the sun.


19
00:01:28,040 --> 00:01:31,520
If we play that game long enough,
we will lose.


20
00:01:59,360 --> 00:02:02,560
We all worry about the weather,


21
00:02:04,680 --> 00:02:08,160
but now there is a new
kind of weather to worry about.


22
00:02:10,720 --> 00:02:14,560
This weather comes not from
over the horizon,


23
00:02:14,560 --> 00:02:17,600
but from 93 million miles beyond it.


24
00:02:31,560 --> 00:02:34,560
'Winds blowing once again...


25
00:02:36,600 --> 00:02:40,120
'..But we still enjoy the clear sky
and bright sunshine during the day


26
00:02:40,120 --> 00:02:45,680
'so we should be bright,
dry and quiet in the middle
and latter portion of the week.'


27
00:02:47,160 --> 00:02:51,320
Outer space is about to get a whole
lot closer to home.


28
00:03:11,120 --> 00:03:13,840
The giver of life, light and heat,


29
00:03:13,840 --> 00:03:16,360
that looks so placid,
is anything but.


30
00:03:27,920 --> 00:03:30,800
When violence erupts on its surface,


31
00:03:37,280 --> 00:03:41,560
it has the power to bring our modern
life to a standstill.


32
00:03:46,240 --> 00:03:50,720
This power was demonstrated
to the world in 1989.


33
00:03:50,720 --> 00:03:52,560
The target, Quebec.


34
00:03:53,560 --> 00:03:58,200
Well, in 1989 there was a storm
where we saw for real


35
00:03:58,200 --> 00:04:01,600
how serious these problems
could be.


36
00:04:01,600 --> 00:04:03,600
What happened was the solar storm


37
00:04:03,600 --> 00:04:05,760
changed the magnetic field
of the Earth.


38
00:04:05,760 --> 00:04:08,320
This caused currents to be
induced in the ground,


39
00:04:08,320 --> 00:04:11,120
and those currents overloaded
a power station.


40
00:04:14,360 --> 00:04:16,720
'There has been a big power failure
in Quebec.


41
00:04:16,720 --> 00:04:20,640
'Most of the province is in darkness,
