for broadcast on the 15th of January


00:00:05.560 --> 00:00:09.150
2025 coming up on SpaceTime could dark


00:00:09.160 --> 00:00:10.990
matter have shaped one of the Milky Way


00:00:11.000 --> 00:00:14.310
Galaxy Stellar streams our sun emits


00:00:14.320 --> 00:00:16.870
three more powerful solar flares all on


00:00:16.880 --> 00:00:19.429
the same day and planet Earth


00:00:19.439 --> 00:00:21.830
experiences a spectacular quadrantic


00:00:21.840 --> 00:00:24.589
meteor shower all that and more coming


00:00:24.599 --> 00:00:26.790
up on


00:00:26.800 --> 00:00:29.990
SpaceTime welcome to SpaceTime with

00:00:46.039 --> 00:00:48.790
Gary physicists have proposed a solution


00:00:48.800 --> 00:00:51.750
to a-standing puzzle surrounding the gd1


00:00:51.760 --> 00:00:53.990
Stellar stream one of the best studied


00:00:54.000 --> 00:00:56.310
streams of stars within the Milky Ways


00:00:56.320 --> 00:00:59.229
Galactic Halo the new research reported


00:00:59.239 --> 00:01:01.349
in the Astro physical Journal letters


00:01:01.359 --> 00:01:03.549
proposes that a core collapsing self-


00:01:03.559 --> 00:01:06.030
interacting Dark Matter sub Halo that's


00:01:06.040 --> 00:01:07.950
a smaller satellite Halo within the


00:01:07.960 --> 00:01:10.230
galactic Halo could be responsible for


00:01:10.240 --> 00:01:12.109
the strange spur and GAP features


00:01:12.119 --> 00:01:14.990
observed in the gd1 Stellar stream a


00:01:15.000 --> 00:01:16.830
stellar stream is a group of stars


00:01:16.840 --> 00:01:18.950
moving collectively along a shed


00:01:18.960 --> 00:01:21.710
trajectory a gap refers to a localized


00:01:21.720 --> 00:01:23.950
under density of stars along the stream


00:01:23.960 --> 00:01:26.350
while a Spur is an overdensity of stars


00:01:26.360 --> 00:01:28.230
extending outwards from the main body of


00:01:28.240 --> 00:01:30.429
the stream since star Dark Matter


00:01:30.439 --> 00:01:32.350
governs the motion of Stellar streams


00:01:32.360 --> 00:01:34.190
astronomers can use these streams to


00:01:34.200 --> 00:01:36.030
trace invisible dark matter in the


00:01:36.040 --> 00:01:38.389
galaxy and this new research could have


00:01:38.399 --> 00:01:40.190
significant implications for


00:01:40.200 --> 00:01:41.510
understanding the properties of Dark


00:01:41.520 --> 00:01:44.109
Matter throughout the Universe the mky


00:01:44.119 --> 00:01:46.709
ways Galactic Halo a roughly spherical


00:01:46.719 --> 00:01:48.830
region surrounding the Galaxy contain


00:01:48.840 --> 00:01:50.950
star matter and extends well beyond the


00:01:50.960 --> 00:01:53.670
Galaxy's visible Edge astronomers


00:01:53.680 --> 00:01:55.030
discovered that the spur and GAP


00:01:55.040 --> 00:01:57.469
features of the gd1 Stellar stream can't


00:01:57.479 --> 00:01:59.350
easily be attributed to gravitational


00:01:59.360 --> 00:02:01.630
influence of known globular clusters or


00:02:01.640 --> 00:02:04.310
satellite galaxies but these features


00:02:04.320 --> 00:02:06.109
might be explained by an unknown


00:02:06.119 --> 00:02:09.309
perturbing object such as a sub Halo the


00:02:09.319 --> 00:02:11.110
thing is the object's density would need


00:02:11.120 --> 00:02:13.030
to be significantly higher than what's


00:02:13.040 --> 00:02:14.990
predicted by traditional cold Dark


00:02:15.000 --> 00:02:17.949
Matter subhalos the study's lead author


00:02:17.959 --> 00:02:19.470
hio youu from the University of


00:02:19.480 --> 00:02:21.470
California Riverside says that these


00:02:21.480 --> 00:02:23.390
typically lack the sorts of densities


00:02:23.400 --> 00:02:24.910
needed to produce the distinctive


00:02:24.920 --> 00:02:28.030
features observed in the gd1 Stream


00:02:28.040 --> 00:02:30.190
however the research demonstrates that a


00:02:30.200 --> 00:02:32.150
collapsing self-interacting Dark Matter


00:02:32.160 --> 00:02:34.270
subhalo could achieve the necessary


00:02:34.280 --> 00:02:37.150
density now such a compact subhalo would


00:02:37.160 --> 00:02:38.910
need to be dense enough to exert the


00:02:38.920 --> 00:02:40.790
sorts of gravitational influence


00:02:40.800 --> 00:02:42.670
required to account for the observed


00:02:42.680 --> 00:02:45.869
perturbations in the gd1 Stream mind you


00:02:45.879 --> 00:02:48.229
scientists have no idea what dark matter


00:02:48.239 --> 00:02:51.630
is it can't be directly seen they know


00:02:51.640 --> 00:02:53.390
it exists because they can see its


00:02:53.400 --> 00:02:55.830
effect on regular matter and current


00:02:55.840 --> 00:02:57.790
estimates suggest Dark Matter makes up


00:02:57.800 --> 00:03:00.110
to 85% of all the matter in the the


00:03:00.120 --> 00:03:02.830
universe cold Dark Matter the prevailing


00:03:02.840 --> 00:03:04.789
Dark Matter Theory assumes that dark


00:03:04.799 --> 00:03:07.430
matter particles are collisionless self


00:03:07.440 --> 00:03:09.550
interacting Dark Matter a theoretical


00:03:09.560 --> 00:03:11.670
form of Dark Matter proposes that dark


00:03:11.680 --> 00:03:13.550
matter particles self- interact through


00:03:13.560 --> 00:03:16.750
a new dark force in their study you and


00:03:16.760 --> 00:03:18.509
colleagues used nbody numerical


00:03:18.519 --> 00:03:20.670
simulations to model the behavior of a


00:03:20.680 --> 00:03:23.270
collapsing self indirecting dark mattera


00:03:23.280 --> 00:03:25.589
subhalo their findings therefore offer a


00:03:25.599 --> 00:03:27.589
new explanation for The observed spur


00:03:27.599 --> 00:03:29.830
and GAP features in the gd1 Stream which


00:03:29.840 --> 00:03:31.509
have long been thought to indicate a


00:03:31.519 --> 00:03:33.589
close encounter with some sort of dense


00:03:33.599 --> 00:03:36.509
object you says in this new scenario the


00:03:36.519 --> 00:03:38.710
perturba is a self interacting dark


00:03:38.720 --> 00:03:41.190
matter subhalo which is disrupting the


00:03:41.200 --> 00:03:43.190
spatial and velocity distributions of


00:03:43.200 --> 00:03:45.190
the stars in the Stream and creates the


00:03:45.200 --> 00:03:47.750
distinctive features seen in the Stream


00:03:47.760 --> 00:03:49.710
now if correct the discovery also


00:03:49.720 --> 00:03:51.869
provides new insights into the very


00:03:51.879 --> 00:03:54.190
nature of this mysterious substance


00:03:54.200 --> 00:03:57.990
called Dark Matter this is spacetime


00:03:58.000 --> 00:04:00.110
still to come the sun emits three


00:04:00.120 --> 00:04:02.589
powerful solar flares all on the one day


00:04:02.599 --> 00:04:04.750
and we're in for a spectacular quadrants


00:04:04.760 --> 00:04:07.069
meteor shower all that and more still to


00:04:07.079 --> 00:04:10.680
come on


00:04:10.690 --> 00:04:23.629
[Music]


00:04:23.639 --> 00:04:26.510
SpaceTime our local star the sun has


00:04:26.520 --> 00:04:28.510
shown its violent streak again


00:04:28.520 --> 00:04:30.710
unleashing three significant x-class


00:04:30.720 --> 00:04:33.629
solar flares all on the same day the


00:04:33.639 --> 00:04:35.670
flares were categorized based on their


00:04:35.680 --> 00:04:37.469
intensity with a first and third


00:04:37.479 --> 00:04:39.990
classified as x1.1 flares while the


00:04:40.000 --> 00:04:42.189
second was a more powerful


00:04:42.199 --> 00:04:44.749
x1.5 x-class flares represent the


00:04:44.759 --> 00:04:46.909
highest intensity on the solar flare


00:04:46.919 --> 00:04:49.430
scale with a logarithmic numeric value


00:04:49.440 --> 00:04:51.310
further detailing their specific


00:04:51.320 --> 00:04:53.710
strength the three flares were detected


00:04:53.720 --> 00:04:56.189
by the solar ultraviolet imager operated


00:04:56.199 --> 00:04:58.150
by Noah the national oceanographic and


00:04:58.160 --> 00:05:00.189
Atmospheric Administration America's


00:05:00.199 --> 00:05:02.870
weather bureau solar flares are powerful


00:05:02.880 --> 00:05:05.070
eruptions of energy blasted out by the


00:05:05.080 --> 00:05:07.430
sun they're triggered by snapping


00:05:07.440 --> 00:05:09.790
magnetic field lines emanating from sun


00:05:09.800 --> 00:05:12.430
spots on the solar surface because the


00:05:12.440 --> 00:05:14.790
sun's not a solid body but a fluid


00:05:14.800 --> 00:05:17.230
different latitudes of the Sun rotate at


00:05:17.240 --> 00:05:19.749
different rates and consequently


00:05:19.759 --> 00:05:21.870
magnetic field lines emanating from deep


00:05:21.880 --> 00:05:23.710
inside the Sun and traveling out through


00:05:23.720 --> 00:05:25.110
the sun's visible surface the


00:05:25.120 --> 00:05:27.110
Photosphere are twisted by this


00:05:27.120 --> 00:05:29.790
differential rotation eventually the


00:05:29.800 --> 00:05:31.790
twisting causes them to snap and when


00:05:31.800 --> 00:05:34.950
they snap they release a solar flare now


00:05:34.960 --> 00:05:37.070
if the solar flare is pointed towards


00:05:37.080 --> 00:05:39.510
the Earth it can't cause a lot of damage


00:05:39.520 --> 00:05:41.390
it can even destroy satellites and other


00:05:41.400 --> 00:05:43.469
spacecraft it can also shorten the life


00:05:43.479 --> 00:05:45.790
of orbiting spacecraft by causing Earth


00:05:45.800 --> 00:05:48.309
atmosphere to expand that increases


00:05:48.319 --> 00:05:50.150
atmospheric drag and consequently


00:05:50.160 --> 00:05:52.430
orbital Decay forcing a spacecraft to


00:05:52.440 --> 00:05:54.749
use more fuel in order to maintain its


00:05:54.759 --> 00:05:57.270
operational orbit it can disrupt radio


00:05:57.280 --> 00:05:59.629
communications and navigation systems in


00:05:59.639 --> 00:06:01.670
impact power grids on the ground causing


00:06:01.680 --> 00:06:03.749
blackouts and they can increase an


00:06:03.759 --> 00:06:06.110
astronaut's radiation exposure posing a


00:06:06.120 --> 00:06:08.309
serious health hazard in fact even


00:06:08.319 --> 00:06:10.589
Pilots crew and passengers in highflying


00:06:10.599 --> 00:06:12.629
aircraft can get increased radiation


00:06:12.639 --> 00:06:14.670
exposure when one of these space weather


00:06:14.680 --> 00:06:17.790
events occurs this increase in solar


00:06:17.800 --> 00:06:19.469
activity is all part of the sun's


00:06:19.479 --> 00:06:21.950
buildup to solar maximum the peak of its


00:06:21.960 --> 00:06:24.510
current 11year solar cycle which began


00:06:24.520 --> 00:06:26.029
back in November


00:06:26.039 --> 00:06:29.589
2019 once the Sun reaches solar Max the


00:06:29.599 --> 00:06:32.110
Crescendo of its violent outbursts it'll


00:06:32.120 --> 00:06:34.309
gradually start to come down again until


00:06:34.319 --> 00:06:36.589
it reaches solar minimum at which point


00:06:36.599 --> 00:06:38.749
the sun's polarity will flip its North


00:06:38.759 --> 00:06:40.990
Pole will become South and South Pole


00:06:41.000 --> 00:06:43.990
north this happens roughly every 11


00:06:44.000 --> 00:06:46.469
years although the exact timing is still


00:06:46.479 --> 00:06:50.350
not fully understood this is spacetime


00:06:50.360 --> 00:06:52.350
still to come the quadrants meteor


00:06:52.360 --> 00:06:54.390
shower spectacular and later in the


00:06:54.400 --> 00:06:56.990
science report a new study warns that a


00:06:57.000 --> 00:06:58.749
quarter of the world's freshwater


00:06:58.759 --> 00:07:01.430
animals are now at risk of Extinction


00:07:01.440 --> 00:07:07.700
all that and more still to come on


00:07:07.710 --> 00:07:18.990
[Music]


00:07:19.000 --> 00:07:20.950
SpaceTime the Earth is currently


00:07:20.960 --> 00:07:22.909
experiencing one of its most spectacular


00:07:22.919 --> 00:07:25.230
meteor showers the quadrantids which is


00:07:25.240 --> 00:07:27.270
lighting up the night sky with an array


00:07:27.280 --> 00:07:30.189
of dazzling so-called shooting stars


00:07:30.199 --> 00:07:32.550
shooting stars more accurately meteors


00:07:32.560 --> 00:07:34.629
are made up of dust and debris streams


00:07:34.639 --> 00:07:36.710
left behind by passing comets and


00:07:36.720 --> 00:07:38.710
occasionally by asteroids when the


00:07:38.720 --> 00:07:40.710
Earth's orbit around the sun happens to


00:07:40.720 --> 00:07:42.629
cross one of these streams bits of dust


00:07:42.639 --> 00:07:44.390
and debris end up falling into the


00:07:44.400 --> 00:07:46.309
Earth's atmosphere causing them to heat


00:07:46.319 --> 00:07:47.990
up due to friction with the air and


00:07:48.000 --> 00:07:50.110
eventually burn up usually at altitudes


00:07:50.120 --> 00:07:52.869
of around 80 km and sometimes this can


00:07:52.879 --> 00:07:55.390
produce spectacular light shows the


00:07:55.400 --> 00:07:57.589
quadrantids themselves are generated by


00:07:57.599 --> 00:08:00.869
debris from the near Earth asteroid 1962


00:08:00.879 --> 00:08:05.110
56 2003 eh1 which may actually be an


00:08:05.120 --> 00:08:07.469
extinct Comet first noted by Chinese


00:08:07.479 --> 00:08:10.070
astronomers in 1490 they called the


00:08:10.080 --> 00:08:11.589
quadrantids because they appear to


00:08:11.599 --> 00:08:13.550
originate from a point of the sky called


00:08:13.560 --> 00:08:15.670
a radiant named after the defun


00:08:15.680 --> 00:08:18.029
constellation quadran Morales which is


00:08:18.039 --> 00:08:19.869
now part of the constellation booties


00:08:19.879 --> 00:08:22.869
near the famous plow asterism observers


00:08:22.879 --> 00:08:24.990
enjoying Dark Skies should see around 50


00:08:25.000 --> 00:08:27.390
or more Metals an hour as the quadrants


00:08:27.400 --> 00:08:29.869
reach their Peak the rural Astron iCal


00:08:29.879 --> 00:08:32.149
society's deputy director Robert Massie


00:08:32.159 --> 00:08:33.949
says Sky Watchers on the west coast of


00:08:33.959 --> 00:08:35.670
the United States or in the Pacific


00:08:35.680 --> 00:08:38.110
could see as many 70 or 80 meteors an


00:08:38.120 --> 00:08:40.389
hour including some Fireballs well the


00:08:40.399 --> 00:08:43.110
quadrantic meteor shower is an annual


00:08:43.120 --> 00:08:45.670
shower of meteors and meteors are


00:08:45.680 --> 00:08:48.070
basically the result of small pieces of


00:08:48.080 --> 00:08:49.910
Dey coming into the Earth's atmosphere


00:08:49.920 --> 00:08:52.310
at high speed and but by small I mean


00:08:52.320 --> 00:08:54.509
anything grains of sand up to Marble


00:08:54.519 --> 00:08:56.509
size not very big at all but they come


00:08:56.519 --> 00:09:00.269
in so fast up to 70 km each second many


00:09:00.279 --> 00:09:01.949
times the speed of the bullet that they


00:09:01.959 --> 00:09:04.710
heat the atmosphere around them and that


00:09:04.720 --> 00:09:07.870
hot air glows and that's what we see as


00:09:07.880 --> 00:09:09.949
shooting star or meteor and typically


00:09:09.959 --> 00:09:11.670
they only ask a fraction of a second if


00:09:11.680 --> 00:09:13.190
you're very lucky you might see them


00:09:13.200 --> 00:09:15.230
lasting longer than that but you know


00:09:15.240 --> 00:09:17.190
normally they're very very fleeting


00:09:17.200 --> 00:09:19.269
showers happen because the Earth runs


00:09:19.279 --> 00:09:21.509
into a stream of debris rather than just


00:09:21.519 --> 00:09:23.269
random bits that are coming in all over


00:09:23.279 --> 00:09:24.829
the sky and that's what the quadrantid


00:09:24.839 --> 00:09:26.389
is it's a shower that happens more or


00:09:26.399 --> 00:09:28.430
less at the same time every year It's


00:09:28.440 --> 00:09:30.310
associated with the particular part in


00:09:30.320 --> 00:09:31.949
the sky and that's because the Earth is


00:09:31.959 --> 00:09:34.670
running into a particular stream of Dey


00:09:34.680 --> 00:09:37.069
now the name comes from the fact that


00:09:37.079 --> 00:09:40.069
it's associated with the now defunct


00:09:40.079 --> 00:09:42.470
constellation quadron Morales which


00:09:42.480 --> 00:09:43.870
basically means a quadrant that was


00:09:43.880 --> 00:09:45.590
mounted on a wall and this was a


00:09:45.600 --> 00:09:47.350
constellation that was created as many


00:09:47.360 --> 00:09:49.829
were in the 17th and 18th centuries but


00:09:49.839 --> 00:09:51.670
it wasn't adopted in the present day


00:09:51.680 --> 00:09:53.550
it's actually in the part of the sky


00:09:53.560 --> 00:09:55.670
between Ursa Major which includes the


00:09:55.680 --> 00:09:57.389
plow if you're familiar with that in the


00:09:57.399 --> 00:09:59.910
UK and the constellation of both B the


00:09:59.920 --> 00:10:01.550
herdsman so it's in that region of the


00:10:01.560 --> 00:10:03.350
sky not far from the poar the


00:10:03.360 --> 00:10:05.350
quadrantids are unusual and that they


00:10:05.360 --> 00:10:07.630
appear to be Associated uh not


00:10:07.640 --> 00:10:09.670
necessarily with a Comal maybe an


00:10:09.680 --> 00:10:12.710
extinct one but with a an asteroid


00:10:12.720 --> 00:10:15.590
called 2003 eh1 which means it was


00:10:15.600 --> 00:10:17.509
discovered in 2003 now it passes


00:10:17.519 --> 00:10:19.389
reasonably near the Earth it's called a


00:10:19.399 --> 00:10:21.509
near Earth object and we appear to be


00:10:21.519 --> 00:10:23.710
running into a trail of Deb associated


00:10:23.720 --> 00:10:25.829
with it so the thinking is that might


00:10:25.839 --> 00:10:27.910
actually be an extinct com so no longer


00:10:27.920 --> 00:10:30.069
anything generating a tail doesn't look


00:10:30.079 --> 00:10:31.710
like a comet these days just looks like


00:10:31.720 --> 00:10:33.949
a DOT on even images on the LA from the


00:10:33.959 --> 00:10:34.829
largest


00:10:34.839 --> 00:10:38.829
telescopes but 500 years ago there was a


00:10:38.839 --> 00:10:41.670
com seen back in 1490 more than 500


00:10:41.680 --> 00:10:43.430
years ago there was a comment seen by


00:10:43.440 --> 00:10:46.910
the Chinese and it may be connected with


00:10:46.920 --> 00:10:48.710
that so it may be that this Comet was


00:10:48.720 --> 00:10:51.150
once active there left a lot of Dey in


00:10:51.160 --> 00:10:52.829
an orbit around the C system which the


00:10:52.839 --> 00:10:55.230
Earth runs into once a year and that


00:10:55.240 --> 00:10:57.710
leads to the quadrantid meteos well the


00:10:57.720 --> 00:10:59.870
quadrantids are not bad as meteor


00:10:59.880 --> 00:11:03.550
showers go they have a pretty strong


00:11:03.560 --> 00:11:05.190
intensity if you happen to be in the


00:11:05.200 --> 00:11:06.750
right place at the right time so if you


00:11:06.760 --> 00:11:08.430
are on the you know the west coast of


00:11:08.440 --> 00:11:10.230
the US and the Pacific region you could


00:11:10.240 --> 00:11:13.190
see maybe 70 or 80 an hour if you're in


00:11:13.200 --> 00:11:14.750
the UK you're going to see somewhat


00:11:14.760 --> 00:11:16.870
fewer than that or is it's likely that's


00:11:16.880 --> 00:11:19.670
the case but but but it's still a strong


00:11:19.680 --> 00:11:21.870
shower the great Advantage this year is


00:11:21.880 --> 00:11:23.590
that the moon isn't interfering with it


00:11:23.600 --> 00:11:24.670
so you haven't got a full moon in the


00:11:24.680 --> 00:11:26.389
sky it's a very thin cresant that means


00:11:26.399 --> 00:11:27.750
the light from the moon will not be a


00:11:27.760 --> 00:11:29.829
big problem and if you get out of the


00:11:29.839 --> 00:11:32.030
city into a dark place away from sources


00:11:32.040 --> 00:11:34.190
of light pollution then you have a


00:11:34.200 --> 00:11:36.110
chance maybe of seeing a few up to a few


00:11:36.120 --> 00:11:37.389
tens of meteors an hour maybe


00:11:37.399 --> 00:11:39.269
realistically perhaps 20 to


00:11:39.279 --> 00:11:41.949
25 they won't be the brightest meteors


00:11:41.959 --> 00:11:44.230
on the whole but they it does include a


00:11:44.240 --> 00:11:45.990
fair number of fireable is quite


00:11:46.000 --> 00:11:47.629
typically a fireable is dramatic


00:11:47.639 --> 00:11:49.150
sounding thing what it really means is a


00:11:49.160 --> 00:11:51.110
really bright meteor and the quadrantids


00:11:51.120 --> 00:11:52.829
is a meteor shower that produces that


00:11:52.839 --> 00:11:55.030
kind of event so for that reason alone


00:11:55.040 --> 00:11:56.550
if you have the time to look out and the


00:11:56.560 --> 00:11:58.829
weather is good then do take a look the


00:11:58.839 --> 00:12:01.110
really nice thing about a meteor shower


00:12:01.120 --> 00:12:02.590
is that you don't need any special


00:12:02.600 --> 00:12:04.030
equipment you just basically need to


00:12:04.040 --> 00:12:06.949
have half decent eyesight uh if you have


00:12:06.959 --> 00:12:08.710
a telescope or binocular you try to


00:12:08.720 --> 00:12:09.910
watch a meteor show you're going to make


00:12:09.920 --> 00:12:11.230
it harder because you'll only be seeing


00:12:11.240 --> 00:12:13.389
a tiny part of the sky what you need to


00:12:13.399 --> 00:12:16.430
do is go out be prepared to wait outside


00:12:16.440 --> 00:12:18.350
for a bit and just watch the sky they


00:12:18.360 --> 00:12:20.230
could be anywhere in the sky so the the


00:12:20.240 --> 00:12:21.790
biggest piece of the best piece of


00:12:21.800 --> 00:12:23.829
advice rather that I would give is just


00:12:23.839 --> 00:12:26.030
to look up look at the sky get an


00:12:26.040 --> 00:12:27.910
uncluttered view be away from the lights


00:12:27.920 --> 00:12:30.230
of towns and cities and see what you see


00:12:30.240 --> 00:12:32.310
but do be patient don't go outside and


00:12:32.320 --> 00:12:33.550
if you don't see one in the first five


00:12:33.560 --> 00:12:35.350
minutes be disappointed I think the


00:12:35.360 --> 00:12:36.870
thing to do is to give it maybe half an


00:12:36.880 --> 00:12:38.230
hour or something you i' be very


00:12:38.240 --> 00:12:39.750
surprised if you didn't see any in that


00:12:39.760 --> 00:12:42.470
time photographing meteor showers uh


00:12:42.480 --> 00:12:45.350
requires patience if you take your say


00:12:45.360 --> 00:12:46.949
your mobile phone camera up and you just


00:12:46.959 --> 00:12:48.670
click at the sky you're unlikely to


00:12:48.680 --> 00:12:49.829
capture anything because they're so


00:12:49.839 --> 00:12:51.189
fleeing they only last perhaps a


00:12:51.199 --> 00:12:53.269
fraction of a second your reactions are


00:12:53.279 --> 00:12:54.150
not going to be good enough to


00:12:54.160 --> 00:12:56.230
photograph it so what people tend to do


00:12:56.240 --> 00:12:57.550
that are used to photographing is they


00:12:57.560 --> 00:12:59.790
do what I called long exposure so they


00:12:59.800 --> 00:13:02.990
open up the the lens the the shutter or


00:13:03.000 --> 00:13:04.670
the the electronic shutter depending on


00:13:04.680 --> 00:13:06.069
how you define it to say something like


00:13:06.079 --> 00:13:08.990
a phone and leave it running actually


00:13:09.000 --> 00:13:10.949
for as long at least in total as a


00:13:10.959 --> 00:13:13.069
period of minutes anything up to half an


00:13:13.079 --> 00:13:15.310
hour in some cases people have all Sky


00:13:15.320 --> 00:13:17.470
cameras that run all night and you have


00:13:17.480 --> 00:13:18.990
to do that because you never know


00:13:19.000 --> 00:13:21.670
exactly when the m is coming and so you


00:13:21.680 --> 00:13:23.389
need a long period of time to see them


00:13:23.399 --> 00:13:25.870
if you do it well and I guess people


00:13:25.880 --> 00:13:28.829
with dslrs that can run for hours or


00:13:28.839 --> 00:13:30.269
anything the best place to do this


00:13:30.279 --> 00:13:31.790
that's another option just a more


00:13:31.800 --> 00:13:33.949
sophisticated digital camera what you'll


00:13:33.959 --> 00:13:36.590
see is star Trails these are the result


00:13:36.600 --> 00:13:38.269
of the Earth turning and then the stars


00:13:38.279 --> 00:13:41.110
appear to Trail across the sky as they


00:13:41.120 --> 00:13:42.590
they appear to move and then


00:13:42.600 --> 00:13:44.670
superimposed on that we'll see streaks


00:13:44.680 --> 00:13:46.750
of light bright streaks and those are


00:13:46.760 --> 00:13:49.030
the meteors those will be the quadrantic


00:13:49.040 --> 00:13:51.230
so it's not as simple as say holding up


00:13:51.240 --> 00:13:52.470
your camera and taking a picture of the


00:13:52.480 --> 00:13:54.829
Northern Lights uh my advice would be to


00:13:54.839 --> 00:13:56.509
read up on it beforehand don't try and


00:13:56.519 --> 00:13:58.230
do it on the night because I think it'll


00:13:58.240 --> 00:14:00.030
be a struggle but if you've got the


00:14:00.040 --> 00:14:02.110
right kind of setup a decent tripod an


00:14:02.120 --> 00:14:04.629
ability to open up your camera for a


00:14:04.639 --> 00:14:06.389
long period of time then you should see


00:14:06.399 --> 00:14:08.310
something that's the deputy director of


00:14:08.320 --> 00:14:10.949
the Royal Astronomical Society Dr Robert


00:14:10.959 --> 00:14:13.990
Massie and this is spacetime


00:14:14.000 --> 00:14:29.990
[Music]


00:14:30.000 --> 00:14:31.590
and time now to take another brief look


00:14:31.600 --> 00:14:33.110
at some of the other stories making news


00:14:33.120 --> 00:14:35.389
and science this week with a science


00:14:35.399 --> 00:14:38.150
report a new study warns that a quarter


00:14:38.160 --> 00:14:40.030
of the world's freshwater animals are


00:14:40.040 --> 00:14:42.710
now at risk of Extinction the findings


00:14:42.720 --> 00:14:44.590
reported in the journal Nature based on


00:14:44.600 --> 00:14:47.110
a study of more than 23,000 fish


00:14:47.120 --> 00:14:49.910
crustations and insects scientists


00:14:49.920 --> 00:14:52.150
classify the species Extinction risks


00:14:52.160 --> 00:14:55.310
finding 24% were vulnerable or Worse


00:14:55.320 --> 00:14:57.030
similar to the proportion of high-risk


00:14:57.040 --> 00:14:59.590
freshwater mammals birds amphibians and


00:14:59.600 --> 00:15:01.710
reptiles however the two groups have


00:15:01.720 --> 00:15:03.550
different habitats and face different


00:15:03.560 --> 00:15:05.710
threats with those in this study most


00:15:05.720 --> 00:15:08.150
threatened by pollution dams water


00:15:08.160 --> 00:15:10.990
extraction land use change and invasive


00:15:11.000 --> 00:15:13.189
species the authors stress that the


00:15:13.199 --> 00:15:15.110
needs of this group of animals should


00:15:15.120 --> 00:15:17.350
also be considered when it comes to any


00:15:17.360 --> 00:15:19.710
forms of freshwater


00:15:19.720 --> 00:15:22.509
management a new study has confirmed


00:15:22.519 --> 00:15:24.749
that eating a diet of plant-based Foods


00:15:24.759 --> 00:15:26.949
could help increase your microbiome that


00:15:26.959 --> 00:15:29.509
favors human health a report in the


00:15:29.519 --> 00:15:31.749
journal Nature microbiology looked into


00:15:31.759 --> 00:15:33.269
the diets of over


00:15:33.279 --> 00:15:35.949
21,500 people and investigated what


00:15:35.959 --> 00:15:37.910
microbiomes were present depending on


00:15:37.920 --> 00:15:40.749
their food intake a microbiome simply


00:15:40.759 --> 00:15:42.949
refers to the gut microbes in your


00:15:42.959 --> 00:15:45.230
intestines the authors then compared the


00:15:45.240 --> 00:15:47.590
diets of omnivores against vegetarians


00:15:47.600 --> 00:15:50.389
and against vegans they suggested those


00:15:50.399 --> 00:15:52.030
who ate high amounts of healthy


00:15:52.040 --> 00:15:54.069
plant-based and fiber rich foods had


00:15:54.079 --> 00:15:56.389
larger colonies of good microbes those


00:15:56.399 --> 00:15:58.189
related to Good Health compared to their


00:15:58.199 --> 00:16:00.309
peers


00:16:00.319 --> 00:16:02.110
a new study has shown that all that


00:16:02.120 --> 00:16:04.350
scrolling and posting you're doing might


00:16:04.360 --> 00:16:06.189
well end up causing you to become far


00:16:06.199 --> 00:16:08.629
more irritable a report in the Journal


00:16:08.639 --> 00:16:10.509
of the American Medical Association


00:16:10.519 --> 00:16:12.910
surveyed over 40,000 people about their


00:16:12.920 --> 00:16:15.110
social media habits and the potential


00:16:15.120 --> 00:16:17.629
effect it has on their emotions they


00:16:17.639 --> 00:16:19.470
found that people who frequently use


00:16:19.480 --> 00:16:21.509
social media especially those who post


00:16:21.519 --> 00:16:23.430
it frequently scored significantly


00:16:23.440 --> 00:16:25.749
higher on an arability test compared to


00:16:25.759 --> 00:16:28.110
the social media free or infrequent use


00:16:28.120 --> 00:16:30.870
of peers now this kind of static can't


00:16:30.880 --> 00:16:32.990
prove that your hours of Doom scrolling


00:16:33.000 --> 00:16:35.269
are directly making you ticked off but


00:16:35.279 --> 00:16:37.110
in the light of known associations of


00:16:37.120 --> 00:16:39.189
irritability and mental health issues


00:16:39.199 --> 00:16:41.389
maybe you should put down your phones


00:16:41.399 --> 00:16:42.829
just a little


00:16:42.839 --> 00:16:45.189
more well there's been massive news and


00:16:45.199 --> 00:16:47.189
Technology this week with Facebook boss


00:16:47.199 --> 00:16:49.110
Mark zugerberg admitting what we've been


00:16:49.120 --> 00:16:51.189
telling you for years fact Checkers


00:16:51.199 --> 00:16:53.269
can't be trusted with the truth they're


00:16:53.279 --> 00:16:55.150
dishonest and they lie to push a


00:16:55.160 --> 00:16:57.790
political agenda from the corrupt and


00:16:57.800 --> 00:16:59.870
scientifically stupid fact Checkers of


00:16:59.880 --> 00:17:01.949
YouTube through to the Socialist fact


00:17:01.959 --> 00:17:04.630
Checkers of the rmit fact lab never


00:17:04.640 --> 00:17:06.949
trust what they say always do your own


00:17:06.959 --> 00:17:09.270
research and always go to the original


00:17:09.280 --> 00:17:11.990
Source The Babylon B probably put it


00:17:12.000 --> 00:17:13.789
best when they wrote that the guy who


00:17:13.799 --> 00:17:15.750
said Facebook was not suppressing Free


00:17:15.760 --> 00:17:17.750
Speech has now announced that Facebook


00:17:17.760 --> 00:17:20.270
will stop suppressing free speech with


00:17:20.280 --> 00:17:22.110
the details we're joined by technology


00:17:22.120 --> 00:17:24.750
editor Alex saharov Roy from Tech advice


00:17:24.760 --> 00:17:26.909
start life it was very surprising to see


00:17:26.919 --> 00:17:28.909
Mark Zuckerberg with extremely curly ha


00:17:28.919 --> 00:17:31.270
coming out and saying on video that he


00:17:31.280 --> 00:17:32.390
was getting rid of fact Checkers


00:17:32.400 --> 00:17:34.669
Zuckerberg's admitted that his fact


00:17:34.679 --> 00:17:36.150
Checkers are phony and he was going to


00:17:36.160 --> 00:17:38.270
implement Community notes in a system


00:17:38.280 --> 00:17:40.350
that's similar to X which does appear to


00:17:40.360 --> 00:17:42.150
be the fairest system the whole idea is


00:17:42.160 --> 00:17:43.909
is that people are checking up on other


00:17:43.919 --> 00:17:45.390
people and you're not relying upon the


00:17:45.400 --> 00:17:47.190
single source of Truth be the government


00:17:47.200 --> 00:17:49.669
or rmit university you know socialist


00:17:49.679 --> 00:17:51.510
scumbag fact Checkers who are trying to


00:17:51.520 --> 00:17:54.230
shut down all sorts of views that don't


00:17:54.240 --> 00:17:55.870
align with their views and Mark


00:17:55.880 --> 00:17:57.549
Zuckerberg is doing this because he's


00:17:57.559 --> 00:17:59.830
trying to save his political skin well


00:17:59.840 --> 00:18:02.029
of course admitted that he was taking


00:18:02.039 --> 00:18:03.669
instructions from the White House well


00:18:03.679 --> 00:18:05.270
in one sense he would have probably not


00:18:05.280 --> 00:18:06.510
had much Choice he would have become a


00:18:06.520 --> 00:18:07.909
bit of an enemy himself but the thing is


00:18:07.919 --> 00:18:09.590
Mark Zuckerberg did not appear to fight


00:18:09.600 --> 00:18:11.070
back and given the fact he's had a


00:18:11.080 --> 00:18:13.909
20year apology tour I don't trust Mark


00:18:13.919 --> 00:18:15.990
Zuckerberg and him to come out it's uh


00:18:16.000 --> 00:18:17.390
great to see that he's finally done it


00:18:17.400 --> 00:18:19.310
but it's probably about 20 years too


00:18:19.320 --> 00:18:20.590
late and of course when it comes to


00:18:20.600 --> 00:18:23.230
trust Apple have had to do a bigab about


00:18:23.240 --> 00:18:26.669
face $95 million in payouts after it was


00:18:26.679 --> 00:18:29.270
found that Siri really was listening in


00:18:29.280 --> 00:18:31.230
yes now the the problem here is that


00:18:31.240 --> 00:18:33.230
whether it's Google whether it's Amazon


00:18:33.240 --> 00:18:35.710
Alexa or Siri if you say Hey Siri or


00:18:35.720 --> 00:18:37.990
Siri or the Wake word then the system is


00:18:38.000 --> 00:18:39.549
listening and the problem is that when


00:18:39.559 --> 00:18:41.909
the system thinks it has heard the word


00:18:41.919 --> 00:18:43.710
Siri because you said sorry or because


00:18:43.720 --> 00:18:45.510
you said some other word that sounded


00:18:45.520 --> 00:18:47.990
like that it starts listening and starts


00:18:48.000 --> 00:18:50.070
recording now terrible if you run an


00:18:50.080 --> 00:18:52.830
Indian clothing store well what about


00:18:52.840 --> 00:18:54.510
Tom Cruz's daughter sui oh and I've


00:18:54.520 --> 00:18:56.070
heard the same sort of story for young


00:18:56.080 --> 00:18:57.230
people called you know young girls


00:18:57.240 --> 00:18:58.870
called alexe in school their friends


00:18:58.880 --> 00:19:00.470
like Alex so do this and do that and


00:19:00.480 --> 00:19:01.830
haha it's very funny but clearly the


00:19:01.840 --> 00:19:03.390
joke does wear off after a while but the


00:19:03.400 --> 00:19:05.669
short version is that because these


00:19:05.679 --> 00:19:08.870
interactions normally not direct where


00:19:08.880 --> 00:19:10.750
you're giving the assistant an


00:19:10.760 --> 00:19:12.390
instruction what was happening is that


00:19:12.400 --> 00:19:14.110
the system would listen and it would


00:19:14.120 --> 00:19:16.669
then send these conversations off to


00:19:16.679 --> 00:19:18.549
humans to listen and try and figure out


00:19:18.559 --> 00:19:20.070
and try and train the system to do


00:19:20.080 --> 00:19:21.710
better now sometimes people were being


00:19:21.720 --> 00:19:24.190
recorded making love or having arguments


00:19:24.200 --> 00:19:26.470
or getting beaten up even murders and


00:19:26.480 --> 00:19:28.350
private business information was being


00:19:28.360 --> 00:19:29.950
unveil and that's why some people refuse


00:19:29.960 --> 00:19:32.029
to have any smart speakers in their


00:19:32.039 --> 00:19:34.870
homes yeah well it is also possible to


00:19:34.880 --> 00:19:37.789
have Siri only be activated by pushing


00:19:37.799 --> 00:19:39.470
the button on the side of your phone I


00:19:39.480 --> 00:19:40.990
use Siri a lot I use it to set


00:19:41.000 --> 00:19:42.669
appointments and make calls and set


00:19:42.679 --> 00:19:44.350
timers and remind me to do things and


00:19:44.360 --> 00:19:46.549
take notes so it does have its uses and


00:19:46.559 --> 00:19:48.630
you can tell your systems now they


00:19:48.640 --> 00:19:49.950
brought this in over the past couple of


00:19:49.960 --> 00:19:52.149
years to not send your recordings not


00:19:52.159 --> 00:19:54.789
share your recordings with Apple so I


00:19:54.799 --> 00:19:56.830
never want my recordings to be shared or


00:19:56.840 --> 00:19:58.470
any of the diagnostic information or


00:19:58.480 --> 00:19:59.950
always turn that off because I'm worried


00:19:59.960 --> 00:20:02.430
about it too anyway this lawsuit saw


00:20:02.440 --> 00:20:04.669
Apple not admitting any liability and


00:20:04.679 --> 00:20:06.470
it's hard to know how they're going to


00:20:06.480 --> 00:20:07.950
avoid this in the future I do know that


00:20:07.960 --> 00:20:09.950
if I say hey Siri or Siri that another


00:20:09.960 --> 00:20:12.029
iPhone I have lights up for a second but


00:20:12.039 --> 00:20:13.710
it instantly it turns off because it


00:20:13.720 --> 00:20:15.510
knows that I haven't given it a command


00:20:15.520 --> 00:20:16.990
and it was just sort of an accidental


00:20:17.000 --> 00:20:18.630
wake word so this is a problem where we


00:20:18.640 --> 00:20:20.310
need to trust the companies to do what


00:20:20.320 --> 00:20:21.430
they say they're going to do and if not


00:20:21.440 --> 00:20:22.390
they'll get caught out by some


00:20:22.400 --> 00:20:24.310
enterprising hacker and find hundreds of


00:20:24.320 --> 00:20:25.750
millions of dollars trusting companies


00:20:25.760 --> 00:20:27.630
is like trusting governments mate they


00:20:27.640 --> 00:20:30.710
famous last words CES is wrapped up in


00:20:30.720 --> 00:20:33.549
Las Vegas once again lots of gadgets how


00:20:33.559 --> 00:20:35.510
many of them do we really need is the


00:20:35.520 --> 00:20:37.149
big question but there' have been some


00:20:37.159 --> 00:20:39.430
fantastic products as well such as what


00:20:39.440 --> 00:20:41.470
Nidia are doing yeah they've launched a


00:20:41.480 --> 00:20:43.590
whole series of updates to their AI


00:20:43.600 --> 00:20:45.190
chips the ones that we use when we talk


00:20:45.200 --> 00:20:48.190
to chat GPT but also launched a $33,000


00:20:48.200 --> 00:20:50.149
supercomputer that you can hold in your


00:20:50.159 --> 00:20:52.149
hand a bit like an Apple Mac Mini that's


00:20:52.159 --> 00:20:55.430
meant to have 1,000 times the power of


00:20:55.440 --> 00:20:57.669
your existing laptop computer and


00:20:57.679 --> 00:20:58.830
although you know most people people are


00:20:58.840 --> 00:21:00.950
not using a computer powered by an


00:21:00.960 --> 00:21:03.430
Nvidia chip to do their Computing many


00:21:03.440 --> 00:21:05.149
people do have an Nvidia graphics card


00:21:05.159 --> 00:21:06.630
and and some of the graphics card


00:21:06.640 --> 00:21:08.470
capabilities I mean we will soon have


00:21:08.480 --> 00:21:10.950
movies that look photorealistically


00:21:10.960 --> 00:21:13.669
human but are completely designed on a


00:21:13.679 --> 00:21:15.190
computer and it's going to put certain


00:21:15.200 --> 00:21:16.909
actors and actresses out of work if you


00:21:16.919 --> 00:21:18.110
don't have to have humans and it can all


00:21:18.120 --> 00:21:19.510
be done by a computer why not but that's


00:21:19.520 --> 00:21:21.870
just one of the many things there BMW


00:21:21.880 --> 00:21:23.830
who launched their iDrive 24 years ago


00:21:23.840 --> 00:21:25.789
there's a little system and a screen now


00:21:25.799 --> 00:21:28.630
the entire windscreen windshield can be


00:21:28.640 --> 00:21:30.990
a display one giant heads up display


00:21:31.000 --> 00:21:32.710
just like a fire that's right and


00:21:32.720 --> 00:21:34.390
that'll keep they said your eyes on the


00:21:34.400 --> 00:21:35.710
road and your hands on the wheel there


00:21:35.720 --> 00:21:38.630
was a concept of a uh system that like a


00:21:38.640 --> 00:21:40.310
mirror that you stood on it could weigh


00:21:40.320 --> 00:21:43.029
you could look at your weight your your


00:21:43.039 --> 00:21:44.710
height your heart your metabolic health


00:21:44.720 --> 00:21:47.310
I mean like a giant Tri quar Robo Rock


00:21:47.320 --> 00:21:49.190
one of the vacuum cleaner makers where


00:21:49.200 --> 00:21:50.630
the vacuum cleaners Scurry around your


00:21:50.640 --> 00:21:52.430
house finds a teddy bear or something in


00:21:52.440 --> 00:21:54.029
the way normally it stops or it has to


00:21:54.039 --> 00:21:55.789
go around it in with this particular


00:21:55.799 --> 00:21:58.070
robot an arm pops out of the top of the


00:21:58.080 --> 00:22:00.590
unit and it can physically lift items


00:22:00.600 --> 00:22:03.269
out of the way like yeah Ros of the


00:22:03.279 --> 00:22:05.110
robot and like Jensen hang did at one of


00:22:05.120 --> 00:22:06.390
his previous Keynotes where he had a


00:22:06.400 --> 00:22:08.149
whole stack of robots behind him that


00:22:08.159 --> 00:22:09.789
just rose out of the stage when he did


00:22:09.799 --> 00:22:12.110
it again at CES he had all these robots


00:22:12.120 --> 00:22:14.310
that just popped out from behind him and


00:22:14.320 --> 00:22:15.950
these robots are incredibly Advanced


00:22:15.960 --> 00:22:17.149
there was even a robot that's sort of


00:22:17.159 --> 00:22:18.710
the size of a child that was filmed


00:22:18.720 --> 00:22:20.789
wandering around CES walking quite


00:22:20.799 --> 00:22:23.590
naturally so the age of the robots truly


00:22:23.600 --> 00:22:26.350
is upon us and the trick will be to get


00:22:26.360 --> 00:22:28.630
them to the price of smartphones you


00:22:28.640 --> 00:22:30.230
know if you can afford to buy a robot


00:22:30.240 --> 00:22:32.630
that can mine the kids wash the dishes


00:22:32.640 --> 00:22:33.909
do various things around the home for


00:22:33.919 --> 00:22:35.470
you and it's B the cost of a mobile


00:22:35.480 --> 00:22:37.269
phone who wouldn't get one Elon Musk


00:22:37.279 --> 00:22:40.070
sees a market for billions of them at


00:22:40.080 --> 00:22:41.669
least one for every human in the future


00:22:41.679 --> 00:22:43.430
there are plenty of cing smart glasses


00:22:43.440 --> 00:22:46.390
that can have a little 3.5 in monochrome


00:22:46.400 --> 00:22:48.510
display that you're looking at but that


00:22:48.520 --> 00:22:50.029
can also have an AI agent that's


00:22:50.039 --> 00:22:51.909
listening to conversations answering


00:22:51.919 --> 00:22:53.549
