1
00:00:13,749 --> 00:00:12,470
no matter how big your telescope is on

2
00:00:15,990 --> 00:00:13,759
the ground you just can't see through

3
00:00:17,750 --> 00:00:16,000
the air very well because the atmosphere

4
00:00:19,429 --> 00:00:17,760
is turbulent

5
00:00:21,429 --> 00:00:19,439
so even though you can see the stars

6
00:00:23,109 --> 00:00:21,439
with your eyes they're blurry they're

7
00:00:24,790 --> 00:00:23,119
twinkling they're doing things that you

8
00:00:26,870 --> 00:00:24,800
can't really compensate for yet from the

9
00:00:28,790 --> 00:00:26,880
ground so space telescope gives you a

10
00:00:31,670 --> 00:00:28,800
sharp image that you can't get from the

11
00:00:34,069 --> 00:00:31,680
ground

12
00:00:35,830 --> 00:00:34,079

13
00:00:37,350 --> 00:00:35,840
in astronomy there's what we knew before

14
00:00:40,150 --> 00:00:37,360
hubble and now there's what we know

15
00:00:41,910 --> 00:00:40,160
after hubble they're so different

16
00:00:43,990 --> 00:00:41,920
of course hubble has now had a life of

17
00:00:46,069 --> 00:00:44,000
30 years so this had a long time to make

18
00:00:48,389 --> 00:00:46,079
this revolution happen so it's not all

19
00:00:50,370 --> 00:00:48,399
at once it's a gradual revolution but

20
00:01:01,029 --> 00:00:50,380
it's still a huge revolution

21
00:01:02,470 --> 00:01:01,039

22
00:01:04,070 --> 00:01:02,480
i think the hubble telescope has been

23
00:01:05,990 --> 00:01:04,080
the most productive science instrument

24
00:01:08,149 --> 00:01:06,000
ever built

25
00:01:09,290 --> 00:01:08,159
so it is indeed the most astonishing
