00:00:00 --> 00:00:02 Anna: Welcome to Astronomy Daily, your ultimate guide to

00:00:02 --> 00:00:05 the latest in space and astronomy news. I'm

00:00:05 --> 00:00:08 Anna, your host and today we're diving into the

00:00:08 --> 00:00:11 groundbreaking visual evidence of a star's double

00:00:11 --> 00:00:13 detonation demise, shedding new light on

00:00:13 --> 00:00:16 cosmic expansion. Then we'll

00:00:16 --> 00:00:19 explore how revolutionary algae bioplastics could

00:00:19 --> 00:00:21 enable self sustaining habitats on Mars.

00:00:22 --> 00:00:24 For all you skywatchers, I'll share how you can spot

00:00:24 --> 00:00:27 both the International Space Station and and China's

00:00:27 --> 00:00:30 Tiangong Station in the pre dawn sky. This week. We'll

00:00:30 --> 00:00:33 also discuss a new study suggesting the universe might be headed

00:00:33 --> 00:00:35 for a big crunch in billions of years.

00:00:36 --> 00:00:39 And finally, we'll talk about the largest piece of Mars ever

00:00:39 --> 00:00:42 found on Earth. A massive rock set for auction

00:00:42 --> 00:00:43 and the debate surrounding it.

00:00:44 --> 00:00:46 It's going to be an exciting journey, so let's get

00:00:46 --> 00:00:49 started. For the first time

00:00:49 --> 00:00:52 ever, astronomers have captured stunning visual

00:00:52 --> 00:00:55 evidence of a star's dramatic exit, a

00:00:55 --> 00:00:57 double detonation that marks its explosive death.

00:00:58 --> 00:01:01 This groundbreaking discovery centres around a type of

00:01:01 --> 00:01:03 stellar explosion known as a type 1a

00:01:03 --> 00:01:06 supernova, which plays an absolutely crucial role

00:01:06 --> 00:01:09 in our understanding of the universe. These

00:01:09 --> 00:01:12 specific supernovas are not just spectacular cosmic

00:01:12 --> 00:01:15 fireworks. They are vital for accurately measuring

00:01:15 --> 00:01:18 the universe's expansion rate, a topic currently

00:01:18 --> 00:01:20 at the heart of a major cosmological debate.

00:01:21 --> 00:01:24 What's more, type 1A supernovas are also the primary

00:01:24 --> 00:01:27 source of iron found throughout the cosmos, making

00:01:27 --> 00:01:30 their explosion mechanisms a puzzle astronomers are

00:01:30 --> 00:01:33 keen to solve. The evidence for this twin eruption

00:01:33 --> 00:01:35 was found by scientists studying two concentric rings of

00:01:35 --> 00:01:36 calcium surrounding

00:01:36 --> 00:01:40 SNR0509.67.5,

00:01:40 --> 00:01:43 which is the remnant of a star that met its explosive end

00:01:43 --> 00:01:46 centuries ago. While astronomers have long theorised that

00:01:46 --> 00:01:48 white dwarfs, the dense husks of dead stars,

00:01:49 --> 00:01:51 typically explode after steadily accumulating material from

00:01:51 --> 00:01:54 a companion star until they reach a critical mass known

00:01:54 --> 00:01:57 as the Chandrasekhar limit. Hints have suggested other

00:01:57 --> 00:02:00 mechanisms might be at play. Using the

00:02:00 --> 00:02:03 European Southern Observatory's Very Large Telescope,

00:02:03 --> 00:02:06 researchers found those two distinct calcium rings,

00:02:06 --> 00:02:09 which offer clear proof that white dwarfs can indeed

00:02:09 --> 00:02:12 detonate well before reaching the Chandrasekhar mass limit.

00:02:12 --> 00:02:15 This confirms the existence of the double detonation

00:02:15 --> 00:02:18 mechanism in nature. The proposed scenario

00:02:18 --> 00:02:21 is fascinating. The white dwarf first blankets

00:02:21 --> 00:02:24 itself in stolen helium from its neighbour.

00:02:24 --> 00:02:27 This helium then ignites, sending a shockwave

00:02:27 --> 00:02:30 inward that causes the dead star's core to ignite in a

00:02:30 --> 00:02:32 second, much larger explosion. Studying

00:02:32 --> 00:02:35 these dual detonations has profound implications,

00:02:36 --> 00:02:39 particularly for how we use type 1A supernovas as

00:02:39 --> 00:02:41 standard candles, cosmic benchmarks that

00:02:41 --> 00:02:44 explode with consistent Brightness, allowing

00:02:44 --> 00:02:47 astronomers to measure vast distances and calculate the

00:02:47 --> 00:02:49 universe's expansion rate. This tangible

00:02:49 --> 00:02:52 evidence not only helps solve a ah, long standing

00:02:52 --> 00:02:55 mystery, but also offers a truly visual

00:02:55 --> 00:02:58 spectacle revealing the inner workings of such a

00:02:58 --> 00:02:59 dramatic cosmic event.

00:03:00 --> 00:03:03 Moving on, let's head over to Mars. Imagine building a

00:03:03 --> 00:03:06 home on Mars that literally grows itself. It sounds

00:03:06 --> 00:03:09 like something out of science fiction, but scientists are making

00:03:09 --> 00:03:11 strides towards this very possibility with a

00:03:11 --> 00:03:14 revolutionary new bioplastic derived from green

00:03:14 --> 00:03:17 algae. This innovation could be a game changer for

00:03:17 --> 00:03:20 human missions to other worlds, tackling the immense

00:03:20 --> 00:03:23 challenge and cost of transporting building materials from

00:03:23 --> 00:03:26 Earth. The concept is elegantly simple.

00:03:26 --> 00:03:29 If a habitat is constructed from this bioplastic and it can

00:03:29 --> 00:03:32 grow algae within its structure, that algae can then

00:03:32 --> 00:03:35 produce even more bioplastic. This creates a

00:03:35 --> 00:03:37 self sustaining closed loop system that could allow

00:03:37 --> 00:03:40 extraterrestrial settlements to not only sustain themselves,

00:03:40 --> 00:03:43 but also expand over time. It truly

00:03:43 --> 00:03:46 echoes the living ships seen in sci fi

00:03:46 --> 00:03:48 classics like Stargate Atlantis or Star Trek.

00:03:49 --> 00:03:51 In lab experiments, researchers successfully

00:03:51 --> 00:03:54 recreated the challenging atmospheric conditions of

00:03:54 --> 00:03:56 Mars, where the air pressure is significantly

00:03:56 --> 00:03:59 lower and the atmosphere is rich in carbon

00:03:59 --> 00:04:02 dioxide. Despite these harsh conditions,

00:04:02 --> 00:04:04 a common green algae called Dunaliella

00:04:04 --> 00:04:07 tertiolecta thrived inside a 3D

00:04:07 --> 00:04:09 printed growth chamber made from this new

00:04:09 --> 00:04:12 bioplastic, which is a type of polylactic

00:04:12 --> 00:04:15 acid. The bioplastic material proved

00:04:15 --> 00:04:18 crucial, blocking harmful UV radiation

00:04:18 --> 00:04:20 while still allowing enough light to penetrate for

00:04:20 --> 00:04:23 photosynthesis. Critically, the chamber also

00:04:23 --> 00:04:26 created a pressure gradient that allowed liquid water to

00:04:26 --> 00:04:29 stabilise within its walls, a key element for life

00:04:29 --> 00:04:31 that is otherwise unstable on the Martian surface.

00:04:32 --> 00:04:35 This research indicates that even on seemingly barren

00:04:35 --> 00:04:38 worlds, organic growth could be harnessed to construct human

00:04:38 --> 00:04:41 habitats. This builds upon previous work by

00:04:41 --> 00:04:43 the same team, which showed that sheets of silica

00:04:43 --> 00:04:46 aerogels could mimic Earth's greenhouse effect to

00:04:46 --> 00:04:49 enable biological growth on other planets.

00:04:49 --> 00:04:52 Combining these two lines of research could pave the way

00:04:52 --> 00:04:55 for a truly sustainable human presence beyond

00:04:55 --> 00:04:58 Earth. The next step for the team is to demonstrate that

00:04:58 --> 00:05:00 these bioplastic habitats can be grown in a vacuum,

00:05:01 --> 00:05:04 simulating conditions for missions to other deep space

00:05:04 --> 00:05:06 locations like the Moon.

00:05:07 --> 00:05:09 Beyond the exciting prospects for space exploration,

00:05:10 --> 00:05:13 this kind of biomaterial technology is expected

00:05:13 --> 00:05:16 to have significant spin off benefits for sustainability here

00:05:16 --> 00:05:18 on Earth, offering innovative solutions for our own

00:05:18 --> 00:05:19 planet's future.

00:05:20 --> 00:05:23 Okay, let's make a quick trip back to Earth. For

00:05:23 --> 00:05:26 skywatchers across most of the US and southern Canada,

00:05:26 --> 00:05:29 and indeed for many in North America and Europe, there's

00:05:29 --> 00:05:32 a fantastic opportunity this week to witness two of

00:05:32 --> 00:05:35 humanity's largest orbiting outposts within minutes

00:05:35 --> 00:05:37 of each other. I'm talking about the International Space

00:05:37 --> 00:05:40 Station or iss, and China's Tiangong

00:05:40 --> 00:05:43 Space Station. If you're up during the pre dawn

00:05:43 --> 00:05:46 hours, you might even catch both in the sky at the same

00:05:46 --> 00:05:49 time on certain mornings. It's truly

00:05:49 --> 00:05:52 remarkable how many satellites now orbit Earth, though.

00:05:52 --> 00:05:55 Most of the over 30 objects are

00:05:55 --> 00:05:57 space junk, too small to see with the unaided

00:05:57 --> 00:06:00 eye. But there are about 500 that are large

00:06:00 --> 00:06:02 enough and low enough in orbit to be visible.

00:06:03 --> 00:06:06 As the distinguished British scientist Desmond King Healy

00:06:06 --> 00:06:09 once put it, a satellite looks like a star that has

00:06:09 --> 00:06:12 taken leave of its senses and decided to move off to another part

00:06:12 --> 00:06:15 of the sky. The International Space

00:06:15 --> 00:06:17 Station is by far the biggest and brightest of these man made

00:06:17 --> 00:06:20 objects. Imagine something almost the length of

00:06:20 --> 00:06:23 a football field, including the end zones.

00:06:23 --> 00:06:26 Powered by solar arrays longer than a Boeing

00:06:26 --> 00:06:28 777's wingspan.

00:06:29 --> 00:06:31 Orbiting at an average altitude of about

00:06:31 --> 00:06:34 416 kilometres and moving at a

00:06:34 --> 00:06:37 staggering 28 kilometres per hour,

00:06:37 --> 00:06:40 the ISS completes roughly 15.5

00:06:40 --> 00:06:42 orbits per day. Because of its massive

00:06:42 --> 00:06:45 size and highly reflective solar panels, it

00:06:45 --> 00:06:48 can appear up to two and a half times brighter than Venus

00:06:48 --> 00:06:51 and sometimes even flare to an incredible

00:06:51 --> 00:06:53 magnitude, making it much brighter than any star.

00:06:54 --> 00:06:57 Then there's Tiangong, China's Heavenly Palace Space

00:06:57 --> 00:07:00 Station. While smaller than the ISS,

00:07:00 --> 00:07:03 about 1/5 the size, it's still a prominent

00:07:03 --> 00:07:06 object in the night sky. It orbits at a slightly

00:07:06 --> 00:07:09 lower altitude of about 393 kilometres

00:07:09 --> 00:07:12 and can appear as bright as Venus or Jupiter on its

00:07:12 --> 00:07:15 most favourable passes. Currently,

00:07:15 --> 00:07:18 between the ISS and Tiangong, there are

00:07:18 --> 00:07:20 14 humans living and working in space.

00:07:21 --> 00:07:24 Now, if you're wondering when and where to look, it's easier

00:07:24 --> 00:07:27 than you might think. From now through the end of

00:07:27 --> 00:07:30 July, North Americans and Europeans will have

00:07:30 --> 00:07:32 numerous chances to spot both stations,

00:07:33 --> 00:07:36 primarily because nights are shorter, allowing these

00:07:36 --> 00:07:39 low Earth orbit satellites to remain illuminated by the

00:07:39 --> 00:07:41 sun for longer periods. Since

00:07:41 --> 00:07:44 both stations circle earth roughly every 90

00:07:44 --> 00:07:46 minutes, you might even catch them on several

00:07:46 --> 00:07:49 consecutive passes. They have slightly different

00:07:49 --> 00:07:52 orbital altitudes and inclinations, which

00:07:52 --> 00:07:55 makes seeing them simultaneously a less common event. But

00:07:55 --> 00:07:58 it is possible to find out the exact

00:07:58 --> 00:08:01 viewing schedule for your specific location. I highly

00:08:01 --> 00:08:04 recommend visiting either Chris Peet's Heavens above website or

00:08:04 --> 00:08:07 NASA's spot the station. Both are excellent

00:08:07 --> 00:08:09 resources. Heavens above allows you to input your

00:08:09 --> 00:08:12 precise latitude and longitude to generate accurate

00:08:12 --> 00:08:15 sighting data for both the ISS and Tiangong.

00:08:15 --> 00:08:18 NASA's Spot the Station offers a

00:08:18 --> 00:08:21 widget where you simply enter your location and it

00:08:21 --> 00:08:24 provides details like the time of the flyover, how long it

00:08:24 --> 00:08:26 will be visible, its maximum height in the sky,

00:08:26 --> 00:08:29 and the direction it will appear and disappear from your

00:08:29 --> 00:08:32 view. Just remember that predictions can change

00:08:32 --> 00:08:35 slightly due to orbital adjustments, so it's a good idea to

00:08:35 --> 00:08:37 check frequently for updates. Happy sky

00:08:37 --> 00:08:38 gazing.

00:08:39 --> 00:08:42 Next up, let's talk about an old, yet mysterious

00:08:43 --> 00:08:45 dark energy for generations,

00:08:45 --> 00:08:48 humanity has looked up at the stars and pondered the ultimate

00:08:48 --> 00:08:51 fate of our universe. Will it expand forever

00:08:51 --> 00:08:54 into the cold, empty vastness, or is there a more dramatic

00:08:54 --> 00:08:56 end in store? A new study published by

00:08:56 --> 00:08:59 physicists from Cornell University, Shanghai, Jiao

00:08:59 --> 00:09:02 Tong University, and other institutions suggests

00:09:02 --> 00:09:05 we might finally have a surprising and specific answer.

00:09:05 --> 00:09:08 Using data from several astronomical surveys, including

00:09:08 --> 00:09:11 the Dark Energy Survey and the Dark Energy

00:09:11 --> 00:09:13 Spectroscopic Instrument, researchers have

00:09:13 --> 00:09:16 developed a model that predicts our universe will meet

00:09:16 --> 00:09:19 its end in a big crunch in approximately

00:09:19 --> 00:09:21 33.3 billion years.

00:09:22 --> 00:09:25 Considering the universe is currently 13.8

00:09:25 --> 00:09:28 billion years old, this gives us roughly 20

00:09:28 --> 00:09:31 billion years before the curtain falls. This

00:09:31 --> 00:09:33 prediction challenges the long held assumption that the

00:09:33 --> 00:09:36 universe will expand indefinitely.

00:09:36 --> 00:09:39 Instead, it suggests that after reaching its maximum

00:09:39 --> 00:09:42 expansion in about 7 billion years, the

00:09:42 --> 00:09:45 universe will begin to contract until everything eventually

00:09:45 --> 00:09:48 collapses back into a single point. The key

00:09:48 --> 00:09:51 to this theory lies in understanding dark energy, the

00:09:51 --> 00:09:54 mysterious force that makes up about 70% of the

00:09:54 --> 00:09:56 universe and drives its expansion.

00:09:57 --> 00:09:59 For a long time, it was assumed that dark energy behaved like a

00:09:59 --> 00:10:02 cosmological constant, maintaining a steady

00:10:02 --> 00:10:05 pressure that pushed space apart indefinitely.

00:10:05 --> 00:10:08 However, recent observations hint that dark energy

00:10:08 --> 00:10:11 might actually be dynamic. The researchers

00:10:11 --> 00:10:14 propose a model involving an ultralight particle called

00:10:14 --> 00:10:16 an axion, combined with what's known as a

00:10:16 --> 00:10:19 negative cosmological constant. You can think of it

00:10:19 --> 00:10:22 like a massive rubber band. Initially, the universe

00:10:22 --> 00:10:25 expands as this rubber band stretches, but

00:10:25 --> 00:10:27 eventually the elastic force becomes stronger than the

00:10:27 --> 00:10:30 expansion, causing everything to snap back together.

00:10:31 --> 00:10:34 According to this new model, the universe will continue

00:10:34 --> 00:10:37 expanding, but at a gradually slowing rate

00:10:37 --> 00:10:39 until it reaches its maximum size, about

00:10:39 --> 00:10:42 69% larger than today in roughly

00:10:42 --> 00:10:45 7 billion years. Then gradual

00:10:45 --> 00:10:48 contraction will begin as gravitational forces

00:10:48 --> 00:10:51 and the negative cosmological constant take

00:10:51 --> 00:10:54 over, leading to a rapid collapse in the final

00:10:54 --> 00:10:57 moments. It's important to note that this

00:10:57 --> 00:10:59 prediction comes with significant uncertainty.

00:11:00 --> 00:11:02 The researchers acknowledge that their model has large

00:11:02 --> 00:11:05 margins of error due to limited observational

00:11:05 --> 00:11:08 data, and the negative cosmological

00:11:08 --> 00:11:10 constant that drives their prediction remains highly

00:11:10 --> 00:11:13 speculative. Alternative scenarios, including

00:11:13 --> 00:11:16 eternal expansion, are still very much on the table.

00:11:17 --> 00:11:20 What makes this research particularly exciting is

00:11:20 --> 00:11:23 isn't just the prediction itself, but the fact

00:11:23 --> 00:11:25 that we may soon be able to test it.

00:11:26 --> 00:11:29 Several m major astronomical projects Launching in the

00:11:29 --> 00:11:31 coming years are set to provide much more

00:11:31 --> 00:11:34 precise measurements of dark energy's behaviour.

00:11:35 --> 00:11:38 These future observations could potentially confirm,

00:11:38 --> 00:11:41 refine or even rule out the Big Crunch

00:11:41 --> 00:11:44 scenario entirely once and for all.

00:11:44 --> 00:11:47 Even if confirmed, a 20 billion year countdown

00:11:47 --> 00:11:50 hardly constitutes an immediate crisis for us.

00:11:50 --> 00:11:53 To put it in perspective, complex life on Earth has only

00:11:53 --> 00:11:55 existed for about 600 million years.

00:11:56 --> 00:11:59 20 billion years represents a time frame so vast

00:11:59 --> 00:12:02 that our sun will have died and our galaxy will have

00:12:02 --> 00:12:04 collided with Andromeda long before any cosmic collapse

00:12:04 --> 00:12:07 even begins. Nevertheless, this

00:12:07 --> 00:12:10 research represents a remarkable achievement in our

00:12:10 --> 00:12:12 understanding of the cosmos, providing us with a

00:12:12 --> 00:12:15 concrete timeline for what could be the most dramatic event possible.

00:12:16 --> 00:12:18 The end of the universe itself.

00:12:19 --> 00:12:22 Shifting gears from the vast cosmic scale to something

00:12:22 --> 00:12:25 a little closer to home, or at least closer to Earth,

00:12:25 --> 00:12:28 we have a fascinating story about a very special

00:12:28 --> 00:12:31 rock. The most massive piece of Mars ever

00:12:31 --> 00:12:33 found here on Earth could soon sell for up to US$4 million

00:12:34 --> 00:12:37 in a Sotheby's auction later this month. This

00:12:37 --> 00:12:40 incredible meteorite, officially named NWA

00:12:40 --> 00:12:42 16788, weighs a staggering

00:12:42 --> 00:12:45 24.67 kilogrammes, or about

00:12:45 --> 00:12:47 54.39 pounds. That makes it

00:12:47 --> 00:12:50 approximately 70% larger than the previous

00:12:50 --> 00:12:53 record holder, another Martian meteorite found

00:12:53 --> 00:12:55 in mali back in 2021.

00:12:56 --> 00:12:59 This massive chunk of Mars was discovered by a

00:12:59 --> 00:13:02 meteorite hunter in November 2023

00:13:02 --> 00:13:05 in the sparsely populated Agadez region of Niger,

00:13:06 --> 00:13:09 an area more renowned for its dinosaur fossils

00:13:09 --> 00:13:11 than its meteorites. The Shanghai

00:13:11 --> 00:13:14 Astronomy Museum confirmed the rock's Martian

00:13:14 --> 00:13:17 identity after a small sample was sent there. And

00:13:17 --> 00:13:20 now this interplanetary treasure has a significant price

00:13:20 --> 00:13:22 tag. According to the Sotheby's listing,

00:13:22 --> 00:13:25 the meteorite shows minimal terrestrial

00:13:25 --> 00:13:28 weathering, which means its physical and chemical makeup

00:13:28 --> 00:13:31 haven't been significantly altered since it landed in the

00:13:31 --> 00:13:33 Sahara Desert. In other words,

00:13:33 --> 00:13:34 NWA 16

00:13:36 --> 00:13:39 is likely a relatively recent arrival on Earth,

00:13:39 --> 00:13:41 having fallen from outer space not too long ago.

00:13:42 --> 00:13:45 Its characteristics tell us a lot about its journey.

00:13:45 --> 00:13:47 Based on a high percentage of a glass called

00:13:47 --> 00:13:50 maskelynite, along with some shock melted areas,

00:13:51 --> 00:13:54 scientists believe this rock was likely sent hurtling

00:13:54 --> 00:13:56 through space when a severe asteroid crashed into

00:13:56 --> 00:13:59 Mars. The Sotheby's listing further explains

00:13:59 --> 00:14:02 that the meteorite was formed from the slow cooling

00:14:02 --> 00:14:05 of Martian magma and and is characterised by a

00:14:05 --> 00:14:08 coarse grained texture, primarily composed of

00:14:08 --> 00:14:10 pyroxene, masculinite and

00:14:10 --> 00:14:13 olivine. However, the sale of such a

00:14:13 --> 00:14:16 rare specimen has sparked a debate among some

00:14:16 --> 00:14:19 scientists. Palaeontologist Steve

00:14:19 --> 00:14:21 Brusot from the University of Edinburgh

00:14:21 --> 00:14:24 expressed concern to CNN stating that it would

00:14:24 --> 00:14:26 be a shame if it disappeared into the vault of an

00:14:26 --> 00:14:29 oligarch, suggesting it belongs in a museum

00:14:29 --> 00:14:31 where it can be studied and enjoyed by the public.

00:14:32 --> 00:14:35 On the other hand, planetary scientist Julia Cartwright

00:14:35 --> 00:14:38 from the University of Leicester offered a different

00:14:38 --> 00:14:41 perspective, telling CNN that the scientific

00:14:41 --> 00:14:44 interest will remain and the new owner may be

00:14:44 --> 00:14:47 very interested in learning from it, meaning we could

00:14:47 --> 00:14:49 still gather a lot of science from this unique find.

00:14:50 --> 00:14:53 The Sotheby's auction is scheduled to begin on July

00:14:53 --> 00:14:53 16th.

00:14:55 --> 00:14:58 That brings us to the end of another fascinating episode of
