00:00:00 --> 00:00:02 hello space enthusiasts today's
00:00:02 --> 00:00:03 headlines are packed with some big
00:00:03 --> 00:00:05 developments in astronomy and space
00:00:05 --> 00:00:07 exploration we've got quite a lineup for
00:00:07 --> 00:00:09 you from Mission complications that
00:00:09 --> 00:00:11 affects the International Space Station
00:00:11 --> 00:00:13 to groundbreaking discoveries that are
00:00:13 --> 00:00:15 reshaping our understanding of the
00:00:15 --> 00:00:18 cosmos we'll dive into the latest about
00:00:18 --> 00:00:21 a crucial NASA SpaceX Mission delay
00:00:21 --> 00:00:22 that's affecting two astronauts who've
00:00:22 --> 00:00:25 been waiting months to return home then
00:00:25 --> 00:00:28 we'll explore an intriguing debate or
00:00:28 --> 00:00:30 would that be a developing spat
00:00:30 --> 00:00:32 over potential Interstellar artifacts
00:00:32 --> 00:00:34 and what they might tell us about our
00:00:34 --> 00:00:36 Cosmic neighborhood get ready for an
00:00:36 --> 00:00:37 enlightening discussion about tonight's
00:00:37 --> 00:00:40 lunar eclipse and its scientific
00:00:40 --> 00:00:42 significance plus an absolutely stunning
00:00:42 --> 00:00:45 announcement about Saturn our ring giant
00:00:45 --> 00:00:47 has just gotten a lot more crowded with
00:00:47 --> 00:00:49 the discovery of over a hundred new
00:00:49 --> 00:00:52 moons we'll also unravel the mystery
00:00:52 --> 00:00:54 behind a peculiar deep space radio
00:00:54 --> 00:00:56 signal and take a fascinating look at
00:00:56 --> 00:00:58 the powerful Jets emanating from super
00:00:58 --> 00:01:00 massive black holes there's a lot to
00:01:00 --> 00:01:03 cover so let's get started a critical
00:01:03 --> 00:01:06 NASA SpaceX Mission has hit an
00:01:06 --> 00:01:07 unexpected snag at Florida's Cape
00:01:08 --> 00:01:10 Canaveral space force station where a
00:01:10 --> 00:01:11 hydraulic ground issue forced
00:01:11 --> 00:01:13 controllers to postpone the much
00:01:13 --> 00:01:16 anticipated Falcon 9 launch this delay
00:01:16 --> 00:01:17 has particularly significant
00:01:17 --> 00:01:19 implications for two NASA astronauts
00:01:19 --> 00:01:22 Sunni Williams and Butch Wilmore who
00:01:22 --> 00:01:23 have been stationed aboard the
00:01:23 --> 00:01:25 International Space Station far longer
00:01:25 --> 00:01:28 than originally planned these veteran
00:01:28 --> 00:01:30 astronauts launched into space on June
00:01:30 --> 00:01:34 5th 2024 expecting an 8-day Mission
00:01:34 --> 00:01:36 however as we well know their stay has
00:01:36 --> 00:01:38 stretched to more than 9 months after
00:01:38 --> 00:01:39 their Boeing spacecraft was deemed
00:01:39 --> 00:01:43 unsafe for return travel the postponed
00:01:43 --> 00:01:44 SpaceX mission was meant to be their
00:01:44 --> 00:01:47 ticket home potentially allowing them to
00:01:47 --> 00:01:50 return to Earth as early as Sunday the
00:01:50 --> 00:01:51 specific issue involved one of the
00:01:51 --> 00:01:54 launchpads clamp arms with Engineers
00:01:54 --> 00:01:55 expressing concerns that it wouldn't
00:01:55 --> 00:01:58 open fully during launch while there's
00:01:58 --> 00:01:59 another potential launch window
00:01:59 --> 00:02:02 available tomorrow SpaceX hasn't yet
00:02:02 --> 00:02:03 confirmed whether the equipment will be
00:02:03 --> 00:02:06 ready in time despite their Extended
00:02:06 --> 00:02:08 Stay both Williams and Wilmore have
00:02:08 --> 00:02:10 maintained remarkable composure about
00:02:10 --> 00:02:13 their situation during a September news
00:02:13 --> 00:02:16 conference from the ISS they emphasized
00:02:16 --> 00:02:19 their training to expect the unexpected
00:02:19 --> 00:02:22 Williams age 58 even referred to the
00:02:22 --> 00:02:25 space station as her happy place though
00:02:25 --> 00:02:26 she admitted to missing her family and
00:02:26 --> 00:02:30 two dogs back on Earth Wilmore 61
00:02:30 --> 00:02:32 acknowledged their decision not to
00:02:32 --> 00:02:34 return on the Starliner spacecraft they
00:02:34 --> 00:02:36 arrived in noting they weren't
00:02:36 --> 00:02:37 comfortable with that option given the
00:02:37 --> 00:02:40 technical issues he highlighted that 90%
00:02:40 --> 00:02:42 of their training focused on preparing
00:02:42 --> 00:02:45 for unexpected situations and they're
00:02:45 --> 00:02:46 willing to remain in orbit for as long
00:02:46 --> 00:02:50 as necessary to ensure a safe return the
00:02:50 --> 00:02:52 extended Mission has given Williams
00:02:52 --> 00:02:53 additional perspective on our home
00:02:53 --> 00:02:57 planet as she poignantly noted being in
00:02:57 --> 00:02:59 space has opened her mind to thinking
00:02:59 --> 00:03:00 differently about Earth Earth
00:03:00 --> 00:03:03 emphasizing that it's the one planet we
00:03:03 --> 00:03:05 have and we should be taking care of
00:03:05 --> 00:03:08 it now an update to a story we brought
00:03:08 --> 00:03:11 you yesterday an intriguing scientific
00:03:11 --> 00:03:13 debate has erupted in the astronomical
00:03:13 --> 00:03:15 Community centered around Harvard
00:03:15 --> 00:03:17 physicist AI lob's bold claims about
00:03:17 --> 00:03:19 metallic spheral recovered from the
00:03:19 --> 00:03:22 seafloor near Papua New Guinea lob
00:03:22 --> 00:03:24 suggests these tiny fragments might not
00:03:24 --> 00:03:27 just be from space but potentially from
00:03:27 --> 00:03:29 an Interstellar source and more cont
00:03:29 --> 00:03:32 controversially could be evidence of an
00:03:32 --> 00:03:35 alien civilization from another star
00:03:35 --> 00:03:38 system as we reported yesterday The
00:03:38 --> 00:03:39 Story begins with a meteor that blazed
00:03:39 --> 00:03:41 across the South Pacific Ocean on
00:03:41 --> 00:03:44 January 8th 2014 tracked by the US
00:03:44 --> 00:03:45 Department of
00:03:45 --> 00:03:48 Defense last year L led a mission to
00:03:48 --> 00:03:50 recover fragments from this object but
00:03:50 --> 00:03:52 his findings have met with significant
00:03:52 --> 00:03:55 skepticism from the scientific Community
00:03:55 --> 00:03:57 a team led by John's Hopkins University
00:03:57 --> 00:03:59 researchers has particularly challenged
00:03:59 --> 00:04:02 the evidence suggesting that what was
00:04:02 --> 00:04:03 thought to be seismic data from the
00:04:03 --> 00:04:05 meteorites impact was actually caused by
00:04:05 --> 00:04:08 something far more mundane a truck
00:04:08 --> 00:04:10 passing by the seismic station on Manis
00:04:10 --> 00:04:13 Island however lob maintains that the
00:04:13 --> 00:04:15 expedition's location was determined
00:04:15 --> 00:04:17 primarily by NASA's Center for neear
00:04:17 --> 00:04:19 object studies calculations of the
00:04:19 --> 00:04:23 meteor's trajectory not the seismic data
00:04:23 --> 00:04:24 the controversy deepens when it comes to
00:04:24 --> 00:04:26 the composition of these recovered
00:04:26 --> 00:04:29 spheral while L's team argues that their
00:04:29 --> 00:04:30 chemical IAL analysis rules out
00:04:31 --> 00:04:33 earth-based contamination other
00:04:33 --> 00:04:35 physicists contend that the only
00:04:35 --> 00:04:37 definitive proof of interstellar origin
00:04:37 --> 00:04:39 would come from dating the material and
00:04:39 --> 00:04:43 finding it to be older than our son this
00:04:43 --> 00:04:45 debate highlights a fundamental tension
00:04:45 --> 00:04:46 in the search for extraterrestrial
00:04:46 --> 00:04:49 evidence the challenge of distinguishing
00:04:49 --> 00:04:51 truly exotic materials from more
00:04:51 --> 00:04:54 conventional explanations the scientific
00:04:54 --> 00:04:56 Community continues to scrutinize these
00:04:56 --> 00:04:58 findings emphasizing the importance of
00:04:58 --> 00:05:00 rigorous verification
00:05:00 --> 00:05:02 before making extraordinary claims about
00:05:02 --> 00:05:04 potential alien
00:05:04 --> 00:05:07 artifacts and here's another update and
00:05:07 --> 00:05:10 reminder get ready for a spectacular
00:05:10 --> 00:05:12 Celestial show coming up tonight March
00:05:12 --> 00:05:14 13th into the early morning hours of
00:05:14 --> 00:05:16 March 14th as we'll witness a total
00:05:16 --> 00:05:19 lunar eclipse during this event our moon
00:05:19 --> 00:05:21 will pass through Earth's Shadow
00:05:21 --> 00:05:23 transforming from its usual bright white
00:05:23 --> 00:05:26 glow to an eerie reddish Hue earning it
00:05:26 --> 00:05:29 the popular nickname blood moon but but
00:05:29 --> 00:05:31 this isn't just a pretty light show in
00:05:31 --> 00:05:33 the sky these eclipses have been
00:05:33 --> 00:05:35 teaching us about our world since
00:05:35 --> 00:05:37 ancient times in fact it was ancient
00:05:37 --> 00:05:39 Greek philosophers who first realized
00:05:39 --> 00:05:41 Earth must be round by observing the
00:05:41 --> 00:05:43 curved Shadow It cast on the moon during
00:05:43 --> 00:05:46 eclipses one of Humanity's earliest
00:05:46 --> 00:05:47 scientific breakthroughs from watching
00:05:47 --> 00:05:50 these events today lunar eclipses
00:05:51 --> 00:05:53 continue to be valuable scientific tools
00:05:53 --> 00:05:55 particularly for studying Earth's
00:05:55 --> 00:05:57 atmosphere that distinctive red color we
00:05:57 --> 00:05:59 see during totality happens because
00:05:59 --> 00:06:01 sunlight bends through our atmosphere
00:06:01 --> 00:06:03 before reaching the moon our atmosphere
00:06:03 --> 00:06:05 filters out blues and greens letting
00:06:05 --> 00:06:08 mostly red light through the same
00:06:08 --> 00:06:09 process that gives us those gorgeous
00:06:09 --> 00:06:11 sunset colors the moon's appearance
00:06:11 --> 00:06:13 during eclipses can actually tell us
00:06:13 --> 00:06:16 about what's happening in our atmosphere
00:06:16 --> 00:06:17 sometimes it appears bright red while
00:06:18 --> 00:06:19 other times it takes on a darker
00:06:19 --> 00:06:21 brownish gray color especially after
00:06:21 --> 00:06:23 major volcanic eruptions that have added
00:06:23 --> 00:06:24 particles to our
00:06:25 --> 00:06:26 atmosphere these events are also
00:06:26 --> 00:06:29 providing insights about the moon itself
00:06:29 --> 00:06:31 NASA's lunar reconnaissance Orbiter has
00:06:32 --> 00:06:33 made fascinating discoveries during
00:06:33 --> 00:06:36 previous eclipses revealing that the
00:06:36 --> 00:06:38 lunar surface doesn't cool uniformly
00:06:38 --> 00:06:41 when it enters Earth's Shadow these
00:06:41 --> 00:06:43 temperature variations tell us about
00:06:43 --> 00:06:45 differences in the moon surface
00:06:45 --> 00:06:48 properties that we might otherwise Miss
00:06:48 --> 00:06:50 what makes lunar eclipses particularly
00:06:50 --> 00:06:51 special is their
00:06:51 --> 00:06:54 accessibility unlike solar eclipses that
00:06:54 --> 00:06:56 are only visible along a narrow path
00:06:56 --> 00:06:58 lunar eclipses can be seen by everyone
00:06:58 --> 00:07:01 on the night side of Earth this upcoming
00:07:01 --> 00:07:02 Eclipse will be visible to more than a
00:07:02 --> 00:07:04 billion people and if you're watching
00:07:04 --> 00:07:07 keep your eyes peeled during a 2019
00:07:07 --> 00:07:09 Eclipse observers even caught glimpse of
00:07:10 --> 00:07:12 a meteor impact on the lunar
00:07:12 --> 00:07:15 surface in an extraordinary astronomical
00:07:15 --> 00:07:17 Discovery an international team of
00:07:17 --> 00:07:20 researchers has found 128 new moons
00:07:20 --> 00:07:22 orbiting Saturn dramatically expanding
00:07:22 --> 00:07:24 our understanding of the ringed planet
00:07:24 --> 00:07:27 satellite system this breakthrough
00:07:27 --> 00:07:28 confirmed by the minor planet center
00:07:28 --> 00:07:30 just days ago
00:07:30 --> 00:07:32 makes Saturn the Undisputed champion of
00:07:32 --> 00:07:34 moons in our solar system with a total
00:07:34 --> 00:07:38 of 274 known natural satellites the team
00:07:38 --> 00:07:40 made these discoveries using the Canada
00:07:40 --> 00:07:42 France Hawaii telescope conducting
00:07:42 --> 00:07:45 observations between 2019 and
00:07:45 --> 00:07:47 2021 they employed an Innovative
00:07:47 --> 00:07:49 technique of combining multiple images
00:07:49 --> 00:07:51 to reduce noise and strengthen the
00:07:51 --> 00:07:53 signals from these previously undetected
00:07:53 --> 00:07:56 moons initially they found 64 new moons
00:07:56 --> 00:07:58 but follow-up observations in 2023
00:07:58 --> 00:08:00 revealed even more
00:08:00 --> 00:08:02 what's particularly fascinating about
00:08:02 --> 00:08:04 these new moons is that they're all
00:08:04 --> 00:08:06 irregular moons following wide
00:08:06 --> 00:08:09 elliptical orbits that are often highly
00:08:09 --> 00:08:12 inclined unlike regular moons such as
00:08:12 --> 00:08:14 our own Moon which formed alongside
00:08:14 --> 00:08:16 their parent Planet these irregular
00:08:16 --> 00:08:18 moons were likely captured by Saturn's
00:08:18 --> 00:08:21 gravity even more intriguingly
00:08:21 --> 00:08:23 scientists believe these moons are
00:08:23 --> 00:08:24 actually fragments from violent
00:08:24 --> 00:08:26 collisions that occurred in Saturn's
00:08:26 --> 00:08:29 past the majority of these newly
00:08:29 --> 00:08:31 discovered moons are clustered near
00:08:31 --> 00:08:33 what's known as the mundari group
00:08:33 --> 00:08:35 suggesting this region was the sight of
00:08:35 --> 00:08:37 a significant Collision within the last
00:08:37 --> 00:08:40 100 million years this finding adds
00:08:40 --> 00:08:42 weight to the theory that Saturn's
00:08:42 --> 00:08:44 complex system of moons and Rings is
00:08:44 --> 00:08:46 constantly evolving through a series of
00:08:46 --> 00:08:49 cosmic crashes and gravitational
00:08:49 --> 00:08:51 interactions Dr Edward Ashton who led
00:08:51 --> 00:08:54 the research suggests that Jupiter which
00:08:54 --> 00:08:58 currently has 95 confirmed moons will
00:08:58 --> 00:09:00 likely never catch up to Saturn's
00:09:00 --> 00:09:03 impressive count this discovery not only
00:09:03 --> 00:09:05 cements Saturn's position as the planet
00:09:05 --> 00:09:07 with the most moons but also provides
00:09:07 --> 00:09:09 valuable insights into how planetary
00:09:10 --> 00:09:12 systems evolve and interact over
00:09:12 --> 00:09:14 millions of years for now these new
00:09:14 --> 00:09:17 moons are identified by number sequences
00:09:17 --> 00:09:18 but they'll eventually receive proper
00:09:18 --> 00:09:20 names following the tradition of naming
00:09:20 --> 00:09:23 Saturn's moons after Norse GAC and
00:09:23 --> 00:09:26 Canadian Inuit Gods with this discovery
00:09:26 --> 00:09:28 Saturn now hosts almost twice as many
00:09:28 --> 00:09:30 moons as all other planets in our solar
00:09:30 --> 00:09:32 system combined truly making it the king
00:09:32 --> 00:09:34 of moons in our Cosmic
00:09:34 --> 00:09:36 neighborhood in another fascinating
00:09:36 --> 00:09:38 breakthrough in space science
00:09:38 --> 00:09:40 astronomers have finally cracked the
00:09:40 --> 00:09:42 case of a mysterious repeating radio
00:09:42 --> 00:09:44 signal that has puzzled researchers
00:09:44 --> 00:09:47 since its Discovery last year the signal
00:09:47 --> 00:09:49 which pulses every two hours like
00:09:49 --> 00:09:51 clockwork has been traced back to an
00:09:51 --> 00:09:54 unusual binary star system located about
00:09:54 --> 00:09:57 1 light years away in the direction
00:09:57 --> 00:10:00 of the Big Dipper this Cosmic Duo
00:10:00 --> 00:10:02 consists of a white dwarf the dense
00:10:02 --> 00:10:05 remnant of a dead star and its companion
00:10:05 --> 00:10:08 a red dwarf star what makes this
00:10:08 --> 00:10:10 discovery particularly exciting is that
00:10:10 --> 00:10:12 it represents an entirely new source for
00:10:12 --> 00:10:14 these types of long period radio bursts
00:10:15 --> 00:10:16 which were previously only associated
00:10:16 --> 00:10:18 with neutron stars the signal first
00:10:19 --> 00:10:20 appeared in data collected by the low
00:10:20 --> 00:10:23 frequency array or low far back in
00:10:23 --> 00:10:26 2015 after its initial detection
00:10:26 --> 00:10:28 researchers found six more Pulses from
00:10:28 --> 00:10:30 the same source these radio flashes can
00:10:30 --> 00:10:32 last anywhere from several seconds to a
00:10:32 --> 00:10:34 few minutes but they maintain that
00:10:34 --> 00:10:37 precise 2hour regularity that caught
00:10:37 --> 00:10:39 astronomer's attention the team's
00:10:39 --> 00:10:41 detailed follow-up observations using
00:10:41 --> 00:10:43 the multiple mirror telescope in Arizona
00:10:43 --> 00:10:46 and the McDonald observatory in Texas
00:10:46 --> 00:10:47 revealed that these two stars are locked
00:10:47 --> 00:10:50 in an incredibly tight orbital dance
00:10:50 --> 00:10:52 circling each other every
00:10:52 --> 00:10:55 125.5 minutes the interaction between
00:10:55 --> 00:10:57 their magnetic fields appears to be the
00:10:57 --> 00:10:59 source of these radio pulses as they
00:10:59 --> 00:11:02 slam together during their Cosmic Walts
00:11:02 --> 00:11:04 what's particularly intriguing about
00:11:04 --> 00:11:06 this system is that while it shares some
00:11:06 --> 00:11:08 similarities with fast radio bursts or
00:11:08 --> 00:11:10 FBS these pulses are distinctly
00:11:10 --> 00:11:13 different they have lower energy levels
00:11:13 --> 00:11:15 and last much longer than typical FBS
00:11:15 --> 00:11:17 which usually flash for just
00:11:17 --> 00:11:19 milliseconds this discovery opens up new
00:11:19 --> 00:11:20 possibilities for understanding the
00:11:21 --> 00:11:23 variety of radio signals we detect from
00:11:23 --> 00:11:25 space and suggests there might be many
00:11:25 --> 00:11:28 more such systems waiting to be found
00:11:28 --> 00:11:30 this breakthrough not only solves a
00:11:30 --> 00:11:32 compelling Cosmic mystery but also
00:11:32 --> 00:11:34 provides astronomers with a new category
00:11:34 --> 00:11:37 of objects to study as they work to
00:11:37 --> 00:11:38 understand the complex interactions
00:11:38 --> 00:11:41 between stars in binary systems the team
00:11:41 --> 00:11:43 is now planning to study the system's
00:11:43 --> 00:11:45 high energy ultraviolet emissions which
00:11:46 --> 00:11:47 could reveal even more details about
00:11:47 --> 00:11:50 this fascinating Stellar
00:11:50 --> 00:11:52 partnership next let's dive into some
00:11:52 --> 00:11:54 groundbreaking research about super
00:11:54 --> 00:11:56 massive black holes and their incredible
00:11:56 --> 00:11:59 Cosmic fountains nearly every large
00:11:59 --> 00:12:01 large Galaxy in our universe Harbors one
00:12:01 --> 00:12:03 of these Cosmic Giants at its Center
00:12:03 --> 00:12:05 including our own Milky Way with its
00:12:05 --> 00:12:08 black hole Sagittarius A star these
00:12:08 --> 00:12:10 objects are the densest known in the
00:12:10 --> 00:12:12 universe with masses that can reach
00:12:12 --> 00:12:15 billions of times that of our sun what's
00:12:15 --> 00:12:17 particularly fascinating is what happens
00:12:17 --> 00:12:21 when these sleeping Giants wake up when
00:12:21 --> 00:12:23 a neighboring Galaxy supplies fresh gas
00:12:23 --> 00:12:26 and dust these black holes spring into
00:12:26 --> 00:12:28 action but it's far from a peaceful
00:12:28 --> 00:12:30 process
00:12:30 --> 00:12:32 as they consume this Cosmic material it
00:12:32 --> 00:12:34 becomes superheated to temperatures
00:12:34 --> 00:12:35 millions of degrees hotter than our
00:12:35 --> 00:12:38 sun's surface this superheated matter
00:12:38 --> 00:12:40 doesn't just disappear quietly it gets
00:12:40 --> 00:12:42 ejected from the Galaxy at speeds
00:12:42 --> 00:12:44 approaching that of light creating
00:12:44 --> 00:12:47 spectacular jets that resemble enormous
00:12:47 --> 00:12:49 Cosmic fountains these high-speed plasma
00:12:49 --> 00:12:52 Jets produce radio signals that we can
00:12:52 --> 00:12:55 detect with powerful telescopes earning
00:12:55 --> 00:12:57 their host galaxies the name radio
00:12:57 --> 00:12:59 galaxies but here's the thing
00:13:00 --> 00:13:01 while black holes are common radio
00:13:01 --> 00:13:04 galaxies are relatively rare making up
00:13:04 --> 00:13:07 only about 10 to 20% of all galaxies
00:13:07 --> 00:13:09 even more exceptional are the giant
00:13:09 --> 00:13:12 radio galaxies which represent just 5%
00:13:12 --> 00:13:15 of all radio galaxies these Cosmic
00:13:15 --> 00:13:17 behemoths can produce Jets stretching an
00:13:17 --> 00:13:19 astounding 16 million light years that's
00:13:20 --> 00:13:21 nearly six times the distance between
00:13:21 --> 00:13:23 our galaxy and Andromeda the largest
00:13:23 --> 00:13:26 known jet spans an incredible 22 million
00:13:26 --> 00:13:28 light years Recent research using
00:13:28 --> 00:13:30 sophisticated computer simulations has
00:13:30 --> 00:13:32 helped us understand how these massive
00:13:32 --> 00:13:34 structures form and evolve by creating
00:13:34 --> 00:13:36 models that follow the fundamental laws
00:13:36 --> 00:13:38 of physics scientists can now track how
00:13:38 --> 00:13:40 these Jets develop over hundreds of
00:13:40 --> 00:13:42 millions of years something we could
00:13:42 --> 00:13:44 never observe directly in real time
00:13:44 --> 00:13:46 these simulations suggest that these
00:13:46 --> 00:13:48 Cosmic fountains play a crucial role in
00:13:48 --> 00:13:50 maintaining the balance of our universe
00:13:50 --> 00:13:52 preventing Galaxy clusters from
00:13:52 --> 00:13:54 collapsing under their own Gravity by
00:13:54 --> 00:13:56 heating the surrounding gas the most
00:13:56 --> 00:13:59 exciting part scientists believe there
00:13:59 --> 00:14:01 could be thousands more giant radio
00:14:01 --> 00:14:04 galaxies yet to be discovered thanks to
00:14:04 --> 00:14:07 powerful telescopes like mircat and loar
00:14:07 --> 00:14:09 combined with Advanced supercomputing
00:14:09 --> 00:14:11 capabilities we're continuing to uncover
00:14:11 --> 00:14:13 new secrets about these fascinating
00:14:13 --> 00:14:15 Cosmic
00:14:15 --> 00:14:17 phenomena and that brings us to the end
