1
00:00:07,960 --> 00:00:06,190
Voyager 1 is in a place no spacecraft

2
00:00:10,180 --> 00:00:07,970
has ever been before we are in the very

3
00:00:11,919 --> 00:00:10,190
outer edge of the heliosphere one

4
00:00:14,650 --> 00:00:11,929
magnetic field lines which act like a

5
00:00:16,330 --> 00:00:14,660
huge highway so that all the particles

6
00:00:18,790 --> 00:00:16,340
that were inside the heliosphere have

7
00:00:20,980 --> 00:00:18,800
streamed away and are now gone and what

8
00:00:23,110 --> 00:00:20,990
we see instead are the cosmic rays from

9
00:00:25,110 --> 00:00:23,120
the outside interstellar space which

10
00:00:28,180 --> 00:00:25,120
have streamed back in to replace them

11
00:00:29,890 --> 00:00:28,190
for the last seven years Voyager 1 has

12
00:00:31,960 --> 00:00:29,900
been in a region of the outer

13
00:00:34,060 --> 00:00:31,970
heliosphere where it's surrounded by PI

14
00:00:35,950 --> 00:00:34,070
ins moving at about a few percent the

15
00:00:38,619 --> 00:00:35,960
speed of light those ions were

16
00:00:41,319 --> 00:00:38,629
accelerated in this region and are

17
00:00:44,110 --> 00:00:41,329
moving uniformly in all directions as

18
00:00:46,299 --> 00:00:44,120
Voyager 1 continued though it began to

19
00:00:48,759 --> 00:00:46,309
see a change in that distribution and

20
00:00:51,549 --> 00:00:48,769
entered a magnetic highway where all the

21
00:00:53,950 --> 00:00:51,559
pink colored ions were leaving the

22
00:00:56,500 --> 00:00:53,960
heliosphere along the magnetic field and

23
00:00:58,119 --> 00:00:56,510
at the same time they blew ions which

24
00:01:00,430 --> 00:00:58,129
are the cosmic rays particles moving

25
00:01:03,430 --> 00:01:00,440
with a higher speed started coming in

26
00:01:05,170 --> 00:01:03,440
from interstellar space Voyager 1 is now

27
00:01:07,959 --> 00:01:05,180
in a region where it's surrounded only
