00:00:00 --> 00:00:02 Stuart Gary: This is Space Time Series 28, episode
00:00:02 --> 00:00:05 109 for broadcast on 10 September
00:00:05 --> 00:00:08 2025. Coming up on Space Time,
00:00:08 --> 00:00:11 solar flares over six times hotter than
00:00:11 --> 00:00:13 previously thought. Understanding how the
00:00:13 --> 00:00:16 planet Jupiter's core was formed. And
00:00:16 --> 00:00:19 could life be evolving right now on our, uh,
00:00:19 --> 00:00:22 nearest exoplanetary neighbours? All that
00:00:22 --> 00:00:24 and more coming up on Space Time.
00:00:26 --> 00:00:28 Voice Over Guy: Welcome to Space Time with Stuart
00:00:28 --> 00:00:29 Gary
00:00:45 --> 00:00:48 Stuart Gary: A new study has shown, uh, that massive explosions of
00:00:48 --> 00:00:51 energy blasting off the sun, known as solar flares,
00:00:51 --> 00:00:53 can reach temperatures of over 60 million degrees,
00:00:54 --> 00:00:56 some six and a half times hotter than previously thought.
00:00:57 --> 00:01:00 The findings reported in the Astrophysical Journal Letters
00:01:00 --> 00:01:03 may provide an unexpected solution to a 50 year
00:01:03 --> 00:01:06 old mystery about our nearest star. These
00:01:06 --> 00:01:09 dramatic events greatly increase the levels of
00:01:09 --> 00:01:11 solar X rays and radiation reaching the Earth and they're
00:01:11 --> 00:01:14 hazardous to spacecraft and astronauts as well as
00:01:14 --> 00:01:17 affecting our planet's upper atmosphere. Solar
00:01:17 --> 00:01:20 flares heat parts of the sun's outer atmosphere, the corona,
00:01:20 --> 00:01:22 to temperatures of more than 10 million degrees.
00:01:23 --> 00:01:26 That compares to the sun's surface temperature of 6
00:01:26 --> 00:01:29 degrees and uh, its core temperature of about 15 million
00:01:29 --> 00:01:32 degrees. The new research examined evidence of how
00:01:32 --> 00:01:34 flares heat solar plasma, which is made up of ions and
00:01:34 --> 00:01:37 electrons. The study's authors argue that
00:01:37 --> 00:01:40 solar flare ions, positively charged particles that make
00:01:40 --> 00:01:43 up half of the plasma, can reach temperatures of more than 60
00:01:43 --> 00:01:45 million degrees. The study's lead author,
00:01:45 --> 00:01:48 Alexander Russell from the University of St. Andrews, says
00:01:48 --> 00:01:51 solar flares very likely heat the ions more
00:01:51 --> 00:01:54 strongly than they do electrons. Russell says
00:01:54 --> 00:01:57 recent discoveries show that a process called magnetic
00:01:57 --> 00:01:59 reconnection heats ions 6.5 times
00:01:59 --> 00:02:02 as much as they do electrons. And this appears to be a
00:02:02 --> 00:02:05 universal law confirmed in near Earth, uh, space, the
00:02:05 --> 00:02:08 solar wind and in computer simulations.
00:02:08 --> 00:02:11 However, Russell points out that no one had previously connected
00:02:11 --> 00:02:13 work in those fields to solar flares.
00:02:14 --> 00:02:17 He says solar physics had historically always assumed that
00:02:17 --> 00:02:19 ions and electrons must have the same temperature.
00:02:20 --> 00:02:23 However, redoing the calculations using modern data,
00:02:23 --> 00:02:25 Russell found that ion and electron temperature differences can
00:02:25 --> 00:02:28 last for as long as 10 minutes in important parts of
00:02:28 --> 00:02:31 solar flares, opening the way to consider super hot
00:02:31 --> 00:02:34 ions for the first time. And the new
00:02:34 --> 00:02:36 ion temperature data fits in well with
00:02:36 --> 00:02:39 observations of the width of solar flare spectral
00:02:39 --> 00:02:42 lines, potentially solving an astrophysics mystery that
00:02:42 --> 00:02:45 stood for nearly half a century. See, there's been
00:02:45 --> 00:02:47 a long standing question ever since the 1970s
00:02:47 --> 00:02:50 about why flare spectral lines, bright enhancements
00:02:50 --> 00:02:53 of the solar radio radiation at specific colours in extreme
00:02:53 --> 00:02:56 ultraviolet and X ray light, are uh, broader than they should
00:02:56 --> 00:02:58 be. And historically this was believed to be
00:02:58 --> 00:03:01 caused by turbulent motions. But that
00:03:01 --> 00:03:04 interpretation came under pressure as scientists tried to
00:03:04 --> 00:03:07 identify the nature of the turbulence. That's where the
00:03:07 --> 00:03:10 new work comes in. After nearly 50 years,
00:03:10 --> 00:03:13 it argues for a paradigm shift where the ion
00:03:13 --> 00:03:15 temperature can make a large contribution to explaining the
00:03:15 --> 00:03:18 enigmatic line width of solar flare spectra.
00:03:19 --> 00:03:21 This is space time still to come.
00:03:22 --> 00:03:25 Understanding how the gas giant Jupiter formed its
00:03:25 --> 00:03:27 core. And could life be evolving right now
00:03:27 --> 00:03:30 on our nearest exoplanetary neighbours? All that
00:03:30 --> 00:03:33 and more still to come on space time.
00:03:45 --> 00:03:45 Alex Zaharov-Reutt: Foreign.
00:03:49 --> 00:03:52 Stuart Gary: The long standing mystery of how Jupiter's core was
00:03:52 --> 00:03:55 formed has just been given a new twist, with fresh computer
00:03:55 --> 00:03:58 simulations suggesting a giant impact couldn't have
00:03:58 --> 00:04:01 created what astronomers are seeing. A
00:04:01 --> 00:04:03 report in the Journal of the Monthly Notices of the Royal
00:04:03 --> 00:04:06 Astronomical Society suggests a giant impact may not
00:04:06 --> 00:04:09 have been responsible for the formation of the Jovian core.
00:04:09 --> 00:04:12 After all, it had been thought that a colossal
00:04:12 --> 00:04:14 collision with an early planet containing half of
00:04:14 --> 00:04:17 Jupiter's core material could have mixed up the central region of
00:04:17 --> 00:04:20 the gas giant enough to explain the interior we
00:04:20 --> 00:04:23 see today. But the new modelling suggests
00:04:23 --> 00:04:26 its makeup's actually down to how the growing planet
00:04:26 --> 00:04:29 absorbed heavy and light materials as it formed
00:04:29 --> 00:04:32 and evolved. Unlike what scientists once expected,
00:04:32 --> 00:04:34 the core of the largest planet in our solar system
00:04:34 --> 00:04:37 doesn't have a sharp boundary. Instead,
00:04:37 --> 00:04:40 it simply gradually blends into the surrounding
00:04:40 --> 00:04:43 layer of mostly hydrogen, forming a structure known
00:04:43 --> 00:04:46 as a dilute core. Now, how this dilute
00:04:46 --> 00:04:49 core formed has been a key question among astronomers ever
00:04:49 --> 00:04:51 since NASA's Juno spacecraft first revealed its
00:04:51 --> 00:04:54 existence. Before Juno, scientists
00:04:54 --> 00:04:57 speculated that Jupiter's core would simply be pure
00:04:57 --> 00:04:59 metallic hydrogen. But Juno's readings
00:04:59 --> 00:05:02 changed all that. Jupiter is the fifth
00:05:02 --> 00:05:05 planet from the Sun. It is nearly two and a half times
00:05:05 --> 00:05:08 the mass of all the other planets in the solar system combined.
00:05:08 --> 00:05:11 Its diameter is some 11 times that of the Earth,
00:05:11 --> 00:05:13 and it's a full 10th the diameter of the Sun.
00:05:14 --> 00:05:16 Jupiter orbits the sun at an average distance of
00:05:16 --> 00:05:19 779 million kilometres, with an orbital
00:05:19 --> 00:05:22 period of 11.86 Earth years.
00:05:23 --> 00:05:26 Using new supercomputer simulations of planetary
00:05:26 --> 00:05:28 impacts, the authors tested whether a massive collision
00:05:28 --> 00:05:31 could have created Jupiter's dilute core.
00:05:32 --> 00:05:35 But the study found that a stable dilute core structure was
00:05:35 --> 00:05:37 not produced by any of the simulations conducted, even
00:05:37 --> 00:05:40 those involving impacts under really extreme conditions.
00:05:41 --> 00:05:43 Instead, the simulations demonstrated that the
00:05:43 --> 00:05:46 dense rock and ice core material displaced by an
00:05:46 --> 00:05:49 impact would quickly resettle, leaving a distinct
00:05:49 --> 00:05:52 boundary within the outer layers of hydrogen and helium,
00:05:52 --> 00:05:55 rather than forming a smooth transition zone between the two
00:05:55 --> 00:05:57 regions. The study's lead author, Thomas
00:05:57 --> 00:06:00 Sanders from Durham University, says it was fascinating to
00:06:00 --> 00:06:03 explore how a gas giant like Jupiter would
00:06:03 --> 00:06:06 respond to one of the most violent events a growing planet could
00:06:06 --> 00:06:09 ever experience. The simulations showed that
00:06:09 --> 00:06:12 this kind of impact quite literally shakes the planet
00:06:12 --> 00:06:15 to its core, just not in the right way to explain
00:06:15 --> 00:06:17 the interior of Jupiter as it's now understood.
00:06:18 --> 00:06:20 We now know Jupiter isn't the only planet with a
00:06:20 --> 00:06:23 dilute core. Astronomers recently found evidence that
00:06:23 --> 00:06:26 Saturn has one too. The fact that Saturn
00:06:26 --> 00:06:29 also has a dilute core strengthens the idea that these
00:06:29 --> 00:06:32 structures are not the results of rare, extremely
00:06:32 --> 00:06:35 high energy impacts, but instead form gradually
00:06:35 --> 00:06:37 during the long process of planetary growth and
00:06:37 --> 00:06:40 evolution. This is space time
00:06:41 --> 00:06:44 still to come. Could life be evolving right now on our
00:06:44 --> 00:06:47 nearest exoplanetary neighbours? And later in the Science
00:06:47 --> 00:06:49 report, the new technology which will increase
00:06:49 --> 00:06:52 Internet speeds by up to 45%.
00:06:52 --> 00:06:55 All that and more still to come on, uh, space time.
00:07:10 --> 00:07:13 Scientists are speculating over the tantalising possibility
00:07:13 --> 00:07:16 that life could be evolving right now on, um, some of
00:07:16 --> 00:07:18 Earth's nearest exoplanetary neighbours.
00:07:19 --> 00:07:22 The prospect of life beyond Earth and whether we're alone
00:07:22 --> 00:07:25 in the universe is one of those ultimate questions
00:07:25 --> 00:07:27 of science. When rocky Earth like planets were
00:07:27 --> 00:07:30 first discovered orbiting in the habitable zones of some of our
00:07:30 --> 00:07:33 nearest stellar neighbours, excitement among scientists
00:07:33 --> 00:07:36 skyrocketed. That was until they realised
00:07:36 --> 00:07:39 that any hopes of life would be dashed by the high levels of
00:07:39 --> 00:07:41 radiation which would be bombarding these worlds.
00:07:42 --> 00:07:44 For example, Proxima Centauri is one of three
00:07:44 --> 00:07:47 planets in the Alpha Centauri star system, which is the nearest
00:07:47 --> 00:07:50 stellar system to the sun. Scientists have
00:07:50 --> 00:07:53 discovered three planets orbiting Proxima Centauri.
00:07:53 --> 00:07:55 One of those, Proxima B, located some
00:07:55 --> 00:07:58 4.24 light years away, is a rocky Earth like
00:07:58 --> 00:08:01 planet located within Proxima Centauri's habitable
00:08:01 --> 00:08:04 zone. That's the distance from a star where it's not
00:08:04 --> 00:08:07 too hot and not too cold, but just right for
00:08:07 --> 00:08:10 liquid water, essential for life as we know it to pool
00:08:10 --> 00:08:13 on a planet's surface. The problem is
00:08:13 --> 00:08:15 Proxima b receives some 250 times more
00:08:15 --> 00:08:18 x ray radiation than the Earth does, and could also be
00:08:18 --> 00:08:21 experiencing deadly levels of ultraviolet radiation on its
00:08:21 --> 00:08:24 surface. So how could life possibly
00:08:24 --> 00:08:26 survive such a bombardment? Well,
00:08:26 --> 00:08:29 astronomers Lisa Kaltenegger and Jack o' Malley James
00:08:29 --> 00:08:32 from Cornell University believe they've got proof that
00:08:32 --> 00:08:35 life has already survived this kind of fierce radiation
00:08:35 --> 00:08:38 right here on Earth. Their work, which was reported
00:08:38 --> 00:08:41 in the monthly notices of the Royal Astronomical Society, shows
00:08:41 --> 00:08:44 how life on Earth today evolved from creatures that
00:08:44 --> 00:08:46 actually thrived during an even greater ultraviolet
00:08:46 --> 00:08:49 radiation assault than what Proxima B and other nearby
00:08:49 --> 00:08:52 exoplanets are currently enduring. You see,
00:08:52 --> 00:08:54 the Earth of 4 billion years ago was a
00:08:54 --> 00:08:56 chaotic, irradiated hot mess.
00:08:57 --> 00:09:00 Yet in spite of this, somehow life gained
00:09:00 --> 00:09:03 a foothold and then expanded. Carlton Egger and
00:09:03 --> 00:09:06 o' Malley James say the same thing could be happening right now on
00:09:06 --> 00:09:09 some of our nearest exoplanetary neighbours.
00:09:09 --> 00:09:12 To reach their conclusions, the authors model the surface
00:09:12 --> 00:09:15 ultraviolet environments of the four exoplanets closest
00:09:15 --> 00:09:17 to Earth, uh, that are potentially habitable. Proxima M
00:09:17 --> 00:09:20 B, Trappist1E, Ross128B
00:09:20 --> 00:09:23 and LHS1140B.
00:09:23 --> 00:09:26 Now, all these planets orbit small spectral type M
00:09:26 --> 00:09:29 red dwarf stars. Unlike, um, our sun,
00:09:29 --> 00:09:32 Red dwarfs flare frequently, bathing any
00:09:32 --> 00:09:34 orbiting planets in high energy ultraviolet
00:09:34 --> 00:09:37 radiation. Now, uh, while it's, uh, unknown exactly what
00:09:37 --> 00:09:40 conditions prevail on the surface of the planets orbiting these flaring
00:09:40 --> 00:09:43 stars, it is known that such flares are both biologically
00:09:43 --> 00:09:45 damaging and they cause the erosion of a planetary
00:09:45 --> 00:09:48 atmosphere. High levels of radiation cause
00:09:48 --> 00:09:51 biological molecules like nucleic acids to mutate and
00:09:51 --> 00:09:54 even shut down. So o' ah, Malley James and
00:09:54 --> 00:09:57 Kaltenaga modelled various atmospheric compositions
00:09:57 --> 00:10:00 from ones very similar to present day Earth to eroded and
00:10:00 --> 00:10:03 anoxic atmospheres. Those with very thin atmospheres
00:10:03 --> 00:10:06 that don't block ultraviolet radiation well, and those
00:10:06 --> 00:10:09 without the protection of ozone. The models show
00:10:09 --> 00:10:11 that as atmospheres thin and ozone levels decrease,
00:10:11 --> 00:10:14 more high energy ultraviolet radiation reaches the ground.
00:10:15 --> 00:10:18 The authors then compared their models to early Earth's history
00:10:18 --> 00:10:20 from nearly 4 billion years ago through to today.
00:10:21 --> 00:10:24 Although the model planets all receive higher ultraviolet
00:10:24 --> 00:10:27 radiation doses than what's emitted by our sun today,
00:10:27 --> 00:10:30 it's still significantly less than what Earth received
00:10:30 --> 00:10:33 3.9 billion years ago. Kaltenega
00:10:33 --> 00:10:35 says given that the early Earth was inhabited, the research
00:10:35 --> 00:10:38 shows that ultraviolet radiation should not be a
00:10:38 --> 00:10:41 limiting factor for habitability of planets orbiting
00:10:41 --> 00:10:44 spectral type M stars. She says some of
00:10:44 --> 00:10:47 Earth's nearest neighbouring exoplanetary worlds remain
00:10:47 --> 00:10:50 intriguing targets in the search for life beyond
00:10:50 --> 00:10:51 our solar system.
00:10:51 --> 00:10:54 Jonathan Nally: My name is Lisa Kaltenegger. I am the director of the Carl Sagan
00:10:54 --> 00:10:56 Institute here at Cornell, developing the
00:10:56 --> 00:10:59 forensic toolkit to find life in the
00:10:59 --> 00:11:02 universe, inside our solar system and
00:11:02 --> 00:11:04 outside. We live in this
00:11:04 --> 00:11:07 amazing time where we found thousands
00:11:07 --> 00:11:10 of other planets, planets that don't orbit our own
00:11:10 --> 00:11:13 sun, but other suns, other stars that you
00:11:13 --> 00:11:16 can see in the night sky. And the
00:11:16 --> 00:11:19 next one over after our sun is
00:11:19 --> 00:11:21 actually a small red star called Proxima
00:11:21 --> 00:11:24 Centauri. And even the next star
00:11:24 --> 00:11:27 in only four light years away, has a
00:11:27 --> 00:11:30 planet that could potentially be like an Earth at
00:11:30 --> 00:11:32 the right distance. So it's not too hot and not too
00:11:32 --> 00:11:35 cold for there to be liquid surface
00:11:35 --> 00:11:38 water. So the big question that
00:11:38 --> 00:11:41 arose when looking at this young red
00:11:41 --> 00:11:44 sun is whether the harsh UV radiation
00:11:44 --> 00:11:47 that it flings out at its planet would
00:11:47 --> 00:11:49 actually be detrimental to life
00:11:50 --> 00:11:53 starting to evolve there. And what we figured
00:11:53 --> 00:11:55 out is when we calculated how much of this
00:11:55 --> 00:11:58 harsh UV radiation would make it to the
00:11:58 --> 00:12:01 ground on that planet, is that
00:12:01 --> 00:12:04 it would be worse than currently on Earth.
00:12:04 --> 00:12:07 So for you and me, it wouldn't be the best place to be.
00:12:07 --> 00:12:10 But it's less than it was on a
00:12:10 --> 00:12:13 young Earth. And on a young Earth,
00:12:13 --> 00:12:16 we had life. So the chances
00:12:17 --> 00:12:19 to finding life close to us
00:12:20 --> 00:12:23 around the closest stars that happen to be
00:12:23 --> 00:12:26 red young suns is much
00:12:26 --> 00:12:29 greater now. And so our quests
00:12:29 --> 00:12:32 to figure out whether we alone in the universe just
00:12:32 --> 00:12:34 got a tiny bit easier.
00:12:34 --> 00:12:36 Stuart Gary: That's Lisa Kaltenaga from Cornell University.
00:12:37 --> 00:12:39 And, um, this is space, time
00:12:55 --> 00:12:57 and time. Now to take another brief look at some of the other stories making
00:12:57 --> 00:13:00 news in Science this week with a Science report.
00:13:00 --> 00:13:03 A new genetic study has shown that the first
00:13:03 --> 00:13:05 Australians arrived Down under sometime around
00:13:05 --> 00:13:08 50 years ago. The new findings,
00:13:08 --> 00:13:11 reported in the journal Archaeology in Oceania, analysed
00:13:11 --> 00:13:14 traces of Neanderthal DNA in Homo sapiens.
00:13:14 --> 00:13:17 The results are based on previous studies showing that Homo
00:13:17 --> 00:13:20 sapiens and Neanderthals interbred, uh, over a period of
00:13:20 --> 00:13:22 several thousand years between
00:13:22 --> 00:13:23 43
00:13:24 --> 00:13:26 1 years ago.
00:13:27 --> 00:13:30 So most modern non African humans, um, and that includes
00:13:30 --> 00:13:32 Indigenous Australians, carry between 1 and 4%
00:13:32 --> 00:13:35 Neanderthal DNA. The new findings are also
00:13:35 --> 00:13:38 in general agreement with the latest archaeological data from across
00:13:38 --> 00:13:41 Australia, which points to the first appearance of first
00:13:41 --> 00:13:44 nations in Australia in a range somewhere between
00:13:44 --> 00:13:47 43 and 54 years ago.
00:13:47 --> 00:13:50 Overall, the findings contradict previous estimates
00:13:50 --> 00:13:53 which suggested the arrival of the first Aboriginal Australians on
00:13:53 --> 00:13:56 what we call terra australis was 65
00:13:56 --> 00:13:58 years ago as a group known as the Sabul
00:13:58 --> 00:14:01 peoples. The seasonal
00:14:01 --> 00:14:04 outlook from the National Council for Foreign Emergency Services
00:14:04 --> 00:14:07 is warning that southwestern Victoria and patches of
00:14:07 --> 00:14:10 northern Western Australia are, uh, likely to face a heightened
00:14:10 --> 00:14:13 risk of bushfires or wildfires during this coming
00:14:13 --> 00:14:16 spring. The agency says the spring outlook
00:14:16 --> 00:14:19 has identified the Dampier Peninsula, the Derby coast and
00:14:19 --> 00:14:22 central Kimberley, the Little Sandy Desert and the south eastern
00:14:22 --> 00:14:24 Pilbara region of Western Australia as areas of
00:14:24 --> 00:14:27 concern over the next few months. They also
00:14:27 --> 00:14:30 conclude that the southeastern agricultural regions of the
00:14:30 --> 00:14:33 Murraylands in South Australia and The South, South
00:14:33 --> 00:14:35 West Central and parts of the Gippsland region of
00:14:35 --> 00:14:38 Victoria should also be at heightened alert during
00:14:38 --> 00:14:41 spring. New research has
00:14:41 --> 00:14:44 shown that transmitting the light through a hollow core optical
00:14:44 --> 00:14:47 fibre can actually speed up data transmission by as much
00:14:47 --> 00:14:50 as 45%. The findings, reported
00:14:50 --> 00:14:53 in the journal Nature Photonics, also show that hollow
00:14:53 --> 00:14:56 core fibre will allow data to travel further without the
00:14:56 --> 00:14:59 need of a boost. Regular fibre optic
00:14:59 --> 00:15:01 cables, such as the ones that might be connecting your home to
00:15:01 --> 00:15:04 the Internet, rely on data being transmitted through a thin
00:15:04 --> 00:15:07 glass tube. The authors found that because their
00:15:07 --> 00:15:10 new design guides light through the hollow core of the fibre,
00:15:10 --> 00:15:13 it's travelling through air rather than being impeded by
00:15:13 --> 00:15:16 the glass. Also, current optical fibre
00:15:16 --> 00:15:19 cables lose about half of the light sent through them by the time
00:15:19 --> 00:15:22 they reach about 20 kilometres from the point of origin.
00:15:22 --> 00:15:25 Because of this, they need amplifiers to boost the signal at, uh,
00:15:25 --> 00:15:28 regular intervals. The authors say their new holo
00:15:28 --> 00:15:31 fibres would let data travel 50% further
00:15:31 --> 00:15:34 before needing a boost. And that could open the door to much more
00:15:34 --> 00:15:36 data being transmitted without distortion.
00:15:37 --> 00:15:40 Samsung have used Europe's biggest tech show to launch their
00:15:40 --> 00:15:43 latest products. With the details, we're joined by
00:15:43 --> 00:15:46 technology editor Alex Harovroid from Tech Advice.
00:15:46 --> 00:15:47 Start live.
00:15:47 --> 00:15:50 Alex Zaharov-Reutt: There's a big conference in Germany called ifa. This is
00:15:50 --> 00:15:53 the European equivalent of the CES show in
00:15:53 --> 00:15:56 Las Vegas or the COMPI Tech show in Taiwan. And there's been lots
00:15:56 --> 00:15:58 of technological announcements. Samsung made a number of
00:15:58 --> 00:16:01 announcements. One was to launch the new Fan
00:16:01 --> 00:16:04 edition of its S25 range. This normally
00:16:04 --> 00:16:06 comes at this time of the year. It's the cheaper
00:16:07 --> 00:16:10 version of the flagship S25 series and
00:16:10 --> 00:16:13 comes a few months before Samsung launches its S26.
00:16:13 --> 00:16:16 Effectively, it has all the latest technologies, but at a cheaper
00:16:16 --> 00:16:19 price. And it behoves interested parties to
00:16:19 --> 00:16:21 see if the actual S25 range itself
00:16:21 --> 00:16:24 has received any discounts on sales. Because if you
00:16:24 --> 00:16:27 can get the full S25 or the plus or the Ultra at
00:16:27 --> 00:16:30 a cheaper rate than you could when it launched in January, that would be better
00:16:30 --> 00:16:33 than the cheaper Fan edition. So that's one of the things
00:16:33 --> 00:16:35 that people look out for this time of the year.
00:16:35 --> 00:16:38 Also, Samsung has the new S11, which is their
00:16:38 --> 00:16:40 tablet range. They have one in 14.6
00:16:40 --> 00:16:43 inches and one in 11 inches. Last year they had one in the 12
00:16:43 --> 00:16:46 inch size as well. They don't seem to have launched that mid
00:16:46 --> 00:16:49 size model this year. These are of course very thin.
00:16:49 --> 00:16:52 They compete with the iPad that is, uh, five
00:16:52 --> 00:16:55 millimetres thick. So Samsung of course has similar ambitions
00:16:55 --> 00:16:58 to be very sleek and thick. But the other
00:16:58 --> 00:17:00 big thing that Samsung launched was a new
00:17:00 --> 00:17:03 micro RGB television technology
00:17:03 --> 00:17:06 which is in 115 inches. So
00:17:06 --> 00:17:09 it's a giant size, something that's in between the
00:17:09 --> 00:17:12 QLED Nano displays and the OLED display.
00:17:12 --> 00:17:15 So this is a third technology. It's just going to mean
00:17:15 --> 00:17:18 there's more choice in the stores, more reason for you to
00:17:18 --> 00:17:21 want to spend thousands on a TV when some of the supermarkets sell
00:17:21 --> 00:17:24 80 inch TVs for under $1. And it's just the
00:17:24 --> 00:17:27 incessant progress and march of tech with AI and
00:17:27 --> 00:17:29 new technologies being the reasons why
00:17:29 --> 00:17:31 suddenly you have to spend more money.
