00:00:18 --> 00:00:21 week of rocket launches plus we'll
00:00:21 --> 00:00:23 investigate the physics of tiny black
00:00:23 --> 00:00:25 holes learn about the possible origins
00:00:25 --> 00:00:28 of our first Interstellar visitor and
00:00:28 --> 00:00:30 discover why some Planet forming discs
00:00:30 --> 00:00:33 seem to never grow up stay with me as we
00:00:33 --> 00:00:34 journey through these fascinating
00:00:34 --> 00:00:36 stories from the final
00:00:36 --> 00:00:38 frontier in what might be one of the
00:00:38 --> 00:00:40 most extraordinary discoveries of recent
00:00:40 --> 00:00:43 times NASA scientists have identified
00:00:43 --> 00:00:45 what they believe to be the fastest
00:00:45 --> 00:00:48 moving planetary system ever observed
00:00:48 --> 00:00:50 picture this a star hurdling through
00:00:50 --> 00:00:53 space at an astonishing 1.2 million
00:00:53 --> 00:00:56 milph and it's not traveling alone this
00:00:56 --> 00:00:58 Cosmic Speedster is dragging along what
00:00:58 --> 00:01:00 appears to be a super Neptune sized
00:01:00 --> 00:01:03 Planet making this Duo the fastest known
00:01:03 --> 00:01:05 planetary system in our
00:01:05 --> 00:01:08 galaxy this remarkable Discovery was
00:01:08 --> 00:01:09 made possible thanks to a phenomenon
00:01:09 --> 00:01:11 predicted by Einstein's theory of
00:01:11 --> 00:01:13 general relativity called gravitational
00:01:13 --> 00:01:15 lensing the system was first detected
00:01:15 --> 00:01:18 back in 2011 when its gravity caused a
00:01:18 --> 00:01:20 slight warping of light from background
00:01:20 --> 00:01:22 Stars after a decade of follow-up
00:01:22 --> 00:01:24 observations using the kek observatory
00:01:24 --> 00:01:27 in Hawaii and data from the Gaia
00:01:27 --> 00:01:29 spacecraft scientists were able to
00:01:29 --> 00:01:31 confirm their find finding the star
00:01:31 --> 00:01:34 system is located approximately 24
00:01:34 --> 00:01:36 light years away near the dense central
00:01:36 --> 00:01:38 bulge of the Milky Way what's
00:01:38 --> 00:01:41 particularly fascinating is that this
00:01:41 --> 00:01:43 system is moving so fast it actually
00:01:43 --> 00:01:46 exceeds our Galaxy's escape
00:01:46 --> 00:01:48 velocity this means it's literally in
00:01:48 --> 00:01:50 the process of breaking free from the
00:01:50 --> 00:01:52 Milky Way's gravitational grip and could
00:01:52 --> 00:01:54 eventually become an Intergalactic
00:01:54 --> 00:01:56 Wanderer while the team has confirmed
00:01:57 --> 00:01:58 the star's incredible speed in two
00:01:58 --> 00:02:00 Dimensions there's a possibility it
00:02:00 --> 00:02:02 could be moving even faster potentially
00:02:02 --> 00:02:06 up to 1.3 million mph if it's also
00:02:06 --> 00:02:08 moving toward or away from Earth this
00:02:08 --> 00:02:10 would make it not just a recordbreaker
00:02:10 --> 00:02:12 but a system truly pushing the
00:02:12 --> 00:02:14 boundaries of what we thought possible
00:02:14 --> 00:02:16 in terms of planetary survival at such
00:02:16 --> 00:02:17 extreme
00:02:17 --> 00:02:20 velocities let's turn our attention now
00:02:20 --> 00:02:22 to this week's launches space
00:02:22 --> 00:02:24 enthusiasts are in for a treat this week
00:02:24 --> 00:02:26 with an action-packed launch schedule
00:02:26 --> 00:02:30 featuring four exciting missions space X
00:02:30 --> 00:02:31 is leading the charge with three
00:02:31 --> 00:02:34 separate Falcon 9 launches carrying
00:02:34 --> 00:02:36 their starlink satellites while rocket
00:02:36 --> 00:02:38 lab rounds out the lineup with their
00:02:38 --> 00:02:41 60th electron Mission from New Zealand
00:02:41 --> 00:02:43 one of these launches is particularly
00:02:43 --> 00:02:45 noteworthy as it marks a historic first
00:02:46 --> 00:02:47 SpaceX will attempt to land a falcon 9
00:02:47 --> 00:02:49 booster in Bahamian Waters near the
00:02:50 --> 00:02:52 island of Exuma this new Landing Zone
00:02:52 --> 00:02:54 made possible through an agreement with
00:02:54 --> 00:02:57 Bahamian authorities offers calmer more
00:02:57 --> 00:02:58 sheltered Waters compared to the open
00:02:58 --> 00:03:00 Atlantic this should provide more
00:03:00 --> 00:03:02 reliable Landing conditions and enable
00:03:02 --> 00:03:04 SpaceX to explore new launch
00:03:04 --> 00:03:07 trajectories from Cape Canaveral the
00:03:07 --> 00:03:10 first starlink mission will deploy 23 V2
00:03:10 --> 00:03:12 mini satellites to low earth orbit with
00:03:12 --> 00:03:16 the veteran booster b180 making it 16th
00:03:16 --> 00:03:18 flight meanwhile rocket lab's Mission
00:03:18 --> 00:03:21 playfully titled fasten your space belts
00:03:21 --> 00:03:23 will carry a black Sky gen 3 Earth
00:03:23 --> 00:03:25 Imaging satellite these new satellites
00:03:25 --> 00:03:27 will provide enhanced Imaging
00:03:27 --> 00:03:30 capabilities with very high resolution
00:03:30 --> 00:03:34 35 CM imagery combined with AI enabled
00:03:34 --> 00:03:36 analytics the week's remaining starlink
00:03:36 --> 00:03:38 launches will continue spacex's rapid
00:03:38 --> 00:03:40 deployment of their internet
00:03:40 --> 00:03:42 constellation with one launching from
00:03:42 --> 00:03:43 vandenbberg space force base in
00:03:43 --> 00:03:46 California and another from Cape
00:03:46 --> 00:03:47 Canaveral in
00:03:47 --> 00:03:49 Florida this intense launch Cadence
00:03:49 --> 00:03:51 demonstrates the growing momentum in
00:03:51 --> 00:03:53 commercial space operations and the
00:03:53 --> 00:03:55 increasing reliability of reusable
00:03:55 --> 00:03:57 rocket
00:03:57 --> 00:04:00 technology next up today
00:04:00 --> 00:04:01 scientists have made a fascinating
00:04:01 --> 00:04:03 breakthrough in understanding our Moon's
00:04:03 --> 00:04:05 earliest days thanks to new analysis of
00:04:06 --> 00:04:07 rocks collected during the Apollo
00:04:08 --> 00:04:10 missions by examining these lunar
00:04:10 --> 00:04:12 samples researchers have pinpointed that
00:04:12 --> 00:04:15 our Cosmic companion solidified
00:04:15 --> 00:04:18 approximately 4.43 billion years ago a
00:04:18 --> 00:04:20 timeline that remarkably coincides with
00:04:20 --> 00:04:23 Earth becoming a habitable world the key
00:04:23 --> 00:04:25 to this discovery lies in a unique
00:04:25 --> 00:04:26 substance found in moon rocks called
00:04:26 --> 00:04:29 creep an acronym for potassium rare
00:04:29 --> 00:04:31 Earth elements and
00:04:31 --> 00:04:33 phosphorus this material formed as The
00:04:33 --> 00:04:35 Last Remnant of the moon's original
00:04:35 --> 00:04:37 magma ocean making it an invaluable
00:04:37 --> 00:04:39 window into our satellites cooling
00:04:39 --> 00:04:42 process by analyzing the decay of a rare
00:04:42 --> 00:04:45 Earth element called lutetium into
00:04:45 --> 00:04:47 hafnium within these rocks researchers
00:04:47 --> 00:04:49 were able to determine that creep formed
00:04:49 --> 00:04:51 about 140 million years after the Solar
00:04:52 --> 00:04:54 System's birth this timing tells us that
00:04:54 --> 00:04:55 the moon was still Cooling and
00:04:55 --> 00:04:57 crystallizing while being bombarded by
00:04:57 --> 00:04:59 Leftover planetary debris from the solar
00:04:59 --> 00:05:01 systems formation what makes this
00:05:02 --> 00:05:04 finding particularly significant is how
00:05:04 --> 00:05:06 it aligns with Earth's own timeline the
00:05:06 --> 00:05:08 impact that created the moon was likely
00:05:08 --> 00:05:10 the last major Collision Earth
00:05:10 --> 00:05:12 experienced potentially marking the
00:05:12 --> 00:05:14 beginning of our planet's transformation
00:05:14 --> 00:05:17 into a stable life-supporting world this
00:05:17 --> 00:05:19 new dating method not only helps us
00:05:19 --> 00:05:21 understand the moon's Evolution but
00:05:21 --> 00:05:23 provides crucial context for Earth's
00:05:23 --> 00:05:26 early history as well these findings
00:05:26 --> 00:05:28 come at an exciting time as future
00:05:28 --> 00:05:30 Artemis missions to the lunar South Pole
00:05:30 --> 00:05:33 could provide even more samples to study
00:05:33 --> 00:05:35 potentially confirming whether this
00:05:35 --> 00:05:37 creep layer exists uniformly across the
00:05:37 --> 00:05:38 moon
00:05:38 --> 00:05:40 surface have you ever wondered what
00:05:40 --> 00:05:42 would happen if a microscopic black hole
00:05:42 --> 00:05:45 passed right through your body well a
00:05:45 --> 00:05:47 fascinating new study has tackled this
00:05:48 --> 00:05:50 exact question and the results might
00:05:50 --> 00:05:52 surprise you while most of us would
00:05:52 --> 00:05:54 assume instant destruction the reality
00:05:54 --> 00:05:57 is more nuanced the research focused on
00:05:57 --> 00:05:59 primordial black holes theoretical
00:05:59 --> 00:06:01 objects that may have formed in the
00:06:01 --> 00:06:03 universe's earliest moments these would
00:06:03 --> 00:06:05 be far smaller than the Stellar black
00:06:05 --> 00:06:08 holes we typically think of ranging from
00:06:08 --> 00:06:09 the mass of an atom to several times
00:06:09 --> 00:06:12 Earth's mass for a black hole to be
00:06:12 --> 00:06:14 potentially lethal it would need to be
00:06:14 --> 00:06:16 in the same mass range as
00:06:16 --> 00:06:19 asteroids the study examined two main
00:06:19 --> 00:06:22 effects tidal forces and shock waves
00:06:22 --> 00:06:24 while the tidal forces from such a tiny
00:06:24 --> 00:06:25 black hole passing through your limbs or
00:06:25 --> 00:06:28 torso might only cause localized damage
00:06:28 --> 00:06:30 similar to a needle A Passage through
00:06:30 --> 00:06:32 your brain could be fatal due to the
00:06:32 --> 00:06:34 delicate nature of brain cells but the
00:06:34 --> 00:06:37 real danger would come from shock waves
00:06:37 --> 00:06:40 a black hole with just 1.4 X10
00:06:40 --> 00:06:43 circumflex 14 kg of mass could generate
00:06:43 --> 00:06:46 energy waves comparable to a22 caliber
00:06:46 --> 00:06:49 bullet definitely enough to cause
00:06:49 --> 00:06:51 serious harm before you start worrying
00:06:52 --> 00:06:54 though here's the good news even if
00:06:54 --> 00:06:56 these primordial black holes exist the
00:06:56 --> 00:06:58 chances of one passing through anyone in
00:06:58 --> 00:07:01 their lifetime are less than one in 10
00:07:01 --> 00:07:03 trillion so while it makes for
00:07:03 --> 00:07:05 fascinating physics it's not something
00:07:05 --> 00:07:07 that should keep you up at
00:07:07 --> 00:07:10 night let's revisit an old friend now
00:07:10 --> 00:07:12 new research is shedding light on the
00:07:12 --> 00:07:15 mysterious origins of umu mua that
00:07:15 --> 00:07:17 bizarre Interstellar object that briefly
00:07:17 --> 00:07:19 visited our solar system in
00:07:19 --> 00:07:21 2017 scientists have been puzzling over
00:07:21 --> 00:07:23 how such an unusual object could have
00:07:23 --> 00:07:26 formed and now they might have an answer
00:07:26 --> 00:07:28 using numerical simulations researchers
00:07:29 --> 00:07:30 have found that solar systems with giant
00:07:30 --> 00:07:32 planets could be the perfect breeding
00:07:32 --> 00:07:35 grounds for umu muua like objects the
00:07:35 --> 00:07:37 key lies in a process called tidal
00:07:37 --> 00:07:39 fragmentation where a large comet-like
00:07:39 --> 00:07:42 body passes too close to its star at
00:07:42 --> 00:07:44 high speed shattering into elongated
00:07:44 --> 00:07:47 shards what makes this particularly
00:07:47 --> 00:07:49 interesting is that these fragments
00:07:49 --> 00:07:51 would have a unique composition a rocky
00:07:51 --> 00:07:54 outer shell with subsurface ice hidden
00:07:54 --> 00:07:56 within this could explain umam mua's
00:07:56 --> 00:07:58 peculiar Behavior combining both
00:07:58 --> 00:08:00 asteroid like and comet-like
00:08:00 --> 00:08:03 properties the study suggests that
00:08:03 --> 00:08:05 systems with Jupiter sized planets at
00:08:05 --> 00:08:07 reasonable distances from their stars
00:08:07 --> 00:08:09 are especially good at producing these
00:08:09 --> 00:08:12 objects however the rate at which
00:08:12 --> 00:08:14 they're created still doesn't quite
00:08:14 --> 00:08:16 match what we'd expect to see suggesting
00:08:16 --> 00:08:18 there might be more to the story
00:08:18 --> 00:08:20 multiple Planet systems might be even
00:08:20 --> 00:08:22 better candidates as they're more
00:08:22 --> 00:08:24 efficient at ejecting objects into
00:08:24 --> 00:08:26 Interstellar space so while we're
00:08:27 --> 00:08:28 getting closer to understanding umam
00:08:28 --> 00:08:30 mua's origin
00:08:30 --> 00:08:32 it seems this Cosmic Wanderer still has
00:08:32 --> 00:08:34 some Secrets left to
00:08:34 --> 00:08:37 reveal finally today in a fascinating
00:08:37 --> 00:08:39 Twist on our understanding of planetary
00:08:39 --> 00:08:41 formation astronomers have discovered
00:08:41 --> 00:08:43 that some Planet forming diss are
00:08:43 --> 00:08:45 refusing to grow up quite literally
00:08:45 --> 00:08:47 these discs now nicknamed Peter Pan
00:08:47 --> 00:08:50 discs are being found around low mass
00:08:50 --> 00:08:52 stars and are lasting far longer than
00:08:52 --> 00:08:55 conventional theory suggest they should
00:08:55 --> 00:08:57 using the powerful aacom large millimet
00:08:57 --> 00:08:59 submillimeter array scientists have
00:08:59 --> 00:09:01 found these discs are still rich in
00:09:01 --> 00:09:04 Planet building materials even after 30
00:09:04 --> 00:09:06 million years that's three times longer
00:09:06 --> 00:09:08 than the typical 10 million year
00:09:08 --> 00:09:10 lifespan we expected even more
00:09:11 --> 00:09:12 surprisingly they're packed with
00:09:12 --> 00:09:13 hydrocarbons and show chemical
00:09:13 --> 00:09:15 signatures never before seen in such
00:09:15 --> 00:09:18 mature diss this extended lifetime could
00:09:19 --> 00:09:20 completely change our understanding of
00:09:20 --> 00:09:22 how planets form around smaller Stars
00:09:22 --> 00:09:25 the longer these discs stick around the
00:09:25 --> 00:09:27 more time there is for planetary cores
00:09:27 --> 00:09:29 to build up and for complex chemical
00:09:29 --> 00:09:31 processes to unfold it's particularly
00:09:31 --> 00:09:33 intriguing because these conditions
00:09:33 --> 00:09:35 might favor the formation of planets
00:09:35 --> 00:09:37 with unique characteristics possibly
00:09:38 --> 00:09:39 including worlds with carbon-rich
00:09:39 --> 00:09:42 atmospheres similar to Saturn's moon
00:09:42 --> 00:09:44 Titan while these Peter Pan discs appear
