00:00:00.240 --> 00:00:03.040
Welcome to Astronomy Daily, your daily dose of space and
2
00:00:03.080 --> 00:00:06.160
astronomy news. I'm your host, Anna, and today, as we
3
00:00:06.200 --> 00:00:09.160
close out twenty twenty four, we've got an exciting lineup
4
00:00:09.240 --> 00:00:13.400
of stories from stellar explosions to perfect planetary systems and
5
00:00:13.519 --> 00:00:17.000
upcoming cometary visitors. To get us started, let's take a
6
00:00:17.000 --> 00:00:19.679
look at the latest stunning image from our most venerable
7
00:00:19.719 --> 00:00:24.679
space based telescope. The Hubble Space Telescope has captured another
8
00:00:24.800 --> 00:00:30.079
breathtaking image, this time showcasing the galaxy Lyda two two
9
00:00:30.239 --> 00:00:33.960
zero five seven, located approximately six hundred and fifty million
10
00:00:34.039 --> 00:00:37.960
light years away in the constellation Gemini. What makes this
11
00:00:38.039 --> 00:00:42.640
observation particularly special is the presence of a spectacular supernova
12
00:00:42.759 --> 00:00:47.520
explosion designated as SN twenty twenty four PI, which was
13
00:00:47.560 --> 00:00:51.759
first detected in January twenty twenty four. In the image,
14
00:00:51.880 --> 00:00:54.359
you can spot the supernova as a pale blue dot
15
00:00:54.640 --> 00:00:56.960
just below and to the right of the galaxy's core,
16
00:00:57.399 --> 00:01:01.479
creating a striking contrast against the galaxies ethereal spiral arms.
17
00:01:02.079 --> 00:01:05.959
This snapshot, taken about six weeks after its initial discovery,
18
00:01:06.239 --> 00:01:10.079
shows the supernova significantly dimmer than at its peak brightness.
19
00:01:10.959 --> 00:01:14.120
What's fascinating about Sn twenty twenty four Pi is that
20
00:01:14.159 --> 00:01:18.040
it's classified as a type IA supernova, which occurs through
21
00:01:18.120 --> 00:01:22.359
a remarkable process involving a white dwarf star. These white
22
00:01:22.400 --> 00:01:25.480
dwarfs are essentially the crystallized cores of stars that were
23
00:01:25.480 --> 00:01:29.280
originally less massive than eight times our Sun. They're incredibly
24
00:01:29.319 --> 00:01:32.239
dense objects, packing roughly the mass of our Sun into
25
00:01:32.239 --> 00:01:35.480
a sphere the size of Earth, with surface temperatures exceeding
26
00:01:35.519 --> 00:01:39.439
one hundred thousand degrees. The formation of this type of
27
00:01:39.480 --> 00:01:43.799
supernova requires a specific set of circumstances. The white dwarf
28
00:01:43.879 --> 00:01:46.239
must be part of a binary star system, where it
29
00:01:46.280 --> 00:01:49.680
can siphon material from its stellar companion. When the white
30
00:01:49.760 --> 00:01:52.920
dwarf accumulates too much mass, it reaches a critical point
31
00:01:52.959 --> 00:01:56.239
where it can no longer support itself. This triggers a
32
00:01:56.280 --> 00:02:00.680
catastrophic chain of runaway nuclear fusion, resulting in an explosion
33
00:02:00.760 --> 00:02:04.519
so bright it can be observed across vast distances of space.
34
00:02:05.640 --> 00:02:08.759
This process is particularly interesting because it represents the eventual
35
00:02:08.800 --> 00:02:12.000
fate of many stars in our galaxy, including our own Sun,
36
00:02:12.439 --> 00:02:15.800
though not all will end in such spectacular explosions. The
37
00:02:15.879 --> 00:02:19.879
discovery and observation of supernovae like SN twenty twenty four
38
00:02:19.919 --> 00:02:23.599
PI help astronomers better understand stellar revolution and the fundamental
39
00:02:23.639 --> 00:02:28.479
processes that shape our universe Next Up. Twenty twenty four
40
00:02:28.520 --> 00:02:31.080
has proven to be a record breaking year for space launches,
41
00:02:31.400 --> 00:02:34.800
with an unprecedented two hundred and fifty nine orbital missions
42
00:02:35.080 --> 00:02:38.919
successfully placing over two thousand, seven hundred payloads into orbit
43
00:02:39.000 --> 00:02:42.840
and beyond. SpaceX dominated the landscape with an astounding one
44
00:02:42.919 --> 00:02:46.479
hundred and thirty four launches, accounting for eighty five percent
45
00:02:46.560 --> 00:02:50.240
of all payloads delivered to space, including more than one thousand,
46
00:02:50.360 --> 00:02:54.800
nine hundred Starlink satellites. The United States and China emerged
47
00:02:54.840 --> 00:02:58.800
as the primary launch providers, together handling eighty percent of
48
00:02:58.879 --> 00:03:02.520
all orbital traffic. The US led with fifty four percent
49
00:03:02.560 --> 00:03:06.000
of launches, while China maintained a strong presence with twenty
50
00:03:06.039 --> 00:03:10.000
six percent. Despite launching more missions than in twenty twenty three,
51
00:03:10.560 --> 00:03:13.800
China matched its previous year's success rate of sixty five
52
00:03:13.919 --> 00:03:17.560
orbital missions, following an anomaly with their final Ligion I
53
00:03:17.759 --> 00:03:23.479
rocket launch. Rocket Lab showed impressive growth, achieving sixteen successful missions,
54
00:03:23.520 --> 00:03:27.680
a sixty percent increase from their previous year. Meanwhile, Russia's
55
00:03:27.719 --> 00:03:31.280
launch activities continued their gradual decline, ending the year with
56
00:03:31.360 --> 00:03:35.599
seventeen flights. India and Europe each conducted a handful of missions,
57
00:03:35.599 --> 00:03:39.159
but are positioning themselves for increased activity in twenty twenty five.
58
00:03:39.840 --> 00:03:43.039
The final quarter of twenty twenty four was particularly intense,
59
00:03:43.400 --> 00:03:46.759
featuring a record breaking streak of fourteen launches within just
60
00:03:46.840 --> 00:03:50.840
seven days. During November and December averaged nearly one launch
61
00:03:50.879 --> 00:03:56.960
per day with thirty orbital attempts. SpaceX achieved several significant milestones,
62
00:03:57.039 --> 00:04:00.719
including their four hundredth orbital launch in October and their
63
00:04:00.719 --> 00:04:04.520
four hundredth Falcon nine flight in November. Looking ahead to
64
00:04:04.520 --> 00:04:07.240
twenty twenty five, the space industry shows no signs of
65
00:04:07.240 --> 00:04:11.039
slowing down. Blue Origin is preparing for the highly anticipated
66
00:04:11.080 --> 00:04:14.599
debut of their new Glen heavy lift launch vehicle, while
67
00:04:14.639 --> 00:04:19.240
SpaceX continues to expand their Starlink constellation and commercial launch services.
68
00:04:20.319 --> 00:04:24.000
These developments signal an exciting new chapter in space exploration,
69
00:04:24.680 --> 00:04:29.079
with increasing launch cadence and capabilities across the industry. The
70
00:04:29.160 --> 00:04:32.920
year's achievements demonstrate not just the growing commercialization of space,
71
00:04:33.279 --> 00:04:37.800
but also the incredible reliability and efficiency of modern launch systems,
72
00:04:37.839 --> 00:04:41.040
setting new standards for what's possible in space access and
73
00:04:41.160 --> 00:04:46.560
orbital operations. While on the subject of successful launches, India's
74
00:04:46.560 --> 00:04:50.879
space program has marked another significant milestone with the successful
75
00:04:50.920 --> 00:04:55.519
launch of their space docking experiment, known as SPADEX. The
76
00:04:55.560 --> 00:04:59.439
mission lifted off on December thirtieth from the Satish Dowan
77
00:04:59.600 --> 00:05:03.839
Space Center aboard of Polar Satellite launch vehicle, carrying two
78
00:05:03.920 --> 00:05:09.040
specialized spacecraft designed to test crucial docking technologies. The mission
79
00:05:09.079 --> 00:05:12.839
features two two hundred twenty kilogram spacecraft, a chaser and
80
00:05:12.879 --> 00:05:16.560
a target, placed into precise four hundred seventy five kilometers
81
00:05:16.680 --> 00:05:21.040
circular orbits. These spacecraft are equipped with advanced technology, including
82
00:05:21.040 --> 00:05:25.319
a low impact docking system, laser range finders, and sophisticated
83
00:05:25.360 --> 00:05:29.560
sensors to enable precise orbital maneuvers. What makes this mission
84
00:05:29.560 --> 00:05:33.480
particularly noteworthy is its role in India's broader space ambitions.
85
00:05:34.040 --> 00:05:37.720
The technology being tested is essential for India's Gagannion program,
86
00:05:37.920 --> 00:05:40.720
which aims to make India only the fourth nation capable
87
00:05:40.759 --> 00:05:44.199
of independent human spaceflight. The first crude mission under this
88
00:05:44.240 --> 00:05:47.920
program is scheduled for twenty twenty six, following uncrued test
89
00:05:47.920 --> 00:05:51.720
flights planned for twenty twenty five, but the implications extend
90
00:05:51.720 --> 00:05:55.279
beyond human spaceflight. These docking capabilities will be crucial for
91
00:05:55.360 --> 00:05:59.399
India's ambitious Chandrion four lunar mission, targeted for twenty twenty
92
00:05:59.439 --> 00:06:02.800
seven or TIX twenty eight. This mission plans to collect
93
00:06:02.839 --> 00:06:06.319
samples from the Moon's south pole and return them to Earth,
94
00:06:06.720 --> 00:06:10.279
a feat that requires precise orbital docking maneuvers to transfer
95
00:06:10.319 --> 00:06:13.759
the precious lunar samples from the ascent vehicle to the
96
00:06:13.800 --> 00:06:19.439
return spacecraft. The mission's secondary payload module, POEM four, carried
97
00:06:19.519 --> 00:06:23.480
twenty four different experiments, including innovative technologies like a walking
98
00:06:23.560 --> 00:06:28.680
robotic arm, a debriscapture system, and various research modules. This
99
00:06:28.720 --> 00:06:32.600
demonstrates India's commitment to maximizing the scientific value of each
100
00:06:32.680 --> 00:06:37.600
launch while advancing their technological capabilities. The successful deployment of
101
00:06:37.680 --> 00:06:41.160
both spacecraft marks just the beginning of this experimental mission.
102
00:06:41.639 --> 00:06:45.279
The actual docking maneuver, scheduled for early January, will be
103
00:06:45.319 --> 00:06:49.120
the true test of these new capabilities. If successful, it
104
00:06:49.160 --> 00:06:52.360
will represent a major step forward in India's journey toward
105
00:06:52.439 --> 00:06:57.000
becoming a complete spacefaring nation. Twenty twenty four proved to
106
00:06:57.000 --> 00:07:00.519
be a particularly challenging year for NASA, with several dramatic
107
00:07:00.560 --> 00:07:05.759
developments testing the agency's resilience and problem solving capabilities. Perhaps
108
00:07:05.759 --> 00:07:09.439
most notably, what began as a routine mission turned into
109
00:07:09.439 --> 00:07:13.480
an extended stay aboard the International Space Station for astronauts
110
00:07:13.639 --> 00:07:19.040
Sunny Williams and Butch Wilmore. Their Boeing Starliner spacecraft encountered
111
00:07:19.040 --> 00:07:22.720
issues with helium leaks and thruster problems during its approach
112
00:07:22.759 --> 00:07:26.319
to the ISS, leading NASA to make the cautious decision
113
00:07:26.360 --> 00:07:29.879
to return the spacecraft empty, leaving the crew stranded until
114
00:07:29.879 --> 00:07:33.759
at least February twenty twenty five. In an ironic twist,
115
00:07:34.079 --> 00:07:36.920
these Boeing test pilots will ultimately return home aboard a
116
00:07:36.959 --> 00:07:40.800
space X Dragon spacecraft, extending their intended three month mission
117
00:07:40.879 --> 00:07:44.319
to eight and a half months. This situation highlighted the
118
00:07:44.319 --> 00:07:49.360
ongoing challenges in developing reliable commercial crew transportation systems. On Mars,
119
00:07:49.519 --> 00:07:53.040
we witness the bittersweet end of an extraordinary mission, as
120
00:07:53.079 --> 00:07:56.639
the Ingenuity helicopter made its final flight on January eighteenth.
121
00:07:57.120 --> 00:07:59.759
While its crash landing marked the conclusion of its journey,
122
00:08:00.519 --> 00:08:04.959
Ingenuity had far exceeded all expectations, completing seventy one flights
123
00:08:05.000 --> 00:08:07.759
over nearly three years when it was originally designed for
124
00:08:07.920 --> 00:08:11.959
just a handful of demonstrations over thirty days, this small
125
00:08:12.079 --> 00:08:15.399
one point eight kilogram helicopter proved that powered flight was
126
00:08:15.439 --> 00:08:19.720
possible in Mars's extremely thin atmosphere equivalent to Earth's atmosphere
127
00:08:19.800 --> 00:08:23.639
at eighty thousand feet. The Europa Clipper mission faced its
128
00:08:23.639 --> 00:08:28.480
own dramatic challenges. Just months before launch, engineers discovered hundreds
129
00:08:28.519 --> 00:08:32.759
of potentially compromised transistors that might not withstand Jupiter's intense
130
00:08:32.879 --> 00:08:36.440
radiation belts. After four months of round the clock testing,
131
00:08:36.960 --> 00:08:40.039
they found a workable solution by maintaining the transistors at
132
00:08:40.120 --> 00:08:44.039
room temperature, though this required additional power from the spacecraft's
133
00:08:44.080 --> 00:08:48.159
massive solar panels. In a final dramatic turn, one of
134
00:08:48.200 --> 00:08:52.480
the most intense Gulf of Mexico hurricanes ever recorded threatened
135
00:08:52.559 --> 00:08:57.000
the mission's launch. Fortunately, the storm weakened as it crossed Florida,
136
00:08:57.360 --> 00:09:01.120
allowing the spacecraft to launch successfully during a backup window.
137
00:09:02.279 --> 00:09:05.080
The Europa Clipper is now en route to its twenty
138
00:09:05.120 --> 00:09:08.279
twenty five Mars flyby, which will help propel it toward
139
00:09:08.279 --> 00:09:11.960
its ultimate destination at Jupiter. All in all, quite a
140
00:09:12.039 --> 00:09:17.039
challenging year for NASA now on to an exciting discovery.
141
00:09:17.840 --> 00:09:20.639
Located just one hundred and five light years away in
142
00:09:20.679 --> 00:09:25.399
the constellation Coma Baronesis, astronomers have discovered a remarkable star
143
00:09:25.480 --> 00:09:30.559
system that's been dubbed mathematically perfect. The star HD one
144
00:09:30.600 --> 00:09:33.919
to one zero zero six seven hosts six exoplanets that
145
00:09:34.039 --> 00:09:38.120
orbit in an incredibly synchronized dance, locked together by gravitational
146
00:09:38.159 --> 00:09:43.000
forces in a precise cosmic choreography. While this celestial ballet
147
00:09:43.039 --> 00:09:46.960
initially suggested a mature, well established system, new research has
148
00:09:47.039 --> 00:09:51.120
dramatically revised our understanding of its age. Previous estimates using
149
00:09:51.120 --> 00:09:54.600
traditional stellar aging methods, placed the system at around eight
150
00:09:54.679 --> 00:09:58.080
billion years old. However, a fresh analysis of the star's
151
00:09:58.080 --> 00:10:01.519
activity levels and rotation rates suggest us it's actually much younger,
152
00:10:01.919 --> 00:10:05.279
only about two point five billion years old. The team
153
00:10:05.360 --> 00:10:08.799
reached this conclusion by examining telltale signs of stellar youth,
154
00:10:09.360 --> 00:10:12.840
including higher levels of ionized calcium in the star's atmosphere
155
00:10:13.120 --> 00:10:15.679
and a faster rotation rate compared to older stars like
156
00:10:15.720 --> 00:10:19.159
our sun. HD one one zero zero six seven completes
157
00:10:19.200 --> 00:10:22.279
one rotation in about twenty earth days, while our more
158
00:10:22.320 --> 00:10:25.440
elderly son takes at least twenty seven days, indicating this
159
00:10:25.519 --> 00:10:29.000
star is still in its relative youth. This discovery of
160
00:10:29.000 --> 00:10:32.799
the system's younger age has important implications for potential habitability.
161
00:10:33.399 --> 00:10:36.000
While the six known planets orbit too close to their
162
00:10:36.039 --> 00:10:39.080
parent star to support life as we know it, there
163
00:10:39.080 --> 00:10:43.279
could be additional undiscovered planets in more temperate zones. However,
164
00:10:43.480 --> 00:10:46.559
the star's younger age means it's likely still producing intense
165
00:10:46.679 --> 00:10:50.279
radiation that could make life challenging on any world's orbiting
166
00:10:50.279 --> 00:10:54.679
within its habitable zone. What makes this system particularly fascinating
167
00:10:54.759 --> 00:10:58.200
is how quickly its planets achieved their perfect orbital resonance,
168
00:10:59.000 --> 00:11:03.159
rather than require billions of years of gradual settling. Researchers
169
00:11:03.200 --> 00:11:06.919
now believe this synchronized orbital pattern may have established itself
170
00:11:07.240 --> 00:11:10.759
in as little as one billion years through gravitational interactions
171
00:11:10.759 --> 00:11:14.519
between the planets. As we look ahead to early twenty
172
00:11:14.559 --> 00:11:19.440
twenty five, skywatchers have an exciting visitor to anticipate. Comet Atlas,
173
00:11:19.639 --> 00:11:23.480
officially designated C twenty twenty four G three, is making
174
00:11:23.519 --> 00:11:26.000
its way toward the Inner Solar System and could provide
175
00:11:26.039 --> 00:11:29.559
quite a spectacle, particularly for observers in the southern hemisphere.
176
00:11:30.360 --> 00:11:33.080
The comet is scheduled to reach its closest approach to
177
00:11:33.120 --> 00:11:37.799
the Sun on January thirteenth, twenty twenty five, coming within
178
00:11:37.840 --> 00:11:40.399
a mere eight point three million miles of our star.
179
00:11:41.200 --> 00:11:44.440
To put that in perspective, that significantly closer than Mercury's
180
00:11:44.480 --> 00:11:47.919
closest approach to the Sun. This close encounter means the
181
00:11:47.919 --> 00:11:50.600
comet could potentially shine as brightly as Venus in our
182
00:11:50.679 --> 00:11:54.799
night sky. However, this extremely close solar approach comes with
183
00:11:54.919 --> 00:11:58.600
risks for the comet itself. While analysis of its orbital
184
00:11:58.639 --> 00:12:01.720
paths suggests it previously visited the inner Solar System about
185
00:12:01.759 --> 00:12:05.000
one hundred and sixty thousand years ago, there's no guarantee
186
00:12:05.000 --> 00:12:08.039
it will survive this encounter. The intense heat from such
187
00:12:08.080 --> 00:12:10.679
a close solar pass could potentially cause the comet to
188
00:12:10.679 --> 00:12:15.039
break apart. If Atlas does survive its solar encounter, observers
189
00:12:15.080 --> 00:12:17.759
in the southern Hemisphere will be ideally positioned to view
190
00:12:17.799 --> 00:12:21.480
it in the western sky after sunset. The timing isn't perfect, though,
191
00:12:21.799 --> 00:12:24.879
as the full moon on January thirteenth will create some interference,
192
00:12:25.399 --> 00:12:29.000
but viewing conditions should improve each subsequent evening as the
193
00:12:29.039 --> 00:12:32.679
moon rises later. The comet was first spotted on April fifth,
194
00:12:32.960 --> 00:12:36.679
twenty twenty four by the Asteroid Terrestrial Impact Last Alert
195
00:12:36.759 --> 00:12:41.080
System or ATLAS, which gives the comet its name. Like
196
00:12:41.159 --> 00:12:43.960
many of its kind, it originates from the ort cloud,
197
00:12:44.480 --> 00:12:48.720
that vast sphere of icy bodies surrounding our Solar System.
198
00:12:49.039 --> 00:12:51.759
Whether it survives its close encounter with the Sun or not,
199
00:12:52.399 --> 00:12:55.279
Comet Atlas promises to provide an interesting start to the
200
00:12:55.320 --> 00:13:00.279
astronomical calendar of twenty twenty five, and that brings us
