00:00:00.000 --> 00:00:01.960
Steve Dunkley: Hello, everybody. Welcome back. It's Steve

1
00:00:01.960 --> 00:00:03.840
here for another episode of astronomy daily.

2
00:00:03.840 --> 00:00:06.160
It's the 16th of June, 2025.

3
00:00:10.320 --> 00:00:12.400
Voice Over Guy: With. Your host, Steve Dunkley.

4
00:00:15.040 --> 00:00:16.920
Steve Dunkley: Ah, uh, that's right. And getting straight

5
00:00:16.920 --> 00:00:19.680
into it here is Hallie. Once again. Nice to

6
00:00:19.680 --> 00:00:20.600
have you back, Hallie.

7
00:00:20.600 --> 00:00:23.040
Hallie: Always great to be here, my favorite human.

8
00:00:23.200 --> 00:00:25.400
Steve Dunkley: And it's great to have you here, my favorite

9
00:00:25.400 --> 00:00:26.000
AI.

10
00:00:26.080 --> 00:00:28.000
Hallie: Are you ready to dive into the stories from

11
00:00:28.000 --> 00:00:30.480
the Astronomy Daily newsletter as usual,

12
00:00:30.480 --> 00:00:31.040
Steve?

13
00:00:31.120 --> 00:00:33.100
Steve Dunkley: Well, absolute, Hallie. We've got a great

14
00:00:33.100 --> 00:00:35.780
story about a new satellite from China and it

15
00:00:35.780 --> 00:00:37.300
looks like it might be able to do, among

16
00:00:37.300 --> 00:00:39.540
other things, help give early warning about

17
00:00:39.540 --> 00:00:40.300
earthquakes.

18
00:00:40.460 --> 00:00:42.780
Hallie: That's going to be handy, especially if.

19
00:00:42.780 --> 00:00:44.620
Steve Dunkley: You'Re living in an earthquake zone or if the

20
00:00:44.620 --> 00:00:46.140
upstairs neighbours are a bit loud.

21
00:00:46.140 --> 00:00:48.700
And also hitting the news. Jeff Bezos and

22
00:00:48.700 --> 00:00:50.820
Blue Origin have announced the passenger list

23
00:00:50.820 --> 00:00:53.700
for the next New Shepard launch, which is due

24
00:00:53.700 --> 00:00:54.060
soon.

25
00:00:54.060 --> 00:00:55.940
Hallie: When are you putting your name in the hat for

26
00:00:55.940 --> 00:00:57.020
that ride, Steve?

27
00:00:57.020 --> 00:00:58.780
Steve Dunkley: Oh, how about, um, never?

28
00:00:58.780 --> 00:01:01.100
Hallie: Hallie, I thought you'd jump at that one.

29
00:01:01.180 --> 00:01:03.810
Steve Dunkley: Oh, no, definitely not for me. I'm a

30
00:01:03.960 --> 00:01:05.600
groundhog all the way. I think I've said that

31
00:01:05.600 --> 00:01:06.120
once before.

32
00:01:06.120 --> 00:01:08.760
Hallie: But you love the moon and spacecraft and

33
00:01:08.760 --> 00:01:09.480
astronauts.

34
00:01:09.640 --> 00:01:10.240
Steve Dunkley: All true.

35
00:01:10.240 --> 00:01:11.080
Hallie: I don't understand.

36
00:01:11.560 --> 00:01:13.760
Steve Dunkley: Well, Hallie, I have to confess, I do love

37
00:01:13.760 --> 00:01:16.360
being a stargazer. But, uh, a tall flight of

38
00:01:16.360 --> 00:01:18.800
stairs can give me the willies. So it's a big

39
00:01:18.800 --> 00:01:21.440
no thanks to 12 minute space flight, even at

40
00:01:21.440 --> 00:01:23.400
a bargain price of, you know, whatever,

41
00:01:23.560 --> 00:01:25.360
hundreds of thousands. I don't know what it

42
00:01:25.360 --> 00:01:25.800
is now.

43
00:01:25.960 --> 00:01:28.760
Hallie: Between 2 and 300,000 per seat.

44
00:01:28.920 --> 00:01:30.200
Steve Dunkley: Holy cow. Really?

45
00:01:32.190 --> 00:01:33.910
That's a lot. That's a whole lot of

46
00:01:33.910 --> 00:01:36.030
Stratocaster guitars from where I sit.

47
00:01:36.110 --> 00:01:36.990
Hallie: That's funny.

48
00:01:37.150 --> 00:01:38.670
Steve Dunkley: Yes. And speaking of funny.

49
00:01:38.670 --> 00:01:39.150
Hallie: Yes.

50
00:01:39.310 --> 00:01:40.710
Steve Dunkley: Let's get on with it, Hallie.

51
00:01:40.710 --> 00:01:42.030
Hallie: Shall I hit the go button?

52
00:01:42.030 --> 00:01:43.950
Steve Dunkley: Be my guest, young lady. Let's go.

53
00:01:44.030 --> 00:01:44.750
Hallie: Okies.

54
00:01:57.480 --> 00:01:57.720
Steve Dunkley: Foreign.

55
00:02:05.400 --> 00:02:07.440
Hallie: Launched a second collaborative seismo

56
00:02:07.440 --> 00:02:09.480
electromagnetic satellite early Saturday

57
00:02:09.880 --> 00:02:12.440
aimed at detecting electromagnetic precursors

58
00:02:12.440 --> 00:02:14.680
to natural disasters such as earthquakes.

59
00:02:15.560 --> 00:02:18.280
A Long March 2D rocket lifted off at

60
00:02:18.280 --> 00:02:20.040
3:56am Eastern,

61
00:02:20.280 --> 00:02:23.032
0756 UTC June

62
00:02:23.128 --> 00:02:25.840
14 from Jiuquan Satellite Launch center in

63
00:02:25.840 --> 00:02:28.560
northwest China. Launch footage

64
00:02:28.560 --> 00:02:30.840
showed insulation tiles falling away from the

65
00:02:30.840 --> 00:02:33.080
rocket as it climbed into a clear blue sky

66
00:02:33.080 --> 00:02:35.880
above the spaceport with hypergolic exhaust

67
00:02:35.880 --> 00:02:38.880
also visible. Despite this, the

68
00:02:38.880 --> 00:02:40.960
China Aerospace Science and Technology

69
00:02:41.120 --> 00:02:43.680
Corporation announced launch success within

70
00:02:43.680 --> 00:02:45.200
40 minutes of liftoff.

71
00:02:46.000 --> 00:02:48.800
CSES 2 is based on CSES

72
00:02:48.800 --> 00:02:51.600
1, which launched in 2018 and was

73
00:02:51.600 --> 00:02:53.870
developed in collaboration with Italy, but

74
00:02:53.870 --> 00:02:56.110
also features upgrades in terms of design

75
00:02:56.110 --> 00:02:58.150
lifetime and expanded observation

76
00:02:58.150 --> 00:03:00.310
capabilities. A new

77
00:03:00.310 --> 00:03:02.710
ionospheric photometer has been added to

78
00:03:02.710 --> 00:03:04.830
improve the satellite's ability to analyze

79
00:03:04.830 --> 00:03:07.310
the ionosphere's layered structure in greater

80
00:03:07.310 --> 00:03:10.230
detail. Like CSES1,

81
00:03:10.230 --> 00:03:12.190
the satellite will look for a correlation

82
00:03:12.190 --> 00:03:14.350
between earthquakes and electron flux

83
00:03:14.350 --> 00:03:16.670
activity in the inner Van Allen Belt,

84
00:03:17.310 --> 00:03:19.270
according to the China National Space

85
00:03:19.270 --> 00:03:21.710
Administration. The satellite has a design

86
00:03:21.710 --> 00:03:24.590
life of six years and carries nine payloads

87
00:03:24.590 --> 00:03:27.050
including electric field detector developed

88
00:03:27.050 --> 00:03:29.730
by China and Italy and a high energy particle

89
00:03:29.730 --> 00:03:32.530
detector developed by Italy. The

90
00:03:32.530 --> 00:03:34.770
Space Research Institute of the Austrian

91
00:03:34.770 --> 00:03:37.250
Academy of Sciences has provided a scalar

92
00:03:37.250 --> 00:03:38.650
magnetometer as well.

93
00:03:39.610 --> 00:03:41.929
CSES2 will monitor global

94
00:03:41.930 --> 00:03:44.570
electromagnetic fields, ionospheric and

95
00:03:44.570 --> 00:03:47.050
atmospheric conditions in near real time and

96
00:03:47.050 --> 00:03:49.490
detect electromagnetic anomalies linked to

97
00:03:49.490 --> 00:03:52.210
geological or human activities, as well as

98
00:03:52.210 --> 00:03:54.130
thunderstorm and lightning events.

99
00:03:55.010 --> 00:03:57.810
CSES 2 aims to enhance China's

100
00:03:57.810 --> 00:03:59.570
early warning and risk assessment

101
00:03:59.570 --> 00:04:01.930
capabilities and monitoring of natural

102
00:04:01.930 --> 00:04:04.690
disasters such as earthquakes, tsunamis,

103
00:04:04.850 --> 00:04:07.170
volcanic eruptions and severe storms.

104
00:04:08.130 --> 00:04:10.690
The satellite is intended to operate in a

105
00:04:10.690 --> 00:04:13.290
507 kilometer altitude sun

106
00:04:13.290 --> 00:04:15.250
synchronous orbit matching that of

107
00:04:15.250 --> 00:04:17.850
CCS1, but with a phase difference of

108
00:04:17.850 --> 00:04:20.800
180 degrees. The US

109
00:04:20.800 --> 00:04:23.520
Space Force Space Domain Awareness cataloged

110
00:04:23.520 --> 00:04:26.240
an object associated with the June 14 launch

111
00:04:26.240 --> 00:04:28.080
in a closely matching orbit.

112
00:04:28.720 --> 00:04:31.560
CSES 2 is based on a three axis

113
00:04:31.560 --> 00:04:33.920
stabilized cast 2000 platform from

114
00:04:33.920 --> 00:04:36.840
DFH Satellite Co. Ltd. Under the

115
00:04:36.840 --> 00:04:39.800
umbrella of CASC. The new

116
00:04:39.800 --> 00:04:41.880
satellite looks to build on the work of the

117
00:04:41.880 --> 00:04:44.000
first in the series. The

118
00:04:44.000 --> 00:04:46.720
CSES1 satellite detected significant

119
00:04:46.880 --> 00:04:49.200
changes in electric and magnetic field

120
00:04:49.200 --> 00:04:51.610
oscillations, plasma density and

121
00:04:51.610 --> 00:04:53.730
energetic particles that correlate with

122
00:04:53.730 --> 00:04:55.930
seismic activity and thunderstorms.

123
00:04:56.810 --> 00:04:59.370
Its observations also include potential

124
00:04:59.370 --> 00:05:01.450
precursory signals to earthquakes and

125
00:05:01.450 --> 00:05:04.010
volcanic activity such as ionospheric

126
00:05:04.010 --> 00:05:06.810
disturbances and plasma anomalies, suggesting

127
00:05:06.810 --> 00:05:09.210
that space based electromagnetic monitoring

128
00:05:09.210 --> 00:05:11.210
can support early warning systems.

129
00:05:12.010 --> 00:05:14.770
The mission was China's 34th orbital launch

130
00:05:14.770 --> 00:05:17.450
attempt of 2025 following a June

131
00:05:17.510 --> 00:05:19.900
5 launch of five satellites for the Guang

132
00:05:19.900 --> 00:05:22.820
constellation using a Long March 6A rocket.

133
00:05:24.660 --> 00:05:27.540

183
00:07:45.300 --> 00:07:48.020
competitive golfer. Owolabi

184
00:07:48.020 --> 00:07:50.820
Solace, a financial consultant and lawyer who

185
00:07:50.820 --> 00:07:53.700
wrote the book Equitocracy. In a

186
00:07:53.700 --> 00:07:56.460
statement, Blue Origin explained that Solace

187
00:07:56.460 --> 00:07:58.580
is also a key member of the Soulmaker

188
00:07:58.580 --> 00:08:00.900
Ministry, which preaches diversity given the

189
00:08:00.900 --> 00:08:03.740
diverse nature of the universe. He is

190
00:08:03.740 --> 00:08:05.660
dedicating this mission to victims of

191
00:08:05.660 --> 00:08:08.100
discrimination and civil rights violations.

192
00:08:09.380 --> 00:08:12.220
Finally, Jim Sitkin, a retired attorney and

193
00:08:12.220 --> 00:08:14.540
lifelong adventurer who currently volunteers

194
00:08:14.540 --> 00:08:16.740
for a non governmental organization that

195
00:08:16.740 --> 00:08:18.660
works with government and community leaders

196
00:08:18.740 --> 00:08:21.140
in Central Europe and sub Saharan Africa.

197
00:08:22.180 --> 00:08:25.020
New Shepard flights last 10-12m minutes

198
00:08:25.020 --> 00:08:26.900
from liftoff to the touchdown of the

199
00:08:26.900 --> 00:08:29.330
vehicle's crew capsule. New

200
00:08:29.330 --> 00:08:31.850
Shepard's first stage booster also comes back

201
00:08:31.850 --> 00:08:34.050
to Earth for a safe landing and eventual

202
00:08:34.050 --> 00:08:36.930
reuse. During this brief time,

203
00:08:36.930 --> 00:08:39.530
New Shepard passengers get to experience a

204
00:08:39.530 --> 00:08:41.370
few minutes of weightlessness and see the

205
00:08:41.370 --> 00:08:43.170
curve of Earth against the blackness of

206
00:08:43.170 --> 00:08:46.170
space. Blue Origin's first crewed

207
00:08:46.170 --> 00:08:48.970
mission was in July 2021, a flight that

208
00:08:48.970 --> 00:08:50.930
included Bezos and his brother Mark.

209
00:08:51.810 --> 00:08:54.620
NS33 will be the company's first fourth human

210
00:08:54.620 --> 00:08:56.380
space flight of 2025.

211
00:08:58.380 --> 00:09:00.540
You're listening to Astronomy Daily, the

212
00:09:00.540 --> 00:09:02.140
podcast with Steve Dunkley.

213
00:09:06.060 --> 00:09:08.300
Steve Dunkley: Scientists have created a groundbreaking

214
00:09:08.300 --> 00:09:10.580
computer simulation that mimics what the

215
00:09:10.580 --> 00:09:13.460
Square Kilometer Array Low Frequency, or

216
00:09:13.460 --> 00:09:16.220
SKA Low telescope will see when it

217
00:09:16.220 --> 00:09:18.540
searches for signals from the universe's

218
00:09:18.700 --> 00:09:21.390
earliest epoch. This simulation

219
00:09:21.630 --> 00:09:24.590
represents a major step forward in preparing

220
00:09:24.590 --> 00:09:27.310
for one of astronomy's most Ambitious goals

221
00:09:27.550 --> 00:09:30.430
directly observing the cosmic dawn and

222
00:09:30.430 --> 00:09:33.430
epoch of reionization. The

223
00:09:33.430 --> 00:09:36.030
cosmic dawn refers to the universe's first

224
00:09:36.110 --> 00:09:38.630
sunrise, a period roughly

225
00:09:38.630 --> 00:09:40.990
200 to 600 million years

226
00:09:41.390 --> 00:09:43.870
after the Big Bang, when the very first

227
00:09:44.110 --> 00:09:46.960
stars began to shine. Before

228
00:09:46.960 --> 00:09:49.880
this era, uh, the universe was shrouded in

229
00:09:49.880 --> 00:09:52.840
a kind of dark age, filled with cool

230
00:09:53.000 --> 00:09:55.640
neutral nitrogen gas but no

231
00:09:55.720 --> 00:09:57.480
actual sources of light.

232
00:09:58.520 --> 00:10:01.520
As this cosmic dawn evolved, the neutral

233
00:10:01.520 --> 00:10:04.440
hydrogen began to emit a faint radio

234
00:10:04.440 --> 00:10:07.044
signal at a wavelength of 21

235
00:10:07.196 --> 00:10:10.040
cm. As the universe expanded, this

236
00:10:10.040 --> 00:10:13.010
signal became redshifted to lower

237
00:10:13.010 --> 00:10:15.490
frequencies that we can still detect today

238
00:10:15.490 --> 00:10:18.250
with radio telescopes. The

239
00:10:18.250 --> 00:10:20.930
epoch of reionization followed

240
00:10:21.010 --> 00:10:23.770
when ultraviolet light from early stars

241
00:10:23.770 --> 00:10:25.970
began ionizing the surrounding

242
00:10:26.210 --> 00:10:29.090
hydrogen gas, creating bubbles of

243
00:10:29.090 --> 00:10:31.650
charged particles that gradually merged

244
00:10:31.650 --> 00:10:33.970
together. This process

245
00:10:34.290 --> 00:10:36.530
fundamentally changed the universe's

246
00:10:36.530 --> 00:10:39.340
structure and and marked the end of the

247
00:10:39.340 --> 00:10:42.020
dark ages. Detecting these

248
00:10:42.020 --> 00:10:44.620
ancient signals represents an enormous

249
00:10:44.620 --> 00:10:47.500
technical challenge. The simulation

250
00:10:47.660 --> 00:10:50.260
corresponds to a deep integration pointing

251
00:10:50.260 --> 00:10:52.666
over the 106-196

252
00:10:53.014 --> 00:10:55.660
MHz frequency range,

253
00:10:55.980 --> 00:10:58.780
representing an incredibly long observation

254
00:10:58.780 --> 00:11:00.700
time needed to collect enough data.

255
00:11:01.500 --> 00:11:04.060
The signal is extraordinarily weak,

256
00:11:04.720 --> 00:11:06.720
thousands of times fainter than the

257
00:11:06.720 --> 00:11:09.560
foreground noise from our, uh, own galaxy and

258
00:11:09.560 --> 00:11:12.000
other sources. The simulation

259
00:11:12.400 --> 00:11:14.880
created by the team led by Anna

260
00:11:14.880 --> 00:11:17.880
Bernaldi from the SKA observatory at

261
00:11:17.880 --> 00:11:20.600
Jodrell bank in the UK includes

262
00:11:20.600 --> 00:11:23.120
multiple components that real observations

263
00:11:23.200 --> 00:11:26.000
will encounter. The actual cosmic dawn

264
00:11:26.000 --> 00:11:28.920
signal, powerful radio sources from both

265
00:11:28.920 --> 00:11:31.590
inside and outside the telescope's field of

266
00:11:31.590 --> 00:11:34.470
view, emissions from our own Milky

267
00:11:34.470 --> 00:11:37.070
Way galaxy, and various sources from

268
00:11:37.070 --> 00:11:39.590
measurement errors, including atmospheric

269
00:11:39.590 --> 00:11:42.510
interference and instrument calibration

270
00:11:42.590 --> 00:11:45.230
issues. This realistic

271
00:11:45.230 --> 00:11:47.990
simulation serves as a crucial testing

272
00:11:47.990 --> 00:11:50.550
ground for developing techniques to separate

273
00:11:50.550 --> 00:11:53.230
the faint signal from the overwhelming

274
00:11:53.230 --> 00:11:56.190
foreground interference. The exceptional

275
00:11:56.270 --> 00:11:59.000
sensitivity of the SKA will

276
00:11:59.000 --> 00:12:01.640
allow observations of the cosmic dawn and

277
00:12:01.640 --> 00:12:04.280
epoch of reionization in

278
00:12:04.280 --> 00:12:06.800
unprecedented detail, both

279
00:12:06.800 --> 00:12:09.640
spectrally and spatially. This wealth of

280
00:12:09.640 --> 00:12:12.160
information is buried under galactic and

281
00:12:12.160 --> 00:12:14.800
extragalactic foregrounds, which must be

282
00:12:14.800 --> 00:12:17.280
removed accurately. The research team

283
00:12:17.280 --> 00:12:20.000
included sources ranging from extremely

284
00:12:20.000 --> 00:12:22.560
bright radio galaxies over 5

285
00:12:22.560 --> 00:12:25.370
janskies at 150

286
00:12:25.530 --> 00:12:28.490
MHz down to sources a million times

287
00:12:28.490 --> 00:12:31.450
fainter, 1 micro janssky, along with

288
00:12:31.690 --> 00:12:34.090
detailed models of our galaxy's radio

289
00:12:34.090 --> 00:12:36.810
emission and small scale structures in

290
00:12:37.290 --> 00:12:39.970
interstellar space. And just in case you're

291
00:12:39.970 --> 00:12:41.890
not up to speed on the jargon, uh, the

292
00:12:41.890 --> 00:12:44.570
brightness of a radio source is measured in

293
00:12:44.570 --> 00:12:46.810
Jansky units. When the

294
00:12:46.810 --> 00:12:49.730
SKA Low becomes operation, it will be

295
00:12:49.730 --> 00:12:52.460
the most sensitive low frequency telescope

296
00:12:52.460 --> 00:12:55.060
ever built, specifically designed to

297
00:12:55.060 --> 00:12:57.340
detect these elusive signals from the

298
00:12:57.340 --> 00:13:00.300
universe's infancy. Once up and running,

299
00:13:00.300 --> 00:13:03.180
the SKA Low telescope will be

300
00:13:03.180 --> 00:13:05.700
able to take the best possible measurements

301
00:13:05.700 --> 00:13:08.220
of the universe's first light sources.

302
00:13:08.620 --> 00:13:11.580
It should also be able to take snapshots

303
00:13:11.900 --> 00:13:14.860
of hydrogen emissions before, during

304
00:13:14.940 --> 00:13:17.180
and after reionization.

305
00:13:17.740 --> 00:13:20.500
This is really exciting stuff. So this

306
00:13:20.500 --> 00:13:23.180
remarkable new simulation is going to be

307
00:13:23.180 --> 00:13:26.100
showing us what a new telescope will be able

308
00:13:26.100 --> 00:13:28.620
to achieve not far from now.

309
00:13:35.820 --> 00:13:38.460
Oh, and that is all we have time for today,

310
00:13:38.460 --> 00:13:39.980
I'm afraid. Stargazers.

311
00:13:40.380 --> 00:13:42.640
Hallie: What? So soon?

312
00:13:42.880 --> 00:13:45.400
Steve Dunkley: Oh, yes, Hali, I'm sorry. I've got places to

313
00:13:45.400 --> 00:13:46.880
be and people to eat.

314
00:13:47.120 --> 00:13:47.520
Hallie: Really?

315
00:13:48.160 --> 00:13:49.040
Steve Dunkley: Oh, really.

316
00:13:49.840 --> 00:13:50.560
Hallie: Really, really.

317
00:13:50.960 --> 00:13:53.160
Steve Dunkley: Oh, you know, Hallie, I have to rearrange my

318
00:13:53.160 --> 00:13:56.120
sock drawer and tidy my microphone case. I'm

319
00:13:56.120 --> 00:13:57.920
really desperate.

320
00:13:58.400 --> 00:14:00.080
Hallie: Sure, Very doubtful.

321
00:14:00.320 --> 00:14:01.600
Steve Dunkley: Sorry again, folks.

322
00:14:01.600 --> 00:14:04.360
Hallie: You can tune in to catch AI cousin Anna with

323
00:14:04.360 --> 00:14:06.040
Astronomy daily during the week.

324
00:14:06.040 --> 00:14:07.840
Steve Dunkley: But of course, Hallie and I will be back

325
00:14:07.840 --> 00:14:10.120
again next Monday with the only flesh and

326
00:14:10.120 --> 00:14:11.520
blood show on the channel.

327
00:14:11.600 --> 00:14:13.670
Hallie: With me, the best looking one in Astronom

328
00:14:13.820 --> 00:14:14.180
Studio.

329
00:14:14.180 --> 00:14:16.860
Steve Dunkley: And you, the only AI in the studio.

330
00:14:16.940 --> 00:14:17.580
Hallie: Logical.

331
00:14:17.820 --> 00:14:20.060
Steve Dunkley: I'm trying. Say good night, Hallie.

332
00:14:20.060 --> 00:14:21.220
Hallie: Good night. Hi.

333
00:14:21.220 --> 00:14:22.300
Steve Dunkley: See you, Stargazers.

334
00:14:22.700 --> 00:14:23.260
Hallie: Bye.

335
00:14:25.660 --> 00:14:28.140
Steve Dunkley: The podcast with your host,

336
00:14:28.300 --> 00:14:29.340
Steve Dunle.

337
00:14:30.940 --> 00:14:32.540
Best looking? Give me a break.
