00:00:00.080 --> 00:00:00.560
By there.

2
00:00:00.640 --> 00:00:03.640
Welcome to another episode of Space Nats. I'm your host

3
00:00:03.680 --> 00:00:06.960
Andrew Dunkley. As always, it is great to have your company.

4
00:00:07.040 --> 00:00:09.039
Hope you're well, and I hope you can stay with

5
00:00:09.199 --> 00:00:12.640
us because we are going to give you yet another

6
00:00:12.919 --> 00:00:16.359
asteroid update. Yes, it's still in the news. I was

7
00:00:16.440 --> 00:00:20.160
reading stories online over the weekend and no, it's all

8
00:00:20.199 --> 00:00:23.559
doom and gloom twenty twenty four y r four. It's

9
00:00:23.600 --> 00:00:26.600
going to kill us all. Well, let's find out the truth.

10
00:00:26.920 --> 00:00:30.359
We're also going to answer a question. It's not the

11
00:00:31.280 --> 00:00:34.000
definitive answer, but it's the answer. At this point in time,

12
00:00:34.600 --> 00:00:39.000
are we alone? And the reason new data that's been

13
00:00:39.280 --> 00:00:42.159
released SpaceX has got itself into the news again for

14
00:00:42.200 --> 00:00:46.000
all the wrong reasons. And there might be another moon

15
00:00:46.359 --> 00:00:50.200
in our solar system that harbors a liquid ocean.

16
00:00:50.240 --> 00:00:53.399
We'll tell you which one it is. On this episode of.

17
00:00:53.520 --> 00:00:58.799
Space Nuts Channel ten nine.

18
00:00:59.039 --> 00:01:07.480
Ignition, Space Nuts three two one, Space.

19
00:01:07.319 --> 00:01:10.959
Nurse and I record it Nels good and he is

20
00:01:11.000 --> 00:01:14.640
back for more. It is Johnny Horner, professor of astrophysics

21
00:01:14.640 --> 00:01:16.560
at the University of Southern Queensland.

22
00:01:16.640 --> 00:01:19.040
Johnny, Hello, good afternoon, how are you going.

23
00:01:19.719 --> 00:01:23.959
I am well, good to see you and Johnny warned

24
00:01:24.000 --> 00:01:27.239
me that we might hear some dog interruption, not from

25
00:01:27.239 --> 00:01:30.560
the dog star but from the dog dogs. Yes, when

26
00:01:31.599 --> 00:01:34.400
the other half turns up, because they get very excited that.

27
00:01:34.400 --> 00:01:37.400
We've been really excited at people walking down the road.

28
00:01:37.519 --> 00:01:40.079
So well, yeah, that's maybe you can hear them. Maybe

29
00:01:40.120 --> 00:01:41.359
you come, but I'm hearing.

30
00:01:42.719 --> 00:01:46.079
The filters might be stopping it from getting through to

31
00:01:45.280 --> 00:01:50.200
the recording. Sometimes that happens. But yeah, well we've heard

32
00:01:51.280 --> 00:01:54.560
Jordie many many times on the podcast at at friend's house,

33
00:01:54.640 --> 00:01:58.799
so yes, not unusual, and we don't mind. We've been

34
00:01:58.799 --> 00:02:01.239
interrupted by all sorts of creatures on this show over

35
00:02:01.239 --> 00:02:06.599
the years. Let's start off with yet another update on

36
00:02:06.799 --> 00:02:09.800
our favorite asteroid might not be our favorite. If you

37
00:02:09.879 --> 00:02:12.879
read the Popular Prayers twenty twenty four four.

38
00:02:12.680 --> 00:02:16.560
What's the latest, Well, the latest, long and short is

39
00:02:16.599 --> 00:02:20.120
that catastrophe is averted. It is almost certainly not going

40
00:02:20.159 --> 00:02:23.560
to hit it. And this has come around a little

41
00:02:23.560 --> 00:02:25.680
bit quicker than I was expecting, actually, but I've seen

42
00:02:25.719 --> 00:02:30.120
some beautiful visualizations released by both European Space Agency and

43
00:02:30.199 --> 00:02:32.159
NASA over the last few days that have shown what's

44
00:02:32.199 --> 00:02:35.840
going on. So I mentioned on the previous episodes that

45
00:02:35.879 --> 00:02:38.400
we found this object back on the twenty seventh of December.

46
00:02:38.879 --> 00:02:41.080
They immediately found some old images that went back to

47
00:02:41.080 --> 00:02:43.120
the twenty fifth of December when it was closest to

48
00:02:43.159 --> 00:02:46.000
the Earth, and people have been observing it pretty full

49
00:02:46.000 --> 00:02:48.520
on ever since. Those that could do, because it's quite small,

50
00:02:48.599 --> 00:02:51.879
quite fent. As it receded from the Earth and end

51
00:02:51.960 --> 00:02:55.280
of January, the odds of it hitting the Earth got

52
00:02:55.360 --> 00:02:58.520
high enough in twenty thirty two, in eight years time,

53
00:02:58.960 --> 00:03:01.879
that it was flagged up as been potentially threatening and

54
00:03:01.919 --> 00:03:05.039
it got the second highest ever rating on the Plurmar scale.

55
00:03:05.479 --> 00:03:07.759
So basically, this thing is something to watch out for.

56
00:03:07.840 --> 00:03:09.240
We're not saying it's going to hit the Earth, but

57
00:03:09.280 --> 00:03:12.759
we need more data. As time's gone on since then,

58
00:03:12.800 --> 00:03:15.120
we've got more and more data, and for a while,

59
00:03:15.280 --> 00:03:18.360
the probability of hitting us on that day, on the

60
00:03:18.360 --> 00:03:22.520
twenty second of December twenty thirty two was increasing, and

61
00:03:22.560 --> 00:03:25.560
that was exactly what you'd expect. So you get more observations,

62
00:03:26.039 --> 00:03:28.199
which means our knowledge of where it will be on

63
00:03:28.240 --> 00:03:31.759
that fateful day gets better, so the area of uncertainty

64
00:03:31.759 --> 00:03:34.439
on where it will be get smaller, so you're shrinking

65
00:03:34.479 --> 00:03:37.360
the volume of space where the asteroid could be and

66
00:03:37.439 --> 00:03:40.879
if the Earth stays in that area, the Earth becomes

67
00:03:40.919 --> 00:03:43.439
a bigger fraction of that total area, so it's more

68
00:03:43.520 --> 00:03:44.159
likely to be hit.

69
00:03:44.759 --> 00:03:44.960
Yep.

70
00:03:45.159 --> 00:03:47.039
And what I said at the time was eventually we'd

71
00:03:47.039 --> 00:03:49.919
get enough observations that the Earth could potentially fall outside

72
00:03:49.919 --> 00:03:53.080
that area, so the area would shrink enough that the

73
00:03:53.080 --> 00:03:54.960
Earth kind of popped out of it, fell out onto

74
00:03:55.000 --> 00:03:57.560
the other side. And that's what's happened over the last

75
00:03:57.599 --> 00:04:01.599
few days. Now the Earth is not totally and absolutely

76
00:04:01.639 --> 00:04:04.199
out of the firing line, but it's almost as good

77
00:04:04.240 --> 00:04:06.000
as and I'm sure within a day or two it

78
00:04:06.039 --> 00:04:08.719
will drop to absolutely zero. So as of the time

79
00:04:08.759 --> 00:04:12.199
where recording this, which is February the twenty fifth, the

80
00:04:12.280 --> 00:04:15.960
latest probability of an impact is two point seven times

81
00:04:16.040 --> 00:04:19.240
ten to the minus five, which means no point not

82
00:04:20.319 --> 00:04:25.360
two seven percent, or one in thirty seven thousand. Now,

83
00:04:25.399 --> 00:04:27.680
given the last week we were talking about one in

84
00:04:27.759 --> 00:04:31.439
thirty three, that's a very dramatic change. And that's big. See,

85
00:04:31.920 --> 00:04:34.160
area that the object is going to be in has

86
00:04:34.160 --> 00:04:36.160
shrunk and shrunk and shrunk, and the Earth is essentially

87
00:04:36.199 --> 00:04:38.839
popped out of the outside. And that's what these beautiful

88
00:04:38.879 --> 00:04:42.839
visualizations that are popping up online are showing an interesting

89
00:04:42.879 --> 00:04:44.519
part of this so is that while Earth is out

90
00:04:44.519 --> 00:04:47.439
of the cross heads, the Moon is still in the crosshairs.

91
00:04:48.199 --> 00:04:50.480
So there remains a possibility that this thing could hit

92
00:04:50.519 --> 00:04:53.040
the Moon, but the probability of an impact on the

93
00:04:53.040 --> 00:04:55.399
Moon is still pretty low. So it isn't a case

94
00:04:55.480 --> 00:04:58.639
of we're saying the Earth is spared. Watch out anybody

95
00:04:58.680 --> 00:05:01.759
who's part of Project Tartemis, you know, walking around on

96
00:05:01.800 --> 00:05:04.759
the Moon in eight years time, if that happens. Rather,

97
00:05:04.879 --> 00:05:07.360
it's just that the Moon still hasn't fallen out of

98
00:05:07.360 --> 00:05:09.959
that area yet, but bad anticipate it probably will do.

99
00:05:10.399 --> 00:05:12.480
So the most likely outcome is that this thing will

100
00:05:12.480 --> 00:05:15.160
come close, but it's not going to be that close.

101
00:05:16.319 --> 00:05:18.600
Okay, Now, what if it did hit the Moon, what

102
00:05:18.680 --> 00:05:21.319
would be the effect. Would it just make a mighty

103
00:05:21.360 --> 00:05:25.199
big crater? It'd make not even that mighty, not even

104
00:05:25.240 --> 00:05:25.680
that big.

105
00:05:26.199 --> 00:05:28.600
A good rule of thumb on the Earth is that

106
00:05:28.680 --> 00:05:31.079
if something solid makes it to the surface of the Earth,

107
00:05:31.120 --> 00:05:33.839
the creater that thing will create is going to be

108
00:05:34.120 --> 00:05:37.839
to first order, nineteen times bigger than the impact. Little

109
00:05:37.839 --> 00:05:40.600
bit of wiggle room in there obviously a different material

110
00:05:40.639 --> 00:05:42.639
for the impact would have an impact. A different speed

111
00:05:42.680 --> 00:05:45.480
would have an impact, But first order, it's about a

112
00:05:45.560 --> 00:05:49.000
rule of nineteen. I think that changes slightly from body

113
00:05:49.040 --> 00:05:52.560
to body, but not hugely, because it's still the physics

114
00:05:52.560 --> 00:05:55.680
of rock hitting rock or metal hitting rock. What that

115
00:05:55.800 --> 00:05:57.600
means is, if this thing is the size of the

116
00:05:57.600 --> 00:06:00.879
best estiments, which is about fifty five meters, then you're

117
00:06:00.879 --> 00:06:04.000
looking at about a one kilometer crater, which I mean

118
00:06:04.120 --> 00:06:06.160
is substantial. It's big enough for us to observe, but

119
00:06:06.199 --> 00:06:10.560
it's nowhere near the biggest anywhere out there. It's probably

120
00:06:10.560 --> 00:06:12.920
not big enough that a substantial amount of material will

121
00:06:12.920 --> 00:06:16.120
be ejected from the Moon to reach us. But people

122
00:06:16.160 --> 00:06:18.399
have tried to fearmonger that a little bit. I've seen

123
00:06:18.439 --> 00:06:20.680
a few posts from people online saying if it hits

124
00:06:20.680 --> 00:06:22.319
the Moon, the Earth will get hit by a load

125
00:06:22.360 --> 00:06:27.480
of debris. Realistically, not much debris would reach the Earth,

126
00:06:27.600 --> 00:06:29.199
so we might get a little bit burning up in

127
00:06:29.240 --> 00:06:32.439
the atmosphere, but we wouldn't even probably notice, because it

128
00:06:32.480 --> 00:06:35.680
seems fairly small. I've seen some studies arguing that you

129
00:06:35.720 --> 00:06:38.319
need an impact or at least a kilometer across to

130
00:06:38.399 --> 00:06:40.680
eject enough material from the Moon for us to rarely

131
00:06:40.720 --> 00:06:42.720
pick it up and notice it from the point of

132
00:06:42.800 --> 00:06:43.600
view of looking up.

133
00:06:44.279 --> 00:06:46.920
Okay, all right, well we've got how long to wait?

134
00:06:48.399 --> 00:06:52.240
Just other great years, so we can revisit this in

135
00:06:52.279 --> 00:06:54.560
the future when Fred is once again looking at Aurora

136
00:06:55.040 --> 00:06:56.639
in Scandinavia.

137
00:06:57.399 --> 00:06:58.439
Why not? All right?

138
00:06:59.000 --> 00:07:02.800
So the good news is the odds have plummeted, and

139
00:07:03.199 --> 00:07:05.399
despite what I read in I don't know how many

140
00:07:05.439 --> 00:07:09.480
news outlets on Sunday, the story is very very different today.

141
00:07:09.600 --> 00:07:12.600
Yeah, it's a very fast moving story. And if you

142
00:07:12.680 --> 00:07:15.240
can find these little animations online, they're worth looking at

143
00:07:15.319 --> 00:07:19.120
because it shows you a line that is basically all

144
00:07:19.120 --> 00:07:21.600
the possible places the astro coup, and it's that's the

145
00:07:21.639 --> 00:07:25.079
result of lots of simulations with slightly different initial conditions

146
00:07:25.519 --> 00:07:29.199
that all much within our uncertainty where the object is currently,

147
00:07:29.439 --> 00:07:31.319
and you get this long stretch outline. And then with

148
00:07:31.399 --> 00:07:34.399
every day of new observations, that line gets shorter and

149
00:07:34.439 --> 00:07:37.079
shorter and shorter, and now the Earth is right on

150
00:07:37.120 --> 00:07:39.399
the very end of it, barely touched by any of them.

151
00:07:39.639 --> 00:07:42.240
And I'm sure tomorrow the earthwallpers scott free.

152
00:07:42.680 --> 00:07:47.680
Okay, that's good news, very good news.

153
00:07:50.639 --> 00:07:51.839
Space nuts.

154
00:07:52.120 --> 00:07:55.199
Now to a question that we do get from time

155
00:07:55.240 --> 00:07:58.360
to time from our audience asking about whether or not

156
00:07:58.480 --> 00:08:01.839
we are alone in the universe. I suppose that is

157
00:08:01.920 --> 00:08:06.360
one of the big questions yet to be answered as

158
00:08:06.360 --> 00:08:11.680
far as the wider well humanity is concerned. That question

159
00:08:11.959 --> 00:08:17.600
has got new data attached to it, which is very

160
00:08:17.639 --> 00:08:21.199
interesting because of the way it's been collected. And the

161
00:08:21.240 --> 00:08:24.560
downside is the result at this point in time, at

162
00:08:24.560 --> 00:08:26.720
this point in time, But yes, are.

163
00:08:26.560 --> 00:08:31.000
We alone so far? I think that's the best answerment

164
00:08:31.560 --> 00:08:31.879
it is.

165
00:08:32.879 --> 00:08:34.639
So there are two different ways that we'll look to

166
00:08:34.679 --> 00:08:36.840
answer this question, and two different things we're looking for.

167
00:08:37.559 --> 00:08:40.519
One is just to look for any evidence of any

168
00:08:40.600 --> 00:08:43.440
kind of life, and we're doing that within the Solar system,

169
00:08:43.559 --> 00:08:46.279
and we're doing outside of the Solar system by looking

170
00:08:46.320 --> 00:08:49.279
for subtle indications that there could be life in various

171
00:08:49.320 --> 00:08:52.480
places and will probably amount to finding something that's out

172
00:08:52.480 --> 00:08:55.440
of equilibrium that shouldn't be there. A good example being

173
00:08:55.480 --> 00:08:58.240
the phosphene observations on Venus a few years ago that

174
00:08:58.720 --> 00:09:01.840
reads a lot of excitement but are probably not actually

175
00:09:01.840 --> 00:09:04.759
a life, but we don't know. It's finding something out

176
00:09:04.799 --> 00:09:07.720
of place and inferring that life is the best explanation

177
00:09:08.360 --> 00:09:10.679
that could exist for it, and that's where we're going

178
00:09:10.720 --> 00:09:12.120
to be doing a lot of work in the coming

179
00:09:12.120 --> 00:09:15.759
decade or two looking at planets around the starts. That

180
00:09:15.919 --> 00:09:19.960
is a search for any life, particularly simple life, and

181
00:09:20.000 --> 00:09:22.039
I think, you know, as a little bit of an aside,

182
00:09:22.039 --> 00:09:24.200
I think we're more likely to find simple life before

183
00:09:24.240 --> 00:09:28.519
we find complex life, just because of the amount of

184
00:09:28.559 --> 00:09:31.159
available real estate and the amount of available time. So

185
00:09:31.200 --> 00:09:32.879
if you look back at the history of the Earth,

186
00:09:33.600 --> 00:09:35.600
it seems to be accepted that we've had life on

187
00:09:35.639 --> 00:09:37.679
Earth for at least three and a half thousand million

188
00:09:37.799 --> 00:09:40.320
years old. Its fossils are found in the Pilburg in

189
00:09:40.360 --> 00:09:43.440
Western Australia. That's really kind of cool. We've only had

190
00:09:43.480 --> 00:09:46.039
complex life on Earth for about five hundred million years,

191
00:09:46.039 --> 00:09:48.200
so I think there are some studies this week I

192
00:09:48.240 --> 00:09:50.000
saw that suggest it might have been around a bit

193
00:09:50.039 --> 00:09:52.639
longer than that. So what that means is if you

194
00:09:52.679 --> 00:09:55.759
could do something really bizarre and make a dice with

195
00:09:55.840 --> 00:09:58.240
seven sides, which I've had somebody tell me is almost

196
00:09:58.240 --> 00:10:00.879
impossible to do, but you know, get a seven sided

197
00:10:00.919 --> 00:10:04.399
die instead of a six sided die and roll that die.

198
00:10:04.799 --> 00:10:06.600
You're looking at the Earth at some point in that

199
00:10:06.639 --> 00:10:09.519
three and a half billion year period, and only if

200
00:10:09.559 --> 00:10:11.360
you roll a seven would you see the Earth when

201
00:10:11.360 --> 00:10:14.159
there was complex life. So six times out of seven

202
00:10:14.200 --> 00:10:16.960
yard hitters when there's simple life. The other side of

203
00:10:17.039 --> 00:10:18.960
it is if you look at the habitats that life

204
00:10:19.000 --> 00:10:22.240
occupies on Earth, you know there are a far, far,

205
00:10:22.360 --> 00:10:25.799
far far greater amount of habitats where simple life can

206
00:10:25.840 --> 00:10:28.879
thrive than where complex life can thrive. You know, if

207
00:10:28.879 --> 00:10:30.960
I took you up to forty thousand feet and let go,

208
00:10:31.080 --> 00:10:33.200
you wouldn't so much fly as plummet in the immortal

209
00:10:33.200 --> 00:10:36.159
words munty python, but we find bacteria up there. If

210
00:10:36.200 --> 00:10:38.799
I drop you in, you know, one of the superheated

211
00:10:38.879 --> 00:10:41.679
lakes in Yellowstone, you'd dissolve quicker than people could pull

212
00:10:41.720 --> 00:10:43.399
you out, and that would be pleasant. But we find

213
00:10:43.480 --> 00:10:47.159
bacteria there. So there are far there's a far wider

214
00:10:47.279 --> 00:10:50.519
envelope of environments where you could find simple life than

215
00:10:50.559 --> 00:10:53.600
where you'd find complex life. All of that is based

216
00:10:53.639 --> 00:10:55.840
on the caveat that we're looking at life like Earth

217
00:10:55.919 --> 00:10:58.919
life of God, and that's a very big caveat. Is

218
00:10:59.240 --> 00:11:02.080
an assumption that is implicit in what most people discuss,

219
00:11:02.600 --> 00:11:04.559
and I think it's important to make it explicit. You

220
00:11:04.600 --> 00:11:08.159
watch Star Trek and you imagine multen metal men wandering

221
00:11:08.159 --> 00:11:10.679
around on magma planets and things like this, and intelligent

222
00:11:10.759 --> 00:11:14.200
hydrogen clouds. But when we're looking for things like life,

223
00:11:14.240 --> 00:11:16.039
it makes more sense to look for something we know

224
00:11:16.200 --> 00:11:20.519
can exist than for something that we could speculate might exist.

225
00:11:21.200 --> 00:11:23.200
And so we know of Earth life, so that forms

226
00:11:23.240 --> 00:11:25.600
our first template, and that will inform our first search.

227
00:11:26.159 --> 00:11:28.039
Even though you'd admit that there could be other kinds

228
00:11:28.080 --> 00:11:31.840
of life out there, and with Earth life as a template,

229
00:11:32.440 --> 00:11:34.200
you'd argue that for most of the time there's been

230
00:11:34.320 --> 00:11:36.879
life on Earth, we only have simple life. And in

231
00:11:36.919 --> 00:11:39.639
most of the places and environments you can find life

232
00:11:39.639 --> 00:11:42.200
on Earth, you can only find simple life. So that

233
00:11:42.279 --> 00:11:44.559
suggests to me simple life will be more common than

234
00:11:44.559 --> 00:11:47.320
complex life and the cosmos, and we're more likely to

235
00:11:47.320 --> 00:11:50.399
find that. Of course, that Zafemer saying that the only

236
00:11:50.440 --> 00:11:52.399
prediction you can make that is accurate is that all

237
00:11:52.399 --> 00:11:55.360
predictions will be wrong. So when we do find life,

238
00:11:55.919 --> 00:11:58.679
please don't shout at me. But that's kind of where

239
00:11:58.720 --> 00:12:01.519
I take it. But the coming back to the story,

240
00:12:01.799 --> 00:12:05.639
after I get derailed and go on a diversion, this

241
00:12:05.720 --> 00:12:07.960
story is looking at the other way, we can search

242
00:12:08.000 --> 00:12:12.480
for life, which is the one that has the potential

243
00:12:12.519 --> 00:12:15.960
for greater reward and greater excitement, but a lower potential

244
00:12:16.000 --> 00:12:19.879
for success, and that's a search for extraterrescural intelligence or

245
00:12:19.960 --> 00:12:25.200
SETI or the associated search for extraterreassural technology. So this

246
00:12:25.399 --> 00:12:28.679
is looking instead of looking for any life, it's looking

247
00:12:28.679 --> 00:12:32.120
for life that has technology at least as advanced as ours,

248
00:12:33.080 --> 00:12:35.759
that is in some way making itself known to the cosmos.

249
00:12:37.039 --> 00:12:39.240
Now in some degree, I've heard this described as searching

250
00:12:39.240 --> 00:12:40.960
for a needle in a haystack when you don't know

251
00:12:41.000 --> 00:12:42.919
what a haystack is and you've never seen a needle.

252
00:12:43.679 --> 00:12:49.840
It's trying to listen for something that another species that

253
00:12:49.919 --> 00:12:53.000
has technology would create that we could identify as being

254
00:12:53.039 --> 00:12:56.559
definitively caused by life. And because a bit like the

255
00:12:56.559 --> 00:12:59.840
science fiction analogy earlier on, we can imagine a wide

256
00:13:00.000 --> 00:13:02.679
variety of things, what this kind of work tends to

257
00:13:02.720 --> 00:13:07.360
do is focus on the things that we as humanity

258
00:13:07.440 --> 00:13:09.879
do that we could detect if we were elsewhere in

259
00:13:09.919 --> 00:13:13.480
the cosmos with sufficiently advanced technology. And the one that

260
00:13:13.519 --> 00:13:16.559
often gets a hat hung on it and said, this

261
00:13:16.600 --> 00:13:19.759
is one we'll look at is a search for broadcasts.

262
00:13:20.159 --> 00:13:22.240
I guess like this podcast is. When it goes out

263
00:13:22.279 --> 00:13:25.000
on ABC and it's broadcast on the radio bits of it,

264
00:13:25.679 --> 00:13:28.639
then that's been broadcast in all directions with a certain

265
00:13:28.679 --> 00:13:30.679
amount of power so that when somebody tunes in the

266
00:13:30.720 --> 00:13:33.360
car they can listen to it. And that means that

267
00:13:34.080 --> 00:13:37.080
this broadcast will be winging its way out into space,

268
00:13:37.120 --> 00:13:40.960
and somebody with a sufficiently sensitive radio receiver pointed at

269
00:13:40.960 --> 00:13:43.159
the Earth at just the right time could tune in

270
00:13:43.240 --> 00:13:45.799
and tell me that I'm talking rubbish. Essentially, that's probably

271
00:13:45.799 --> 00:13:48.159
what would happen, or the churn over and say, look,

272
00:13:48.200 --> 00:13:50.559
please don't cancel neighbors. You know that needs to run

273
00:13:50.600 --> 00:13:55.320
on and on and on. Now you make an assumption

274
00:13:55.600 --> 00:14:00.440
that other technologically advanced species, if they exist, would follow

275
00:14:00.480 --> 00:14:03.679
a similar technology route to us, then that suggests that

276
00:14:03.720 --> 00:14:06.080
there'll be a period of time when those species too,

277
00:14:06.279 --> 00:14:10.039
broadcast to the cosmos. Now, the analogy I use a

278
00:14:10.080 --> 00:14:11.799
little bit here is a bit like a toddler in

279
00:14:11.840 --> 00:14:16.120
a cave screaming its lungs out. Eventually they'll learn to

280
00:14:16.200 --> 00:14:18.679
control themselves. So we're already finding on Earth that we

281
00:14:18.759 --> 00:14:21.639
are throwing less signal into space, and we used to

282
00:14:21.679 --> 00:14:24.120
because it's more efficient to broadcast point to point are

283
00:14:24.159 --> 00:14:26.720
through cables. So a lot of people will listen to

284
00:14:26.759 --> 00:14:30.519
this through their wired Internet that comes through cables or

285
00:14:30.600 --> 00:14:33.840
through Heaven for fens, through stalink where it's point to points,

286
00:14:33.840 --> 00:14:37.360
so there's not much wasted and so eventually people are

287
00:14:37.360 --> 00:14:40.519
predicting the Earth will go radio acquired again. But this

288
00:14:40.679 --> 00:14:42.919
is one way that we know we as a society

289
00:14:43.639 --> 00:14:47.600
are making ourselves obvious to aliens that are out there,

290
00:14:47.759 --> 00:14:49.679
if they exist and if they've got the technology to

291
00:14:49.720 --> 00:14:52.399
listen in So that has inspired a lot of people

292
00:14:52.440 --> 00:14:55.759
to turn the telescope skyward with radio telescopes and listen

293
00:14:55.799 --> 00:14:58.519
to see if we can get alien signals. And that's

294
00:14:58.559 --> 00:15:02.720
been fundamentally what set he is. It's been really useful

295
00:15:02.720 --> 00:15:05.360
to us in the Australian astronomy community. Exit's the many

296
00:15:05.360 --> 00:15:08.639
reason that the Parks Radio Telescope is still operating. Curtsey

297
00:15:08.679 --> 00:15:11.960
of the breakthrough a listening initiative. But people have been

298
00:15:12.000 --> 00:15:14.960
listening and they've tried listening at all sorts of different frequencies.

299
00:15:15.440 --> 00:15:18.159
They've done targeted searchers looking at a few stars like

300
00:15:18.200 --> 00:15:22.799
the Sun. They've also piggybacked off other surveys where people

301
00:15:22.799 --> 00:15:26.279
are getting radio observations for a totally different reason, and

302
00:15:26.360 --> 00:15:28.879
the SETI people get hold of those observations and check

303
00:15:28.960 --> 00:15:31.480
them just to see to see whether there's a TV

304
00:15:31.559 --> 00:15:35.240
broadcast buried in that essentially. But the challenge of doing

305
00:15:35.240 --> 00:15:38.759
this historically is that it's very labor intensive because there's

306
00:15:38.759 --> 00:15:41.200
a lot of different radio sources out there that are

307
00:15:41.519 --> 00:15:44.120
natural and you need to rule them out. You find

308
00:15:44.120 --> 00:15:47.200
a signal, it looks weird, but if it's natural, it's

309
00:15:47.240 --> 00:15:49.559
not aliens, so you've got to rule that out. You've

310
00:15:49.600 --> 00:15:53.200
then got a whole heap of you know, human generated

311
00:15:53.240 --> 00:15:55.679
signals that you've got to rule out, and they can

312
00:15:55.720 --> 00:15:58.279
be harder because it could be Spice satellites gone through

313
00:15:58.639 --> 00:16:00.399
and nobody's going to set to you will actually know

314
00:16:01.000 --> 00:16:03.279
you've called us. That was my spiceack, like we were

315
00:16:03.960 --> 00:16:05.799
trying to watch them filming neighbors. I don't know why

316
00:16:05.799 --> 00:16:07.360
I've got NIBBs on the man, given that I've never

317
00:16:07.399 --> 00:16:11.879
watched the thing, but there you go. I think that's

318
00:16:11.919 --> 00:16:13.600
what it is. I saw that story and given them

319
00:16:13.639 --> 00:16:15.960
my joke about, you know, searching for aliens. Is that

320
00:16:16.000 --> 00:16:17.519
they'll come and tell us to turn it off and

321
00:16:17.519 --> 00:16:19.879
stop it. It seems ironic, but anyway, you know, it

322
00:16:19.879 --> 00:16:21.679
could be a spicack like looking down. It could be

323
00:16:21.720 --> 00:16:23.759
as simple as a microwave in the next building that

324
00:16:23.799 --> 00:16:26.320
somebody was warming their dinner up. And that has actually

325
00:16:26.320 --> 00:16:30.440
happened before. People has detected microwaves in other buildings. So

326
00:16:30.480 --> 00:16:32.960
it's really really complicated. And what that means is that

327
00:16:33.039 --> 00:16:36.399
a lot of these efforts to look for alien technology

328
00:16:36.399 --> 00:16:39.159
and alien signals have been limited by the human resources

329
00:16:39.159 --> 00:16:43.759
available to them, which brings us finally to this new survey.

330
00:16:43.799 --> 00:16:45.480
And I know I've gone in a very long roundabout

331
00:16:45.519 --> 00:16:49.600
route there there's this incredible radio facility called the Very

332
00:16:49.679 --> 00:16:53.879
Large Array over in the US that the square kilometer

333
00:16:54.000 --> 00:16:55.480
Array is going to be bigger and better, and we're

334
00:16:55.519 --> 00:16:57.120
going to have that in Australia, so we can wear

335
00:16:57.159 --> 00:16:59.600
a flag and say, well who but the Very Large

336
00:16:59.679 --> 00:17:02.600
Arrays been doing incredible observations for a very long time.

337
00:17:02.759 --> 00:17:07.160
If I remember correctly, those who like the movie Contact,

338
00:17:07.440 --> 00:17:10.039
which is based on the Calsagen book, some of the

339
00:17:10.039 --> 00:17:12.880
scenes were shot at the veryl Argirae if I remember right.

340
00:17:12.920 --> 00:17:15.720
So if I'm wrong again, please don't shout too loudly,

341
00:17:15.759 --> 00:17:18.359
but my memory is that that's the vertyl Argerira that

342
00:17:18.400 --> 00:17:19.519
featured in that film.

343
00:17:19.839 --> 00:17:20.079
Yeah.

344
00:17:20.119 --> 00:17:23.839
Anyway, the Vinyl Largirae has spent a huge amount of

345
00:17:23.880 --> 00:17:27.400
time scanning, particularly the Northern Hemisphere sky because it's a

346
00:17:27.440 --> 00:17:31.920
Northern Hemisphere facility, doing all sorts of radio astronomy observations

347
00:17:31.960 --> 00:17:36.359
of all sorts of things. A team has developed something

348
00:17:36.440 --> 00:17:40.000
that they call Cosmic. Now I'm just finding the acronym here.

349
00:17:40.160 --> 00:17:47.839
Cosmic is a commensal open source multimode interferometric cluster, which

350
00:17:47.880 --> 00:17:49.839
is a mouthful, which is why they call it cosmic.

351
00:17:50.319 --> 00:17:54.799
It's a very large computer and software setup that essentially

352
00:17:54.799 --> 00:17:58.359
attempts to automate that complex process that I described where

353
00:17:58.400 --> 00:18:00.759
you've got to rule out all of the posts signals.

354
00:18:01.480 --> 00:18:04.079
It's been heavily built and coded so that every single

355
00:18:04.079 --> 00:18:08.240
observation that they get, they can run through this pipeline

356
00:18:08.759 --> 00:18:10.480
and it will say, does it have anything in it

357
00:18:10.519 --> 00:18:13.279
that could look like it's of an alien origin? Filter

358
00:18:13.359 --> 00:18:16.759
it down heavily. If it passes that first test, then

359
00:18:16.759 --> 00:18:19.720
you run another test that said, could any astronomical phenomenon

360
00:18:19.759 --> 00:18:23.759
explain this? If it fails that test, it gets thrown out.

361
00:18:23.960 --> 00:18:25.920
Next it says, could it be anything that we know

362
00:18:26.000 --> 00:18:29.039
of that is of human origin, and if it fails

363
00:18:29.039 --> 00:18:31.880
that test, it's thrown out. So it filters it down

364
00:18:31.920 --> 00:18:34.759
to give the people who do the checking a tiny

365
00:18:34.799 --> 00:18:39.279
shortlist rather than an incredible long list. Now doing that,

366
00:18:40.119 --> 00:18:44.160
they've been able to take nine hundred and twenty thousand

367
00:18:44.839 --> 00:18:48.640
different observational pointings from the very large array. That's nine

368
00:18:48.759 --> 00:18:52.680
hundred and twenty thousand different radio observations of different parts

369
00:18:52.680 --> 00:18:55.640
of the night sky and analyze them one after another

370
00:18:55.759 --> 00:18:59.480
looking for any signal of aliens. And this does clever things.

371
00:18:59.519 --> 00:19:02.640
It looks for a signal that is localized on the sky,

372
00:19:02.720 --> 00:19:04.880
so it looks like it's coming from one particular star.

373
00:19:05.599 --> 00:19:07.920
It even looks to check for the red shift and

374
00:19:07.960 --> 00:19:09.839
the blue shift of that signal, because if it's on

375
00:19:09.880 --> 00:19:12.960
a planet going around that star, the frequency will change

376
00:19:13.000 --> 00:19:14.799
a little bit as a result of the planet's movement

377
00:19:14.799 --> 00:19:17.319
around the star. So it digs into a whole heap

378
00:19:17.359 --> 00:19:21.599
of things to do these filters and allows them to

379
00:19:21.599 --> 00:19:24.079
throw a lot of things away. So this has served

380
00:19:24.200 --> 00:19:26.960
eighty two percent of the entire northern hemispherre nite sky,

381
00:19:27.079 --> 00:19:30.440
like actually nine hundred and fifty thousand pointings of the telescope,

382
00:19:30.960 --> 00:19:33.640
and what they've found was they've flagged a few interesting signals.

383
00:19:33.880 --> 00:19:36.319
None of them turn out to be aliens. So after

384
00:19:36.319 --> 00:19:40.240
all this work, after all this waffle, after all my diversions,

385
00:19:40.279 --> 00:19:44.559
the result is we've found nothing. But that's the risky run,

386
00:19:44.599 --> 00:19:48.319
because at the end of the day, if technologically advanced

387
00:19:48.359 --> 00:19:50.799
life is out there, there's no guarantee it will broadcast

388
00:19:50.839 --> 00:19:53.559
this way. As I said earlier on, we're probably going

389
00:19:53.640 --> 00:19:56.519
to be radio quiet again within just a few decades,

390
00:19:56.559 --> 00:19:59.880
even if we don't wipe ourselves out, so we'll stop broke.

391
00:20:00.599 --> 00:20:02.920
So then there'll be a single little shell of radio

392
00:20:02.920 --> 00:20:07.400
emissions about one hundred light years wide, expanding into specially

393
00:20:07.440 --> 00:20:09.599
on the Sun. And if you're in that one hundred

394
00:20:09.680 --> 00:20:12.039
year window, you'll be able to tune in and listen

395
00:20:12.079 --> 00:20:15.119
to us. If you're too early or too late. You

396
00:20:15.160 --> 00:20:17.599
want here now. One hundred years it's a long time

397
00:20:17.599 --> 00:20:19.000
to me and you, and I'd love to think how

398
00:20:19.079 --> 00:20:21.880
last one hundred years on this planet. But in the

399
00:20:21.880 --> 00:20:24.240
scale of the cosmos, our Earth has had life on

400
00:20:24.279 --> 00:20:27.200
it for three and a half thousand million years, and

401
00:20:27.279 --> 00:20:30.480
only for one hundred years of that has the Earth

402
00:20:30.480 --> 00:20:32.720
had a signal. So that's a one in thirty five

403
00:20:32.799 --> 00:20:36.119
million chance of looking at Earth while it's have life

404
00:20:36.680 --> 00:20:40.200
and hearing our radio broadcasts. And that's the lower odds

405
00:20:40.200 --> 00:20:41.240
than the asteroid hitting it is.

406
00:20:41.759 --> 00:20:48.000
Yeah, it's also lower odds are winning payable anyway.

407
00:20:48.160 --> 00:20:49.359
Yeah, it's an.

408
00:20:49.240 --> 00:20:50.160
Interesting story in that.

409
00:20:50.519 --> 00:20:53.880
Okay, Yeah, they've found a new way, but they haven't

410
00:20:53.880 --> 00:20:56.440
found anything yet, and they have had a lot of targets.

411
00:20:56.440 --> 00:21:01.920
But that doesn't mean it's not out there somewhere. It's

412
00:21:01.920 --> 00:21:05.759
not saying there isn't intelligent life. But I do agree

413
00:21:05.759 --> 00:21:08.880
with you that finding microbial life or single cell.

414
00:21:08.680 --> 00:21:10.200
Life of some kind.

415
00:21:11.440 --> 00:21:15.400
Is in the foreseeable future, and we've got missions headed

416
00:21:15.440 --> 00:21:15.720
out in.

417
00:21:17.319 --> 00:21:20.480
A very near future to try and find just that

418
00:21:20.799 --> 00:21:22.559
we do. We might even talk about those in the

419
00:21:22.640 --> 00:21:23.799
Q and A episode later on.

420
00:21:24.160 --> 00:21:26.160
We might do that.

421
00:21:26.839 --> 00:21:31.839
But the probability of finding life in our own solar

422
00:21:31.960 --> 00:21:35.279
system is pretty reasonable. I wouldn't like to put a

423
00:21:35.359 --> 00:21:38.119
number on it, but I think that the odds are

424
00:21:38.119 --> 00:21:43.400
pretty good. Fred also feels the same way. So even

425
00:21:43.519 --> 00:21:47.519
that would be one of the greatest discoveries in human history,

426
00:21:47.559 --> 00:21:51.319
because so far we only know one place where there

427
00:21:51.359 --> 00:21:58.400
is life, and that's us. So time will tell. But

428
00:21:59.559 --> 00:22:03.839
when they the super kella fregilistic array up and running,

429
00:22:04.039 --> 00:22:05.519
that might.

430
00:22:05.519 --> 00:22:08.680
Get and people will be applying these same kind of

431
00:22:08.680 --> 00:22:11.599
techniques to the square kilometer or I want it something now,

432
00:22:11.599 --> 00:22:14.079
because it's the obvious way to do things, especially when

433
00:22:14.119 --> 00:22:16.039
you've got good computing power. But I think the other

434
00:22:16.079 --> 00:22:20.400
thing this highlights, which I think astronomy in general does

435
00:22:20.480 --> 00:22:24.640
really really well, is the importance of reporting no results

436
00:22:24.720 --> 00:22:28.119
or negative results. Now, once upon a time of the

437
00:22:28.160 --> 00:22:30.400
distant past that dated a biologist, and there was a

438
00:22:30.400 --> 00:22:33.279
real problem in her field that when people did an

439
00:22:33.319 --> 00:22:36.799
experiment and they found nothing, they couldn't really get it published.

440
00:22:36.839 --> 00:22:39.599
Either the company that was sponsoring it wasn't very keen

441
00:22:39.640 --> 00:22:41.799
on them publishing it, or the journal said, well, look,

442
00:22:41.799 --> 00:22:44.599
you've not found anything, so we're not going to report it. Now,

443
00:22:44.680 --> 00:22:47.599
Let's say you do an experiment that isn't going to

444
00:22:47.680 --> 00:22:50.160
find anything, but it's not that accurate, so there's a

445
00:22:50.200 --> 00:22:54.279
small uncertainty in your results. You find nothing, you don't

446
00:22:54.279 --> 00:22:56.640
publish it. So someone else goes away and does the

447
00:22:56.640 --> 00:23:00.039
same experiment. They find nothing. But eventually, due to the

448
00:23:00.319 --> 00:23:03.720
where statistics worth. Someone might get a signal that looks

449
00:23:03.759 --> 00:23:08.400
interesting and they'll publish it, and you get a almost

450
00:23:08.440 --> 00:23:13.039
misleading idea of whether this thing happens or not, whether

451
00:23:13.079 --> 00:23:14.920
this thing works or not. And this was something that

452
00:23:14.960 --> 00:23:17.160
she was concerned with. She ended up leaving the field.

453
00:23:18.200 --> 00:23:20.079
And it's a real challenge that you're facing a lot

454
00:23:20.079 --> 00:23:22.880
of disciplines is that it is much much easier to

455
00:23:22.880 --> 00:23:26.799
publish a result that is explicitly, we found something, we

456
00:23:26.880 --> 00:23:29.240
observe something. There is a signal here, we found it.

457
00:23:29.680 --> 00:23:31.839
But publishing the opposite of that, which is we looked

458
00:23:31.880 --> 00:23:35.160
and found nothing, is very hard. And Astronomy has done

459
00:23:35.160 --> 00:23:37.079
and continues to do a really good job of people

460
00:23:37.119 --> 00:23:39.440
being able to publish the results when they find nothing.

461
00:23:39.759 --> 00:23:41.640
And we find this in the extra planet again, we

462
00:23:42.039 --> 00:23:44.720
observe a style. We don't find any planets, but will

463
00:23:44.759 --> 00:23:46.519
include it in a paper and we'll publish the data

464
00:23:46.559 --> 00:23:48.359
to say we watch the STAF for a decade and

465
00:23:48.400 --> 00:23:51.559
nothing happened. And the beauty is that makes that there

466
00:23:51.599 --> 00:23:54.400
to public It means that other people with similar levels

467
00:23:54.400 --> 00:23:57.759
of equipment towards don't waste their time, but it also

468
00:23:57.880 --> 00:24:00.480
means that you've got that data there, so somebody with

469
00:24:00.599 --> 00:24:04.240
higher resolution observations in future can use your dicta as

470
00:24:04.279 --> 00:24:06.960
well as part of their analysis. And it's a really

471
00:24:07.000 --> 00:24:09.359
critical part of science to be able to report what

472
00:24:09.440 --> 00:24:12.519
you didn't find. And I think it doesn't occur to

473
00:24:12.559 --> 00:24:14.319
me that often, but there's a certain amount of pride,

474
00:24:14.359 --> 00:24:17.839
I think in the fact that astronomy remains a discipline

475
00:24:17.880 --> 00:24:20.000
where you can try to look for something and fail

476
00:24:20.519 --> 00:24:22.799
and still get your work published and still progress your

477
00:24:22.799 --> 00:24:26.759
career because you've still advanced our knowledge because you've lowered

478
00:24:26.759 --> 00:24:30.240
the possibilities or you've lowered the fair space of what

479
00:24:30.319 --> 00:24:32.000
could be by ruling out what can't be.

480
00:24:33.079 --> 00:24:37.319
And there's also the fact that what we're witnessing now

481
00:24:37.440 --> 00:24:41.480
is new studies and new papers being published based on

482
00:24:42.240 --> 00:24:48.720
historical data, historical gathering of information, and they hadn't been

483
00:24:48.759 --> 00:24:51.680
able to analyze it the way they can now because

484
00:24:51.720 --> 00:24:54.000
the technology has improved, So they've been able to do

485
00:24:54.079 --> 00:24:58.200
studies now based on information that was published twenty thirty

486
00:24:58.279 --> 00:25:01.480
years ago when the technolog he was far inferior.

487
00:25:01.640 --> 00:25:04.200
So you can you know, you can.

488
00:25:04.160 --> 00:25:07.240
Use those those papers for.

489
00:25:08.839 --> 00:25:11.920
Yeah, And that's the probably we wilcome back to with

490
00:25:12.039 --> 00:25:15.480
our final story in this, I think so. I also

491
00:25:15.519 --> 00:25:16.839
see that Fred has returned.

492
00:25:17.400 --> 00:25:19.599
Hello Fred Watson, here he is.

493
00:25:20.200 --> 00:25:22.000
Hello, how are you, gentlemen?

494
00:25:22.680 --> 00:25:24.400
We are, well, it's nice to see you.

495
00:25:24.440 --> 00:25:26.079
When you you were going to drop in, we thought

496
00:25:26.079 --> 00:25:29.640
we'd just surprise everyone. We didn't pre empt it because

497
00:25:29.680 --> 00:25:31.839
I also considered the possibility you might forgot.

498
00:25:32.200 --> 00:25:35.440
Yes, I considered that as well. Jetlag does funny things

499
00:25:35.440 --> 00:25:36.000
to your brain.

500
00:25:37.519 --> 00:25:38.279
Indeed it does.

501
00:25:39.240 --> 00:25:41.240
You came in right at the end of this story.

502
00:25:41.279 --> 00:25:43.759
And if you'd like to read up on that search

503
00:25:43.759 --> 00:25:47.319
for extraterrestrials, the new way of doing it that has

504
00:25:47.319 --> 00:25:53.359
found nothing yet, you can do that at space dot com.

505
00:25:53.359 --> 00:25:54.359
Okay, we tacked.

506
00:25:56.279 --> 00:26:02.160
Spaces all right, Fred, you gonna sort of why don't

507
00:26:02.200 --> 00:26:04.759
we Why don't we throw to you now that you're

508
00:26:04.799 --> 00:26:06.599
back and you can tell us a little bit about

509
00:26:06.640 --> 00:26:09.880
your trip because you've been away for it feels like

510
00:26:09.920 --> 00:26:11.960
four or five years.

511
00:26:12.119 --> 00:26:16.400
No offense, Joddy, that was just one answer from me.

512
00:26:17.279 --> 00:26:25.640
Yeah, okay, well I want to go there. But the yes,

513
00:26:25.720 --> 00:26:32.519
the trip was pretty hard work actually, because we were

514
00:26:32.680 --> 00:26:35.240
many and I were leading one of her tour, actually

515
00:26:35.240 --> 00:26:38.559
three of her tours, three separate ones, which were all

516
00:26:38.599 --> 00:26:43.160
back to back. We started off in Sweden, went to

517
00:26:43.880 --> 00:26:47.079
far northern Sweden, far northern Norway for the first time.

518
00:26:47.119 --> 00:26:50.920
I got to the North Cape, a latitude of seventy

519
00:26:50.960 --> 00:26:52.880
one degrees, so farthest north I've.

520
00:26:52.799 --> 00:26:53.680
Ever been, I think.

521
00:26:54.759 --> 00:26:58.640
Then we went down back down to Oslo, flew across

522
00:26:58.640 --> 00:27:05.119
to Requivic and had a really wet and snowy ten

523
00:27:05.200 --> 00:27:08.119
days I think it was eleven days in Iceland again

524
00:27:08.160 --> 00:27:11.519
going to bits of Iceland that I'd never seen, the

525
00:27:11.559 --> 00:27:17.319
Northwest in particular, some quite extraordinary places there, including one

526
00:27:17.319 --> 00:27:21.440
of the highlights was the place where astronauts used to

527
00:27:21.480 --> 00:27:25.599
go to train in the Apollo era to train in geology,

528
00:27:25.680 --> 00:27:30.720
and there's a little museum there. It's basically a small

529
00:27:30.799 --> 00:27:36.839
town at the end of the road, almost not very

530
00:27:36.920 --> 00:27:40.000
much to recommend it under normal circumstances, but this amazing

531
00:27:40.079 --> 00:27:43.720
museum and they get visits very frequently from past and

532
00:27:43.759 --> 00:27:47.599
present astronauts, which is fabulous. It was a great experience.

533
00:27:48.519 --> 00:27:53.240
And then we went from Reki Victor Nook in Greenland,

534
00:27:53.319 --> 00:27:56.839
where we spent the last eleven days of our tour.

535
00:27:57.480 --> 00:28:02.519
Greenland is a totally fascinating place in every possible way.

536
00:28:02.559 --> 00:28:06.599
It is stunning physically, you have an ice sheet which

537
00:28:06.640 --> 00:28:10.519
we stood right at the edge of a few coastal

538
00:28:10.559 --> 00:28:14.200
towns and wait for this, no roads between them, not

539
00:28:14.319 --> 00:28:21.319
at all. All trans transport between towns in Greenland is

540
00:28:21.359 --> 00:28:24.440
either by boat or by air, and we did it

541
00:28:24.480 --> 00:28:30.000
by air. So yeah, some amazing stuff. What drove the trip,

542
00:28:30.119 --> 00:28:33.559
of course, were the chance to see sites like the

543
00:28:33.599 --> 00:28:39.880
Northern Lights, chance to walk on glaciers in Iceland and

544
00:28:40.000 --> 00:28:45.599
stand beside active volcanoes. And the thing that blew my

545
00:28:45.720 --> 00:28:50.359
mind in Greenland were the icebergs. Just astonishing, these, you know,

546
00:28:50.640 --> 00:28:53.599
half kilometer long lumps of ice floating past our hotel

547
00:28:53.640 --> 00:29:02.599
window as they carved off the theluly Sat was the

548
00:29:02.799 --> 00:29:03.319
name of the.

549
00:29:03.200 --> 00:29:05.279
Town where we were at that time.

550
00:29:05.440 --> 00:29:08.359
At the end of the ill, I can't say the

551
00:29:08.400 --> 00:29:11.960
word iluli Sat Fjord. Right at the other end of

552
00:29:12.000 --> 00:29:14.200
it is the Greenland ice sheet, and it carves off

553
00:29:14.240 --> 00:29:18.480
all these icebergs as you see them go past the

554
00:29:19.240 --> 00:29:22.759
I guess. The other highlight was, particularly in northern Norway

555
00:29:22.880 --> 00:29:27.079
and Sweden, and also again in Greenland, some fabulous sightings

556
00:29:27.079 --> 00:29:30.640
of the Aurora borealis. We had some great times with that,

557
00:29:31.279 --> 00:29:35.200
wonderful images taken by our whole group and I got

558
00:29:35.279 --> 00:29:39.039
quite a few as well, using sad to say one

559
00:29:39.079 --> 00:29:41.000
of these, it's just believable.

560
00:29:42.279 --> 00:29:45.160
They did take amazing pictures. I saw a couple that

561
00:29:45.160 --> 00:29:46.200
you posted early in your car.

562
00:29:46.279 --> 00:29:48.960
Oh good, Yeah, yeah, forgotten I've done that. It's five

563
00:29:49.000 --> 00:29:51.960
and a half weeks and so it's been a long time.

564
00:29:52.200 --> 00:29:55.799
It's been hard work looking after these wonderful customers that

565
00:29:55.799 --> 00:29:59.559
we have, some of whom might be listening to this

566
00:30:00.880 --> 00:30:03.920
because a lot of our clients sort of came to

567
00:30:04.000 --> 00:30:08.519
us through Space Notes. They're all fabulous people. We've enjoyed

568
00:30:08.640 --> 00:30:12.799
their company throughout three different groups, one or two people

569
00:30:12.880 --> 00:30:16.519
in common throughout both of them, and had a great time.

570
00:30:17.480 --> 00:30:21.960
The one who listened during my absence was telling me

571
00:30:22.279 --> 00:30:25.279
how great they thought John t is. So that was

572
00:30:25.359 --> 00:30:27.799
good news because that's why we asked him to do

573
00:30:27.920 --> 00:30:28.319
the gig.

574
00:30:29.039 --> 00:30:30.799
Yeah, the checks in the past, Fred, thank you.

575
00:30:33.519 --> 00:30:33.759
Yeah.

576
00:30:33.839 --> 00:30:38.079
So hard work but very enjoyable, and I have to

577
00:30:38.119 --> 00:30:41.119
say many and I are sort of now recovering and

578
00:30:41.240 --> 00:30:44.240
facing the next big thing, which is a Dark Sky

579
00:30:44.319 --> 00:30:47.160
conference in Melbourne in about two weeks time. So there's

580
00:30:47.559 --> 00:30:51.240
twenty people coming to that and we'll be talking about

581
00:30:51.279 --> 00:30:52.119
all that kind of thing.

582
00:30:52.599 --> 00:30:56.519
Yeah, Judy and I will be in Greenland and Iceland

583
00:30:56.599 --> 00:30:59.359
later this year, so we're really looking forward to it.

584
00:30:59.440 --> 00:31:01.079
We're actually doing in an Iceberg tour.

585
00:31:01.319 --> 00:31:03.839
Yeah, and on I don't know what kind of bird

586
00:31:03.880 --> 00:31:06.400
it is, probably one that'll get me wet, but yeah,

587
00:31:06.559 --> 00:31:08.519
really looking really looking forward to that.

588
00:31:09.119 --> 00:31:11.079
See, I think you should set the next trip or

589
00:31:11.119 --> 00:31:14.319
one of the future trips for that to coincide with

590
00:31:14.359 --> 00:31:17.279
Germinid Maximum as well. So Germanids are obviously the highlight

591
00:31:17.319 --> 00:31:21.680
of the year for everything, and being in December, that's

592
00:31:21.759 --> 00:31:24.759
perfect dark skytime so you could sit out under the

593
00:31:24.799 --> 00:31:26.960
northern light, sancy natural fireworks as well.

594
00:31:27.759 --> 00:31:31.960
There's always a special reason for watching the Germanids, John

595
00:31:31.960 --> 00:31:33.920
t which you might not be aware of, but they

596
00:31:33.960 --> 00:31:39.519
peak on my birthday, so it's it's a natural it's

597
00:31:39.519 --> 00:31:40.960
a natural birthday prison.

598
00:31:41.680 --> 00:31:43.920
Yeah, and they've just got met and beter and better

599
00:31:44.039 --> 00:31:45.799
as well, because I mean, I know when I was

600
00:31:45.839 --> 00:31:48.160
watching them in the nineties they were very, very good,

601
00:31:49.200 --> 00:31:52.119
and they're still getting better on a decadal basis because

602
00:31:52.119 --> 00:31:55.920
see media streams gradually talking round and we're still what's

603
00:31:55.920 --> 00:31:58.039
seeing the best of them, so they're still improving.

604
00:31:58.240 --> 00:32:01.759
Yeah, yeah, there you go. So just one final comment

605
00:32:01.799 --> 00:32:05.599
from me, if I may, Andrew, and that is thanks

606
00:32:05.640 --> 00:32:08.880
to both of you for holding the floor so well

607
00:32:09.880 --> 00:32:12.759
and especially john Ty for jumping into the hot seat.

608
00:32:12.880 --> 00:32:13.279
It was.

609
00:32:13.519 --> 00:32:18.920
It's been absolutely, absolutely terrific you, you know, being being

610
00:32:19.079 --> 00:32:23.279
our favorite depth and stand by and we look forward

611
00:32:23.359 --> 00:32:27.559
to welcoming you back in them.

612
00:32:27.680 --> 00:32:30.440
Glad you had a good break. That sounds it was.

613
00:32:30.519 --> 00:32:33.759
It's been great. It's been cope with Johnny.

614
00:32:34.200 --> 00:32:37.960
It's all right, okay, well you down all slope the

615
00:32:38.559 --> 00:32:40.480
nice and at seven o'clock in the morning.

616
00:32:42.279 --> 00:32:46.960
He's been terrific, he really has, despite the bad poetry

617
00:32:47.000 --> 00:32:49.279
I throw it. I throwed him from time to time. Yes,

618
00:32:52.200 --> 00:32:54.039
you know, stick around or you got to go.

619
00:32:54.799 --> 00:32:57.720
If I may, I'll stick around. But it's john Ty's gig.

620
00:32:57.880 --> 00:33:00.000
I'm just going to sit in the background and enjoy it.

621
00:33:00.279 --> 00:33:03.039
That's all right, Yeah, all right, Well we're going to

622
00:33:03.039 --> 00:33:05.640
do We're talking now about Johnny's favorite punching bag and

623
00:33:05.680 --> 00:33:08.759
that is Spacex' what's the latest with them?

624
00:33:09.279 --> 00:33:12.359
Yeah. I always, and I say this quite often, I

625
00:33:12.440 --> 00:33:15.000
try and take felly even handed side of things when

626
00:33:15.000 --> 00:33:17.200
I talk about Elon Musk and SpaceX and what they

627
00:33:17.200 --> 00:33:20.279
do because I think it's like all good characters in books.

628
00:33:20.319 --> 00:33:22.559
The best characters are not evil or good, but they're

629
00:33:22.559 --> 00:33:24.720
somewhere in between, and they do good things and bad things.

630
00:33:25.319 --> 00:33:28.200
But this week I think we're talking more about the

631
00:33:28.240 --> 00:33:32.079
things that haven't quite worked right. So earlier on I

632
00:33:32.079 --> 00:33:36.119
think possibly the first episode I was substituting in, we

633
00:33:36.200 --> 00:33:39.880
talked about the starship launch that went wrong and everything

634
00:33:39.880 --> 00:33:44.119
went boom and fragments fell over the Turks and Caicos islands.

635
00:33:44.200 --> 00:33:47.880
And interestingly, there is a link to a pretty lengthy

636
00:33:47.880 --> 00:33:50.839
and quite startling article on CNN which we might be

637
00:33:50.880 --> 00:33:53.480
able to put out with the podcasts. From the thirtieth

638
00:33:53.599 --> 00:33:55.559
of January. I'd not really followed up on it, but

639
00:33:55.640 --> 00:33:59.400
people in the Turks and Caicos were complaining about the

640
00:33:59.480 --> 00:34:02.160
lack of engagement from SpaceX, the fact that they're finding

641
00:34:02.240 --> 00:34:04.599
debris all over the place. A car was damaged by

642
00:34:04.599 --> 00:34:06.960
some of it, and loads of it floating and washing

643
00:34:07.000 --> 00:34:09.519
up on the beaches, and nobody's made any efforts to

644
00:34:09.559 --> 00:34:12.599
contact them or collect any or do the cleanup. Now

645
00:34:12.599 --> 00:34:16.039
that may have changed. SpaceX has historically been reasonably good

646
00:34:16.039 --> 00:34:19.119
at cleaning up its mess, but I was quite solid

647
00:34:19.320 --> 00:34:24.719
reading that article through the level to which there was

648
00:34:24.719 --> 00:34:27.199
a bit of upset there, and that the photographs of

649
00:34:27.239 --> 00:34:30.559
all this debris washing up on the beaches was quite startling,

650
00:34:30.639 --> 00:34:32.440
when in the days after that it was just said,

651
00:34:32.440 --> 00:34:34.239
oh it fell in the Atlantic, it went over the

652
00:34:34.559 --> 00:34:37.280
and kcos but it was out in open ocean, so

653
00:34:37.360 --> 00:34:39.519
that was quite sobering. But I only came across that

654
00:34:39.760 --> 00:34:43.719
because see there was another high profile SpaceX. Things didn't

655
00:34:43.719 --> 00:34:46.480
work as expected. That's made a lot of the news

656
00:34:46.519 --> 00:34:49.320
over the last week, particularly on the BBC website, but

657
00:34:49.440 --> 00:34:53.559
also on space dot com fabulous images again all over

658
00:34:54.039 --> 00:34:56.760
the app formly known as Twitter, and all over Blue

659
00:34:56.800 --> 00:35:01.159
Sky and things like this. Because one of SpaceX's falk

660
00:35:01.159 --> 00:35:05.960
and nine rockets, the upper stages of those are not reusable.

661
00:35:06.199 --> 00:35:08.239
These are the bits that go so high they can't

662
00:35:08.239 --> 00:35:11.199
just bring them back and land them, and typically they

663
00:35:11.880 --> 00:35:14.280
bring them back in a controlled re entry. So they say,

664
00:35:14.960 --> 00:35:16.480
this thing is going to come back to worth, but

665
00:35:16.519 --> 00:35:18.519
we're going to force it to the orbit at a time.

666
00:35:18.639 --> 00:35:20.480
We want it to in a place where it's going

667
00:35:20.519 --> 00:35:23.400
to be far from land, keeping it as safe as possible.

668
00:35:24.079 --> 00:35:26.639
But this one in particular failed to come back in

669
00:35:26.679 --> 00:35:29.119
at the start of February and had gone out of control.

670
00:35:29.519 --> 00:35:31.320
So everybody knew it was going to come back in

671
00:35:31.519 --> 00:35:34.880
at some point at some time in some place, but

672
00:35:34.920 --> 00:35:37.599
nobody was really sure why. So it's like your typical

673
00:35:37.719 --> 00:35:40.159
failed attempt at being menacing. You know, at some time,

674
00:35:40.239 --> 00:35:43.480
at some place in the indeterminate future, something bad might

675
00:35:43.559 --> 00:35:47.599
possibly happen, maybe, and then it did. So there's all

676
00:35:47.639 --> 00:35:51.440
this footage from northern Europe, starting from kind of Lincolnshire

677
00:35:51.480 --> 00:35:54.800
in the UK of yet another one of these space

678
00:35:54.840 --> 00:35:59.159
Debruy re entry events. Spectacular, incredible scenes that people have shot,

679
00:35:59.360 --> 00:36:02.039
but the actually made it to the ground in fairly

680
00:36:02.079 --> 00:36:05.960
substantial chunks over Poland and potentially also over the Ukraine.

681
00:36:06.199 --> 00:36:09.559
Now I've not actually seen any reports showing debris on

682
00:36:09.559 --> 00:36:12.000
the ground in the Ukraine because obviously it's hard to

683
00:36:12.039 --> 00:36:14.440
get images out and given all the other problems they're

684
00:36:14.440 --> 00:36:16.519
facing at the minute. Although to be fair, this is

685
00:36:16.559 --> 00:36:19.159
the last thing that they need is additional bits of

686
00:36:19.199 --> 00:36:23.599
metal dropping on their country. But there are lots of

687
00:36:23.639 --> 00:36:26.719
bits that fell over Poland, including one bit that was

688
00:36:26.719 --> 00:36:28.760
found that is one and a half meters by one

689
00:36:28.840 --> 00:36:32.519
meter that damaged some lights and stuff around a warehouse.

690
00:36:33.360 --> 00:36:35.519
So this isn't just a bit of debris burning of

691
00:36:35.559 --> 00:36:38.199
palmusle in the atmosphere. This again is stuff making it

692
00:36:38.239 --> 00:36:41.320
to the ground intact, which is where people get worried.

693
00:36:41.360 --> 00:36:43.079
And it ties in quite nicely with some of the

694
00:36:43.079 --> 00:36:46.199
things that were being reported back with the Starship launch.

695
00:36:46.639 --> 00:36:49.440
Some statistics that was worked out based on the frequency

696
00:36:49.480 --> 00:36:52.119
things were coming back in twenty twenty three an hour

697
00:36:52.239 --> 00:36:54.960
use of airspace, saying that there was a twenty six

698
00:36:55.000 --> 00:36:57.599
per cent chance in any given year of a major

699
00:36:57.639 --> 00:37:01.400
space debrus re entry event over popular highly used air space.

700
00:37:01.440 --> 00:37:04.119
And that's exactly what this was. The report a few

701
00:37:04.199 --> 00:37:06.800
years ago that said the likelihood of somebody dying from

702
00:37:06.880 --> 00:37:08.760
space every in the next decade could be as high

703
00:37:08.760 --> 00:37:11.280
as one in ten. And this is the sobering reminder

704
00:37:11.320 --> 00:37:12.840
of that, because at the end of the day, for

705
00:37:12.880 --> 00:37:16.719
a bit of a SpaceX rocket, there's one meter buy

706
00:37:16.760 --> 00:37:19.360
one and a half meter lands on your head that's

707
00:37:19.400 --> 00:37:21.880
going to put a sizeable dent in your day. And

708
00:37:22.079 --> 00:37:25.880
there is fabulous footage about this, and I think the

709
00:37:25.920 --> 00:37:28.440
thing that offsets this is that SpaceX are trying to

710
00:37:28.480 --> 00:37:31.280
do things right. To give them the credit, they're bringing

711
00:37:31.320 --> 00:37:33.159
things back in as much as they can in a

712
00:37:33.159 --> 00:37:35.760
controlled fashion. We talked about this with a stylent sapllite

713
00:37:35.760 --> 00:37:38.360
the other week and on the whole they're trying to

714
00:37:38.400 --> 00:37:40.559
do that right now. There are other concerns, things like

715
00:37:40.599 --> 00:37:43.519
the pollution side of it. But this is a big

716
00:37:43.559 --> 00:37:47.960
reminder that space is difficult. Things go wrong and when

717
00:37:47.960 --> 00:37:50.760
we continue to put this many rockets up there, from

718
00:37:50.840 --> 00:37:52.559
time to time, some of them will come back in

719
00:37:52.679 --> 00:37:55.079
an uncontrolled fashion. And this is the second time, just

720
00:37:55.119 --> 00:37:58.800
in this calendar year, where significant trunks of debris have

721
00:37:58.840 --> 00:38:03.760
fallen over popular today space, bits of either lundered or

722
00:38:03.920 --> 00:38:07.079
washed up on pluss where people live. You know, somebod

723
00:38:07.119 --> 00:38:09.320
this car was damaged in one event, some of this

724
00:38:09.559 --> 00:38:13.079
warehouse damaged in another. It's not all planned selling. I

725
00:38:13.119 --> 00:38:14.760
guess it's a tack on from this. And there's a

726
00:38:14.800 --> 00:38:17.559
lot of fabulous coverage of it all over if you

727
00:38:17.639 --> 00:38:18.679
do a bit of browsing around.

728
00:38:19.000 --> 00:38:21.719
Oh yeah, And some of the pictures are incredible and

729
00:38:21.800 --> 00:38:27.639
the footage, this video footage and photographic material that shows

730
00:38:28.360 --> 00:38:31.280
and over a wide area, over a very wide area

731
00:38:31.320 --> 00:38:34.719
from England right through to Poland. These images have been

732
00:38:34.880 --> 00:38:38.159
published and yeah, I mean there's spectacular look at. But

733
00:38:38.239 --> 00:38:40.280
the fact that big chunks are hitting the ground and

734
00:38:40.320 --> 00:38:43.239
doing damage that is scary stuff. And read you and

735
00:38:43.280 --> 00:38:46.079
I have talked about in the past not only the

736
00:38:46.440 --> 00:38:50.079
threat or the potential threat to life as a consequence

737
00:38:50.079 --> 00:38:55.079
of this human being killed or injured under these circumstances,

738
00:38:55.119 --> 00:38:59.840
but also what the impact might be in the insurance

739
00:38:59.880 --> 00:39:04.800
industry because people may have to ensure against this kind

740
00:39:04.840 --> 00:39:05.079
of thing.

741
00:39:07.039 --> 00:39:10.000
Sorry, John Ty, we've got stalin age.

742
00:39:10.079 --> 00:39:10.360
Sorry.

743
00:39:10.400 --> 00:39:14.119
Starship as coming up this week, is that right? The

744
00:39:14.239 --> 00:39:16.639
launch of the next So.

745
00:39:16.639 --> 00:39:21.159
Yeah, that's come around quicker than anticipated, and it's because

746
00:39:21.239 --> 00:39:25.159
SpaceX are very transparent in their efforts to understand what

747
00:39:25.199 --> 00:39:28.000
went wrong, so they've been able to escalate the approvals

748
00:39:28.039 --> 00:39:31.639
through may or may not have anything also to do

749
00:39:31.760 --> 00:39:35.199
with the prominence of their owner at the minute and

750
00:39:35.320 --> 00:39:39.280
his strong connections. But yeah, I'm surprised that they're launching

751
00:39:39.320 --> 00:39:43.119
again so quickly after that went wrong. But they are

752
00:39:44.000 --> 00:39:47.760
very enthusiastic on testing things by destruction. They are quite

753
00:39:47.840 --> 00:39:50.679
rightly of the opinion that when things go wrong, that's

754
00:39:50.719 --> 00:39:52.159
when you learn the most, and that's when you can

755
00:39:52.280 --> 00:39:54.400
viccings and improve them. And they've done a fabulous job

756
00:39:54.440 --> 00:39:57.119
that's how their whole business model has worked all the

757
00:39:57.119 --> 00:39:59.960
way through. But it still feels a little bit too soon.

758
00:40:01.239 --> 00:40:05.079
Well, they're talking about the twenty eighth of February actually, yes,

759
00:40:05.639 --> 00:40:07.880
as the next mega rocket launch.

760
00:40:08.000 --> 00:40:10.639
So and most of these things are streamed live, of course,

761
00:40:10.679 --> 00:40:12.360
aren't they. So you will be able to watch along

762
00:40:12.400 --> 00:40:14.639
with that if you're interested in that kind of thing.

763
00:40:14.639 --> 00:40:17.079
And I think that's another really positive that's come out

764
00:40:17.079 --> 00:40:19.280
of this. When I was a kid, launchers were not

765
00:40:19.360 --> 00:40:21.880
as common, but you only ever heard about the month

766
00:40:21.880 --> 00:40:23.840
of news when something went wrong. And I remember as

767
00:40:23.880 --> 00:40:27.719
a kid challenger, I remember the other Shuttle disaster during

768
00:40:27.760 --> 00:40:30.800
my PhD, but other than that, you couldn't watch it.

769
00:40:30.800 --> 00:40:34.360
It's not like it was live and televised. And yet

770
00:40:34.400 --> 00:40:37.320
now you can tune in, you can watch these things

771
00:40:37.320 --> 00:40:41.760
as they happen, both NASSA launchers but SpaceX launchers. It's fabulous.

772
00:40:41.800 --> 00:40:43.079
It's a great time to be lying.

773
00:40:43.599 --> 00:40:46.079
Yeah, oh well, it's reach to point where people go

774
00:40:46.159 --> 00:40:49.440
to watch these things like they do go to watch

775
00:40:49.480 --> 00:40:51.960
Nest car races and you only go for the crash.

776
00:40:52.039 --> 00:40:57.760
So it's that's kind of where it's sort of and

777
00:40:59.079 --> 00:41:07.639
SpaceX hasn't appointed very they've had several successful failures, so yes,

778
00:41:07.639 --> 00:41:10.880
it's a bit of a scheduled disassemblies. Is that what

779
00:41:11.480 --> 00:41:12.840
you disassembly is another one?

780
00:41:12.920 --> 00:41:13.079
Yes.

781
00:41:13.639 --> 00:41:19.880
Anyway, Friday, apparently the Starship Bait launch is scheduled for

782
00:41:20.039 --> 00:41:21.840
so we'll see how that pans out.

783
00:41:21.920 --> 00:41:25.199
It'd be interesting to see if anybody flying to Johannesburg

784
00:41:25.280 --> 00:41:27.159
with Quantas gets de layed with that one, because that

785
00:41:27.239 --> 00:41:29.920
was another problem with the previous one, because they are

786
00:41:30.639 --> 00:41:32.679
where they look to bring in the upper stedge of

787
00:41:32.719 --> 00:41:35.760
Starship if it goes well, it's directly on the flight

788
00:41:35.800 --> 00:41:39.239
path from Sydney to Hammersburg, and so Quantus flights kept

789
00:41:39.280 --> 00:41:41.559
being delayed at short notice. When SpaceX said we're going

790
00:41:41.599 --> 00:41:43.280
to launch, actually no we're not. Oh no, we're going

791
00:41:43.320 --> 00:41:46.320
to launch now. No we're not, because you can't fly

792
00:41:46.400 --> 00:41:48.679
through the space where a rocket might hit your plane,

793
00:41:48.679 --> 00:41:50.400
even though the odds are vanishingly small,
