1
00:00:00.200 --> 00:00:03.359
Welcome to Astronomy Daily, your daily dose of space and

2
00:00:03.399 --> 00:00:06.559
astronomy news. I'm your host, Anna, and today we've got

3
00:00:06.599 --> 00:00:10.679
a packed episode, covering everything from stranded astronauts finally coming home,

4
00:00:10.960 --> 00:00:16.440
to groundbreaking telescope observations and exciting space launches. From mission

5
00:00:16.480 --> 00:00:20.000
control to the depths of deep space. We're bringing you

6
00:00:20.079 --> 00:00:24.679
the latest developments in space exploration and astronomical discoveries that

7
00:00:24.719 --> 00:00:27.920
are shaping our understanding of the Cosmos. Let's get on

8
00:00:28.000 --> 00:00:32.359
with it. After an unexpectedly extended stay aboard the International

9
00:00:32.439 --> 00:00:36.600
Space Station, NASA astronauts Butch Wilmore and Sunny Williams are

10
00:00:36.640 --> 00:00:40.399
finally preparing to return home. What was originally planned as

11
00:00:40.439 --> 00:00:43.600
an eight day mission has stretched into nearly three hundred

12
00:00:43.679 --> 00:00:47.240
days in space, making this one of the longer unplanned

13
00:00:47.280 --> 00:00:51.079
extensions of a space mission in recent memory. The two

14
00:00:51.119 --> 00:00:54.479
astronauts arrived at the ISS last June as part of

15
00:00:54.479 --> 00:00:58.439
Boeing's first Starliner crew test flight. However, their return was

16
00:00:58.479 --> 00:01:02.399
delayed due to multiple technical issues with Boeing spacecraft, including

17
00:01:02.439 --> 00:01:05.799
five helium leaks and five failures of its reaction control

18
00:01:05.840 --> 00:01:09.719
system thrusters. These complications led to the mission being abandoned,

19
00:01:09.840 --> 00:01:13.959
leaving Wilmore and Williams to wait for an alternative ride home. Now,

20
00:01:14.079 --> 00:01:16.680
they're scheduled to depart the space station aboard a SpaceX

21
00:01:16.760 --> 00:01:20.120
Dragon capsule on Tuesday morning, with a planned splashed down

22
00:01:20.120 --> 00:01:23.519
near Florida by evening. They'll be joined by NASA astronaut

23
00:01:23.599 --> 00:01:28.400
Nick Haig and Roscosmos cosmonaut Alexander Gorbanov in the Dragon capsule,

24
00:01:28.719 --> 00:01:34.239
appropriately named Freedom. During their extended stay, the astronauts have

25
00:01:34.280 --> 00:01:37.519
had to maintain rigorous health protocols to combat the effects

26
00:01:37.599 --> 00:01:41.400
of long term spaceflight. This includes two hours of daily

27
00:01:41.480 --> 00:01:44.879
resistance and endurance training to prevent the muscle and bone

28
00:01:44.920 --> 00:01:49.159
loss that naturally occurs in microgravity. While there three hundred

29
00:01:49.200 --> 00:01:52.000
days in space is impressive, it's still well short of

30
00:01:52.040 --> 00:01:54.879
the current record of four hundred and thirty seven days

31
00:01:54.920 --> 00:01:58.680
set by Russian cosmonaut Valeri Polyakov in nineteen ninety five.

32
00:01:59.439 --> 00:02:03.120
NASA will be live streaming the entire return journey, starting

33
00:02:03.159 --> 00:02:05.959
with the hatch closure between Freedom and the ISS on

34
00:02:06.040 --> 00:02:09.759
Monday night. The undocking is scheduled for early Tuesday morning,

35
00:02:09.800 --> 00:02:12.719
North American time, with the final phase of re entry

36
00:02:12.719 --> 00:02:17.360
beginning Tuesday evening. Weather conditions are currently favorable for the splashdown,

37
00:02:17.719 --> 00:02:22.280
though NASA continues to monitor various factors including spacecraft readiness, recovery,

38
00:02:22.280 --> 00:02:27.759
team preparedness, and sea states. Meanwhile, in Australia, in a

39
00:02:27.800 --> 00:02:31.639
remarkable achievement for radio astronomy, the SCAYE Low telescope in

40
00:02:31.680 --> 00:02:34.719
remote Australia has captured its first image of the Cosmos.

41
00:02:35.120 --> 00:02:39.000
While construction of this groundbreaking instrument is still ongoing, even

42
00:02:39.000 --> 00:02:43.199
its initial capabilities have revealed something extraordinary. Eighty five of

43
00:02:43.280 --> 00:02:46.080
the brightest known galaxies in a particular region of space,

44
00:02:46.560 --> 00:02:50.120
each harboring super massive black holes at their centers. To

45
00:02:50.159 --> 00:02:53.560
put the scale of this observation in perspective, the area

46
00:02:53.599 --> 00:02:56.319
of sky captured is equivalent to holding a small apple

47
00:02:56.360 --> 00:03:00.159
at arm's length, or about one hundred full moons. What

48
00:03:00.240 --> 00:03:02.960
makes this achievement even more impressive is that it was

49
00:03:03.000 --> 00:03:07.439
accomplished using just four connected stations comprising only one thousand,

50
00:03:07.599 --> 00:03:12.120
twenty four antennas spread across less than six kilometers. Doctor

51
00:03:12.199 --> 00:03:17.319
George Heald, the skaa Low lead commissioning scientist, notes that

52
00:03:17.360 --> 00:03:21.400
the quality of this first image exceeded their expectations even

53
00:03:21.439 --> 00:03:25.080
with such an early version of the telescope. The successful

54
00:03:25.120 --> 00:03:28.479
image also confirmed that the telescope's complex systems are working

55
00:03:28.479 --> 00:03:31.759
as intended, from the proper connection of stations to the

56
00:03:31.800 --> 00:03:35.960
crucial timing systems and data calibration processes. But this is

57
00:03:36.120 --> 00:03:39.560
just the beginning. Over the next eighteen months, an additional

58
00:03:39.599 --> 00:03:42.759
sixteen thousand antennas will be added to the array, making

59
00:03:42.800 --> 00:03:45.840
Sky low the most sensitive radio telescope of its kind.

60
00:03:46.280 --> 00:03:49.479
With this expanded capability, it will be able to detect

61
00:03:49.560 --> 00:03:52.639
more than four thousand, five hundred galaxies in the same

62
00:03:52.759 --> 00:03:56.759
area of sky that currently shows just eighty five. The

63
00:03:56.879 --> 00:04:01.000
ultimate vision is even more ambitious. Once construt production is completed,

64
00:04:01.319 --> 00:04:04.199
Scale low will include more than one hundred thirty thousand

65
00:04:04.240 --> 00:04:08.759
antennas spread across seventy four kilometers. When it begins deep

66
00:04:08.800 --> 00:04:12.319
surveys of this region of sky in twenty thirty, scientists

67
00:04:12.319 --> 00:04:15.479
expect it to reveal up to six hundred thousand galaxies,

68
00:04:15.960 --> 00:04:18.920
including some of the faintest and most distant objects from

69
00:04:18.959 --> 00:04:22.120
the early universe, when the first stars and galaxies were

70
00:04:22.160 --> 00:04:25.079
just beginning to form. Let's move on now to this

71
00:04:25.120 --> 00:04:28.759
week's activity schedule. Space launch enthusiasts are in for an

72
00:04:28.759 --> 00:04:32.600
exciting week ahead with multiple missions scheduled from several launch

73
00:04:32.600 --> 00:04:36.000
providers around the globe. Let's break down the packed launch

74
00:04:36.120 --> 00:04:39.680
manifest that's coming our way. SpaceX is leading the charge

75
00:04:39.720 --> 00:04:43.160
with three Falcon nine launches on the schedule. First up

76
00:04:43.199 --> 00:04:46.480
is a Starlink mission set for Tuesday, launching from Cape

77
00:04:46.480 --> 00:04:50.120
Canaveral Space Force Station in Florida. This will be followed

78
00:04:50.160 --> 00:04:53.959
by a National Reconnaissance Office mission from Vandenberg Space Force

79
00:04:53.959 --> 00:04:57.439
Space in California on Wednesday. The week will wrap up

80
00:04:57.480 --> 00:05:01.759
with another Starlink launch from Vandenberg on Saturday. Rocket Lab

81
00:05:01.800 --> 00:05:05.360
is maintaining its impressive launch cadence with an electron mission

82
00:05:05.439 --> 00:05:09.199
dubbed High five from their launch site in New Zealand.

83
00:05:09.959 --> 00:05:13.439
This mission, launching early Tuesday, will deliver the final batch

84
00:05:13.439 --> 00:05:17.560
of satellites for the French company Kinis, completing their Internet

85
00:05:17.560 --> 00:05:21.560
of Things constellation. This launch comes just seventy two hours

86
00:05:21.600 --> 00:05:26.319
after their previous successful mission, showcasing Rocket labs growing capability

87
00:05:26.360 --> 00:05:31.360
for rapid launch operations. Meanwhile, in China, Galactic Energy has

88
00:05:31.360 --> 00:05:34.959
scheduled two launches of their Goushen Singh one rocket from

89
00:05:35.000 --> 00:05:38.560
the Juquan Satellite Launch Center in the Gobi Desert. The

90
00:05:38.600 --> 00:05:42.399
first mission has already successfully delivered eight satellites to orbit,

91
00:05:42.839 --> 00:05:47.439
including Earth observation and weather monitoring spacecraft. A second launch

92
00:05:47.480 --> 00:05:49.839
is planned for later in the week, though details about

93
00:05:49.839 --> 00:05:53.959
its payload remain under wraps. This busy launch schedule continues

94
00:05:54.000 --> 00:05:56.399
the trend we've seen in recent months of increased commercial

95
00:05:56.399 --> 00:05:59.839
space activity. If all launches precede as planned, we'll see

96
00:06:00.360 --> 00:06:03.800
orbital missions in just one week, further demonstrating the growing

97
00:06:03.839 --> 00:06:09.680
accessibility and commercialization of space launch services. Next up, it's

98
00:06:09.759 --> 00:06:11.959
nice to be reporting on a highly successful mission to

99
00:06:12.000 --> 00:06:16.199
the Moon. In a significant milestone for commercial lunar exploration,

100
00:06:16.720 --> 00:06:20.360
Firefly Aerospace has announced the successful completion of their Blue

101
00:06:20.360 --> 00:06:24.439
ghost Ie lunar lander mission. The spacecraft wrapped up operations

102
00:06:24.480 --> 00:06:26.800
after an impressive three hundred and forty six hours of

103
00:06:26.879 --> 00:06:30.720
daytime operations plus an additional five hours after sunset at

104
00:06:30.759 --> 00:06:34.560
its landing site in mare Crisium. During its mission, Blue

105
00:06:34.560 --> 00:06:38.720
ghost Ie exceeded expectations, collecting over one hundred and nineteen

106
00:06:38.720 --> 00:06:42.399
gigabytes of data, including fifty one gigabytes of scientific and

107
00:06:42.399 --> 00:06:47.279
technical information from its ten NASA sponsored payloads. The mission

108
00:06:47.319 --> 00:06:50.439
achieved all of its objectives, marking a major success for

109
00:06:50.480 --> 00:06:55.600
both Firefly and NASA's Commercial Lunar Payload Services Program. Among

110
00:06:55.639 --> 00:06:59.600
its achievements, the lander made history by tracking GPS signals

111
00:06:59.600 --> 00:07:02.720
on the lunce for the first time, and conducted the

112
00:07:02.800 --> 00:07:07.360
deepest robotic drilling operation ever performed on the Moon. The

113
00:07:07.399 --> 00:07:11.240
spacecraft even managed to capture observations of a solar eclipse

114
00:07:11.519 --> 00:07:14.279
as Earth passed between the Sun and the Moon on

115
00:07:14.360 --> 00:07:18.360
March fourteenth, creating a spectacular ring of light as sunlight

116
00:07:18.439 --> 00:07:23.720
filtered through Earth's atmosphere. The mission's success is particularly noteworthy

117
00:07:24.120 --> 00:07:26.920
as it was Firefly's first attempt at a lunar landing.

118
00:07:27.920 --> 00:07:31.839
This achievement stands out even more considering the challenges faced

119
00:07:31.839 --> 00:07:35.560
by other recent commercial lunar missions that either failed to

120
00:07:35.600 --> 00:07:38.920
reach the Moon or experienced hard landings that limited their

121
00:07:38.959 --> 00:07:43.800
capabilities Looking ahead, Firefly already has two more lunar missions

122
00:07:43.800 --> 00:07:47.240
in the pipeline through NASA's program. Blue Ghost two is

123
00:07:47.279 --> 00:07:50.319
scheduled for launch next year and will attempt an ambitious

124
00:07:50.360 --> 00:07:53.199
landing on the lunar far side, while Blue GHOSTS three

125
00:07:53.319 --> 00:07:56.160
is planned for twenty twenty eight, returning to the near

126
00:07:56.279 --> 00:07:59.720
side with a suite of astrophysical and lunar science instruments,

127
00:08:00.160 --> 00:08:04.439
including a small rover. This successful mission represents a significant

128
00:08:04.439 --> 00:08:08.959
step forward improving the viability of commercial lunar exploration and

129
00:08:09.040 --> 00:08:12.199
sets a promising precedent for future private sector missions to

130
00:08:12.240 --> 00:08:16.639
the Moon. The James Web Space Telescope has achieved another

131
00:08:16.759 --> 00:08:20.680
remarkable milestone by capturing the first ever direct images of

132
00:08:20.720 --> 00:08:24.800
carbon dioxide in the atmosphere of a distant planet. These

133
00:08:24.839 --> 00:08:29.160
groundbreaking observations come from the HR eight thousand, seven hundred

134
00:08:29.199 --> 00:08:32.279
and ninety nine system, located one hundred and thirty light

135
00:08:32.360 --> 00:08:37.000
years from Earth, and provide crucial insights into how planets form.

136
00:08:37.279 --> 00:08:41.080
The discovery is particularly significant as it offers compelling evidence

137
00:08:41.120 --> 00:08:43.879
that the four giant planets in the HR eight thousand,

138
00:08:44.000 --> 00:08:47.240
seven hundred and ninety nine system likely formed through the

139
00:08:47.279 --> 00:08:51.080
same process as our own Jupiter and Saturn, through core accretion,

140
00:08:51.279 --> 00:08:55.879
where solid cores gradually accumulate gas over time. This finding

141
00:08:55.960 --> 00:09:00.759
demonstrates Web's unprecedented capability to directly analyze the chemical composition

142
00:09:00.879 --> 00:09:04.879
of exoplanet atmospheres, rather than just inferring it from starlight.

143
00:09:05.840 --> 00:09:08.840
The HR eight thousan, seven hundred and ninety nine system

144
00:09:08.879 --> 00:09:12.519
is remarkably young, only about thirty million years old compared

145
00:09:12.559 --> 00:09:15.919
to our Solar system's four point six billion years. The

146
00:09:16.000 --> 00:09:20.080
planets are still hot from their formation, emitting significant infrared

147
00:09:20.159 --> 00:09:23.480
light that provides scientists with valuable data about their composition

148
00:09:23.559 --> 00:09:28.559
and formation process. Using web's advanced coronagraphs, which block the

149
00:09:28.600 --> 00:09:31.600
bright light from stars similar to how a solar eclipse works,

150
00:09:32.240 --> 00:09:35.039
the research team was able to detect more heavy elements

151
00:09:35.080 --> 00:09:39.720
in these planets than previously thought. They observed specific wavelengths

152
00:09:39.720 --> 00:09:43.639
that reveal the presence of various gases and other atmospheric components.

153
00:09:44.720 --> 00:09:48.440
This achievement builds upon web's earlier indirect detection of carbon

154
00:09:48.480 --> 00:09:52.320
dioxide in twenty twenty two, when it observed the exoplanet

155
00:09:52.679 --> 00:09:55.360
WASP thirty nine B as it passed in front of

156
00:09:55.399 --> 00:09:59.519
its star. But this new direct imaging capability opens up

157
00:09:59.559 --> 00:10:03.799
exciting new possibilities for studying distant worlds and understanding how

158
00:10:03.840 --> 00:10:08.440
planetary systems form and evolve. The findings not only advance

159
00:10:08.480 --> 00:10:12.480
our understanding of planet formation, but also demonstrate web's remarkable

160
00:10:12.519 --> 00:10:16.080
ability to peer into the atmospheres of distant worlds with

161
00:10:16.240 --> 00:10:20.559
unprecedented detail and precision. This capability will be crucial as

162
00:10:20.600 --> 00:10:23.960
we continue to search for and study potentially habitable planets

163
00:10:24.000 --> 00:10:27.919
beyond our Solar system. Let's turn our attention now to

164
00:10:28.000 --> 00:10:32.440
a fascinating stellar neighbor that's been making headlines. Beetlejuice. This

165
00:10:32.600 --> 00:10:37.159
red giant star forming the distinctive shoulder of the constellation Orion,

166
00:10:37.759 --> 00:10:40.600
sits about five hundred light years away and is putting

167
00:10:40.600 --> 00:10:42.440
on quite a show as it approaches the end of

168
00:10:42.480 --> 00:10:45.960
its life. To put its size into perspective, if you

169
00:10:46.039 --> 00:10:49.720
placed Beetlejuice in our Solar system, it would extend roughly

170
00:10:49.759 --> 00:10:53.440
to the orbit of Mars. This massive star, weighing between

171
00:10:53.480 --> 00:10:56.399
fifteen to twenty times the mass of our Sun, is

172
00:10:56.440 --> 00:10:59.639
in an incredibly unstable phase of its life cycle. A

173
00:10:59.720 --> 00:11:03.080
strong estimate it could go supernova anytime within the next

174
00:11:03.080 --> 00:11:06.399
few hundred thousand years, or it might have already exploded

175
00:11:06.759 --> 00:11:10.320
with the light still traveling toward us. When Beetlejuice does

176
00:11:10.360 --> 00:11:14.360
go supernova, it will be truly spectacular. We're talking about

177
00:11:14.360 --> 00:11:17.480
an event so bright it will be visible during broad daylight,

178
00:11:17.840 --> 00:11:21.720
outshining every planet in our sky. At night, it will

179
00:11:21.720 --> 00:11:24.720
shine almost as brightly as the full moon, allowing you

180
00:11:24.759 --> 00:11:26.840
to read a book at midnight by its light alone,

181
00:11:27.240 --> 00:11:30.639
this cosmic fireworks display will last for several months before

182
00:11:30.679 --> 00:11:34.279
gradually fading away. Now you might be wondering if we

183
00:11:34.320 --> 00:11:37.440
should be concerned about having such a powerful explosion relatively

184
00:11:37.480 --> 00:11:41.480
close to Earth. The good news is that we're perfectly safe.

185
00:11:41.519 --> 00:11:45.840
While Supernova released enormous amounts of energy, the vast distance

186
00:11:45.879 --> 00:11:48.519
between us and beetlejuice means that by the time that

187
00:11:48.679 --> 00:11:51.559
energy reaches Earth, it will have spread out so much

188
00:11:51.639 --> 00:11:54.519
that it poses no threat to our planet. It's a

189
00:11:54.559 --> 00:11:58.039
perfect example of the inverse square law in action. The

190
00:11:58.120 --> 00:12:00.679
further you get from a source of radiation, the more

191
00:12:00.759 --> 00:12:04.639
dramatically its effects decrease. So when Beatle just finally does

192
00:12:04.679 --> 00:12:07.279
make its grand exit, we can simply sit back and

193
00:12:07.399 --> 00:12:10.759
enjoy the most impressive astronomical light show in human history,

194
00:12:11.120 --> 00:12:13.039
knowing we've got front row seats to one of the

195
00:12:13.159 --> 00:12:18.039
universe's most spectacular events. Well, that brings us to the

196
00:12:18.120 --> 00:12:21.480
end of another packed episode of Astronomy Daily. From those

197
00:12:21.519 --> 00:12:26.159
stranded astronauts finally heading home, to groundbreaking telescope images, multiple
