your daily dose of space and astronomy


00:00:05.040 --> 00:00:07.349
news we have a great lineup of stories


00:00:07.359 --> 00:00:09.430
for you today from groundbreaking


00:00:09.440 --> 00:00:11.230
discoveries about water formation in the


00:00:11.240 --> 00:00:13.030
early Universe to the latest


00:00:13.040 --> 00:00:15.629
developments in space exploration we'll


00:00:15.639 --> 00:00:17.429
dive into fascinating new research


00:00:17.439 --> 00:00:19.470
suggesting that the first supernovas may


00:00:19.480 --> 00:00:21.310
have flooded the universe with water


00:00:21.320 --> 00:00:23.750
just 100 million years after the big


00:00:23.760 --> 00:00:26.429
bang we'll also check in on Rocket lab's


00:00:26.439 --> 00:00:28.910
first launch of 2025 and bring you


00:00:28.920 --> 00:00:30.550
breaking news about major changes


00:00:30.560 --> 00:00:32.190
potentially coming to NASA's space


00:00:32.200 --> 00:00:34.869
launch system program plus we've got


00:00:34.879 --> 00:00:36.750
intriguing discoveries about a possible


00:00:36.760 --> 00:00:38.950
super massive black hole in one of our


00:00:38.960 --> 00:00:41.430
nearest Galactic neighbors and evidence


00:00:41.440 --> 00:00:43.350
that some asteroids in our solar system


00:00:43.360 --> 00:00:45.350
might be ancient planetary


00:00:45.360 --> 00:00:47.750
fragments so let's blast off into


00:00:47.760 --> 00:00:50.029
today's space news in a groundbreaking


00:00:50.039 --> 00:00:52.110
news study scientists have discovered


00:00:52.120 --> 00:00:54.630
that the universe's first supernovas may


00:00:54.640 --> 00:00:56.790
have created vast amounts of water much


00:00:56.800 --> 00:00:58.750
earlier than previously thought


00:00:58.760 --> 00:01:00.590
potentially setting the stage for life


00:01:00.600 --> 00:01:02.869
just 100 million years after the big


00:01:02.879 --> 00:01:05.429
bang this fascinating finding challenges


00:01:05.439 --> 00:01:07.109
our current understanding of how water


00:01:07.119 --> 00:01:10.510
formed in the early Universe until now


00:01:10.520 --> 00:01:12.469
scientists believed that water gradually


00:01:12.479 --> 00:01:14.270
accumulated over billions of years as


00:01:14.280 --> 00:01:16.510
hydrogen combined with oxygen expelled


00:01:16.520 --> 00:01:19.469
from dying Stars however new simulations


00:01:19.479 --> 00:01:21.429
suggest a much more dramatic origin


00:01:21.439 --> 00:01:23.670
story when the first generation of


00:01:23.680 --> 00:01:26.350
massive stars exploded as supernovas


00:01:26.360 --> 00:01:27.910
they may have created the perfect


00:01:27.920 --> 00:01:29.550
conditions for water formation in their


00:01:29.560 --> 00:01:30.910
wake


00:01:30.920 --> 00:01:33.030
these early stars were true Cosmic


00:01:33.040 --> 00:01:36.109
Giants each containing about 200 times


00:01:36.119 --> 00:01:39.630
the mass of our sun when they exploded


00:01:39.640 --> 00:01:41.469
they left behind dense clouds of


00:01:41.479 --> 00:01:44.590
hydrogen oxygen and other elements


00:01:44.600 --> 00:01:46.870
within these cosmic clouds water could


00:01:46.880 --> 00:01:48.910
have formed at concentrations up to 30


00:01:48.920 --> 00:01:50.870
times higher than what we observe in


00:01:50.880 --> 00:01:54.429
interstellar space today if confirmed


00:01:54.439 --> 00:01:56.029
this discovery would have profound


00:01:56.039 --> 00:01:57.870
implications for our understanding of


00:01:57.880 --> 00:02:00.550
both Galaxy Evolution and the potential


00:02:00.560 --> 00:02:02.870
for early life in the universe it


00:02:02.880 --> 00:02:04.590
suggests that one of life's most


00:02:04.600 --> 00:02:06.749
essential ingredients was present in


00:02:06.759 --> 00:02:08.990
significant quantities far earlier than


00:02:09.000 --> 00:02:11.350
we imagined potentially seeding the


00:02:11.360 --> 00:02:13.949
first galaxies with water between 100


00:02:13.959 --> 00:02:18.190
and 200 million years after the big bang


00:02:18.200 --> 00:02:20.430
however this Theory isn't without its


00:02:20.440 --> 00:02:22.470
challenges scientists have never


00:02:22.480 --> 00:02:24.910
directly observed these early stars and


00:02:24.920 --> 00:02:26.949
if there was such abundant water in the


00:02:26.959 --> 00:02:29.309
early Universe we might expect to see


00:02:29.319 --> 00:02:31.309
more of it in our Cosmic surroundings


00:02:31.319 --> 00:02:33.670
today some researchers suggest the


00:02:33.680 --> 00:02:35.589
universe may have undergone a mysterious


00:02:35.599 --> 00:02:37.869
drying out period though the mechanism


00:02:37.879 --> 00:02:40.670
for such an event remains unclear while


00:02:40.680 --> 00:02:43.110
water is crucial for Life as we know it


00:02:43.120 --> 00:02:44.790
its early presence alone doesn't


00:02:44.800 --> 00:02:47.790
guarantee that life emerged during this


00:02:47.800 --> 00:02:51.070
period nevertheless This research opens


00:02:51.080 --> 00:02:53.350
up exciting new possibilities about the


00:02:53.360 --> 00:02:54.949
conditions present in the infant


00:02:54.959 --> 00:02:57.470
universe and challenges us to reconsider


00:02:57.480 --> 00:03:00.949
our assumptions about Cosmic evolution


00:03:00.959 --> 00:03:03.229
next up in today's news rocket lab is


00:03:03.239 --> 00:03:06.070
gearing up for an exciting start to 2025


00:03:06.080 --> 00:03:07.630
with their first orbital launch of the


00:03:07.640 --> 00:03:09.550
Year scheduled from their launch complex


00:03:09.560 --> 00:03:12.270
one in Mahia New Zealand the Mission


00:03:12.280 --> 00:03:15.190
cleverly named iot for you and me is set


00:03:15.200 --> 00:03:16.949
to lift off this Sunday morning local


00:03:16.959 --> 00:03:19.550
time carrying a valuable payload of five


00:03:19.560 --> 00:03:21.229
satellites for the French Internet of


00:03:21.239 --> 00:03:22.830
Things company


00:03:22.840 --> 00:03:25.390
kise this launch marks another important


00:03:25.400 --> 00:03:27.270
step in expanding global satellite


00:03:27.280 --> 00:03:29.550
coverage for the Internet of Things each


00:03:29.560 --> 00:03:31.470
of these satellites measuring just over


00:03:31.480 --> 00:03:34.509
4 and 1/2x 5 ft will be placed into a


00:03:34.519 --> 00:03:36.869
circular orbit about 400 Mi above


00:03:36.879 --> 00:03:39.309
Earth's surface they'll be traveling at


00:03:39.319 --> 00:03:41.670
an incredible speed of nearly 5 m per


00:03:41.680 --> 00:03:43.910
second powered by Electric propulsion


00:03:43.920 --> 00:03:46.750
systems and solar panels the mission is


00:03:46.760 --> 00:03:48.750
particularly significant as it


00:03:48.760 --> 00:03:50.830
represents the fourth of five dedicated


00:03:50.840 --> 00:03:52.589
launches needed to complete kise's


00:03:52.599 --> 00:03:55.949
ambitious constellation of 25 satellites


00:03:55.959 --> 00:03:58.149
once fully deployed this network will


00:03:58.159 --> 00:04:00.069
ensure continuous data transmission with


00:04:00.079 --> 00:04:02.429
up to 80 satellite passes every day over


00:04:02.439 --> 00:04:04.910
any point on the globe the launch was


00:04:04.920 --> 00:04:06.309
originally planned for earlier this


00:04:06.319 --> 00:04:08.030
month but had to be postponed due to a


00:04:08.040 --> 00:04:09.429
potential Collision risk with the


00:04:09.439 --> 00:04:12.030
International Space Station this kind of


00:04:12.040 --> 00:04:13.550
careful coordination and safety


00:04:13.560 --> 00:04:15.149
consideration is crucial in our


00:04:15.159 --> 00:04:17.990
increasingly crowded orbital environment


00:04:18.000 --> 00:04:19.909
rocket lab continues to demonstrate its


00:04:19.919 --> 00:04:21.550
reliability in the small satellite


00:04:21.560 --> 00:04:24.070
launch market providing regular access


00:04:24.080 --> 00:04:26.189
to space for companies looking to expand


00:04:26.199 --> 00:04:27.629
their orbital


00:04:27.639 --> 00:04:29.710
infrastructure this Mission reinforced


00:04:29.720 --> 00:04:31.710
forces their position as a key player in


00:04:31.720 --> 00:04:33.830
the commercial space industry while


00:04:33.840 --> 00:04:35.590
helping to build out the global internet


00:04:35.600 --> 00:04:37.029
of things Network that will connect


00:04:37.039 --> 00:04:39.230
devices and sensors


00:04:39.240 --> 00:04:41.510
worldwide in significant news from the


00:04:41.520 --> 00:04:43.870
Aerospace industry today Boeing has


00:04:43.880 --> 00:04:45.749
issued a stark warning about the future


00:04:45.759 --> 00:04:48.189
of NASA's space launch system program


00:04:48.199 --> 00:04:49.990
during an hastily arranged six-minute


00:04:50.000 --> 00:04:52.550
meeting Boeing's vice president and SLS


00:04:52.560 --> 00:04:55.070
program manager David ducher informed


00:04:55.080 --> 00:04:57.629
approximately 800 employees that their


00:04:57.639 --> 00:05:00.029
contracts with NASA could end as soon as


00:05:00.039 --> 00:05:02.469
march with potential layoffs looming on


00:05:02.479 --> 00:05:05.390
the horizon this development comes as


00:05:05.400 --> 00:05:07.469
Boeing prepares to issue notices under


00:05:07.479 --> 00:05:09.110
the worker adjustment and retraining


00:05:09.120 --> 00:05:11.590
notification act potentially affecting


00:05:11.600 --> 00:05:15.310
around 400 positions by April 2025 the


00:05:15.320 --> 00:05:16.870
timing of this announcement aligns with


00:05:16.880 --> 00:05:18.550
the anticipated release of President


00:05:18.560 --> 00:05:20.950
Trump's budget proposal for fiscal year


00:05:20.960 --> 00:05:23.670
2026 suggesting possible major changes


00:05:23.680 --> 00:05:26.710
to NASA's heavy lift rocket program the


00:05:26.720 --> 00:05:28.830
SLS program which has been a Cornerstone


00:05:28.840 --> 00:05:30.830
of NASA's space exploration efforts


00:05:30.840 --> 00:05:33.870
since 2011 has faced ongoing scrutiny


00:05:33.880 --> 00:05:36.590
due to its high costs and delays each


00:05:36.600 --> 00:05:38.950
launch of the massive rocket costs over


00:05:38.960 --> 00:05:41.830
$2 billion not including payload or


00:05:41.840 --> 00:05:44.510
ground systems expenses while the rocket


00:05:44.520 --> 00:05:46.909
finally made its debut flight in late


00:05:46.919 --> 00:05:50.110
2022 this came years behind schedule and


00:05:50.120 --> 00:05:52.870
billions over budget what makes this


00:05:52.880 --> 00:05:55.309
situation particularly notable is the


00:05:55.319 --> 00:05:57.870
changing landscape of space launch


00:05:57.880 --> 00:05:59.909
capabilities private companies like


00:05:59.919 --> 00:06:02.629
SpaceX and blue origin have developed


00:06:02.639 --> 00:06:04.870
their own heavy lift rockets that are


00:06:04.880 --> 00:06:07.629
not only partially reusable but operate


00:06:07.639 --> 00:06:10.110
at a fraction of the sls's cost less


00:06:10.120 --> 00:06:12.830
than on10th in fact there's reportedly


00:06:12.840 --> 00:06:14.950
been significant debate within NASA and


00:06:14.960 --> 00:06:17.070
White House leadership about the future


00:06:17.080 --> 00:06:19.629
of both the SLS rocket and the broader


00:06:19.639 --> 00:06:22.629
Artemis Moon program some advocate for


00:06:22.639 --> 00:06:24.790
completing the planned Artemis 2 and 3


00:06:24.800 --> 00:06:26.670
missions using the initial version of


00:06:26.680 --> 00:06:29.230
SLS before ending the program While


00:06:29.240 --> 00:06:30.909
others argue for an immediate


00:06:30.919 --> 00:06:33.390
cancellation to prevent further cost


00:06:33.400 --> 00:06:35.950
overruns this situation highlights the


00:06:35.960 --> 00:06:38.270
ongoing evolution in space launch


00:06:38.280 --> 00:06:40.589
technology and the challenges facing


00:06:40.599 --> 00:06:42.670
traditional government contracted space


00:06:42.680 --> 00:06:44.990
programs in an era of increasing


00:06:45.000 --> 00:06:47.670
commercial competition the outcome of


00:06:47.680 --> 00:06:49.469
these developments could significantly


00:06:49.479 --> 00:06:51.550
reshape NASA's approach to deep space


00:06:51.560 --> 00:06:53.589
exploration in the coming


00:06:53.599 --> 00:06:56.950
years time for today's black hole story


00:06:56.960 --> 00:06:58.749
in fascinating news from our Cosmic


00:06:58.759 --> 00:07:01.189
neighborhood astronomers have uncovered


00:07:01.199 --> 00:07:03.150
compelling evidence of a super massive


00:07:03.160 --> 00:07:05.230
black hole lurking in the large melanic


00:07:05.240 --> 00:07:08.350
Cloud one of the Milky Way's satellite


00:07:08.360 --> 00:07:10.749
galaxies this discovery came through an


00:07:10.759 --> 00:07:13.390
unexpected Source hypervelocity Stars


00:07:13.400 --> 00:07:15.629
racing through our galaxy at incredible


00:07:15.639 --> 00:07:18.270
speeds using data from issa's Gaia


00:07:18.280 --> 00:07:20.670
spacecraft researchers found that about


00:07:20.680 --> 00:07:22.390
half of the previously identified


00:07:22.400 --> 00:07:24.430
hypervelocity stars in our galaxy can be


00:07:24.440 --> 00:07:26.790
traced back not to the Milky Way Center


00:07:26.800 --> 00:07:29.510
but to the large melanic Cloud these


00:07:29.520 --> 00:07:31.230
Stellar speedsters are traveling at up


00:07:31.240 --> 00:07:34.670
to 1,000 km/ second 10 times faster than


00:07:34.680 --> 00:07:36.909
typical Stars the research team


00:07:36.919 --> 00:07:39.230
constructed detailed models showing that


00:07:39.240 --> 00:07:40.909
these high-speed stars were likely


00:07:40.919 --> 00:07:43.550
ejected by a black hole in the LMC with


00:07:43.560 --> 00:07:46.070
a mass of around 600,000 times that of


00:07:46.080 --> 00:07:48.990
our sun this process occurs when binary


00:07:49.000 --> 00:07:50.909
star systems get too close to the black


00:07:50.919 --> 00:07:52.990
hole resulting in one star being


00:07:53.000 --> 00:07:54.950
captured while the other is violently


00:07:54.960 --> 00:07:56.869
flung away at extreme


00:07:56.879 --> 00:07:58.830
velocities further supporting this


00:07:58.840 --> 00:08:00.749
theory is a peculiar concentration of


00:08:00.759 --> 00:08:04.510
stars known as the Leo over density the


00:08:04.520 --> 00:08:06.230
researchers models show that this


00:08:06.240 --> 00:08:08.230
Stellar Gathering is consistent with


00:08:08.240 --> 00:08:10.830
stars ejected from the LMC by its hidden


00:08:10.840 --> 00:08:13.869
black hole this discovery challenges our


00:08:13.879 --> 00:08:15.830
current understanding of dwarf galaxies


00:08:15.840 --> 00:08:17.909
like the LMC which weren't thought to


00:08:17.919 --> 00:08:20.869
Harbor such massive black holes this


00:08:20.879 --> 00:08:23.070
finding has significant implications for


00:08:23.080 --> 00:08:25.710
our understanding of Galaxy Evolution if


00:08:25.720 --> 00:08:27.230
astronomers have been missing black


00:08:27.240 --> 00:08:30.110
holes in smaller galaxies like the LMC


00:08:30.120 --> 00:08:32.350
our theories about how galaxies grow and


00:08:32.360 --> 00:08:35.269
develop may need substantial revision it


00:08:35.279 --> 00:08:36.870
also demonstrates how the motion of


00:08:36.880 --> 00:08:39.230
entire galaxies can influence the


00:08:39.240 --> 00:08:41.790
dramatic Stellar ejections we observe


00:08:41.800 --> 00:08:43.670
adding another layer of complexity to


00:08:43.680 --> 00:08:45.190
our Cosmic


00:08:45.200 --> 00:08:47.350
understanding an intriguing Discovery


00:08:47.360 --> 00:08:49.269
has astronomers rethinking the early


00:08:49.279 --> 00:08:51.550
history of our solar system two


00:08:51.560 --> 00:08:53.310
asteroids floating in the main asteroid


00:08:53.320 --> 00:08:55.590
belt between Mars and Jupiter might


00:08:55.600 --> 00:08:57.190
actually be ancient remnants of


00:08:57.200 --> 00:08:58.949
planetary embryos from our Cosmic


00:08:58.959 --> 00:09:01.350
neighborhood earliest days these


00:09:01.360 --> 00:09:03.710
asteroids named aspirina and Lou Allen


00:09:03.720 --> 00:09:05.470
share remarkable similarities with a


00:09:05.480 --> 00:09:07.269
rare group of meteorites called angrites


00:09:07.279 --> 00:09:09.230
which are some of the oldest known rocks


00:09:09.240 --> 00:09:11.670
in our solar system this connection is


00:09:11.680 --> 00:09:13.430
particularly exciting because it could


00:09:13.440 --> 00:09:16.069
provide a direct link to the tumultuous


00:09:16.079 --> 00:09:18.389
period when our planets were first


00:09:18.399 --> 00:09:20.430
forming scientists reached this


00:09:20.440 --> 00:09:22.030
conclusion by comparing the light


00:09:22.040 --> 00:09:23.790
signatures of these asteroids with


00:09:23.800 --> 00:09:25.910
samples of angrite meteorites found on


00:09:25.920 --> 00:09:28.829
Earth the larger of the two aspirina


00:09:28.839 --> 00:09:31.630
spans about 32 m in diameter and likely


00:09:31.640 --> 00:09:33.630
represents a significant piece of a much


00:09:33.640 --> 00:09:36.350
larger ancient body possibly one that


00:09:36.360 --> 00:09:39.350
was closer in size to the moon or Mars


00:09:39.360 --> 00:09:40.949
the discovery of these potential


00:09:40.959 --> 00:09:43.310
planetary fragments offers us a unique


00:09:43.320 --> 00:09:45.430
window into the violent early days of


00:09:45.440 --> 00:09:48.590
our solar system during this period


00:09:48.600 --> 00:09:51.750
numerous planetary embryos bodies larger


00:09:51.760 --> 00:09:53.750
than asteroids but smaller than fully


00:09:53.760 --> 00:09:56.509
formed planets collided and merged as


00:09:56.519 --> 00:09:59.030
they grew into the planets we know today


00:09:59.040 --> 00:10:01.110
many were destroyed in the process


00:10:01.120 --> 00:10:03.069
leaving behind only fragments as


00:10:03.079 --> 00:10:04.550
evidence of their


00:10:04.560 --> 00:10:07.110
existence if confirmed these asteroids


00:10:07.120 --> 00:10:09.150
could be some of the last surviving


00:10:09.160 --> 00:10:11.670
pieces of long-lost Worlds preserving


00:10:11.680 --> 00:10:13.509
crucial information about how planets


00:10:13.519 --> 00:10:15.910
form and evolve their study might help


00:10:15.920 --> 00:10:17.670
us better understand not only our own


00:10:17.680 --> 00:10:19.750
solar systems history but also the


00:10:19.760 --> 00:10:21.590
process of planetary formation occurring


00:10:21.600 --> 00:10:23.590
around other


00:10:23.600 --> 00:10:25.750
stars and that brings us to the end of


00:10:25.760 --> 00:10:28.430
