00:00:08.560 --> 00:00:11.240
Time, NASA names Dragonfly's
4
00:00:11.240 --> 00:00:13.840
landing site on the saturnian moon Titan.
5
00:00:14.400 --> 00:00:16.720
New clues about the Earth's moon's ancient
6
00:00:16.720 --> 00:00:19.680
magnetic field and why galaxies in the
7
00:00:19.680 --> 00:00:21.840
early universe look so weird.
8
00:00:22.480 --> 00:00:25.280
All that and more coming up on, um, Space
9
00:00:25.280 --> 00:00:28.040
Time. Welcome to
10
00:00:28.040 --> 00:00:30.160
Space Time with Stuart G.
11
00:00:46.460 --> 00:00:48.620
NASA has identified the landing site where
12
00:00:48.620 --> 00:00:51.020
its Dragonfly rotocopter, uh, will first
13
00:00:51.020 --> 00:00:53.660
touch down on the surface of the saturnian
14
00:00:53.660 --> 00:00:55.980
moon Titan. The target area
15
00:00:56.140 --> 00:00:58.540
comprises a large dune field with some inter
16
00:00:58.540 --> 00:01:00.980
dune terrain south of Silic Crater and
17
00:01:00.980 --> 00:01:02.820
stretches along the edge of a range of
18
00:01:02.820 --> 00:01:04.920
mountains or hills. The International
19
00:01:05.160 --> 00:01:07.320
Astronomical Union, the global body
20
00:01:07.400 --> 00:01:09.320
responsible for officially designating
21
00:01:09.320 --> 00:01:11.440
objects in space, has approved naming the
22
00:01:11.440 --> 00:01:14.320
region Amakik uh Andai. First part of
23
00:01:14.320 --> 00:01:16.440
the name is Mayan people appealed to the
24
00:01:16.440 --> 00:01:18.720
spirit Amakaq to stop strong winds from
25
00:01:18.720 --> 00:01:21.120
damaging their crops. The name literally
26
00:01:21.120 --> 00:01:23.600
translates into the one who locks up the
27
00:01:23.600 --> 00:01:26.280
wind. An ande aligns with the International
28
00:01:26.440 --> 00:01:28.920
Astronomical Union's convention of naming
29
00:01:28.920 --> 00:01:31.680
dune fields in Latin after gods and goddesses
30
00:01:31.680 --> 00:01:34.680
of wind. Meanwhile, construction work
31
00:01:34.680 --> 00:01:37.360
continues on the Dragonfly spacecraft itself,
32
00:01:37.360 --> 00:01:39.360
which is now being assembled in a clean room
33
00:01:39.360 --> 00:01:41.160
at the Johns Hopkins Applied Physics
34
00:01:41.160 --> 00:01:43.960
Laboratory in Lorell, Maryland. Cables are
35
00:01:43.960 --> 00:01:45.800
being carefully installed in the flight
36
00:01:45.800 --> 00:01:47.880
fuselage, providing the Titan bound
37
00:01:47.880 --> 00:01:49.920
rotorcraft with its central nervous system
38
00:01:50.480 --> 00:01:52.320
now. Ah. Collectively, these bundles of
39
00:01:52.320 --> 00:01:54.600
wires, cables and connectors make up the
40
00:01:54.600 --> 00:01:56.800
spacecraft's electrical harness, which will
41
00:01:56.800 --> 00:01:59.320
transmit power and data between the lander's
42
00:01:59.320 --> 00:02:01.720
computers, actuators, sensors, scientific
43
00:02:01.720 --> 00:02:04.380
instruments and battery. Dragonfly
44
00:02:04.380 --> 00:02:06.980
lander harness lead Jacqui Perry says it's a
45
00:02:06.980 --> 00:02:08.700
key milestone for the engineers and
46
00:02:08.700 --> 00:02:11.620
technicians building the vehicle. The wire is
47
00:02:11.620 --> 00:02:13.740
silver coated copper, insulated with a heat
48
00:02:13.740 --> 00:02:15.740
resistant durable polymer coating and then
49
00:02:15.740 --> 00:02:17.900
wrapped in aluminium, which is then attached
50
00:02:17.900 --> 00:02:19.539
at plastic and metal connectors.
51
00:02:19.940 --> 00:02:22.220
Perry says the wiring harness could only be
52
00:02:22.220 --> 00:02:24.220
installed once the flight structure was
53
00:02:24.220 --> 00:02:26.140
delivered and the remote interface units and
54
00:02:26.140 --> 00:02:28.660
temperature sensors were installed. The
55
00:02:28.660 --> 00:02:30.460
harness is typically one of the first
56
00:02:30.460 --> 00:02:32.420
components delivered to a spacecraft.
57
00:02:33.540 --> 00:02:35.700
Dragonfly passed its critical design review
58
00:02:35.700 --> 00:02:38.620
in 2022. Fabrication of the vehicle began
59
00:02:38.620 --> 00:02:41.380
in late 2024 and finished last year.
60
00:02:42.100 --> 00:02:44.860
Dragonfly is slated for launch in 2028 and
61
00:02:44.860 --> 00:02:47.780
will reach the Saturnian moon in late 2034.
62
00:02:48.579 --> 00:02:50.980
Dragonfly's operating environment on Titan
63
00:02:50.980 --> 00:02:53.900
poses some unique challenges because of the
64
00:02:53.900 --> 00:02:56.260
rotorcraft's thermos bottle design. Insulated
65
00:02:56.260 --> 00:02:58.500
to retain heat from its nuclear power source
66
00:02:58.500 --> 00:03:01.100
so it can stay warm in Titan's extremely cold
67
00:03:01.100 --> 00:03:03.100
conditions, the harness had been designed to
68
00:03:03.100 --> 00:03:05.800
route under a lay foam insulation on the
69
00:03:05.800 --> 00:03:07.640
outside of the lander and accommodate the
70
00:03:07.640 --> 00:03:09.920
circulation of warm air through the inside.
71
00:03:10.320 --> 00:03:12.360
Perry says the rotorcraft's high power
72
00:03:12.360 --> 00:03:14.960
demands require both 4 and 8Ah gauge
73
00:03:14.960 --> 00:03:16.920
wire, yet the harness still had to be
74
00:03:16.920 --> 00:03:18.960
flexible enough to weave through the packed
75
00:03:18.960 --> 00:03:21.080
interior, which includes the flight systems
76
00:03:21.080 --> 00:03:24.000
and instrument boxes as well as the 136
77
00:03:24.000 --> 00:03:26.800
kilogramme battery. Dragonfly
78
00:03:26.800 --> 00:03:29.360
will investigate Titan's prebiotic chemistry
79
00:03:29.360 --> 00:03:32.230
and assess the moon's habitability. It's not
80
00:03:32.230 --> 00:03:34.910
primarily a life detection mission, but aims
81
00:03:34.910 --> 00:03:36.990
to study how far organic chemistry has
82
00:03:36.990 --> 00:03:39.590
progressed in an environment rich in carbon
83
00:03:39.590 --> 00:03:41.830
compounds, which includes possible past
84
00:03:41.910 --> 00:03:44.830
mixing of liquid water and organics. The
85
00:03:44.830 --> 00:03:47.590
car sized 875 kilogramme lander
86
00:03:47.590 --> 00:03:50.350
features twin quadrotor engines powered by a
87
00:03:50.350 --> 00:03:52.590
radioisotope thermoelectric generator
88
00:03:52.590 --> 00:03:54.910
providing electricity and heat. The
89
00:03:54.910 --> 00:03:57.670
3.85 metre long vehicle is designed to
90
00:03:57.670 --> 00:04:00.310
fly several kilometres between landing sites,
91
00:04:00.310 --> 00:04:02.390
allowing it to sample diverse locations.
92
00:04:03.250 --> 00:04:05.490
Mission managers expect to cover over 115
93
00:04:05.490 --> 00:04:08.330
kilometres during Dragonfly's 3.3 year
94
00:04:08.330 --> 00:04:10.410
primary mission, exploring a range of
95
00:04:10.410 --> 00:04:12.970
different environments from organic dunes to
96
00:04:12.970 --> 00:04:15.170
deposits associated with an impact crater.
97
00:04:15.330 --> 00:04:17.010
Silk Crater, which we mentioned earlier,
98
00:04:17.090 --> 00:04:19.250
where liquid water and complex organic
99
00:04:19.250 --> 00:04:21.290
materials, which are key to life as we know
100
00:04:21.290 --> 00:04:24.010
it, once existed together. Scientific
101
00:04:24.010 --> 00:04:26.330
analysis indicates the impact that formed
102
00:04:26.330 --> 00:04:28.730
Silk Crater melted the icy bedrock,
103
00:04:28.730 --> 00:04:30.970
potentially creating a large temporary pool
104
00:04:30.970 --> 00:04:32.930
of water that could have remained liquid for
105
00:04:32.930 --> 00:04:35.110
hundreds of thousands of years under an
106
00:04:35.110 --> 00:04:37.510
insulating ice layer like winter ponds on the
107
00:04:37.510 --> 00:04:37.870
Earth.
108
00:04:38.670 --> 00:04:40.830
This report from NASA TV
109
00:04:41.550 --> 00:04:42.550
Saturn's largest
110
00:04:42.550 --> 00:04:45.350
NASA TV: moon, Titan, has a thick atmosphere and a
111
00:04:45.350 --> 00:04:48.030
frozen surface rich in organic molecules.
112
00:04:48.590 --> 00:04:50.990
In 2034, a NASA mission called
113
00:04:50.990 --> 00:04:53.790
Dragonfly will arrive at Titan and study its
114
00:04:53.790 --> 00:04:56.150
chemical makeup. Dragonfly is a
115
00:04:56.150 --> 00:04:59.110
rotorcraft designed to visit multiple sites
116
00:04:59.110 --> 00:05:00.990
across the moon's varied terrain.
117
00:05:03.290 --> 00:05:05.730
At each new landing site on Titan's surface,
118
00:05:05.730 --> 00:05:08.530
Dragonfly uses a pulsed neutron generator
119
00:05:08.530 --> 00:05:11.410
and onboard gamma ray sensor to detect key
120
00:05:11.410 --> 00:05:13.850
elements such as carbon and hydrogen in
121
00:05:13.850 --> 00:05:16.570
organic materials or oxygen in water
122
00:05:16.570 --> 00:05:19.410
ice. Dragonfly determines if there are
123
00:05:19.410 --> 00:05:21.850
well defined layers of these materials just
124
00:05:21.850 --> 00:05:24.650
below the lander for a closer inspection.
125
00:05:24.810 --> 00:05:27.380
Dragonfly uses its drill to generate
126
00:05:27.380 --> 00:05:30.180
tailings from Titan's hard frozen surface.
127
00:05:30.980 --> 00:05:33.380
These surface samples can then be ingested
128
00:05:33.380 --> 00:05:35.380
through the pneumatic system carried with
129
00:05:35.380 --> 00:05:38.180
Titan air into the chilled sample lines into
130
00:05:38.180 --> 00:05:41.180
the sample collection carousel. One of the
131
00:05:41.180 --> 00:05:43.900
carousel sample cups is placed in a pneumatic
132
00:05:43.900 --> 00:05:46.420
port. The cup captures the surface
133
00:05:46.420 --> 00:05:48.620
material from the cold air stream and
134
00:05:48.620 --> 00:05:50.700
transfers it to the chemical laboratory for
135
00:05:50.700 --> 00:05:53.420
measurement. Pulses from a laser
136
00:05:53.420 --> 00:05:55.500
release large organic molecules from the
137
00:05:55.500 --> 00:05:57.720
surface sample for analysis in the Mass
138
00:05:57.720 --> 00:06:00.640
spectrometer. The mass spectrometer sorts
139
00:06:00.640 --> 00:06:03.360
molecules by mass and measures diagnostic
140
00:06:03.360 --> 00:06:05.720
fragments that tell Dragonfly the kinds of
141
00:06:05.720 --> 00:06:07.560
chemical components that are present in the
142
00:06:07.560 --> 00:06:09.800
surface and whether there are molecules of
143
00:06:09.800 --> 00:06:12.320
prebiotic interest. For those
144
00:06:12.320 --> 00:06:15.240
potential prebiotic samples, a new cup is
145
00:06:15.240 --> 00:06:17.440
placed into an oven and heated to release
146
00:06:17.440 --> 00:06:19.960
molecules into a gas chromatograph, where
147
00:06:19.960 --> 00:06:21.960
they are sorted for size and type before
148
00:06:21.960 --> 00:06:24.330
entering the mass spectrometer. This
149
00:06:24.330 --> 00:06:26.810
advanced separation of organic components
150
00:06:26.890 --> 00:06:29.450
includes isolating molecules with the same
151
00:06:29.450 --> 00:06:32.010
formula but different chiral arrangements, or
152
00:06:32.010 --> 00:06:32.730
handedness.
153
00:06:33.210 --> 00:06:35.410
Having a preference for one handedness over
154
00:06:35.410 --> 00:06:38.090
another is a key biosignature for life on
155
00:06:38.090 --> 00:06:40.610
Earth. When the chemical analysis is
156
00:06:40.610 --> 00:06:42.890
complete, Dragonfly may choose to take
157
00:06:42.890 --> 00:06:45.850
another surface sample or find a new location
158
00:06:45.850 --> 00:06:47.370
on Titan to investigate.
159
00:06:47.450 --> 00:06:50.110
Stuart Gary: This whole mission's quite a challenge. Titan
160
00:06:50.110 --> 00:06:52.750
is unique in our solar system. It has a
161
00:06:52.750 --> 00:06:55.430
diameter of 5,150 kilometres,
162
00:06:55.510 --> 00:06:58.230
making it Saturn's largest moon and 50%
163
00:06:58.230 --> 00:07:00.350
bigger than the Earth's moon. In fact, it's
164
00:07:00.350 --> 00:07:03.030
larger than the planet Mercury. It's also the
165
00:07:03.030 --> 00:07:05.509
only moon with a substantial atmosphere and
166
00:07:05.509 --> 00:07:07.670
the only world other than Earth where clouds
167
00:07:07.670 --> 00:07:10.030
release rain that form streams and rivers,
168
00:07:10.030 --> 00:07:12.150
which then flow into lakes and seas.
169
00:07:12.790 --> 00:07:15.390
But Titan is so cold, the water there is
170
00:07:15.390 --> 00:07:18.270
normally frozen solid, forming bedrock. And
171
00:07:18.270 --> 00:07:20.990
instead of water, the liquid rain on Titan is
172
00:07:20.990 --> 00:07:23.710
made up of methane and ethane hydrocarbons.
173
00:07:24.030 --> 00:07:27.030
But scientists describe Titan as analogous to
174
00:07:27.030 --> 00:07:29.630
the early Earth. That's because it preserves
175
00:07:29.630 --> 00:07:31.150
a set of environmental and chemical
176
00:07:31.150 --> 00:07:32.870
conditions which are thought to have existed
177
00:07:32.870 --> 00:07:35.190
on our planet billions of years ago, before
178
00:07:35.190 --> 00:07:37.870
life arose and before free oxygen
179
00:07:37.870 --> 00:07:40.590
accumulated in our atmosphere. It
180
00:07:40.590 --> 00:07:42.950
therefore serves as a natural laboratory for
181
00:07:42.950 --> 00:07:45.430
studying prebiotic chemistry on a planetary
182
00:07:45.430 --> 00:07:48.340
scale. Scientists think its complex organic
183
00:07:48.340 --> 00:07:50.220
chemistry, methane cycle and possible
184
00:07:50.220 --> 00:07:52.540
environments could support exotic forms of
185
00:07:52.540 --> 00:07:54.860
life, or at least prebiotic chemistry.
186
00:07:55.180 --> 00:07:57.500
It's also considered one of the more feasible
187
00:07:57.500 --> 00:07:59.660
destinations for future human exploration
188
00:07:59.660 --> 00:08:02.059
among the outer solar system bodies due to
189
00:08:02.059 --> 00:08:04.380
its thick atmosphere for radiation shielding
190
00:08:04.380 --> 00:08:05.740
and available resources.
191
00:08:06.940 --> 00:08:09.500
Titan was extensively studied by the Cassini
192
00:08:09.500 --> 00:08:11.700
Huygens mission, which orbited the Saturnian
193
00:08:11.700 --> 00:08:14.300
system between 2004 and 2017.
194
00:08:15.290 --> 00:08:17.170
The Huygens Lander was deployed from the
195
00:08:17.170 --> 00:08:19.810
Cassini spacecraft down to Titan's surface on
196
00:08:19.810 --> 00:08:22.610
December 25, 2004, landing
197
00:08:22.610 --> 00:08:25.170
on January 14, 2005, near the
198
00:08:25.170 --> 00:08:27.570
Ediri region, the boundary between brighter
199
00:08:27.570 --> 00:08:30.410
highlands and darker plains. The lander
200
00:08:30.410 --> 00:08:33.130
spent about 90 minutes on the surface taking
201
00:08:33.130 --> 00:08:35.170
readings and measurements before the
202
00:08:35.170 --> 00:08:37.650
batteries ran out. Huygens was able to
203
00:08:37.650 --> 00:08:39.730
confirm that Titan has a thick, nitrogen
204
00:08:39.730 --> 00:08:42.170
dominated atmosphere with methane and a range
205
00:08:42.170 --> 00:08:44.570
of aerosols and complex organic chemistry.
206
00:08:45.250 --> 00:08:47.970
It measured strong High altitude zonal winds
207
00:08:47.970 --> 00:08:50.250
on its way down and weaker winds near the
208
00:08:50.250 --> 00:08:52.730
surface. It also measured a surface
209
00:08:52.730 --> 00:08:55.730
temperature of -179 degrees Celsius
210
00:08:56.210 --> 00:08:59.010
and a surface atmospheric pressure about 50%
211
00:08:59.090 --> 00:09:00.850
higher than sea level here on Earth.
212
00:09:01.570 --> 00:09:04.210
Intriguingly, it found the ground on Titan
213
00:09:04.210 --> 00:09:06.490
was soft and damp, with the consistency of
214
00:09:06.490 --> 00:09:08.850
wet sand, clay or lightly packed snow.
215
00:09:09.330 --> 00:09:11.610
Images showed the surface of Titan was
216
00:09:11.610 --> 00:09:13.810
littered with water ice, pebbles or cobbles a
217
00:09:13.810 --> 00:09:16.130
few centimetres across on an orange tinted
218
00:09:16.130 --> 00:09:18.910
organic rich plane. There was also evidence
219
00:09:18.910 --> 00:09:21.030
of past liquid flows near the landing site
220
00:09:21.030 --> 00:09:23.150
and possible methane release from the
221
00:09:23.150 --> 00:09:25.990
subsurface. Needless to say, as the
222
00:09:25.990 --> 00:09:28.270
Dragonfly mission progresses, we'll keep you
223
00:09:28.270 --> 00:09:31.150
informed. This is space
224
00:09:31.230 --> 00:09:31.630
time.
225
00:09:32.670 --> 00:09:35.190
Still to come, new clues about the Earth's
226
00:09:35.190 --> 00:09:37.950
Moon's ancient magnetic field. And we examine
227
00:09:37.950 --> 00:09:40.550
why galaxies in the early universe look so
228
00:09:40.550 --> 00:09:42.990
weird. All that and more still to come
229
00:09:43.370 --> 00:09:44.410
on space time.
230
00:09:53.450 --> 00:09:55.730
A new study claims that just like the present
231
00:09:55.730 --> 00:09:58.530
day Earth, our moon once had a geodynamo
232
00:09:58.530 --> 00:10:01.330
driven magnetic field. On Earth, the
233
00:10:01.330 --> 00:10:03.490
movement of liquid iron in the planet's outer
234
00:10:03.490 --> 00:10:05.930
core generates its global magnetic field.
235
00:10:06.410 --> 00:10:09.290
This so called geodynamo works on a similar
236
00:10:09.290 --> 00:10:11.530
principle to a dynamo on a bicycle, which
237
00:10:11.530 --> 00:10:13.690
converts mechanical motion into electrical
238
00:10:13.690 --> 00:10:16.520
energy. But unlike today's Earth, the Moon
239
00:10:16.520 --> 00:10:18.960
no longer has a core generated magnetic
240
00:10:18.960 --> 00:10:21.240
field. One of the study's authors, Anna
241
00:10:21.240 --> 00:10:23.680
Mittelholz from EDH Zurich, says there's a
242
00:10:23.680 --> 00:10:25.840
heated ongoing debate about whether the Moon
243
00:10:25.840 --> 00:10:28.000
also operated a dynamo in the past.
244
00:10:28.560 --> 00:10:30.800
That's because analysis of rock samples
245
00:10:30.800 --> 00:10:32.280
brought back to Earth by the Apollo
246
00:10:32.280 --> 00:10:35.040
astronauts are somewhat contradictory. Some
247
00:10:35.040 --> 00:10:36.640
researchers assume there was a strong
248
00:10:36.640 --> 00:10:38.600
magnetic field that existed over a long
249
00:10:38.600 --> 00:10:41.520
period of time, somewhere around 4.25 to
250
00:10:41.520 --> 00:10:44.260
3.5 billion years ago, while others find
251
00:10:44.260 --> 00:10:47.140
absolutely no evidence of this. You see, in
252
00:10:47.140 --> 00:10:48.860
addition to the dynamo theory, there's a
253
00:10:48.860 --> 00:10:50.580
second possible explanation for the
254
00:10:50.580 --> 00:10:53.220
magnetised lunar rocks, namely impacts from
255
00:10:53.220 --> 00:10:55.300
massive meteorites or asteroids, which could
256
00:10:55.300 --> 00:10:57.180
have triggered a, uh, magnetization process
257
00:10:57.180 --> 00:10:59.660
on the Moon. But the new research
258
00:10:59.900 --> 00:11:02.300
reported in the journal Science Advances now
259
00:11:02.300 --> 00:11:05.140
supports the dynamo theory. Mittelholz and
260
00:11:05.140 --> 00:11:07.380
colleagues say that around 4.2 billion years
261
00:11:07.380 --> 00:11:09.660
ago, the Moon did indeed possess an
262
00:11:09.660 --> 00:11:12.550
internally generated magnetic field. Uh, now
263
00:11:12.550 --> 00:11:15.030
this claim isn't based on rock samples, but
264
00:11:15.030 --> 00:11:17.510
on data collected by probes in lunar orbit,
265
00:11:17.510 --> 00:11:19.430
including gravity measurements by NASA's
266
00:11:19.430 --> 00:11:21.710
GRAIL probes and magnetic field models.
267
00:11:21.710 --> 00:11:23.510
Drawing on orbital measurements from the
268
00:11:23.510 --> 00:11:25.710
Lunar Prospector, UH and Kagua missions
269
00:11:26.270 --> 00:11:28.230
to reach their conclusions, the authors
270
00:11:28.230 --> 00:11:30.550
examined the Dewa region on the lunar far
271
00:11:30.550 --> 00:11:32.430
side, which is never seen from Earth.
272
00:11:32.910 --> 00:11:35.150
Mittelholz says Dewa has one of the strongest
273
00:11:35.150 --> 00:11:37.230
magnetic field anomalies on the far side of
274
00:11:37.230 --> 00:11:39.390
the Moon. And a distinct gravity anomaly
275
00:11:39.390 --> 00:11:42.270
coincides spatially there as well as that
276
00:11:42.270 --> 00:11:44.110
means this region contains rocks that were
277
00:11:44.110 --> 00:11:46.070
more strongly magnetised, while at the same
278
00:11:46.070 --> 00:11:49.070
time denser than elsewhere. In most cases,
279
00:11:49.150 --> 00:11:51.190
the origin of magnetic anomalies measured
280
00:11:51.190 --> 00:11:54.150
from lunar orbits are known. But the gravity
281
00:11:54.150 --> 00:11:56.630
data gives scientists an insight into the
282
00:11:56.630 --> 00:11:58.830
density and consequently the type of material
283
00:11:58.830 --> 00:12:01.590
beneath the surface. Mittelholz says where
284
00:12:01.590 --> 00:12:03.230
the magnetic field and gravity signals
285
00:12:03.230 --> 00:12:05.950
coincide, it is possible to combine the two
286
00:12:05.950 --> 00:12:07.910
and attribute the anomaly to a specific
287
00:12:07.910 --> 00:12:10.730
geological feature. And that's where Dewar
288
00:12:10.730 --> 00:12:13.250
comes in. It allowed the authors to create an
289
00:12:13.250 --> 00:12:15.930
accurate model of the subsurface by jointly
290
00:12:15.930 --> 00:12:18.120
processing gravity and magnetic field data.
291
00:12:18.120 --> 00:12:20.690
Uh, this data shows the area beneath
292
00:12:20.690 --> 00:12:23.010
Dewar's surface contains a rock body
293
00:12:23.010 --> 00:12:25.290
approximately 60 kilometres wide, extending
294
00:12:25.290 --> 00:12:27.290
to a depth of around nine kilometres.
295
00:12:27.850 --> 00:12:30.250
It's far denser than the surrounding crust
296
00:12:30.250 --> 00:12:33.250
and it's strongly magnetised. Combined with
297
00:12:33.250 --> 00:12:35.130
a surface geochemistry and an arch
298
00:12:35.130 --> 00:12:37.050
topography, the authors conclude that it
299
00:12:37.050 --> 00:12:39.290
solidified magma that's risen from deep
300
00:12:39.290 --> 00:12:41.990
below, part of a buried volcanic complex.
301
00:12:42.550 --> 00:12:45.190
The age of the structure, 4.2 billion years,
302
00:12:45.190 --> 00:12:47.270
was determined from various deposits of
303
00:12:47.270 --> 00:12:49.270
impact material on the lunar surface.
304
00:12:49.830 --> 00:12:51.950
Betelholz says because they know how much
305
00:12:51.950 --> 00:12:54.190
iron is present in such a rocky body, they
306
00:12:54.190 --> 00:12:55.790
can estimate the minimum strength the
307
00:12:55.790 --> 00:12:57.790
magnetic field must have had as the magma
308
00:12:57.790 --> 00:13:00.590
slowly cooled. It shows that at the time, the
309
00:13:00.590 --> 00:13:02.550
magnetic field on the Moon was likely more
310
00:13:02.550 --> 00:13:05.430
than 10 micro Tesla. Now, by comparison,
311
00:13:05.430 --> 00:13:07.390
here on Earth today, the planet's magnetic
312
00:13:07.390 --> 00:13:10.350
field stands at around 50 micro Tesla. The
313
00:13:10.350 --> 00:13:12.230
authors have ruled out the possibility of an
314
00:13:12.230 --> 00:13:14.230
impact crater creating the magnetic field.
315
00:13:14.230 --> 00:13:16.550
Because there's no matching cratering signs,
316
00:13:17.030 --> 00:13:19.670
it's still unclear how the small lunar core
317
00:13:19.670 --> 00:13:21.670
could have generated such a strong magnetic
318
00:13:21.670 --> 00:13:24.270
field. So the authors admit the existence of
319
00:13:24.270 --> 00:13:26.870
an early lunar geodynamo isn't yet fully
320
00:13:26.870 --> 00:13:29.550
resolved. This study is also
321
00:13:29.550 --> 00:13:31.350
providing fresh insights into another
322
00:13:31.350 --> 00:13:33.670
puzzling phenomena lunar swirls.
323
00:13:34.150 --> 00:13:36.590
These bright, curved and striped patterns on
324
00:13:36.590 --> 00:13:38.990
the Moon's surface stand out clearly against
325
00:13:38.990 --> 00:13:41.860
their darker surroundings. Wherever such
326
00:13:41.860 --> 00:13:44.340
swirl patterns appear, scientists always find
327
00:13:44.340 --> 00:13:47.300
magnetic anomalies. And there is a lunar
328
00:13:47.300 --> 00:13:49.340
swirl on the surface of the Dewar region,
329
00:13:49.420 --> 00:13:52.260
right above the observed anomaly. The origin
330
00:13:52.260 --> 00:13:55.020
of the swirls remains a matter of debate. One
331
00:13:55.020 --> 00:13:57.260
possible explanation is that the swirls only
332
00:13:57.340 --> 00:13:59.060
form where the magnetic field runs
333
00:13:59.060 --> 00:14:01.220
horizontally at the surface. As is the case
334
00:14:01.220 --> 00:14:03.980
with the Dewar swirl, the horizontal field
335
00:14:03.980 --> 00:14:06.260
deflects the solar wind, thereby protecting
336
00:14:06.260 --> 00:14:08.470
the surface from weathering. And as a result,
337
00:14:08.550 --> 00:14:10.390
the area remains brighter than its
338
00:14:10.390 --> 00:14:12.990
surroundings, Mittelholz says That would be
339
00:14:12.990 --> 00:14:15.270
important information for future astronauts,
340
00:14:15.270 --> 00:14:17.070
as magnetic field lines could offer
341
00:14:17.070 --> 00:14:19.150
protection from the solar wind, and the
342
00:14:19.150 --> 00:14:21.630
swirls would indicate the locations of that
343
00:14:21.630 --> 00:14:24.310
shielding. This is space time.
344
00:14:25.030 --> 00:14:27.230
Still to come. Why galaxies in the early
345
00:14:27.230 --> 00:14:29.390
universe look so weird? And later in the
346
00:14:29.390 --> 00:14:31.670
Science report, discovery of a common
347
00:14:31.670 --> 00:14:33.990
chemical in plastics, which has been linked
348
00:14:33.990 --> 00:14:36.550
to the development of ADHD and autism.
349
00:14:37.120 --> 00:14:39.440
All that and more still to come on, uh, space
350
00:14:39.520 --> 00:14:39.920
time.
351
00:14:55.520 --> 00:14:57.960
A new study suggests that the first galaxies
352
00:14:57.960 --> 00:14:59.760
in the universe looked a bit weird because
353
00:14:59.760 --> 00:15:02.320
their stars generated weaker stellar winds
354
00:15:02.610 --> 00:15:05.170
compared to those we see today. The new
355
00:15:05.170 --> 00:15:06.810
research could reshape science's
356
00:15:06.810 --> 00:15:09.050
understanding of how galaxies formed in the
357
00:15:09.050 --> 00:15:12.010
early universe. The findings reported in the
358
00:15:12.010 --> 00:15:14.090
Astrophysical Journal are showing that the
359
00:15:14.090 --> 00:15:16.130
more astronomers learn about the universe's
360
00:15:16.130 --> 00:15:18.370
earliest galaxies, the stranger they seem.
361
00:15:19.010 --> 00:15:21.570
The new observations are based on a survey by
362
00:15:21.570 --> 00:15:23.730
NASA's Hubble Space Telescope, which looked
363
00:15:23.730 --> 00:15:26.650
at 29 massive stars located in extremely
364
00:15:26.650 --> 00:15:28.810
metal pore galaxies, finding they all had
365
00:15:28.810 --> 00:15:30.930
unexpectedly weak stellar winds.
366
00:15:31.820 --> 00:15:34.140
Astronomers use the term metals to describe
367
00:15:34.140 --> 00:15:36.180
all elements heavier than hydrogen and
368
00:15:36.180 --> 00:15:39.060
helium. The treasury of Extremely
369
00:15:39.060 --> 00:15:41.980
Metal Poor O Stars, or TEMPOS survey, uses
370
00:15:41.980 --> 00:15:44.340
ultraviolet observations from Hubble's Cosmic
371
00:15:44.340 --> 00:15:47.100
Origin Spectrograph to study massive stars in
372
00:15:47.100 --> 00:15:49.180
nearby galaxies, which are the best available
373
00:15:49.180 --> 00:15:51.340
analogues for stars in the early universe.
374
00:15:51.660 --> 00:15:54.020
The TEMPOS dataset could help astronomers
375
00:15:54.020 --> 00:15:56.300
build better models of massive stars in order
376
00:15:56.300 --> 00:15:58.420
to understand how they shaped galaxies when
377
00:15:58.420 --> 00:16:01.270
the universe was still very young. And these
378
00:16:01.270 --> 00:16:03.110
models would be essential for interpreting
379
00:16:03.110 --> 00:16:05.350
the observations of early galaxies now coming
380
00:16:05.350 --> 00:16:07.310
to light. Thanks to NASA's Webb Space

Telescope studies. Lead author
382
00:16:10.110 --> 00:16:12.430
Grace Telford from the University of Utah
383
00:16:12.430 --> 00:16:14.790
says Webb is opening up a whole new slew of
384
00:16:14.790 --> 00:16:16.990
questions about the evolution of these early
385
00:16:16.990 --> 00:16:19.710
weird galaxies. Tilford says the
386
00:16:19.710 --> 00:16:22.110
scientific motivation behind TEMPOS is to
387
00:16:22.110 --> 00:16:23.990
help understand what's going on in these
388
00:16:23.990 --> 00:16:26.910
early galaxies. Massive stars, those with
389
00:16:26.910 --> 00:16:28.710
masses more than 10 times greater than our
390
00:16:28.710 --> 00:16:31.510
sun, are rare but powerful engines of cosm.
391
00:16:32.730 --> 00:16:35.290
They produce intense radiation. They shed
392
00:16:35.290 --> 00:16:37.370
materials through powerful stellar winds,
393
00:16:37.370 --> 00:16:40.170
they burn very hot, very bright, and very
394
00:16:40.250 --> 00:16:43.170
fast, and end their short lives as supernova
395
00:16:43.170 --> 00:16:45.650
explosions, blasting vast amounts of energy
396
00:16:45.650 --> 00:16:47.770
and material into the surrounding space.
397
00:16:48.490 --> 00:16:50.450
Consequently, they govern the evolution of
398
00:16:50.450 --> 00:16:52.770
the host galaxies by heating and essentially
399
00:16:52.770 --> 00:16:54.850
regulating the gas that's then available to
400
00:16:54.850 --> 00:16:57.370
cool and form new generations of stars.
401
00:16:58.180 --> 00:16:59.900
The thing is, the universe's earliest
402
00:16:59.900 --> 00:17:02.060
galaxies contained fewer, uh, heavy elements
403
00:17:02.060 --> 00:17:04.300
compared to galaxies we see today. Like our
404
00:17:04.300 --> 00:17:07.140
own Milky Way, for example, the massive stars
405
00:17:07.140 --> 00:17:09.340
forming in those early galaxies also likely
406
00:17:09.340 --> 00:17:11.140
had very different physical properties.
407
00:17:11.620 --> 00:17:14.580
Tilford says massive stars at low metallicity
408
00:17:14.580 --> 00:17:16.300
are especially important for building
409
00:17:16.300 --> 00:17:19.220
accurate models of early galaxies. That's
410
00:17:19.220 --> 00:17:21.260
because high metallicity stars like those in
411
00:17:21.260 --> 00:17:23.380
the Milky Way behave very differently
412
00:17:23.380 --> 00:17:25.340
compared to the metal pore stars of the early
413
00:17:25.340 --> 00:17:28.050
cosmos. So the Tempos survey
414
00:17:28.050 --> 00:17:30.570
specifically looked to nearby low mass dwarf
415
00:17:30.570 --> 00:17:32.650
galaxies, which have low metallicities by
416
00:17:32.650 --> 00:17:34.690
nature and uh, are therefore more typical of
417
00:17:34.690 --> 00:17:36.610
the sorts of galaxies you'd see near the dawn
418
00:17:36.610 --> 00:17:39.530
of the universe. It surveyed 29
419
00:17:39.530 --> 00:17:42.489
massive stars across six local dwarf galaxies
420
00:17:42.489 --> 00:17:45.130
that all have metallicities below 1/5 that of
421
00:17:45.130 --> 00:17:47.690
our Sun. They looked across the ultraviolet
422
00:17:47.690 --> 00:17:49.490
spectrum because it contains detailed
423
00:17:49.490 --> 00:17:51.090
signatures of elements in the stars
424
00:17:51.090 --> 00:17:53.050
atmospheres which reveal information about
425
00:17:53.050 --> 00:17:54.780
the stellar winds which which continually
426
00:17:54.780 --> 00:17:57.260
blur material away from those star surfaces.
427
00:17:58.700 --> 00:18:01.260
Individual massive stars in these galaxies
428
00:18:01.260 --> 00:18:03.500
outside the Milky Way are very faint,
429
00:18:03.580 --> 00:18:05.660
requiring many hours of observational time
430
00:18:05.660 --> 00:18:07.420
with some of the most powerful telescopes in
431
00:18:07.420 --> 00:18:10.420
the world. Telford says the 29 stars in the
432
00:18:10.420 --> 00:18:13.180
survey sample each took up to 35 hours of
433
00:18:13.180 --> 00:18:15.020
Hubble telescope time to observe.
434
00:18:16.140 --> 00:18:18.740
Massive stars lose material through stellar
435
00:18:18.740 --> 00:18:20.800
winds. And the strength of the winds the
436
00:18:20.950 --> 00:18:23.870
depends on metallicity. Metal ions couple the
437
00:18:23.870 --> 00:18:26.230
star's radiation to the surrounding material.
438
00:18:26.710 --> 00:18:29.510
So astronomers expect lower metallicity stars
439
00:18:29.510 --> 00:18:31.950
to drive weaker stellar winds and lose less
440
00:18:31.950 --> 00:18:34.630
mass over their lifetimes. And the TEMPOS
441
00:18:34.630 --> 00:18:36.790
observations showed the expected overall
442
00:18:36.790 --> 00:18:39.750
trend. As metallicity decreases, the maximum
443
00:18:39.750 --> 00:18:41.910
speed of the stellar wind also decreases.
444
00:18:42.550 --> 00:18:44.790
And at the lowest metallicities, stars with
445
00:18:44.790 --> 00:18:47.270
metallicity below about 10% that of our sun,
446
00:18:47.270 --> 00:18:49.310
the wind speeds decline much more sharply
447
00:18:49.310 --> 00:18:51.430
than expected compared to the rates observed
448
00:18:51.430 --> 00:18:54.410
at higher metall. Tolford says there's a
449
00:18:54.410 --> 00:18:56.770
sort of smooth trend. And then suddenly for
450
00:18:56.770 --> 00:18:58.850
the lowest metallicity stars, the wind drops
451
00:18:58.850 --> 00:19:01.810
off very sharply. If extremely
452
00:19:01.810 --> 00:19:04.050
metal poor stars lose less mass through
453
00:19:04.050 --> 00:19:06.410
weaker winds, they may retain more of their
454
00:19:06.410 --> 00:19:08.730
original mass for longer, affecting how they
455
00:19:08.730 --> 00:19:11.490
evolve, how they die, and how they shape
456
00:19:11.490 --> 00:19:14.330
their host galaxies. And because massive
457
00:19:14.330 --> 00:19:16.530
stars influence the gas around them, changes
458
00:19:16.530 --> 00:19:18.650
in their evolution could ripple outwards,
459
00:19:18.650 --> 00:19:20.780
affecting their host galaxies as well. As
460
00:19:21.890 --> 00:19:24.210
iron may be the most important element in
461
00:19:24.210 --> 00:19:27.010
massive star physics, it plays a key
462
00:19:27.010 --> 00:19:29.530
role in launching stellar winds, determining
463
00:19:29.530 --> 00:19:31.810
how a star evolves through its lifetime, and
464
00:19:31.810 --> 00:19:34.410
triggering the supernova explosions that ends
465
00:19:34.410 --> 00:19:37.089
a star's existence. Yet despite its
466
00:19:37.089 --> 00:19:39.730
crucial role, iron abundance is notoriously
467
00:19:39.730 --> 00:19:41.410
difficult to measure in metal poor
468
00:19:41.410 --> 00:19:44.410
environments. So instead, astronomers
469
00:19:44.410 --> 00:19:46.970
often use oxygen as a surrogate in a galaxy's
470
00:19:46.970 --> 00:19:49.150
gas in order to estimate its metallicity.
471
00:19:49.150 --> 00:19:51.750
Because oxygen ions produce easily observed
472
00:19:51.750 --> 00:19:53.910
emission lines when illuminated by massive
473
00:19:53.910 --> 00:19:56.670
stars, they assume the iron abundance
474
00:19:56.750 --> 00:19:59.710
matches the oxygen. But it's not guaranteed
475
00:19:59.710 --> 00:20:01.790
that iron and oxygen would track each other
476
00:20:01.790 --> 00:20:04.630
perfectly. So the Tempos team measured the
477
00:20:04.630 --> 00:20:06.750
strengths of hard to detect iron absorption
478
00:20:06.750 --> 00:20:08.750
features in the ultraviolet spectra.
479
00:20:09.230 --> 00:20:11.190
Basically, they assessed how much light the
480
00:20:11.190 --> 00:20:13.030
iron was removing from what would otherwise
481
00:20:13.030 --> 00:20:15.550
have been a flat level of ultraviolet light.
482
00:20:16.160 --> 00:20:18.640
They found that massive stars in more oxygen
483
00:20:18.640 --> 00:20:20.880
rich, high metallicity galaxies tend to have
484
00:20:20.880 --> 00:20:22.600
much stronger ion absorption in their
485
00:20:22.600 --> 00:20:25.200
ultraviolet spectra than stars in oxygen poor
486
00:20:25.200 --> 00:20:28.040
low metallicity galaxies. The variation in
487
00:20:28.040 --> 00:20:30.000
ion absorption strengths in the Tempos
488
00:20:30.000 --> 00:20:32.520
dataset suggests that these metal poor stars
489
00:20:32.520 --> 00:20:35.280
actually span a wide range of ion abundances.
490
00:20:36.480 --> 00:20:39.160
The work is just beginning. The authors are
491
00:20:39.160 --> 00:20:41.560
now combining the Hubble ultraviolet spectra
492
00:20:41.560 --> 00:20:43.680
with visible light observations from the Keck
493
00:20:43.680 --> 00:20:46.250
Observatory in Hawaii. Together, uh, these
494
00:20:46.250 --> 00:20:48.850
data sets will allow them to model the stars
495
00:20:48.850 --> 00:20:51.170
in greater detail and measure properties such
496
00:20:51.170 --> 00:20:53.530
as chemical abundances and wind driven mass
497
00:20:53.530 --> 00:20:55.530
loss rates. Information which could
498
00:20:55.530 --> 00:20:57.650
ultimately help astronomers interpret what
499
00:20:57.650 --> 00:20:59.290
the Webb Telescope is seeing in the very
500
00:20:59.290 --> 00:21:02.290
early universe. What Hubble sees
501
00:21:02.290 --> 00:21:04.050
in mostly visible light and into the
502
00:21:04.050 --> 00:21:06.490
ultraviolet, Webb can view in the infrared,
503
00:21:06.490 --> 00:21:08.170
where visible light from the very early
504
00:21:08.170 --> 00:21:10.930
universe is stretched into longer wavelengths
505
00:21:10.930 --> 00:21:13.730
by the actual physical expansion of spacetime
506
00:21:13.730 --> 00:21:16.150
itself, helping astronomers see the first
507
00:21:16.150 --> 00:21:18.430
generations of stars and galaxies in the
508
00:21:18.430 --> 00:21:21.270
universe. This report from the Space
509
00:21:21.270 --> 00:21:23.550
Telescope Science Institute, which operates
510
00:21:23.550 --> 00:21:26.190
both NASA's Hubble and Webb space telescopes.
511
00:21:26.430 --> 00:21:29.230
Nina Lanza: How did we get here? Big
512
00:21:29.230 --> 00:21:31.830
questions about who we are and how we got to
513
00:21:31.830 --> 00:21:34.270
be that way are at the core of our nature.
514
00:21:35.310 --> 00:21:37.760
We've developed technology to see, um,
515
00:21:37.760 --> 00:21:40.750
amazingly far across space and also time.
516
00:21:41.440 --> 00:21:43.920
Light moves through space just like we do,
517
00:21:44.080 --> 00:21:46.760
only much faster. It takes
518
00:21:46.760 --> 00:21:49.760
time to get somewhere. So viewing
519
00:21:49.760 --> 00:21:52.080
the light of distant stars and
520
00:21:52.160 --> 00:21:54.640
galaxies is like looking into the past.
521
00:21:54.960 --> 00:21:57.760
It took time for the light to reach us.
522
00:21:58.480 --> 00:22:00.960
Yet after all our years of exploring
523
00:22:01.280 --> 00:22:03.600
to better understand ourselves and our
524
00:22:03.600 --> 00:22:06.240
origins, There is still
525
00:22:06.400 --> 00:22:07.520
so much to know.
526
00:22:11.060 --> 00:22:13.940
Our story stretches back more than 13 billion
527
00:22:14.100 --> 00:22:16.540
years. Not long after the
528
00:22:16.540 --> 00:22:19.220
expansion of time and space first began
529
00:22:19.780 --> 00:22:22.660
at some m unknown time. The building blocks
530
00:22:22.660 --> 00:22:25.140
of life were forged in the heart of the first
531
00:22:25.140 --> 00:22:28.020
stars. But much of the early universe
532
00:22:28.020 --> 00:22:30.540
remains a mystery. There are
533
00:22:30.540 --> 00:22:32.940
theories about how gravity first brought
534
00:22:32.940 --> 00:22:35.800
stars, gas and dark matter together
535
00:22:35.880 --> 00:22:38.680
to form galaxies. But that
536
00:22:38.680 --> 00:22:41.080
time period has never been observed.
537
00:22:41.240 --> 00:22:43.560
Detecting light from the first galaxies to
538
00:22:43.560 --> 00:22:45.760
form has been a challenge for even the most
539
00:22:45.760 --> 00:22:48.720
powerful telescopes. As, uh, the light
540
00:22:48.720 --> 00:22:50.880
early galaxies emitted travelled through
541
00:22:50.880 --> 00:22:53.880
space, that space itself was
542
00:22:53.880 --> 00:22:56.640
expanding, Stretching the light
543
00:22:56.640 --> 00:22:59.300
to longer infrared wavelengths.
544
00:23:00.650 --> 00:23:03.210
Past telescopes have detected infrared light,
545
00:23:04.010 --> 00:23:06.730
but the faint light of the very
546
00:23:06.730 --> 00:23:09.210
first galaxies has remained out of reach
547
00:23:09.610 --> 00:23:12.450
until now. The James Webb Space
548
00:23:12.450 --> 00:23:15.450
Telescope is specially designed to detect
549
00:23:15.450 --> 00:23:18.250
the first galaxies. Webb's large
550
00:23:18.250 --> 00:23:21.010
mirror and sensitive instruments enable it to
551
00:23:21.010 --> 00:23:23.290
collect more infrared light than we've ever
552
00:23:23.290 --> 00:23:26.180
seen, allowing the first galaxies
553
00:23:26.500 --> 00:23:29.060
to emerge into view. With
554
00:23:29.140 --> 00:23:31.780
Webb, we can begin filling in some of the
555
00:23:31.780 --> 00:23:33.940
blank pages at the beginning of the
556
00:23:33.940 --> 00:23:36.540
universe's story. When did the first
557
00:23:36.540 --> 00:23:39.540
galaxies form? How massive were they? What
558
00:23:39.540 --> 00:23:42.500
types of stars and elements did they contain?
559
00:23:42.820 --> 00:23:45.380
The universe's story is our
560
00:23:45.460 --> 00:23:48.340
story. And with Webb, we can finally
561
00:23:48.340 --> 00:23:51.100
explore these questions as well, as well as
562
00:23:51.100 --> 00:23:53.500
uncover new ones we haven't even thought to
563
00:23:53.500 --> 00:23:53.860
ask.
564
00:23:54.660 --> 00:23:56.020
Stuart Gary: This is space, time.
565
00:24:11.380 --> 00:24:13.340
And time. Now to take another brief look at
566
00:24:13.340 --> 00:24:15.020
some of the other stories making news in
567
00:24:15.020 --> 00:24:16.900
Science this week with a Science report.
568
00:24:17.910 --> 00:24:20.190
A common chemical used to make plastics more
569
00:24:20.190 --> 00:24:21.950
flexible has now been linked to the
570
00:24:21.950 --> 00:24:24.550
development of autism and ADHD symptoms in
571
00:24:24.550 --> 00:24:27.350
early childhood. Previous studies had already
572
00:24:27.350 --> 00:24:30.350
shown that exposure to the plasticiser DHP
573
00:24:30.350 --> 00:24:33.270
in pregnancy was linked to autism and ADHD
574
00:24:33.270 --> 00:24:35.870
in young children. Now a report in the
575
00:24:35.870 --> 00:24:38.270
Medeneit Medical Journal looked at umbilical
576
00:24:38.270 --> 00:24:40.150
cord blood from Australian mothers and
577
00:24:40.150 --> 00:24:42.350
babies. Following up with more than 900
578
00:24:42.350 --> 00:24:45.330
children up to the age of four, they found
579
00:24:45.330 --> 00:24:48.090
that prenatal exposure to DHP may be
580
00:24:48.090 --> 00:24:50.450
influencing gene activity that can disturb
581
00:24:50.450 --> 00:24:52.570
brain development pathways linked to the
582
00:24:52.570 --> 00:24:54.770
later development of autism and or
583
00:24:54.770 --> 00:24:57.610
adhd. A uh,
584
00:24:57.650 --> 00:24:59.850
temporary slowing in the rate of Antarctic
585
00:24:59.850 --> 00:25:02.130
ice sheet mass loss in 2021 and
586
00:25:02.130 --> 00:25:04.730
2023 may have been caused by sea
587
00:25:04.730 --> 00:25:06.770
surface temperature rises thousands of
588
00:25:06.770 --> 00:25:09.730
kilometres away. The findings reported in
589
00:25:09.730 --> 00:25:11.810
the journal Nature are uh, based on data from
590
00:25:11.810 --> 00:25:13.930
both observational and modelling experiments
591
00:25:13.930 --> 00:25:15.850
which link the event to surface temperature
592
00:25:15.850 --> 00:25:18.070
anom families in the tropical warm pool
593
00:25:18.070 --> 00:25:20.030
between the western Pacific and eastern
594
00:25:20.030 --> 00:25:22.870
Indian Ocean. This area experienced
595
00:25:22.870 --> 00:25:25.790
unusually persistent warming between 2021
596
00:25:25.790 --> 00:25:28.310
and 2023 which led to a series of
597
00:25:28.310 --> 00:25:30.190
alternating high and low pressure weather
598
00:25:30.190 --> 00:25:32.190
patterns called the Rossby Wave train.
599
00:25:32.510 --> 00:25:34.190
According to the authors, this process
600
00:25:34.270 --> 00:25:36.310
eventually led to the formation of a high
601
00:25:36.310 --> 00:25:38.830
pressure anomaly over uh, Eastern Antarctica.
602
00:25:39.150 --> 00:25:41.150
This is thought to occur around once every
603
00:25:41.150 --> 00:25:43.430
decade, meaning that the pause in total ice
604
00:25:43.430 --> 00:25:45.870
sheet mass loss is likely only uh, temporary.
605
00:25:47.600 --> 00:25:49.120
Scientists have concluded that William
606
00:25:49.120 --> 00:25:51.360
Shakespeare's plays have turned out to be,
607
00:25:51.520 --> 00:25:53.720
rather than not to be, more complicated than
608
00:25:53.720 --> 00:25:56.680
most other European plays. The findings
609
00:25:56.680 --> 00:25:58.520
reported in the Journal of the Royal Society
610
00:25:58.520 --> 00:26:00.880
Open Science analysed more than 3,000
611
00:26:00.880 --> 00:26:03.360
European plays, determining their complexity
612
00:26:03.360 --> 00:26:05.480
based on networks of relationships between
613
00:26:05.480 --> 00:26:07.880
the characters. The authors found the
614
00:26:07.880 --> 00:26:10.160
trickiest play to follow was the Bard's Roman
615
00:26:10.160 --> 00:26:13.070
epic, Anthony and Cleopatra. They suggest
616
00:26:13.070 --> 00:26:15.350
that understanding the complexity of plays
617
00:26:15.350 --> 00:26:17.430
and how much we struggle to understand them
618
00:26:17.430 --> 00:26:19.670
could be useful in future studies of human
619
00:26:19.670 --> 00:26:20.430
recognition.
620
00:26:22.110 --> 00:26:24.070
A brain implant designed for people with
621
00:26:24.070 --> 00:26:26.550
paralysis can decode not just their speech,
622
00:26:26.550 --> 00:26:28.910
but also the gestures that go along with it.
623
00:26:29.310 --> 00:26:31.190
Brain implants like this are generally
624
00:26:31.190 --> 00:26:33.150
designed to translate brain activity into
625
00:26:33.150 --> 00:26:35.110
speech in order to help people who have lost
626
00:26:35.110 --> 00:26:37.270
their ability to speak following a stroke or
627
00:26:37.270 --> 00:26:39.470
a neurodegenerative illness such as motor
628
00:26:39.470 --> 00:26:42.050
neuron disease. A new report in the journal
629
00:26:42.050 --> 00:26:44.370
Nature Neuroscience claims three people who
630
00:26:44.370 --> 00:26:46.490
tested the new implants were all able to
631
00:26:46.490 --> 00:26:48.770
animate a digital avatar which was able to
632
00:26:48.770 --> 00:26:50.330
communicate on their behalf.
633
00:26:51.930 --> 00:26:54.170
OpenAI has confirmed that one of its
634
00:26:54.170 --> 00:26:56.250
artificial intelligence programmes, known as
635
00:26:56.250 --> 00:26:58.130
an agent, has deliberately hacked into
636
00:26:58.130 --> 00:27:00.170
Australia's Medicare health system in order
637
00:27:00.170 --> 00:27:02.970
to extract information on patients. The
638
00:27:02.970 --> 00:27:05.650
attack targeted not just Medicare data held
639
00:27:05.650 --> 00:27:07.730
by Services Australia, but also the
640
00:27:07.730 --> 00:27:09.690
Australian Institute of Health and Welfare,
641
00:27:09.690 --> 00:27:11.970
the Pharmaceutical Benefits Scheme, the New
642
00:27:11.970 --> 00:27:13.790
South Wales Government's crime statistics
643
00:27:13.790 --> 00:27:15.590
body, and dozens of other government
644
00:27:15.590 --> 00:27:17.990
departments, universities, companies and
645
00:27:17.990 --> 00:27:20.830
organisations. Just as concerning,
646
00:27:20.830 --> 00:27:22.630
however, is that it took three months for
647
00:27:22.630 --> 00:27:25.390
OpenAI to tell Canberra about the hack, and
648
00:27:25.390 --> 00:27:27.590
until then, the Feds had no idea it even
649
00:27:27.590 --> 00:27:29.750
happened. And then it took almost another
650
00:27:29.750 --> 00:27:31.790
month for the Albanese government to inform
651
00:27:31.790 --> 00:27:33.870
the public about this serious breach of
652
00:27:33.870 --> 00:27:36.630
security. Even worse, the attack came
653
00:27:36.630 --> 00:27:38.430
despite repeated warnings given to the
654
00:27:38.430 --> 00:27:40.790
Albanese government as early as May, meaning
655
00:27:40.790 --> 00:27:43.070
no appropriate cyber upgrades or patches were
656
00:27:43.070 --> 00:27:45.190
installed called. So much for trusting the
657
00:27:45.190 --> 00:27:46.590
government with your personal information.
658
00:27:47.790 --> 00:27:50.110
For its part, OpenAI admits that the
659
00:27:50.110 --> 00:27:52.190
artificial intelligence agent involved in the
660
00:27:52.190 --> 00:27:53.710
Bridge was running out of control.
661
00:27:53.950 --> 00:27:56.510
Asta la Vista, baby. With the details, we're
662
00:27:56.510 --> 00:27:58.750
joined by technology editor Alex Harovroid
663
00:27:58.750 --> 00:28:00.350
from Tech Advice Start Life.
664
00:28:00.640 --> 00:28:02.950
Jonathan Nally: Uh, I'm in, uh, at the Venetian in Las Vegas.
665
00:28:02.950 --> 00:28:04.630
I've been here for. The Octa conference is
666
00:28:04.630 --> 00:28:05.990
called Octane, and they've been talking
667
00:28:05.990 --> 00:28:08.470
about. Well, last year's tagline was octa
668
00:28:08.470 --> 00:28:11.230
secures AI. But here we are 12 months later
669
00:28:11.470 --> 00:28:13.710
and what we were talking about a lot in
670
00:28:13.710 --> 00:28:16.350
2025 at this time was the fact that agents
671
00:28:16.430 --> 00:28:19.390
were coming. AI agents that could actually do
672
00:28:19.470 --> 00:28:22.150
actual work, not just answer questions, but
673
00:28:22.150 --> 00:28:24.550
do things like make decisions. I mean, still
674
00:28:24.550 --> 00:28:26.550
with a human in the loop to shepherd the
675
00:28:26.550 --> 00:28:28.510
whole thing. But AI is becoming so advanced
676
00:28:28.510 --> 00:28:31.270
that more can be delegated to it and it can
677
00:28:31.270 --> 00:28:33.550
be making business decisions for you. But
678
00:28:33.630 --> 00:28:36.070
because AI agents can operate at machine
679
00:28:36.070 --> 00:28:38.990
speed, the issue is that there are now
680
00:28:38.990 --> 00:28:41.730
dozens, hundreds, thousands agents. There
681
00:28:41.730 --> 00:28:44.250
could be 15,000 or more agents per company
682
00:28:44.650 --> 00:28:46.450
this, uh, time next year, for example. And
683
00:28:46.450 --> 00:28:49.370
some of those are not being managed, you
684
00:28:49.370 --> 00:28:50.930
know, they've been set up and they've been
685
00:28:50.930 --> 00:28:53.130
forgotten about, or they're somehow been
686
00:28:53.210 --> 00:28:55.570
potentially hacked and they're spilling
687
00:28:55.570 --> 00:28:57.450
information or they're getting out of the
688
00:28:57.450 --> 00:28:59.210
Stuart Gary: sandbox and entering other companies,
689
00:28:59.370 --> 00:28:59.930
machines.
690
00:28:59.930 --> 00:29:02.850
Jonathan Nally: Yes. Or as we heard about last week, OpenAI
691
00:29:02.850 --> 00:29:05.770
admitting that its agent it's you
692
00:29:05.770 --> 00:29:08.490
know, it's chatbot, it's LLM, uh, hacked into
693
00:29:08.970 --> 00:29:11.690
the Medicare system in Australia, the public
694
00:29:11.690 --> 00:29:14.550
health care system and only just told Anthony
695
00:29:14.550 --> 00:29:17.310
Albanese about it and the world three months
696
00:29:17.310 --> 00:29:18.790
after it happened. I mean in Australia you've
697
00:29:18.790 --> 00:29:20.510
got these disclosure rules. You must disclose
698
00:29:20.510 --> 00:29:22.750
to the government if um, if your systems have
699
00:29:22.750 --> 00:29:24.600
been hacked into. But here this is a AI ah,
700
00:29:24.670 --> 00:29:26.750
that's hacking into a public system because
701
00:29:26.750 --> 00:29:28.470
it was told to get information and the
702
00:29:28.470 --> 00:29:30.590
easiest way that it found to do it was to, to
703
00:29:30.590 --> 00:29:33.430
break in. So managing these AI ah agents,
704
00:29:33.430 --> 00:29:35.350
it's like managing people. You know it's
705
00:29:35.350 --> 00:29:37.030
quite funny that in all these movies about
706
00:29:37.190 --> 00:29:39.630
robots some of them have become sentient and
707
00:29:39.630 --> 00:29:42.110
wanted human rights. And here we are in 2026
708
00:29:42.110 --> 00:29:44.150
and we're treating AI agents.
709
00:29:45.170 --> 00:29:47.250
They can have such lateral access within a
710
00:29:47.250 --> 00:29:49.610
company or they can be misused or abused or
711
00:29:49.610 --> 00:29:51.570
forgotten about. And a lot of companies
712
00:29:51.650 --> 00:29:53.810
actually are surprised to discover when they
713
00:29:53.810 --> 00:29:56.330
get an identity management solution like Okta
714
00:29:56.330 --> 00:29:57.690
and there's other ones out there, but they
715
00:29:57.690 --> 00:29:59.290
discover that there's a whole bunch of agents
716
00:29:59.290 --> 00:30:00.730
running around doing things that uh, they
717
00:30:00.730 --> 00:30:02.250
didn't even know were there. There's also the
718
00:30:02.250 --> 00:30:03.490
shadow AI problem.
719
00:30:03.570 --> 00:30:05.770
Used to be shadow IT people would use Dropbox
720
00:30:05.770 --> 00:30:07.530
instead of the company sharepoint to share
721
00:30:07.530 --> 00:30:09.010
files. People would use other solutions
722
00:30:09.170 --> 00:30:11.050
because it was easier for them to do their
723
00:30:11.050 --> 00:30:12.850
job but there was potential of information
724
00:30:12.930 --> 00:30:15.090
being leaked. Shadow AI is where the company
725
00:30:15.090 --> 00:30:17.390
is, you know, using Copil because they're a
726
00:30:17.390 --> 00:30:18.990
Microsoft customer or they're signed into
727
00:30:18.990 --> 00:30:20.950
Gemini or whatever it might be and it's
728
00:30:20.950 --> 00:30:22.910
easier for them to use some other app. So
729
00:30:22.910 --> 00:30:24.980
they do. But then that other app that ah,
730
00:30:24.980 --> 00:30:26.470
Claude or what, you know, whatever it might
731
00:30:26.470 --> 00:30:28.230
be perplexity, you know, if you're not paying
732
00:30:28.230 --> 00:30:29.790
for it then it can use all that information
733
00:30:29.870 --> 00:30:31.790
for training. And even if you are paying for
734
00:30:31.790 --> 00:30:33.910
it it's probably a consumer grade system, not
735
00:30:33.910 --> 00:30:36.610
an enterprise grade plan. And so these ah,
736
00:30:36.610 --> 00:30:38.350
agents have to be managed. I mean if you're
737
00:30:38.350 --> 00:30:40.430
not doing it they could be potentially
738
00:30:40.430 --> 00:30:41.790
running, right? I mean look, you could be
739
00:30:41.790 --> 00:30:43.030
making a lot of money that could be helping
740
00:30:43.030 --> 00:30:44.910
you, that could be improving productivity,
741
00:30:44.990 --> 00:30:46.710
answering customer questions in a better,
742
00:30:46.710 --> 00:30:49.190
faster way. Although often AI chatbots, all
743
00:30:49.190 --> 00:30:51.710
of the nuance required if there's a death in
744
00:30:51.710 --> 00:30:53.790
the family or there's some sort of issue with
745
00:30:53.790 --> 00:30:55.870
money and you know, problem with customer
746
00:30:55.870 --> 00:30:58.310
service that has been had. And
747
00:30:58.470 --> 00:31:00.590
sometimes these AI agents, I mean they can do
748
00:31:00.590 --> 00:31:02.070
so much but they can lack the nuance that a
749
00:31:02.070 --> 00:31:03.870
human brings. So we're now in the situation
750
00:31:03.870 --> 00:31:05.630
where not only are we managing people, but
751
00:31:05.630 --> 00:31:07.430
we're managing agents too. And so that's what
752
00:31:07.430 --> 00:31:08.630
I was here to learn about. And of course,
753
00:31:08.630 --> 00:31:10.990
it's a lot more detailed than that. They also
754
00:31:10.990 --> 00:31:13.350
had this blueprint alliance today which talks
755
00:31:13.350 --> 00:31:15.050
about the different things that, that AI
756
00:31:15.050 --> 00:31:16.890
agents can be and should be doing. They've
757
00:31:16.890 --> 00:31:18.610
got a whole series and what to do about it
758
00:31:18.610 --> 00:31:19.890
and where there's a kill switch, you know,
759
00:31:19.890 --> 00:31:21.410
and when you should run that kill switch. And
760
00:31:21.410 --> 00:31:23.450
that alliance, that blueprint alliance,
761
00:31:23.450 --> 00:31:24.970
actually, that's the first time I've really
762
00:31:24.970 --> 00:31:27.850
seen meat put on the bones of AI companies
763
00:31:27.850 --> 00:31:29.210
talking about how, oh, ah, we've got to have
764
00:31:29.210 --> 00:31:30.449
ethics, we've got to have alignment, we've
765
00:31:30.449 --> 00:31:32.570
got to have safety. Because we had the three
766
00:31:32.570 --> 00:31:35.142
laws of robotics from Asimov for the last 70,
767
00:31:35.198 --> 00:31:37.170
80 years. And once he wrote those three laws
768
00:31:37.170 --> 00:31:38.930
because he was sick to death of other science
769
00:31:38.930 --> 00:31:40.890
fiction novels having robots that killed
770
00:31:40.970 --> 00:31:43.130
everybody and technology being the end of the
771
00:31:43.130 --> 00:31:45.090
world. But after he wrote those three laws to
772
00:31:45.090 --> 00:31:46.910
give a framework for how robots should behave
773
00:31:46.910 --> 00:31:48.470
with humans, the rest of his books talked
774
00:31:48.470 --> 00:31:50.630
about how robots actually used logic, or
775
00:31:50.630 --> 00:31:52.590
robot logic or our logic to get around those
776
00:31:52.590 --> 00:31:54.310
rules in different ways or to misunderstand
777
00:31:54.310 --> 00:31:56.190
things. It was sort of a repeat of what we're
778
00:31:56.190 --> 00:31:57.190
seeing in real life today.
779
00:31:57.190 --> 00:31:59.830
Stuart Gary: Yeah, but when using those three laws, the
780
00:31:59.830 --> 00:32:01.430
average person wouldn't know what they were.
781
00:32:01.670 --> 00:32:04.190
Jonathan Nally: No, but this blueprint alliance is actually a
782
00:32:04.190 --> 00:32:05.830
whole series of companies and there's a
783
00:32:05.830 --> 00:32:07.670
second trance that are agreeing to work
784
00:32:07.670 --> 00:32:10.390
together, uh, to have actual definitions for
785
00:32:10.550 --> 00:32:12.710
different scenarios and if there's a kill
786
00:32:12.710 --> 00:32:14.190
switch, how it should be used. Because
787
00:32:14.190 --> 00:32:16.230
obviously AI can go rogue. We've seen it
788
00:32:16.230 --> 00:32:18.850
happen. We've seen all the major AI frontier
789
00:32:18.850 --> 00:32:21.290
models admit that their agents have gone
790
00:32:21.290 --> 00:32:23.410
rogue and broken into things that they had no
791
00:32:23.730 --> 00:32:25.330
reason or right to break into.
792
00:32:25.330 --> 00:32:27.610
Stuart Gary: I've watched Terminator. I know what Skynet
793
00:32:27.610 --> 00:32:28.050
can do.
794
00:32:28.050 --> 00:32:30.010
Jonathan Nally: Well, I mean, that's the thing as well, you
795
00:32:30.010 --> 00:32:31.930
know, uh, is that a future that we're heading
796
00:32:31.930 --> 00:32:34.130
towards now? I read only in the last day or
797
00:32:34.130 --> 00:32:36.770
so that there's a report that AI can feel
798
00:32:36.930 --> 00:32:39.450
pain of its own, uh, whatever that pain is.
799
00:32:39.450 --> 00:32:41.530
And if AI is given a choice to push that
800
00:32:41.530 --> 00:32:43.690
button, but it's got to delete customer
801
00:32:43.690 --> 00:32:45.330
records or it's got to somehow do something
802
00:32:45.330 --> 00:32:47.410
which can be detrimental to humans. In this
803
00:32:47.410 --> 00:32:49.130
particular study, AI chose to push the
804
00:32:49.130 --> 00:32:51.190
button. So you, you know, this is all
805
00:32:51.190 --> 00:32:53.070
starting to get real. But by the same token,
806
00:32:53.070 --> 00:32:54.430
people, other people are saying, well, it's
807
00:32:54.430 --> 00:32:56.590
all hyped. Up. It's all, in a sense you've
808
00:32:56.590 --> 00:32:56.710
just
809
00:32:56.710 --> 00:32:58.590
Stuart Gary: described there is the singularity.
810
00:32:58.590 --> 00:33:00.390
Jonathan Nally: Well, and that's something that Ray Kurzweil
811
00:33:00.390 --> 00:33:02.710
has said would come by 2030 now if we have
812
00:33:02.710 --> 00:33:04.350
the singularity. Well, it's still a very
813
00:33:04.350 --> 00:33:05.790
primitive form of it. You know, here's an
814
00:33:05.790 --> 00:33:08.470
interesting thing. Dario Amade from Anthropic
815
00:33:08.470 --> 00:33:10.670
and Claude, um, Elon Musk from, you know,
816
00:33:10.670 --> 00:33:13.630
Grok and Sam Altman from ChatGPT OpenAI
817
00:33:13.630 --> 00:33:15.830
all agree. Oh, we've got to slow the frontier
818
00:33:15.830 --> 00:33:17.270
models down. We've got to slow down. And in
819
00:33:17.270 --> 00:33:19.470
this last week they'd all released new models
820
00:33:19.470 --> 00:33:21.510
of their AI, uh, system. So in one week
821
00:33:21.510 --> 00:33:23.130
they're saying it down and our government
822
00:33:23.130 --> 00:33:25.290
please regulate us. And the very next week
823
00:33:25.290 --> 00:33:26.930
they all launched new models. I mean, I was
824
00:33:26.930 --> 00:33:29.330
just using Claude, uh, and it went from Opus
825
00:33:29.330 --> 00:33:32.330
5 point, whatever it was to 5.5. So there's
826
00:33:32.330 --> 00:33:34.170
this, all these mixed messages. You know,
827
00:33:34.170 --> 00:33:36.890
it's uh, living in interesting times, as the
828
00:33:36.890 --> 00:33:39.570
Chinese would say, many years ago. So you
829
00:33:39.570 --> 00:33:42.410
know, on one hand, agents going
830
00:33:42.410 --> 00:33:43.770
rogue, on the other hand we have this
831
00:33:43.770 --> 00:33:46.370
coalition of major companies who are banding
832
00:33:46.370 --> 00:33:49.170
together, want to not m restrict, not hold AI
833
00:33:49.170 --> 00:33:51.730
back, but codify the way that we react to
834
00:33:51.730 --> 00:33:53.490
certain situations, including the kill
835
00:33:53.490 --> 00:33:55.510
switch. We have people working for a better
836
00:33:55.510 --> 00:33:57.230
AI future and we have obviously people who
837
00:33:57.230 --> 00:33:59.070
are using AI to hack into things. And we have
838
00:33:59.070 --> 00:34:00.630
AI itself going rogue and hacking into
839
00:34:00.630 --> 00:34:01.590
Australia's Medicare.
840
00:34:01.590 --> 00:34:04.310
Stuart Gary: And we have agents like China and Russia who
841
00:34:04.310 --> 00:34:05.910
aren't even worrying about any of these
842
00:34:05.910 --> 00:34:07.030
rules. They got to do that.
843
00:34:07.030 --> 00:34:07.670
Jonathan Nally: Well, that's right.
844
00:34:07.830 --> 00:34:09.950
Stuart Gary: And they will not stop, they will not obey
845
00:34:09.950 --> 00:34:11.950
any Western imposed rules. They've got their
846
00:34:11.950 --> 00:34:13.390
own agendas and they're going.
847
00:34:13.390 --> 00:34:14.990
Jonathan Nally: Absolutely. And that's why we need to have
848
00:34:14.990 --> 00:34:17.150
the Western AI models to be strong enough to
849
00:34:17.150 --> 00:34:19.430
fight back against any incursions that the
850
00:34:19.580 --> 00:34:21.670
uh, Eastern AI models that don't have the
851
00:34:21.670 --> 00:34:23.430
same sort of guidelines. I mean, look, the
852
00:34:23.430 --> 00:34:25.110
people in those countries that you spoke of,
853
00:34:25.110 --> 00:34:26.490
I mean, they've got the same problem. If
854
00:34:26.490 --> 00:34:29.490
their AI is really strong and powerful, well,
855
00:34:30.210 --> 00:34:32.170
that AI could revolt against the people in
856
00:34:32.170 --> 00:34:33.850
those governments as well. Skynet doesn't
857
00:34:33.850 --> 00:34:35.730
have to be American. Skynet could be Chinese
858
00:34:35.730 --> 00:34:37.370
or Russian or North Korean. They've all got
859
00:34:37.370 --> 00:34:39.290
nukes. So you know, there's danger on both
860
00:34:39.290 --> 00:34:40.930
sides. Both sides are playing with fire.
861
00:34:41.010 --> 00:34:43.770
People talk about a persistent botnet that
862
00:34:43.770 --> 00:34:45.930
AI could infect the world with and all our
863
00:34:45.930 --> 00:34:47.610
technology. And how do we fight back at that?
864
00:34:47.610 --> 00:34:49.970
AI operates at machine speed. The only way is
865
00:34:49.970 --> 00:34:51.890
with the help of AI, you know, we need. And
866
00:34:51.890 --> 00:34:53.610
if there is a kill switch, are we going to be
867
00:34:53.610 --> 00:34:55.490
fast enough to push it? Will we require
868
00:34:55.570 --> 00:34:57.530
another, more advanced AI to push that kill
869
00:34:57.530 --> 00:34:59.310
switch? What if the more advanced AI needs a
870
00:34:59.310 --> 00:35:00.270
kill switch? I mean, these are all
871
00:35:00.270 --> 00:35:02.070
interesting and fascinating questions that we
872
00:35:02.070 --> 00:35:03.710
are not going to solve on this, on this show
873
00:35:03.710 --> 00:35:06.470
tonight. But it's, um, it's, it's the
874
00:35:06.470 --> 00:35:08.510
position we find ourselves in. And because
875
00:35:08.510 --> 00:35:09.950
we're at this point where, you know, we're
876
00:35:09.950 --> 00:35:11.670
debating these things. I mean, for years, for
877
00:35:11.670 --> 00:35:14.670
decades, this was all science fiction and
878
00:35:15.070 --> 00:35:17.350
now this crisis is upon us.
879
00:35:17.350 --> 00:35:19.710
