surprising findings from the James Webb Space Telescope about early galaxies,

11
00:00:38.039 --> 00:00:41.039
and catch up with NASA's Parker Solar Probe as it

12
00:00:41.079 --> 00:00:44.240
continues its close encounters with our son. So buckle up

13
00:00:44.280 --> 00:00:46.240
and get ready for a journey through the cosmos as

14
00:00:46.280 --> 00:00:49.359
we explore these fascinating stories from the world of astronomy

15
00:00:49.399 --> 00:00:54.119
and space science. United Launch Alliance's second Vulcan rocket flight

16
00:00:54.200 --> 00:00:57.000
took off last Friday, marking a crucial test in the

17
00:00:57.000 --> 00:01:00.079
company's efforts to certify the new launcher for high priority

18
00:01:00.159 --> 00:01:04.120
national security missions. While the rocket successfully reached orbit. The

19
00:01:04.120 --> 00:01:07.519
flight wasn't without drama. One of the two solid propellants

20
00:01:07.519 --> 00:01:11.319
strap on boosters, experienced an anomaly during the ascent. About

21
00:01:11.319 --> 00:01:14.599
thirty seven seconds after liftoff, observers noticed a shower of

22
00:01:14.640 --> 00:01:17.640
sparks and what appeared to be debris falling away from

23
00:01:17.640 --> 00:01:20.519
the right side booster. The issue seemed to originate near

24
00:01:20.560 --> 00:01:23.239
the nozzle at the base of the booster, causing a

25
00:01:23.319 --> 00:01:27.120
noticeable change in the exhaust plumes shape. Despite this setback,

26
00:01:27.159 --> 00:01:31.120
the vulcan continued its climb to space, demonstrating impressive resilience.

27
00:01:31.560 --> 00:01:34.519
The core stage's two Blue Origin built B four engines,

28
00:01:34.599 --> 00:01:38.200
each generating five hundred fifty thousand pounds of thrust, carried

29
00:01:38.239 --> 00:01:41.560
on with the mission. After the first stage separation, the

30
00:01:41.560 --> 00:01:45.239
Centaur upper stage took over, completing two burns to demonstrate

31
00:01:45.319 --> 00:01:48.599
its ability to restart in space, a key requirement for

32
00:01:48.640 --> 00:01:54.359
complex military payload trajectories. ULA CEO Tory Bruno acknowledged the

33
00:01:54.400 --> 00:01:58.480
booster anomaly, but emphasized that the overall trajectory remained nominal

34
00:01:58.519 --> 00:02:01.879
throughout the flight, Any plans to investigate the issue thoroughly

35
00:02:01.959 --> 00:02:05.040
once the mission is complete. This flight was the second

36
00:02:05.040 --> 00:02:08.479
of two certification test flights needed before the Vulcan can

37
00:02:08.520 --> 00:02:11.639
carry high priority payloads for the US Space Force and

38
00:02:11.759 --> 00:02:15.400
National Reconnaissance Office. The impact of the booster anomaly on

39
00:02:15.439 --> 00:02:19.280
the certification process remains uncertain, but it's clear that ULA

40
00:02:19.360 --> 00:02:22.319
will need to address any concerns before moving forward with

41
00:02:22.439 --> 00:02:26.280
national security launches. The Vulcan represents the future of ULA,

42
00:02:26.759 --> 00:02:29.879
set to replace both the retired Delta four and the

43
00:02:29.879 --> 00:02:32.680
soon to be phased out at Las five rockets. With

44
00:02:32.800 --> 00:02:36.240
over seventy missions already booked before its first flight, the

45
00:02:36.280 --> 00:02:39.520
stakes are high for ULA to resolve any issues quickly

46
00:02:39.840 --> 00:02:44.000
and maintain customer confidence in the new launch system. Now,

47
00:02:44.080 --> 00:02:46.800
let's turn our attention to a fascinating discovery made by

48
00:02:46.800 --> 00:02:50.759
the Hubble Space Telescope. The Venerable Observatory has captured an

49
00:02:50.800 --> 00:02:53.280
image of a galaxy that's breaking the mold when it

50
00:02:53.319 --> 00:02:57.400
comes to classification. Located about fifty four million light years

51
00:02:57.400 --> 00:03:01.520
away in the Virgo galaxy cluster GGC four thousand, six

52
00:03:01.599 --> 00:03:05.800
hundred and ninety four is what astronomers call a peculiar galaxy.

53
00:03:06.240 --> 00:03:08.759
At first glance, it appears to have characteristics of both

54
00:03:08.840 --> 00:03:12.759
elliptical and spiral galaxies. Making it a real cosmic oddball.

55
00:03:13.400 --> 00:03:16.120
NGC four thousand, six hundred and ninety four has a

56
00:03:16.159 --> 00:03:19.439
smooth looking, armless disc that's nearly devoid of star formation,

57
00:03:20.039 --> 00:03:23.719
similar to an elliptical galaxy. However, its stellar population is

58
00:03:23.719 --> 00:03:26.840
still relatively young and new stars are actively forming in

59
00:03:26.879 --> 00:03:30.199
its core. This gives NGC four thousand, six hundred and

60
00:03:30.319 --> 00:03:34.080
ninety four a markedly different stellar profile from a classic

61
00:03:34.159 --> 00:03:38.199
elliptical galaxy. What's even more intriguing is the chaotic structure

62
00:03:38.240 --> 00:03:41.159
of dust visible in the hubble image. This indicates some

63
00:03:41.240 --> 00:03:44.439
kind of disturbance in the galaxy's past. As it turns out,

64
00:03:44.599 --> 00:03:47.639
NGC four thousand, six hundred and ninety four has undergone

65
00:03:47.680 --> 00:03:51.439
a violent collision with a nearby dwarf galaxy VCC twenty

66
00:03:51.479 --> 00:03:55.080
sixty two. This cosmic crash has left NGC four thousand,

67
00:03:55.159 --> 00:03:58.240
six hundred and ninety four accreting gas from its smaller neighbor,

68
00:03:58.680 --> 00:04:04.280
fueling its unique character. Teruristics. Astronomers classify NGC four thousand,

69
00:04:04.360 --> 00:04:07.800
six hundred and ninety four as a lenticular galaxy, a

70
00:04:07.879 --> 00:04:10.400
type that lacks the distinct spiral arms but still has

71
00:04:10.439 --> 00:04:14.039
a central bulge and disc. These galactic oddballs are crucial

72
00:04:14.039 --> 00:04:17.600
for understanding how galaxies evolve over time. The discovery of

73
00:04:17.800 --> 00:04:21.000
NGC four thousand, six hundred and ninety four reminds us

74
00:04:21.040 --> 00:04:24.319
that the universe is full of surprises and not everything

75
00:04:24.360 --> 00:04:27.879
fits neatly into our pre defined categories. By studying these

76
00:04:27.920 --> 00:04:32.000
peculiar galaxies, astronomers can gain valuable insights into the complex

77
00:04:32.079 --> 00:04:36.720
processes that shape our cosmic neighborhood. Let's get an update

78
00:04:36.759 --> 00:04:39.879
now from Blue Origin, who've been far from taking things easy.

79
00:04:40.360 --> 00:04:43.519
Blue Origin, the aerospace company founded by Amazon's Jeff Bezos,

80
00:04:43.560 --> 00:04:47.040
is gearing up for an exciting milestone this Monday, October seventh.

81
00:04:47.120 --> 00:04:49.720
They're set to debut a brand new spacecraft on their

82
00:04:49.839 --> 00:04:53.439
NS twenty seven mission. This uncrude flight will mark the

83
00:04:53.480 --> 00:04:56.879
first launch for this particular New Shepherd vehicle. The mission

84
00:04:56.920 --> 00:04:59.519
is scheduled to lift off from Blue Origins West Texas

85
00:04:59.519 --> 00:05:02.399
site during a window that opens at nine am Eastern time.

86
00:05:02.879 --> 00:05:05.639
While no humans will be on board, the capsule will

87
00:05:05.639 --> 00:05:09.839
carry twelve research payloads, including new navigation systems for both

88
00:05:09.920 --> 00:05:13.600
New Shepherd and Blue Origin's larger New Glen rocket. This

89
00:05:13.639 --> 00:05:17.000
new vehicle features some notable upgrades. Blue Origin says It

90
00:05:17.040 --> 00:05:21.600
includes technology improvements to enhance performance and reusability, as well

91
00:05:21.639 --> 00:05:25.000
as an updated exterior design. The company also mentions that

92
00:05:25.040 --> 00:05:28.680
it has accommodations for payloads on the booster itself. The

93
00:05:28.800 --> 00:05:31.560
NS twenty seven mission represents an important step for Blue

94
00:05:31.560 --> 00:05:35.399
Origins commercial space flight ambitions. It's the second human rated

95
00:05:35.439 --> 00:05:38.480
New Shepherd vehicle, which should allow the company to increase

96
00:05:38.519 --> 00:05:42.120
its flight capacity and better meet growing customer demand for

97
00:05:42.160 --> 00:05:47.000
suborbital space tourism and research flights. If successful, this launch

98
00:05:47.040 --> 00:05:49.399
will pave the way for Blue Origin to expand its

99
00:05:49.439 --> 00:05:52.959
operations and potentially increase the frequency of its crude flights

100
00:05:53.000 --> 00:05:55.600
in the future. It's a clear sign that the company

101
00:05:55.680 --> 00:06:00.279
is pushing forward in the competitive commercial space industry. Moving

102
00:06:00.279 --> 00:06:04.439
on now to a NASA mission update. NASA's exoplanet hunting spacecraft,

103
00:06:04.839 --> 00:06:09.000
the Transiting Exoplanet Survey Satellite or TESTS, has made a

104
00:06:09.000 --> 00:06:12.160
groundbreaking discovery that's pushing the boundaries of what we thought

105
00:06:12.160 --> 00:06:16.240
possible in stellar systems. Scientists have spotted a record breaking

106
00:06:16.319 --> 00:06:19.600
triple star system that's so tightly packed it could fit

107
00:06:19.680 --> 00:06:23.240
comfortably between our Sun and its closest planet, Mercury. This

108
00:06:23.360 --> 00:06:26.199
extraordinary system, known as TICK two, nine zero zero six

109
00:06:26.240 --> 00:06:28.920
one four eight four is located about five thousand light

110
00:06:29.000 --> 00:06:32.199
years away in the constellation Sickness. It consists of twin

111
00:06:32.279 --> 00:06:35.120
stars that orbit each other every one point eight earth days,

112
00:06:35.439 --> 00:06:38.360
with a third star circling this pair every twenty five days.

113
00:06:38.720 --> 00:06:41.920
To put this in perspective, the previous record holder for

114
00:06:42.000 --> 00:06:44.519
the tightest three star system had an outer orbit of

115
00:06:44.560 --> 00:06:48.120
thirty three days, set back in nineteen fifty six. What

116
00:06:48.279 --> 00:06:51.360
makes this discovery even more remarkable is the stability of

117
00:06:51.360 --> 00:06:54.480
the system. The stars orbit in nearly the same plane,

118
00:06:54.720 --> 00:06:58.639
which helps maintain their gravitational balance. However, this delicate dance

119
00:06:58.639 --> 00:07:01.279
won't last forever. In a few million years, the twin

120
00:07:01.319 --> 00:07:03.759
stars at the heart of the system will expand and

121
00:07:03.839 --> 00:07:09.160
eventually merge, triggering a massive supernova explosion. This finding isn't

122
00:07:09.160 --> 00:07:12.399
just a cosmic curiosity. It has significant implications for our

123
00:07:12.480 --> 00:07:16.319
understanding of star formation and evolution. The compact nature of

124
00:07:16.360 --> 00:07:20.000
the system suggests that these stars likely form together from

125
00:07:20.040 --> 00:07:23.720
the same process, challenging our models of how multiple star

126
00:07:23.800 --> 00:07:27.040
systems come into being. The discovery was made possible through

127
00:07:27.079 --> 00:07:30.959
a combination of test data, machine learning algorithms, and the

128
00:07:31.040 --> 00:07:34.480
keen eyes of citizens scientists. It highlights the power of

129
00:07:34.519 --> 00:07:38.839
collaborative efforts between professional astronomers and amateur enthusiasts in pushing

130
00:07:38.879 --> 00:07:43.600
the boundaries of astronomical research. Looking ahead, NASA's upcoming Nancy

131
00:07:43.639 --> 00:07:47.360
Grace Roman Space Telescope, set to launch in twenty twenty seven,

132
00:07:47.839 --> 00:07:51.720
promises to reveal even more of these tightly packed star systems.

133
00:07:52.240 --> 00:07:55.839
With its superior resolution, Roman could potentially help us discover

134
00:07:55.959 --> 00:07:59.439
systems with even shorter orbits, or perhaps even more stars

135
00:07:59.439 --> 00:08:03.360
crammed into a single system. This record breaking triple star

136
00:08:03.439 --> 00:08:06.519
system serves as a reminder that the universe still has

137
00:08:06.600 --> 00:08:10.319
plenty of surprises in store for us, continually challenging and

138
00:08:10.360 --> 00:08:15.319
expanding our understanding of the cosmos. Speaking of discoveries, here's

139
00:08:15.360 --> 00:08:17.959
another one from an old friend. The James Web Space

140
00:08:18.000 --> 00:08:22.560
Telescope continues to astound scientists with its groundbreaking discoveries. Recent

141
00:08:22.600 --> 00:08:26.199
observations have unveiled surprisingly bright and mature galaxies in the

142
00:08:26.279 --> 00:08:31.600
early universe, challenging our existing models of galaxy formation and cosmology.

143
00:08:31.680 --> 00:08:35.080
These ancient galaxies, observed just three hundred million years after

144
00:08:35.120 --> 00:08:39.000
the Big Bang, are far more luminous than scientists anticipated.

145
00:08:39.320 --> 00:08:42.159
Their brightness suggests they contain more stars in mass than

146
00:08:42.200 --> 00:08:46.120
previously thought possible for such young cosmic objects. What's even

147
00:08:46.159 --> 00:08:49.559
more intriguing is that many of these early galaxies show

148
00:08:49.720 --> 00:08:53.600
signs of actively growing black holes at their centers, another

149
00:08:53.639 --> 00:08:57.960
indication of their unexpectedly rapid maturation. These findings have left

150
00:08:58.000 --> 00:09:01.480
astronomers scratching their heads. How could these galaxies have formed

151
00:09:01.519 --> 00:09:03.879
so quickly and become so bright in such a short

152
00:09:03.879 --> 00:09:07.240
time after the universe's birth. It's a puzzle that's forcing

153
00:09:07.320 --> 00:09:11.320
us to reconsider our understanding of early galaxy evolution. Some

154
00:09:11.440 --> 00:09:14.559
scientists propose that star formation in the early universe may

155
00:09:14.600 --> 00:09:18.279
have been more intense or bursty than we previously believed.

156
00:09:18.679 --> 00:09:22.120
Others suggest factors like lower amounts of galactic dust or

157
00:09:22.120 --> 00:09:26.120
a different distribution of star masses could explain the unexpected brightness.

158
00:09:26.519 --> 00:09:30.360
But these observations aren't just challenging our ideas about galaxy formation.

159
00:09:30.840 --> 00:09:34.039
They're also prompting some researchers to consider modifications to our

160
00:09:34.080 --> 00:09:38.399
broader cosmological theories. Some have even suggested that these findings

161
00:09:38.440 --> 00:09:42.600
might require us to reconsider the age of the universe itself. However,

162
00:09:42.639 --> 00:09:45.360
it's important to note that before we start rewriting our

163
00:09:45.399 --> 00:09:49.279
cosmology textbooks. We need a more detailed understanding of the

164
00:09:49.320 --> 00:09:53.080
physical processes at work in these early galaxies. As we

165
00:09:53.159 --> 00:09:56.039
continue to gather data and refine our models, we may

166
00:09:56.039 --> 00:09:59.320
find explanations that fit within our current framework of understanding.

167
00:10:00.360 --> 00:10:03.240
What's clear is that the James Web Space Telescope is

168
00:10:03.279 --> 00:10:06.240
living up to its promise of revolutionizing our view of

169
00:10:06.279 --> 00:10:09.279
the early universe. As we peer further back in time,

170
00:10:09.679 --> 00:10:12.120
we're sure to encounter more surprises that will push the

171
00:10:12.120 --> 00:10:15.639
boundaries of our knowledge and spark new questions about the cosmos.

172
00:10:17.080 --> 00:10:20.879
And finally, today, another NASA record breaking update. NASA's Parker

173
00:10:20.919 --> 00:10:23.639
Solar Probe has once again pushed the boundaries of solar

174
00:10:23.679 --> 00:10:26.960
exploration with its latest close encounter with our star. On

175
00:10:27.000 --> 00:10:30.799
September thirtieth, the probe completed its twenty first close approach

176
00:10:30.840 --> 00:10:34.240
to the Sun, matching its own impressive distance record by

177
00:10:34.240 --> 00:10:36.759
coming within just four point five to one million miles

178
00:10:36.799 --> 00:10:40.240
of the solar surface. During this close approach, or perihelion,

179
00:10:40.639 --> 00:10:43.440
the spacecraft reached speeds of nearly three hundred and ninety

180
00:10:43.440 --> 00:10:46.000
five thousand miles per hour as it raced around the Sun.

181
00:10:46.600 --> 00:10:49.600
This mind boggling velocity is about one hundred and eighty

182
00:10:49.639 --> 00:10:52.559
times faster than the speed of a typical commercial airliner.

183
00:10:53.200 --> 00:10:56.000
But the Parker Solar Probe isn't done breaking records yet.

184
00:10:56.279 --> 00:10:58.720
After a fly by a venus in November, which will

185
00:10:58.799 --> 00:11:02.039
use the planet's gravity to adjust the probe's trajectory, it

186
00:11:02.039 --> 00:11:04.360
will make an even closer approach to the Sun on

187
00:11:04.440 --> 00:11:08.080
December twenty fourth. This upcoming encounter will bring the spacecraft

188
00:11:08.159 --> 00:11:10.559
within a mere three point eight million miles of the

189
00:11:10.600 --> 00:11:14.960
Solar surface, traveling at speeds around four hundred thirty thousand

190
00:11:14.960 --> 00:11:19.279
miles per hour. These incredibly close passes allow scientists to

191
00:11:19.320 --> 00:11:23.399
gather unprecedented data about the Sun's atmosphere, magnetic fields, and

192
00:11:23.440 --> 00:11:26.799
the solar wind. The information collected by the Parker Solar

193
00:11:26.799 --> 00:11:29.720
Probe is helping us better understand our star and its

194
00:11:29.720 --> 00:11:32.960
effects on space weather, which can impact technology both in

195
00:11:33.080 --> 00:11:37.000
orbit and on Earth. And that brings us to the

196
00:11:37.080 --> 00:11:40.840
end of today's journey through the cosmos. From record breaking

197
00:11:40.879 --> 00:11:45.080
star systems to mysterious early galaxies, the universe never fails

198
00:11:45.120 --> 00:11:48.320
to amaze and inspire us. I'm Anna, and I hope
