00:00:06.960 --> 00:00:11.039
Coming up on Space Time, how black holes shape the Cosmos,

00:00:11.759 --> 00:00:15.560
NASA forced to end its maven Mars mission, and Planet

00:00:15.599 --> 00:00:19.120
Earth gets a rare blue micromoon. All that and more

6
00:00:19.199 --> 00:00:21.600
coming up on space Time.

7
00:00:22.719 --> 00:00:25.839
Welcome to Space Time with Stuart Gary.

8
00:00:41.880 --> 00:00:45.439
A new study has revealed how powerful jets generated by

9
00:00:45.439 --> 00:00:49.880
black holes have shaped the universe. The findings reported in

10
00:00:49.920 --> 00:00:53.560
the journal Nature Astronomy, based on measurements of the jets

11
00:00:53.560 --> 00:00:56.880
emanating from Signus x one system, made up of the

12
00:00:56.920 --> 00:01:00.960
first confirmed black hole and a blue supergiant star. The

13
00:01:01.000 --> 00:01:03.679
authors found that the power of the jets in Signus

14
00:01:03.880 --> 00:01:06.760
x one was equivalent to the power output of ten

15
00:01:06.879 --> 00:01:11.879
thousand sons. Black hole jets provide an important source of

16
00:01:11.920 --> 00:01:15.840
feedback to the surrounding environment, and they're critical to understanding

17
00:01:15.840 --> 00:01:20.159
the evolution of galaxies. Located some seven three hundred light

18
00:01:20.239 --> 00:01:23.159
years away, the black hole in Signus X one has

19
00:01:23.239 --> 00:01:27.040
around twenty one point two solar masses, while it's still

20
00:01:27.079 --> 00:01:31.040
a companion is a variable spertual type O blue supergiant

21
00:01:31.159 --> 00:01:34.560
of about forty solar masses the pair all but each

22
00:01:34.599 --> 00:01:37.879
other every five point six earth days at an average

23
00:01:37.920 --> 00:01:41.719
distance of zero point two astronomical units. That's about twenty

24
00:01:41.760 --> 00:01:44.200
percent of the distance between the Earth and the Sun.

25
00:01:44.799 --> 00:01:47.359
The Signus X one system appears to belong to a

26
00:01:47.400 --> 00:01:51.560
stellar association called Signus OB three, and that would mean

27
00:01:51.640 --> 00:01:55.680
Signus X one's probably around five million years old, and

28
00:01:56.000 --> 00:01:59.000
like its binary companion, was formed by a progenitor star

29
00:01:59.120 --> 00:02:02.040
that had more than what he saw the masses. These

30
00:02:02.079 --> 00:02:05.000
arise from gases being accreted onto the black hole from

31
00:02:05.040 --> 00:02:10.000
the Blue supergiant and then heated extremely high temperatures. To

32
00:02:10.080 --> 00:02:13.360
make their measurements, the authors used a radio telescope into

33
00:02:13.400 --> 00:02:17.840
ferometer into perometers link up mudible observatories around the planet,

34
00:02:17.919 --> 00:02:20.639
and this gave the astronomers the resolution they needed to

35
00:02:20.639 --> 00:02:23.639
measure the immense power being generated by the jets from

36
00:02:23.680 --> 00:02:26.719
the black hole, and the authors observed the black hole

37
00:02:26.840 --> 00:02:30.840
jets being buffeted by winds from the companion Bleue Supergiant

38
00:02:31.000 --> 00:02:33.520
as the black hole moved around it in its orbit,

39
00:02:33.680 --> 00:02:36.319
much like strong winds on Earth will push around water

40
00:02:36.319 --> 00:02:38.960
in a fountain. By knowing the power of the wind

41
00:02:39.039 --> 00:02:41.360
and measuring how much the jets were bent, the authors

42
00:02:41.360 --> 00:02:44.080
could determine the instantaneous power of the jets for the

43
00:02:44.159 --> 00:02:47.280
first time, and they were also able to determine the

44
00:02:47.319 --> 00:02:49.639
speed of the black hole jets to be about half

45
00:02:49.680 --> 00:02:51.800
that of the speed of light one hundred and fifty

46
00:02:51.840 --> 00:02:55.759
thousand kilometus per second, another measurement that had giant scientists

47
00:02:55.800 --> 00:02:56.479
for decades.

48
00:02:57.039 --> 00:02:58.039
The studies lead.

49
00:02:57.879 --> 00:03:01.360
Author, Steve Preibu from Curtain Universe, says he was able

50
00:03:01.400 --> 00:03:04.120
to make the measurements using a sequence of images of

51
00:03:04.159 --> 00:03:06.960
the dancing jets, a term he used to describe the

52
00:03:07.039 --> 00:03:10.199
jets movement patterns as they were repeatedly deflected in different

53
00:03:10.199 --> 00:03:14.280
directions by the blue super giants powerful stellar winds. Prabo

54
00:03:14.520 --> 00:03:17.680
says the measurements allowed the authors to understand what fraction

55
00:03:17.759 --> 00:03:20.199
of the energy released around the black hole was likely

56
00:03:20.240 --> 00:03:24.599
to be deposited in the surrounding environment, thereby changing that environment.

57
00:03:25.159 --> 00:03:28.199
Prey Billin colleagues found that around ten percent of the

58
00:03:28.319 --> 00:03:31.479
energy falling towards the black hole was being carried away

59
00:03:31.599 --> 00:03:35.400
by the jets. Previous methods could only measure the average

60
00:03:35.479 --> 00:03:39.159
jet power over thousands or even millions of years, preventing

61
00:03:39.199 --> 00:03:42.840
accurate comparisons with the X ray energy released instantaneously from

62
00:03:42.879 --> 00:03:46.479
the infalling matter. Rabou says astronomers can now use this

63
00:03:46.639 --> 00:03:49.840
measurement to anchor their understanding of the jets, whether they're

64
00:03:49.840 --> 00:03:52.719
formed from black holes ten or ten million times the

65
00:03:52.800 --> 00:03:54.759
mass of our Sun six one.

66
00:03:55.199 --> 00:03:58.719
It is the first widely accepted confirmed black holes within

67
00:03:58.759 --> 00:04:02.560
the astronomy community, and that was even a rager between

68
00:04:02.639 --> 00:04:06.479
Kipton and even talking back in the nineteen seventies if

69
00:04:06.520 --> 00:04:08.919
they thought the system could actually have a black hole.

70
00:04:09.360 --> 00:04:12.039
Over the last few decades, it taught us a lot

71
00:04:12.199 --> 00:04:15.759
regarding black holes and jet and how they can influence

72
00:04:15.919 --> 00:04:19.279
their surrounding and even though we understand a lot regarding

73
00:04:19.279 --> 00:04:22.639
the source, we'll have a few options. So that's when

74
00:04:22.759 --> 00:04:26.120
the three years ago we started looking into some of

75
00:04:26.160 --> 00:04:28.959
these high resolution radio images of the black hole, and

76
00:04:29.000 --> 00:04:31.360
that's when they saw that the jets were actually bending

77
00:04:31.519 --> 00:04:34.319
because of star that's orbiting the black hole, and it's

78
00:04:34.360 --> 00:04:37.240
got really massive strong winds that can actually push the

79
00:04:37.319 --> 00:04:40.240
jets around and make it appear as a dancing And

80
00:04:40.720 --> 00:04:44.839
we also found like it are to be the equivalent

81
00:04:44.879 --> 00:04:47.319
of ten thousand suns. And then the York they had

82
00:04:47.360 --> 00:04:50.000
like the key measurements of this source.

83
00:04:50.279 --> 00:04:55.040
Roughly speaking, about ten percent of the material falling onto

84
00:04:55.079 --> 00:04:57.639
the black hole is throwing back at again in the

85
00:04:57.680 --> 00:04:58.680
form of these jets.

86
00:04:59.000 --> 00:05:02.680
Yes, is actually a very important measurement. So black holes

87
00:05:02.720 --> 00:05:06.079
have something called as an energy budget, like how like

88
00:05:06.240 --> 00:05:09.480
how we budget our income into different things. The black

89
00:05:09.480 --> 00:05:12.160
hole also has called it an energy budget. So there

90
00:05:12.199 --> 00:05:14.759
is energy going to the black hole because the material

91
00:05:14.839 --> 00:05:16.680
is falling into the black hole. But then they can

92
00:05:16.720 --> 00:05:19.199
budget it too different things O Diferently, some of it

93
00:05:19.360 --> 00:05:22.079
can get eaten by the black holes or trying to

94
00:05:22.160 --> 00:05:27.839
understand percentage of the infalling heal or energy gets kind

95
00:05:27.879 --> 00:05:30.160
of judgeted to like a very important measurement. So that's

96
00:05:30.199 --> 00:05:33.279
what we found to be around ten percent. So in

97
00:05:33.480 --> 00:05:36.839
literature with an astronomy, because a number has been ad

98
00:05:36.879 --> 00:05:40.720
hoc assumptions, they've declomined that number in like literature, but

99
00:05:40.800 --> 00:05:44.079
there was never like a direct evidence of it. So

100
00:05:44.160 --> 00:05:46.000
this is the first time we have like a diferant

101
00:05:46.079 --> 00:05:47.439
observation evidence of it.

102
00:05:47.519 --> 00:05:50.839
Because all black holes are basically the same, you can

103
00:05:50.959 --> 00:05:55.079
use those observations to extrapolate onto other black holes as well,

104
00:05:55.240 --> 00:05:56.480
bigger ones and smaller ones.

105
00:05:56.759 --> 00:05:59.759
Very very true. Yes, So like I like to imagine,

106
00:05:59.839 --> 00:06:03.360
like imagine that using Earth, Moon and star the Sun.

107
00:06:03.560 --> 00:06:06.240
So we know the Moon goes around the Earth and

108
00:06:06.279 --> 00:06:08.920
then there is like orbital motion of the Moon around

109
00:06:08.959 --> 00:06:11.319
the Earth, and it can apply Settler's loss and you

110
00:06:11.360 --> 00:06:14.079
can actually take the same physics and scale it up

111
00:06:14.120 --> 00:06:18.000
to Earth and the Sun. Those like the masses are different.

112
00:06:18.000 --> 00:06:20.879
You're just scaling it up, and the same deeplarium laws

113
00:06:20.959 --> 00:06:23.759
apply when Earth goes around the Sun as when the

114
00:06:23.759 --> 00:06:26.040
Moon goes around the Sun. So similarly, you can take

115
00:06:26.040 --> 00:06:29.519
this ten person's energy budget off the black hole and

116
00:06:29.560 --> 00:06:31.920
scale it up to super massive black holes. And the

117
00:06:31.959 --> 00:06:35.399
reason that is very important is because in every galaxy

118
00:06:35.480 --> 00:06:37.240
at the center of it, there is a super massive

119
00:06:37.279 --> 00:06:39.800
black hole that can weigh a few millions to billion

120
00:06:39.879 --> 00:06:42.759
times the mass of the Sun. These jets are large,

121
00:06:42.839 --> 00:06:46.160
like very very large jets, and they're suggest from the

122
00:06:46.199 --> 00:06:49.759
super massive black holes can deposit lots of plasma and

123
00:06:49.879 --> 00:06:54.519
magnetic seals in the mediums between galaxies and surrounding galaxies,

124
00:06:54.759 --> 00:06:59.240
and that heavily, heavily influences how like galaxies and large

125
00:06:59.240 --> 00:07:02.360
scale structures, the universe evolves over time, so that in

126
00:07:02.439 --> 00:07:06.319
these large scale simulations. That energy budget of black hoes

127
00:07:06.399 --> 00:07:08.839
is like a tenable number that they play around with

128
00:07:08.959 --> 00:07:11.279
and then they set it to like ten percent because

129
00:07:11.319 --> 00:07:14.680
of their models. But our detection actually puts it on

130
00:07:14.839 --> 00:07:18.759
like very strong observational zoning and robusts.

131
00:07:18.800 --> 00:07:21.000
Now, how did you carry out the observations?

132
00:07:21.279 --> 00:07:24.680
So we use this few instruments called two instruments actually

133
00:07:24.680 --> 00:07:27.439
in our studies. So one is called the VOBA very

134
00:07:27.439 --> 00:07:32.079
Long Baseline interfometry and the other is called European VOBA realbi.

135
00:07:32.439 --> 00:07:36.079
So essentially these two telescopes are like lots of telescopes

136
00:07:36.199 --> 00:07:38.839
spread within a continent, as a VOBA is in the

137
00:07:39.000 --> 00:07:42.800
US and even is in the Europe and multiple telescopes

138
00:07:42.920 --> 00:07:46.240
spread across the continent. They work together and synthesize a

139
00:07:46.439 --> 00:07:50.879
very high resolution image in radio frequencies. So it's a

140
00:07:50.920 --> 00:07:55.079
slightly smaller version of the event horizon telescope that made

141
00:07:55.240 --> 00:07:58.959
image of the black hole in our galaxy and maybe

142
00:07:59.000 --> 00:08:02.519
seven like two grow it's a slightly smaller version of that.

143
00:08:02.639 --> 00:08:05.920
So the eventorizing telescope scales the size of the Earth.

144
00:08:06.000 --> 00:08:09.920
Our telescope ans the size of the continent. So we

145
00:08:10.040 --> 00:08:13.199
use those two instruments to make very high resolution images

146
00:08:13.279 --> 00:08:15.680
of the black hole jet and yeah, we were able

147
00:08:15.720 --> 00:08:18.360
to study it in very high detailed revolution detail.

148
00:08:18.439 --> 00:08:21.480
Do we know how the jets themselves? These beams of

149
00:08:21.600 --> 00:08:23.560
matter and energy coming out of the black holes?

150
00:08:23.600 --> 00:08:24.959
Do we know how they created?

151
00:08:25.160 --> 00:08:28.759
We had like theories on how black holes launched jets

152
00:08:28.800 --> 00:08:32.440
from like nineteen teventies and eighties. So the black hole

153
00:08:32.879 --> 00:08:35.600
has materials falling toward bit because the black hole is

154
00:08:35.600 --> 00:08:38.480
a very dense point in space. And the point about

155
00:08:38.519 --> 00:08:40.559
black hole being is that they can also spend. So

156
00:08:40.639 --> 00:08:44.080
because they spin, they can warp and they can twist

157
00:08:44.159 --> 00:08:46.960
to space them around them. So we call that frame dragon.

158
00:08:48.000 --> 00:08:51.840
So because of that effects, the black hole tends to

159
00:08:52.000 --> 00:08:55.600
warp and twist all the magnetic field in its vicinity

160
00:08:55.879 --> 00:08:59.759
into like a helical field along the axis that it

161
00:09:00.399 --> 00:09:03.799
and just magnetic fields are responsible for launching of the jets.

162
00:09:03.919 --> 00:09:07.559
So essentially it paps into the spin energy of the

163
00:09:07.559 --> 00:09:10.120
black hole to launch the jets to create the magnetic

164
00:09:10.159 --> 00:09:11.399
fields which launches the jet.

165
00:09:11.440 --> 00:09:14.080
And you're able to confirm also the speed at which

166
00:09:14.080 --> 00:09:15.840
the jets are moving out from the black hole.

167
00:09:16.000 --> 00:09:19.120
Yes, so because the jets were bending, it opened bending,

168
00:09:19.399 --> 00:09:21.720
it opened up like a new way of studying the

169
00:09:21.720 --> 00:09:25.440
black hole jet, and that this new method that enabled

170
00:09:25.519 --> 00:09:27.480
us to measure the speed of the jet as well,

171
00:09:27.519 --> 00:09:29.720
So we found it to be traveling at like half

172
00:09:29.759 --> 00:09:31.919
the speed of light. So that's like a lot of

173
00:09:32.000 --> 00:09:35.320
materials carried away from the black holes at the speed

174
00:09:35.320 --> 00:09:38.320
of light and hence producing the energy equalent.

175
00:09:39.279 --> 00:09:42.360
The jets that we to set the scale the jets

176
00:09:42.360 --> 00:09:44.919
that we detect to the black hole itself is around

177
00:09:44.960 --> 00:09:48.480
one hundred kilometers, so twenty one times the mass of

178
00:09:48.519 --> 00:09:51.840
the Sun compressed to a size or one hundred kilometers

179
00:09:51.840 --> 00:09:54.080
and the jets launched from the black holes fand the

180
00:09:54.120 --> 00:09:58.639
size of OURSELT system to set things, yeah, to set

181
00:09:58.679 --> 00:10:00.039
the scene for the system.

182
00:10:00.200 --> 00:10:01.759
Like to see this research go next.

183
00:10:02.000 --> 00:10:05.440
So there are a few other systems where there are

184
00:10:05.559 --> 00:10:09.639
similar massive stars orbiting either a black hole or a

185
00:10:09.720 --> 00:10:13.559
neutron start. I think Significs one is probably the easiest

186
00:10:13.720 --> 00:10:16.279
low standing fruits that you can apply this technique too.

187
00:10:16.759 --> 00:10:20.399
But there are other systems of similar massive strong wind

188
00:10:20.480 --> 00:10:23.120
and black hole jets from like either black holes and

189
00:10:23.240 --> 00:10:26.159
jets neutron starts that you can apply similar techniques to.

190
00:10:26.320 --> 00:10:30.200
So Amaha, let's look at similar other systems to see

191
00:10:30.240 --> 00:10:33.600
as we can also estimate their powers and just feed

192
00:10:33.720 --> 00:10:35.279
another system parameters.

193
00:10:35.440 --> 00:10:40.000
Let's doctor Steve Prebu from Kurtney University, and this is

194
00:10:40.000 --> 00:10:43.879
space Time. Still the calm. That's a force to end.

195
00:10:43.919 --> 00:10:47.080
It's Marvin mission to Mars and planet Earth gets a

196
00:10:47.159 --> 00:10:50.279

224
00:12:32.200 --> 00:12:35.240
to shut down It's a mavon mission orbiting Mars following

225
00:12:35.240 --> 00:12:39.000
a mysterious failure aboard the spacecraft back in December. The

226
00:12:39.080 --> 00:12:42.360
probe suddenly went silent on December the sixth as it

227
00:12:42.440 --> 00:12:46.159
was passing behind Mars. Attempts to re establish the signal

228
00:12:46.200 --> 00:12:48.639
after it came around the red planet slim back into

229
00:12:48.720 --> 00:12:52.360
view of the Earth were unsuccessful. The Mars Atmosphere and

230
00:12:52.440 --> 00:12:56.279
Volatile Evolution, or MAVEN spacecraft was the first mission devoted

231
00:12:56.320 --> 00:13:00.440
to observing the Martian atmosphere and evolution. It's been orbiting

232
00:13:00.440 --> 00:13:04.559
Mars for eleven years. The agency convened an anomaly Review

233
00:13:04.559 --> 00:13:07.639
Board in February to try and evaluate recovery efforts and

234
00:13:07.720 --> 00:13:11.279
assess the spacecraft's probable current state, and the review boards

235
00:13:11.279 --> 00:13:15.639
now determined the maven's spacecraft cannot be saved, it's not recoverable,

236
00:13:15.720 --> 00:13:18.600
and it's no longer capable of performing its science and

237
00:13:18.679 --> 00:13:23.279
data relay missions. Telemetry from MAVEN prior to the spacecraft's

238
00:13:23.279 --> 00:13:26.639
passage behind Mars in December showed all its subsystems were

239
00:13:26.679 --> 00:13:31.279
working nominally, but after the spacecraft emerged, NASA's Deep Space

240
00:13:31.320 --> 00:13:35.440
Communications network did not receive a signal. A brief fragment

241
00:13:35.480 --> 00:13:38.840
of telemetry data from analysis of radio signals recorded by

242
00:13:38.919 --> 00:13:42.279
the Deep Space network's open loop receivers indicated the probe

243
00:13:42.360 --> 00:13:45.120
wasn't a safe mode, but was rotating at an unusually

244
00:13:45.200 --> 00:13:47.960
high rate when it emerged from behind Mars, indicating a

245
00:13:48.039 --> 00:13:52.399
disruption in maven's orbital trajectory. The review boards concluded that

246
00:13:52.519 --> 00:13:55.399
due to this rotation the batteries on the spacecraft had

247
00:13:55.440 --> 00:13:58.720
now drained, causing the communication system to lose power and

248
00:13:58.759 --> 00:14:03.320
rendering maven As unrecoverable. Now, these plminary findings don't address

249
00:14:03.320 --> 00:14:06.639
a potential root cause for the anomaly that's still being investigated.

250
00:14:07.120 --> 00:14:08.279
The review boards.

251
00:14:08.000 --> 00:14:10.960
Now expected to provide its final report later this year.

252
00:14:12.159 --> 00:14:15.200
The science may have been gathered has provided valuable information

253
00:14:15.240 --> 00:14:18.399
about the kind of radiation protection and safety measures will

254
00:14:18.440 --> 00:14:20.960
be needed before the first humans are sent to the

255
00:14:21.000 --> 00:14:24.879
Red Planet sometime in the next decade. The launched back

256
00:14:24.879 --> 00:14:28.200
in November twenty thirteen, The mayn mission explored the Red

257
00:14:28.240 --> 00:14:32.399
Planet's upper atmosphere it's a hoosphere, and the interactions between

258
00:14:32.399 --> 00:14:35.120
the atmosphere and the Sun in order to investigate the

259
00:14:35.120 --> 00:14:39.919
loss of the Martian atmosphere into space. Understanding atmospheric loss

260
00:14:40.120 --> 00:14:43.519
give scientists insights into the history of the planet's atmosphere

261
00:14:43.519 --> 00:14:48.200
and climate, liquid water, and planetary habitability. Mayven discovered that

262
00:14:48.279 --> 00:14:52.960
the erosion of the Martian atmosphere increases significantly during solar storms.

263
00:14:53.679 --> 00:14:57.200
Scientists studied how the solar wind that's the constant stream

264
00:14:57.200 --> 00:15:00.679
of charged particles flowing out from the Sun, and storms,

265
00:15:00.799 --> 00:15:04.600
which are more powerful bursts of particles continuously strip the

266
00:15:04.600 --> 00:15:08.720
red planet's atmosphere, and this provides a key insight into

267
00:15:08.759 --> 00:15:12.159
how Mars was transformed from a warm, wet world potentially

268
00:15:12.200 --> 00:15:15.919
capable of supporting life into the sterile, freeze dried desert

269
00:15:16.000 --> 00:15:20.000
it is today, and Maybeon was the only spacecraft that

270
00:15:20.080 --> 00:15:23.200
could simultaneously take measurements of both the Sun and the

271
00:15:23.240 --> 00:15:24.919
Martian atmospheric response.

272
00:15:25.559 --> 00:15:27.360
It discovered several types.

273
00:15:27.080 --> 00:15:30.720
Of Martian arore that light up when energetic particles plunge

274
00:15:30.759 --> 00:15:34.360
into the planet's atmosphere, bombarding gases and making them glow.

275
00:15:35.080 --> 00:15:38.240
Maybon showed that the protons create new kinds of arorare

276
00:15:38.440 --> 00:15:42.200
on Mars. On Earth, proton aurore only occur in very

277
00:15:42.200 --> 00:15:44.799
small regions near the poles, whereas on Mars they can

278
00:15:44.799 --> 00:15:48.279
occur anywhere. To better understand how Mars lost most of

279
00:15:48.320 --> 00:15:51.799
its atmosphere, May even measured atmosphere sputtering for the first

280
00:15:51.799 --> 00:15:55.200
time on any planet. It observed argon, which is a

281
00:15:55.240 --> 00:15:58.440
noble gas, meaning it rarely reacts with other constituents in

282
00:15:58.480 --> 00:16:02.080
the Martian atmosphere. The only significant way argon can be

283
00:16:02.159 --> 00:16:06.120
removed is by atmosphere spattering, a process where ions crash

284
00:16:06.159 --> 00:16:08.799
into the Martian atmosphere at high enough speeds so that

285
00:16:08.840 --> 00:16:12.080
they splash gas molecules out of the atmosphere, much like

286
00:16:12.159 --> 00:16:16.159
doing a cannonball into a pool. Astronomers used eleven years

287
00:16:16.159 --> 00:16:19.200
of Marvin data to show the presence of sputted argon

288
00:16:19.279 --> 00:16:22.559
at high altitudes in the exact locations where the energetic

289
00:16:22.600 --> 00:16:26.600
particles crashed into the atmosphere, showing sputtering in real time.

290
00:16:27.679 --> 00:16:30.519
In twenty eighteen, this series of Martian dust storms created

291
00:16:30.519 --> 00:16:33.879
a dust cloud so large it enveloped the entire planet.

292
00:16:34.519 --> 00:16:37.759
Mayven then studied how this global dust storm affected the

293
00:16:37.840 --> 00:16:41.200
upper Martian atmosphere in order to understand how these events

294
00:16:41.279 --> 00:16:44.919
affected the escape of water into space. It confirmed that

295
00:16:45.000 --> 00:16:48.240
heating from dust storms can loft water molecules far higher

296
00:16:48.240 --> 00:16:51.240
into the atmosphere than usual, leading to a sudden surge

297
00:16:51.320 --> 00:16:55.159
in water lost to space, and it doesn't end there.

298
00:16:55.399 --> 00:16:58.879
Mayven also contributed to NASA's efforts to observe the interstallar

299
00:16:58.960 --> 00:17:02.320
comet three I outlus. Over the course of ten days

300
00:17:02.399 --> 00:17:05.920
last year, Mayven observed three I outlets, taking multiple images

301
00:17:05.960 --> 00:17:09.599
of the comet in modible wavelengths, including high resolution ultraviolet

302
00:17:09.640 --> 00:17:13.359
images to identify the hydrogen coming from the comet. By

303
00:17:13.400 --> 00:17:16.359
stating a combination of these images, scientists can identify a

304
00:17:16.440 --> 00:17:20.480
variety of molecules to better understand the commet's composition and history.

305
00:17:21.640 --> 00:17:25.319
During the mission's lifetime, Mayven science team produced more than

306
00:17:25.359 --> 00:17:29.680
eight hundred publications and additional publications in the works now

307
00:17:29.799 --> 00:17:33.559
as the backlog of data is processed. In addition to

308
00:17:33.599 --> 00:17:36.359
its science work, Maven was also a key part of

309
00:17:36.480 --> 00:17:40.480
NASA's Mars Relay network, communicating data from the Mars rovers

310
00:17:40.519 --> 00:17:43.559
back to Earth. In fact, it holds the Solar System

311
00:17:43.640 --> 00:17:46.240
record for the most data relayed from another planet in

312
00:17:46.279 --> 00:17:49.920
a single day. And so it's farewell to Maven, a

313
00:17:50.000 --> 00:17:52.079
spacecraft which will be sorely missed.

314
00:17:52.839 --> 00:17:54.160
This is space time.

315
00:17:54.880 --> 00:17:57.960
Still the comme planet Earth gets a rare blue micromoon,

316
00:17:58.160 --> 00:18:02.079
and later in the science report, paleontologists of identified fossils

317
00:18:02.079 --> 00:18:05.440
of a new species of raptorlike dinosaur in South America.

318
00:18:05.960 --> 00:18:08.759
All that and more still to come on space time,

319
00:18:24.359 --> 00:18:28.720
skywatchers have just experienced a rare blue micromon. The title

320
00:18:28.759 --> 00:18:31.880
comes from the fact that well it's a blue moon, Monjeet.

321
00:18:31.880 --> 00:18:34.359
That's got nothing to do with the moon's color. It

322
00:18:34.480 --> 00:18:37.400
refers to the rare event when a second full moon

323
00:18:37.519 --> 00:18:41.519
occurs in the same calendar month. However, technically that's not

324
00:18:41.599 --> 00:18:45.400
quite accurate. In astronomical terms, a blue moon occurs when

325
00:18:45.400 --> 00:18:48.359
there's an extra full moon in an astronomical season of

326
00:18:48.440 --> 00:18:52.160
three months, a period between equinarchs and solstices, which would

327
00:18:52.200 --> 00:18:55.319
normally only have three full moons, and due to the

328
00:18:55.319 --> 00:18:58.200
way the lunar cycle aligns with the solar calendar, a

329
00:18:58.279 --> 00:19:02.559
season may occasionally have four full moons, and so the

330
00:19:02.559 --> 00:19:05.559
third full moon in that four moon sequence is what's

331
00:19:05.599 --> 00:19:07.039
referred to as a blue moon.

332
00:19:08.279 --> 00:19:08.440
Now.

333
00:19:08.480 --> 00:19:11.119
As for the micromoon part of the title, well, it

334
00:19:11.240 --> 00:19:14.240
refers to the Moon being at Apergee, that's its most

335
00:19:14.240 --> 00:19:17.920
distant orbital position from the Earth. The Moon's orbit around

336
00:19:17.920 --> 00:19:21.400
the Earth isn't circular, but elongated, and when the Moon's

337
00:19:21.400 --> 00:19:23.640
at its furthest from the Earth, it looks an it's

338
00:19:23.720 --> 00:19:26.599
a bits a bit smaller and dimmer than normal, hence

339
00:19:26.640 --> 00:19:30.240
the term micromon. Now, on this occasion, at Apergee, the

340
00:19:30.279 --> 00:19:32.759
Moon was some four hundred and six one hundred and

341
00:19:32.759 --> 00:19:36.319
thirty five kilometers away. That compares to the average Earth

342
00:19:36.359 --> 00:19:39.000
moon distance of three hundred and eighty four thousand, four

343
00:19:39.079 --> 00:19:43.319
hundred kilometers. The opposite is the much heralded supermoon that's

344
00:19:43.359 --> 00:19:45.920
when a full moon happens while it's orbit's closest to

345
00:19:46.000 --> 00:19:49.559
the Earth called perigee, and the most recent supermoon was

346
00:19:49.599 --> 00:19:52.160
back on December the fourth last year, when the Moon

347
00:19:52.279 --> 00:19:54.599
was just three undred and sixty two three hundred and

348
00:19:54.640 --> 00:19:55.839
twelve kilometers away.

349
00:19:56.359 --> 00:19:56.920
Now, for the.

350
00:19:56.920 --> 00:20:01.079
Technically minded, during the recent micromoon event, most celestial neighbor

351
00:20:01.119 --> 00:20:04.119
appeared to be about six percent smaller and ten percent

352
00:20:04.200 --> 00:20:07.200
timm than that of an average full moon. Of course,

353
00:20:07.200 --> 00:20:10.039
in real life that difference is extremely subtle. Most people

354
00:20:10.039 --> 00:20:12.559
wouldn't have noticed it, and even if you knew, you

355
00:20:12.640 --> 00:20:15.359
probably would have needed measuring equipment to tell the difference

356
00:20:15.400 --> 00:20:15.799
for sure.

357
00:20:16.720 --> 00:20:18.240
This space time.

358
00:20:33.799 --> 00:20:35.480
And time that to take a brief look at some

359
00:20:35.480 --> 00:20:37.839
of the other stories making news and science this week

360
00:20:37.960 --> 00:20:42.319
with a science report, the World Meteorological Organization has again

361
00:20:42.400 --> 00:20:45.279
confirmed that an El Nino climate event is expected to

362
00:20:45.319 --> 00:20:48.759
develop this month, and they now say it's expected to

363
00:20:48.839 --> 00:20:52.440
last until at least the Southern Hemisphere spring. An El

364
00:20:52.519 --> 00:20:56.240
Nino event can bring hotter, dry conditions across much of Australia,

365
00:20:56.400 --> 00:20:59.640
driven by warming sea surface temperatures in the tropical easter.

366
00:21:00.839 --> 00:21:04.200
The Wood Meteorological Organization says there's now a ninety percent

367
00:21:04.400 --> 00:21:07.240
certainty that this patent will develop in coming months, bringing

368
00:21:07.240 --> 00:21:10.680
an increased risk of extreme climate and weather events across a.

369
00:21:10.640 --> 00:21:11.839
Large part of the world.

370
00:21:13.440 --> 00:21:15.400
A new study claims that up to one in six

371
00:21:15.480 --> 00:21:19.039
cases of COVID nineteen might have resulted in patients suffering

372
00:21:19.039 --> 00:21:21.960
long COVID. The findings, reported in the Journal of the

373
00:21:22.000 --> 00:21:25.440
American Medical Association, investigated some four hundred and fifty eight

374
00:21:25.480 --> 00:21:29.160
thousand patients with COVID nineteen across fifty eight hospitals in

375
00:21:29.200 --> 00:21:32.880
the United States, and the authors found long COVID occurred

376
00:21:32.880 --> 00:21:36.160
in sixteen point two eight percent of all cases. They

377
00:21:36.200 --> 00:21:38.759
also found that almost ninety percent of these long COVID

378
00:21:38.799 --> 00:21:42.200
cases were representative of chronic conditions, meaning that nine to

379
00:21:42.319 --> 00:21:44.960
ten people with the condition had it for extended periods

380
00:21:45.000 --> 00:21:48.440
of time, usually six months or longer. The World Health

381
00:21:48.519 --> 00:21:51.799
Organization says over seven point one million people have been

382
00:21:51.880 --> 00:21:55.000
killed by the COVID nineteen coronavirus since it was first

383
00:21:55.079 --> 00:21:58.680
detected among workers at China's Wuhan Institute of Virology back

384
00:21:58.720 --> 00:22:03.039
in September twenty nine, twenty eight thousand deaths were caused

385
00:22:03.039 --> 00:22:07.160
by the virus in Australia. The Lancet Medical Journal estimates

386
00:22:07.200 --> 00:22:09.480
that the true global death toll is likely to be

387
00:22:09.519 --> 00:22:12.440
more than eighteen million, with over three quarters of a

388
00:22:12.480 --> 00:22:18.359
billion confirm cases globally. Paleontologists of identified fossils from a

389
00:22:18.400 --> 00:22:23.279
new species of raptorlike dinosaur uncovered in Patagonia. A report

390
00:22:23.319 --> 00:22:26.519
in the Journal of Vertebrate Paleontology claims the three met

391
00:22:26.519 --> 00:22:29.240
a long fish eating archosaur would have behaved a lot

392
00:22:29.359 --> 00:22:32.920
like modern day herons. The dinosaur has been named kank

393
00:22:33.039 --> 00:22:38.039
australas it was identified based on teeth vertebran toeburns. It's

394
00:22:38.119 --> 00:22:41.000
related to a family of small to medium sized Therapi

395
00:22:41.160 --> 00:22:44.680
dinosaurs have been discovered from the late Cretaceous period in Australia,

396
00:22:44.839 --> 00:22:49.559
South America, Antarctica, and Madagascar. It lived more than seventy

397
00:22:49.640 --> 00:22:53.000
million years ago in the landscape of meandering rivers and

398
00:22:53.039 --> 00:22:56.759
streams with seasonal ponds inhabited by aquatic plants such as

399
00:22:56.839 --> 00:23:02.519
water lilies and animals including fish, insects, oluscs. A new

400
00:23:02.559 --> 00:23:06.000
study has shown that many so called anti vaxxes eventually

401
00:23:06.160 --> 00:23:10.039
changed their mind get the JAB after all. A report

402
00:23:10.160 --> 00:23:13.359
by researchers at Imperial College London found that nearly two

403
00:23:13.480 --> 00:23:16.880
thirds of people who initially expressed reservations about the COVID

404
00:23:16.960 --> 00:23:21.680
nineteen vaccination were eventually vaccinated during the campaign. The Skeptics

405
00:23:21.759 --> 00:23:25.519
timendum says the study found that reluctance was heist early

406
00:23:25.559 --> 00:23:29.240
in the campaign. He says, in January twenty twenty one,

407
00:23:29.359 --> 00:23:33.319
eight percent of respondents still expressed doubts about vaccination, but

408
00:23:33.519 --> 00:23:36.119
by early twenty twenty two that figure had fallen to

409
00:23:36.160 --> 00:23:37.400
only around one percent.

410
00:23:37.720 --> 00:23:39.759
Basically, it's saying that a lot of people who were

411
00:23:39.799 --> 00:23:43.079
hesitant to get vaccinated when the COVID outbreak first occurred

412
00:23:43.240 --> 00:23:46.039
later when and got vaccinated, they actually looked at a

413
00:23:46.240 --> 00:23:48.559
huge number of people, over a million people. They had

414
00:23:48.599 --> 00:23:50.599
records to say, you know, obviously they've had a record

415
00:23:50.680 --> 00:23:52.599
for people who have been vaccinated. They looked at those

416
00:23:52.599 --> 00:23:55.160
who hadn't been vaccinated from the first outbreak and who

417
00:23:55.200 --> 00:23:57.559
later did get vaccinated. So I was saying in January

418
00:23:57.559 --> 00:23:59.920
twenty twenty one to eight percent of respondents to the

419
00:24:00.279 --> 00:24:03.119
Things expressed doubts, but by early twenty twenty two that

420
00:24:03.400 --> 00:24:06.960
doubt figure has fallen to one percent. In any vaccination

421
00:24:07.400 --> 00:24:09.839
population profile, you're going to get a majority of people

422
00:24:09.839 --> 00:24:12.799
are vaccinated. They understand it, it's worthwhile, they understand it

423
00:24:12.799 --> 00:24:14.799
has proven benefit. And you get a small percentage of

424
00:24:14.799 --> 00:24:17.759
people who can't get vaccinated because they're medically compromised. You

425
00:24:17.799 --> 00:24:20.319
get the people who are hesitant. Oh this I don't know.

426
00:24:20.480 --> 00:24:23.680
And they suggested that people are hesitant for various reasons.

427
00:24:23.680 --> 00:24:25.960
There's one survey is that a look that said a

428
00:24:26.000 --> 00:24:28.119
lot of women are hesitan because they don't know what's

429
00:24:28.119 --> 00:24:29.799
in them, or they think it's going to affect when

430
00:24:29.880 --> 00:24:32.559
personally like the ability they have babies, that sort of thing.

431
00:24:32.599 --> 00:24:34.720
Little kids don't think that they don't like needles, And

432
00:24:34.720 --> 00:24:36.519
I say, men don't laughing because they don't think it's

433
00:24:36.519 --> 00:24:38.799
a bigger problem is being made out to be. So

434
00:24:39.240 --> 00:24:41.640
a lot of the people who are hesitant eventually do

435
00:24:41.680 --> 00:24:43.960
get vaccinated. So there's harage number of people who don't

436
00:24:43.960 --> 00:24:46.799
get vaccinated. Do they still also have that other little

437
00:24:46.799 --> 00:24:48.920
cohort of the population who are the anti vaxxis And

438
00:24:49.000 --> 00:24:50.480
it doesn't matter what you say to them or what

439
00:24:50.519 --> 00:24:53.039
evidence you put forward, they won't get vaccinated. And they

440
00:24:53.279 --> 00:24:57.599
sadly encourage others by spreading fear and misunderstanding and misinformation

441
00:24:57.759 --> 00:25:00.400
about what vaccinations needs and what it can do. Why

442
00:25:00.519 --> 00:25:02.759
because they're just pain in the backside how much?

443
00:25:02.799 --> 00:25:05.519
And is a problem of journals like well, in this

444
00:25:05.599 --> 00:25:08.960
case the Lancet Medical Journal, they allowed Wakefield and people

445
00:25:09.160 --> 00:25:12.240
like him to spread their lives for years.

446
00:25:12.519 --> 00:25:14.920
Yes, yeah, I mean it's still just a popular press

447
00:25:14.920 --> 00:25:17.680
on the TV shows and think the Lancer I recognized

448
00:25:18.039 --> 00:25:18.720
learned the journal.

449
00:25:18.759 --> 00:25:21.559
It was one decade before the Lancet retracted the story

450
00:25:21.640 --> 00:25:22.880
even though they knew what was wrong.

451
00:25:23.000 --> 00:25:25.480
Yes, they need took a helmibalone time to do that.

452
00:25:25.599 --> 00:25:28.279
Andrew Wakefield and a number of other people wrote had

453
00:25:28.279 --> 00:25:31.160
an article suggesting there might be issues with the MMR,

454
00:25:31.279 --> 00:25:34.240
the Measles Month rebella vaccine, the fact that Andrew Wakefield

455
00:25:34.279 --> 00:25:36.640
was working on an alternative vaccine. It was decided the

456
00:25:36.640 --> 00:25:39.599
point they had issues with the vaccines. Wakefield then said

457
00:25:39.640 --> 00:25:41.160
in publicity for this thing, and there's a lot of

458
00:25:41.160 --> 00:25:44.279
publicity that the MMR vaccine can lead to autism. So

459
00:25:44.319 --> 00:25:46.480
a lot of parents, especially in the UK Wakefield work

460
00:25:46.559 --> 00:25:49.119
stopped vaccinating and then some of their fire there's outbreaks

461
00:25:49.160 --> 00:25:52.200
of measles, mumps and rebella, which which can be fatal.

462
00:25:52.319 --> 00:25:54.559
So because of this guy making these claims that it

463
00:25:54.559 --> 00:25:58.160
could lead to autism, thoroughly debunk no foundation for the theory.

464
00:25:58.240 --> 00:26:01.319
It's been so widely tested in them if they tested

465
00:26:01.319 --> 00:26:03.119
a million people or something, the hell of a lot

466
00:26:03.119 --> 00:26:05.079
of people, there's no evidence at all that this has

467
00:26:05.119 --> 00:26:08.640
an impact on autism. But the papers covered. The Lancet

468
00:26:09.039 --> 00:26:11.440
had published the original paper, most of the people who

469
00:26:11.440 --> 00:26:13.839
were co authors on the paper withdrew themselves and they

470
00:26:13.880 --> 00:26:16.640
realized what Wakefield was doing that the Landsort didn't want

471
00:26:16.680 --> 00:26:19.319
to withdraw the article on works not for at about

472
00:26:19.359 --> 00:26:22.039
ten years or so. Wakefield was eventually struck off the

473
00:26:22.079 --> 00:26:24.039
list of doctors went to America, where of course they

474
00:26:24.119 --> 00:26:25.960
made a fortune and has become a marker to the

475
00:26:26.000 --> 00:26:28.119
cause of the anti vaxis. And the trouble is the

476
00:26:28.119 --> 00:26:30.279
ones who suffer most of all are those people who

477
00:26:30.279 --> 00:26:32.960
are medically compromised. You need a large percentage of the

478
00:26:33.000 --> 00:26:36.640
population to be vaccinated. Ninety five percent is basically it,

479
00:26:36.640 --> 00:26:38.799
which just leaves that small cohort of people who can't

480
00:26:38.799 --> 00:26:39.480
get vaccinated.

481
00:26:39.559 --> 00:26:41.799
And here in Australia, now there are some places whereas

482
00:26:41.839 --> 00:26:43.279
few as eighty percent of the people have.

483
00:26:43.319 --> 00:26:46.640
Vaccinated someplaces where's down to sixty percent. Wow, especially in

484
00:26:46.680 --> 00:26:49.880
the sort of freethinking liberal hippies of the areas. Yeah,

485
00:26:50.160 --> 00:26:51.920
with ever Byron base of the areas. That's sort of

486
00:26:51.920 --> 00:26:53.559
think in a lot of places in the world where

487
00:26:53.599 --> 00:26:55.720
these people having a big impact is currently seeing the

488
00:26:55.799 --> 00:26:58.599
rise of measles cases in the US and the UK

489
00:26:58.680 --> 00:27:01.839
and Europe and Australia because of the low vaccination rate.

490
00:27:02.000 --> 00:27:04.720
It kills hundreds of thousands of people every year, especially

491
00:27:04.759 --> 00:27:07.519
in third world countries, and it's all because of people

492
00:27:07.519 --> 00:27:10.839
who are anti vex influencing people who are hesitant about

493
00:27:10.920 --> 00:27:13.200
vaccimation for whatever reason. In the ones in trap of

494
00:27:13.200 --> 00:27:14.839
those who can't be vaccinated.

495
