00:00:00.200 --> 00:00:02.640
Welcome to Astronomy Daily, your source for the latest space

2
00:00:02.640 --> 00:00:05.960
and astronomy news. I'm your host, Anna, and today we'll

3
00:00:06.000 --> 00:00:08.519
be covering a range of exciting topics, from space debris

4
00:00:08.519 --> 00:00:11.080
to black holes, a spy story, and even space tourism.

5
00:00:11.480 --> 00:00:14.320
Get ready for a cosmic journey through the latest discoveries

6
00:00:14.359 --> 00:00:18.600
and developments in the world of space exploration. Let's kick

7
00:00:18.640 --> 00:00:20.640
things off with one of the biggest problems facing the

8
00:00:20.679 --> 00:00:24.039
space industry today, and fortunately steps are being taken to

9
00:00:24.079 --> 00:00:27.760
address the problem. The European Space Agency is taking significant

10
00:00:27.800 --> 00:00:30.879
steps to address the growing issue of space debris with

11
00:00:30.920 --> 00:00:34.840
their innovative Zero Debris Charter. This initiative, launched in November

12
00:00:34.880 --> 00:00:38.759
twenty twenty three, aims to boost international cooperation in solving

13
00:00:38.799 --> 00:00:42.679
Earth's escalating space junk problem. The charter has gained impressive traction,

14
00:00:43.200 --> 00:00:46.359
with over one hundred signatories joining the cause. At a

15
00:00:46.359 --> 00:00:51.079
recent ceremony during the International Astronautical Congress in Milan, twenty

16
00:00:51.159 --> 00:00:54.560
four new partners signed on, including New Zealand and Mexico,

17
00:00:55.000 --> 00:00:58.159
the first countries outside Europe to do so. What makes

18
00:00:58.159 --> 00:01:01.159
this charter unique is its voluntary names. It's not a

19
00:01:01.200 --> 00:01:04.480
regulatory document, but rather a collaborative effort within the global

20
00:01:04.519 --> 00:01:08.840
space community. The charter outlines goals and guiding principles which

21
00:01:08.879 --> 00:01:13.079
will be developed into actionable and measurable targets. These principles

22
00:01:13.079 --> 00:01:18.760
include preventing intentional debris creation, anticipating and mitigating adverse effects,

23
00:01:19.239 --> 00:01:22.920
and promoting constant efforts to understand the problem. The charter

24
00:01:23.040 --> 00:01:26.519
also advocates for timely removal of spacecraft from orbit at

25
00:01:26.519 --> 00:01:29.280
the end of their missions and safe re entry practices.

26
00:01:30.480 --> 00:01:33.519
With an estimated million plus pieces of debris larger than

27
00:01:33.560 --> 00:01:37.239
a centimeter orbiting Earth, this initiative couldn't be more timely.

28
00:01:37.640 --> 00:01:40.599
It's a crucial step towards ensuring that space remains clean

29
00:01:40.680 --> 00:01:44.280
and safe for future generations and ongoing space operations.

30
00:01:45.760 --> 00:01:46.200
Next up.

31
00:01:46.200 --> 00:01:48.200
This sounds like a plot from a James Bond movie,

32
00:01:48.200 --> 00:01:51.159
but it's a real concern. In a recent development, China

33
00:01:51.200 --> 00:01:54.480
has raised concerns about foreign espionage targeting their space program.

34
00:01:54.840 --> 00:01:57.640
The Chinese government claims that foreign spies are attempting to

35
00:01:57.640 --> 00:02:01.920
steal secrets related to their space initiatives. This revelation highlights

36
00:02:01.959 --> 00:02:05.280
the growing tensions in the realm of space exploration and technology.

37
00:02:05.640 --> 00:02:09.120
While details are limited, this accusation underscores the competitive nature

38
00:02:09.159 --> 00:02:12.919
of space programs worldwide. It also raises questions about international

39
00:02:12.919 --> 00:02:16.919
cooperation and transparency in space related activities. As countries like

40
00:02:17.000 --> 00:02:20.520
China continue to advance their space capabilities, the potential for

41
00:02:20.639 --> 00:02:25.080
increased suspicion and security measures could impact global space relations.

42
00:02:25.560 --> 00:02:28.599
This situation serves as a reminder of the delicate balance

43
00:02:28.639 --> 00:02:32.639
between national interests and the collaborative spirit that has traditionally

44
00:02:32.719 --> 00:02:36.479
characterized space exploration. As we move forward, it will be

45
00:02:36.520 --> 00:02:40.280
crucial to monitor how these concerns shape future international space

46
00:02:40.319 --> 00:02:45.520
partnerships and information sharing. Next up, something making headlines in

47
00:02:45.560 --> 00:02:49.879
the astronomy world. In a groundbreaking discovery, astronomers have identified

48
00:02:49.919 --> 00:02:53.120
a unique triple system featuring a black hole with two

49
00:02:53.360 --> 00:02:57.560
orbiting stars. This remarkable find, described in a recent paper

50
00:02:57.560 --> 00:03:01.120
published in Nature, centers around V four hundred four signy,

51
00:03:01.560 --> 00:03:04.719
a black hole located about eight thousand light years from Earth.

52
00:03:05.199 --> 00:03:08.919
What makes this system particularly intriguing is its configuration. The

53
00:03:08.960 --> 00:03:12.199
first star, orbits V four hundred four signa every six

54
00:03:12.240 --> 00:03:15.840
point five days, so close that it's actually shedding material

55
00:03:15.879 --> 00:03:19.199
into the black hole's gravitational grasp. But it's the second

56
00:03:19.240 --> 00:03:23.000
star that's caught scientist's attention. This outer star is incredibly

57
00:03:23.039 --> 00:03:26.879
distant from the black hole, orbiting once every seventy thousand

58
00:03:26.919 --> 00:03:29.840
years at a distance one hundred times that between Pluto

59
00:03:30.319 --> 00:03:34.080
and our Sun. This discovery challenges our understanding of black

60
00:03:34.120 --> 00:03:37.599
hole formation. Typically, we believe black holes form from violent

61
00:03:37.680 --> 00:03:41.919
stellar explosions, which should disperse nearby objects. However, the presence

62
00:03:41.960 --> 00:03:46.479
of this distant star suggests a gentler formation process. Computer

63
00:03:46.560 --> 00:03:50.719
simulations indicate that the most likely scenario is a direct collapse,

64
00:03:51.159 --> 00:03:53.759
where the star that became the black hole simply caved

65
00:03:53.800 --> 00:03:57.400
in on itself without a dramatic explosion. This method would

66
00:03:57.400 --> 00:04:00.560
have allowed the distant star to remain gravitational bound to

67
00:04:00.599 --> 00:04:04.280
the system. This triple system not only provides new insights

68
00:04:04.280 --> 00:04:07.800
into black hole formation, but also helps astronomers determine the

69
00:04:07.840 --> 00:04:11.080
age of V four hundred four signy, estimated to be

70
00:04:11.120 --> 00:04:14.039
about four billion years old. As we continue to study

71
00:04:14.080 --> 00:04:17.879
this fascinating cosmic dance, we're sure to uncover more secrets

72
00:04:17.920 --> 00:04:20.480
about the nature of black holes and the evolution of

73
00:04:20.480 --> 00:04:25.639
our universe. Now, another story featuring the ESA. The European

74
00:04:25.680 --> 00:04:28.839
Space Agency's EUCLID mission has just released an incredible two

75
00:04:28.879 --> 00:04:31.879
hundred eight gigapixel mosaic of the Southern Sky, and it's

76
00:04:31.879 --> 00:04:35.000
a site to behold. This massive image covers an area

77
00:04:35.040 --> 00:04:37.319
more than five hundred times larger than a full moon,

78
00:04:37.759 --> 00:04:41.079
giving us a tantalizing glimpse into the vastness of our universe.

79
00:04:41.439 --> 00:04:44.800
But EUCLID isn't just about pretty pictures. This space telescope

80
00:04:44.800 --> 00:04:47.759
has a crucial mission to help us understand the mysterious

81
00:04:47.759 --> 00:04:51.240
force known as dark energy. Scientists believe dark energy is

82
00:04:51.279 --> 00:04:54.959
responsible for the accelerating expansion of our universe, but we

83
00:04:55.000 --> 00:04:58.480
still know very little about it. To tackle this cosmic mystery,

84
00:04:58.680 --> 00:05:01.600
EUCLID will map billions of galaxies across ten billion light

85
00:05:01.680 --> 00:05:04.800
years of space. This preliminary data release is just a

86
00:05:04.800 --> 00:05:07.759
small taste of what's to come. Over the next six years,

87
00:05:07.759 --> 00:05:11.240
EUCLID will survey an area thousands of times larger, creating

88
00:05:11.279 --> 00:05:14.639
the most extensive three D map of the cosmos ever constructed.

89
00:05:15.720 --> 00:05:19.920
What's truly remarkable is that this initial mosaic, representing just

90
00:05:20.000 --> 00:05:24.199
one percent of euclid's total survey area, already contains around

91
00:05:24.199 --> 00:05:25.879
one hundred million.

92
00:05:25.560 --> 00:05:26.920
Stars and galaxies.

93
00:05:27.360 --> 00:05:30.040
Of these, about fourteen million galaxies could be used to

94
00:05:30.040 --> 00:05:33.720
study dark energy's influence on the universe. As EUCLID continues

95
00:05:33.759 --> 00:05:38.000
its mission, it will provide unprecedented insights into the structure

96
00:05:38.040 --> 00:05:42.160
and evolution of our universe, potentially revolutionizing our understanding of

97
00:05:42.199 --> 00:05:47.560
cosmology and the fundamental forces that shape our reality. In

98
00:05:47.600 --> 00:05:50.399
a recent development, NASA has put the brakes on plans

99
00:05:50.439 --> 00:05:53.560
to reduce operations of two major space telescopes as a

100
00:05:53.560 --> 00:05:54.439
cost cutting measure.

101
00:05:54.839 --> 00:05:56.560
The decision regarding budget.

102
00:05:56.199 --> 00:05:58.680
Cuts for the Chandra X Ray Observatory and Hubble Space

103
00:05:58.720 --> 00:06:02.199
Telescope has been deferred until after the agency receives its

104
00:06:02.240 --> 00:06:06.439
final appropriations for fiscal year twenty twenty five. This delay

105
00:06:06.519 --> 00:06:09.120
comes as a relief to many in the scientific community

106
00:06:09.439 --> 00:06:12.839
who were concerned about the potential impact on these vital instruments.

107
00:06:13.240 --> 00:06:16.399
The proposed cuts were significant, with Chandra facing a forty

108
00:06:16.439 --> 00:06:19.480
percent reduction in its operating budget and Hubble looking at

109
00:06:19.519 --> 00:06:22.160
a ten percent cut. The delay allows for more time

110
00:06:22.199 --> 00:06:26.319
to assess the situation and potentially find alternative solutions. It

111
00:06:26.360 --> 00:06:29.720
also highlights the ongoing challenges of balancing a diverse portfolio

112
00:06:29.839 --> 00:06:33.920
of missions within budget constraints. As we await the final

113
00:06:33.959 --> 00:06:38.279
budget decisions, the scientific community remains hopeful that these iconic

114
00:06:38.319 --> 00:06:42.879
telescopes will continue their groundbreaking work in unraveling the mysteries

115
00:06:42.920 --> 00:06:47.319
of our universe. Next, let's turn our attention to another

116
00:06:47.399 --> 00:06:51.319
big scientific discovery from way out there. In a groundbreaking discovery,

117
00:06:51.600 --> 00:06:54.639
astronomers have found one of the largest carbon based molecules

118
00:06:54.639 --> 00:06:59.040
ever detected in deep space. The molecule, called Pirini, was

119
00:06:59.079 --> 00:07:02.439
located within the Chorous Molecular Cloud about four hundred and

120
00:07:02.480 --> 00:07:05.680
thirty light years from Earth. This finding is significant because

121
00:07:05.720 --> 00:07:09.199
it provides crucial clues that could help solve a long

122
00:07:09.240 --> 00:07:14.120
standing mystery in astrochemistry, the origin of carbon, the building

123
00:07:14.160 --> 00:07:18.480
block of life. Pyrene is a polycyclic aromatic hydrocarbon or PAH,

124
00:07:18.959 --> 00:07:21.800
made up of four fused planar rings of carbon. These

125
00:07:21.800 --> 00:07:24.720
molecules are among the most abundant complex molecules in the

126
00:07:24.759 --> 00:07:27.720
visible universe, and are thought to make up roughly twenty

127
00:07:27.720 --> 00:07:31.279
percent of the carbon found in space. What's particularly intriguing

128
00:07:31.279 --> 00:07:33.600
about this discovery is that purine was found in an

129
00:07:33.600 --> 00:07:36.639
extremely cold environment, with temperatures as low as ten kelvin.

130
00:07:37.079 --> 00:07:40.560
This challenges our understanding of how these molecules form, as

131
00:07:40.560 --> 00:07:45.399
on Earth, they're typically created through high temperature processes. The

132
00:07:45.439 --> 00:07:48.040
presence of pyrene in the birthplace of our Solar system

133
00:07:48.079 --> 00:07:51.439
provides a direct link between the early molecular clouds and

134
00:07:51.480 --> 00:07:55.879
the composition of celestial bodies like asteroids. This connection offers

135
00:07:56.000 --> 00:07:59.560
valuable insights into the chemical evolution of our cosmic neighborhood

136
00:07:59.600 --> 00:08:04.319
and potent meally the origins of life itself. Finally, today

137
00:08:04.360 --> 00:08:06.800
it looks like we have another space tourism provider on

138
00:08:06.839 --> 00:08:10.839
the horizon. In an exciting development for space enthusiasts, a

139
00:08:10.920 --> 00:08:15.680
Chinese company called Jiangsu Deep Blue Aerospace Technology has announced

140
00:08:15.720 --> 00:08:19.439
its now taking pre orders for suborbital space tourism flights,

141
00:08:19.800 --> 00:08:22.879
with the first launch planned for twenty twenty seven. The

142
00:08:22.920 --> 00:08:26.480
company's CEO, Hua Yang shared details of their commercial spacecraft

143
00:08:26.560 --> 00:08:30.199
during a recent live broadcast. Deep Blue Aerospace's plans include

144
00:08:30.199 --> 00:08:33.840
a reusable rocket called Nebula one, which bears some resemblance

145
00:08:33.840 --> 00:08:37.440
to SpaceX's Falcon nine. Their spacecraft is designed to carry

146
00:08:37.480 --> 00:08:40.960
six passengers to an altitude of one hundred kilometers, crossing

147
00:08:41.000 --> 00:08:44.519
the Carmen Line, the official boundary of space. Passengers will

148
00:08:44.559 --> 00:08:47.919
experience about five minutes of weightlessness during the twelve minute flight.

149
00:08:48.480 --> 00:08:51.679
This move puts China in direct competition with established players

150
00:08:51.679 --> 00:08:55.120
in the space tourism market like Virgin Galactic, Blue Origin,

151
00:08:55.159 --> 00:09:00.279
and SpaceX. While these companies have already conducted successful flights,

152
00:09:00.360 --> 00:09:03.480
entry into the field could potentially make space tourism.

153
00:09:03.120 --> 00:09:04.360
More accessible globally.

154
00:09:06.360 --> 00:09:09.879
