1
00:00:01,320 --> 00:00:08,080
Speaker 1: Five double A notes with Matthew Pantellis. Let's talk astronomy

2
00:00:08,280 --> 00:00:11,400
Speaker 1: and on the line, well probably Australia's number one astronomy

3
00:00:11,520 --> 00:00:14,880
Speaker 1: Dave Reddicky, Astro Space News. Hello Dave, how are you?

4
00:00:14,960 --> 00:00:18,160
Speaker 2: Oh? Blush blush plus?

5
00:00:18,200 --> 00:00:20,400
Speaker 1: Did you get a look at the aurora the other night?

6
00:00:21,480 --> 00:00:23,840
Speaker 2: I did. Yeah, we were up here in Port for

7
00:00:23,960 --> 00:00:26,120
Speaker 2: Corey on the mid north coast of your South Wales.

8
00:00:27,920 --> 00:00:31,280
Speaker 2: I've never seen it so bright really twenty years. In

9
00:00:31,360 --> 00:00:35,440
Speaker 2: twenty years of looking at this and seeing other people photographs,

10
00:00:35,880 --> 00:00:37,720
Speaker 2: this is probably the best I've seen. I mean, I

11
00:00:37,720 --> 00:00:40,479
Speaker 2: couldn't believe how strong that was. There's a pretty good

12
00:00:40,560 --> 00:00:42,519
Speaker 2: reason for it too. We've got hit by a massive

13
00:00:42,560 --> 00:00:43,360
Speaker 2: solar fla.

14
00:00:44,000 --> 00:00:46,800
Speaker 1: So how big in terms of you know, if we

15
00:00:46,920 --> 00:00:49,120
Speaker 1: rated them out of ten or whatever. This is right

16
00:00:49,159 --> 00:00:49,959
Speaker 1: up there obviously.

17
00:00:51,240 --> 00:00:54,320
Speaker 2: Are you sitting in your chair? Quiet down, Well, I'm

18
00:00:54,320 --> 00:00:57,120
Speaker 2: sitting on your chair. I'm going to tell you something

19
00:00:57,160 --> 00:01:00,840
Speaker 2: now that I'm not making up. This is a major

20
00:01:00,920 --> 00:01:04,920
Speaker 2: solar flared. Making a mistake about it, This is a

21
00:01:04,959 --> 00:01:08,800
Speaker 2: massive bomb going off. To put it into understandable terms,

22
00:01:09,120 --> 00:01:11,920
Speaker 2: the flare we had was equal to about one hundred

23
00:01:11,959 --> 00:01:15,640
Speaker 2: and sixty billion Hiroshima bombs. Wow, staying off at once

24
00:01:15,800 --> 00:01:18,119
Speaker 2: or say it again, one hundred and sixty. There's enough

25
00:01:18,440 --> 00:01:21,839
Speaker 2: energy there to run the entire city of Adelaide about

26
00:01:21,880 --> 00:01:26,000
Speaker 2: fifty thousand years. Goodness true, nothing made up here. There's

27
00:01:26,040 --> 00:01:28,840
Speaker 2: a massive amount of energy in that. Now a lot

28
00:01:28,880 --> 00:01:30,400
Speaker 2: of that you think, well, hang on, that's a lot

29
00:01:30,440 --> 00:01:32,960
Speaker 2: of power can destroy the earth. A lot of it

30
00:01:33,040 --> 00:01:35,800
Speaker 2: was radiated in this space as well. I'm just giving

31
00:01:35,840 --> 00:01:38,480
Speaker 2: you the amount of power in that particular flare, and

32
00:01:38,560 --> 00:01:41,720
Speaker 2: this is called an next class flare. They can still

33
00:01:41,760 --> 00:01:45,280
Speaker 2: equal millions of Hiroshima bombs, even if they're small. The

34
00:01:45,400 --> 00:01:48,200
Speaker 2: Sun's going through a cycle at the moment, very very active.

35
00:01:48,560 --> 00:01:50,840
Speaker 2: Every eleven years it becomes active and then every eleven

36
00:01:50,920 --> 00:01:53,760
Speaker 2: years becoming inactive. We don't know why, but there you go.

37
00:01:53,840 --> 00:01:55,240
Speaker 2: There's a lot of power up there. And you know

38
00:01:55,320 --> 00:01:59,840
Speaker 2: why I always advocate using solar energy. It's free.

39
00:02:00,200 --> 00:02:00,440
Speaker 3: Yeah.

40
00:02:00,480 --> 00:02:03,800
Speaker 1: Well that's right. Gee, that's amazing, isn't it. So if

41
00:02:03,800 --> 00:02:05,600
Speaker 1: you missed it, I suppose, Well, we don't know what

42
00:02:05,720 --> 00:02:07,560
Speaker 1: it's going to happen either, do we that I know

43
00:02:07,640 --> 00:02:10,040
Speaker 1: there were alerts put out earlier in the day that

44
00:02:10,080 --> 00:02:12,000
Speaker 1: we were in for it. But that's probably about as

45
00:02:12,080 --> 00:02:13,160
Speaker 1: much notice as we'd get.

46
00:02:13,880 --> 00:02:16,680
Speaker 2: Yeah, up until about fifteen years ago, we couldn't had

47
00:02:16,760 --> 00:02:19,280
Speaker 2: no way of determining what's going to happen. We can

48
00:02:19,320 --> 00:02:23,680
Speaker 2: now kind of predicted because we've got satellites now that

49
00:02:23,800 --> 00:02:26,920
Speaker 2: monitor both sides. Some before we can only see the

50
00:02:26,960 --> 00:02:28,760
Speaker 2: side that we're looking at. Did you know the Sun

51
00:02:28,880 --> 00:02:33,399
Speaker 2: rotates every twenty eight days, Oh, like the most it does.

52
00:02:33,440 --> 00:02:37,880
Speaker 2: It it spins around. Even though it's a ball of gas,

53
00:02:37,440 --> 00:02:41,280
Speaker 2: it does have a rotation period. Now, with that being

54
00:02:41,320 --> 00:02:44,360
Speaker 2: the case, we can see these sun spots appear, and

55
00:02:44,360 --> 00:02:46,320
Speaker 2: then when we see them appeer, we know there's going

56
00:02:46,360 --> 00:02:48,840
Speaker 2: to be a solo flare. The bigger of the sun spot,

57
00:02:49,200 --> 00:02:51,720
Speaker 2: the more massive the flare. So what astronomers are doing

58
00:02:51,760 --> 00:02:54,919
Speaker 2: now they've got the the SOHO and other satellites that

59
00:02:55,040 --> 00:02:58,240
Speaker 2: monitored the Sun from front, back, sides and everything. Now

60
00:02:58,240 --> 00:03:00,200
Speaker 2: we can see a flare on the other side. Out

61
00:03:00,200 --> 00:03:03,239
Speaker 2: of the three weeks before, it's two weeks before it

62
00:03:03,280 --> 00:03:06,880
Speaker 2: can actually come in point it towards us. So we

63
00:03:07,320 --> 00:03:09,519
Speaker 2: know straight away that there's a four warning there watch

64
00:03:09,560 --> 00:03:12,000
Speaker 2: out for this one, so we can be prepared for.

65
00:03:12,080 --> 00:03:15,760
Speaker 2: But this worries the moment. Now in modern day terms,

66
00:03:15,800 --> 00:03:19,960
Speaker 2: everything is shielded fairly will and the result we get

67
00:03:20,000 --> 00:03:23,079
Speaker 2: from that is fantastic, with those beautiful ribbons of light there.

68
00:03:23,560 --> 00:03:26,880
Speaker 2: When those flares happen, the energy hits the earth radio

69
00:03:27,000 --> 00:03:31,000
Speaker 2: say the Norse, it's out pole and because they're magnetic,

70
00:03:31,040 --> 00:03:34,240
Speaker 2: they interfere with the light. It changes the atmosphere, it

71
00:03:34,280 --> 00:03:36,960
Speaker 2: breaks it up into a different colored spectrum like you

72
00:03:37,040 --> 00:03:39,320
Speaker 2: see in a rainbow. And that's why we see those

73
00:03:39,320 --> 00:03:42,240
Speaker 2: beautiful ribbons of light there. There's nothing next to a

74
00:03:42,320 --> 00:03:45,200
Speaker 2: solar eclips that I've ever seen that equals and.

75
00:03:45,280 --> 00:03:49,920
Speaker 1: The beauty is wow. I missed it in here. And

76
00:03:50,000 --> 00:03:53,160
Speaker 1: when I drove home, which I don't have long to go,

77
00:03:53,760 --> 00:03:55,760
Speaker 1: you know, I think in the city it was hard

78
00:03:55,760 --> 00:03:57,320
Speaker 1: to see. You had to be out of the city,

79
00:03:57,360 --> 00:03:59,960
Speaker 1: you know. People set photos from the beach down here.

80
00:04:00,000 --> 00:04:02,760
Speaker 1: You're in Adelaide, and I could see it and up

81
00:04:02,800 --> 00:04:04,960
Speaker 1: in the hills, but not so much here in the city.

82
00:04:05,600 --> 00:04:07,840
Speaker 2: Well, so you're lucky, Dan, because you're a for your

83
00:04:07,880 --> 00:04:11,480
Speaker 2: down south and the further south you are a better

84
00:04:11,560 --> 00:04:16,960
Speaker 2: Victorian and Hober I mean this is look. I wish

85
00:04:17,000 --> 00:04:20,320
Speaker 2: I could have been down there, but the further absolutely

86
00:04:20,560 --> 00:04:23,640
Speaker 2: people who see these, A lot of people get jewvy.

87
00:04:24,560 --> 00:04:24,760
Speaker 1: You know.

88
00:04:25,120 --> 00:04:27,520
Speaker 2: It really brings out the emotions in people because it's

89
00:04:27,520 --> 00:04:30,960
Speaker 2: so beautiful. That's why I love what I do, because

90
00:04:31,120 --> 00:04:33,359
Speaker 2: it takes you away from the right base and the

91
00:04:33,400 --> 00:04:36,000
Speaker 2: mess we're in the plan. You know.

92
00:04:36,240 --> 00:04:39,320
Speaker 1: Yeah, Brett's called him with a comment about the soul

93
00:04:39,360 --> 00:04:40,360
Speaker 1: of Flairs. Could I Brett?

94
00:04:41,640 --> 00:04:46,600
Speaker 4: OHI Matt, I was just gonna and I live in

95
00:04:46,640 --> 00:04:49,560
Speaker 4: a township called Birdwood and it's in the Adelaide Hills,

96
00:04:49,560 --> 00:04:53,799
Speaker 4: so it's just out the data softwares. It was actually cloudy,

97
00:04:53,880 --> 00:04:57,159
Speaker 4: so we didn't speak too much. But the question that

98
00:04:57,240 --> 00:05:00,880
Speaker 4: I have is since the solar flares, I've had really

99
00:05:00,920 --> 00:05:04,880
Speaker 4: bad TV respection. I used to have a bad on SBS,

100
00:05:04,920 --> 00:05:08,000
Speaker 4: but now it's Channel seven and Channel nine. I wonder

101
00:05:08,040 --> 00:05:10,080
Speaker 4: if these massive squares had anything to do with it.

102
00:05:10,600 --> 00:05:16,400
Speaker 1: Well, you're missing the Golden Bachelor. What a shame, damn.

103
00:05:16,600 --> 00:05:19,360
Speaker 2: But can I tell you I've got a telescope here

104
00:05:19,360 --> 00:05:22,760
Speaker 2: called Sea Star, and I was watching television about half

105
00:05:22,800 --> 00:05:26,000
Speaker 2: an hour ago and it all went paywhile whacking all

106
00:05:26,000 --> 00:05:28,880
Speaker 2: over the place. So I've grabbed the tollscop going outside

107
00:05:29,279 --> 00:05:32,159
Speaker 2: private as you're ringing up there, we've got the same look.

108
00:05:32,200 --> 00:05:35,599
Speaker 2: I say to you, I don't think so it's not

109
00:05:35,720 --> 00:05:38,719
Speaker 2: that kind of interference. But it's not. It's not the

110
00:05:38,760 --> 00:05:41,880
Speaker 2: sort of interference that can really ruin TV reception as

111
00:05:41,920 --> 00:05:43,839
Speaker 2: far as I know, I'm not a technician, so I'm

112
00:05:43,839 --> 00:05:47,200
Speaker 2: only guessing here, but I'd say there was another reason

113
00:05:47,320 --> 00:05:51,760
Speaker 2: for that, coincidental as it may be, but the aurora

114
00:05:51,880 --> 00:05:57,000
Speaker 2: has it's it's not the top of electrical storm. It's

115
00:05:57,080 --> 00:05:59,080
Speaker 2: high up in the atmosphere. If you can understand what

116
00:05:59,120 --> 00:06:01,479
Speaker 2: I'm in. I think it's a way above the TV

117
00:06:01,600 --> 00:06:05,320
Speaker 2: and radio WAVELEK somebody out there with the technology that

118
00:06:05,440 --> 00:06:07,320
Speaker 2: might be helping with this one. But I don't think

119
00:06:07,400 --> 00:06:09,800
Speaker 2: breath that would have been the reason. But go and

120
00:06:09,839 --> 00:06:11,400
Speaker 2: find a TV, go to have a little bit.

121
00:06:13,279 --> 00:06:15,160
Speaker 1: Okay, thank you, good on your Brett. Thanks for the

122
00:06:15,200 --> 00:06:19,000
Speaker 1: great question, Because Dave, haven't these things knocked out or

123
00:06:19,040 --> 00:06:21,000
Speaker 1: the worry might be that they will in the future

124
00:06:21,040 --> 00:06:23,839
Speaker 1: knocked out telecommunication satellites and other things?

125
00:06:24,480 --> 00:06:27,839
Speaker 2: Yes, and no, good good question math here, And a

126
00:06:27,880 --> 00:06:30,560
Speaker 2: good answer to this one is simply, we've shielded our

127
00:06:30,600 --> 00:06:33,760
Speaker 2: stuff pretty well now. Up and in the nineteen fifties

128
00:06:33,760 --> 00:06:36,520
Speaker 2: and nineteen sixties, it was pretty bad. I mean there

129
00:06:36,520 --> 00:06:40,200
Speaker 2: were power stations that good would cause blackouts in power

130
00:06:40,200 --> 00:06:45,240
Speaker 2: strations because it infused the power. It was cause all

131
00:06:45,320 --> 00:06:49,480
Speaker 2: sorts of gramas. These things are not the short wave radio,

132
00:06:49,720 --> 00:06:52,480
Speaker 2: and people using those in those days couldn't really do much.

133
00:06:52,920 --> 00:06:55,120
Speaker 2: And yet hear radio. You'd hear crackle all the time

134
00:06:55,160 --> 00:06:59,640
Speaker 2: and l am radio. But since the intervention of FM

135
00:06:59,680 --> 00:07:03,200
Speaker 2: and with the technical capabilities we've got with you guys

136
00:07:03,240 --> 00:07:05,760
Speaker 2: with the big powerful radio station now around the world,

137
00:07:06,080 --> 00:07:08,920
Speaker 2: that's all shielding, so we don't get that. But I'll

138
00:07:08,920 --> 00:07:13,920
Speaker 2: go back to eighteen eighteen seventies around called the Carrington effect.

139
00:07:14,080 --> 00:07:19,520
Speaker 2: Want to look at up Carrington, Cawri and GTN. Something

140
00:07:19,600 --> 00:07:21,680
Speaker 2: happened then. We had a massive flare like this in

141
00:07:21,720 --> 00:07:24,680
Speaker 2: those years, and of course we didn't have TV or

142
00:07:24,720 --> 00:07:28,560
Speaker 2: telephones in that time. We had Morse code. What was

143
00:07:28,600 --> 00:07:31,520
Speaker 2: happening was that around the world, mainly in North America,

144
00:07:32,240 --> 00:07:34,760
Speaker 2: the operators of the Morse Code sets, we're getting electrical

145
00:07:34,840 --> 00:07:38,840
Speaker 2: shops through their equipment. Because this flare was so powerful

146
00:07:39,360 --> 00:07:42,400
Speaker 2: that it hadn't happened in the fifties and sixties, we

147
00:07:42,480 --> 00:07:45,280
Speaker 2: have knocked everything out of commission. Now in more modern

148
00:07:45,320 --> 00:07:48,800
Speaker 2: times after they had of satellites. Yes, they used to

149
00:07:48,840 --> 00:07:51,080
Speaker 2: have trouble with those a lot. And the ones who

150
00:07:51,080 --> 00:07:54,800
Speaker 2: are having trouble with the geo positioning satellites for people

151
00:07:54,840 --> 00:07:57,600
Speaker 2: who use those for airline companies for instance, you know,

152
00:07:57,720 --> 00:08:01,240
Speaker 2: for navigation. But most of us been shielded. Now we

153
00:08:01,320 --> 00:08:03,600
Speaker 2: don't really soon to have that much trouble. But boy,

154
00:08:04,200 --> 00:08:06,119
Speaker 2: you know there's a lot of power in these things

155
00:08:06,120 --> 00:08:08,840
Speaker 2: that there's more power in this something. Wouldn't we realize

156
00:08:08,960 --> 00:08:10,600
Speaker 2: absolutely should harness the more.

157
00:08:11,200 --> 00:08:13,680
Speaker 1: Yeah, we should. Hey what would it mean for astronauts

158
00:08:13,680 --> 00:08:14,559
Speaker 1: on the space station?

159
00:08:15,960 --> 00:08:19,120
Speaker 2: They've got to go inside a special room. Okay, yeah, yeah,

160
00:08:19,120 --> 00:08:21,160
Speaker 2: that's a good point. There's a safety room up there.

161
00:08:21,160 --> 00:08:24,240
Speaker 2: A lot of people know about. It's there for two reasons.

162
00:08:24,240 --> 00:08:27,360
Speaker 2: One of the radiation factors from what you're talking about now,

163
00:08:27,560 --> 00:08:31,000
Speaker 2: is they are outside the US atmosphere and they're more

164
00:08:31,240 --> 00:08:33,920
Speaker 2: they're more prone to copying doses of radiation there. But

165
00:08:33,960 --> 00:08:36,200
Speaker 2: all they're going to get in there in those in

166
00:08:36,240 --> 00:08:38,760
Speaker 2: those safe rooms is about one or two chest extra

167
00:08:40,240 --> 00:08:41,400
Speaker 2: they do have to go in.

168
00:08:41,320 --> 00:08:45,280
Speaker 1: There, and it's a safe room save for a home invasion

169
00:08:45,280 --> 00:08:50,720
Speaker 1: as well. Obviously up there Hueiye port Adelaide. Hello, Huey

170
00:08:51,480 --> 00:08:54,520
Speaker 1: came back to you and David, how are you?

171
00:08:54,720 --> 00:08:59,439
Speaker 2: I don't know why I've missed you up the season.

172
00:09:00,960 --> 00:09:03,080
Speaker 3: Listen, I've been one for a while. But we spoke

173
00:09:03,200 --> 00:09:12,880
Speaker 3: some months ago about the development of missiles to deter comets, asteroids,

174
00:09:13,000 --> 00:09:15,760
Speaker 3: meteorites that might be rode out for the bombing, I

175
00:09:15,760 --> 00:09:19,920
Speaker 3: mean close to the Earth from time to time. Who's

176
00:09:19,960 --> 00:09:23,640
Speaker 3: developed is there is a group between countries developing the

177
00:09:23,840 --> 00:09:29,720
Speaker 3: anti deflection missiles which are normal normally nuclear tipped, or

178
00:09:30,240 --> 00:09:32,480
Speaker 3: is it just America with something going alone or NASSA.

179
00:09:32,600 --> 00:09:34,920
Speaker 3: But who's developing it? And how far are we you

180
00:09:34,960 --> 00:09:37,240
Speaker 3: advance to be ready for the future.

181
00:09:38,400 --> 00:09:41,200
Speaker 2: The more the more run you get ahead of these things,

182
00:09:41,240 --> 00:09:46,080
Speaker 2: the better. If we had the doomsday scenario where there's

183
00:09:46,080 --> 00:09:48,920
Speaker 2: a massive rock coming our way, the whole point of

184
00:09:48,960 --> 00:09:51,840
Speaker 2: the exercise is we need time now because of a

185
00:09:51,880 --> 00:09:55,000
Speaker 2: mission called Doug D A T. If you want to

186
00:09:55,000 --> 00:09:57,960
Speaker 2: look that up. It's an asteroid deflection mission mission. Some

187
00:09:58,120 --> 00:10:01,360
Speaker 2: years ago NASA actually did a dry run on an

188
00:10:01,360 --> 00:10:05,240
Speaker 2: asteroid out there. They send us there, yeah, to ram

189
00:10:05,280 --> 00:10:07,559
Speaker 2: into it. They did move it a little bit, so

190
00:10:07,840 --> 00:10:10,360
Speaker 2: we know now how much energy it takes to move

191
00:10:10,400 --> 00:10:13,240
Speaker 2: a size piece of rock. Now, the thing you've got

192
00:10:13,280 --> 00:10:16,040
Speaker 2: to remember, there's no nuclear warhead on this stuff. You

193
00:10:16,040 --> 00:10:18,000
Speaker 2: don't do that. I think you don't do it. Blow

194
00:10:18,080 --> 00:10:21,959
Speaker 2: these up, you don't send Bruce Wilson has grew up there.

195
00:10:22,040 --> 00:10:25,439
Speaker 2: It's one thing we've got a nudge about of the

196
00:10:25,480 --> 00:10:28,280
Speaker 2: way and Hue why we say that if it's ten

197
00:10:28,400 --> 00:10:31,520
Speaker 2: years away or five years away, if we move it

198
00:10:31,559 --> 00:10:34,800
Speaker 2: only a slight amount in that time, that that'll become

199
00:10:34,840 --> 00:10:37,440
Speaker 2: a pretty wide margin. By something is in our direction,

200
00:10:37,559 --> 00:10:40,720
Speaker 2: it will bypasss. So we are now the first generation

201
00:10:40,880 --> 00:10:43,679
Speaker 2: in history to be able to survive anything that may

202
00:10:43,679 --> 00:10:49,640
Speaker 2: have previously wiped out human society. But there's setting our way.

203
00:10:49,640 --> 00:10:54,040
Speaker 2: There's nothing out there at the moment, sleep sleep, welterize

204
00:10:54,040 --> 00:10:58,360
Speaker 2: there's nothing out there. And ready we do have a

205
00:10:58,400 --> 00:11:00,600
Speaker 2: defense here. There is a defense mechan and for that

206
00:11:01,040 --> 00:11:02,839
Speaker 2: we know how to do that. Now, if we have

207
00:11:02,920 --> 00:11:05,680
Speaker 2: the lead up time and there's something out there, we

208
00:11:05,720 --> 00:11:07,599
Speaker 2: can we can move it quite easily. I think you

209
00:11:07,640 --> 00:11:09,400
Speaker 2: don't do us blow them up. If you do that,

210
00:11:09,440 --> 00:11:11,760
Speaker 2: you're going to get hit by hundreds of them. It

211
00:11:11,920 --> 00:11:16,000
Speaker 2: doesn't look bigger bits here yeah, cheers for that.

212
00:11:16,040 --> 00:11:18,440
Speaker 1: Good on you, Huie, thank you. And what is a

213
00:11:18,480 --> 00:11:21,360
Speaker 1: good lead up? Because sometimes Dave, as I've read, they

214
00:11:21,400 --> 00:11:23,760
Speaker 1: come from behind the sun. We don't see them until

215
00:11:23,800 --> 00:11:25,600
Speaker 1: it's you know, they're almost on us.

216
00:11:27,080 --> 00:11:28,760
Speaker 2: That's going to be a tricky one. You don't have

217
00:11:28,880 --> 00:11:32,040
Speaker 2: much time on that one either. But by the time

218
00:11:32,120 --> 00:11:34,560
Speaker 2: we have something coming our way, it's going to go

219
00:11:34,679 --> 00:11:37,880
Speaker 2: before the Sun because they come from the asteroid built

220
00:11:37,920 --> 00:11:40,520
Speaker 2: so they've got to go past mass and they've got

221
00:11:40,520 --> 00:11:43,160
Speaker 2: to go through past Earth then to the Sun. It

222
00:11:43,200 --> 00:11:45,240
Speaker 2: doesn't work the other way around. If it went around

223
00:11:45,280 --> 00:11:48,720
Speaker 2: the Sun and swung back getting towards us, well we'd

224
00:11:48,800 --> 00:11:49,640
Speaker 2: have we'd.

225
00:11:49,480 --> 00:11:52,959
Speaker 1: Have a few months, I think, and by then we

226
00:11:53,120 --> 00:11:56,280
Speaker 1: know it's trajectory anyway, and you know there's an intersecting point.

227
00:11:56,360 --> 00:11:59,959
Speaker 1: It's so interesting. I mean, the calculations involved in this

228
00:12:00,080 --> 00:12:02,560
Speaker 1: where where in space will the Earth be in six

229
00:12:02,640 --> 00:12:06,360
Speaker 1: months time? And this little beck hit us unreal.

230
00:12:07,160 --> 00:12:12,000
Speaker 2: Can you imagine you have to send the spacecraft out months? Yeah,

231
00:12:12,080 --> 00:12:17,640
Speaker 2: months ahead of time yep, and just my power on

232
00:12:17,720 --> 00:12:20,640
Speaker 2: the phone. You've got to send it out months ahead

233
00:12:20,679 --> 00:12:22,520
Speaker 2: of time. You've got to be at a certain point

234
00:12:22,960 --> 00:12:25,360
Speaker 2: and within a micro second. I took a second. A

235
00:12:25,440 --> 00:12:28,320
Speaker 2: micro second of that happened because these season are living

236
00:12:28,400 --> 00:12:31,120
Speaker 2: so quickly that even a fraction of a second could

237
00:12:31,160 --> 00:12:35,200
Speaker 2: mean couple one hundred meters unreality is fantastic.

238
00:12:35,280 --> 00:12:38,280
Speaker 1: How about that? Hey, just before you leave us, So

239
00:12:38,440 --> 00:12:42,560
Speaker 1: I understand there's a damaged capsule up in space at

240
00:12:42,559 --> 00:12:45,960
Speaker 1: the moment, and it's the Chinese one with three astronauts

241
00:12:46,040 --> 00:12:46,480
Speaker 1: on board.

242
00:12:47,360 --> 00:12:51,040
Speaker 2: Yeah, they've come back. Yeah, I've just brought them back here.

243
00:12:51,200 --> 00:12:54,680
Speaker 2: Apparently piece of space junk clouded space left up there,

244
00:12:55,520 --> 00:12:57,719
Speaker 2: and and it did put them out of action for

245
00:12:57,720 --> 00:12:59,480
Speaker 2: a while. I don't know what the Chinese don't then

246
00:12:59,559 --> 00:13:02,439
Speaker 2: we tell us up much about what they do or

247
00:13:02,440 --> 00:13:05,439
Speaker 2: how they fix thing that they did get them back again.

248
00:13:05,960 --> 00:13:08,559
Speaker 2: So there was three guys up there from two or

249
00:13:08,600 --> 00:13:12,240
Speaker 2: three days, sort of body their collective mails. Wow, but

250
00:13:13,600 --> 00:13:16,000
Speaker 2: it is a problem. I did space junk up there.

251
00:13:16,120 --> 00:13:19,320
Speaker 2: It's to keep the space station. Quite often more than

252
00:13:19,360 --> 00:13:21,440
Speaker 2: what you realize, they're going to move that space station

253
00:13:21,559 --> 00:13:23,959
Speaker 2: two or three times every year to get out of

254
00:13:23,960 --> 00:13:27,600
Speaker 2: the way of space drunks bloating by. Not much we

255
00:13:27,640 --> 00:13:30,360
Speaker 2: can do about it. We've got that we've made that problem,

256
00:13:31,640 --> 00:13:34,240
Speaker 2: and if we leave it for thirty years, we don't

257
00:13:34,240 --> 00:13:37,480
Speaker 2: do anymore. They'll probably all clean up. But at the moment,

258
00:13:37,559 --> 00:13:40,360
Speaker 2: you know, there's more satellites going up every day in

259
00:13:40,440 --> 00:13:42,320
Speaker 2: on muster smalls another twenty or thirty.

260
00:13:42,400 --> 00:13:46,679
Speaker 1: Oh well, okay, lovely, yeah, and what's that doing for

261
00:13:47,000 --> 00:13:48,880
Speaker 1: people like you? Trying to look up in space? All

262
00:13:48,920 --> 00:13:50,280
Speaker 1: you'd see is satellites.

263
00:13:51,080 --> 00:13:53,920
Speaker 2: Oh, it doesn't affect us. We're just amateur astronomers. But

264
00:13:53,960 --> 00:13:56,400
Speaker 2: the big observatories really come. They're out of action now,

265
00:13:57,000 --> 00:14:00,720
Speaker 2: a lot of observice closing down during the ofation work.

266
00:14:01,040 --> 00:14:03,559
Speaker 2: What they were doing. And the reason I say that

267
00:14:03,640 --> 00:14:07,080
Speaker 2: what observatories do now, you don't look through telescopes. You

268
00:14:07,120 --> 00:14:10,240
Speaker 2: sit in the control room, nice air condition room there,

269
00:14:10,240 --> 00:14:13,439
Speaker 2: and you work with computer screens and they're all automated.

270
00:14:13,760 --> 00:14:17,040
Speaker 2: But with the satellites up there and taking photographs with

271
00:14:17,080 --> 00:14:19,880
Speaker 2: the high powered telescopes. They've got the observatories around the

272
00:14:19,880 --> 00:14:23,680
Speaker 2: world and high up on mountains their time exposures, Matthew,

273
00:14:23,760 --> 00:14:26,560
Speaker 2: and you can't really be looking at a nebula or

274
00:14:26,560 --> 00:14:29,560
Speaker 2: a cluster or something out for here, looking propuls ten

275
00:14:29,640 --> 00:14:31,760
Speaker 2: billion light years away and then all of a sudden,

276
00:14:31,760 --> 00:14:34,040
Speaker 2: the streak of light shoes by. You don't know what

277
00:14:34,160 --> 00:14:37,200
Speaker 2: it is, an asteroid or comet or what. So they

278
00:14:37,240 --> 00:14:41,360
Speaker 2: do it afere with the results. That's why astronomers are

279
00:14:41,360 --> 00:14:44,640
Speaker 2: getting pretty peeed off, you know, Belion Musk and others

280
00:14:44,720 --> 00:14:47,160
Speaker 2: like that. It'll all change when we go to the Moon.

281
00:14:47,240 --> 00:14:49,560
Speaker 2: We put telescopes on the Moon back together.

282
00:14:49,880 --> 00:14:51,160
Speaker 1: Absolutely, that'll be interesting.

283
00:14:51,160 --> 00:14:54,400
Speaker 2: There's an issue with them, though they've told Musk about it.

284
00:14:54,440 --> 00:14:55,000
Speaker 2: They're not happy.

285
00:14:55,200 --> 00:14:58,200
Speaker 1: No, I'm sure. Hey, I don't know if you're across this,

286
00:14:58,320 --> 00:15:03,320
Speaker 1: but here in our data sky, the internationally declared Dark

287
00:15:03,360 --> 00:15:06,280
Speaker 1: Sky Reserve, we've got around the river Murray taking in

288
00:15:06,600 --> 00:15:10,040
Speaker 1: a town called swan Reach, which is sort of up

289
00:15:10,160 --> 00:15:13,280
Speaker 1: upstream from where you were what about a year or

290
00:15:13,320 --> 00:15:18,400
Speaker 1: so ago, six months ago at Vale you went to

291
00:15:18,480 --> 00:15:21,240
Speaker 1: murray Bridge and this is just yeah, just up the

292
00:15:21,320 --> 00:15:23,680
Speaker 1: river pass Morgan and a little bit on and you

293
00:15:23,720 --> 00:15:29,080
Speaker 1: get the Swan Reach and an observatory has just opened there. Yeah,

294
00:15:29,080 --> 00:15:32,320
Speaker 1: in the Dark Sky Region and or reserve. And it's

295
00:15:32,360 --> 00:15:37,720
Speaker 1: only a handful of observatories and big telescope. It's the

296
00:15:38,200 --> 00:15:42,280
Speaker 1: plane wave c DK seven hundred, which means nothing to me,

297
00:15:42,360 --> 00:15:44,920
Speaker 1: but it might to you. It's a world class research

298
00:15:45,000 --> 00:15:48,480
Speaker 1: grade telescope and people can go up and have a look,

299
00:15:48,520 --> 00:15:49,800
Speaker 1: which is pretty.

300
00:15:49,520 --> 00:15:53,720
Speaker 2: Com go down and do it here. They probably had regnized. Yeah,

301
00:15:53,760 --> 00:15:55,840
Speaker 2: this is good to hear. I'm never in a dark

302
00:15:55,840 --> 00:15:58,600
Speaker 2: sky area. That's why they're taking about it. For you've

303
00:15:58,600 --> 00:16:01,040
Speaker 2: got some beautiful sides down Adelaide there there should be

304
00:16:02,160 --> 00:16:05,080
Speaker 2: use more effectively. But this is a great more about that.

305
00:16:06,080 --> 00:16:10,840
Speaker 1: You can google it one reach observatory and you'll find it. Yeah,

306
00:16:10,880 --> 00:16:13,800
Speaker 1: that's good, beautiful, Good on your Dave. Thank you for

307
00:16:13,840 --> 00:16:16,320
Speaker 1: your time as always and taking those calls, and we'll
