00:00:15 --> 00:00:17 dive into fascinating new research
00:00:17 --> 00:00:19 suggesting that the first supernovas may
00:00:19 --> 00:00:21 have flooded the universe with water
00:00:21 --> 00:00:23 just 100 million years after the big
00:00:23 --> 00:00:26 bang we'll also check in on Rocket lab's
00:00:26 --> 00:00:28 first launch of 2025 and bring you
00:00:28 --> 00:00:30 breaking news about major changes
00:00:30 --> 00:00:32 potentially coming to NASA's space
00:00:32 --> 00:00:34 launch system program plus we've got
00:00:34 --> 00:00:36 intriguing discoveries about a possible
00:00:36 --> 00:00:38 super massive black hole in one of our
00:00:38 --> 00:00:41 nearest Galactic neighbors and evidence
00:00:41 --> 00:00:43 that some asteroids in our solar system
00:00:43 --> 00:00:45 might be ancient planetary
00:00:45 --> 00:00:47 fragments so let's blast off into
00:00:47 --> 00:00:50 today's space news in a groundbreaking
00:00:50 --> 00:00:52 news study scientists have discovered
00:00:52 --> 00:00:54 that the universe's first supernovas may
00:00:54 --> 00:00:56 have created vast amounts of water much
00:00:56 --> 00:00:58 earlier than previously thought
00:00:58 --> 00:01:00 potentially setting the stage for life
00:01:00 --> 00:01:02 just 100 million years after the big
00:01:02 --> 00:01:05 bang this fascinating finding challenges
00:01:05 --> 00:01:07 our current understanding of how water
00:01:07 --> 00:01:10 formed in the early Universe until now
00:01:10 --> 00:01:12 scientists believed that water gradually
00:01:12 --> 00:01:14 accumulated over billions of years as
00:01:14 --> 00:01:16 hydrogen combined with oxygen expelled
00:01:16 --> 00:01:19 from dying Stars however new simulations
00:01:19 --> 00:01:21 suggest a much more dramatic origin
00:01:21 --> 00:01:23 story when the first generation of
00:01:23 --> 00:01:26 massive stars exploded as supernovas
00:01:26 --> 00:01:27 they may have created the perfect
00:01:27 --> 00:01:29 conditions for water formation in their
00:01:29 --> 00:01:30 wake
00:01:30 --> 00:01:33 these early stars were true Cosmic
00:01:33 --> 00:01:36 Giants each containing about 200 times
00:01:36 --> 00:01:39 the mass of our sun when they exploded
00:01:39 --> 00:01:41 they left behind dense clouds of
00:01:41 --> 00:01:44 hydrogen oxygen and other elements
00:01:44 --> 00:01:46 within these cosmic clouds water could
00:01:46 --> 00:01:48 have formed at concentrations up to 30
00:01:48 --> 00:01:50 times higher than what we observe in
00:01:50 --> 00:01:54 interstellar space today if confirmed
00:01:54 --> 00:01:56 this discovery would have profound
00:01:56 --> 00:01:57 implications for our understanding of
00:01:57 --> 00:02:00 both Galaxy Evolution and the potential
00:02:00 --> 00:02:02 for early life in the universe it
00:02:02 --> 00:02:04 suggests that one of life's most
00:02:04 --> 00:02:06 essential ingredients was present in
00:02:06 --> 00:02:08 significant quantities far earlier than
00:02:09 --> 00:02:11 we imagined potentially seeding the
00:02:11 --> 00:02:13 first galaxies with water between 100
00:02:13 --> 00:02:18 and 200 million years after the big bang
00:02:18 --> 00:02:20 however this Theory isn't without its
00:02:20 --> 00:02:22 challenges scientists have never
00:02:22 --> 00:02:24 directly observed these early stars and
00:02:24 --> 00:02:26 if there was such abundant water in the
00:02:26 --> 00:02:29 early Universe we might expect to see
00:02:29 --> 00:02:31 more of it in our Cosmic surroundings
00:02:31 --> 00:02:33 today some researchers suggest the
00:02:33 --> 00:02:35 universe may have undergone a mysterious
00:02:35 --> 00:02:37 drying out period though the mechanism
00:02:37 --> 00:02:40 for such an event remains unclear while
00:02:40 --> 00:02:43 water is crucial for Life as we know it
00:02:43 --> 00:02:44 its early presence alone doesn't
00:02:44 --> 00:02:47 guarantee that life emerged during this
00:02:47 --> 00:02:51 period nevertheless This research opens
00:02:51 --> 00:02:53 up exciting new possibilities about the
00:02:53 --> 00:02:54 conditions present in the infant
00:02:54 --> 00:02:57 universe and challenges us to reconsider
00:02:57 --> 00:03:00 our assumptions about Cosmic evolution
00:03:00 --> 00:03:03 next up in today's news rocket lab is
00:03:03 --> 00:03:06 gearing up for an exciting start to 2025
00:03:06 --> 00:03:07 with their first orbital launch of the
00:03:07 --> 00:03:09 Year scheduled from their launch complex
00:03:09 --> 00:03:12 one in Mahia New Zealand the Mission
00:03:12 --> 00:03:15 cleverly named iot for you and me is set
00:03:15 --> 00:03:16 to lift off this Sunday morning local
00:03:16 --> 00:03:19 time carrying a valuable payload of five
00:03:19 --> 00:03:21 satellites for the French Internet of
00:03:21 --> 00:03:22 Things company
00:03:22 --> 00:03:25 kise this launch marks another important
00:03:25 --> 00:03:27 step in expanding global satellite
00:03:27 --> 00:03:29 coverage for the Internet of Things each
00:03:29 --> 00:03:31 of these satellites measuring just over
00:03:31 --> 00:03:34 4 and 1/2x 5 ft will be placed into a
00:03:34 --> 00:03:36 circular orbit about 400 Mi above
00:03:36 --> 00:03:39 Earth's surface they'll be traveling at
00:03:39 --> 00:03:41 an incredible speed of nearly 5 m per
00:03:41 --> 00:03:43 second powered by Electric propulsion
00:03:43 --> 00:03:46 systems and solar panels the mission is
00:03:46 --> 00:03:48 particularly significant as it
00:03:48 --> 00:03:50 represents the fourth of five dedicated
00:03:50 --> 00:03:52 launches needed to complete kise's
00:03:52 --> 00:03:55 ambitious constellation of 25 satellites
00:03:55 --> 00:03:58 once fully deployed this network will
00:03:58 --> 00:04:00 ensure continuous data transmission with
00:04:00 --> 00:04:02 up to 80 satellite passes every day over
00:04:02 --> 00:04:04 any point on the globe the launch was
00:04:04 --> 00:04:06 originally planned for earlier this
00:04:06 --> 00:04:08 month but had to be postponed due to a
00:04:08 --> 00:04:09 potential Collision risk with the
00:04:09 --> 00:04:12 International Space Station this kind of
00:04:12 --> 00:04:13 careful coordination and safety
00:04:13 --> 00:04:15 consideration is crucial in our
00:04:15 --> 00:04:17 increasingly crowded orbital environment
00:04:18 --> 00:04:19 rocket lab continues to demonstrate its
00:04:19 --> 00:04:21 reliability in the small satellite
00:04:21 --> 00:04:24 launch market providing regular access
00:04:24 --> 00:04:26 to space for companies looking to expand
00:04:26 --> 00:04:27 their orbital
00:04:27 --> 00:04:29 infrastructure this Mission reinforced
00:04:29 --> 00:04:31 forces their position as a key player in
00:04:31 --> 00:04:33 the commercial space industry while
00:04:33 --> 00:04:35 helping to build out the global internet
00:04:35 --> 00:04:37 of things Network that will connect
00:04:37 --> 00:04:39 devices and sensors
00:04:39 --> 00:04:41 worldwide in significant news from the
00:04:41 --> 00:04:43 Aerospace industry today Boeing has
00:04:43 --> 00:04:45 issued a stark warning about the future
00:04:45 --> 00:04:48 of NASA's space launch system program
00:04:48 --> 00:04:49 during an hastily arranged six-minute
00:04:50 --> 00:04:52 meeting Boeing's vice president and SLS
00:04:52 --> 00:04:55 program manager David ducher informed
00:04:55 --> 00:04:57 approximately 800 employees that their
00:04:57 --> 00:05:00 contracts with NASA could end as soon as
00:05:00 --> 00:05:02 march with potential layoffs looming on
00:05:02 --> 00:05:05 the horizon this development comes as
00:05:05 --> 00:05:07 Boeing prepares to issue notices under
00:05:07 --> 00:05:09 the worker adjustment and retraining
00:05:09 --> 00:05:11 notification act potentially affecting
00:05:11 --> 00:05:15 around 400 positions by April 2025 the
00:05:15 --> 00:05:16 timing of this announcement aligns with
00:05:16 --> 00:05:18 the anticipated release of President
00:05:18 --> 00:05:20 Trump's budget proposal for fiscal year
00:05:20 --> 00:05:23 2026 suggesting possible major changes
00:05:23 --> 00:05:26 to NASA's heavy lift rocket program the
00:05:26 --> 00:05:28 SLS program which has been a Cornerstone
00:05:28 --> 00:05:30 of NASA's space exploration efforts
00:05:30 --> 00:05:33 since 2011 has faced ongoing scrutiny
00:05:33 --> 00:05:36 due to its high costs and delays each
00:05:36 --> 00:05:38 launch of the massive rocket costs over
00:05:38 --> 00:05:41 $2 billion not including payload or
00:05:41 --> 00:05:44 ground systems expenses while the rocket
00:05:44 --> 00:05:46 finally made its debut flight in late
00:05:46 --> 00:05:50 2022 this came years behind schedule and
00:05:50 --> 00:05:52 billions over budget what makes this
00:05:52 --> 00:05:55 situation particularly notable is the
00:05:55 --> 00:05:57 changing landscape of space launch
00:05:57 --> 00:05:59 capabilities private companies like
00:05:59 --> 00:06:02 SpaceX and blue origin have developed
00:06:02 --> 00:06:04 their own heavy lift rockets that are
00:06:04 --> 00:06:07 not only partially reusable but operate
00:06:07 --> 00:06:10 at a fraction of the sls's cost less
00:06:10 --> 00:06:12 than on10th in fact there's reportedly
00:06:12 --> 00:06:14 been significant debate within NASA and
00:06:14 --> 00:06:17 White House leadership about the future
00:06:17 --> 00:06:19 of both the SLS rocket and the broader
00:06:19 --> 00:06:22 Artemis Moon program some advocate for
00:06:22 --> 00:06:24 completing the planned Artemis 2 and 3
00:06:24 --> 00:06:26 missions using the initial version of
00:06:26 --> 00:06:29 SLS before ending the program While
00:06:29 --> 00:06:30 others argue for an immediate
00:06:30 --> 00:06:33 cancellation to prevent further cost
00:06:33 --> 00:06:35 overruns this situation highlights the
00:06:35 --> 00:06:38 ongoing evolution in space launch
00:06:38 --> 00:06:40 technology and the challenges facing
00:06:40 --> 00:06:42 traditional government contracted space
00:06:42 --> 00:06:44 programs in an era of increasing
00:06:45 --> 00:06:47 commercial competition the outcome of
00:06:47 --> 00:06:49 these developments could significantly
00:06:49 --> 00:06:51 reshape NASA's approach to deep space
00:06:51 --> 00:06:53 exploration in the coming
00:06:53 --> 00:06:56 years time for today's black hole story
00:06:56 --> 00:06:58 in fascinating news from our Cosmic
00:06:58 --> 00:07:01 neighborhood astronomers have uncovered
00:07:01 --> 00:07:03 compelling evidence of a super massive
00:07:03 --> 00:07:05 black hole lurking in the large melanic
00:07:05 --> 00:07:08 Cloud one of the Milky Way's satellite
00:07:08 --> 00:07:10 galaxies this discovery came through an
00:07:10 --> 00:07:13 unexpected Source hypervelocity Stars
00:07:13 --> 00:07:15 racing through our galaxy at incredible
00:07:15 --> 00:07:18 speeds using data from issa's Gaia
00:07:18 --> 00:07:20 spacecraft researchers found that about
00:07:20 --> 00:07:22 half of the previously identified
00:07:22 --> 00:07:24 hypervelocity stars in our galaxy can be
00:07:24 --> 00:07:26 traced back not to the Milky Way Center
00:07:26 --> 00:07:29 but to the large melanic Cloud these
00:07:29 --> 00:07:31 Stellar speedsters are traveling at up
00:07:31 --> 00:07:34 to 1 km/ second 10 times faster than
00:07:34 --> 00:07:36 typical Stars the research team
00:07:36 --> 00:07:39 constructed detailed models showing that
00:07:39 --> 00:07:40 these high-speed stars were likely
00:07:40 --> 00:07:43 ejected by a black hole in the LMC with
00:07:43 --> 00:07:46 a mass of around 600 times that of
00:07:46 --> 00:07:48 our sun this process occurs when binary
00:07:49 --> 00:07:50 star systems get too close to the black
00:07:50 --> 00:07:52 hole resulting in one star being
00:07:53 --> 00:07:54 captured while the other is violently
00:07:54 --> 00:07:56 flung away at extreme
00:07:56 --> 00:07:58 velocities further supporting this
00:07:58 --> 00:08:00 theory is a peculiar concentration of
00:08:00 --> 00:08:04 stars known as the Leo over density the
00:08:04 --> 00:08:06 researchers models show that this
00:08:06 --> 00:08:08 Stellar Gathering is consistent with
00:08:08 --> 00:08:10 stars ejected from the LMC by its hidden
00:08:10 --> 00:08:13 black hole this discovery challenges our
00:08:13 --> 00:08:15 current understanding of dwarf galaxies
00:08:15 --> 00:08:17 like the LMC which weren't thought to
00:08:17 --> 00:08:20 Harbor such massive black holes this
00:08:20 --> 00:08:23 finding has significant implications for
00:08:23 --> 00:08:25 our understanding of Galaxy Evolution if
00:08:25 --> 00:08:27 astronomers have been missing black
00:08:27 --> 00:08:30 holes in smaller galaxies like the LMC
00:08:30 --> 00:08:32 our theories about how galaxies grow and
00:08:32 --> 00:08:35 develop may need substantial revision it
00:08:35 --> 00:08:36 also demonstrates how the motion of
00:08:36 --> 00:08:39 entire galaxies can influence the
00:08:39 --> 00:08:41 dramatic Stellar ejections we observe
00:08:41 --> 00:08:43 adding another layer of complexity to
00:08:43 --> 00:08:45 our Cosmic
00:08:45 --> 00:08:47 understanding an intriguing Discovery
00:08:47 --> 00:08:49 has astronomers rethinking the early
00:08:49 --> 00:08:51 history of our solar system two
00:08:51 --> 00:08:53 asteroids floating in the main asteroid
00:08:53 --> 00:08:55 belt between Mars and Jupiter might
00:08:55 --> 00:08:57 actually be ancient remnants of
00:08:57 --> 00:08:58 planetary embryos from our Cosmic
00:08:58 --> 00:09:01 neighborhood earliest days these
00:09:01 --> 00:09:03 asteroids named aspirina and Lou Allen
00:09:03 --> 00:09:05 share remarkable similarities with a
00:09:05 --> 00:09:07 rare group of meteorites called angrites
00:09:07 --> 00:09:09 which are some of the oldest known rocks
00:09:09 --> 00:09:11 in our solar system this connection is
00:09:11 --> 00:09:13 particularly exciting because it could
00:09:13 --> 00:09:16 provide a direct link to the tumultuous
00:09:16 --> 00:09:18 period when our planets were first
00:09:18 --> 00:09:20 forming scientists reached this
00:09:20 --> 00:09:22 conclusion by comparing the light
00:09:22 --> 00:09:23 signatures of these asteroids with
00:09:23 --> 00:09:25 samples of angrite meteorites found on
00:09:25 --> 00:09:28 Earth the larger of the two aspirina
00:09:28 --> 00:09:31 spans about 32 m in diameter and likely
00:09:31 --> 00:09:33 represents a significant piece of a much
00:09:33 --> 00:09:36 larger ancient body possibly one that
00:09:36 --> 00:09:39 was closer in size to the moon or Mars
00:09:39 --> 00:09:40 the discovery of these potential
00:09:40 --> 00:09:43 planetary fragments offers us a unique
00:09:43 --> 00:09:45 window into the violent early days of
00:09:45 --> 00:09:48 our solar system during this period
00:09:48 --> 00:09:51 numerous planetary embryos bodies larger
00:09:51 --> 00:09:53 than asteroids but smaller than fully
00:09:53 --> 00:09:56 formed planets collided and merged as
00:09:56 --> 00:09:59 they grew into the planets we know today
00:09:59 --> 00:10:01 many were destroyed in the process
00:10:01 --> 00:10:03 leaving behind only fragments as
00:10:03 --> 00:10:04 evidence of their
