dark energy. Stay with us as we journey through these

18
00:01:03.479 --> 00:01:08.560
remarkable developments in space exploration and astronomical discovery. Let's get started.

19
00:01:10.000 --> 00:01:14.079
In a groundbreaking development from Australia, Astronomers and engineers at

20
00:01:14.079 --> 00:01:20.079
CSIRO have unveiled Kracko, a revolutionary telescope technology that's transforming

21
00:01:20.120 --> 00:01:24.120
our ability to detect mysterious signals from deep space. Think

22
00:01:24.120 --> 00:01:26.920
of it as a cosmic treasure hunter, sifting through an

23
00:01:26.959 --> 00:01:30.120
astronomical amount of data to find rare cosmic events with

24
00:01:30.239 --> 00:01:35.439
remarkable precision. To put its capabilities into perspective, Cracko processes

25
00:01:35.480 --> 00:01:39.560
an astounding one hundred billion pixels per second that's equivalent

26
00:01:39.560 --> 00:01:42.599
to searching through an entire beach of sand every minute

27
00:01:42.599 --> 00:01:46.799
to find a single five cent coin. This incredible processing

28
00:01:46.840 --> 00:01:50.719
power has already led to several major discoveries, including multiple

29
00:01:50.760 --> 00:01:54.239
fast radio bursts and the detection of two previously unknown

30
00:01:54.239 --> 00:01:58.519
neutron stars. During its initial trial run, the system surpassed

31
00:01:58.599 --> 00:02:02.040
all expectations. Doctor Andy Wang and his team at the

32
00:02:02.079 --> 00:02:05.879
International Center for Radio Astronomy Research have already used Kracko

33
00:02:05.959 --> 00:02:09.960
to identify more than twenty fast radio bursts, mysterious cosmic

34
00:02:10.000 --> 00:02:13.680
phenomena that have puzzled astronomers for years. The system can

35
00:02:13.759 --> 00:02:16.840
search for these bursts one hundred times per second, with

36
00:02:16.960 --> 00:02:19.680
plans to increase this to an impressive one thousand times

37
00:02:19.680 --> 00:02:23.120
per second in the future. The technology operates as part

38
00:02:23.159 --> 00:02:26.960
of the ASCAP Radio Telescope at in yarimanha Ilgari Bundhara,

39
00:02:27.360 --> 00:02:32.400
the CSIRO Murchison Radio Astronomy Observatory. What makes KRACKO particularly

40
00:02:32.439 --> 00:02:35.479
special is its ability to instantly alert researchers when it

41
00:02:35.520 --> 00:02:40.199
detects something unusual, allowing for immediate follow up observations and analysis.

42
00:02:41.199 --> 00:02:45.240
This technological breakthrough isn't just about finding cosmic signals, it's

43
00:02:45.280 --> 00:02:49.439
about understanding them. KRACKO has already helped detect long period

44
00:02:49.479 --> 00:02:53.719
transience mysterious objects within our galaxy that we're only beginning

45
00:02:53.759 --> 00:02:58.080
to understand. These discoveries are reinforcing Australia's position as a

46
00:02:58.159 --> 00:03:01.960
leader in radio astronomy engineering and research, with the technology

47
00:03:02.039 --> 00:03:05.960
soon to be made available to astronomers worldwide through csio's

48
00:03:06.000 --> 00:03:10.599
Australia Telescope National Facility. The implications of this technology extend

49
00:03:10.639 --> 00:03:14.800
far beyond its immediate discoveries, by providing astronomers with unprecedented

50
00:03:14.840 --> 00:03:19.240
capabilities to detect and analyze cosmic signals Kracko is opening

51
00:03:19.280 --> 00:03:23.560
new windows into understanding the universe's most enigmatic phenomena, from

52
00:03:23.599 --> 00:03:26.319
the nature of fast radio bursts to the behavior of

53
00:03:26.360 --> 00:03:30.240
neutron stars. Now, let's take a look at what's headed

54
00:03:30.240 --> 00:03:33.240
for space this coming week. And this week's launch schedule

55
00:03:33.319 --> 00:03:37.680
is packed with activity across multiple continents, showcasing the increasingly

56
00:03:37.719 --> 00:03:41.960
busy nature of our space industry. SpaceX leads the charge

57
00:03:41.960 --> 00:03:45.520
with four planned missions utilizing all three of their active

58
00:03:45.599 --> 00:03:50.599
launch sites. Among these are multiple Starlink satellite deployments, continuing

59
00:03:50.639 --> 00:03:54.400
their efforts to expand global Internet coverage. Blue Origin is

60
00:03:54.400 --> 00:03:58.240
preparing for a fascinating, uncrude New Shepherd flight that will

61
00:03:58.280 --> 00:04:02.560
carry out groundbreaking research. The mission will host thirty payloads,

62
00:04:02.680 --> 00:04:07.360
with NASA contributing seventeen different experiments designed to test technologies

63
00:04:07.360 --> 00:04:11.759
for future lunar missions. What makes this flight particularly interesting

64
00:04:12.199 --> 00:04:16.040
is its ability to simulate lunar gravity conditions. The capsule

65
00:04:16.079 --> 00:04:19.959
will spin at approximately eleven revolutions per minute, creating an

66
00:04:20.079 --> 00:04:23.639
environment that mimics the Moon's gravitational pull for about two minutes,

67
00:04:24.160 --> 00:04:29.439
significantly longer than previous simulation methods. India Space Agency ISRO

68
00:04:29.959 --> 00:04:33.680
is set to launch their NVS zero two navigation satellite

69
00:04:34.040 --> 00:04:38.160
aboard a GSLV Mark two rocket. This satellite will join

70
00:04:38.240 --> 00:04:43.360
India's navic constellation, providing enhanced positioning accuracy across the Indian

71
00:04:43.399 --> 00:04:47.480
subcontinent and extending roughly one thousan five hundred kilometers beyond

72
00:04:47.519 --> 00:04:51.680
its borders. The satellite carries cutting edge technology, including an

73
00:04:51.720 --> 00:04:57.040
indigenous atomic clock that uses rubidium atoms for ultra precise timekeeping. Meanwhile,

74
00:04:57.120 --> 00:05:00.439
Japan is preparing to launch their H three rocket carrying

75
00:05:00.480 --> 00:05:04.439
the Mitchibiki six navigation satellite, which aims to improve GPS

76
00:05:04.480 --> 00:05:08.959
accuracy from meters to centimeter level precision. The Spanish military

77
00:05:09.000 --> 00:05:12.040
is also joining the launch manifest with their next generation

78
00:05:12.079 --> 00:05:17.160
telecommunication satellite spainsat NGNG one, scheduled for deployment aboard a

79
00:05:17.199 --> 00:05:20.680
Falcon nine rocket. Lab rounds out the schedule with another

80
00:05:20.720 --> 00:05:24.360
commercial launch from their New Zealand facility, continuing their series

81
00:05:24.360 --> 00:05:28.000
of missions for French customer Quinais. This diverse array of

82
00:05:28.079 --> 00:05:32.160
launches demonstrates how space access has become increasingly routine and

83
00:05:32.199 --> 00:05:36.879
commercially vital, with applications ranging from navigation and communication to

84
00:05:36.959 --> 00:05:41.399
scientific research and technological demonstration. The pace of launches we're

85
00:05:41.399 --> 00:05:43.680
seeing this month suggests we might be on track for

86
00:05:43.720 --> 00:05:47.519
a record breaking year in orbital missions, highlighting the growing

87
00:05:47.560 --> 00:05:52.720
importance of space based infrastructure in our modern world. Next,

88
00:05:52.759 --> 00:05:57.399
an exciting update from the JWST. The James Webb Space

89
00:05:57.480 --> 00:06:01.319
Telescope has made an extraordinary discovery that's challenging our understanding

90
00:06:01.319 --> 00:06:05.319
of the early universe. Astronomers have identified several super massive

91
00:06:05.360 --> 00:06:07.920
black holes that appear to be far too massive compared

92
00:06:07.920 --> 00:06:11.000
to their host galaxies, breaking the rules we thought we

93
00:06:11.120 --> 00:06:16.199
understood about galactic evolution in our nearby universe. Super Massive

94
00:06:16.240 --> 00:06:19.680
black holes typically have masses equal to about zero point

95
00:06:19.839 --> 00:06:25.040
zero one percent of their host galaxies stellar mass. However,

96
00:06:25.079 --> 00:06:27.920
these newly discovered black holes from the early Universe tell

97
00:06:27.959 --> 00:06:33.160
a dramatically different story. Statistical calculations show they possess masses

98
00:06:33.240 --> 00:06:37.879
equal to roughly ten percent of their host galaxies stellar mass,

99
00:06:37.920 --> 00:06:41.680
making them approximately one thousand times more massive than expected.

100
00:06:42.560 --> 00:06:45.279
These findings were made possible through Web's observations of what

101
00:06:45.319 --> 00:06:50.360
astronomers are calling little red dot galaxies. These peculiar objects

102
00:06:50.399 --> 00:06:53.279
existed just one point five billion years after the Big Bang,

103
00:06:53.720 --> 00:06:57.279
when the universe was merely eleven percent of its current age.

104
00:06:57.319 --> 00:07:00.360
Their reddish appearance comes from the gas and dust rounding

105
00:07:00.360 --> 00:07:04.680
actively feeding black holes, creating what we call active galactic nuclei.

106
00:07:05.240 --> 00:07:08.560
The discovery could help solve one of astronomy's most perplexing mysteries,

107
00:07:09.360 --> 00:07:12.160
how super massive black holes managed to grow to such

108
00:07:12.279 --> 00:07:16.720
enormous sizes so quickly in the universe's youth. Traditional theories

109
00:07:16.720 --> 00:07:19.199
suggest that black holes should take more than a billion

110
00:07:19.279 --> 00:07:23.279
years to reach such massive proportions through standard growth processes

111
00:07:23.360 --> 00:07:27.600
like mergers and steady accretion of matter. One possible explanation

112
00:07:27.839 --> 00:07:30.439
is that black holes in the early universe grew much

113
00:07:30.439 --> 00:07:34.399
more efficiently than their modern counterparts, possibly due to the

114
00:07:34.480 --> 00:07:38.279
higher density of gas available in the early cosmos. This

115
00:07:38.480 --> 00:07:41.439
environment may have allowed them to consume surrounding matter at

116
00:07:41.519 --> 00:07:46.120
rates far exceeding what we observe today. These findings suggest

117
00:07:46.199 --> 00:07:49.160
that the formation of stars and super massive black holes

118
00:07:49.160 --> 00:07:53.439
in early galaxies might be more intrinsically linked than previously thought.

119
00:07:54.600 --> 00:07:57.120
While these ancient black holes appear to have grown at

120
00:07:57.160 --> 00:08:01.720
extraordinary rates initially, the star formation in their host galaxies

121
00:08:02.199 --> 00:08:05.879
eventually caught up, leading to the more balanced ratios we

122
00:08:05.920 --> 00:08:10.120
observe in nearby galaxies. Today, and while we're talking new

123
00:08:10.160 --> 00:08:14.439
research findings, new research is shedding fascinating light on two

124
00:08:14.720 --> 00:08:18.360
very different aspects of our cosmic neighborhood, from the universe's

125
00:08:18.399 --> 00:08:21.879
first stars to the winds on Mars. Let's start with

126
00:08:21.920 --> 00:08:24.879
an intriguing study about the earliest stars ever to exist,

127
00:08:24.959 --> 00:08:29.079
known as Population three stars. These cosmic giants were thought

128
00:08:29.120 --> 00:08:31.680
to be some of the most massive stars ever formed,

129
00:08:32.080 --> 00:08:35.200
but scientists have now discovered that their growth wasn't limitless.

130
00:08:35.720 --> 00:08:40.960
Through detailed simulations that incorporate magnetic fields, a factor previously overlooked,

131
00:08:41.480 --> 00:08:44.840
researchers found that these ancient stars could only grow to

132
00:08:44.919 --> 00:08:48.200
about sixty five times the mass of our Sun. This

133
00:08:48.279 --> 00:08:52.559
is significantly less than previous estimates that suggested masses of

134
00:08:52.679 --> 00:08:55.840
up to one hundred and twenty solar masses when magnetic

135
00:08:55.879 --> 00:08:59.879
fields weren't considered. The key finding here is that magnetic

136
00:09:00.080 --> 00:09:03.559
fields acted as a natural break on star growth, even

137
00:09:03.639 --> 00:09:07.080
before other limiting factors like radiation pressure came into play.

138
00:09:07.720 --> 00:09:10.919
These fields worked against gravity, restricting the amount of gas

139
00:09:10.919 --> 00:09:14.080
that could fall onto the forming star. This new understanding

140
00:09:14.120 --> 00:09:16.519
helps explain why we don't see evidence of even more

141
00:09:16.519 --> 00:09:20.600
massive stars in the early universe. Meanwhile, closer to home,

142
00:09:21.039 --> 00:09:25.840
NASA's Ingenuity helicopter has been revolutionizing our understanding of Mars's atmosphere.

143
00:09:26.600 --> 00:09:29.559
During its remarkable seventy two flights on the red planet,

144
00:09:29.919 --> 00:09:32.919
this small but mighty aircraft has recorded wind speeds that

145
00:09:32.960 --> 00:09:37.320
are considerably higher than what our models predicted. Previous estimates

146
00:09:37.360 --> 00:09:41.480
suggested Martian winds wouldn't exceed fifteen meters per second, but

147
00:09:41.759 --> 00:09:45.159
Ingenuity encountered speeds as high as twenty five meters per

148
00:09:45.159 --> 00:09:49.279
second at various altitudes between three and twenty four meters

149
00:09:49.279 --> 00:09:52.799
above the surface. This discovery was made possible through an

150
00:09:53.000 --> 00:09:57.159
ingenious method using the helicopter's own tilt during flight to

151
00:09:57.240 --> 00:10:00.960
calculate wind speeds. Just as a drone on Earth needs

152
00:10:01.000 --> 00:10:04.519
to tilt into the wind to maintain its position, Ingenuity's

153
00:10:04.600 --> 00:10:09.799
tilt measurements provided crucial data about Mars's atmospheric conditions. These

154
00:10:09.840 --> 00:10:13.960
findings are particularly valuable for future Mars missions, especially as

155
00:10:13.960 --> 00:10:17.320
we plan more aerial vehicles like the upcoming Dragonfly mission

156
00:10:17.360 --> 00:10:21.559
to Saturn's moon Titan. Understanding these wind patterns is crucial

157
00:10:21.600 --> 00:10:25.399
for designing spacecraft and planning missions that can safely navigate

158
00:10:25.440 --> 00:10:32.440
alien atmospheres. Finally today, looking into the future, exciting developments

159
00:10:32.440 --> 00:10:35.399
are on the horizon as the Vera Sea Reuben Observatory

160
00:10:35.440 --> 00:10:38.600
prepares to begin its operations from its home atop Sarah

161
00:10:38.600 --> 00:10:42.240
Paschan in Chile. This cutting edge facility is about to

162
00:10:42.279 --> 00:10:45.279
embark on an ambitious ten year survey that promises to

163
00:10:45.399 --> 00:10:49.279
revolutionize our understanding of the cosmos, particularly when it comes

164
00:10:49.360 --> 00:10:53.919
to exploding stars. Scientists predict the observatory will detect millions

165
00:10:53.960 --> 00:10:58.320
of what are playfully nicknamed vampire stars, white dwarfs that

166
00:10:58.399 --> 00:11:01.679
steal material from their companion stars until they explode in

167
00:11:01.759 --> 00:11:06.360
spectacular fashion. These explosions, known as Type I as supernovas,

168
00:11:06.639 --> 00:11:09.879
are particularly valuable to astronomers because they always release the

169
00:11:09.879 --> 00:11:13.240
same amount of light, making them perfect cosmic measuring sticks.

170
00:11:14.120 --> 00:11:17.840
Think of these supernovas as celestial lampposts. If you know

171
00:11:17.879 --> 00:11:20.519
how bright they should be, you can figure out how

172
00:11:20.559 --> 00:11:23.679
far away they are by how dim they appear. This

173
00:11:23.840 --> 00:11:27.320
makes them crucial tools for understanding how our universe is

174
00:11:27.360 --> 00:11:31.919
expanding and the mysterious force behind this expansion, dark energy.

175
00:11:32.480 --> 00:11:36.000
The observatory will scan the entire Southern sky every few nights,

176
00:11:36.360 --> 00:11:41.159
giving astronomers unprecedented opportunities to catch these stellar explosions in action.

177
00:11:42.039 --> 00:11:44.919
It's expected to generate a staggering amount of data, up

178
00:11:45.000 --> 00:11:47.799
to ten million alerts embedded in twenty terabytes of information

179
00:11:47.879 --> 00:11:51.159
every single night. This wealth of data could help resolve

180
00:11:51.200 --> 00:11:54.559
some pressing questions about dark energy, which makes up about

181
00:11:54.600 --> 00:11:58.879
sixty eight percent of our universe's energy budget. Recent observations

182
00:11:58.879 --> 00:12:02.000
have suggested that dark energy strength might not be constant

183
00:12:02.000 --> 00:12:06.159
as previously thought, and the Reuben Observatory's observations could finally

184
00:12:06.200 --> 00:12:10.159
help us understand if and how this mysterious force is

185
00:12:10.240 --> 00:12:14.519
changing over time. This new era of observation represents a

186
00:12:14.600 --> 00:12:18.840
fundamental shift in how we study the cosmos. The sheer

187
00:12:18.919 --> 00:12:22.200
volume of data will require new methods of analysis, setting

188
00:12:22.200 --> 00:12:25.799
the stage for the next generation of astronomical discoveries and

189
00:12:25.840 --> 00:12:30.679
our understanding of the Universe's ultimate fate. And with that

190
00:12:30.759 --> 00:12:34.279
we wrap up today's fascinating journey through the Cosmos. Thank
