RADIO: We're panning southwest.

2
00:02:01,043 --> 00:02:04,043
We should be in a position to start
the survey in 20 minutes.

3
00:02:13,123 --> 00:02:16,723
So we had a tip off, a breakthrough
last night that there was an unusual

4
00:02:16,723 --> 00:02:19,323
transmission in the direction
of Voyager.

5
00:02:22,403 --> 00:02:25,043
<font color="

6
00:02:25,043 --> 00:02:28,323
But our team here picked up
multiple narrowband signals.

7
00:02:33,883 --> 00:02:36,483
I don't think we can discount
this being genuine.

8
00:03:15,883 --> 00:03:17,363
Extraterrestrial life,

9
00:03:17,363 --> 00:03:22,363
the scientific basis for
extraterrestrial life is so clear.

Department of Defence,

11
00:03:27,723 --> 00:03:32,083
unidentified aerial phenomenon,
which add fuel to the belief of

12
00:03:32,083 --> 00:03:33,963
some that we are not alone.

13
00:03:36,683 --> 00:03:41,163
It's looking like most stars
may, in fact, have planets.

14
00:03:41,163 --> 00:03:46,443
There may be a tremendous number
<font color="

15
00:03:46,443 --> 00:03:49,443
So you see this as a national
security issue?

16
00:03:49,443 --> 00:03:50,843
Absolutely.

17
00:03:50,843 --> 00:03:54,283
They're going to have to acknowledge
that there is something

18
00:03:54,283 --> 00:03:56,283
there we need to be concerned about.

19
00:03:58,083 --> 00:04:02,843
This is a goal of Nasa - to
<font color="

20
00:04:02,843 --> 00:04:05,483
and distribution of life
in the universe.

21
00:04:05,483 --> 00:04:11,043
It's very important that the facts
are heard and fully understood,

22
00:04:11,043 --> 00:04:15,403
and that this body is able to take
the appropriate decisions.

23
00:04:17,163 --> 00:04:19,203
If there is a signal out there,

24
00:04:19,203 --> 00:04:22,403
<font color="
and closer to it.

25
00:05:11,443 --> 00:05:16,363
First of all, your first concern
is, is the signal real? Right?

26
00:05:16,363 --> 00:05:20,243
Secondly, is it coming from the sky

27
00:05:20,243 --> 00:05:24,003
or coming from the local
environment?

28
00:05:27,003 --> 00:05:29,403
Does it have any information
content?

29
00:05:32,523 --> 00:05:35,003
<font color="

30
00:05:35,003 --> 00:05:37,603
And you just work
through a whole lot

31
00:05:37,603 --> 00:05:42,003
of different dependent questions.

32
00:05:44,363 --> 00:05:46,683
If nature doesn't give
you an explanation,

33
00:05:46,683 --> 00:05:50,643
then you have to be prepared
to think about non-natural,

34
00:05:50,643 --> 00:05:56,323
<font color="
civilisation explanations

35
00:05:56,323 --> 00:06:00,243
for the data.
You have to be open to that.

36
00:06:04,523 --> 00:06:06,963
If we do detect a signal
from somewhere and it looks

37
00:06:06,963 --> 00:06:12,283
like it's of intelligent origin,
what's going to happen is an alert

38
00:06:12,283 --> 00:06:15,363
<font color="
telescope in the world

39
00:06:15,363 --> 00:06:18,763
is going to turn to that location
and start gathering data.

40
00:06:57,803 --> 00:07:01,483
The transmission was picked
up at 8.4 megahertz, but extended

41
00:07:01,483 --> 00:07:05,723
analysis has shown it was sweeping
through multiple frequencies.

42
00:07:05,723 --> 00:07:10,403
<font color="
to give the details.

43
00:07:10,403 --> 00:07:14,683
So our main interest is the power
required to simultaneously transmit

44
00:07:14,683 --> 00:07:17,083
across so many frequencies
like this.

45
00:07:17,083 --> 00:07:20,843
If it's genuine, it would rule out
any current technology we know of.

46
00:07:28,403 --> 00:07:32,843
<font color="
so we're putting together requests

47
00:07:32,843 --> 00:07:34,843
for telescope time with Parkes.

48
00:07:36,963 --> 00:07:40,843
We've also seen what looks like
complex modulation in the data...

49
00:07:48,083 --> 00:07:51,123
..and a powerful sustained
narrowband transmission

50
00:07:51,123 --> 00:07:52,923
at 1420 megahertz.

51
00:08:05,403 --> 00:08:09,403
<font color="
for now, but I imagine

52
00:08:09,403 --> 00:08:12,003
it's going to be pretty
common knowledge by tomorrow.

53
00:08:23,203 --> 00:08:27,083
All right. Suppose that you had an
old-fashioned analogue radio

54
00:08:27,083 --> 00:08:29,163
with a dial,

55
00:08:29,163 --> 00:08:33,123
and you turn that dial and you hear
<font color="

56
00:08:35,003 --> 00:08:39,443
And suddenly that noise goes away
and you hear a very clear tone.

57
00:08:41,443 --> 00:08:44,203
So that's the kind of thing
that we're looking for.

58
00:08:50,123 --> 00:08:53,563
So we're trying to think, you know,
where might we all think

59
00:08:53,563 --> 00:08:56,363
was a special sort of frequency
<font color="

60
00:08:58,563 --> 00:09:01,603
You look out in the universe,
what you see is lots

61
00:09:01,603 --> 00:09:03,723
and lots of hydrogen.

62
00:09:03,723 --> 00:09:07,323
And it just happens that there's
a natural process where you have

63
00:09:07,323 --> 00:09:09,163
lots and lots of hydrogen.

64
00:09:09,163 --> 00:09:11,483
It produces this radiation.

65
00:09:11,483 --> 00:09:15,563
<font color="
at this particular frequency,

66
00:09:15,563 --> 00:09:17,883
1420 megahertz.

67
00:09:21,323 --> 00:09:26,403
So one thought is that this is
a place that other civilisations

68
00:09:26,403 --> 00:09:30,643
would observe because they will also
be doing astronomy and they will

69
00:09:30,643 --> 00:09:33,043
also be looking at hydrogen
<font color="

70
00:09:33,043 --> 00:09:37,443
So 1420 megahertz, they will
have built receivers, but also

71
00:09:37,443 --> 00:09:40,403
probably built transmitters
at this frequency.

72
00:09:44,843 --> 00:09:48,203
So 1420 megahertz is a frequency we
know about, but it's also a

73
00:09:48,203 --> 00:09:50,283
frequency that the aliens
know about.

74
00:09:50,283 --> 00:09:53,403
<font color="
if they're really going to try

75
00:09:53,403 --> 00:09:55,923
"and get in touch with anybody,
maybe they would start out by

76
00:09:55,923 --> 00:09:57,883
"broadcasting at that frequency."

77
00:09:57,883 --> 00:09:59,803
CRACKLING

78
00:09:59,803 --> 00:10:04,043
You sort of rendezvous
at this frequency that every

79
00:10:04,043 --> 00:10:07,163
<font color="
will know.

80
00:10:10,443 --> 00:10:12,883
In all the time we've been
listening, we've only picked up

81
00:10:12,883 --> 00:10:15,563
a handful of signals
that look promising.

82
00:10:15,563 --> 00:10:19,443
Perhaps the best known of
these was back in the 1970s.

83
00:10:32,923 --> 00:10:35,963
<font color="
several groups of radio astronomers

84
00:10:35,963 --> 00:10:38,883
have from time to time taken part
in this attempt to tune in

85
00:10:38,883 --> 00:10:40,123
to the Galactic Club.

86
00:10:40,123 --> 00:10:43,723
And for a few of them, it's become
a full-time occupation.

87
00:11:00,563 --> 00:11:03,083
So 24 hours a day,
<font color="

88
00:11:03,083 --> 00:11:07,043
the observatory computers record
the sounds of the universe,

89
00:11:07,043 --> 00:11:09,883
and all they ever hear is a
hardly changing hiss.

90
00:11:12,003 --> 00:11:13,323
Except once.

91
00:11:25,523 --> 00:11:30,523
We were detecting signals
based on their strength.

92
00:11:32,523 --> 00:11:38,643
And we didn't have enough space
<font color="

93
00:11:38,643 --> 00:11:43,363
So the idea was we simply
printed out.

94
00:11:46,363 --> 00:11:47,483
Kerchunk!

95
00:11:47,483 --> 00:11:50,523
That was how the printer sounded
when it printed out

96
00:11:50,523 --> 00:11:54,643
all 120 characters at once.

97
00:12:05,963 --> 00:12:08,803
The whole system was working
without anybody

98
00:12:08,803 --> 00:12:10,843
<font color="

99
00:12:14,123 --> 00:12:15,523
SLIGHT RUMBLE

100
00:12:23,963 --> 00:12:27,283
There's always background noise.

101
00:12:27,283 --> 00:12:31,403
When this radio signal came through,

102
00:12:31,403 --> 00:12:37,243
starting out at six, that meant
six times the background noise.

103
00:12:37,243 --> 00:12:43,963
Now, the next letter E, the E
represented a signal strength

104
00:12:43,963 --> 00:12:46,483
<font color="

105
00:12:47,843 --> 00:12:51,963
Q is 26 times the background noise.

106
00:12:56,723 --> 00:13:01,563
At the peak, U was 30 times the
background noise.

107
00:13:01,563 --> 00:13:04,723
WHOOSHING, ELECTRONIC NOISES

108
00:13:09,323 --> 00:13:14,443
Then we dropped off J,
and then five.

109
00:13:14,443 --> 00:13:17,203
And then the signal was gone.

110
00:13:26,723 --> 00:13:28,683
<font color="

111
00:13:28,683 --> 00:13:31,363
we've got something
very interesting.

112
00:13:36,203 --> 00:13:39,243
I wrote the word "wow"

113
00:13:39,243 --> 00:13:42,483
in the margin of the printout.

114
00:13:43,963 --> 00:13:48,643
Wow, of course, indicates something
very interesting, and this turned

115
00:13:48,643 --> 00:13:55,603
out to be the strongest narrowband
<font color="

116
00:14:01,683 --> 00:14:05,523
So why was the wow signal
considered to be a good candidate

117
00:14:05,523 --> 00:14:07,003
for an ET signal?

118
00:14:07,003 --> 00:14:12,523
Because it moved across the sky
with the speed of the stars.

119
00:14:19,043 --> 00:14:23,603
And so that tells you that anything
that's, you know, a transmitter

120
00:14:23,603 --> 00:14:27,003
<font color="
across the sky at the same speed

121
00:14:27,003 --> 00:14:29,483
that the stars apparently
move across the sky.

122
00:14:29,483 --> 00:14:32,163
And this did all that,
so it looked good.

123
00:14:34,963 --> 00:14:39,963
The director of the observatory
wrote a letter after the detection.

124
00:14:39,963 --> 00:14:46,163
<font color="
suggestive of extraterrestrial

125
00:14:46,163 --> 00:14:51,963
"intelligent origin, but little
more can be said until it returns

126
00:14:51,963 --> 00:14:53,283
"for further study."

127
00:14:57,643 --> 00:14:59,803
It was not explained by something
on Earth.

128
00:14:59,803 --> 00:15:02,683
It is not explained by something
<font color="

129
00:15:02,683 --> 00:15:06,523
It was not explained by something
else that we know about in space.

130
00:15:06,523 --> 00:15:10,123
So, as far as we know, this was
an anomalous discovery.

131
00:15:10,123 --> 00:15:15,483
It matches many of the hallmarks
that scientists expect alien signals

132
00:15:15,483 --> 00:15:19,443
to have, and we still have no
<font color="

133
00:15:22,203 --> 00:15:27,163
I've talked to people at Ohio State
about this and asked them, what do

134
00:15:27,163 --> 00:15:30,723
they think it is? And they basically
sort of throw up their hands.

135
00:15:30,723 --> 00:15:32,683
Nobody knows. Nobody knows.

136
00:15:32,683 --> 00:15:36,363
And that's the problem
with finding something only once.

137
00:15:36,363 --> 00:15:39,603
<font color="
that you only see once.

138
00:15:44,003 --> 00:15:49,123
If the wow signal were to come
through now, it would be much

139
00:15:49,123 --> 00:15:51,923
different than what we saw.

140
00:15:51,923 --> 00:15:54,563
Technology has changed tremendously.

141
00:15:56,123 --> 00:15:59,963
Well, I'm hoping we actually
do discover signals

142
00:15:59,963 --> 00:16:03,083
<font color="
civilisations.

143
00:16:03,083 --> 00:16:06,403
I'm hoping I live long enough
to see that.

144
00:16:07,523 --> 00:16:13,043
I've only got a few years left
since I'm 82,

145
00:16:13,043 --> 00:16:19,763
and I would like to see something
during my remaining lifetime -

146
00:16:19,763 --> 00:16:21,683
however short that may be.

<font color="

148
00:16:49,243 --> 00:16:50,443
Random noise?

149
00:16:52,323 --> 00:16:53,483
Radio static?

150
00:16:55,763 --> 00:16:57,403
Maybe a muffled voice.

Are we alone in the universe?

154
00:18:27,283 --> 00:18:31,963
A new discovery revealed this week
has many thinking maybe we aren't.

157
00:18:35,603 --> 00:18:38,683
..from outer space? No, Francis,
mysterious radio signals

158
00:18:38,683 --> 00:18:42,043
haven't picked up strong radio
signals about...

159
00:18:42,043 --> 00:18:46,363
They saw one area that had a signal,

160
00:18:46,363 --> 00:18:48,003
but the signal...
<font color="

161
00:18:48,003 --> 00:18:51,163
So can we imagine that it's likely
that this signal we're picking up

162
00:18:51,163 --> 00:18:53,603
was sent by thinking beings?

163
00:18:55,443 --> 00:18:58,523
Just the idea of intelligence
elsewhere in the universe

Let's turn now to our science
editor, David Shukman.

168

David, these seem like intriguing
reports. What do we actually know?

Well, there's a lot of excitement
about this around the world.

170
00:19:36,403 --> 00:19:39,203
And with that, a great deal
<font color="

171
00:19:39,203 --> 00:19:41,683
Some of it, frankly, pretty
far-fetched,

172
00:19:41,683 --> 00:19:44,363
some sounding more plausible.

173
00:19:44,363 --> 00:19:48,283
What we're pretty certain about
is that the signal did indeed

174
00:19:48,283 --> 00:19:51,883
come from space, and that
it was really powerful.

175
00:19:51,883 --> 00:19:55,363
But beyond that, frankly,
<font color="

176
00:20:04,283 --> 00:20:05,643
During the course of the day,

177
00:20:05,643 --> 00:20:08,043
I've been talking to a lot
of different scientists,

178
00:20:08,043 --> 00:20:11,483
and a few of them are floating
the notion that the signal

179
00:20:11,483 --> 00:20:15,803
may contain some kind of data -
information, but in a form

180
00:20:15,803 --> 00:20:17,883
<font color="

181
00:20:20,803 --> 00:20:24,563
And if that's the case -
and it's a massive if - obviously

182
00:20:24,563 --> 00:20:28,843
it may take years before we get to
grips with what this is all about.

183
00:20:49,083 --> 00:20:54,123
The question about deciphering
messages is always so complicated

184
00:20:54,123 --> 00:20:56,803
<font color="
looking for.

185
00:20:56,803 --> 00:20:58,323
WHALES CALL

186
00:21:01,683 --> 00:21:03,923
Whales are a really good
study object.

187
00:21:03,923 --> 00:21:07,683
They are in some ways the closest
thing that we have to aliens

188
00:21:07,683 --> 00:21:09,283
here on Earth.

189
00:21:13,203 --> 00:21:15,923
Whales are highly intelligent

190
00:21:15,923 --> 00:21:20,483
<font color="
different from ours.

191
00:21:22,163 --> 00:21:25,443
The patterns that we hear
are clearly patterns

192
00:21:25,443 --> 00:21:27,083
that we recognise as music.

193
00:21:27,083 --> 00:21:28,523
They're repeated patterns.

194
00:21:28,523 --> 00:21:30,563
They are pitched.

195
00:21:30,563 --> 00:21:34,723
It is a form of vocalising

196
00:21:34,723 --> 00:21:38,163
that we would think of as
<font color="

197
00:21:38,163 --> 00:21:41,723
But even at that level, we don't
really know what it's for.

198
00:21:44,003 --> 00:21:47,203
Is it music? Is it language?
What does it mean?

199
00:21:47,203 --> 00:21:49,243
How is it used? Who responds?

200
00:21:52,403 --> 00:21:56,683
I think at the best of times,
it can give us a sense of

201
00:21:56,683 --> 00:21:59,563
<font color="

202
00:21:59,563 --> 00:22:03,763
And how many layers we have to cut
through in order to get somewhere.

203
00:22:07,803 --> 00:22:15,123
When I look at how Hollywood
portrays science fiction, connecting

204
00:22:15,123 --> 00:22:19,843
to contacts and so on, one of the
things that I think is unreal

205
00:22:19,843 --> 00:22:24,283
<font color="
to people like ourselves.

206
00:22:24,283 --> 00:22:28,203
People that can readily communicate,
have similar ambitions,

207
00:22:28,203 --> 00:22:29,523
similar responses.

208
00:22:32,723 --> 00:22:37,083
But when I think about intelligent
life and the variety of it,

209
00:22:37,083 --> 00:22:41,123
when I think the fact that,
<font color="

210
00:22:41,123 --> 00:22:43,083
we've got dogs, we've got apes.

211
00:22:45,603 --> 00:22:48,643
We've got octopi
that have their intelligence

212
00:22:48,643 --> 00:22:50,643
in their arms, not in their head.

213
00:22:53,083 --> 00:22:55,443
We can't talk to most
of the creatures on Earth

214
00:22:55,443 --> 00:22:57,123
in an intelligent way.

215
00:22:57,123 --> 00:23:00,563
<font color="
to the intelligent civilisations?

216
00:23:02,283 --> 00:23:05,603
I'm not sure we'll ever
understand them.

217
00:23:05,603 --> 00:23:07,603
That is a big challenge.

218
00:23:10,603 --> 00:23:15,683
You know, one of the things that we
often forget is that a sense

219
00:23:15,683 --> 00:23:20,643
of timescale might be incredibly
<font color="

220
00:23:20,643 --> 00:23:25,443
for a technological civilisation
that evolved somewhere else.

221
00:23:27,163 --> 00:23:34,123
They might think in a much faster
time or a much slower time,

222
00:23:34,123 --> 00:23:38,043
and the rate at which things change

223
00:23:38,043 --> 00:23:42,123
and present information, as humans,

224
00:23:42,123 --> 00:23:45,483
we just might not be able
<font color="

225
00:23:52,923 --> 00:23:55,603
It's not, you know,
"Here's a movie!" Right?

226
00:23:55,603 --> 00:23:57,883
It's not going to be that way.
It's not going to be,

227
00:23:57,883 --> 00:23:59,283
"Here's a movie of the aliens!"

228
00:23:59,283 --> 00:24:01,323
"Oh, you want to Facetime
with the alien?" Right?

229
00:24:01,323 --> 00:24:03,003
<font color="

230
00:24:03,003 --> 00:24:05,203
So it's going to be a mixture
of responses.

231
00:24:05,203 --> 00:24:09,643
But for those who are, you know,
on team science, it's going to

232
00:24:09,643 --> 00:24:13,563
be incredibly exciting because
now we have new stuff

233
00:24:13,563 --> 00:24:17,243
to study that is unlike anything
<font color="

234
00:24:51,243 --> 00:24:54,443
Hello to everyone new
who's joining us today.

235
00:24:54,443 --> 00:24:58,163
So our teams have been running
multiple scenarios over the past few

236
00:24:58,163 --> 00:25:01,963
days, and it's looking increasingly
unlikely that the signal

237
00:25:01,963 --> 00:25:05,043
would have originated
<font color="

238
00:25:10,083 --> 00:25:13,843
Our best guess is that we picked up
a reflection from another source,

239
00:25:13,843 --> 00:25:17,323
or maybe something that actually
crossed Voyager's line of sight.

240
00:25:26,123 --> 00:25:29,523
We just started to model different
potential transmitting bodies.

241
00:25:31,443 --> 00:25:34,123
<font color="
any conclusions.

242
00:25:43,963 --> 00:25:46,843
I'd say there's decades
of work to be done here.

243
00:26:02,163 --> 00:26:04,203
What's the point? I mean, what if
the aliens

244
00:26:04,203 --> 00:26:05,803
are living here on Earth already?

245
00:26:05,803 --> 00:26:08,723
Here's my theory.
First of all, I love how they say

246
00:26:08,723 --> 00:26:12,403
<font color="
secret government operation.

247
00:26:12,403 --> 00:26:14,563
Well, it's secret.
They're not going to tell us!

248
00:26:14,563 --> 00:26:18,083
Even Nasa people, ex-Nasa
people that come out and say,

249
00:26:18,083 --> 00:26:20,523
"Look, mate, aliens..." They retire
and they're like,

250
00:26:20,523 --> 00:26:21,803
<font color="

251
00:26:21,803 --> 00:26:24,643
"Like, they just are. Like, we're
fully aware of them." But they don't

252
00:26:24,643 --> 00:26:27,003
tell people because it would cause
too much of an uproar.

253
00:26:27,003 --> 00:26:30,323
Anyone that says that in the
entire a...

254
00:26:30,323 --> 00:26:32,363
It's been days now,

255
00:26:32,363 --> 00:26:36,563
<font color="
is still puzzling scientists

256
00:26:36,563 --> 00:26:40,163
around the world. Where it came
from and what it might mean

257
00:26:40,163 --> 00:26:42,563
are being studied intensely
right now.

258
00:26:45,043 --> 00:26:49,963
And in the absence of anything
concrete, all kinds of unfounded

259
00:26:49,963 --> 00:26:53,843
<font color="
unsettling - are being stirred up.

260
00:26:56,363 --> 00:26:59,323
Can everyone please chill out
about this alien signal?

261
00:26:59,323 --> 00:27:02,603
Freaking out that they're coming to
get us... Call the Avengers...

262
00:27:02,603 --> 00:27:05,163
I hate to break it to you guys,
but it's a hoax.

263
00:27:13,323 --> 00:27:16,763
<font color="

264
00:27:16,763 --> 00:27:18,923
This is one of those things
that some people

265
00:27:18,923 --> 00:27:20,843
like to decide for themselves.

266
00:27:20,843 --> 00:27:24,843
I feel like, you know, it's their
language we don't really understand

267
00:27:24,843 --> 00:27:26,723
but they're trying to make contact.

268
00:27:26,723 --> 00:27:28,923
And they are coming for us.

269
00:27:28,923 --> 00:27:31,083
<font color="

270
00:27:31,083 --> 00:27:34,403
Make sure you have enough supplies
and get ready for Armageddon,

271
00:27:34,403 --> 00:27:37,243
because this is going to be all out

272
00:27:37,243 --> 00:27:41,523
intergalactic war.
Full-scale alien apocalypse.

273
00:27:43,963 --> 00:27:48,243
With such an unclear signal,
without a very obvious intent

274
00:27:48,243 --> 00:27:51,883
<font color="
would be a lot of uncertainty.

275
00:27:51,883 --> 00:27:54,163
And uncertainty breeds anxiety.

276
00:28:03,883 --> 00:28:08,283
We do see disturbance in people's
day-to-day routines when big events

277
00:28:08,283 --> 00:28:10,803
happen. We saw this certainly with
the global pandemic,

278
00:28:10,803 --> 00:28:13,763
that people rushed out because
<font color="

279
00:28:13,763 --> 00:28:16,963
that there would be circumstances
in which supplies would be limited.

280
00:28:18,523 --> 00:28:21,043
I think you'll see an increase
in people feeling that there

281
00:28:21,043 --> 00:28:24,523
has to be something I can do,
so what can I do to prepare?

282
00:28:24,523 --> 00:28:28,123
And I will go out and I will buy
<font color="

283
00:28:28,123 --> 00:28:31,243
paper, I'll stock up on water
just in case.

284
00:28:31,243 --> 00:28:34,003
And that's a way of reassuring
yourself that you still have some

285
00:28:34,003 --> 00:28:35,643
control over the situation.

286
00:29:15,443 --> 00:29:17,643
I'm sure a lot of things
would be happening

287
00:29:17,643 --> 00:29:19,763
<font color="

288
00:29:21,163 --> 00:29:24,323
But I can assure you the scientific
community would be really focused

289
00:29:24,323 --> 00:29:27,403
on trying to understand
the nature of that signal

290
00:29:27,403 --> 00:29:31,043
and its characteristics,
and where it was coming from.

291
00:29:31,043 --> 00:29:34,283
Is it far away? Or, you know, maybe
<font color="

292
00:29:34,283 --> 00:29:36,203
or passing through the solar system.

293
00:29:36,203 --> 00:29:38,843
So, you know, we'd be working hard
and trying to understand

294
00:29:38,843 --> 00:29:40,443
those kinds of things.

295
00:29:57,843 --> 00:30:02,003
We've had a number of automatic
warnings over the last few hours.

296
00:30:04,243 --> 00:30:07,123
It's coming from multiple
<font color="

297
00:30:08,923 --> 00:30:12,403
Chile and the Canaries both
flagged objects of interest.

298
00:30:15,003 --> 00:30:17,483
We'll keep you updated on the
situation.

299
00:31:47,163 --> 00:31:52,963
With the Spaceguard Survey,
Congress mandated that we study the

300
00:31:52,963 --> 00:32:00,283
sky and find at least 90% of all
<font color="

301
00:32:00,283 --> 00:32:05,483
So because of this, a number
of surveys have started.

302
00:32:05,483 --> 00:32:09,963
Right now, there's about seven
looking at the entire sky

303
00:32:09,963 --> 00:32:13,483
every night in an automated format
to search for moving objects.

304
00:32:17,723 --> 00:32:20,483
Without these surveys, I think
<font color="

305
00:32:20,483 --> 00:32:23,963
have never made the discovery
that we made back in 2017.

306
00:32:38,643 --> 00:32:40,483
We've never seen anything
like this before.

307
00:32:40,483 --> 00:32:41,923
We've never seen anything like it.

308
00:32:41,923 --> 00:32:44,363
And we don't really have any idea
of how you'd make it.

309
00:32:44,363 --> 00:32:47,043
<font color="
scratching their heads

310
00:32:47,043 --> 00:32:48,723
and coming up with ideas.

311
00:32:48,723 --> 00:32:52,163
But at the moment, we've only got
a very small amount of data,

312
00:32:52,163 --> 00:32:54,923
so it's difficult to tell
what it is.

313
00:32:54,923 --> 00:32:56,643
Could it be aliens?

314
00:32:56,643 --> 00:32:58,723
It could be. Um...

315
00:32:58,723 --> 00:33:00,363
<font color="

316
00:33:14,763 --> 00:33:18,683
It was a visitor from elsewhere
in our galaxy.

317
00:33:20,603 --> 00:33:23,363
A relic from another
planetary system.

318
00:33:34,683 --> 00:33:39,203
My colleague called me at home
and said, "Karen, I think

319
00:33:39,203 --> 00:33:41,923
"we have found an
interstellar object."

320
00:33:41,923 --> 00:33:44,043
<font color="

321
00:33:44,043 --> 00:33:48,043
I was thinking, "Oh, shit!
This shouldn't be today.

322
00:33:48,043 --> 00:33:51,003
"I just want to relax!"
But then I got very excited.

323
00:33:58,923 --> 00:34:04,283
So we had about five or six days
in which to do all of the science.

324
00:34:08,603 --> 00:34:12,043
You're pulling in long days -
<font color="

325
00:34:12,043 --> 00:34:15,443
Everybody was. And I was
coordinating everyone,

326
00:34:15,443 --> 00:34:19,163
bringing in the data,
analysing the data.

327
00:34:19,163 --> 00:34:22,443
And what this meant was
I lived in my office.

328
00:34:25,523 --> 00:34:28,923
Air mattress, sleeping bag -
it's quite cosy.

329
00:34:28,923 --> 00:34:32,443
<font color="
of sleep and get back to the data.

330
00:34:37,683 --> 00:34:41,203
But the first really big
surprise, I think, was

331
00:34:41,203 --> 00:34:44,163
how much it changed in brightness.

332
00:34:49,803 --> 00:34:55,163
If you have reflected light coming
from the big side of an object,

333
00:34:55,163 --> 00:34:56,723
it will be bright.

334
00:34:56,723 --> 00:35:01,083
<font color="
a small amount of reflected light.

335
00:35:01,083 --> 00:35:05,123
So you can use this brightness
measurement as a measurement

336
00:35:05,123 --> 00:35:08,163
of effectively how elongated
something is.

337
00:35:13,843 --> 00:35:17,963
I think it is a really unusual
object.

338
00:35:17,963 --> 00:35:21,483
<font color="

339
00:35:21,483 --> 00:35:24,523
You know, it's sort of ten times
longer than it is broad.

340
00:35:26,523 --> 00:35:30,243
I don't really know what you call
the thing because it didn't

341
00:35:30,243 --> 00:35:33,843
really have the normal properties
you would expect from a comet.

342
00:35:37,763 --> 00:35:39,443
We were rather shocked.

343
00:35:39,443 --> 00:35:43,163
<font color="
that is that elongated.

344
00:35:43,163 --> 00:35:46,403
Typically, if you have elongated
things, eventually they'll hit

345
00:35:46,403 --> 00:35:49,043
something and break.
So it's just very unusual

346
00:35:49,043 --> 00:35:50,963
to have something that long.

347
00:35:53,603 --> 00:35:57,443
We contacted two people
<font color="

348
00:35:57,443 --> 00:35:59,243
language, and we said,

349
00:35:59,243 --> 00:36:03,603
"You have two days to devise a
Hawaiian name for us."

350
00:36:03,603 --> 00:36:06,923
And so they did. By Sunday, they
came up with a name

351
00:36:06,923 --> 00:36:11,203
and they suggested Oumuamua,
which means scout or messenger

352
00:36:11,203 --> 00:36:14,003
<font color="
reaching out to us.

353
00:36:20,843 --> 00:36:23,723
It came in going very fast,
and there were two things

354
00:36:23,723 --> 00:36:26,403
that were different about it
that made it quite puzzling.

355
00:36:26,403 --> 00:36:32,963
One was its shape, and it also moved
in such a way that it appeared

356
00:36:32,963 --> 00:36:35,963
<font color="
on it other than gravity.

357
00:36:35,963 --> 00:36:37,963
Now, what might that have been?

358
00:36:37,963 --> 00:36:42,123
Comets do this all the time,
and the other force is the material

359
00:36:42,123 --> 00:36:43,683
being ejected from their surface.

360
00:36:43,683 --> 00:36:47,243
So was it cometary in nature?

361
00:36:47,243 --> 00:36:50,203
Well, there was no evidence
<font color="

362
00:36:51,923 --> 00:36:54,763
So what was happening
was a bit of a mystery.

363
00:37:02,283 --> 00:37:04,043
Not everybody thought it was,
you know,

364
00:37:04,043 --> 00:37:06,323
just a natural thing -
just an old rock.

365
00:37:06,323 --> 00:37:09,043
Some people thought maybe it was
part of an alien craft.

366
00:37:11,043 --> 00:37:14,363
<font color="
that it didn't sort of,

367
00:37:14,363 --> 00:37:16,323
you know, move smoothly.

368
00:37:16,323 --> 00:37:18,643
It seemed to be slightly
accelerating.

369
00:37:18,643 --> 00:37:20,563
It was picking up speed.

370
00:37:20,563 --> 00:37:24,643
It was moving like it had some
sort of engine

371
00:37:24,643 --> 00:37:26,243
connected to it or something.

372
00:37:30,563 --> 00:37:34,123
<font color="
really was.

373
00:37:38,043 --> 00:37:41,923
Observatories around the world
discovered that the object

374
00:37:41,923 --> 00:37:43,323
was a lowly voyager.

375
00:37:43,323 --> 00:37:47,723
Was 'Oumuamua an alien artefact?

376
00:37:47,723 --> 00:37:50,523
Observatories all around and above
the world

377
00:37:50,523 --> 00:37:53,443
<font color="
half-mile long object

378
00:37:53,443 --> 00:37:56,203
to learn as much as possible
about this cosmic visitor

379
00:37:56,203 --> 00:37:58,323
before it moved too far away to see.

380
00:38:01,003 --> 00:38:03,363
The Breakthrough Project
decided to take

381
00:38:03,363 --> 00:38:06,523
one of the big radio telescopes -
<font color="

382
00:38:06,523 --> 00:38:10,563
and listen in case there were
signals coming from 'Oumuamua.

383
00:38:10,563 --> 00:38:14,163
And several of the press asked me,
"Isn't this a silly experiment?"

384
00:38:14,163 --> 00:38:15,363
And I said, "No.

385
00:38:15,363 --> 00:38:17,523
"You know, what if it's alien
technology?

386
00:38:17,523 --> 00:38:19,483
<font color="
the experiment?

387
00:38:19,483 --> 00:38:20,763
"This is your one chance.

388
00:38:20,763 --> 00:38:23,043
"It's a simple, easy experiment."

389
00:38:23,043 --> 00:38:26,643
But nothing was detected from any
of the radio experiments.

390
00:40:30,763 --> 00:40:34,723
The idea of aliens, here,
is so scary.

391
00:40:38,243 --> 00:40:41,043
<font color="
many questions.

392
00:40:41,043 --> 00:40:43,483
How they think, how they see us.

393
00:40:48,043 --> 00:40:50,363
This thing was terrifying.

394
00:40:50,363 --> 00:40:52,043
I trust no alien.

395
00:40:52,043 --> 00:40:54,883
You know, I think is it time for me
to move to another planet yet?

396
00:40:54,883 --> 00:40:58,443
What else is this alien race

NEWSREADER: The consensus
among scientists

398
00:41:23,803 --> 00:41:27,883
is that although the object is
moving extremely rapidly,

399
00:41:27,883 --> 00:41:32,523
it does not pose any danger to us
here on Earth.

400
00:41:32,523 --> 00:41:35,443
And while this could prove to be one
<font color="

scientific discoveries of all time,

402
00:41:37,763 --> 00:41:41,643
it's triggered a frenzy
of diplomatic activity.

403
00:41:41,643 --> 00:41:44,043
There have been discussions
around the clock

404
00:41:44,043 --> 00:41:48,523
at the UN, and there's due to be
an emergency special session.

405
00:41:48,523 --> 00:41:52,043
<font color="
as the world's governments

406
00:41:52,043 --> 00:41:56,683

00:42:13,443 --> 00:42:15,403
China is...

00:42:24,723 --> 00:42:31,163
Nations sharing all data connected
to Interstellar Artefact 1F2SJ U1.

413
00:42:56,363 --> 00:43:01,003
The discussion on air and space
at the United Nations

414
00:43:01,003 --> 00:43:08,763
<font color="
by the Russians in 1957.

415
00:43:08,763 --> 00:43:10,363
And there was a fear that,

416
00:43:10,363 --> 00:43:12,763
between Russia and
the United States,

417
00:43:12,763 --> 00:43:16,203
there would be an arms race
in outer space.

418
00:43:21,243 --> 00:43:25,723
At the 188th meeting

419
00:43:25,723 --> 00:43:31,043
of the Committee on Peaceful Uses
<font color="

420
00:43:31,043 --> 00:43:36,403
the question was asked that in view
of the tremendous impact

421
00:43:36,403 --> 00:43:41,563
any contact with an extraterrestrial
civilisation would have

422
00:43:41,563 --> 00:43:45,563
upon our planet, can this committee,
its asks,

423
00:43:45,563 --> 00:43:48,723
continue to ignore this possible
<font color="

424
00:43:50,363 --> 00:43:54,403
Most of the time, the Member States
do not want to discuss

425
00:43:54,403 --> 00:43:57,763
extraterrestrial intelligence
or life

426
00:43:57,763 --> 00:44:03,483
because it's assumed that this issue
will trivialise all the other issues

427
00:44:03,483 --> 00:44:05,603
that you're talking about.

428
00:44:05,603 --> 00:44:08,923
<font color="
weaponization in space -

429
00:44:08,923 --> 00:44:12,003
those are very important topics.

430
00:44:12,003 --> 00:44:17,323
But if there is extraterrestrial
intelligence, it will trivialise

431
00:44:17,323 --> 00:44:19,283
the other discussions.

432
00:44:22,763 --> 00:44:25,483
So if there was an interstellar
object,

433
00:44:25,483 --> 00:44:30,443
<font color="
radio signals,

434
00:44:30,443 --> 00:44:34,203
we invite the scientists
from all over the world

435
00:44:34,203 --> 00:44:36,763
to give its views to
the subcommittee

436
00:44:36,763 --> 00:44:38,203
on what we should do next.

437
00:44:38,203 --> 00:44:40,083
What does this mean, actually?

438
00:44:43,643 --> 00:44:49,043
It's very important the facts are
<font color="

439
00:44:49,043 --> 00:44:54,603
and that this body is able to take
the appropriate decisions...

440
00:44:54,603 --> 00:44:59,043
You cannot have a quick solution
in the United Nations.

441
00:44:59,043 --> 00:45:01,923
You can't. It has to be
extraordinary.

442
00:45:01,923 --> 00:45:04,043
And if it's to be
extraordinary,

443
00:45:04,043 --> 00:45:06,443
<font color="
extraordinary effort

444
00:45:06,443 --> 00:45:09,723
from the office of the
Secretary General

445
00:45:09,723 --> 00:45:13,083
to decide what to do next.

446
00:45:25,483 --> 00:45:27,363
It feels so surreal to be
saying this,

447
00:45:27,363 --> 00:45:31,723
but they're simply calling it
The Artefact -

448
00:45:31,723 --> 00:45:34,483
<font color="
technology

449
00:45:34,483 --> 00:45:37,083
formed somewhere other than Earth.

450
00:45:52,923 --> 00:45:56,163
What's amazing is how this whole
extraordinary saga began

451
00:45:56,163 --> 00:45:58,363
with just one signal.

452
00:45:58,363 --> 00:46:00,043
That's all we had to go on.

453
00:46:00,043 --> 00:46:04,683
It took another five or six days
<font color="

454
00:46:04,683 --> 00:46:07,523
And when it did, it was
really grainy.

455
00:46:07,523 --> 00:46:11,603
Now, just in the last few hours,
the first detailed pictures

456
00:46:11,603 --> 00:46:13,123
have started to appear,

457
00:46:13,123 --> 00:46:17,643
and they'll be vital for helping us
understand what this object is

458
00:46:17,643 --> 00:46:19,083
<font color="

459
00:46:25,603 --> 00:46:28,123
From what we've seen so far,

460
00:46:28,123 --> 00:46:31,683
the object appears to be tumbling
through space.

461
00:46:31,683 --> 00:46:35,603
There's no sign of it moving
under any kind of control,

462
00:46:35,603 --> 00:46:40,243
an extraordinary thought given that
it's almost 200 miles long

463
00:46:40,243 --> 00:46:43,083
<font color="
never seen before.

464
00:46:44,483 --> 00:46:47,523
These images raise so many
questions.

465
00:46:50,403 --> 00:46:53,243
Is this a structure in its
own right,

466
00:46:53,243 --> 00:46:56,683
or could it once have been part
of something larger?

467
00:46:59,723 --> 00:47:02,843
Is it genuinely artificial?

468
00:47:02,843 --> 00:47:05,083
<font color="

469
00:47:08,523 --> 00:47:12,523
And perhaps most important of all,
where did it come from?

470
00:47:30,283 --> 00:47:35,763
If I was on a desert island and a
broken bottle washed up on shore,

471
00:47:35,763 --> 00:47:38,043
that would be information that'd be
really exciting.

472
00:47:38,043 --> 00:47:42,243
It would mean I am not as deserted
<font color="

473
00:47:42,243 --> 00:47:43,963
and I think that's what this
would tell us.

474
00:47:43,963 --> 00:47:46,643
It wouldn't tell us everything we
wanted to know about the aliens,

475
00:47:46,643 --> 00:47:49,603
but it would tell us we're not as
alone as we thought we were.

476
00:47:51,603 --> 00:47:54,483
If there was some sort of alien
<font color="

477
00:47:54,483 --> 00:47:56,123
through the solar system,

478
00:47:56,123 --> 00:47:58,923
you would do as much to
characterise it.

479
00:47:58,923 --> 00:48:01,603
What is it made of? How big is it?
How dense is it?

480
00:48:01,603 --> 00:48:03,043
Is it spinning?

481
00:48:03,043 --> 00:48:06,603
These are the things that help
you understand what it is.

482
00:48:06,603 --> 00:48:09,563
<font color="
the data first,

483
00:48:09,563 --> 00:48:12,563
and then you interpret the data
afterwards.

484
00:48:12,563 --> 00:48:16,043
We'd be able to look at the light
that was being reflected off it

485
00:48:16,043 --> 00:48:17,883
and also being absorbed by it.

486
00:48:17,883 --> 00:48:20,163
And that might tell us about
<font color="

487
00:48:20,163 --> 00:48:21,443
of what we're looking at.

488
00:48:21,443 --> 00:48:23,803
We'd be able to tell if it's
a geological object,

489
00:48:23,803 --> 00:48:26,723
if it was made up of rock or if
it was made up of metal,

490
00:48:26,723 --> 00:48:29,523
and what kind of material it was.

491
00:48:29,523 --> 00:48:33,843
If it was artificial, we might be
<font color="

492
00:48:33,843 --> 00:48:36,563
chemical composition of the
artificial material is.

493
00:48:47,803 --> 00:48:49,563
This is absolutely real.

494
00:48:49,563 --> 00:48:52,643
It is something that they just
cannot explain.

495
00:48:52,643 --> 00:48:56,043
And it's something that they
are taking seriously.

496
00:48:56,043 --> 00:48:59,043
<font color="
which is often blamed

497
00:48:59,043 --> 00:49:02,163
for being the cause of UFOs,
is clueless.

498
00:49:02,163 --> 00:49:04,043
They have no idea what it is either.

499
00:49:04,043 --> 00:49:06,523
So the question mark is what is it?

500
00:49:08,723 --> 00:49:11,963
So you see this as a national
security issue?

501
00:49:11,963 --> 00:49:13,443
Absolutely.

502
00:49:13,443 --> 00:49:17,043
<font color="
that there is something there

503
00:49:17,043 --> 00:49:20,043
we need to be concerned about from
a national security standpoint.

504
00:49:20,043 --> 00:49:23,043
That we don't even understand
how you could build something

505
00:49:23,043 --> 00:49:27,043
that would do that. We don't even

506
00:49:27,043 --> 00:49:30,323
This is a whole difference
of kind, not degree.

In the language of the US Department
of Defense,

508
00:49:34,323 --> 00:49:37,043
unidentified aerial phenomena,

509
00:49:37,043 --> 00:49:40,643
which add fuel to the belief of some
that we are not alone.

<font color="

00:50:02,323 --> 00:50:05,123
America tonight is split
down the middle.

512
00:50:06,923 --> 00:50:10,883
Gun sales have more than doubled
across the country,

513
00:50:10,883 --> 00:50:13,403
with many convinced of
impending invasion.

514
00:50:16,163 --> 00:50:18,283
For many others, however,

515
00:50:18,283 --> 00:50:20,923
the events of the last few days
<font color="

516
00:50:20,923 --> 00:50:22,883
for intense celebration

517
00:50:22,883 --> 00:50:26,443
and represent one of the most
significant moments

518
00:50:26,443 --> 00:50:28,083
in human history.

519
00:50:36,963 --> 00:50:38,243
Oh, nice!

520
00:50:41,523 --> 00:50:44,363
Tonight, enthusiasts from all over
the state are out in force

521
00:50:44,363 --> 00:50:47,443
with their telescopes attempting
<font color="

522
00:50:49,603 --> 00:50:52,043
The race is on to identify
new features

523
00:50:52,043 --> 00:50:54,323
of this strange object.

524
00:50:54,323 --> 00:50:55,763
Wow!

525
00:50:55,763 --> 00:50:58,243
Amazing! It's...

526
00:50:58,243 --> 00:51:01,843
As you can see, it's a party
atmosphere,

527
00:51:01,843 --> 00:51:05,403
but everybody is just enjoying
the thrill.

528
00:51:05,403 --> 00:51:08,243
<font color="

529
00:51:44,283 --> 00:51:46,803
NEWSCASTER: Tonight, the first
studies into the Artefact

530
00:51:46,803 --> 00:51:48,043
are being released.

531
00:51:48,043 --> 00:51:51,443
One suggests it could be made of
a kind of metal,

532
00:51:51,443 --> 00:51:54,523
supporting the claim that it
is indeed artificial.

533
00:51:54,523 --> 00:51:57,923
<font color="
is working out

534
00:51:57,923 --> 00:51:59,283
where it's come from.

535
00:52:00,683 --> 00:52:04,163
And because Nasa and the
European Space Agency

536
00:52:04,163 --> 00:52:07,683
have developed ways of studying
distant stars,

537
00:52:07,683 --> 00:52:12,883
it is possible that we could peer
back along the object's path

538
00:52:12,883 --> 00:52:15,803
<font color="
habitable worlds.

539
00:52:24,043 --> 00:52:27,643
When I started studying science,
we didn't know about exoplanets.

540
00:52:27,643 --> 00:52:31,923
The idea that we can detect planets
around other star systems

541
00:52:31,923 --> 00:52:34,123
is something within just the last
20 or 30 years

542
00:52:34,123 --> 00:52:36,483
<font color="

543
00:52:36,483 --> 00:52:41,043
The fact that exoplanets
actually exist,

544
00:52:41,043 --> 00:52:44,043
their reality is incredibly recent.

545
00:52:44,043 --> 00:52:47,923
It's in the '90s that we found
the first such planet.

546
00:52:52,283 --> 00:52:56,403
BILL CLINTON: I did not have sexual
relations with that woman.

547
00:53:01,883 --> 00:53:05,443
<font color="
has taken the first pictures

548
00:53:05,443 --> 00:53:08,043
of a planet outside the
solar system.

549
00:53:08,043 --> 00:53:10,403
It was found near two
developing stars,

550
00:53:10,403 --> 00:53:13,203
450 lightyears from Earth.

551
00:53:13,203 --> 00:53:15,843
Astronomers believe it's the first
concrete evidence

552
00:53:15,843 --> 00:53:18,403
<font color="
in deep space.

553
00:53:29,043 --> 00:53:31,043
Up until the last couple of decades,

554
00:53:31,043 --> 00:53:34,043
we didn't know that exoplanets
even existed.

555
00:53:34,043 --> 00:53:35,363
We thought they might.

556
00:53:35,363 --> 00:53:36,723
We hoped they might.

557
00:53:36,723 --> 00:53:39,203
And looking at our own solar system,
we thought,

558
00:53:39,203 --> 00:53:40,763
<font color="

559
00:53:40,763 --> 00:53:46,043
But we didn't have the technology
to be able to identify them.

560
00:53:46,043 --> 00:53:48,363
And then Kepler came along,
and now we do.

561
00:54:01,723 --> 00:54:05,043
When I was thinking of Kepler
and building a mission,

562
00:54:05,043 --> 00:54:08,283
one of the things I recognised
<font color="

563
00:54:08,283 --> 00:54:10,403
had a strategic objective -

564
00:54:10,403 --> 00:54:14,403
determine the extent of life
in our universe.

565
00:54:14,403 --> 00:54:15,923
And how would you do that?

566
00:54:18,683 --> 00:54:20,843
Well, if you had planets,

567
00:54:20,843 --> 00:54:22,803
lots of planets in the
habitable zone,

568
00:54:22,803 --> 00:54:24,043
Earth-sized planets,

569
00:54:24,043 --> 00:54:26,563
<font color="
the galaxy.

570
00:54:29,163 --> 00:54:30,923
When I speak of the
habitable zone,

571
00:54:30,923 --> 00:54:32,523
what we're talking about is,

572
00:54:32,523 --> 00:54:34,883
if we take a planet, we move it
close to the star,

573
00:54:34,883 --> 00:54:36,043
it's too hot.

574
00:54:36,043 --> 00:54:38,643
If you had water on a planet,
<font color="

575
00:54:38,643 --> 00:54:41,483
It would evaporate. It would be lost
to space. It's too hot.

576
00:54:41,483 --> 00:54:44,763
If you go very far from the star,
it's too cold.

577
00:54:44,763 --> 00:54:47,203
Any water there is frozen forever.

578
00:54:47,203 --> 00:54:51,363
So the intermediate region,
the Goldilocks zone,

579
00:54:51,363 --> 00:54:53,523
<font color="
on the surface,

580
00:54:53,523 --> 00:54:57,443
where we think it would be conducive
to the evolution of life.

581
00:54:57,443 --> 00:55:00,843
That's what we call
the habitable zone.

582
00:55:00,843 --> 00:55:03,043
Kepler was designed to find out -

583
00:55:03,043 --> 00:55:06,843
are Earth-like planets frequent
in our galaxy?

584
00:55:06,843 --> 00:55:08,643
<font color="

585
00:55:13,043 --> 00:55:17,163
T-minus ten, nine, eight, seven,

586
00:55:17,163 --> 00:55:22,043
six, five, four, three, two.

587
00:55:22,043 --> 00:55:24,043
Engine start. One, zero.

588
00:55:24,043 --> 00:55:27,483
And liftoff of the Delta II rocket
with Kepler

589
00:55:27,483 --> 00:55:31,603
on a search for planets in some way
like our own.

590
00:55:31,603 --> 00:55:33,043
<font color="

591
00:55:33,043 --> 00:55:35,723
Ground-lit solid motors are building
and chamber pressure.

592
00:55:37,963 --> 00:55:40,043
Can you see separation?

593
00:55:40,043 --> 00:55:42,523
And we have ignition of the
air-lit solid motors.

594
00:55:49,963 --> 00:55:52,043
When a telescope was launched,

595
00:55:52,043 --> 00:55:53,843
the thing was tumbling in space,

596
00:55:53,843 --> 00:55:56,043
<font color="
and that way.

597
00:55:56,043 --> 00:55:57,763
It couldn't operate properly.

598
00:55:59,723 --> 00:56:02,243
It's a real cliff-hanger.

599
00:56:10,323 --> 00:56:14,563
We were really worried that mission
might not work

600
00:56:14,563 --> 00:56:16,683
if we couldn't get it
to stop spinning.

601
00:56:23,843 --> 00:56:26,523
When they found the electronic
<font color="

602
00:56:26,523 --> 00:56:28,363
it shifted to a different system.

603
00:56:28,363 --> 00:56:32,043
It was able to stop the spinning
and point the antenna

604
00:56:32,043 --> 00:56:33,363
toward the Earth.

605
00:56:39,883 --> 00:56:43,563
Throw off the cover and what you
see is this magnificent image.

606
00:56:51,803 --> 00:56:57,043
82 detectors showing hundreds of
<font color="

607
00:56:57,043 --> 00:56:58,843
Every detector working.

608
00:57:08,603 --> 00:57:11,763
It meant that the mission
was certain to succeed.

609
00:57:11,763 --> 00:57:14,323
We would find thousands of planets.

610
00:57:14,323 --> 00:57:17,563
It was a beautiful,
magnificent image.

611
00:57:17,563 --> 00:57:19,083
I'll never forget it.

612
00:57:41,043 --> 00:57:45,723
<font color="
continuously stares at the stars,

613
00:57:45,723 --> 00:57:49,403
you can see planets moving
around these stars.

614
00:57:52,043 --> 00:57:56,363
You can see that the light dips
slightly in its brightness,

615
00:57:56,363 --> 00:57:58,763
and we can measure that dip.

616
00:57:58,763 --> 00:58:02,563
So we can tell, potentially,
<font color="

617
00:58:02,563 --> 00:58:04,163
what size the planet is.

618
00:58:04,163 --> 00:58:07,243
We can also look at the orbit
of the planet,

619
00:58:07,243 --> 00:58:09,043
how long it takes to go around
its star,

620
00:58:09,043 --> 00:58:11,323
and maybe how close it is
to its star.

621
00:58:11,323 --> 00:58:14,043
When we combine those with the
<font color="

622
00:58:14,043 --> 00:58:16,043
we can start to estimate
the temperature

623
00:58:16,043 --> 00:58:17,283
of the planet itself.

624
00:58:17,283 --> 00:58:19,883
And once we know that, we can
actually estimate

625
00:58:19,883 --> 00:58:22,603
its habitability potential and
whether it's somewhere

626
00:58:22,603 --> 00:58:25,363
that could be capable of supporting
<font color="

627
00:58:33,043 --> 00:58:36,963
I think the Kepler telescope has
been tremendously exciting

628
00:58:36,963 --> 00:58:42,243
because of the number and variety
of exoplanetary systems

629
00:58:42,243 --> 00:58:44,363
that have been discovered.

630
00:58:44,363 --> 00:58:48,643
With Kepler, it's - at least
in my opinion -

631
00:58:48,643 --> 00:58:52,523
<font color="
a potential

632
00:58:52,523 --> 00:58:54,923
for a lot of habitable worlds.

633
00:58:57,283 --> 00:59:01,083
The probability that we have life
in the universe goes up.

634
00:59:08,843 --> 00:59:11,043
We know for a fact -

635
00:59:11,043 --> 00:59:14,403
not speculation, for a fact -

636
00:59:14,403 --> 00:59:19,283
our galaxy is full of Earth-sized
<font color="

637
00:59:19,283 --> 00:59:22,923
It might very well be full of life.

638

NEWSREADER: Despite assurances
from Nasa

639
00:59:39,123 --> 00:59:42,403
that there are no other artificial
objects in the solar system,

640
00:59:42,403 --> 00:59:45,883
the last 24 hours have seen
air forces around the world

<font color="

642
00:59:54,643 --> 00:59:57,043
Meanwhile, troops have been
mobilised in parts

643
00:59:57,043 --> 01:00:01,403
of mainland Europe to help alleviate
some of the mounting food shortages

644
01:00:01,403 --> 01:00:03,083
and supply chain issues.

645
01:00:16,883 --> 01:00:20,643
Good morning, and thank you for
inviting us to present today.

646
01:00:20,643 --> 01:00:24,323
<font color="
what many of you have probably

647
01:00:24,323 --> 01:00:26,083
already heard from your contacts.

648
01:00:27,683 --> 01:00:32,043
We do not believe there are any more
of these objects approaching us,

649
01:00:32,043 --> 01:00:35,203
at least not within the timeframe
of weeks and months.

650
01:00:38,043 --> 01:00:40,683
So our main focus in the last
<font color="

651
01:00:40,683 --> 01:00:43,763
has been on narrowing down
a point of origin.

652
01:00:43,763 --> 01:00:46,603
We'd like to present today
what we consider to be

653
01:00:46,603 --> 01:00:48,723
the best candidate star systems.

654
01:00:55,123 --> 01:00:59,243
Using speed and trajectory data,
we were able to narrow down

655
01:00:59,243 --> 01:01:04,083
<font color="

656
01:01:07,683 --> 01:01:11,243
Then we discarded any systems
without an abundance

657
01:01:11,243 --> 01:01:13,603
of the elements seen in
the Artefact.

658
01:01:15,323 --> 01:01:17,803
Leaving us with these eight.

659
01:01:21,643 --> 01:01:24,923
Of these, only one we believe
might be old enough

660
01:01:24,923 --> 01:01:27,443
to be a potential home
<font color="

661
01:01:34,003 --> 01:01:36,363
21 Archers.

662
01:01:38,923 --> 01:01:43,083
A star system we believe is nearly
eight billion years old.

663
01:02:01,563 --> 01:02:03,243
Well, it's quite probable

664
01:02:03,243 --> 01:02:06,043
that something that we would find
will be older.

665
01:02:06,043 --> 01:02:10,763
You have to realise that, in our
region of the galaxy,

666
01:02:10,763 --> 01:02:14,363
<font color="
younger

667
01:02:14,363 --> 01:02:16,043
than the surrounding stars.

668
01:02:16,043 --> 01:02:20,283
So our neighbours are quite a bit
older than we are.

669
01:02:30,443 --> 01:02:32,403
Well, I think older stars
would be interesting

670
01:02:32,403 --> 01:02:34,883
just because they've been
around for a longer time.

671
01:02:34,883 --> 01:02:39,603
<font color="
period for life to evolve.

672
01:02:39,603 --> 01:02:43,363
And if it takes a long time for
intelligent life to evolve...

673
01:02:43,363 --> 01:02:46,043
We know it was something like
four billion years

674
01:02:46,043 --> 01:02:47,403
here on our planet.

675
01:02:47,403 --> 01:02:49,523
You know, if you give it another
<font color="

676
01:02:49,523 --> 01:02:52,603
so you have a star that's maybe
eight billion years old,

677
01:02:52,603 --> 01:02:56,163
then it's had twice the amount
of time to, you know,

678
01:02:56,163 --> 01:02:58,803
potentially produce an intelligent
civilisation.

679
01:02:58,803 --> 01:03:01,643
So old stars, I think,
are interesting.

680
01:03:06,043 --> 01:03:09,443
<font color="
for alien technology

681
01:03:09,443 --> 01:03:12,443
or alien life elsewhere
in the galaxy,

682
01:03:12,443 --> 01:03:15,363
we're almost certainly going to find
things that have been around

683
01:03:15,363 --> 01:03:16,723
a really long time.

684
01:03:16,723 --> 01:03:20,163
Really long time means millions
<font color="

685
01:03:20,163 --> 01:03:21,803
to billions of years old.

686
01:03:29,043 --> 01:03:31,643
If we found technology that was
a billion years old,

687
01:03:31,643 --> 01:03:35,483
that means, when Earth was covered
with microbes and slime,

688
01:03:35,483 --> 01:03:38,683
there's technology operating
on some other planet.

689
01:03:40,523 --> 01:03:43,083
<font color="
quite profound.

690
01:04:01,443 --> 01:04:03,083
Science Q.

691
01:06:41,323 --> 01:06:42,923
This is Anita Kay.

692
01:06:42,923 --> 01:06:46,043
Welcome back to The Insight.

693
01:06:46,043 --> 01:06:50,563
So what exactly is this thing
and what do we do now?

694
01:06:50,563 --> 01:06:55,723
Well, based on its erratic
and uncontrolled spin,

695
01:06:55,723 --> 01:06:59,563
<font color="
discovered some kind

696
01:06:59,563 --> 01:07:01,163
of technological debris.

697
01:07:03,923 --> 01:07:08,043
A piece of cosmic junk that
originated somewhere

698
01:07:08,043 --> 01:07:09,843
in the Sagittarius system.

699
01:07:12,123 --> 01:07:15,163
The question some are now starting
to ask is...

700
01:07:17,123 --> 01:07:19,403
..should we attempt to send
<font color="

701
01:07:20,963 --> 01:07:23,043
And if so,

702
01:07:23,043 --> 01:07:24,523
what should we say?

703
01:07:29,923 --> 01:07:35,083
Good evening, and welcome to
the 699th meeting

704
01:07:35,083 --> 01:07:36,803
of the Security Council...

705
01:07:38,403 --> 01:07:40,843
An unacceptable risk...

706
01:07:40,843 --> 01:07:44,683
So I think we'd need to gather
as much information together

707
01:07:44,683 --> 01:07:46,483
<font color="

708
01:07:47,963 --> 01:07:50,283
You know, we've got this thing
in our head.

709
01:07:50,283 --> 01:07:52,923
It's sort of limited, you know,

710
01:07:52,923 --> 01:07:56,043
by the physical scale of it.

711
01:07:56,043 --> 01:07:58,883
But, you know, there might be other
things out there

712
01:07:58,883 --> 01:08:03,603
that just has a capacity that
is completely beyond

713
01:08:03,603 --> 01:08:04,963
<font color="

714
01:08:06,163 --> 01:08:08,483
And so it's a bit like,
you know, ants.

715
01:08:08,483 --> 01:08:10,323
You know, trying to communicate
with ants.

716
01:08:10,323 --> 01:08:12,883
The gulf might be enormous
between ourselves

717
01:08:12,883 --> 01:08:15,883
and other intelligences.

718
01:08:15,883 --> 01:08:18,443
You'd have to think really hard
<font color="

719
01:08:18,443 --> 01:08:20,163
before you pressed the send button.

720
01:08:29,563 --> 01:08:35,603
It's been decided that space is the
common province of all humankind.

721
01:08:36,723 --> 01:08:40,763
And so, when you talk about
extraterrestrial life,

722
01:08:40,763 --> 01:08:43,643
then that obviously relates
to space,

723
01:08:43,643 --> 01:08:50,603
<font color="
world should decide on what to do.

724
01:08:52,323 --> 01:08:54,683
Well, it turns out that there
actually is a protocol

725
01:08:54,683 --> 01:08:56,243
for what you're supposed to do.

726
01:08:56,243 --> 01:08:58,603
And here it is, actually.

727
01:08:58,603 --> 01:09:01,043
"In the case of a confirmed
detection of a signal,

728
01:09:01,043 --> 01:09:04,523
<font color="
will not respond

729
01:09:04,523 --> 01:09:09,043
"without first seeking guidance and
consent of a broadly representative

730
01:09:09,043 --> 01:09:11,923
"international body, such as
the United Nations."

731
01:09:13,563 --> 01:09:16,003
Personally, I don't think
that there's any reason

732
01:09:16,003 --> 01:09:17,883
<font color="

733
01:09:17,883 --> 01:09:20,043
because we're broadcasting
all the time anyhow.

734
01:09:20,043 --> 01:09:24,723
All our radio, all our television,
all those signals,

735
01:09:24,723 --> 01:09:26,723
they just go right through
the ionosphere.

736
01:09:26,723 --> 01:09:28,963
Sure, they're not intended
for aliens.

737
01:09:30,363 --> 01:09:33,603
<font color="
off the Earth, out into space.

738
01:09:48,443 --> 01:09:52,043
Freeman Dyson is one of the people
that participated

739
01:09:52,043 --> 01:09:54,043
in the past years with us.

740
01:09:54,043 --> 01:09:58,643
And he says, if you ever announce
that you've detected a signal,

741
01:09:58,643 --> 01:10:01,603
everyone is going to transmit

742
01:10:01,603 --> 01:10:04,243
<font color="
they please.

743
01:10:04,243 --> 01:10:06,483
Right? And then he chuckles,
he says,

744
01:10:06,483 --> 01:10:10,923
"Hmm, and wouldn't that cacophony
be about the best

745
01:10:10,923 --> 01:10:14,243
"characterisation of 21st century
Earth?"

746
01:10:15,283 --> 01:10:16,523
Yo, what up, guys?

747
01:10:16,523 --> 01:10:18,603
<font color="
Challenge.

748
01:10:18,603 --> 01:10:21,283
I want to see what messages you've
got for those alien freaks.

749
01:10:21,283 --> 01:10:22,763
So don't forget...

750
01:10:22,763 --> 01:10:24,323
Kind of lonely.

751
01:10:24,323 --> 01:10:29,123
And I would be excited for there
to be some other civilisation

752
01:10:29,123 --> 01:10:31,723
out there that we might
<font color="

753
01:10:31,723 --> 01:10:34,883
If we didn't contact the aliens
then maybe we could learn from them

754
01:10:34,883 --> 01:10:37,563
and we would really lose out
on a good situation.

755
01:10:37,563 --> 01:10:40,163
So I think we should just
send a message,

756
01:10:40,163 --> 01:10:43,323
tell them that we're friends
and we won't hurt them.

757
01:10:43,323 --> 01:10:45,723
<font color="
me recently

758
01:10:45,723 --> 01:10:47,723
what my message would be to aliens.

759
01:10:47,723 --> 01:10:50,043
But some are also scary

760
01:10:50,043 --> 01:10:53,923
as it's civilised enough
to send a signal.

761
01:10:58,563 --> 01:11:01,643
You're listening to Talk Box
on Joy Radio.

762
01:11:01,643 --> 01:11:05,163
I'm Jen Wright, and we're going to
<font color="

763
01:11:05,163 --> 01:11:09,843
of the day, which is - what message
would you send to aliens?

764
01:11:09,843 --> 01:11:12,963
So, my message to aliens
would be

765
01:11:12,963 --> 01:11:16,203
those in power don't speak
for all of us.

766
01:11:16,203 --> 01:11:18,683
You've heard the sound
that they sent us, right?

767
01:11:18,683 --> 01:11:20,763
<font color="
Indecipherable...

768
01:11:20,763 --> 01:11:23,443
MUMBLED MESSAGES
AND INTERWEAVING VOICES

769
01:11:23,443 --> 01:11:26,443
..so I would send them equally
annoying stuff back.

770
01:11:26,443 --> 01:11:29,843
The hold music that
drives me mad.

771
01:12:06,723 --> 01:12:09,243
RADIO STATIC,
MUFFLED VOICES

<font color="
out into space forever.

773
01:12:17,403 --> 01:12:20,843
Well, if anyone's out there
and listening to this,

774
01:12:20,843 --> 01:12:23,483
hello from the people of Earth.

775
01:12:23,483 --> 01:12:26,443
It's nice to know we've got some
company at last.

776
01:12:28,443 --> 01:12:31,483
Anyway, here's one of our best,
<font color="

777
01:12:31,483 --> 01:12:34,043
MUSIC: Moonlight
by Claude Debussy

778
01:12:36,123 --> 01:12:38,283
Let us know what you think.

779
01:12:44,443 --> 01:12:48,683
Nasa is sending commands up to
the James Webb Space Telescope

780
01:12:48,683 --> 01:12:54,083
to align it perfectly with the
21 Sagittarius star system.

781
01:12:57,283 --> 01:13:00,443
It's a delicate operation
<font color="

782
01:13:00,443 --> 01:13:03,603
directing the telescope's
intricate mechanisms

783
01:13:03,603 --> 01:13:06,443
to get it into
just the right position.

784
01:13:07,643 --> 01:13:11,403
Now, once it's there, it'll deploy
what's called a coronagraph

785
01:13:11,403 --> 01:13:15,723
to gather just a few thousand
<font color="

786
01:13:15,723 --> 01:13:19,403
It's a little bit like the amount
of light you'd get from a candle

787
01:13:19,403 --> 01:13:22,043
four-and-a-half-thousand miles away.

788
01:13:25,043 --> 01:13:27,003
But by analysing that light,

789
01:13:27,003 --> 01:13:30,643
it should be possible to see
if there are planets there

790
01:13:30,643 --> 01:13:34,883
and to gather clues about what kind
<font color="

791
01:13:45,163 --> 01:13:48,643
If life is out there,
the James Webb Space Telescope

792
01:13:48,643 --> 01:13:52,603
is going to increase our probability
of finding it

793
01:13:52,603 --> 01:13:56,963
because it's way more sensitive
than previous telescopes.

794
01:13:56,963 --> 01:14:00,083
It's in space, which gives
<font color="

795
01:14:00,083 --> 01:14:02,523
unobstructed by our atmosphere.

796
01:14:02,523 --> 01:14:05,443
And it has the most modern
technologies.

797
01:14:09,323 --> 01:14:10,763
What I'm most interested in

798
01:14:10,763 --> 01:14:14,043
is the fact it's going to study
exoplanet atmospheres,

799
01:14:14,043 --> 01:14:16,763
and we're going to be looking
<font color="

800
01:14:18,763 --> 01:14:22,603
So a biosignature is effectively
a signature of biology.

801
01:14:22,603 --> 01:14:25,683
We use it as a sign of finding
something -

802
01:14:25,683 --> 01:14:27,443
it could be a molecule in a rock

803
01:14:27,443 --> 01:14:29,603
or it could be a gas
in an atmosphere,

804
01:14:29,603 --> 01:14:32,403
but something that can only be
<font color="

805
01:14:32,403 --> 01:14:35,283
It's only there because
there is life existing.

806
01:14:41,323 --> 01:14:44,323
You might look for water vapour,
oxygen and methane -

807
01:14:44,323 --> 01:14:46,083
that's a classic biosignature

808
01:14:46,083 --> 01:14:48,803
because on Earth those things derive
from life.

809
01:14:48,803 --> 01:14:51,363
So on an exoplanet, it would
<font color="

810
01:14:51,363 --> 01:14:53,003
the presence of life.

811
01:14:54,683 --> 01:14:59,643
A technosignature is any remotely
detectable evidence of technology.

812
01:15:02,243 --> 01:15:04,883
So CFCs are chlorofluorocarbons.

813
01:15:04,883 --> 01:15:08,683
They have a very long residence
time in the atmosphere.

814
01:15:09,923 --> 01:15:13,883
There are no sources of these kinds
<font color="

815
01:15:13,883 --> 01:15:15,683
other than our own industry.

816
01:15:20,003 --> 01:15:26,483
If you go all the way to thinking
about a technological civilisation

817
01:15:26,483 --> 01:15:32,923
that creates smog, CFCs,
then with a lot of hours

818
01:15:32,923 --> 01:15:37,363
you might in fact be able to detect
that smog

819
01:15:37,363 --> 01:15:41,203
<font color="
some sort of a technology

820
01:15:41,203 --> 01:15:43,003
on that planet.

821
01:16:22,083 --> 01:16:25,723
For 12 days, the world has held
its breath.

822
01:16:25,723 --> 01:16:29,923
Now, finally, we are beginning
to get some answers.

823
01:16:29,923 --> 01:16:34,403
The James Webb data has revealed
<font color="

824
01:16:44,523 --> 01:16:49,683
Well, there've been no radio signals
from it, no sign of activity,

825
01:16:49,683 --> 01:16:51,363
and no planets.

826
01:16:53,683 --> 01:16:57,963
But there are hints about what could
be the remains of a planet.

827
01:17:01,763 --> 01:17:06,083
But we do know that if planets get
too close to their stars,

828
01:17:06,083 --> 01:17:09,803
<font color="
gravitational forces.

829
01:17:09,803 --> 01:17:11,843
And if that happens...

830
01:17:11,843 --> 01:17:15,523
SPEECH DISTORTS: They get torn
apart by the gravitational forces.

831
01:17:15,523 --> 01:17:18,363
..what's left is a ring of dust
and debris.

832
01:17:18,363 --> 01:17:20,163
It's a very distinctive shape

833
01:17:20,163 --> 01:17:22,563
<font color="
to what we're seeing

834
01:17:22,563 --> 01:17:25,003
in the latest images released today.

835
01:17:26,483 --> 01:17:29,843
And it's similar to what we're
seeing in...

836
01:17:29,843 --> 01:17:31,643
SPEECH DISTORTS

837
01:17:40,163 --> 01:17:44,243
We're also getting clues
about what this ring is made of,

838
01:17:44,243 --> 01:17:47,163
and it seems to include
<font color="

839
01:17:47,163 --> 01:17:49,443
that are unlikely to be natural.

840
01:17:49,443 --> 01:17:52,163
Instead, they look somehow
manufactured.

841
01:17:55,083 --> 01:17:59,443
So there are suggestions
that this ring and the object

842
01:17:59,443 --> 01:18:03,363
that just passed through our
solar system may be relics

843
01:18:03,363 --> 01:18:05,683
of a past civilisation.

844
01:18:08,123 --> 01:18:12,203
<font color="
a search for life.

845
01:18:12,203 --> 01:18:16,483
It's more about delving into the
ancient history of deep space.

846
01:18:52,563 --> 01:18:55,203
Searching for life in our solar
system is one thing,

847
01:18:55,203 --> 01:18:59,003
but searching for life beyond,
it might be closer to archaeology,

848
01:18:59,003 --> 01:19:01,123
<font color="

849
01:19:01,123 --> 01:19:03,763
from what may now
be dead civilisations.

850
01:19:06,083 --> 01:19:09,363
Searching for extraterrestrial
relics is like archaeology.

851
01:19:10,363 --> 01:19:11,923
You know, I hope I'm wrong.

852
01:19:11,923 --> 01:19:14,723
I hope that the first sign
we have of life

853
01:19:14,723 --> 01:19:17,723
<font color="
doorstep and they're friendly.

854
01:19:17,723 --> 01:19:19,843
But I have to be realistic, too.

855
01:19:21,363 --> 01:19:24,763
I don't think that it's going to be,
"Hello!"

856
01:19:26,203 --> 01:19:27,523
"Hello."

857
01:19:28,523 --> 01:19:30,043
"How are you?"

858
01:19:30,043 --> 01:19:32,363
You know, a two-way communication.

859
01:19:35,843 --> 01:19:41,163
<font color="
to be a one-way communication

860
01:19:41,163 --> 01:19:45,483
such as we currently have with
Shakespeare or the ancient Greeks

861
01:19:45,483 --> 01:19:47,203
and the Romans.

862
01:19:49,683 --> 01:19:52,763
We can't ask questions of them,

863
01:19:52,763 --> 01:19:57,003
but they have provided us a wealth
of information

864
01:19:57,003 --> 01:19:59,123
<font color="

865
01:20:11,843 --> 01:20:15,803
I think if we detect evidence
of a single artefact

866
01:20:15,803 --> 01:20:17,323
or a single piece of evidence

867
01:20:17,323 --> 01:20:20,523
that there is another advanced
civilisation out there,

868
01:20:20,523 --> 01:20:23,123
well, then I think the floodgates
are open.

869
01:20:23,123 --> 01:20:24,923
<font color="

870
01:20:24,923 --> 01:20:28,883
Our main problem right now
is we are just one data point.

871
01:20:28,883 --> 01:20:31,163
We don't know if we're unique,

872
01:20:31,163 --> 01:20:35,043
but as soon as we have evidence
that it happened somewhere else

873
01:20:35,043 --> 01:20:38,003
and that life and intelligent life
evolved,

874
01:20:38,003 --> 01:20:40,523
<font color="

875
01:21:10,803 --> 01:21:12,043
Hello, good evening.

876
01:21:12,043 --> 01:21:15,603
Well, straight away let's focus on
that all-important cloud cover

877
01:21:15,603 --> 01:21:19,043
tending to break up
and translating into clear skies,

878
01:21:19,043 --> 01:21:22,643
which of course is great news if
there are any amateur astronomers

879
01:21:22,643 --> 01:21:27,003
<font color="
of this cosmic visitor.

880
01:21:29,603 --> 01:21:32,683
As we know, we're expecting
a few million people to mark

881
01:21:32,683 --> 01:21:35,523
the occasion throughout the country
over the course of this evening,

882
01:21:35,523 --> 01:21:37,443
and that's anywhere from
Snowdon Snowdon

883
01:21:37,443 --> 01:21:39,323
<font color="
to Trafalgar Square.

884
01:21:39,323 --> 01:21:41,403
Pretty mass gathering expected
there.

885
01:21:41,403 --> 01:21:43,723
But, a word of warning.

886
01:21:43,723 --> 01:21:47,323
Now, can you just see the telltale
signs of that cold front up north?

887
01:21:47,323 --> 01:21:50,803
Well, that's expected to sink
southwards at quite a pace.

888
01:21:50,803 --> 01:21:53,123
<font color="
light vigil,

889
01:21:53,123 --> 01:21:55,043
if you're going out tonight,

890
01:21:55,043 --> 01:21:57,923
bear this in mind and
please wrap up warmly.

891
01:22:29,163 --> 01:22:32,683
Our best guess is that we've
encountered an object

892
01:22:32,683 --> 01:22:34,763
created by an intelligence

893
01:22:34,763 --> 01:22:37,923
that existed
<font color="

894
01:22:40,203 --> 01:22:42,243
But our time with it is fleeting.

895
01:22:45,563 --> 01:22:48,723
Today, the artefact moves
out of sight

896
01:22:48,723 --> 01:22:51,963
as it makes its way
beyond the Solar System.

897
01:22:59,403 --> 01:23:01,203
It may be over a million years

898
01:23:01,203 --> 01:23:04,443
before it encounters another
star or planet.

899
01:23:15,363 --> 01:23:19,283
<font color="

900
01:23:19,283 --> 01:23:24,443
is that the miracle of complex life
is not unique to the Earth.

901
01:23:30,403 --> 01:23:34,283
But how long intelligent
civilisations last,

902
01:23:34,283 --> 01:23:37,843
and if they ever overlap,
remains unknown.

903
01:23:43,043 --> 01:23:48,803
As of right now, there's still every
<font color="

904
01:23:55,683 --> 01:23:59,203
And that means
we have a responsibility

905
01:23:59,203 --> 01:24:01,243
to protect what's happened here.

906
01:24:08,203 --> 01:24:11,523
The search for life
isn't over.

907
01:24:14,683 --> 01:24:16,683
It's really just beginning.

908
01:24:22,243 --> 01:24:27,163
Exploring space to determine
<font color="

909
01:24:27,163 --> 01:24:30,923
reminds me very much of what
the people in the Middle Ages did.

910
01:24:32,203 --> 01:24:36,283
They believed that one of the great
things they could do

911
01:24:36,283 --> 01:24:39,363
was build these beautiful cathedrals
to worship God.

912
01:24:40,883 --> 01:24:43,763
They knew when they started building
<font color="

913
01:24:43,763 --> 01:24:47,203
they would not live long enough to
see these cathedrals

914
01:24:47,203 --> 01:24:50,523
in their full glory,
to go inside and worship God.

915
01:24:50,523 --> 01:24:53,443
But their children or grandchildren
would do that.

916
01:24:53,443 --> 01:24:56,403
They had the faith to start,
to do the work.

917
01:24:59,203 --> 01:25:02,243
<font color="
we are doing those first steps.

918
01:25:02,243 --> 01:25:04,323
We are building that foundation.

919
01:25:06,883 --> 01:25:09,923
And it's not something that's
done in one lifetime.

920
01:25:11,603 --> 01:25:14,563
It's something that humankind does

921
01:25:14,563 --> 01:25:18,683
because it has faith that we need
and want to explore the universe...
