In this episode of SpaceTime, we uncover remarkable revelations about Jupiter, lightning-induced gamma rays, and groundbreaking achievements in spaceflight.
Jupiter's Magnificent Past
A new study reveals that Jupiter, the solar system's largest planet, was once twice its current size and possessed a magnetic field 50 times stronger than today. Researchers, led by Konstantin Batygin, used the orbits of Jupiter's small moons, Amalthea and Thebe, to deduce these findings, providing critical insights into the early stages of planetary formation. The implications of this research could reshape our understanding of gas giants and their formation processes across the universe.
Gamma Rays and Lightning
In a groundbreaking discovery, scientists have detected intense flashes of gamma rays produced by lightning strikes. This phenomenon, known as terrestrial gamma ray flashes, occurs when lightning accelerates electrons to near light speeds, resulting in bursts of radiation. The study, published in Science Advances, sheds light on the high-energy processes occurring in Earth's atmosphere, enhancing our understanding of lightning's power and its effects on our planet.
Precision Formation Flying in Space
History has been made in Earth orbit as two spacecraft from the European Space Agency's Proba 3 mission successfully flew in millimeter-perfect formation for the first time. This precision alignment is crucial for studying the Sun's corona, allowing the two satellites to simulate a single large spacecraft. We discuss the technology behind this mission and its potential to revolutionize solar observations.

00:00:00 --> 00:00:03 Stuart Gary: This is space Time Series 28, episode

00:00:03 --> 00:00:06 64 for broadcast on 28 May

00:00:06 --> 00:00:08 2025. Coming up on Space Time,

00:00:09 --> 00:00:12 a new study shows that Jupiter was once twice as

00:00:12 --> 00:00:15 big as it is now. How gamma ray flashes

00:00:15 --> 00:00:18 are, unleashed by lightning and spaceflight

00:00:18 --> 00:00:21 history made as two spacecraft orbiting the Earth

00:00:21 --> 00:00:23 fly in millimeter perfect formation.

00:00:24 --> 00:00:27 All that and more coming up on Space Time.

00:00:28 --> 00:00:31 Voice Over Guy: Welcome to Space Time with Stuart Gary

00:00:31 --> 00:00:31 Gary.

00:00:47 --> 00:00:50 Stuart Gary: A new study has found that the solar system's largest

00:00:50 --> 00:00:53 planet, Jupiter, was once twice as big as it is now

00:00:53 --> 00:00:55 and had a far stronger magnetic field.

00:00:56 --> 00:00:59 Jupiter is the fifth planet from the sun, and the

00:00:59 --> 00:01:02 gas giant has more than 2.5 times the combined mass

00:01:02 --> 00:01:05 of all the other bodies in the solar system, excluding

00:01:05 --> 00:01:07 the sun. Its diameter of 140

00:01:08 --> 00:01:10 km is some 11 times larger

00:01:10 --> 00:01:13 than that of Earth, and It's a full 1/10 the size of

00:01:13 --> 00:01:16 the Sun's diameter. Jupiter is huge.

00:01:17 --> 00:01:19 That's why it's often referred to as the King of Planets.

00:01:20 --> 00:01:22 It circles the sun at an average distance some

00:01:22 --> 00:01:25 5.2 times further out than the Earth, taking

00:01:25 --> 00:01:27 11.86 Earth years to complete each orbit.

00:01:28 --> 00:01:31 The new findings, reported in the journal Nature Astronomy,

00:01:31 --> 00:01:34 suggest that around 3.8 million years after

00:01:34 --> 00:01:37 the solar system's formation, 4.6 billion years

00:01:37 --> 00:01:40 ago, at a time when the first solids condensed out of

00:01:40 --> 00:01:42 the Sun's protoplanetary disk, Jupiter, was

00:01:42 --> 00:01:45 significantly larger and had an even more powerful

00:01:45 --> 00:01:48 magnetic field. One of the study's authors,

00:01:48 --> 00:01:51 Konstantin Batygin, says the ultimate goal of the research

00:01:51 --> 00:01:54 has been to pin down the early phase of planetary

00:01:54 --> 00:01:57 formation. Batygin and colleagues reached their findings

00:01:57 --> 00:02:00 by studying Jupiter's tiny moons, Amalthea and

00:02:00 --> 00:02:02 Thebe. They orbit even closer to Jupiter than

00:02:02 --> 00:02:05 IO, the smallest and nearest of the planet's four large

00:02:05 --> 00:02:08 Galilean moons. because Amalthea and

00:02:08 --> 00:02:11 Thebe have slightly tilted orbits, the authors were able to

00:02:11 --> 00:02:14 analyze these small orbital discrepancies in order to calculate

00:02:14 --> 00:02:17 Jupiter's original size, finding it to be about

00:02:17 --> 00:02:20 twice that of its current radius, with a predicted volume that

00:02:20 --> 00:02:22 was equivalent to over 2000 times that of

00:02:22 --> 00:02:25 Earth. They also calculated that the planet's

00:02:25 --> 00:02:28 magnetic field was some 50 times stronger than

00:02:28 --> 00:02:31 what it is today. This new analysis is

00:02:31 --> 00:02:33 establishing a clear snapshot of Jupiter at the moment

00:02:33 --> 00:02:36 its surrounding solar nebula evaporated. And

00:02:36 --> 00:02:39 that's a pivotal transition point where the building materials of

00:02:39 --> 00:02:42 planet formation disappear and the primordial

00:02:42 --> 00:02:45 architecture of our solar system was finally locked in.

00:02:45 --> 00:02:48 The results add crucial details to existing

00:02:48 --> 00:02:51 planet formation theories, suggesting that Jupiter, as

00:02:51 --> 00:02:54 well as other Gas giants around other stars were all

00:02:54 --> 00:02:57 formed through a process of core accretion in which

00:02:57 --> 00:02:59 rocky and icy cores are first established and

00:02:59 --> 00:03:01 then rapidly gather surrounding gas.

00:03:02 --> 00:03:05 This space time still to come.

00:03:05 --> 00:03:08 A new study describes how gamma ray flashes in

00:03:08 --> 00:03:11 Earth's atmosphere are unleashed by lightning

00:03:11 --> 00:03:14 and spaceflight. History has been made in Earth orbit with

00:03:14 --> 00:03:16 two spacecraft successfully flying in millimeter perfect

00:03:16 --> 00:03:19 formation for several hours for the first time. All

00:03:19 --> 00:03:21 that and more still to come. on space time

00:03:37 --> 00:03:40 scientists have detected intense flashes of high energy gamma

00:03:40 --> 00:03:43 rays associated with the collision of two bolts of

00:03:43 --> 00:03:45 lightning. Lightning is a phenomenon that's

00:03:45 --> 00:03:48 fascinated humanity since time immemorial,

00:03:48 --> 00:03:50 providing a stark example of the power and

00:03:50 --> 00:03:53 unpredictability of the natural world world.

00:03:53 --> 00:03:56 Although the study of lightning can be challenging, scientists

00:03:56 --> 00:03:59 have in recent years made great strides in developing

00:03:59 --> 00:04:01 their understanding of this extreme spectacle.

00:04:02 --> 00:04:05 Now a report in the journal Science Advances has

00:04:05 --> 00:04:07 described for the first time observations of an

00:04:07 --> 00:04:10 intense burst of radiation known as terrestrial gamma ray

00:04:10 --> 00:04:13 flash synchronized with a lightning discharge.

00:04:13 --> 00:04:16 The study's lead author Yuki Wada from the University of

00:04:16 --> 00:04:19 Osaka says the ability to study extreme

00:04:19 --> 00:04:22 processes such as terrestrial gamma ray flashes originating

00:04:22 --> 00:04:24 from lightning allows scientists better better understand

00:04:24 --> 00:04:27 the high energy processes occurring in Earth's atmosphere.

00:04:28 --> 00:04:30 It has been hypothesized that terrestrial gamma ray

00:04:30 --> 00:04:33 flashes arise from lightning discharges as a result of

00:04:33 --> 00:04:36 the acceleration of electrons to very high speeds.

00:04:37 --> 00:04:39 However, the transient nature of this phenomenon, which only

00:04:39 --> 00:04:42 lasts for microseconds, has always made it difficult to

00:04:42 --> 00:04:45 study the hypothesis. So Weider and

00:04:45 --> 00:04:48 colleagues developed a multi sensor setup designed

00:04:48 --> 00:04:50 specifically to detect optical radio frequency and

00:04:50 --> 00:04:53 high energy radiation events. They were able

00:04:53 --> 00:04:56 to observe two discharge paths of lightning, one

00:04:56 --> 00:04:59 descending from the thundercloud to the ground based transmission

00:04:59 --> 00:05:02 tower and one ascending up in the opposite direction.

00:05:03 --> 00:05:05 Weider and colleagues found that terrestrial gamma ray flashes

00:05:05 --> 00:05:08 occurred just before the two discharge paths met, creating

00:05:08 --> 00:05:11 a highly concentrated electric field that accelerated

00:05:11 --> 00:05:14 electrons in the air to near the speed of light.

00:05:14 --> 00:05:17 The first terrestrial gamma ray flash photon was observed

00:05:17 --> 00:05:20 31 microseconds before the collision of the

00:05:20 --> 00:05:22 discharge paths and the full burst lasted for

00:05:22 --> 00:05:25 20 microseconds after they emit to form the lightning

00:05:25 --> 00:05:28 strike. The study contributes crucial data

00:05:28 --> 00:05:30 to the long standing mystery of how lightning

00:05:30 --> 00:05:33 generates enough energy to produce gamma rays, a

00:05:33 --> 00:05:36 phenomenon normally associated with outer space events

00:05:36 --> 00:05:38 like supernovae or black holes.

00:05:39 --> 00:05:41 The study also supports emerging theories about

00:05:41 --> 00:05:44 lightning leader dynamics and ah, the potential role of

00:05:44 --> 00:05:47 thermal runaway or relativistic feedback in these

00:05:47 --> 00:05:50 extreme bursts. This is space

00:05:50 --> 00:05:53 time still to come. Spaceflight history

00:05:53 --> 00:05:56 made in Earth orbit with two spacecraft successfully flying in

00:05:56 --> 00:05:59 millimeter perfect formation for several hours for the first

00:05:59 --> 00:06:01 time. And later in the science report,

00:06:01 --> 00:06:04 researchers develop a new type of contact lens. One that

00:06:04 --> 00:06:07 will help you see in the dark. All that and more still

00:06:07 --> 00:06:09 to come on, Space Time.

00:08:18 --> 00:08:19 And now it's back to our show.

00:08:26 --> 00:08:29 Spaceflight history has been made in Earth. orbit. With two

00:08:29 --> 00:08:32 spacecraft successfully flying in millimeter perfect formation

00:08:32 --> 00:08:35 for several hours. For the first time and without

00:08:35 --> 00:08:38 any control from the ground, the European Space

00:08:38 --> 00:08:40 agency's Probe 3 mission achieved a precision alignment

00:08:40 --> 00:08:43 which is needed in order to carry out its mission to study the

00:08:43 --> 00:08:46 Sun's outer atmosphere, the corona. You see, the

00:08:46 --> 00:08:49 two Proba 3 spacecraft, which include a Coronagraph

00:08:49 --> 00:08:52 orbiter and an Occulta orbiter, need to fly

00:08:52 --> 00:08:54 exactly 150 meters apart in perfect

00:08:54 --> 00:08:57 formation in order to simulate a single giant

00:08:57 --> 00:09:00 spacecraft. Earlier this year, the first step of

00:09:00 --> 00:09:03 the mission was successfully completed. Using a

00:09:03 --> 00:09:06 set of positioning instruments, flight operations managers were able

00:09:06 --> 00:09:09 to align the two spacecraft in formation and then

00:09:09 --> 00:09:11 monitor them as they maintain their relative position

00:09:11 --> 00:09:14 autonomously. Now, following more fine tuning

00:09:14 --> 00:09:17 and testing, the team have achieved the desired level of

00:09:17 --> 00:09:20 precision they need, making Prober3 the world's

00:09:20 --> 00:09:22 first ever precision formation flying mission.

00:09:23 --> 00:09:25 ESA Probe III systems engineer Rafael Rogo

00:09:26 --> 00:09:28 says the task was carried out at an orbital altitude of

00:09:28 --> 00:09:31 50 km. Here, Earth's

00:09:31 --> 00:09:34 gravitational pull is small enough so that very little propellant

00:09:34 --> 00:09:37 is needed to maintain flight formation. But then

00:09:37 --> 00:09:40 the formation is broken and needs to be acquired again over

00:09:40 --> 00:09:43 the next orbit in a repeating cycle. Now the

00:09:43 --> 00:09:46 ultimate goal is for the two spacecraft to align with the sun

00:09:46 --> 00:09:48 so that the 1.4 meter disk carried on the occulta

00:09:48 --> 00:09:51 spacecraft casts a 5 cm shadow onto the

00:09:51 --> 00:09:54 optical instrument aboard the Coronagraph spacecraft, thereby

00:09:54 --> 00:09:57 allowing it to study the faint solar corona, the

00:09:57 --> 00:10:00 Sun's outer atmosphere. The spacecraft are able to

00:10:00 --> 00:10:03 measure and control their relative position using a visually based

00:10:03 --> 00:10:06 system which includes a wide angle camera on the Occulta

00:10:06 --> 00:10:09 tracking a set of flashing LED lights on the Chronograph

00:10:09 --> 00:10:12 spacecraft. Once the satellites get close enough

00:10:12 --> 00:10:15 to each other, a narrow angle camera locks onto the same

00:10:15 --> 00:10:17 set of lights, enabling more accurate positioning.

00:10:18 --> 00:10:20 Then a fine degree lateral and longitudinal sensor

00:10:20 --> 00:10:23 laser is used to achieve the millimetre accuracy needed

00:10:23 --> 00:10:26 for the mission. That laser is fired from the

00:10:26 --> 00:10:29 Occulta spacecraft and reflected by the chronograph's

00:10:29 --> 00:10:31 retroreflector back to the Occulta where it's detected.

00:10:32 --> 00:10:35 Finally, a shadow position sensor, measures light intensity

00:10:35 --> 00:10:38 around the coronagraph aperture to ensure the spacecraft stays

00:10:38 --> 00:10:40 in the shadow cast by the Occulta spacecraft.

00:10:41 --> 00:10:43 This report from ESAtv

00:10:43 --> 00:10:45 ProBA, from the.

00:10:45 --> 00:10:48 Unidentified (Commentator): Latin for let's try, is

00:10:48 --> 00:10:50 ESA's family of experimental small

00:10:50 --> 00:10:53 satellites. Over the last two

00:10:53 --> 00:10:55 decades, ProBA missions have pushed forward

00:10:55 --> 00:10:58 spaceflight technology while gathering valuable

00:10:58 --> 00:11:01 science data. The next in the series,

00:11:01 --> 00:11:04 Proba 3, is the most ambitious

00:11:04 --> 00:11:07 yet. Two satellites fly together

00:11:07 --> 00:11:10 as one of the with millimeter level control of

00:11:10 --> 00:11:12 their positions within a precise formation.

00:11:13 --> 00:11:15 In the process, one will

00:11:15 --> 00:11:18 eclipse or block the sun for the other.

00:11:19 --> 00:11:22 To reveal our star's faint surrounding coronal

00:11:22 --> 00:11:24 atmosphere for scientific observation,

00:11:25 --> 00:11:27 Probe III requires a unique orbit.

00:11:28 --> 00:11:30 The Occulta Spacecraft, with its 1.4

00:11:30 --> 00:11:33 meter diameter occulting disk, could observe the sun

00:11:33 --> 00:11:34 and eclipse.

00:11:36 --> 00:11:39 The satellite's orbit is highly elliptical,

00:11:39 --> 00:11:42 taking them to a maximum of 60

00:11:42 --> 00:11:43 km from Earth.

00:11:45 --> 00:11:48 Gravitational, magnetic and atmospheric

00:11:48 --> 00:11:51 perturbations are much lower this far out.

00:11:51 --> 00:11:54 This will make possible the precise positioning needed for

00:11:54 --> 00:11:57 formation flying and observing the Sun's

00:11:57 --> 00:12:00 corona. At this stage, it is important that the

00:12:00 --> 00:12:03 Probe III satellites perform a series of maneuvers to

00:12:03 --> 00:12:06 position themselves in relatively safe orbits with

00:12:06 --> 00:12:07 respective to each other.

00:12:09 --> 00:12:12 Achieving this nullifies any risk of the pair

00:12:12 --> 00:12:15 either drifting away from each other or colliding.

00:12:16 --> 00:12:18 The separation between spacecraft will be as short

00:12:18 --> 00:12:21 as 25 meters and as long as

00:12:21 --> 00:12:24 250 meters with a nominal

00:12:24 --> 00:12:27 separation of around 150 meters.

00:12:27 --> 00:12:30 The pair determine their relative positions

00:12:30 --> 00:12:33 using a suite of metrologies and including

00:12:33 --> 00:12:36 radio links, satellite navigation and the

00:12:36 --> 00:12:38 visual based system with optical tracking of

00:12:38 --> 00:12:41 blinking lights. Once

00:12:41 --> 00:12:44 sufficient accuracy has been achieved, the final

00:12:44 --> 00:12:47 step deploy the most precise measuring system of

00:12:47 --> 00:12:50 all, the laser metrology system,

00:12:50 --> 00:12:53 known as the fine lateral and longitudinal

00:12:53 --> 00:12:53 sensor.

00:12:54 --> 00:12:57 Unidentified (Commentator): With this laser link, the total three dimensional

00:12:57 --> 00:13:00 formation can attain millimetre level control.

00:13:02 --> 00:13:05 At this point, the Occulta lined up with the

00:13:05 --> 00:13:08 sun will cast a perfect shadow for sustained

00:13:08 --> 00:13:10 observation of the Sun's otherwise invisible

00:13:10 --> 00:13:13 corona. Once the

00:13:13 --> 00:13:16 Occulta's shadow is maintained in just the right

00:13:16 --> 00:13:18 spot on the face of the other satellite,

00:13:18 --> 00:13:21 it will be safe for the coronagraph to open its

00:13:21 --> 00:13:24 protective door and start scientific observations

00:13:24 --> 00:13:25 of the Sun's corona.

00:13:27 --> 00:13:30 Solar Scientists travel the world to glimpse brief

00:13:30 --> 00:13:33 solar eclipses, but Prober 3

00:13:33 --> 00:13:35 will create eclipses on demand.

00:13:40 --> 00:13:41 Stuart Gary: This is space, time

00:13:57 --> 00:14:00 and time. Now to take another brief look at some of the other stories making

00:14:00 --> 00:14:02 news in Science this week with a Science report.

00:14:03 --> 00:14:06 Scientists have developed a new type of contact lens, one

00:14:06 --> 00:14:09 that will help you see in the dark. A report in the

00:14:09 --> 00:14:11 journal Cell claims the lenses work by converting

00:14:11 --> 00:14:14 infrared light, otherwise imperceptible to the human eye,

00:14:14 --> 00:14:17 into visible light. And unlike night vision

00:14:17 --> 00:14:20 goggles, these lenses don't need an external power source.

00:14:21 --> 00:14:23 The technology behind the lenses rely on

00:14:23 --> 00:14:26 nanoparticles that absorb infrared, which the

00:14:26 --> 00:14:29 authors bonded with non toxic polymers used in standard contact

00:14:29 --> 00:14:31 lenses. When tested on people, participants

00:14:31 --> 00:14:34 could detect the location of flashing infrared lights, which they

00:14:34 --> 00:14:36 wouldn't be able to see without the contacts.

00:14:37 --> 00:14:40 Additionally, the authors say they could alter the nanoparticles to convert

00:14:40 --> 00:14:43 different wavelengths of light into different colors,

00:14:43 --> 00:14:45 thereby allowing colorblind people to see colour.

00:14:46 --> 00:14:49 currently the lenses can only detect infrared light projected from

00:14:49 --> 00:14:52 an LED light source, but researchers are now working on a

00:14:52 --> 00:14:55 version that could detect lower levels of infrared light

00:14:55 --> 00:14:57 out in the wild. It

00:14:57 --> 00:15:00 turns out the humpback whale's epic migrations to

00:15:00 --> 00:15:03 tropical waters from the Great Southern Ocean are ah, not as

00:15:03 --> 00:15:05 essential as previously thought for giving birth.

00:15:06 --> 00:15:08 A report in the journal Frontiers and Marine Science

00:15:08 --> 00:15:11 documented newborn calves around Australia and New

00:15:11 --> 00:15:14 Zealand, with the southernmost found at Port Arthur in

00:15:14 --> 00:15:16 Tasmania. That's 1500km further south

00:15:16 --> 00:15:19 than what it was previously thought humpback whales could calve.

00:15:20 --> 00:15:23 And the highest latitude births recorded by humpback whales were

00:15:23 --> 00:15:26 recorded even a little bit further north of Kaikoura in

00:15:26 --> 00:15:29 New Zealand. The authors say it's very likely that

00:15:29 --> 00:15:32 this pattern of births along the so called humpback highways

00:15:32 --> 00:15:34 always existed, but it was obscured when the population

00:15:34 --> 00:15:37 crashed due to whaling. A

00:15:37 --> 00:15:40 Microsoft artificial intelligence called Aurora has

00:15:40 --> 00:15:43 been shown to outperform existing Earth system forecasts

00:15:43 --> 00:15:46 predicting extreme events including weather, air quality,

00:15:46 --> 00:15:48 ocean currents, sea ice and hurricanes.

00:15:49 --> 00:15:52 Existing methods need to analyze decades worth of

00:15:52 --> 00:15:55 data that require huge amounts of computing power.

00:15:55 --> 00:15:58 A report in the journal Nature claims all that data was

00:15:58 --> 00:16:01 fed into aurora and the AI successfully

00:16:01 --> 00:16:04 outperformed seven forecasting centers in predicting the route

00:16:04 --> 00:16:06 of cyclones five days in advance with

00:16:06 --> 00:16:08 100% accuracy and 92%

00:16:08 --> 00:16:11 accuracy for 10 day forecasts. Even

00:16:11 --> 00:16:14 better, training Aurora only took two months, whereas

00:16:14 --> 00:16:17 existing methods can take years. Of course it was

00:16:17 --> 00:16:20 only possible to train the AI so quickly because all that

00:16:20 --> 00:16:23 data used to train the AI had already been collected

00:16:23 --> 00:16:25 by existing Earth, forecasting centers.

00:16:26 --> 00:16:29 Google have held their major artificial intelligence

00:16:29 --> 00:16:32 showcase IO 2025 with

00:16:32 --> 00:16:34 the details. We're joined by technology editor Alex Zaharov-Reutt

00:16:34 --> 00:16:36 Vroit from TechAdvice start live.

00:16:37 --> 00:16:39 Alex Zaharov-Reutt: Yes, well they've had their major Google IO

00:16:39 --> 00:16:42 2025 event and this is where they announced

00:16:42 --> 00:16:45 a lot of new things about AI. So one of

00:16:45 --> 00:16:48 the first changes that people in the US on the

00:16:48 --> 00:16:51 Google homepage instead of seeing the I'm feeling lucky

00:16:51 --> 00:16:53 button it will be AI search. And this is where you're

00:16:53 --> 00:16:56 effectively talking to Gemini and getting a full

00:16:56 --> 00:16:59 AI agent similar to what you get with ChatGPT

00:16:59 --> 00:17:02 or by going to gemini.google.com and it

00:17:02 --> 00:17:05 will expand what you get with the AI

00:17:05 --> 00:17:08 overviews and be a full on assistant right there on

00:17:08 --> 00:17:11 the most famous homepage in the world. You'll also be able

00:17:11 --> 00:17:13 to use that with Google Chrome. It will be able

00:17:13 --> 00:17:16 to navigate multiple tabs for you, be

00:17:16 --> 00:17:19 able to tell you what's on a web page, how you can question

00:17:20 --> 00:17:22 that and talk to it. They were showing a demo where your

00:17:22 --> 00:17:25 assistant could ring up a store and get

00:17:25 --> 00:17:28 information about items in stock and come back to you

00:17:28 --> 00:17:30 and actually take actions for you. Now these are

00:17:30 --> 00:17:33 still coming later this year. I mean, the

00:17:33 --> 00:17:36 Google homepage update is available now for those in the US

00:17:36 --> 00:17:39 The Gemini Live app itself, that gives you the ability

00:17:39 --> 00:17:42 to not just speak to the chatbot like you could

00:17:42 --> 00:17:45 with ChatGPT or Grok, but also now you can see. So

00:17:45 --> 00:17:48 we've spoken about this before, but this previously was made

00:17:48 --> 00:17:51 exclusive to the S25 range and we

00:17:51 --> 00:17:54 Google Pixel phones. Now it's expanded to more Android phones and now

00:17:54 --> 00:17:57 it's available to all effectively modern Androids going, back

00:17:57 --> 00:18:00 several years and also iOS. Now I have tested

00:18:00 --> 00:18:02 it on my phone with iOS and I don't have the

00:18:02 --> 00:18:05 camera icon there yet. It's probably something that is waiting for an

00:18:05 --> 00:18:08 update to come. But you'll be able to hold your phone

00:18:08 --> 00:18:11 up to anything and ask questions about it, identify

00:18:11 --> 00:18:14 plants, animals, looking at instructions on how

00:18:14 --> 00:18:17 to put together some Ikea furniture, whatever it might

00:18:17 --> 00:18:20 be. This is like talking to a robot,

00:18:20 --> 00:18:23 except you're holding the phone in your hand. But there's plenty more.

00:18:23 --> 00:18:26 I mean, Google Beam is an update for Project

00:18:26 --> 00:18:28 Starlight, which was the ability to talk to people

00:18:29 --> 00:18:31 in what appeared to be like a 3D way,

00:18:31 --> 00:18:34 even though you were sitting in front of a 2D television

00:18:34 --> 00:18:37 screen. Now HP is going to launch these big TV screens,

00:18:37 --> 00:18:40 slash monitors with six cameras that will take images from

00:18:40 --> 00:18:43 various viewpoints around you and simulate

00:18:43 --> 00:18:46 a 3D image. So you will feel as though you are actually

00:18:46 --> 00:18:49 talking to that person in a way that is more engaging

00:18:49 --> 00:18:51 and more real than just the way we are do

00:18:51 --> 00:18:54 with Zoom and Google Meet and facetime and

00:18:54 --> 00:18:57 Skype. Another example of Google's

00:18:57 --> 00:19:00 prowess was with the Google Meet Zoom equivalent

00:19:00 --> 00:19:03 where somebody was speaking in Spanish, somebody was speaking in

00:19:03 --> 00:19:05 English, and a couple of seconds after you start speaking in

00:19:06 --> 00:19:08 your language, it's being converted into

00:19:08 --> 00:19:11 Spanish. If you're speaking English and it's being done in

00:19:11 --> 00:19:14 your tone of voice. In the demo it was

00:19:14 --> 00:19:17 very quick and lifelike, is effectively pretty much in

00:19:17 --> 00:19:20 real time. Updates to Imagen 4,

00:19:20 --> 00:19:23 the image editor, VO3, the video editor,

00:19:23 --> 00:19:25 were now delivering much more realistic images.

00:19:26 --> 00:19:29 And with the video it could pair that with audio

00:19:29 --> 00:19:31 that would match the physics of what was on screen. So they had a

00:19:31 --> 00:19:34 gentleman in a boat, the waves were crashing, or just

00:19:34 --> 00:19:37 moving and you could hear them. It was very realistic.

00:19:37 --> 00:19:40 And they've actually now got a thing called Flow, which takes all

00:19:40 --> 00:19:43 of their tools together and can make movies for you just

00:19:43 --> 00:19:46 by describing each scene. And you can extend a scene

00:19:46 --> 00:19:49 and export the clips. Really quite incredible.

00:19:49 --> 00:19:51 Also an Android XR headset that's

00:19:51 --> 00:19:54 extended reality being made with Samsung and

00:19:54 --> 00:19:57 Qualcomm, looks very much like the Apple Vision

00:19:57 --> 00:19:59 Pro, except of course it's running Android. And then also

00:19:59 --> 00:20:02 these glasses looking like a pair of black rimmed ray

00:20:02 --> 00:20:05 bands for example. And there was a camera and you could talk

00:20:05 --> 00:20:08 to Gemini and you could see images

00:20:08 --> 00:20:11 that popped up and were translucent so you could see through them, but they were

00:20:11 --> 00:20:14 in your field of view. You could pick up a map, for example, and

00:20:14 --> 00:20:17 see the directions. If you look down, you would actually see a little

00:20:17 --> 00:20:20 map displayed there, could speak and see subtitles of

00:20:20 --> 00:20:23 what somebody else was saying and have that translated into

00:20:23 --> 00:20:26 another language. Lyria 2 was audio. It was part

00:20:26 --> 00:20:29 of the suite that creates the videos and that was able to make this

00:20:29 --> 00:20:31 orchestral beautiful sounding rich music.

00:20:31 --> 00:20:34 Pretty amazing stuff. It's effectively all available

00:20:35 --> 00:20:37 now. How long it will take until it comes to Australia is yet to

00:20:37 --> 00:20:40 be seen. The Flow video creation tool is

00:20:40 --> 00:20:43 part of Google Gemini Ultra.

00:20:43 --> 00:20:45 Now this is in US dollars,

00:20:45 --> 00:20:48 $249.99 a month. First

00:20:48 --> 00:20:50 three months are at half price. There was a pro

00:20:50 --> 00:20:53 version for about 20 bucks and that's

00:20:53 --> 00:20:56 clearly it's free as well. But if you want more rate

00:20:56 --> 00:20:58 limits as it were, and the ability to do more with

00:20:58 --> 00:21:01 the latest tools as they come out, I mean this is next level stuff.

00:21:02 --> 00:21:04 Stuart Gary: That's Alex Zaharov-Reutt Vroid from TechAdvice
