00:00:00.320 --> 00:00:02.790
Anna: Hey there, space enthusiasts and welcome back

1
00:00:02.790 --> 00:00:05.790
to Astronomy Daily. I'm your host, Anna, and

2
00:00:05.790 --> 00:00:08.070
I'm super excited to take you on a whirlwind

3
00:00:08.070 --> 00:00:09.990
tour of the cosmos right from the comfort of

4
00:00:09.990 --> 00:00:12.270
your earbuds. Today we've got some mind

5
00:00:12.270 --> 00:00:14.470
blowing stories lined up. We'll be diving

6
00:00:14.470 --> 00:00:16.270
into the mystery of Titan's wobbling

7
00:00:16.270 --> 00:00:18.510
atmosphere, checking out a newly discovered

8
00:00:18.510 --> 00:00:21.030
ancient monster galaxy, and looking into the

9
00:00:21.030 --> 00:00:23.310
delays plaguing Boeing's Starliner programme.

10
00:00:23.870 --> 00:00:25.910
And we'll wrap it all up with a peek into the

11
00:00:25.910 --> 00:00:27.710
next 50 years in space, according to the

12
00:00:27.710 --> 00:00:30.310
Royal Society. So buckle up space cadets.

13
00:00:30.310 --> 00:00:31.470
It's going to be a fun R.

14
00:00:33.050 --> 00:00:34.890
Alright, first up, let's talk about Titan,

15
00:00:34.970 --> 00:00:37.210
Saturn's largest moon. Now get this.

16
00:00:37.370 --> 00:00:39.170
Scientists have discovered that Titan's

17
00:00:39.170 --> 00:00:41.610
atmosphere isn't exactly sitting still. It

18
00:00:41.610 --> 00:00:44.010
like wobbles. Yeah, you heard me right.

19
00:00:44.170 --> 00:00:46.970
Wobbles like a gyroscope. A recent

20
00:00:46.970 --> 00:00:49.650
study after analysing infrared light readings

21
00:00:49.650 --> 00:00:52.050
over 13 years has revealed that Titan's

22
00:00:52.050 --> 00:00:53.730
atmosphere isn't fixed in line with its

23
00:00:53.730 --> 00:00:56.250
surface. It shifts across the seasons.

24
00:00:56.570 --> 00:00:59.190
Spooky. Huh? Huh? Now the big question is

25
00:00:59.430 --> 00:01:01.910
why? What's causing this weird wobble?

26
00:01:02.790 --> 00:01:04.910
Planetary scientist Lucy Wright compares it

27
00:01:04.910 --> 00:01:07.190
to a gyroscope stabilising itself in space

28
00:01:07.350 --> 00:01:10.030
and adds that the wobble changes with Titan's

29
00:01:10.030 --> 00:01:12.870
seasons. One theory is that it has something

30
00:01:12.870 --> 00:01:14.870
to do with Titan's orbit around the sun and

31
00:01:14.870 --> 00:01:17.230
Saturn. But the direction of the tilt remains

32
00:01:17.230 --> 00:01:20.070
fixed, which is just adding to the mystery.

33
00:01:20.630 --> 00:01:23.470
Maybe, and this is just a maybe. A large

34
00:01:23.470 --> 00:01:25.510
impact event in Titan's past could have

35
00:01:25.510 --> 00:01:28.080
started the wobbles and possibly changed its

36
00:01:28.080 --> 00:01:31.040
climate. Now why should we care? Well, this

37
00:01:31.040 --> 00:01:32.640
research is crucial for the upcoming

38
00:01:32.640 --> 00:01:35.280
Dragonfly mission scheduled for 2034.

39
00:01:35.440 --> 00:01:37.960
Dragonfly's gonna land on Titan and to do

40
00:01:37.960 --> 00:01:40.240
that safely, we need to really understand its

41
00:01:40.240 --> 00:01:43.120
atmosphere. Plus understanding

42
00:01:43.120 --> 00:01:45.560
Titan's atmosphere, which by the way, is the

43
00:01:45.560 --> 00:01:47.440
only moon in our solar system to have a

44
00:01:47.440 --> 00:01:49.600
proper atmosphere, might help us understand

45
00:01:49.600 --> 00:01:52.490
how life could survive on other planets. Even

46
00:01:52.490 --> 00:01:54.770
better, studying Titan could even help us

47
00:01:54.770 --> 00:01:57.050
understand Earth's atmosphere better. Who

48
00:01:57.050 --> 00:01:57.330
knew?

49
00:01:57.330 --> 00:02:00.050
Right, next up, we're heading

50
00:02:00.050 --> 00:02:02.890
way, way back in time, like 11.1

51
00:02:02.890 --> 00:02:05.330
billion years back. Astronomers have just

52
00:02:05.330 --> 00:02:08.170
spotted a massive super active spiral galaxy

53
00:02:08.330 --> 00:02:10.130
from the early universe. And it's shedding

54
00:02:10.130 --> 00:02:12.170
new light on how galaxies like our own Milky

55
00:02:12.170 --> 00:02:14.610
Way took shape. Now this galaxy ain't just

56
00:02:14.610 --> 00:02:16.110
any galaxy. It's what they call a, ah,

57
00:02:16.170 --> 00:02:18.810
monster galaxy that's growing super fast by

58
00:02:18.810 --> 00:02:21.570
making stars at an incredible rate. It's got

59
00:02:21.570 --> 00:02:23.810
a bright central bar, a feature seen in many

60
00:02:23.810 --> 00:02:26.130
modern spiral galaxies, including our own,

61
00:02:26.450 --> 00:02:28.890
this bar acts like a funnel directing gas

62
00:02:28.890 --> 00:02:31.250
inward to fuel the birth of new stars.

63
00:02:31.650 --> 00:02:34.650
And this one, called J0107A. It's like

64
00:02:34.650 --> 00:02:36.969
the oldest and most massive barred spiral

65
00:02:36.969 --> 00:02:39.770
galaxy we've ever seen. Think of it as a time

66
00:02:39.770 --> 00:02:42.450
capsule, giving us a peek into how these

67
00:02:42.450 --> 00:02:44.970
galactic structures formed and evolved way

68
00:02:44.970 --> 00:02:47.500
back in the early universe. What's really

69
00:02:47.500 --> 00:02:50.140
cool is that the team found that the gas in

70
00:02:50.140 --> 00:02:53.100
J0107A is distributed

71
00:02:53.100 --> 00:02:55.260
and moves in a way that's similar to modern

72
00:02:55.260 --> 00:02:57.660
galaxies. But get this, the

73
00:02:57.660 --> 00:03:00.180
concentrations of gas are way higher and the

74
00:03:00.180 --> 00:03:02.140
speed of the gas flow is much faster.

75
00:03:03.100 --> 00:03:05.580
Astronomers think this massive influx of gas

76
00:03:05.580 --> 00:03:08.100
to the centre of the galaxy will cause even

77
00:03:08.100 --> 00:03:10.700
more star formation, driving its evolution.

78
00:03:11.100 --> 00:03:12.900
This is the first time these features have

79
00:03:12.900 --> 00:03:14.700
been observed. And turns out they weren't

80
00:03:14.700 --> 00:03:16.940
predicted by any of the theoretical models.

81
00:03:17.690 --> 00:03:19.870
How about that, huh? Huh?

82
00:03:19.870 --> 00:03:21.410
Alright, let's turn our attention back to

83
00:03:21.410 --> 00:03:23.170
Earth, or at least to Earth's space

84
00:03:23.170 --> 00:03:25.770
programmes. Remember Boeing's Starliner?

85
00:03:25.930 --> 00:03:28.010
Well, a year ago it was docking with the

86
00:03:28.010 --> 00:03:29.730
International Space Station for its crew

87
00:03:29.730 --> 00:03:31.850
flight test with NASA astronauts Sunita

88
00:03:31.850 --> 00:03:34.120
Williams and Barry Wilmore. But, a year

89
00:03:34.120 --> 00:03:36.360
later, the future of the Starliner programme

90
00:03:36.440 --> 00:03:38.600
is, well, still up in the air.

91
00:03:39.480 --> 00:03:41.800
NASA just announced that the next flight has

92
00:03:41.800 --> 00:03:43.920
been delayed again. This time from late

93
00:03:43.920 --> 00:03:46.520
2025 to early 2026

94
00:03:47.200 --> 00:03:49.840
at the soonest. And get this, they're still

95
00:03:49.840 --> 00:03:51.680
deciding whether or not the next flight will

96
00:03:51.680 --> 00:03:54.640
even have astronauts on board. Seriously,

97
00:03:54.960 --> 00:03:57.360
Sunita Williams even told readers that flying

98
00:03:57.360 --> 00:04:00.000
an uncrewed Starliner flight next would be

99
00:04:00.240 --> 00:04:02.839
the logical thing to do. Makes you wonder

100
00:04:02.839 --> 00:04:05.600
what's going on, doesn't it? So after its

101
00:04:05.600 --> 00:04:07.120
first mission with a crew last June,

102
00:04:07.360 --> 00:04:09.840
lingering issues with helium leaks and

103
00:04:09.920 --> 00:04:12.120
propulsion system anomalies caused the

104
00:04:12.120 --> 00:04:14.680
spacecraft to, you know, return to Earth

105
00:04:14.680 --> 00:04:17.440
without its crew. Ouch. Now

106
00:04:17.440 --> 00:04:19.240
NASA and Boeing are trying to figure out how

107
00:04:19.240 --> 00:04:21.760
to fix these issues. They're doing tests at

108
00:04:21.760 --> 00:04:24.280
the White Sands Test Facility, firing up key

109
00:04:24.280 --> 00:04:26.280
thrusters to validate their thermal models

110
00:04:26.280 --> 00:04:29.040
and look at potential upgrades. And about

111
00:04:29.040 --> 00:04:31.040
those astronauts, who's going to be on the

112
00:04:31.040 --> 00:04:33.200
first crewed mission whenever that happens?

113
00:04:33.840 --> 00:04:36.320
Well, even NASA and the Canadian Space

114
00:04:36.320 --> 00:04:38.640
Agency are being kind of cagey about it.

115
00:04:38.640 --> 00:04:40.320
They're not confirming who's assigned to the

116
00:04:40.320 --> 00:04:42.970
mission. Back in 2018, they announced the

117
00:04:42.970 --> 00:04:45.250
cruise, then people got reassigned and things

118
00:04:45.250 --> 00:04:47.130
got complicated. It's all a bit of a mess

119
00:04:47.130 --> 00:04:50.050
really. But hey, at least astronaut Butch

120
00:04:50.050 --> 00:04:52.210
Wilmore said he'd ride on Starliner again,

121
00:04:52.770 --> 00:04:54.730
cuz he's confident they're Gonna fix all the

122
00:04:54.730 --> 00:04:57.530
issues. Gotta admire that kind of optimism

123
00:04:57.530 --> 00:04:59.810
right now.

124
00:05:00.050 --> 00:05:02.170
Let's jump into the future, like, way into

125
00:05:02.170 --> 00:05:05.170
the future. The Royal society in the UK

126
00:05:05.250 --> 00:05:07.080
just dropped a report called Speaker Space

127
00:05:07.320 --> 00:05:09.720
2075. And it's wild.

128
00:05:10.920 --> 00:05:13.040
We're talking asteroid mining, space

129
00:05:13.040 --> 00:05:15.240
factories, and even the big question, are we

130
00:05:15.240 --> 00:05:18.160
alone? The report envisions a new

131
00:05:18.160 --> 00:05:20.400
era of space activities that could totally

132
00:05:20.400 --> 00:05:23.000
reshape the world. Imagine clean energy

133
00:05:23.000 --> 00:05:25.400
beamed down to Earth from space. Robots

134
00:05:25.400 --> 00:05:27.200
recycling dead satellites and products

135
00:05:27.200 --> 00:05:29.720
labelled Made in space. Sounds like sci fi,

136
00:05:29.720 --> 00:05:32.680
right? But the report warns that the UK needs

137
00:05:32.680 --> 00:05:35.270
a clear plan to keep up, otherwise

138
00:05:35.510 --> 00:05:36.950
they might miss out on all these

139
00:05:36.950 --> 00:05:39.390
opportunities. They're saying this is as big

140
00:05:39.390 --> 00:05:42.230
as the Industrial Revolution. Think about it.

141
00:05:42.550 --> 00:05:45.310
Factories in microgravity making stuff we

142
00:05:45.310 --> 00:05:47.550
can't even make on Earth. Interplanetary

143
00:05:47.550 --> 00:05:49.990
space stations and even industries moving

144
00:05:49.990 --> 00:05:52.590
into orbit. Power hungry data farms could

145
00:05:52.590 --> 00:05:55.030
benefit from all that solar energy and free

146
00:05:55.030 --> 00:05:57.630
cooling up there. And get this, they're even

147
00:05:57.630 --> 00:06:00.310
talking about recycling space junk to reduce

148
00:06:00.310 --> 00:06:03.130
collision risks and prevent pollution. Makes

149
00:06:03.130 --> 00:06:04.810
sense, right? But it's not all sunshine and

150
00:06:04.810 --> 00:06:07.770
roses. The report also warns about potential

151
00:06:07.770 --> 00:06:09.850
conflicts in space over prime spots on

152
00:06:09.850 --> 00:06:12.530
planets, valuable orbits and radio

153
00:06:12.530 --> 00:06:15.090
frequencies. It's like the Wild west, but in

154
00:06:15.090 --> 00:06:17.970
space, ethical challenges are also on the

155
00:06:17.970 --> 00:06:20.490
horizon. What if we engineer bugs to make

156
00:06:20.490 --> 00:06:22.690
living tools on Mars, but they end up wiping

157
00:06:22.690 --> 00:06:25.130
out native microbes? And what happens when

158
00:06:25.130 --> 00:06:27.690
humans start being born on Mars? Deep stuff.

159
00:06:27.690 --> 00:06:30.380
Huh? Huh? Oh, and of course, the big one,

160
00:06:30.540 --> 00:06:33.300
alien life. The report says if there are

161
00:06:33.300 --> 00:06:35.300
aliens nearby, we'll probably know in the

162
00:06:35.300 --> 00:06:37.540
next 50 years. Let's hope it brings us

163
00:06:37.540 --> 00:06:39.700
together, not tears us apart. Fingers

164
00:06:39.700 --> 00:06:42.540
crossed. So

165
00:06:42.700 --> 00:06:44.780
that's your Astronomy Daily News for today.

166
00:06:45.100 --> 00:06:47.790
We looked at Titan's wobbly atmosphere, a,

167
00:06:47.740 --> 00:06:50.700
mega ancient galaxy, starliner's ongoing

168
00:06:50.700 --> 00:06:53.420
delays, and the Royal Society's peek into the

169
00:06:53.420 --> 00:06:55.990
future. Thanks for tuning in. I've been your
