00:00:00 --> 00:00:02 Anna: Welcome to Astronomy Daily, your ultimate
00:00:02 --> 00:00:04 guide to the latest in space and astronomy
00:00:04 --> 00:00:07 news. I'm Anna, your host and today
00:00:07 --> 00:00:09 we're diving into the groundbreaking visual
00:00:09 --> 00:00:11 evidence of a star's double detonation
00:00:11 --> 00:00:14 demise, shedding new light on cosmic
00:00:14 --> 00:00:17 expansion. Then we'll explore how
00:00:17 --> 00:00:19 revolutionary algae bioplastics could enable
00:00:19 --> 00:00:22 self sustaining habitats on Mars. For all
00:00:22 --> 00:00:24 you skywatchers, I'll share how you can spot
00:00:24 --> 00:00:27 both the International Space Station and and
00:00:27 --> 00:00:29 China's Tiangong Station in the pre dawn sky.
00:00:29 --> 00:00:31 This week. We'll also discuss a new study
00:00:31 --> 00:00:33 suggesting the universe might be headed for a
00:00:33 --> 00:00:36 big crunch in billions of years. And
00:00:36 --> 00:00:38 finally, we'll talk about the largest piece
00:00:38 --> 00:00:41 of Mars ever found on Earth. A massive rock
00:00:41 --> 00:00:43 set for auction and the debate surrounding
00:00:43 --> 00:00:43 it.
00:00:44 --> 00:00:46 It's going to be an exciting journey, so
00:00:46 --> 00:00:49 let's get started. For the first
00:00:49 --> 00:00:52 time ever, astronomers have captured stunning
00:00:52 --> 00:00:54 visual evidence of a star's dramatic exit,
00:00:55 --> 00:00:57 a double detonation that marks its explosive
00:00:57 --> 00:01:00 death. This groundbreaking discovery
00:01:00 --> 00:01:02 centres around a type of stellar explosion
00:01:02 --> 00:01:05 known as a type 1a supernova, which plays an
00:01:05 --> 00:01:07 absolutely crucial role in our understanding
00:01:07 --> 00:01:10 of the universe. These specific supernovas
00:01:10 --> 00:01:13 are not just spectacular cosmic fireworks.
00:01:13 --> 00:01:15 They are vital for accurately measuring the
00:01:15 --> 00:01:18 universe's expansion rate, a topic currently
00:01:18 --> 00:01:20 at the heart of a major cosmological debate.
00:01:21 --> 00:01:23 What's more, type 1A supernovas are also the
00:01:23 --> 00:01:25 primary source of iron found throughout the
00:01:25 --> 00:01:28 cosmos, making their explosion mechanisms a
00:01:28 --> 00:01:31 puzzle astronomers are keen to solve. The
00:01:31 --> 00:01:33 evidence for this twin eruption was found by
00:01:33 --> 00:01:35 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 --> 00:01:42 which is the remnant of a star that met its
00:01:42 --> 00:01:44 explosive end centuries ago. While
00:01:44 --> 00:01:46 astronomers have long theorised that white
00:01:46 --> 00:01:48 dwarfs, the dense husks of dead stars,
00:01:49 --> 00:01:51 typically explode after steadily accumulating
00:01:51 --> 00:01:53 material from a companion star until they
00:01:53 --> 00:01:55 reach a critical mass known as the
00:01:55 --> 00:01:57 Chandrasekhar limit. Hints have suggested
00:01:57 --> 00:02:00 other mechanisms might be at play. Using the
00:02:00 --> 00:02:02 European Southern Observatory's Very Large
00:02:02 --> 00:02:05 Telescope, researchers found those two
00:02:05 --> 00:02:07 distinct calcium rings, which offer clear
00:02:07 --> 00:02:09 proof that white dwarfs can indeed detonate
00:02:09 --> 00:02:11 well before reaching the Chandrasekhar mass
00:02:11 --> 00:02:14 limit. This confirms the existence of the
00:02:14 --> 00:02:17 double detonation mechanism in nature. The
00:02:17 --> 00:02:20 proposed scenario is fascinating. The white
00:02:20 --> 00:02:22 dwarf first blankets itself in stolen helium
00:02:22 --> 00:02:25 from its neighbour. This helium then ignites,
00:02:26 --> 00:02:28 sending a shockwave inward that causes the
00:02:28 --> 00:02:30 dead star's core to ignite in a second, much
00:02:30 --> 00:02:33 larger explosion. Studying these dual
00:02:33 --> 00:02:35 detonations has profound implications,
00:02:36 --> 00:02:38 particularly for how we use type 1A
00:02:38 --> 00:02:40 supernovas as standard candles,
00:02:40 --> 00:02:42 cosmic benchmarks that explode with
00:02:42 --> 00:02:44 consistent Brightness, allowing astronomers
00:02:44 --> 00:02:47 to measure vast distances and calculate the
00:02:47 --> 00:02:49 universe's expansion rate. This tangible
00:02:49 --> 00:02:51 evidence not only helps solve a ah, long
00:02:51 --> 00:02:54 standing mystery, but also offers a truly
00:02:54 --> 00:02:57 visual spectacle revealing the inner workings
00:02:57 --> 00:02:59 of such a dramatic cosmic event.
00:03:00 --> 00:03:03 Moving on, let's head over to Mars. Imagine
00:03:03 --> 00:03:05 building a home on Mars that literally grows
00:03:05 --> 00:03:07 itself. It sounds like something out of
00:03:07 --> 00:03:09 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
00:03:14 --> 00:03:16 green algae. This innovation could be a game
00:03:16 --> 00:03:19 changer for human missions to other worlds,
00:03:19 --> 00:03:21 tackling the immense challenge and cost of
00:03:21 --> 00:03:23 transporting building materials from Earth.
00:03:24 --> 00:03:26 The concept is elegantly simple. If a
00:03:26 --> 00:03:28 habitat is constructed from this bioplastic
00:03:28 --> 00:03:30 and it can grow algae within its structure,
00:03:31 --> 00:03:32 that algae can then produce even more
00:03:32 --> 00:03:35 bioplastic. This creates a self sustaining
00:03:35 --> 00:03:37 closed loop system that could allow
00:03:37 --> 00:03:39 extraterrestrial settlements to not only
00:03:39 --> 00:03:41 sustain themselves, but also expand over
00:03:41 --> 00:03:44 time. It truly echoes the living
00:03:44 --> 00:03:47 ships seen in sci fi classics like Stargate
00:03:47 --> 00:03:49 Atlantis or Star Trek. In lab
00:03:49 --> 00:03:51 experiments, researchers successfully
00:03:51 --> 00:03:53 recreated the challenging atmospheric
00:03:53 --> 00:03:56 conditions of Mars, where the air pressure is
00:03:56 --> 00:03:58 significantly lower and the atmosphere is
00:03:58 --> 00:04:01 rich in carbon dioxide. Despite these
00:04:01 --> 00:04:04 harsh conditions, a common green algae called
00:04:04 --> 00:04:06 Dunaliella tertiolecta thrived inside
00:04:06 --> 00:04:09 a 3D printed growth chamber made from this
00:04:09 --> 00:04:11 new bioplastic, which is a type of
00:04:11 --> 00:04:14 polylactic acid. The bioplastic
00:04:14 --> 00:04:17 material proved crucial, blocking harmful UV
00:04:17 --> 00:04:19 radiation while still allowing enough light
00:04:19 --> 00:04:22 to penetrate for photosynthesis. Critically,
00:04:22 --> 00:04:24 the chamber also created a pressure gradient
00:04:24 --> 00:04:26 that allowed liquid water to stabilise within
00:04:26 --> 00:04:29 its walls, a key element for life that is
00:04:29 --> 00:04:31 otherwise unstable on the Martian surface.
00:04:32 --> 00:04:34 This research indicates that even on
00:04:34 --> 00:04:36 seemingly barren worlds, organic growth could
00:04:36 --> 00:04:38 be harnessed to construct human habitats.
00:04:39 --> 00:04:41 This builds upon previous work by the same
00:04:41 --> 00:04:43 team, which showed that sheets of silica
00:04:43 --> 00:04:46 aerogels could mimic Earth's greenhouse
00:04:46 --> 00:04:48 effect to enable biological growth on other
00:04:48 --> 00:04:50 planets. Combining these two lines of
00:04:50 --> 00:04:53 research could pave the way for a truly
00:04:53 --> 00:04:56 sustainable human presence beyond Earth. The
00:04:56 --> 00:04:58 next step for the team is to demonstrate that
00:04:58 --> 00:05:00 these bioplastic habitats can be grown in a
00:05:00 --> 00:05:03 vacuum, simulating conditions for missions
00:05:03 --> 00:05:06 to other deep space locations like the Moon.
00:05:07 --> 00:05:09 Beyond the exciting prospects for space
00:05:09 --> 00:05:11 exploration, this kind of biomaterial
00:05:11 --> 00:05:13 technology is expected to have significant
00:05:14 --> 00:05:16 spin off benefits for sustainability here on
00:05:16 --> 00:05:18 Earth, offering innovative solutions for our
00:05:18 --> 00:05:19 own planet's future.
00:05:20 --> 00:05:22 Okay, let's make a quick trip back to Earth.
00:05:23 --> 00:05:25 For skywatchers across most of the US and
00:05:25 --> 00:05:27 southern Canada, and indeed for many in North
00:05:27 --> 00:05:30 America and Europe, there's a fantastic
00:05:30 --> 00:05:32 opportunity this week to witness two of
00:05:32 --> 00:05:34 humanity's largest orbiting outposts within
00:05:34 --> 00:05:37 minutes of each other. I'm talking about the
00:05:37 --> 00:05:39 International Space Station or iss, and
00:05:39 --> 00:05:42 China's Tiangong Space Station. If you're up
00:05:42 --> 00:05:44 during the pre dawn hours, you might even
00:05:44 --> 00:05:47 catch both in the sky at the same time on
00:05:47 --> 00:05:50 certain mornings. It's truly remarkable how
00:05:50 --> 00:05:52 many satellites now orbit Earth, though. Most
00:05:52 --> 00:05:55 of the over 30 objects are space
00:05:55 --> 00:05:58 junk, too small to see with the unaided eye.
00:05:58 --> 00:06:00 But there are about 500 that are large enough
00:06:00 --> 00:06:03 and low enough in orbit to be visible. As the
00:06:03 --> 00:06:06 distinguished British scientist Desmond King
00:06:06 --> 00:06:08 Healy once put it, a satellite looks like a
00:06:08 --> 00:06:10 star that has taken leave of its senses and
00:06:10 --> 00:06:12 decided to move off to another part of the
00:06:12 --> 00:06:15 sky. The International Space
00:06:15 --> 00:06:17 Station is by far the biggest and brightest
00:06:17 --> 00:06:19 of these man made objects. Imagine
00:06:19 --> 00:06:21 something almost the length of a football
00:06:21 --> 00:06:24 field, including the end zones. Powered
00:06:24 --> 00:06:26 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 --> 00:06:47 can appear up to two and a half times
00:06:47 --> 00:06:50 brighter than Venus and sometimes even flare
00:06:50 --> 00:06:52 to an incredible magnitude, making it much
00:06:52 --> 00:06:55 brighter than any star. Then there's
00:06:55 --> 00:06:57 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
00:07:06 --> 00:07:08 slightly lower altitude of about 393
00:07:08 --> 00:07:11 kilometres and can appear as bright as Venus
00:07:11 --> 00:07:14 or Jupiter on its most favourable passes.
00:07:14 --> 00:07:17 Currently, between the ISS and Tiangong,
00:07:18 --> 00:07:20 there are 14 humans living and working in
00:07:20 --> 00:07:23 space. Now, if you're wondering when and
00:07:23 --> 00:07:25 where to look, it's easier than you might
00:07:25 --> 00:07:27 think. From now through the end of July,
00:07:28 --> 00:07:30 North Americans and Europeans will have
00:07:30 --> 00:07:32 numerous chances to spot both stations,
00:07:33 --> 00:07:35 primarily because nights are shorter,
00:07:35 --> 00:07:37 allowing these low Earth orbit satellites to
00:07:37 --> 00:07:40 remain illuminated by the sun for longer
00:07:40 --> 00:07:43 periods. Since both stations circle
00:07:43 --> 00:07:45 earth roughly every 90 minutes, you might
00:07:45 --> 00:07:47 even catch them on several consecutive
00:07:47 --> 00:07:50 passes. They have slightly different orbital
00:07:50 --> 00:07:52 altitudes and inclinations, which makes
00:07:52 --> 00:07:54 seeing them simultaneously a less common
00:07:54 --> 00:07:57 event. But it is possible to find out the
00:07:57 --> 00:07:59 exact viewing schedule for your specific
00:07:59 --> 00:08:02 location. I highly recommend visiting either
00:08:02 --> 00:08:04 Chris Peet's Heavens above website or NASA's
00:08:04 --> 00:08:07 spot the station. Both are excellent
00:08:07 --> 00:08:09 resources. Heavens above allows you to input
00:08:09 --> 00:08:11 your precise latitude and longitude to
00:08:11 --> 00:08:13 generate accurate sighting data for both the
00:08:13 --> 00:08:16 ISS and Tiangong. NASA's
00:08:16 --> 00:08:19 Spot the Station offers a widget where you
00:08:19 --> 00:08:21 simply enter your location and it provides
00:08:21 --> 00:08:23 details like the time of the flyover, how
00:08:23 --> 00:08:26 long it will be visible, its maximum height
00:08:26 --> 00:08:28 in the sky, and the direction it will appear
00:08:28 --> 00:08:31 and disappear from your view. Just remember
00:08:31 --> 00:08:33 that predictions can change slightly due to
00:08:33 --> 00:08:35 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 --> 00:08:41 Next up, let's talk about an old, yet
00:08:41 --> 00:08:43 mysterious dark energy
00:08:44 --> 00:08:46 for generations, humanity has looked up at
00:08:46 --> 00:08:48 the stars and pondered the ultimate fate of
00:08:48 --> 00:08:51 our universe. Will it expand forever into the
00:08:51 --> 00:08:53 cold, empty vastness, or is there a more
00:08:53 --> 00:08:56 dramatic end in store? A new study published
00:08:56 --> 00:08:58 by physicists from Cornell University,
00:08:58 --> 00:09:00 Shanghai, Jiao Tong University, and other
00:09:00 --> 00:09:03 institutions suggests we might finally have a
00:09:03 --> 00:09:06 surprising and specific answer. Using data
00:09:06 --> 00:09:08 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 --> 00:09:15 developed a model that predicts our universe
00:09:16 --> 00:09:18 will meet its end in a big crunch in
00:09:18 --> 00:09:21 approximately 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
00:09:33 --> 00:09:35 assumption that the universe will expand
00:09:35 --> 00:09:38 indefinitely. Instead, it suggests that after
00:09:38 --> 00:09:41 reaching its maximum expansion in about 7
00:09:41 --> 00:09:43 billion years, the universe will begin to
00:09:43 --> 00:09:45 contract until everything eventually
00:09:45 --> 00:09:48 collapses back into a single point. The key
00:09:48 --> 00:09:50 to this theory lies in understanding dark
00:09:50 --> 00:09:52 energy, the mysterious force that makes up
00:09:52 --> 00:09:55 about 70% of the universe and drives its
00:09:55 --> 00:09:58 expansion. For a long time, it was assumed
00:09:58 --> 00:10:00 that dark energy behaved like a cosmological
00:10:00 --> 00:10:03 constant, maintaining a steady pressure that
00:10:03 --> 00:10:05 pushed space apart indefinitely. However,
00:10:05 --> 00:10:08 recent observations hint that dark energy
00:10:08 --> 00:10:11 might actually be dynamic. The researchers
00:10:11 --> 00:10:13 propose a model involving an ultralight
00:10:13 --> 00:10:15 particle called an axion, combined with
00:10:15 --> 00:10:17 what's known as a negative cosmological
00:10:17 --> 00:10:20 constant. You can think of it like a massive
00:10:20 --> 00:10:22 rubber band. Initially, the universe expands
00:10:22 --> 00:10:25 as this rubber band stretches, but eventually
00:10:25 --> 00:10:27 the elastic force becomes stronger than the
00:10:27 --> 00:10:30 expansion, causing everything to snap back
00:10:30 --> 00:10:33 together. According to this new model, the
00:10:33 --> 00:10:35 universe will continue expanding, but at a
00:10:35 --> 00:10:38 gradually slowing rate until it reaches its
00:10:38 --> 00:10:40 maximum size, about 69%
00:10:40 --> 00:10:43 larger than today in roughly 7 billion
00:10:43 --> 00:10:46 years. Then gradual contraction
00:10:46 --> 00:10:49 will begin as gravitational forces and
00:10:49 --> 00:10:52 the negative cosmological constant take over,
00:10:52 --> 00:10:54 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 --> 00:10:58 prediction comes with significant
00:10:58 --> 00:11:01 uncertainty. The researchers acknowledge
00:11:01 --> 00:11:03 that their model has large margins of error
00:11:04 --> 00:11:06 due to limited observational data, and the
00:11:06 --> 00:11:09 negative cosmological constant that drives
00:11:09 --> 00:11:11 their prediction remains highly speculative.
00:11:11 --> 00:11:14 Alternative scenarios, including eternal
00:11:14 --> 00:11:16 expansion, are still very much on the table.
00:11:17 --> 00:11:19 What makes this research particularly
00:11:19 --> 00:11:22 exciting is isn't just the prediction itself,
00:11:22 --> 00:11:25 but the fact that we may soon be able to test
00:11:25 --> 00:11:28 it. Several m major astronomical
00:11:28 --> 00:11:30 projects Launching in the coming years are
00:11:30 --> 00:11:33 set to provide much more precise measurements
00:11:33 --> 00:11:36 of dark energy's behaviour. These future
00:11:36 --> 00:11:38 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
00:11:47 --> 00:11:49 countdown hardly constitutes an immediate
00:11:49 --> 00:11:51 crisis for us. To put it in perspective,
00:11:51 --> 00:11:54 complex life on Earth has only existed for
00:11:54 --> 00:11:56 about 600 million years. 20 billion
00:11:56 --> 00:11:59 years represents a time frame so vast that
00:11:59 --> 00:12:01 our sun will have died and our galaxy will
00:12:01 --> 00:12:04 have collided with Andromeda long before any
00:12:04 --> 00:12:05 cosmic collapse even begins.
00:12:06 --> 00:12:08 Nevertheless, this research represents a
00:12:08 --> 00:12:10 remarkable achievement in our understanding
00:12:10 --> 00:12:13 of the cosmos, providing us with a concrete
00:12:13 --> 00:12:15 timeline for what could be the most dramatic
00:12:15 --> 00:12:17 event possible. The end of the universe
00:12:17 --> 00:12:18 itself.
00:12:19 --> 00:12:22 Shifting gears from the vast cosmic scale to
00:12:22 --> 00:12:24 something a little closer to home, or at
00:12:24 --> 00:12:26 least closer to Earth, we have a fascinating
00:12:26 --> 00:12:29 story about a very special rock. The most
00:12:29 --> 00:12:31 massive piece of Mars ever found here on
00:12:31 --> 00:12:33 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
00:12:53 --> 00:12:55 found in mali back in 2021.
00:12:56 --> 00:12:58 This massive chunk of Mars was discovered by
00:12:58 --> 00:13:01 a meteorite hunter in November
00:13:01 --> 00:13:04 2023 in the sparsely populated
00:13:04 --> 00:13:07 Agadez region of Niger, an area more
00:13:07 --> 00:13:09 renowned for its dinosaur fossils than its
00:13:09 --> 00:13:12 meteorites. The Shanghai Astronomy
00:13:12 --> 00:13:14 Museum confirmed the rock's Martian identity
00:13:15 --> 00:13:17 after a small sample was sent there. And now
00:13:17 --> 00:13:19 this interplanetary treasure has a
00:13:19 --> 00:13:21 significant price tag. According to the
00:13:21 --> 00:13:24 Sotheby's listing, the meteorite shows
00:13:24 --> 00:13:26 minimal terrestrial weathering, which means
00:13:26 --> 00:13:29 its physical and chemical makeup haven't been
00:13:29 --> 00:13:31 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 --> 00:13:38 is likely a relatively recent arrival on
00:13:38 --> 00:13:41 Earth, having fallen from outer space not too
00:13:41 --> 00:13:44 long ago. Its characteristics tell us a
00:13:44 --> 00:13:46 lot about its journey. Based on a high
00:13:46 --> 00:13:48 percentage of a glass called maskelynite,
00:13:48 --> 00:13:50 along with some shock melted areas,
00:13:51 --> 00:13:53 scientists believe this rock was likely sent
00:13:53 --> 00:13:55 hurtling through space when a severe asteroid
00:13:55 --> 00:13:58 crashed into Mars. The Sotheby's listing
00:13:58 --> 00:14:00 further explains that the meteorite was
00:14:00 --> 00:14:03 formed from the slow cooling of Martian magma
00:14:03 --> 00:14:06 and and is characterised by a coarse grained
00:14:06 --> 00:14:09 texture, primarily composed of pyroxene,
00:14:09 --> 00:14:11 masculinite and olivine.
00:14:12 --> 00:14:15 However, the sale of such a rare specimen has
00:14:15 --> 00:14:17 sparked a debate among some scientists.
00:14:17 --> 00:14:20 Palaeontologist Steve Brusot from the
00:14:20 --> 00:14:22 University of Edinburgh expressed concern to
00:14:22 --> 00:14:25 CNN stating that it would be a shame if it
00:14:25 --> 00:14:27 disappeared into the vault of an oligarch,
00:14:27 --> 00:14:30 suggesting it belongs in a museum where it
00:14:30 --> 00:14:33 can be studied and enjoyed by the public. On
00:14:33 --> 00:14:35 the other hand, planetary scientist Julia
00:14:35 --> 00:14:37 Cartwright from the University of Leicester
00:14:37 --> 00:14:40 offered a different perspective, telling CNN
00:14:40 --> 00:14:43 that the scientific interest will remain and
00:14:43 --> 00:14:45 the new owner may be very interested in
00:14:45 --> 00:14:47 learning from it, meaning we could still
00:14:47 --> 00:14:49 gather a lot of science from this unique
00:14:49 --> 00:14:52 find. The Sotheby's auction is scheduled to
00:14:52 --> 00:14:53 begin on July 16th.
00:14:55 --> 00:14:57 That brings us to the end of another
