00:00:20,230 --> 00:00:15,110
these beautiful colorful images that

3
00:00:24,390 --> 00:00:21,750
i love them they're colorful they're

4
00:00:30,550 --> 00:00:24,400
beautiful but they're signposts of star

5
00:00:34,150 --> 00:00:32,709
the reason these gas clouds are so

6
00:00:36,150 --> 00:00:34,160
colorful

7
00:00:38,630 --> 00:00:36,160
is that there are massive stars bigger

8
00:00:41,830 --> 00:00:38,640
than our sun that have recently formed

9
00:00:44,470 --> 00:00:41,840
recently in a in a cosmic sense

10
00:00:47,029 --> 00:00:44,480
but perhaps within the last million

11
00:00:49,350 --> 00:00:47,039
years or so these stars have coalesced

12
00:00:51,510 --> 00:00:49,360
and their radiation is so powerful that

13
00:00:59,110 --> 00:00:51,520
it goes out and ionizes the surrounding

14
00:01:03,430 --> 00:01:00,950
so astronomers see these colorful

15
00:01:05,350 --> 00:01:03,440
nebulae such that hubble reveals in

16
00:01:07,590 --> 00:01:05,360
great detail and we say oh that's

17
00:01:09,670 --> 00:01:07,600
beautiful but we also say aha that's a

18
00:01:11,750 --> 00:01:09,680
sign that star formation is still active

19
00:01:14,469 --> 00:01:11,760
in this region we can hone in with

20
00:01:16,149 --> 00:01:14,479
hubble and other telescopes and see

21
00:01:18,550 --> 00:01:16,159
exactly what's going on in the

22
00:01:19,749 --> 00:01:18,560
continuation of star formation in these

23
00:01:21,590 --> 00:01:19,759
regions

24
00:01:23,749 --> 00:01:21,600
we didn't really realize when hubble was

25
00:01:25,830 --> 00:01:23,759
launched that we could see such details

26
00:01:28,149 --> 00:01:25,840
about the dynamics of continuing star

27
00:01:29,670 --> 00:01:28,159
formation and that's something that now

28
00:01:31,590 --> 00:01:29,680
people love hubble for are these

29
00:01:41,310 --> 00:01:31,600
beautiful images of activity in our
