0:00 Speaker 1: Welcome to Astronomy Daily, your daily source for the latest

0:02 Speaker 1: space in astronomy news. I'm your host, Anna, and we've

0:06 Speaker 1: gotten great lineup of stories for you today. From revolutionary

0:09 Speaker 1: signal detection technology in Australia to groundbreaking discoveries by the

0:13 Speaker 1: James Webb Space Telescope, We're covering the full spectrum of

0:16 Speaker 1: astronomical advancement. We'll explore how Kracko, a cutting edge telescope system,

0:22 Speaker 1: is transforming our ability to detect cosmic signals, and we'll

0:26 Speaker 1: get up to speed with this week's packed launch schedule

0:29 Speaker 1: featuring missions from major space agencies around the globe. The

0:33 Speaker 1: James Webb Space Telescope continues to astound us with its

0:36 Speaker 1: discoveries of massive black holes in the early universe, challenging

0:40 Speaker 1: our understanding of cosmic evolution. We'll also delve into fascinating

0:44 Speaker 1: new research about the universe's first stars and share surprising

0:48 Speaker 1: findings about Martian wind speeds from the Ingenuity Helicopter. Plus,

0:53 Speaker 1: we'll look ahead to the exciting prospects of the Vera

0:55 Speaker 1: Reuben Observatory and its potential to revolutionize our understanding of

1:00 Speaker 1: dark energy. Stay with us as we journey through these

1:03 Speaker 1: remarkable developments in space exploration and astronomical discovery. Let's get started.

1:10 Speaker 1: In a groundbreaking development from Australia, Astronomers and engineers at

1:14 Speaker 1: CSIRO have unveiled Kracko, a revolutionary telescope technology that's transforming

1:20 Speaker 1: our ability to detect mysterious signals from deep space. Think

1:24 Speaker 1: of it as a cosmic treasure hunter, sifting through an

1:26 Speaker 1: astronomical amount of data to find rare cosmic events with

1:30 Speaker 1: remarkable precision. To put its capabilities into perspective, Cracko processes

1:35 Speaker 1: an astounding one hundred billion pixels per second that's equivalent

1:39 Speaker 1: to searching through an entire beach of sand every minute

1:42 Speaker 1: to find a single five cent coin. This incredible processing

1:46 Speaker 1: power has already led to several major discoveries, including multiple

1:50 Speaker 1: fast radio bursts and the detection of two previously unknown

1:54 Speaker 1: neutron stars. During its initial trial run, the system surpassed

1:58 Speaker 1: all expectations. Doctor Andy Wang and his team at the

2:02 Speaker 1: International Center for Radio Astronomy Research have already used Kracko

2:05 Speaker 1: to identify more than twenty fast radio bursts, mysterious cosmic

2:10 Speaker 1: phenomena that have puzzled astronomers for years. The system can

2:13 Speaker 1: search for these bursts one hundred times per second, with

2:16 Speaker 1: plans to increase this to an impressive one thousand times

2:19 Speaker 1: per second in the future. The technology operates as part

2:23 Speaker 1: of the ASCAP Radio Telescope at in yarimanha Ilgari Bundhara,

2:27 Speaker 1: the CSIRO Murchison Radio Astronomy Observatory. What makes KRACKO particularly

2:32 Speaker 1: special is its ability to instantly alert researchers when it

2:35 Speaker 1: detects something unusual, allowing for immediate follow up observations and analysis.

2:41 Speaker 1: This technological breakthrough isn't just about finding cosmic signals, it's

2:45 Speaker 1: about understanding them. KRACKO has already helped detect long period

2:49 Speaker 1: transience mysterious objects within our galaxy that we're only beginning

2:53 Speaker 1: to understand. These discoveries are reinforcing Australia's position as a

2:58 Speaker 1: leader in radio astronomy engineering and research, with the technology

3:02 Speaker 1: soon to be made available to astronomers worldwide through csio's

3:06 Speaker 1: Australia Telescope National Facility. The implications of this technology extend

3:10 Speaker 1: far beyond its immediate discoveries, by providing astronomers with unprecedented

3:14 Speaker 1: capabilities to detect and analyze cosmic signals Kracko is opening

3:19 Speaker 1: new windows into understanding the universe's most enigmatic phenomena, from

3:23 Speaker 1: the nature of fast radio bursts to the behavior of

3:26 Speaker 1: neutron stars. Now, let's take a look at what's headed

3:30 Speaker 1: for space this coming week. And this week's launch schedule

3:33 Speaker 1: is packed with activity across multiple continents, showcasing the increasingly

3:37 Speaker 1: busy nature of our space industry. SpaceX leads the charge

3:41 Speaker 1: with four planned missions utilizing all three of their active

3:45 Speaker 1: launch sites. Among these are multiple Starlink satellite deployments, continuing

3:50 Speaker 1: their efforts to expand global Internet coverage. Blue Origin is

3:54 Speaker 1: preparing for a fascinating, uncrude New Shepherd flight that will

3:58 Speaker 1: carry out groundbreaking research. The mission will host thirty payloads,

4:02 Speaker 1: with NASA contributing seventeen different experiments designed to test technologies

4:07 Speaker 1: for future lunar missions. What makes this flight particularly interesting

4:12 Speaker 1: is its ability to simulate lunar gravity conditions. The capsule

4:16 Speaker 1: will spin at approximately eleven revolutions per minute, creating an

4:20 Speaker 1: environment that mimics the Moon's gravitational pull for about two minutes,

4:24 Speaker 1: significantly longer than previous simulation methods. India Space Agency ISRO

4:29 Speaker 1: is set to launch their NVS zero two navigation satellite

4:34 Speaker 1: aboard a GSLV Mark two rocket. This satellite will join

4:38 Speaker 1: India's navic constellation, providing enhanced positioning accuracy across the Indian

4:43 Speaker 1: subcontinent and extending roughly one thousan five hundred kilometers beyond

4:47 Speaker 1: its borders. The satellite carries cutting edge technology, including an

4:51 Speaker 1: indigenous atomic clock that uses rubidium atoms for ultra precise timekeeping. Meanwhile,

4:57 Speaker 1: Japan is preparing to launch their H three rocket carrying

5:00 Speaker 1: the Mitchibiki six navigation satellite, which aims to improve GPS

5:04 Speaker 1: accuracy from meters to centimeter level precision. The Spanish military

5:09 Speaker 1: is also joining the launch manifest with their next generation

5:12 Speaker 1: telecommunication satellite spainsat NGNG one, scheduled for deployment aboard a

5:17 Speaker 1: Falcon nine rocket. Lab rounds out the schedule with another

5:20 Speaker 1: commercial launch from their New Zealand facility, continuing their series

5:24 Speaker 1: of missions for French customer Quinais. This diverse array of

5:28 Speaker 1: launches demonstrates how space access has become increasingly routine and

5:32 Speaker 1: commercially vital, with applications ranging from navigation and communication to

5:36 Speaker 1: scientific research and technological demonstration. The pace of launches we're

5:41 Speaker 1: seeing this month suggests we might be on track for

5:43 Speaker 1: a record breaking year in orbital missions, highlighting the growing

5:47 Speaker 1: importance of space based infrastructure in our modern world. Next,

5:52 Speaker 1: an exciting update from the JWST. The James Webb Space

5:57 Speaker 1: Telescope has made an extraordinary discovery that's challenging our understanding

6:01 Speaker 1: of the early universe. Astronomers have identified several super massive

6:05 Speaker 1: black holes that appear to be far too massive compared

6:07 Speaker 1: to their host galaxies, breaking the rules we thought we

6:11 Speaker 1: understood about galactic evolution in our nearby universe. Super Massive

6:16 Speaker 1: black holes typically have masses equal to about zero point

6:19 Speaker 1: zero one percent of their host galaxies stellar mass. However,

6:25 Speaker 1: these newly discovered black holes from the early Universe tell

6:27 Speaker 1: a dramatically different story. Statistical calculations show they possess masses

6:33 Speaker 1: equal to roughly ten percent of their host galaxies stellar mass,

6:37 Speaker 1: making them approximately one thousand times more massive than expected.

6:42 Speaker 1: These findings were made possible through Web's observations of what

6:45 Speaker 1: astronomers are calling little red dot galaxies. These peculiar objects

6:50 Speaker 1: existed just one point five billion years after the Big Bang,

6:53 Speaker 1: when the universe was merely eleven percent of its current age.

6:57 Speaker 1: Their reddish appearance comes from the gas and dust rounding

7:00 Speaker 1: actively feeding black holes, creating what we call active galactic nuclei.

7:05 Speaker 1: The discovery could help solve one of astronomy's most perplexing mysteries,

7:09 Speaker 1: how super massive black holes managed to grow to such

7:12 Speaker 1: enormous sizes so quickly in the universe's youth. Traditional theories

7:16 Speaker 1: suggest that black holes should take more than a billion

7:19 Speaker 1: years to reach such massive proportions through standard growth processes

7:23 Speaker 1: like mergers and steady accretion of matter. One possible explanation

7:27 Speaker 1: is that black holes in the early universe grew much

7:30 Speaker 1: more efficiently than their modern counterparts, possibly due to the

7:34 Speaker 1: higher density of gas available in the early cosmos. This

7:38 Speaker 1: environment may have allowed them to consume surrounding matter at

7:41 Speaker 1: rates far exceeding what we observe today. These findings suggest

7:46 Speaker 1: that the formation of stars and super massive black holes

7:49 Speaker 1: in early galaxies might be more intrinsically linked than previously thought.

7:54 Speaker 1: While these ancient black holes appear to have grown at

7:57 Speaker 1: extraordinary rates initially, the star formation in their host galaxies

8:02 Speaker 1: eventually caught up, leading to the more balanced ratios we

8:05 Speaker 1: observe in nearby galaxies. Today, and while we're talking new

8:10 Speaker 1: research findings, new research is shedding fascinating light on two

8:14 Speaker 1: very different aspects of our cosmic neighborhood, from the universe's

8:18 Speaker 1: first stars to the winds on Mars. Let's start with

8:21 Speaker 1: an intriguing study about the earliest stars ever to exist,

8:24 Speaker 1: known as Population three stars. These cosmic giants were thought

8:29 Speaker 1: to be some of the most massive stars ever formed,

8:32 Speaker 1: but scientists have now discovered that their growth wasn't limitless.

8:35 Speaker 1: Through detailed simulations that incorporate magnetic fields, a factor previously overlooked,

8:41 Speaker 1: researchers found that these ancient stars could only grow to

8:44 Speaker 1: about sixty five times the mass of our Sun. This

8:48 Speaker 1: is significantly less than previous estimates that suggested masses of

8:52 Speaker 1: up to one hundred and twenty solar masses when magnetic

8:55 Speaker 1: fields weren't considered. The key finding here is that magnetic

9:00 Speaker 1: fields acted as a natural break on star growth, even

9:03 Speaker 1: before other limiting factors like radiation pressure came into play.

9:07 Speaker 1: These fields worked against gravity, restricting the amount of gas

9:10 Speaker 1: that could fall onto the forming star. This new understanding

9:14 Speaker 1: helps explain why we don't see evidence of even more

9:16 Speaker 1: massive stars in the early universe. Meanwhile, closer to home,

9:21 Speaker 1: NASA's Ingenuity helicopter has been revolutionizing our understanding of Mars's atmosphere.

9:26 Speaker 1: During its remarkable seventy two flights on the red planet,

9:29 Speaker 1: this small but mighty aircraft has recorded wind speeds that

9:32 Speaker 1: are considerably higher than what our models predicted. Previous estimates

9:37 Speaker 1: suggested Martian winds wouldn't exceed fifteen meters per second, but

9:41 Speaker 1: Ingenuity encountered speeds as high as twenty five meters per

9:45 Speaker 1: second at various altitudes between three and twenty four meters

9:49 Speaker 1: above the surface. This discovery was made possible through an

9:53 Speaker 1: ingenious method using the helicopter's own tilt during flight to

9:57 Speaker 1: calculate wind speeds. Just as a drone on Earth needs

10:01 Speaker 1: to tilt into the wind to maintain its position, Ingenuity's

10:04 Speaker 1: tilt measurements provided crucial data about Mars's atmospheric conditions. These

10:09 Speaker 1: findings are particularly valuable for future Mars missions, especially as

10:13 Speaker 1: we plan more aerial vehicles like the upcoming Dragonfly mission

10:17 Speaker 1: to Saturn's moon Titan. Understanding these wind patterns is crucial

10:21 Speaker 1: for designing spacecraft and planning missions that can safely navigate

10:25 Speaker 1: alien atmospheres. Finally today, looking into the future, exciting developments

10:32 Speaker 1: are on the horizon as the Vera Sea Reuben Observatory

10:35 Speaker 1: prepares to begin its operations from its home atop Sarah

10:38 Speaker 1: Paschan in Chile. This cutting edge facility is about to

10:42 Speaker 1: embark on an ambitious ten year survey that promises to

10:45 Speaker 1: revolutionize our understanding of the cosmos, particularly when it comes

10:49 Speaker 1: to exploding stars. Scientists predict the observatory will detect millions

10:53 Speaker 1: of what are playfully nicknamed vampire stars, white dwarfs that

10:58 Speaker 1: steal material from their companion stars until they explode in

11:01 Speaker 1: spectacular fashion. These explosions, known as Type I as supernovas,

11:06 Speaker 1: are particularly valuable to astronomers because they always release the

11:09 Speaker 1: same amount of light, making them perfect cosmic measuring sticks.

11:14 Speaker 1: Think of these supernovas as celestial lampposts. If you know

11:17 Speaker 1: how bright they should be, you can figure out how

11:20 Speaker 1: far away they are by how dim they appear. This

11:23 Speaker 1: makes them crucial tools for understanding how our universe is

11:27 Speaker 1: expanding and the mysterious force behind this expansion, dark energy.

11:32 Speaker 1: The observatory will scan the entire Southern sky every few nights,

11:36 Speaker 1: giving astronomers unprecedented opportunities to catch these stellar explosions in action.

11:42 Speaker 1: It's expected to generate a staggering amount of data, up

11:45 Speaker 1: to ten million alerts embedded in twenty terabytes of information

11:47 Speaker 1: every single night. This wealth of data could help resolve

11:51 Speaker 1: some pressing questions about dark energy, which makes up about

11:54 Speaker 1: sixty eight percent of our universe's energy budget. Recent observations

11:58 Speaker 1: have suggested that dark energy strength might not be constant

12:02 Speaker 1: as previously thought, and the Reuben Observatory's observations could finally

12:06 Speaker 1: help us understand if and how this mysterious force is

12:10 Speaker 1: changing over time. This new era of observation represents a

12:14 Speaker 1: fundamental shift in how we study the cosmos. The sheer

12:18 Speaker 1: volume of data will require new methods of analysis, setting

12:22 Speaker 1: the stage for the next generation of astronomical discoveries and

12:25 Speaker 1: our understanding of the Universe's ultimate fate. And with that

12:30 Speaker 1: we wrap up today's fascinating journey through the Cosmos. Thank
