1
00:00:54,229 --> 00:00:51,750
this is the discovery of the first

2
00:00:56,389 --> 00:00:54,239
transiting circumbinary planet

3
00:00:58,069 --> 00:00:56,399
what that means is a circumbinary planet

4
00:01:00,470 --> 00:00:58,079
is a planet that goes around two stars

5
00:01:02,389 --> 00:01:00,480
at the same time and transit means it

6
00:01:06,230 --> 00:01:02,399
moves in front of the stars causing a

7
00:01:10,310 --> 00:01:08,230
multiple star systems

8
00:01:12,390 --> 00:01:10,320
people looking up at multiple sunsets

9
00:01:13,830 --> 00:01:12,400
and so on is a familiar theme from

10
00:01:15,749 --> 00:01:13,840
science fiction

11
00:01:17,590 --> 00:01:15,759
but this is the first time that it has

12
00:01:20,630 --> 00:01:17,600
become science fact

13
00:01:23,190 --> 00:01:20,640
so in some sense that star wars that

14
00:01:24,070 --> 00:01:23,200
sunset on tattooing that luke skywalker

15
00:01:26,710 --> 00:01:24,080
saw

16
00:01:29,670 --> 00:01:26,720
has become a possibility

17
00:01:33,910 --> 00:01:29,680
in some sense um the galaxy far far away

18
00:01:36,789 --> 00:01:35,590
well this is a very exciting discovery

19
00:01:38,390 --> 00:01:36,799
for me

20
00:01:40,310 --> 00:01:38,400
in part because i've been looking for

21
00:01:41,429 --> 00:01:40,320
circumbinary planets for over two

22
00:01:43,510 --> 00:01:41,439
decades

23
00:01:45,670 --> 00:01:43,520
but it doesn't feel like an ending it

24
00:01:47,510 --> 00:01:45,680
feels like a beginning because what it

25
00:01:49,270 --> 00:01:47,520
has done is opened up a whole new type

26
00:01:51,749 --> 00:01:49,280
of planetary system that can form in the

27
00:01:54,469 --> 00:01:51,759
galaxy there must be millions of these

28
00:01:56,069 --> 00:01:54,479
type of systems in the milky way galaxy

29
00:01:57,190 --> 00:01:56,079
there's a great moment in new hope where

30
00:02:00,950 --> 00:01:57,200
luke is

31
00:02:02,870 --> 00:02:00,960
watching a twin sunset on tatooine

32
00:02:05,030 --> 00:02:02,880
it's a it's a great way to show that

33
00:02:06,870 --> 00:02:05,040
we're not on earth that it's this exotic

34
00:02:08,790 --> 00:02:06,880
environment

35
00:02:10,790 --> 00:02:08,800
but that was never really thought to be

36
00:02:13,030 --> 00:02:10,800
possible and it's uh

37
00:02:15,670 --> 00:02:13,040
exciting to see that science is uh

38
00:02:21,030 --> 00:02:15,680
caught up with uh with the fantasy that

39
00:02:25,670 --> 00:02:22,710
the reality is often cooler than the

40
00:02:26,949 --> 00:02:25,680
fiction uh that

41
00:02:29,430 --> 00:02:26,959
you know when we see discoveries like

42
00:02:32,470 --> 00:02:29,440
this from kepler we see that that the

43
00:02:35,430 --> 00:02:32,480
universe is really a weird and exotic

44
00:02:38,229 --> 00:02:35,440
place and uh more so than a lot of the

45
00:02:39,670 --> 00:02:38,239
the depictions we make

46
00:02:41,430 --> 00:02:39,680
t-minus ten

47
00:02:42,470 --> 00:02:41,440
nine eight

48
00:02:43,509 --> 00:02:42,480
seven

49
00:02:44,630 --> 00:02:43,519
six

50
00:02:45,670 --> 00:02:44,640
five

51
00:02:46,710 --> 00:02:45,680
four

52
00:02:50,229 --> 00:02:46,720
three

53
00:02:52,949 --> 00:02:50,239
two engine start one zero and liftoff of

54
00:02:55,509 --> 00:02:52,959
the delta ii rocket with kepler on a

55
00:02:57,350 --> 00:02:55,519
search for planets in some way like our

56
00:02:59,110 --> 00:02:57,360
own burning our engine chamber pressures

57
00:03:04,229 --> 00:02:59,120
