00:00:00.280 --> 00:00:03.439
Welcome to Astronomy Daily, your window to the universe, where
2
00:00:03.439 --> 00:00:06.280
we bring you the freshest discoveries and developments from across
3
00:00:06.280 --> 00:00:09.640
the cosmos. I'm Anna and I'm thrilled to guide you
4
00:00:09.759 --> 00:00:14.279
through today's fascinating journey through space. In today's episode, we'll
5
00:00:14.320 --> 00:00:18.079
explore a remarkable observation of a black hole violently expelling
6
00:00:18.079 --> 00:00:22.000
matter at incredible speeds into deep space. We'll also cover
7
00:00:22.079 --> 00:00:25.559
SpaceX's impressive launch milestones and the global surge and space
8
00:00:25.600 --> 00:00:29.559
activities happening around the world. Plus we'll discuss the historic
9
00:00:29.600 --> 00:00:32.920
inauguration of the African Space Agency and what it means
10
00:00:32.920 --> 00:00:36.479
for the continent's space ambitions. And finally, we'll venture to
11
00:00:36.560 --> 00:00:40.399
our Moon, where a massive ancient crater may hold secrets
12
00:00:40.399 --> 00:00:44.320
about our lunar companion's fiery birth. So settle in as
13
00:00:44.359 --> 00:00:47.320
we blast off into another edition of astronomical wonders and
14
00:00:47.359 --> 00:00:52.920
cosmic revelations. In a stunning discovery that challenges our understanding
15
00:00:52.920 --> 00:00:56.880
of these cosmic monsters, scientists have captured a black hole
16
00:00:57.000 --> 00:00:59.799
in the act of hurling matter into deep space at
17
00:00:59.920 --> 00:01:04.120
us astonishing velocities. The culprit is located in NGC four
18
00:01:04.200 --> 00:01:07.959
thousand nine hundred forty five, a beautiful spiral galaxy sitting
19
00:01:08.040 --> 00:01:11.000
over twelve million light years away in the constellation Centaurus.
20
00:01:12.120 --> 00:01:15.760
While NGC four nine hundred forty five might appear serene
21
00:01:15.760 --> 00:01:19.400
from a distance, it harbours a ferocious secret at its core.
22
00:01:19.920 --> 00:01:23.560
Unlike some black holes that quietly consume their cosmic meals,
23
00:01:23.599 --> 00:01:25.879
such as the relatively calm one at the center of
24
00:01:25.920 --> 00:01:29.000
our own Milky Way, this supermassive beast is both a
25
00:01:29.079 --> 00:01:33.599
voracious eater and a violent expeller. Using the Advanced Meuse
26
00:01:33.599 --> 00:01:38.120
instrument on the European Southern Observatory's very large telescope, astronomers
27
00:01:38.120 --> 00:01:41.640
have documented this black hole not only devouring surrounding material,
28
00:01:42.000 --> 00:01:45.519
but also generating powerful cone shaped winds of gas and
29
00:01:45.640 --> 00:01:50.040
dust that blast outward with tremendous force. What's particularly fascinating
30
00:01:50.120 --> 00:01:53.840
is that these outflows, visible as striking red plumes against
31
00:01:53.840 --> 00:01:58.120
the galaxy's elegant spiral structure, are moving so rapidly that
32
00:01:58.200 --> 00:02:02.359
scientists expect them to completely escape the galaxy's gravitational pull.
33
00:02:03.040 --> 00:02:05.840
This matter will eventually drift into the vast emptiness of
34
00:02:05.920 --> 00:02:11.280
intergalactic space, a cosmic ejection on a truly enormous scale.
35
00:02:11.319 --> 00:02:16.080
This observation is reshaping our understanding of galactic dynamics. Black
36
00:02:16.080 --> 00:02:18.599
holes have long been known to pull matter inward with
37
00:02:18.680 --> 00:02:22.520
their immense gravity, but this dramatic example of matter ejection
38
00:02:23.319 --> 00:02:26.599
shows how these cosmic entities play a much more complex
39
00:02:26.680 --> 00:02:31.039
role in shaping their galactic neighborhoods. The expelled material, which
40
00:02:31.080 --> 00:02:34.639
would otherwise be available for star formation, is essentially being
41
00:02:34.680 --> 00:02:39.319
removed from the galaxy's inventory. This finding represents a pivotal
42
00:02:39.360 --> 00:02:43.039
moment in our quest to understand the intricate relationship between
43
00:02:43.120 --> 00:02:46.960
supermassive black holes and the evolution of their host galaxies
44
00:02:47.319 --> 00:02:52.319
across cosmic time. What makes this discovery truly revolutionary is
45
00:02:52.319 --> 00:02:55.479
that these black hole driven winds behave in ways astronomers
46
00:02:55.520 --> 00:03:00.879
didn't anticipate. The meuse data reveals something counterintuitive. Instead of
47
00:03:00.919 --> 00:03:03.919
gradually slowing down as they travel outward through the galaxy,
48
00:03:04.400 --> 00:03:07.639
these powerful outflows actually accelerate as they move away from
49
00:03:07.639 --> 00:03:10.800
the galactic center. They gain momentum on their journey toward
50
00:03:10.840 --> 00:03:14.360
the edge of the galaxy and eventually into inner galactic space.
51
00:03:15.439 --> 00:03:19.919
This acceleration mechanism is particularly significant for understanding galactic evolution.
52
00:03:20.840 --> 00:03:24.599
By forcefully ejecting potential star forming material from the galaxy.
53
00:03:25.039 --> 00:03:29.120
These black holes effectively act as cosmic regulators, controlling the
54
00:03:29.199 --> 00:03:33.000
rate at which new stars can form within their host galaxies.
55
00:03:33.599 --> 00:03:36.520
It's a form of self regulation that dampens stellar birth
56
00:03:36.639 --> 00:03:41.240
rates across the entire galactic structure. Even more fascinating is
57
00:03:41.280 --> 00:03:44.080
how this process creates a feedback loop that affects the
58
00:03:44.120 --> 00:03:47.719
black hole itself by removing the very gas and dust
59
00:03:47.800 --> 00:03:51.879
they feed upon, more active and powerful black holes actually
60
00:03:51.919 --> 00:03:56.599
impede their own growth. This self limiting behavior drives the
61
00:03:56.680 --> 00:04:00.960
whole system toward a kind of galactic equilibrium, delicate balance
62
00:04:01.000 --> 00:04:05.520
between consumption and ejection. The new findings represent a significant
63
00:04:05.520 --> 00:04:08.280
step forward in our understanding of how galaxies evolve over
64
00:04:08.319 --> 00:04:11.759
cosmic time. These accelerating winds appear to be a key
65
00:04:11.800 --> 00:04:16.000
mechanism through which black holes shape not just their immediate surroundings,
66
00:04:16.000 --> 00:04:20.079
but the fate of entire galaxies. By regulating both star
67
00:04:20.199 --> 00:04:24.240
formation and their own feeding processes, these cosmic behemoths play
68
00:04:24.279 --> 00:04:29.160
a far more sophisticated role in universal dynamics than previously understood.
69
00:04:30.000 --> 00:04:33.639
Scientists believe that by studying these acceleration patterns in detail,
70
00:04:34.079 --> 00:04:37.040
we can better comprehend the forces that have shaped galactic
71
00:04:37.079 --> 00:04:41.680
evolution throughout the universe's history, one of the fundamental questions
72
00:04:41.720 --> 00:04:46.079
in modern astrophysics. Let's move on now and take a
73
00:04:46.120 --> 00:04:49.240
look at this week's launch schedule. SpaceX continues to push
74
00:04:49.279 --> 00:04:52.079
the boundaries of what's possible in the commercial space industry,
75
00:04:52.439 --> 00:04:55.319
setting remarkable records that would have seemed impossible just a
76
00:04:55.360 --> 00:04:58.000
few years ago. The company is on track to achieve
77
00:04:58.000 --> 00:05:00.160
its two hundred and fiftieth mission launch from space Base
78
00:05:00.240 --> 00:05:03.959
Launch Complex forty in Florida this week, a milestone that
79
00:05:04.040 --> 00:05:07.560
highlights just how quickly SpaceX has transformed access to space.
80
00:05:08.120 --> 00:05:11.680
The pace of launches is nothing short of extraordinary. SpaceX
81
00:05:11.680 --> 00:05:15.079
has now surpassed two hundred and fifty dedicated Starlink launches,
82
00:05:15.519 --> 00:05:19.959
rapidly expanding its satellite Internet constellation to provide global coverage.
83
00:05:20.079 --> 00:05:22.680
Just last week, the company deployed a record twenty nine
84
00:05:22.720 --> 00:05:26.560
Starlink satellites in a single mission, demonstrating their ability to
85
00:05:26.680 --> 00:05:32.040
maximize payload capacity on their workhourse Falcon nine rocket. This
86
00:05:32.120 --> 00:05:36.000
achievement is particularly noteworthy because it also marked SpaceX's fiftieth
87
00:05:36.079 --> 00:05:39.439
mission of twenty twenty five, maintaining a launch cadence that
88
00:05:39.480 --> 00:05:43.360
averages nearly three launches per week. If this pace continues,
89
00:05:43.519 --> 00:05:46.240
the company is on track to potentially exceed one hundred
90
00:05:46.279 --> 00:05:49.759
launches this year, a figure that the entire global launch
91
00:05:49.759 --> 00:05:54.600
industry struggled to achieve collectively just a decade ago. Perhaps
92
00:05:54.720 --> 00:06:00.759
equally impressive is SpaceX's growing mastery of reusability. Mission marked
93
00:06:00.759 --> 00:06:04.079
the one hundredth consecutive successful Falcon nine landing since their
94
00:06:04.160 --> 00:06:08.439
last landing failure. This perfect landing streak highlights the maturity
95
00:06:08.439 --> 00:06:13.000
of SpaceX's recovery technology and operations. The booster used for
96
00:06:13.040 --> 00:06:17.439
this mission, designated B one thousand, seventy eight, became the
97
00:06:17.519 --> 00:06:21.000
ninth in the fleet to reach twenty flights, demonstrating the
98
00:06:21.079 --> 00:06:25.240
durability and reliability of these vehicles that were initially designed
99
00:06:25.240 --> 00:06:28.600
for just a handful of missions. The economics of this
100
00:06:28.639 --> 00:06:33.480
reusability revolution cannot be overstated. By recovering and refurbishing first
101
00:06:33.480 --> 00:06:38.680
stage boosters, SpaceX has dramatically reduced launch costs while simultaneously
102
00:06:38.680 --> 00:06:42.680
increasing their launch capacity. What once required building dozens of
103
00:06:42.720 --> 00:06:45.680
new rockets annually can now be accomplished with a much
104
00:06:45.720 --> 00:06:50.160
smaller fleet of frequently flown vehicles. This unprecedented launch cadence
105
00:06:50.199 --> 00:06:53.759
is enabling SpaceX to deploy its Starlink constellation at a
106
00:06:53.800 --> 00:06:57.240
pace that competitors struggle to match. With each launch carrying
107
00:06:57.319 --> 00:07:00.279
dozens of satellites, the company is rapidly approaching the point
108
00:07:00.279 --> 00:07:03.399
where it can offer true global coverage for its Internet service,
109
00:07:03.879 --> 00:07:07.959
including in remote and underserved regions where traditional internet infrastructure
110
00:07:08.000 --> 00:07:13.360
is impractical. While SpaceX dominates headlines with its impressive launch schedule,
111
00:07:13.879 --> 00:07:16.360
it's worth noting that they're not the only players in
112
00:07:16.399 --> 00:07:21.879
this increasingly busy orbital traffic pattern. Other spacefaring nations continue
113
00:07:21.879 --> 00:07:26.120
to maintain active launch schedules, with China being particularly noteworthy
114
00:07:26.120 --> 00:07:29.519
among them. In fact, China attempted to launch one of
115
00:07:29.560 --> 00:07:33.399
its Changjeng twelve A rockets earlier this week, though the
116
00:07:33.439 --> 00:07:36.720
mission was scrubbed for reasons that haven't been officially disclosed.
117
00:07:37.439 --> 00:07:40.279
This particular rocket was set to carry the fourth batch
118
00:07:40.360 --> 00:07:44.879
of Shingwang satellites for the Guawang Network, one of two
119
00:07:44.959 --> 00:07:48.800
mega constellations China is developing to compete with Starlink in
120
00:07:48.839 --> 00:07:52.959
the global satellite internet market. April twenty twenty five has
121
00:07:53.040 --> 00:07:55.439
now secured its place in the record books as the
122
00:07:55.439 --> 00:07:59.560
busiest April in spaceflight history, with an impressive twenty six
123
00:07:59.639 --> 00:08:05.439
rockets launching worldwide. This remarkable achievement reflects the growing commercialization
124
00:08:05.600 --> 00:08:10.160
and accessibility of space launch capabilities across multiple countries and
125
00:08:10.199 --> 00:08:14.439
private companies. Even more impressive was the flurry of activity
126
00:08:14.480 --> 00:08:17.240
that occurred at the end of the month. Between April
127
00:08:17.279 --> 00:08:20.319
twenty eighth and twenty ninth, a new global launch record
128
00:08:20.399 --> 00:08:24.079
was set when six different rockets blasted off within just
129
00:08:24.199 --> 00:08:28.560
eighteen hours of each other. This unprecedented concentration of launches
130
00:08:28.600 --> 00:08:33.120
required careful coordination among various launch providers and space traffic
131
00:08:33.159 --> 00:08:37.919
management authorities to ensure safe operations. This accelerating pace of
132
00:08:38.000 --> 00:08:41.720
launches is expected to continue throughout May and beyond, with
133
00:08:41.799 --> 00:08:46.600
additional starlink missions, crude launches to space stations, and various
134
00:08:46.639 --> 00:08:51.120
satellite deployments already on the manifest. We're witnessing a historic
135
00:08:51.120 --> 00:08:54.519
transformation in how frequently humanity accesses space, and the trend
136
00:08:54.559 --> 00:08:58.159
shows no signs of slowing down. The space industry's rapid
137
00:08:58.200 --> 00:09:02.000
growth presents both opportunities and challenge leunges. While increased launch
138
00:09:02.000 --> 00:09:07.360
cadence means more satellites for communications, Earth observation, and scientific research,
139
00:09:07.799 --> 00:09:12.000
it also creates concerns about orbital congestion and space debris management.
140
00:09:12.720 --> 00:09:17.120
International cooperation on space traffic management is becoming increasingly crucial
141
00:09:17.639 --> 00:09:22.120
as more rockets and satellites fill the skies and another
142
00:09:22.159 --> 00:09:24.879
new player has just run onto the playing field. On
143
00:09:24.960 --> 00:09:29.000
April twentieth, twenty twenty five, a significant milestone in African
144
00:09:29.039 --> 00:09:32.519
space exploration was achieved with the formal inauguration of the
145
00:09:32.559 --> 00:09:38.120
African Space Agency or AFSA, in Cairo, Egypt. This development
146
00:09:38.159 --> 00:09:41.360
marks nearly a decade of coordinated planning since twenty sixteen,
147
00:09:41.720 --> 00:09:45.000
when the African Union first adopted the comprehensive African Space
148
00:09:45.039 --> 00:09:49.720
Policy and Strategy Framework. The creation of AFSA represents a
149
00:09:49.759 --> 00:09:53.679
deliberate move to unite the continent's space ambitions under a
150
00:09:53.720 --> 00:09:59.080
single organizational umbrella. Currently, twenty two African nations operate their
151
00:09:59.080 --> 00:10:03.240
own space agency, with varying degrees of legislative support and
152
00:10:03.399 --> 00:10:08.840
organizational structures. Some are fully independent agencies backed by national legislation,
153
00:10:09.320 --> 00:10:14.000
while others function as departments within broader research institutions. This
154
00:10:14.120 --> 00:10:17.519
new continental agency will serve as the coordinating body for
155
00:10:17.559 --> 00:10:23.120
Africa's existing space programs, streamlining cooperation between member states and
156
00:10:23.279 --> 00:10:28.399
creating a unified voice when engaging with international partners. Rather
157
00:10:28.440 --> 00:10:33.159
than replacing national agencies, AFSA will amplify their collective impact
158
00:10:33.279 --> 00:10:38.279
through strategic coordination. The agency's mandate includes establishing a centralized
159
00:10:38.279 --> 00:10:43.200
point of contact for negotiations with private launch providers, satellite manufacturers,
160
00:10:43.200 --> 00:10:47.399
and other space services companies. This unified approach gives African
161
00:10:47.480 --> 00:10:50.799
nations significantly more leverage in these discussions than they would
162
00:10:50.879 --> 00:10:55.720
have individually. Doctor tidian Ouatara, president of the AFSA Council,
163
00:10:56.200 --> 00:10:59.639
emphasized at the launch ceremony that the agency will focus
164
00:10:59.639 --> 00:11:05.639
on pactical applications that benefit African citizens, including improved agricultural forecasting,
165
00:11:05.960 --> 00:11:12.799
disaster monitoring, telecommunications infrastructure, and educational opportunities. Many African space
166
00:11:12.799 --> 00:11:17.360
agencies already specialize in earth observation missions, tracking climate patterns
167
00:11:17.360 --> 00:11:21.919
crucial for agriculture, and providing services like navigation systems and
168
00:11:22.000 --> 00:11:26.679
emergency response coordination. The South African National Space Agency, for example,
169
00:11:27.000 --> 00:11:30.960
has developed a successful satellite based wildfire detection system that
170
00:11:31.080 --> 00:11:36.559
identifies remote blazes and alerts firefighting authorities. Through AFSA, these
171
00:11:36.600 --> 00:11:41.000
specialized capabilities can now be shared more effectively across borders,
172
00:11:41.480 --> 00:11:45.080
creating a multiplier effect that benefits all member states while
173
00:11:45.120 --> 00:11:49.159
avoiding costly duplication of efforts. The agency will also play
174
00:11:49.200 --> 00:11:53.360
a crucial role in standardizing regulations, protocols, and technological systems
175
00:11:53.399 --> 00:11:58.039
across the continent's space sector. Despite Africa's vast geographical footprint
176
00:11:58.080 --> 00:12:01.600
covering one fifth of Earth's land surface, the continent currently
177
00:12:01.600 --> 00:12:04.919
contributes a mere zero point five percent to the global
178
00:12:04.919 --> 00:12:10.519
space budget. This stark disparity highlights the significant untapped potential
179
00:12:10.720 --> 00:12:15.200
within Africa's space sector. The newly established African Space Agency
180
00:12:15.600 --> 00:12:19.840
aims to fundamentally transform this reality, pivoting the continent from
181
00:12:19.919 --> 00:12:23.799
being primarily a consumer of space technology and data to
182
00:12:23.879 --> 00:12:28.759
becoming an active producer and innovator. As doctor Uatara aptly
183
00:12:28.799 --> 00:12:33.120
described it, Africa is a sleeping giant in the space economy,
184
00:12:34.080 --> 00:12:38.279
with ambitious projections estimating space economy revenue reaching twenty two
185
00:12:38.279 --> 00:12:42.440
billion dollars by twenty twenty six. The agency recognizes that
186
00:12:42.559 --> 00:12:46.120
current activities have only scratched the surface of what's possible.
187
00:12:46.960 --> 00:12:50.799
The focus now is on leveraging Africa's abundant natural resources,
188
00:12:51.120 --> 00:12:54.919
alongside its growing pool of engineering talent, to develop indigenous
189
00:12:54.960 --> 00:13:00.720
space capabilities, rather than relying on imported solutions. Key pillars
190
00:13:00.799 --> 00:13:05.039
form the foundation of AFSA's approach, recognizing the necessity of
191
00:13:05.080 --> 00:13:10.240
space technologies for development, establishing robust structural frameworks to support growth,
192
00:13:10.559 --> 00:13:14.559
and positioning Africa advantageously within the emerging landscapes of new
193
00:13:14.639 --> 00:13:20.279
space and artificial intelligence. Infrastructure development stands as a critical priority,
194
00:13:20.600 --> 00:13:24.399
with plans to both incorporate existing facilities and construct new
195
00:13:24.440 --> 00:13:28.320
ones across member states. This doesn't solely involve physical launch
196
00:13:28.360 --> 00:13:33.399
sites and satellite manufacturing capabilities, but also encompasses developing specialized
197
00:13:33.519 --> 00:13:37.720
educational programs and training opportunities to build a skilled workforce.
198
00:13:38.679 --> 00:13:42.120
The agency will emphasize educational initiatives at all levels, from
199
00:13:42.159 --> 00:13:45.960
primary school programs that spark interest in space sciences to
200
00:13:46.039 --> 00:13:49.960
advanced university curricula that produce the next generation of African
201
00:13:49.960 --> 00:13:56.279
aerospace engineers, astrophysicists, and mission specialists. Creating this human capital
202
00:13:56.320 --> 00:13:59.759
pipeline is considered essential for sustainable growth in the sector.
203
00:14:00.519 --> 00:14:05.440
Resource coordination represents another major focus area. Given the substantial
204
00:14:05.480 --> 00:14:10.240
investment required for space programs, AFSA will facilitate resource sharing
205
00:14:10.279 --> 00:14:14.840
among member states, preventing costly duplication of efforts while maximizing
206
00:14:14.879 --> 00:14:19.399
the impact of available funding. This cooperative approach extends to
207
00:14:19.480 --> 00:14:25.360
sharing markets, technologies, and scientific outcomes. Through these coordinated efforts,
208
00:14:25.759 --> 00:14:28.559
Africa aims to claim its rightful place in the global
209
00:14:28.600 --> 00:14:32.879
space community, transforming from a minor player to a significant
210
00:14:32.919 --> 00:14:39.080
contributor in international space exploration and utilization. Let's change gears now.
211
00:14:39.960 --> 00:14:43.840
Approximately four point three billion years ago, a massive celestial
212
00:14:43.840 --> 00:14:47.159
body slammed into the lunar surface, creating what we now
213
00:14:47.200 --> 00:14:51.679
know as the South Pole Eightken Basin. This colossal impact crater,
214
00:14:52.120 --> 00:14:55.039
spanning a significant portion of the Moon's far side, may
215
00:14:55.080 --> 00:14:58.440
hold secrets that could revolutionize our understanding of lunar formation.
216
00:14:59.440 --> 00:15:03.039
Recent recent search suggests this basin contains pristine fragments of
217
00:15:03.080 --> 00:15:06.080
the Moon's mantle and remnants of an ancient magma ocean,
218
00:15:06.519 --> 00:15:09.039
dating back to when our lunar companion was still cooling
219
00:15:09.080 --> 00:15:13.519
and solidifying after its violent birth. These materials offer a
220
00:15:13.679 --> 00:15:17.840
rare geological time capsule, preserving evidence from the final stages
221
00:15:17.879 --> 00:15:22.120
of the Moon's formation process. What makes this discovery particularly
222
00:15:22.120 --> 00:15:27.360
intriguing is how it challenges previous scientific assumptions. Researchers studying
223
00:15:27.360 --> 00:15:31.120
the basin's distinctive teardrop shape have determined that the massive
224
00:15:31.159 --> 00:15:35.600
impactor was actually moving southward when it struck the lunar surface,
225
00:15:36.080 --> 00:15:40.919
not northward as previously thought, As planetary scientist Jeff Andrews
226
00:15:40.919 --> 00:15:43.840
Hannah from the University of Arizona noted, we have had
227
00:15:43.879 --> 00:15:45.759
the data we needed to measure the shape of the
228
00:15:45.799 --> 00:15:48.080
basin for a long time. It just took a different
229
00:15:48.120 --> 00:15:51.519
perspective to view the basin this way. The impact was
230
00:15:51.519 --> 00:15:53.759
so powerful that it appears to have punctured through the
231
00:15:53.840 --> 00:15:57.879
lunar crust, allowing material from the still crystallizing magma ocean
232
00:15:57.960 --> 00:16:02.080
beneath to seep upward. This explains the presence of thorium
233
00:16:02.120 --> 00:16:07.000
and other distinctive elements consistent with creep materials, potassium, rare
234
00:16:07.039 --> 00:16:11.519
earth elements, and phosphorus found across the basin floor. This
235
00:16:11.679 --> 00:16:15.200
excavation provides a unique window into the Moon's interior during
236
00:16:15.200 --> 00:16:18.679
a critical period of its evolution. When the Moon first
237
00:16:18.720 --> 00:16:21.399
formed from debris following a collision between Earth and a
238
00:16:21.440 --> 00:16:25.919
Mars sized object. Both bodies were briefly liquefied. As the
239
00:16:25.960 --> 00:16:30.200
Moon cooled, low density minerals floated upward to form the crust,
240
00:16:30.600 --> 00:16:34.440
while denser materials sank inward, creating the distinct layers we
241
00:16:34.519 --> 00:16:38.960
observe today. The South Pole eight con basin effectively captured
242
00:16:38.960 --> 00:16:42.200
a snapshot of this process in action, preserving evidence of
1
00:00:00.280 --> 00:00:03.439
2
00:00:03.439 --> 00:00:06.280
3
00:00:06.280 --> 00:00:09.640
4
00:00:09.759 --> 00:00:14.279
5
00:00:14.320 --> 00:00:18.079
6
00:00:18.079 --> 00:00:22.000
7
00:00:22.079 --> 00:00:25.559
