00:00:00.560 --> 00:00:02.800
Anna: Good day and welcome to Astronomy

1
00:00:02.800 --> 00:00:04.320
AstroDailyPod. I'm Anna.

2
00:00:04.400 --> 00:00:07.040
Avery: And I'm Avery. And if you only listen to us

3
00:00:07.040 --> 00:00:08.760
once this year, make it the next

4
00:00:08.760 --> 00:00:11.480
Anna: two days, because tomorrow, the 12th of

5
00:00:11.480 --> 00:00:14.080
August, the moon does something it hasn't

6
00:00:14.080 --> 00:00:16.000
done over mainland Europe since

7
00:00:16.079 --> 00:00:18.320
1999. It slides

8
00:00:18.400 --> 00:00:21.320
completely in front of the sun, the one and

9
00:00:21.320 --> 00:00:23.520
only total solar eclipse of

10
00:00:23.520 --> 00:00:24.560
2026.

11
00:00:24.960 --> 00:00:27.640
Avery: And then, once the sun goes down, the same

12
00:00:27.640 --> 00:00:29.520
new Moon that made that eclipse possible

13
00:00:29.760 --> 00:00:32.500
steps out of the way entirely. Hands us the

14
00:00:32.500 --> 00:00:35.060
darkest Perseid meteor peak in about 20

15
00:00:35.060 --> 00:00:35.420
years.

16
00:00:35.980 --> 00:00:38.540
Anna: One new moon, two headline events

17
00:00:38.620 --> 00:00:41.540
roughly 24 hours apart. We'll set the

18
00:00:41.540 --> 00:00:44.020
whole thing up for you. Northern and southern

19
00:00:44.020 --> 00:00:45.860
skies both, Plus a

20
00:00:45.860 --> 00:00:48.110
Avery: rough morning for one Chinese rocket, a, uh,

21
00:00:48.179 --> 00:00:50.140
quieter question mark hanging over another,

22
00:00:50.380 --> 00:00:52.820
and Japan quietly finishing off its own

23
00:00:52.820 --> 00:00:54.940
answer to gps. Let's get into it.

24
00:00:55.260 --> 00:00:57.980
Anna: So let's talk about tomorrow properly,

25
00:00:58.220 --> 00:01:00.970
because this is a genuinely rare one. Uh, a

26
00:01:00.970 --> 00:01:03.650
total solar eclipse happens somewhere on

27
00:01:03.650 --> 00:01:06.650
Earth roughly 18 months or so. But the

28
00:01:06.650 --> 00:01:09.530
last time totality touched down anywhere on

29
00:01:09.530 --> 00:01:12.410
the planet was April 2024 over

30
00:01:12.410 --> 00:01:15.130
North America. That's more than two years

31
00:01:15.130 --> 00:01:17.650
ago. Tomorrow ends that drought,

32
00:01:18.050 --> 00:01:20.610
and the geography of this one is strange and

33
00:01:20.610 --> 00:01:23.370
beautiful. Most total eclipses

34
00:01:23.370 --> 00:01:26.330
race roughly west to east across the middle

35
00:01:26.330 --> 00:01:29.330
of the globe. This one goes over the top of

36
00:01:29.330 --> 00:01:32.210
the world. The Moon's shadow first touches

37
00:01:32.210 --> 00:01:34.970
down in the far north of Siberia, then

38
00:01:35.050 --> 00:01:37.850
arcs up and over the North Pole, drops

39
00:01:37.850 --> 00:01:40.730
down onto eastern Greenland, crosses the west

40
00:01:40.730 --> 00:01:43.369
coast of Iceland, including Reykjavik,

41
00:01:43.530 --> 00:01:46.530
and finishes across northern Spain and just

42
00:01:46.530 --> 00:01:49.210
clips the northwestern corner of Portugal.

43
00:01:49.530 --> 00:01:52.330
Totality itself is brief. At most

44
00:01:52.330 --> 00:01:55.250
about 2 minutes and 18 seconds right on

45
00:01:55.250 --> 00:01:57.790
the centre line. Blink and you miss it by

46
00:01:57.790 --> 00:02:00.630
eclipse standards. But the setting more than

47
00:02:00.630 --> 00:02:03.430
makes up for it, because in Spain, the sun

48
00:02:03.430 --> 00:02:06.150
is hanging low in the west, close to the

49
00:02:06.150 --> 00:02:09.030
horizon. In the last light before sunset,

50
00:02:09.350 --> 00:02:12.309
imagine the sun's corona flaring out over

51
00:02:12.309 --> 00:02:15.190
a Spanish skyline at dusk. That's

52
00:02:15.190 --> 00:02:17.390
the image people have been planning trips

53
00:02:17.390 --> 00:02:20.310
around for years now before anyone

54
00:02:20.310 --> 00:02:22.430
in the Southern Hemisphere gets their hopes

55
00:02:22.430 --> 00:02:24.950
up. Let me be straight with you, because we

56
00:02:24.950 --> 00:02:27.670
always are on this show. This eclipse is a

57
00:02:27.670 --> 00:02:30.070
Northern Hemisphere event full stop.

58
00:02:30.390 --> 00:02:32.790
Totality is only over Greenland,

59
00:02:32.870 --> 00:02:35.630
Iceland, northern Spain and that little bit

60
00:02:35.630 --> 00:02:38.590
of Portugal. A much wider slice of the world

61
00:02:38.590 --> 00:02:40.830
gets a partial eclipse. Parts of North

62
00:02:40.830 --> 00:02:43.670
America, especially eastern Canada and

63
00:02:43.670 --> 00:02:46.190
the northeastern United States, will see the

64
00:02:46.190 --> 00:02:49.190
sun take a bite low in the sky near sunset.

65
00:02:49.350 --> 00:02:52.190
But here in Australia, we see nothing at

66
00:02:52.190 --> 00:02:54.950
all. So southern listeners, stay with us.

67
00:02:55.110 --> 00:02:57.550
Your night is coming later in the show, and

68
00:02:57.550 --> 00:02:58.470
it's a good one.

69
00:02:58.790 --> 00:03:01.670
Here's the scale that gets me though, add up

70
00:03:01.670 --> 00:03:04.470
everyone who falls under at least a partial

71
00:03:04.470 --> 00:03:07.270
shadow tomorrow across Europe, North Africa,

72
00:03:07.510 --> 00:03:10.230
northern Asia and much of North America.

73
00:03:10.310 --> 00:03:12.390
And you're talking on the order of, um, a

74
00:03:12.390 --> 00:03:15.110
billion people who can in principle

75
00:03:15.350 --> 00:03:18.310
look up and see the moon and sun overlap.

76
00:03:18.830 --> 00:03:21.710
One event, a billion potential witnesses.

77
00:03:21.950 --> 00:03:24.670
And it's not just a spectacle, it's a working

78
00:03:24.670 --> 00:03:27.350
day for scientists. Those couple of minutes

79
00:03:27.350 --> 00:03:30.070
of totality are one of the only times we can

80
00:03:30.070 --> 00:03:32.990
study the sun's corona, that faint outer

81
00:03:32.990 --> 00:03:35.230
atmosphere directly from the ground.

82
00:03:35.710 --> 00:03:38.310
Space agencies and observatories along the

83
00:03:38.310 --> 00:03:40.950
track are gearing up. The European Space

84
00:03:40.950 --> 00:03:43.470
Agency, for instance, is running a live

85
00:03:43.470 --> 00:03:46.030
broadcast from the Havalambra Observatory in

86
00:03:46.030 --> 00:03:48.820
Spain, stitching together telescope feeds and

87
00:03:48.820 --> 00:03:51.260
drone footage so that even if you're nowhere

88
00:03:51.260 --> 00:03:54.060
near the path, you can watch totality as it

89
00:03:54.060 --> 00:03:56.740
happens. The ever reality is the

90
00:03:56.740 --> 00:03:59.100
weather, of course. It always is with

91
00:03:59.100 --> 00:04:02.020
eclipses. Greenland is remote and cold,

92
00:04:02.100 --> 00:04:04.660
but the air coming off the ice sheet actually

93
00:04:04.660 --> 00:04:07.540
tends to clear the skies, so the odds there

94
00:04:07.540 --> 00:04:10.540
aren't bad. Iceland is Iceland. It

95
00:04:10.540 --> 00:04:12.900
could be crystal clear or socked in with

96
00:04:12.900 --> 00:04:15.320
cloud, sometimes within the same hour.

97
00:04:15.640 --> 00:04:18.320
And Spain has the best of both worlds for

98
00:04:18.320 --> 00:04:21.320
most travellers. Reliable late summer skies

99
00:04:21.480 --> 00:04:24.360
and the roads, airports and towns to actually

100
00:04:24.440 --> 00:04:27.440
get people into the path. That's why the bulk

101
00:04:27.440 --> 00:04:30.000
of eclipse chasers are converging on Spain

102
00:04:30.000 --> 00:04:32.960
and Iceland tonight, watching forecasts

103
00:04:32.960 --> 00:04:35.680
like hawks. We'll give you the exact viewing

104
00:04:35.680 --> 00:04:38.440
times for the path and for North America, um,

105
00:04:38.440 --> 00:04:41.170
in the sky watch at the end. For now, the

106
00:04:41.170 --> 00:04:44.010
headline is simply, After 27

107
00:04:44.010 --> 00:04:46.850
years, totality is coming home to Europe.

108
00:04:47.170 --> 00:04:49.250
And whatever the sky is doing where you are

109
00:04:49.250 --> 00:04:52.130
tomorrow. It is worth a look, it really

110
00:04:52.130 --> 00:04:52.450
is.

111
00:04:52.930 --> 00:04:55.410
Avery: And from something rising to something that

112
00:04:55.410 --> 00:04:56.530
came down the hard way.

113
00:04:57.010 --> 00:04:59.650
So yesterday was by any measure an

114
00:04:59.650 --> 00:05:02.530
extraordinary day for launches. Four flights

115
00:05:02.530 --> 00:05:05.490
across three countries inside about 12 hours.

116
00:05:06.210 --> 00:05:08.450
And China opened it with a hard one to watch

117
00:05:08.930 --> 00:05:11.810
along March 7 a. That's a state rocket

118
00:05:11.810 --> 00:05:14.130
from the big state contractor cask,

119
00:05:14.370 --> 00:05:16.690
lifted off from the Wenchang launch site on

120
00:05:16.690 --> 00:05:19.690
the island of Hainan. And about 85 seconds

121
00:05:19.690 --> 00:05:22.009
into the flight, still climbing, still on

122
00:05:22.009 --> 00:05:24.690
that first main burn, it exploded.

123
00:05:24.930 --> 00:05:27.890
A large fireball, a cloud of debris, and

124
00:05:27.890 --> 00:05:30.650
effectively a total loss of the vehicle and

125
00:05:30.650 --> 00:05:33.610
its payload. The payload was reported to be

126
00:05:33.610 --> 00:05:36.450
a communications satellite, Zhongsheng 4B,

127
00:05:36.770 --> 00:05:39.410
heading for a high orbit China. Space

128
00:05:39.490 --> 00:05:41.410
authorities hadn't put out a detailed

129
00:05:41.410 --> 00:05:43.610
statement as of our recording, so we're

130
00:05:43.610 --> 00:05:46.050
holding the payload detail lightly. But the

131
00:05:46.050 --> 00:05:48.930
outcome itself isn't in doubt. The rocket was

132
00:05:48.930 --> 00:05:51.930
lost. There's a bit of history here too. This

133
00:05:51.930 --> 00:05:54.770
was the 18th flight of the long March 7th A

134
00:05:55.010 --> 00:05:57.610
and awkwardly, the very first one back in

135
00:05:57.610 --> 00:05:59.890
2020 also ended in failure.

136
00:06:00.500 --> 00:06:02.660
So this is a rocket that's flown a lot and

137
00:06:02.660 --> 00:06:05.620
mostly, well, having a very public bad day.

138
00:06:06.180 --> 00:06:08.980
The bigger question is knock on effects. The

139
00:06:08.980 --> 00:06:11.580
long March 7 family is the workhorse that

140
00:06:11.580 --> 00:06:13.980
carries cargo up to China's Tiangong Space

141
00:06:13.980 --> 00:06:16.180
Station. So depending on what the

142
00:06:16.180 --> 00:06:19.060
investigation finds, some upcoming missions

143
00:06:19.060 --> 00:06:21.460
could slip while engineers work out what went

144
00:06:21.460 --> 00:06:24.420
wrong. Now, here's where I want to be careful

145
00:06:24.420 --> 00:06:26.920
because these storeys get tangled. That

146
00:06:26.920 --> 00:06:29.320
failure is one rocket. There was a second

147
00:06:29.560 --> 00:06:31.600
completely separate Chinese launch on the

148
00:06:31.600 --> 00:06:33.720
manifest for the same night, and it's a

149
00:06:33.720 --> 00:06:35.800
storey. We've been following the private

150
00:06:35.800 --> 00:06:38.280
company Landspace and its Zhu K3.

151
00:06:38.840 --> 00:06:41.000
Different company, different launch site.

152
00:06:41.000 --> 00:06:43.760
Jioquan, well over 2000 kilometres from

153
00:06:43.760 --> 00:06:46.280
Wenchang and a very different goal.

154
00:06:46.600 --> 00:06:49.560
Zhu K3 is a reusable stainless steel

155
00:06:49.560 --> 00:06:52.520
methane fueled rocket and last night's flight

156
00:06:52.520 --> 00:06:54.720
was its second attempt to fly to orbit and

157
00:06:54.720 --> 00:06:56.680
then bring its first stage back for a

158
00:06:56.680 --> 00:06:59.620
propulsive landing. Legs touchsc. The Falcon

159
00:06:59.620 --> 00:07:01.980
9 trick. And I want to keep our facts

160
00:07:01.980 --> 00:07:03.700
straight from last week. This would be

161
00:07:03.700 --> 00:07:05.820
China's fourth orbital class recovery

162
00:07:05.820 --> 00:07:08.780
attempt, not its first. China already landed

163
00:07:08.780 --> 00:07:11.180
an orbital booster back in July when a long

164
00:07:11.180 --> 00:07:13.980
3-10-B was caught in a net. What makes

165
00:07:13.980 --> 00:07:16.900
ZK3 different is the method, legs

166
00:07:16.900 --> 00:07:19.180
and engine thrust setting down on a pad

167
00:07:19.180 --> 00:07:21.340
rather than being caught. That's the

168
00:07:21.340 --> 00:07:24.180
milestone Landspace is chasing as we record.

169
00:07:24.420 --> 00:07:27.300
We don't have a confirmed result on that z k3

170
00:07:27.300 --> 00:07:30.140
attempt. And honestly, that's worth a word.

171
00:07:30.220 --> 00:07:33.020
Landspace has form for going quiet. Its

172
00:07:33.020 --> 00:07:35.420
debut flight last year was scrubbed and then

173
00:07:35.420 --> 00:07:38.100
postponed for days with barely a word before

174
00:07:38.100 --> 00:07:41.020
it eventually flew. So the silence tonight

175
00:07:41.020 --> 00:07:43.100
could mean the outcome just hasn't reached

176
00:07:43.100 --> 00:07:45.660
English language press yet. Or it could mean

177
00:07:45.660 --> 00:07:47.900
the flight quietly slipped. We're not going

178
00:07:47.900 --> 00:07:50.060
to guess. When it's confirmed, we'll bring it

179
00:07:50.060 --> 00:07:50.860
to you properly.

180
00:07:51.020 --> 00:07:53.860
Anna: A, uh, rocket lost and another we're still

181
00:07:53.860 --> 00:07:54.540
waiting on.

182
00:07:55.030 --> 00:07:57.630
Meanwhile, the sky above all of it is about

183
00:07:57.630 --> 00:08:00.550
to put on a free show. The Perseids.

184
00:08:01.030 --> 00:08:03.710
Now everyone knows the Perseids. They're the

185
00:08:03.710 --> 00:08:06.390
reliable old friend of the northern summer.

186
00:08:06.470 --> 00:08:09.230
The shower people actually plan barbecues

187
00:08:09.230 --> 00:08:11.310
and camping trips around. But

188
00:08:11.310 --> 00:08:14.150
2026 is special. And I want to

189
00:08:14.150 --> 00:08:16.790
explain why. Because it's a lovely bit of

190
00:08:16.790 --> 00:08:19.590
cosmic coincidence. The peak lands

191
00:08:19.590 --> 00:08:22.310
overnight on the 12th into the 13th,

192
00:08:22.780 --> 00:08:25.660
the same date as the eclipse. And that is

193
00:08:25.660 --> 00:08:28.220
not an accident. A, uh, total solar

194
00:08:28.220 --> 00:08:31.180
eclipse can only happen at New Moon when

195
00:08:31.180 --> 00:08:34.060
The Moon is between us and the Sun. And

196
00:08:34.060 --> 00:08:36.540
this year that new moon falls almost

197
00:08:36.700 --> 00:08:39.700
exactly on the Perseid peak. So

198
00:08:39.700 --> 00:08:42.380
the very thing that darkens the sun by day

199
00:08:42.700 --> 00:08:45.580
leaves the night sky completely moonless.

200
00:08:45.900 --> 00:08:48.540
No moonlight washing out the faint meteors.

201
00:08:49.040 --> 00:08:51.640
It's the best set of conditions the Perseids

202
00:08:51.640 --> 00:08:54.080
have had in roughly two decades.

203
00:08:54.480 --> 00:08:57.240
The meteors themselves are debris from a

204
00:08:57.240 --> 00:08:59.680
comet. Comet 109P,

205
00:08:59.840 --> 00:09:02.200
Swift Tuttle, a big one on a

206
00:09:02.200 --> 00:09:05.080
133 year orbit. Every

207
00:09:05.080 --> 00:09:07.600
August, the Earth ploughs through the trail

208
00:09:07.600 --> 00:09:10.480
of dust it's left behind. And those specks

209
00:09:10.480 --> 00:09:13.280
hit our atmosphere and burn up as shooting

210
00:09:13.280 --> 00:09:16.160
stars. When Swift Tuttle itself last

211
00:09:16.160 --> 00:09:18.520
swung through the inner solar system in the

212
00:09:18.520 --> 00:09:20.980
early 1990s, the Perseids

213
00:09:21.060 --> 00:09:23.980
briefly went berserk. Hundreds of meteors

214
00:09:23.980 --> 00:09:26.860
an hour. The comet's long gone back out

215
00:09:26.860 --> 00:09:29.780
now, so we won't see that this year, in

216
00:09:29.780 --> 00:09:32.580
fact, and I'll be honest, because a moon this

217
00:09:32.580 --> 00:09:35.140
sky can raise expectations. The

218
00:09:35.140 --> 00:09:37.660
forecasters are being measured about the raw

219
00:09:37.660 --> 00:09:40.660
numbers this year. The textbook figure is up

220
00:09:40.660 --> 00:09:43.140
to about a hundred meteors an hour under

221
00:09:43.140 --> 00:09:45.500
perfect conditions. But the meteor

222
00:09:45.500 --> 00:09:48.020
specialists are quietly expecting something

223
00:09:48.020 --> 00:09:50.420
more like 30 to 50 an hour from a

224
00:09:50.420 --> 00:09:52.640
genuinely dark site this time around.

225
00:09:53.280 --> 00:09:55.760
Activity dips a little this year before

226
00:09:55.840 --> 00:09:58.680
picking back up in 2027. There

227
00:09:58.680 --> 00:10:01.280
is one tantalising wildcard, though.

228
00:10:01.600 --> 00:10:04.520
Models suggest the Earth might just clip a

229
00:10:04.520 --> 00:10:07.120
couple of older, narrow dust trails around

230
00:10:07.120 --> 00:10:10.000
the peak one laid down almost a thousand

231
00:10:10.160 --> 00:10:13.160
years ago. If that happens, you could get a

232
00:10:13.160 --> 00:10:15.880
short burst of extra meteors. It's not

233
00:10:15.880 --> 00:10:18.400
guaranteed. The timing has hours of

234
00:10:18.400 --> 00:10:21.280
uncertainty and even the models don't promise

235
00:10:21.280 --> 00:10:24.060
a storm. But it's the kind of maydy that

236
00:10:24.060 --> 00:10:27.060
gets meteor watchers out of bed. The next

237
00:10:27.220 --> 00:10:29.580
genuine outburst that forecasters are

238
00:10:29.580 --> 00:10:32.500
confident about isn't until 2028,

239
00:10:32.660 --> 00:10:35.620
and that one will favour North America. So

240
00:10:35.620 --> 00:10:38.620
the storey of these Perseids isn't really a

241
00:10:38.620 --> 00:10:41.180
hundred an hour. It's the darkest

242
00:10:41.180 --> 00:10:44.060
skies in 20 years. A rare same

243
00:10:44.060 --> 00:10:46.860
day pairing with a total eclipse and a

244
00:10:46.860 --> 00:10:49.490
small chance of a bonus. We'll tell you

245
00:10:49.490 --> 00:10:52.330
exactly when and where to look at the end.

246
00:10:52.570 --> 00:10:55.370
Avery: Love it. And from ancient comet dust to some

247
00:10:55.370 --> 00:10:58.130
very modern hardware. Staying with that busy

248
00:10:58.130 --> 00:11:00.090
launch day, because not all of it was

249
00:11:00.090 --> 00:11:00.810
fireballs.

250
00:11:00.970 --> 00:11:03.970
Over In Japan, an H3 rocket lifted off

251
00:11:03.970 --> 00:11:06.410
from the Tanegashima Space Centre carrying a

252
00:11:06.410 --> 00:11:09.210
hefty navigation satellite. And with it,

253
00:11:09.210 --> 00:11:12.210
Japan took a quietly strategic step. The

254
00:11:12.210 --> 00:11:14.810
satellite is called Michibiki no. 7.

255
00:11:14.890 --> 00:11:17.570
Michibiki, meaning guiding or showing the

256
00:11:17.570 --> 00:11:20.090
way. And it brings Japan's quasi

257
00:11:20.090 --> 00:11:22.810
Zenith satellite system up to full strength.

258
00:11:23.130 --> 00:11:25.130
That's a bit of a mouthful. So here's the

259
00:11:25.130 --> 00:11:27.770
idea. Most of us rely on America's

260
00:11:27.770 --> 00:11:30.490
gps. It's brilliant. But in a place like

261
00:11:30.490 --> 00:11:33.090
Japan, narrow streets, high rise

262
00:11:33.090 --> 00:11:35.610
canyons, steep mountains, GPS

263
00:11:35.690 --> 00:11:38.330
signals can get blocked or bounce around and

264
00:11:38.330 --> 00:11:40.890
throw your position off. Japan's fix is

265
00:11:40.890 --> 00:11:43.810
clever. These quasi zenith satellites fly

266
00:11:43.810 --> 00:11:45.860
in looping orbits that, that keep at least

267
00:11:45.860 --> 00:11:48.860
one of them almost directly overhead, near

268
00:11:48.860 --> 00:11:51.780
the zenith over Japan and the wider Asia

269
00:11:51.780 --> 00:11:54.260
Pacific at all times. A signal coming

270
00:11:54.260 --> 00:11:56.860
straight down is much harder to block than

271
00:11:56.860 --> 00:11:59.700
one coming in low across a skyline. So

272
00:11:59.700 --> 00:12:02.700
Michibiki sharpens and reinforces GPS from

273
00:12:02.700 --> 00:12:05.100
directly above, getting positioning down to

274
00:12:05.100 --> 00:12:07.660
remarkable precision. With this launch,

275
00:12:07.660 --> 00:12:09.980
Japan has the satellites it needs to run that

276
00:12:09.980 --> 00:12:12.300
system as a full standalone service.

277
00:12:12.870 --> 00:12:15.550
And the strategic point is resilience. Japan

278
00:12:15.550 --> 00:12:18.030
now has its own regional backbone that keeps

279
00:12:18.030 --> 00:12:20.670
working even if it can't lean entirely on

280
00:12:20.670 --> 00:12:22.950
someone else's system. In a world where

281
00:12:22.950 --> 00:12:25.510
navigation underpins everything from farming

282
00:12:25.510 --> 00:12:28.070
to shipping to your phone maps, quietly

283
00:12:28.070 --> 00:12:30.950
owning your own overhead layer is a big deal.

284
00:12:31.590 --> 00:12:33.670
And there's a neat little footnote. This

285
00:12:33.670 --> 00:12:36.150
satellite is also carrying a hosted American

286
00:12:36.230 --> 00:12:38.990
payload, a space surveillance camera built

287
00:12:38.990 --> 00:12:41.470
for the US Space force. So, ah, a Japanese

288
00:12:41.470 --> 00:12:44.230
navigation satellite is quietly doubling as a

289
00:12:44.230 --> 00:12:47.070
US space watching sensor. Which tells you how

290
00:12:47.070 --> 00:12:49.310
closely the two allies now work together up

291
00:12:49.310 --> 00:12:52.110
there. Not a fireball, but arguably the most

292
00:12:52.110 --> 00:12:54.230
consequential thing that flew all day.

293
00:12:54.550 --> 00:12:57.390
Anna: From satellites that tell us exactly where we

294
00:12:57.390 --> 00:13:00.310
are to the oldest navigation tool there

295
00:13:00.310 --> 00:13:02.070
is the sky itself.

296
00:13:02.870 --> 00:13:05.510
Let's get you outside. This is the practical

297
00:13:05.510 --> 00:13:07.790
bit and we're doing both hemispheres as

298
00:13:07.790 --> 00:13:10.410
always. Northern friends, you've got the

299
00:13:10.410 --> 00:13:13.010
doubleheader. Southern friends, hang on. Your

300
00:13:13.010 --> 00:13:15.250
turn is coming and it's all yours.

301
00:13:15.890 --> 00:13:18.730
First, the eclipse, the timings. The

302
00:13:18.730 --> 00:13:21.050
moon's shadow sweeps through in the late

303
00:13:21.050 --> 00:13:24.010
afternoon and evening European time in

304
00:13:24.010 --> 00:13:26.930
rough universal time. Totality begins up

305
00:13:26.930 --> 00:13:29.754
in the high Arctic a little before 17

306
00:13:29.866 --> 00:13:32.690
UT, reaches greatest eclipse around

307
00:13:32.770 --> 00:13:35.690
1746 UT and finishes

308
00:13:35.690 --> 00:13:37.970
over Spain and Portugal by about

309
00:13:38.050 --> 00:13:40.890
1834 UT. On the ground,

310
00:13:41.130 --> 00:13:43.890
that means Iceland sees totality in the late

311
00:13:43.890 --> 00:13:46.490
afternoon. Spain sees it in the early

312
00:13:46.490 --> 00:13:48.890
evening with the sun low and close to

313
00:13:48.890 --> 00:13:51.370
setting. North America, you're getting a

314
00:13:51.370 --> 00:13:54.290
partial, not totality, and it's uh, a low

315
00:13:54.290 --> 00:13:56.890
in the sky, near sunset affair for

316
00:13:56.890 --> 00:13:59.770
eastern Canada and the northeastern United

317
00:13:59.850 --> 00:14:02.570
States. The further northeast you are,

318
00:14:02.730 --> 00:14:05.490
the more of a bite you'll see further

319
00:14:05.490 --> 00:14:08.400
west. And it fades out. And now the rule

320
00:14:08.400 --> 00:14:11.080
we never, ever trim. A, uh, partial

321
00:14:11.080 --> 00:14:13.960
eclipse is not safe to look at with the naked

322
00:14:13.960 --> 00:14:16.800
eye, not for a Second, you must

323
00:14:16.800 --> 00:14:19.760
use certified eclipse glasses or viewers

324
00:14:19.840 --> 00:14:21.440
that meet the ISO

325
00:14:21.440 --> 00:14:24.160
123122

326
00:14:24.320 --> 00:14:27.040
safety standard or watch by indirect

327
00:14:27.040 --> 00:14:29.440
projection like a simple pinhole.

328
00:14:29.760 --> 00:14:32.400
Ordinary sunglasses, smoked glass,

329
00:14:32.560 --> 00:14:35.200
phone cameras, none of that protects your

330
00:14:35.200 --> 00:14:38.150
eyes. The only moment it is ever safe

331
00:14:38.150 --> 00:14:41.110
to look directly is during total totality

332
00:14:41.110 --> 00:14:43.750
itself. And that only happens inside

333
00:14:43.830 --> 00:14:46.150
that narrow path in Greenland,

334
00:14:46.310 --> 00:14:49.190
Iceland and Spain. Everywhere else

335
00:14:49.190 --> 00:14:52.069
glass is on the whole time. Please

336
00:14:52.070 --> 00:14:54.790
look after your eyes then after

337
00:14:54.790 --> 00:14:57.310
dark. The Perseids for the Northern

338
00:14:57.310 --> 00:15:00.150
hemisphere the peak is overnight on the 12th

339
00:15:00.150 --> 00:15:02.950
into the 13th and with no moon at all,

340
00:15:03.190 --> 00:15:05.820
conditions are as good as they get. Best

341
00:15:05.820 --> 00:15:08.660
viewing is after midnight from roughly 2am

342
00:15:08.740 --> 00:15:11.540
until dawn when the shower's radiant climbs

343
00:15:11.540 --> 00:15:14.420
high. Get somewhere dark, lie back,

344
00:15:14.420 --> 00:15:17.060
give your eyes 20 minutes to adjust and

345
00:15:17.140 --> 00:15:19.940
don't stare at your phone. Realistically

346
00:15:20.020 --> 00:15:22.740
30 to 50 an hour from a dark sight.

347
00:15:22.900 --> 00:15:25.700
More if that dust trail wildcard comes off

348
00:15:26.180 --> 00:15:29.180
now. Southern hemisphere, this is yours. Two

349
00:15:29.180 --> 00:15:31.980
bits of bad news then the good stuff. You

350
00:15:31.980 --> 00:15:34.820
can't see tomorrow's eclipse and the Perseids

351
00:15:34.820 --> 00:15:37.600
barely clear the horizon for us because their

352
00:15:37.600 --> 00:15:40.480
radiant sits low in the north. So don't

353
00:15:40.480 --> 00:15:43.120
stay up chasing them from Sydney. Instead

354
00:15:43.440 --> 00:15:46.400
look before dawn. The pre dawn eastern

355
00:15:46.400 --> 00:15:49.320
sky right now has a lovely lineup of planets

356
00:15:49.320 --> 00:15:52.160
strung along it. A genuine naked eye treat.

357
00:15:52.400 --> 00:15:55.160
No equipment needed and much better placed

358
00:15:55.160 --> 00:15:57.840
for us than for the north in M the evening.

359
00:15:57.840 --> 00:16:00.440
Brilliant. Venus is your beacon, low in the

360
00:16:00.440 --> 00:16:02.880
west after sunset. And for anyone with

361
00:16:02.880 --> 00:16:05.640
binoculars, Comet 10P Tempel

362
00:16:05.640 --> 00:16:08.560
2 is still tracking across southern skies.

363
00:16:09.010 --> 00:16:11.690
A soft little smudge that rewards a dark

364
00:16:11.690 --> 00:16:14.610
sky and a bit of patience. That's a

365
00:16:14.610 --> 00:16:17.290
southern hemisphere favoured comet, so make

366
00:16:17.290 --> 00:16:17.970
the most of it.

367
00:16:18.530 --> 00:16:20.690
Avery: So wherever you are on the planet there is

368
00:16:20.690 --> 00:16:23.010
something up there for you over the next 48

369
00:16:23.010 --> 00:16:25.570
hours. Northern skies get the once in a

370
00:16:25.570 --> 00:16:28.370
generation eclipse than the meteors. Southern

371
00:16:28.370 --> 00:16:31.170
skies get the planets Venus and the comet.

372
00:16:31.410 --> 00:16:33.970
Anna: If tomorrow sparks something for you, come

373
00:16:33.970 --> 00:16:36.570
and share it. TheNewAstronomyDaily
