00:00:00 --> 00:00:00 [Music]
00:00:00 --> 00:00:02 Welcome to Astronomy Daily, your window
00:00:02 --> 00:00:04 to the universe, where we bring you the
00:00:04 --> 00:00:05 freshest discoveries and developments
00:00:05 --> 00:00:08 from across the cosmos. I'm Anna, and
00:00:08 --> 00:00:09 I'm thrilled to guide you through
00:00:10 --> 00:00:11 today's fascinating journey through
00:00:11 --> 00:00:14 space. In today's episode, we'll explore
00:00:14 --> 00:00:17 a remarkable observation of a black hole
00:00:17 --> 00:00:19 violently expelling matter at incredible
00:00:19 --> 00:00:22 speeds into deep space. We'll also cover
00:00:22 --> 00:00:24 SpaceX's impressive launch milestones
00:00:24 --> 00:00:26 and the global surge in space activities
00:00:26 --> 00:00:28 happening around the world. Plus, we'll
00:00:28 --> 00:00:30 discuss the historic inauguration of the
00:00:30 --> 00:00:32 African Space Agency and what it means
00:00:32 --> 00:00:35 for the continent's space ambitions. And
00:00:35 --> 00:00:37 finally, we'll venture to our moon,
00:00:37 --> 00:00:39 where a massive ancient crater may hold
00:00:40 --> 00:00:41 secrets about our lunar companion's
00:00:41 --> 00:00:44 fiery birth. So, settle in as we blast
00:00:44 --> 00:00:46 off into another edition of Astronomical
00:00:46 --> 00:00:49 Wonders and Cosmic Revelations.
00:00:50 --> 00:00:52 In a stunning discovery that challenges
00:00:52 --> 00:00:53 our understanding of these cosmic
00:00:53 --> 00:00:56 monsters, scientists have captured a
00:00:56 --> 00:00:58 black hole in the act of hurling matter
00:00:58 --> 00:01:00 into deep space at astonishing
00:01:00 --> 00:01:03 velocities. The culprit is located in
00:01:03 --> 00:01:05 NGC
00:01:05 --> 00:01:08 4, a beautiful spiral galaxy sitting
00:01:08 --> 00:01:09 over 12 million lighty years away in the
00:01:09 --> 00:01:12 constellation Centurus.
00:01:12 --> 00:01:13 While NGC
00:01:13 --> 00:01:16 4945 might appear serene from a
00:01:16 --> 00:01:18 distance, it harbors a ferocious secret
00:01:18 --> 00:01:21 at its core. Unlike some black holes
00:01:21 --> 00:01:23 that quietly consume their cosmic meals,
00:01:23 --> 00:01:25 such as the relatively calm one at the
00:01:25 --> 00:01:27 center of our own Milky Way, this super
00:01:27 --> 00:01:30 massive beast is both a voracious eater
00:01:30 --> 00:01:32 and a violent expeller. Using the
00:01:32 --> 00:01:34 advanced MUSE instrument on the European
00:01:34 --> 00:01:36 Southern Observatory's Very Large
00:01:36 --> 00:01:38 Telescope, astronomers have documented
00:01:38 --> 00:01:40 this black hole not only devouring
00:01:40 --> 00:01:42 surrounding material, but also
00:01:42 --> 00:01:45 generating powerful cone-shaped winds of
00:01:45 --> 00:01:47 gas and dust that blast outward with
00:01:47 --> 00:01:49 tremendous force. What's particularly
00:01:49 --> 00:01:51 fascinating is that these outflows,
00:01:51 --> 00:01:53 visible as striking red plumes against
00:01:53 --> 00:01:56 the galaxy's elegant spiral structure,
00:01:56 --> 00:01:58 are moving so rapidly that scientists
00:01:58 --> 00:02:00 expect them to completely escape the
00:02:00 --> 00:02:03 galaxy's gravitational pole. This matter
00:02:03 --> 00:02:05 will eventually drift into the vast
00:02:05 --> 00:02:07 emptiness of intergalactic space, a
00:02:07 --> 00:02:10 cosmic ejection on a truly enormous
00:02:10 --> 00:02:13 scale. This observation is reshaping our
00:02:13 --> 00:02:15 understanding of galactic dynamics.
00:02:15 --> 00:02:17 Black holes have long been known to pull
00:02:17 --> 00:02:19 matter inward with their immense
00:02:19 --> 00:02:21 gravity. But this dramatic example of
00:02:21 --> 00:02:24 matter ejection shows how these cosmic
00:02:24 --> 00:02:26 entities play a much more complex role
00:02:26 --> 00:02:29 in shaping their galactic neighborhoods.
00:02:29 --> 00:02:31 The expelled material which would
00:02:31 --> 00:02:32 otherwise be available for star
00:02:32 --> 00:02:35 formation is essentially being removed
00:02:35 --> 00:02:37 from the galaxy's inventory. This
00:02:37 --> 00:02:39 finding represents a pivotal moment in
00:02:39 --> 00:02:41 our quest to understand the intricate
00:02:41 --> 00:02:44 relationship between super massive black
00:02:44 --> 00:02:46 holes and the evolution of their host
00:02:46 --> 00:02:49 galaxies across cosmic time. What makes
00:02:49 --> 00:02:52 this discovery truly revolutionary is
00:02:52 --> 00:02:53 that these black hole-driven winds
00:02:54 --> 00:02:56 behave in ways astronomers didn't
00:02:56 --> 00:02:58 anticipate. The MUSE data reveal
00:02:58 --> 00:03:00 something counterintuitive.
00:03:00 --> 00:03:02 Instead of gradually slowing down as
00:03:02 --> 00:03:04 they travel outward through the galaxy,
00:03:04 --> 00:03:06 these powerful outflows actually
00:03:06 --> 00:03:07 accelerate as they move away from the
00:03:07 --> 00:03:10 galactic center. They gain momentum on
00:03:10 --> 00:03:11 their journey toward the edge of the
00:03:11 --> 00:03:14 galaxy and eventually into intergalactic
00:03:14 --> 00:03:17 space. This acceleration mechanism is
00:03:17 --> 00:03:18 particularly significant for
00:03:18 --> 00:03:21 understanding galactic evolution. By
00:03:21 --> 00:03:23 forcefully ejecting potential star
00:03:23 --> 00:03:25 forming material from the galaxy, these
00:03:25 --> 00:03:27 black holes effectively act as cosmic
00:03:27 --> 00:03:29 regulators, controlling the rate at
00:03:29 --> 00:03:31 which new stars can form within their
00:03:32 --> 00:03:34 host galaxies. It's a form of
00:03:34 --> 00:03:36 self-regulation that dampens stellar
00:03:36 --> 00:03:38 birth rates across the entire galactic
00:03:38 --> 00:03:41 structure. Even more fascinating is how
00:03:41 --> 00:03:43 this process creates a feedback loop
00:03:43 --> 00:03:46 that affects the black hole itself. By
00:03:46 --> 00:03:48 removing the very gas and dust they feed
00:03:48 --> 00:03:50 upon, more active and powerful black
00:03:50 --> 00:03:54 holes actually impede their own growth.
00:03:54 --> 00:03:56 This self-limiting behavior drives the
00:03:56 --> 00:03:58 whole system toward a kind of galactic
00:03:58 --> 00:04:01 equilibrium, a delicate balance between
00:04:01 --> 00:04:03 consumption and ejection. The new
00:04:04 --> 00:04:05 findings represent a significant step
00:04:05 --> 00:04:07 forward in our understanding of how
00:04:07 --> 00:04:10 galaxies evolve over cosmic time. These
00:04:10 --> 00:04:11 accelerating winds appear to be a key
00:04:11 --> 00:04:13 mechanism through which black holes
00:04:14 --> 00:04:15 shape not just their immediate
00:04:15 --> 00:04:17 surroundings but the fate of entire
00:04:17 --> 00:04:20 galaxies. By regulating both star
00:04:20 --> 00:04:21 formation and their own feeding
00:04:22 --> 00:04:24 processes, these cosmic behemoths play a
00:04:24 --> 00:04:26 far more sophisticated role in universal
00:04:26 --> 00:04:29 dynamics than previously understood.
00:04:30 --> 00:04:31 Scientists believe that by studying
00:04:31 --> 00:04:34 these acceleration patterns in detail,
00:04:34 --> 00:04:36 we can better comprehend the forces that
00:04:36 --> 00:04:37 have shaped galactic evolution
00:04:37 --> 00:04:40 throughout the universe's history. One
00:04:40 --> 00:04:43 of the fundamental questions in modern
00:04:43 --> 00:04:46 astrophysics. Let's move on now and take
00:04:46 --> 00:04:47 a look at this week's launch schedule.
00:04:48 --> 00:04:49 SpaceX continues to push the boundaries
00:04:49 --> 00:04:51 of what's possible in the commercial
00:04:51 --> 00:04:53 space industry, setting remarkable
00:04:53 --> 00:04:54 records that would have seemed
00:04:54 --> 00:04:56 impossible just a few years ago. The
00:04:56 --> 00:04:59 company is on track to achieve its 250th
00:04:59 --> 00:05:01 mission launch from Space Launch Complex
00:05:01 --> 00:05:03 40 in Florida this week, a milestone
00:05:03 --> 00:05:05 that highlights just how quickly SpaceX
00:05:05 --> 00:05:08 has transformed access to space. The
00:05:08 --> 00:05:10 pace of launches is nothing short of
00:05:10 --> 00:05:12 extraordinary. SpaceX has now surpassed
00:05:12 --> 00:05:15 250 dedicated Starlink launches, rapidly
00:05:16 --> 00:05:17 expanding its satellite internet
00:05:17 --> 00:05:19 constellation to provide global
00:05:19 --> 00:05:21 coverage. Just last week, the company
00:05:21 --> 00:05:23 deployed a record 29 Starlink satellites
00:05:23 --> 00:05:26 in a single mission, demonstrating their
00:05:26 --> 00:05:28 ability to maximize payload capacity on
00:05:28 --> 00:05:32 their workhorse, Falcon 9 rocket. This
00:05:32 --> 00:05:33 achievement is particularly noteworthy
00:05:33 --> 00:05:36 because it also marked SpaceX's 50th
00:05:36 --> 00:05:38 mission of 2025, maintaining a launch
00:05:38 --> 00:05:40 cadence that averages nearly three
00:05:40 --> 00:05:42 launches per week. If this pace
00:05:42 --> 00:05:44 continues, the company is on track to
00:05:44 --> 00:05:46 potentially exceed 100 launches this
00:05:46 --> 00:05:49 year, a figure that the entire global
00:05:49 --> 00:05:51 launch industry struggled to achieve
00:05:51 --> 00:05:54 collectively just a decade ago. Perhaps
00:05:54 --> 00:05:57 equally impressive is SpaceX's growing
00:05:57 --> 00:06:00 mastery of reusability. The same mission
00:06:00 --> 00:06:02 marked the 100th consecutive successful
00:06:02 --> 00:06:04 Falcon 9 landing since their last
00:06:04 --> 00:06:06 landing failure. This perfect landing
00:06:06 --> 00:06:08 streak highlights the maturity of
00:06:08 --> 00:06:10 SpaceX's recovery technology and
00:06:10 --> 00:06:11 operations.
00:06:12 --> 00:06:13 The booster used for this mission,
00:06:13 --> 00:06:16 designated
00:06:16 --> 00:06:18 B78, became the ninth in the fleet to
00:06:18 --> 00:06:21 reach 20 flights, demonstrating the
00:06:21 --> 00:06:23 durability and reliability of these
00:06:23 --> 00:06:25 vehicles that were initially designed
00:06:25 --> 00:06:27 for just a handful of missions. The
00:06:27 --> 00:06:29 economics of this reusability revolution
00:06:30 --> 00:06:32 cannot be overstated. By recovering and
00:06:32 --> 00:06:34 refurbishing first stage boosters,
00:06:34 --> 00:06:36 SpaceX has dramatically reduced launch
00:06:36 --> 00:06:39 costs while simultaneously increasing
00:06:39 --> 00:06:41 their launch capacity. What once
00:06:41 --> 00:06:43 required building dozens of new rockets
00:06:43 --> 00:06:45 annually can now be accomplished with a
00:06:45 --> 00:06:47 much smaller fleet of frequently flown
00:06:47 --> 00:06:49 vehicles, this unprecedented launch
00:06:49 --> 00:06:52 cadence is enabling SpaceX to deploy its
00:06:52 --> 00:06:54 Starlink constellation at a pace that
00:06:54 --> 00:06:56 competitors struggle to match. With each
00:06:56 --> 00:06:58 launch carrying dozens of satellites,
00:06:58 --> 00:07:00 the company is rapidly approaching the
00:07:00 --> 00:07:01 point where it can offer true global
00:07:01 --> 00:07:03 coverage for its internet service,
00:07:04 --> 00:07:05 including in remote and underserved
00:07:05 --> 00:07:07 regions where traditional internet
00:07:07 --> 00:07:09 infrastructure is impractical.
00:07:09 --> 00:07:11 While SpaceX dominates headlines with
00:07:11 --> 00:07:14 its impressive launch schedule, it's
00:07:14 --> 00:07:15 worth noting that they're not the only
00:07:15 --> 00:07:17 players in this increasingly busy
00:07:17 --> 00:07:20 orbital traffic pattern. Other space
00:07:20 --> 00:07:22 fairing nations continue to maintain
00:07:22 --> 00:07:25 active launch schedules with China being
00:07:25 --> 00:07:27 particularly noteworthy among them. In
00:07:27 --> 00:07:29 fact, China attempted to launch one of
00:07:29 --> 00:07:32 its Chang Jang 12A rockets earlier this
00:07:32 --> 00:07:34 week, though the mission was scrubbed
00:07:34 --> 00:07:36 for reasons that haven't been officially
00:07:36 --> 00:07:38 disclosed. This particular rocket was
00:07:38 --> 00:07:40 set to carry the fourth batch of Shing
00:07:40 --> 00:07:43 Wuang satellites for the Guawang
00:07:43 --> 00:07:46 network, one of two mega constellations
00:07:46 --> 00:07:48 China is developing to compete with
00:07:48 --> 00:07:49 Starlink in the global satellite
00:07:49 --> 00:07:53 internet market. April 2025 has now
00:07:53 --> 00:07:55 secured its place in the record books as
00:07:55 --> 00:07:58 the busiest April in spaceflight history
00:07:58 --> 00:08:00 with an impressive 26 rockets launching
00:08:00 --> 00:08:03 worldwide. This remarkable achievement
00:08:03 --> 00:08:05 reflects the growing commercialization
00:08:05 --> 00:08:07 and accessibility of space launch
00:08:07 --> 00:08:09 capabilities across multiple countries
00:08:10 --> 00:08:12 and private companies. Even more
00:08:12 --> 00:08:14 impressive was the flurry of activity
00:08:14 --> 00:08:16 that occurred at the end of the month.
00:08:16 --> 00:08:19 Between April 28th and 29th, a new
00:08:19 --> 00:08:21 global launch record was set when six
00:08:21 --> 00:08:23 different rockets blasted off within
00:08:24 --> 00:08:26 just 18 hours of each other. This
00:08:26 --> 00:08:28 unprecedented concentration of launches
00:08:28 --> 00:08:30 required careful coordination among
00:08:30 --> 00:08:32 various launch providers and space
00:08:32 --> 00:08:34 traffic management authorities to ensure
00:08:34 --> 00:08:35 safe
00:08:35 --> 00:08:38 operations. This accelerating pace of
00:08:38 --> 00:08:39 launches is expected to continue
00:08:39 --> 00:08:41 throughout May and beyond with
00:08:41 --> 00:08:44 additional Starlink missions, crude
00:08:44 --> 00:08:46 launches to space stations, and various
00:08:46 --> 00:08:48 satellite deployments already on the
00:08:48 --> 00:08:49 manifest.
00:08:49 --> 00:08:51 We're witnessing a historic
00:08:51 --> 00:08:52 transformation in how frequently
00:08:52 --> 00:08:54 humanity accesses space, and the trend
00:08:54 --> 00:08:57 shows no signs of slowing down. The
00:08:57 --> 00:08:58 space industry's rapid growth presents
00:08:58 --> 00:09:01 both opportunities and challenges. While
00:09:01 --> 00:09:02 increased launch cadence means more
00:09:02 --> 00:09:05 satellites for communications, Earth
00:09:05 --> 00:09:08 observation, and scientific research, it
00:09:08 --> 00:09:09 also creates concerns about orbital
00:09:09 --> 00:09:12 congestion, and space debris management.
00:09:12 --> 00:09:14 International cooperation on space
00:09:14 --> 00:09:16 traffic management is becoming
00:09:16 --> 00:09:18 increasingly crucial as more rockets and
00:09:18 --> 00:09:20 satellites fill the
00:09:20 --> 00:09:23 skies. And another new player has just
00:09:23 --> 00:09:25 run onto the playing field. On April
00:09:25 --> 00:09:28 20th, 2025, a significant milestone in
00:09:28 --> 00:09:30 African space exploration was achieved
00:09:30 --> 00:09:32 with the formal inauguration of the
00:09:32 --> 00:09:36 African Space Agency or AFSA in Cairo,
00:09:36 --> 00:09:38 Egypt. This development marks nearly a
00:09:38 --> 00:09:40 decade of coordinated planning since
00:09:40 --> 00:09:43 2016 when the African Union first
00:09:43 --> 00:09:45 adopted the comprehensive African space
00:09:45 --> 00:09:47 policy and strategy framework. The
00:09:47 --> 00:09:50 creation of AFSA represents a deliberate
00:09:50 --> 00:09:52 move to unite the continent's space
00:09:52 --> 00:09:55 ambitions under a single organizational
00:09:55 --> 00:09:58 umbrella. Currently, 22 African nations
00:09:58 --> 00:10:01 operate their own space agencies with
00:10:01 --> 00:10:03 varying degrees of legislative support
00:10:03 --> 00:10:05 and organizational structures. Some are
00:10:05 --> 00:10:07 fully independent agencies backed by
00:10:07 --> 00:10:09 national legislation, while others
00:10:10 --> 00:10:11 function as departments within broader
00:10:12 --> 00:10:12 research
00:10:12 --> 00:10:15 institutions. This new continental
00:10:15 --> 00:10:17 agency will serve as the coordinating
00:10:17 --> 00:10:18 body for Africa's existing space
00:10:18 --> 00:10:21 programs, streamlining cooperation
00:10:21 --> 00:10:23 between member states and creating a
00:10:24 --> 00:10:26 unified voice when engaging with
00:10:26 --> 00:10:28 international partners. Rather than
00:10:28 --> 00:10:31 replacing national agencies, AFSA will
00:10:31 --> 00:10:33 amplify their collective impact through
00:10:33 --> 00:10:36 strategic coordination. The AY's mandate
00:10:36 --> 00:10:38 includes establishing a centralized
00:10:38 --> 00:10:40 point of contact for negotiations with
00:10:40 --> 00:10:42 private launch providers, satellite
00:10:42 --> 00:10:44 manufacturers, and other space services
00:10:44 --> 00:10:47 companies. This unified approach gives
00:10:47 --> 00:10:48 African nations significantly more
00:10:48 --> 00:10:50 leverage in these discussions than they
00:10:50 --> 00:10:53 would have individually. Dr. Dr.
00:10:53 --> 00:10:55 Tidianara, president of the AFSA
00:10:55 --> 00:10:57 Council, emphasized at the launch
00:10:57 --> 00:10:59 ceremony that the agency will focus on
00:10:59 --> 00:11:01 practical applications that benefit
00:11:01 --> 00:11:04 African citizens, including improved
00:11:04 --> 00:11:06 agricultural forecasting, disaster
00:11:06 --> 00:11:08 monitoring, telecommunications
00:11:08 --> 00:11:10 infrastructure, and educational
00:11:10 --> 00:11:12 opportunities. Many African space
00:11:12 --> 00:11:14 agencies already specialize in Earth
00:11:14 --> 00:11:16 observation missions, tracking climate
00:11:16 --> 00:11:19 patterns crucial for agriculture and
00:11:19 --> 00:11:21 providing services like navigation
00:11:21 --> 00:11:23 systems and emergency response
00:11:23 --> 00:11:25 coordination. The South African National
00:11:25 --> 00:11:27 Space Agency, for example, has developed
00:11:27 --> 00:11:29 a successful satellite-based wildfire
00:11:29 --> 00:11:32 detection system that identifies remote
00:11:32 --> 00:11:34 blazes and alerts firefighting
00:11:34 --> 00:11:36 authorities through AFSA. These
00:11:36 --> 00:11:38 specialized capabilities can now be
00:11:38 --> 00:11:41 shared more effectively across borders,
00:11:41 --> 00:11:43 creating a multiplier effect that
00:11:43 --> 00:11:45 benefits all member states while
00:11:45 --> 00:11:47 avoiding costly duplication of efforts.
00:11:47 --> 00:11:49 The agency will also play a crucial role
00:11:49 --> 00:11:52 in standardizing regulations, protocols,
00:11:52 --> 00:11:53 and technological systems across the
00:11:54 --> 00:11:56 continent's space sector. Despite
00:11:56 --> 00:11:58 Africa's vast geographical footprint
00:11:58 --> 00:12:00 covering oneif of Earth's land surface,
00:12:00 --> 00:12:02 the continent currently contributes a
00:12:02 --> 00:12:03 mere
00:12:03 --> 00:12:06 0.5% to the global space budget. This
00:12:06 --> 00:12:08 stark disparity highlights the
00:12:08 --> 00:12:11 significant untapped potential within
00:12:11 --> 00:12:13 Africa's space sector. The newly
00:12:13 --> 00:12:16 established African Space Agency aims to
00:12:16 --> 00:12:18 fundamentally transform this reality,
00:12:18 --> 00:12:20 pivoting the continent from being
00:12:20 --> 00:12:22 primarily a consumer of space technology
00:12:22 --> 00:12:25 and data to becoming an active producer
00:12:25 --> 00:12:28 and innovator. As Dr. Uatara aptly
00:12:28 --> 00:12:31 described it, Africa is a sleeping giant
00:12:32 --> 00:12:34 in the space economy. With ambitious
00:12:34 --> 00:12:37 projections estimating space economy
00:12:37 --> 00:12:39 revenue reaching$22 billion by
00:12:39 --> 00:12:42 2026, the agency recognizes that current
00:12:42 --> 00:12:44 activities have only scratched the
00:12:44 --> 00:12:47 surface of what's possible. The focus
00:12:47 --> 00:12:49 now is on leveraging Africa's abundant
00:12:49 --> 00:12:52 natural resources alongside its growing
00:12:52 --> 00:12:54 pool of engineering talent to develop
00:12:54 --> 00:12:56 indigenous space capabilities rather
00:12:56 --> 00:12:59 than relying on imported solutions.
00:12:59 --> 00:13:01 Three key pillars form the foundation of
00:13:01 --> 00:13:04 AFSA's approach. Recognizing the
00:13:04 --> 00:13:06 necessity of space technologies for
00:13:06 --> 00:13:08 development, establishing robust
00:13:08 --> 00:13:10 structural frameworks to support growth,
00:13:10 --> 00:13:12 and positioning Africa advantageously
00:13:12 --> 00:13:14 within the emerging landscapes of new
00:13:14 --> 00:13:17 space and artificial intelligence.
00:13:17 --> 00:13:19 Infrastructure development stands as a
00:13:19 --> 00:13:21 critical priority with plans to both
00:13:21 --> 00:13:23 incorporate existing facilities and
00:13:23 --> 00:13:26 construct new ones across member states.
00:13:26 --> 00:13:28 This doesn't solely involve physical
00:13:28 --> 00:13:30 launch sites and satellite manufacturing
00:13:30 --> 00:13:32 capabilities, but also encompasses
00:13:32 --> 00:13:34 developing specialized educational
00:13:34 --> 00:13:36 programs and training opportunities to
00:13:36 --> 00:13:39 build a skilled workforce. The agency
00:13:39 --> 00:13:40 will emphasize educational initiatives
00:13:40 --> 00:13:42 at all levels from primary school
00:13:42 --> 00:13:44 programs that spark interest in space
00:13:44 --> 00:13:47 sciences to advanced university
00:13:47 --> 00:13:48 curricula that produce the next
00:13:48 --> 00:13:50 generation of African aerospace
00:13:50 --> 00:13:53 engineers, astrophysicists, and mission
00:13:53 --> 00:13:56 specialists. Creating this human capital
00:13:56 --> 00:13:58 pipeline is considered essential for
00:13:58 --> 00:14:00 sustainable growth in the sector.
00:14:00 --> 00:14:02 Resource coordination represents another
00:14:02 --> 00:14:05 major focus area. Given the substantial
00:14:05 --> 00:14:08 investment required for space programs,
00:14:08 --> 00:14:10 AFSA will facilitate resource sharing
00:14:10 --> 00:14:12 among member states, preventing costly
00:14:12 --> 00:14:14 duplication of efforts while maximizing
00:14:14 --> 00:14:17 the impact of available funding. This
00:14:17 --> 00:14:19 cooperative approach extends to sharing
00:14:19 --> 00:14:22 markets, technologies, and scientific
00:14:22 --> 00:14:24 outcomes. Through these coordinated
00:14:24 --> 00:14:27 efforts, Africa aims to claim its
00:14:27 --> 00:14:29 rightful place in the global space
00:14:29 --> 00:14:31 community, transforming from a minor
00:14:31 --> 00:14:33 player to a significant contributor in
00:14:33 --> 00:14:36 international space exploration and
00:14:36 --> 00:14:39 utilization. Let's change gears now.
00:14:40 --> 00:14:42 Approximately 4.3 billion years ago, a
00:14:42 --> 00:14:44 massive celestial body slammed into the
00:14:44 --> 00:14:47 lunar surface, creating what we now know
00:14:47 --> 00:14:50 as the South Pole Atkin Basin. This
00:14:50 --> 00:14:52 colossal impact crater spanning a
00:14:52 --> 00:14:54 significant portion of the moon's far
00:14:54 --> 00:14:56 side may hold secrets that could
00:14:56 --> 00:14:58 revolutionize our understanding of lunar
00:14:58 --> 00:15:01 formation. Recent research suggests this
00:15:01 --> 00:15:03 basin contains pristine fragments of the
00:15:03 --> 00:15:05 moon's mantle and remnants of an ancient
00:15:05 --> 00:15:07 magma ocean dating back to when our
00:15:07 --> 00:15:09 lunar companion was still cooling and
00:15:09 --> 00:15:12 solidifying after its violent birth.
00:15:12 --> 00:15:14 These materials offer a rare geological
00:15:14 --> 00:15:16 time capsule, preserving evidence from
00:15:16 --> 00:15:19 the final stages of the moon's formation
00:15:19 --> 00:15:21 process. What makes this discovery
00:15:21 --> 00:15:23 particularly intriguing is how it
00:15:23 --> 00:15:24 challenges previous scientific
00:15:24 --> 00:15:27 assumptions. Researchers studying the
00:15:27 --> 00:15:29 basin's distinctive teardrop shape have
00:15:30 --> 00:15:32 determined that the massive impactor was
00:15:32 --> 00:15:34 actually moving southward when it struck
00:15:34 --> 00:15:37 the lunar surface, not northward as
00:15:37 --> 00:15:39 previously thought. As planetary
00:15:39 --> 00:15:41 scientist Jeff Andrews Hannah from the
00:15:41 --> 00:15:43 University of Arizona noted, "We have
00:15:43 --> 00:15:45 had the data we needed to measure the
00:15:45 --> 00:15:47 shape of the basin for a long time. It
00:15:47 --> 00:15:48 just took a different perspective to
00:15:48 --> 00:15:51 view the basin this way. The impact was
00:15:51 --> 00:15:53 so powerful that it appears to have
00:15:53 --> 00:15:55 punctured through the lunar crust,
00:15:55 --> 00:15:56 allowing material from the still
00:15:56 --> 00:15:58 crystallizing magma ocean beneath to
00:15:58 --> 00:16:01 seep upward. This explains the presence
00:16:01 --> 00:16:03 of thorium and other distinctive
00:16:03 --> 00:16:04 elements consistent with creep
00:16:04 --> 00:16:07 materials, potassium, rare earth
00:16:07 --> 00:16:09 elements, and phosphorus found across
00:16:09 --> 00:16:12 the basin floor. This excavation
00:16:12 --> 00:16:14 provides a unique window into the moon's
00:16:14 --> 00:16:16 interior during a critical period of its
00:16:16 --> 00:16:19 evolution. When the moon first formed
00:16:19 --> 00:16:20 from debris following a collision
00:16:20 --> 00:16:23 between Earth and a Mars-ized object,
00:16:23 --> 00:16:25 both bodies were briefly liquefied. As
00:16:25 --> 00:16:28 the moon cooled, low density minerals
00:16:28 --> 00:16:30 floated upward to form the crust while
00:16:30 --> 00:16:33 denser materials sank inward, creating
00:16:33 --> 00:16:36 the distinct layers we observe today.
00:16:36 --> 00:16:38 The South Pole Aken Basin effectively
00:16:38 --> 00:16:40 captured a snapshot of this process in
00:16:40 --> 00:16:42 action, preserving evidence of the magma
00:16:42 --> 00:16:45 ocean's composition at a specific moment
00:16:45 --> 00:16:47 in lunar history. By analyzing these
00:16:48 --> 00:16:50 materials, scientists hope to refine our
00:16:50 --> 00:16:52 timeline of exactly when and how Earth's
00:16:52 --> 00:16:54 companion took
00:16:54 --> 00:16:56 shape. The upcoming Artemis missions
00:16:56 --> 00:16:58 represent a once- in a generation
00:16:58 --> 00:16:59 opportunity to answer fundamental
00:16:59 --> 00:17:02 questions about lunar formation. When
00:17:02 --> 00:17:05 astronauts return to the moon in 2026,
00:17:05 --> 00:17:07 they'll be able to collect and bring
00:17:07 --> 00:17:09 back samples from the South Pole Aken
00:17:09 --> 00:17:11 Basin, giving scientists direct access
00:17:11 --> 00:17:13 to materials from the moon's ancient
00:17:13 --> 00:17:16 mantle. These samples are particularly
00:17:16 --> 00:17:18 valuable because they can be compared
00:17:18 --> 00:17:20 with materials already in our
00:17:20 --> 00:17:23 possession. During the Apollo missions
00:17:23 --> 00:17:26 of the 1960s and 70s, astronauts
00:17:26 --> 00:17:28 returned with rocks from the procelarum
00:17:28 --> 00:17:31 creep terrain, another region rich in
00:17:31 --> 00:17:33 those distinctive potassium, rare earth
00:17:33 --> 00:17:36 elements, and phosphorous materials.
00:17:36 --> 00:17:39 More recently, China's Chang 5 mission
00:17:39 --> 00:17:43 in 2020 and Chang 6 in 2024 have added
00:17:43 --> 00:17:45 to our collection of lunar samples with
00:17:45 --> 00:17:47 the latter specifically returning
00:17:47 --> 00:17:49 materials from the south pole atken
00:17:49 --> 00:17:52 basin. What makes this scientific
00:17:52 --> 00:17:54 opportunity so compelling is that these
00:17:54 --> 00:17:56 different areas represent distinct
00:17:56 --> 00:17:59 snapshots in time. By analyzing
00:17:59 --> 00:18:01 materials from both regions, scientists
00:18:01 --> 00:18:03 can observe how the lunar magma ocean
00:18:03 --> 00:18:05 evolved during different periods. It's
00:18:06 --> 00:18:07 like having photographs of a developing
00:18:07 --> 00:18:10 child taken years apart. The differences
00:18:10 --> 00:18:12 tell a story of growth and change.
00:18:12 --> 00:18:14 Andrew's Hannah emphasized that this
00:18:14 --> 00:18:16 research is about more than just
00:18:16 --> 00:18:19 understanding the moon. The magma ocean
00:18:19 --> 00:18:21 is inextricably tied to the birth of
00:18:21 --> 00:18:23 Earth. He explained, "While scientists
00:18:23 --> 00:18:25 have general timelines for how long it
00:18:25 --> 00:18:27 took the lunar magma to crystallize,
00:18:27 --> 00:18:30 precise dating remains challenging. Once
00:18:30 --> 00:18:32 Artemis astronauts return with these
00:18:32 --> 00:18:34 samples, laboratory analysis can
00:18:34 --> 00:18:36 determine a precise age for the South
00:18:36 --> 00:18:38 Pole Aken basin, which will provide an
00:18:38 --> 00:18:41 exact timeline for the latestage magma
00:18:41 --> 00:18:43 ocean crystallization. This data will
00:18:43 --> 00:18:45 help scientists refine models of how
00:18:45 --> 00:18:47 both the moon and earth formed and
00:18:47 --> 00:18:49 evolved in their earliest days.
00:18:49 --> 00:18:51 The comparison between the south pole
00:18:51 --> 00:18:54 atken basin and the procelerum creep
00:18:54 --> 00:18:56 terrain holds additional significance
00:18:56 --> 00:18:58 because previous theories suggested the
00:18:58 --> 00:19:01 massive impact that created the basin
00:19:01 --> 00:19:03 might have pushed magma ocean material
00:19:03 --> 00:19:05 to the opposite side of the moon forming
00:19:05 --> 00:19:08 the pristryum region. New evidence
00:19:08 --> 00:19:10 indicates these areas formed
00:19:10 --> 00:19:13 independently with the south pole aten
00:19:13 --> 00:19:16 impact occurring earlier in lunar
00:19:16 --> 00:19:19 history. And with that, we wrap up our
00:19:19 --> 00:19:21 cosmic journey for today. From black
00:19:21 --> 00:19:23 holes hurling matter into deep space to
00:19:24 --> 00:19:25 new revelations about the moon's ancient
00:19:25 --> 00:19:28 magma oceans, we've traveled across our
00:19:28 --> 00:19:31 solar system and beyond. The universe
00:19:31 --> 00:19:33 continues to reveal its secrets to those
00:19:33 --> 00:19:36 patient enough to look and listen. As we
00:19:36 --> 00:19:39 observe Africa, taking bold new steps
00:19:39 --> 00:19:41 into the space arena and anticipate what
00:19:41 --> 00:19:43 Artemis astronauts might discover on the
00:19:43 --> 00:19:45 lunar surface. It's clear that space
00:19:45 --> 00:19:47 exploration remains one of humanity's
00:19:47 --> 00:19:51 greatest adventures. I'm Anna and I want
00:19:51 --> 00:19:52 to thank you for spending this time
00:19:52 --> 00:19:55 exploring the cosmos with me. If you
