00:00:00 --> 00:00:02 welcome to astronomy daily your source
00:00:02 --> 00:00:04 for the latest space and astronomy news
00:00:04 --> 00:00:06 I'm Anna and today we've got a
00:00:06 --> 00:00:08 fascinating lineup of stories from new
00:00:08 --> 00:00:10 discoveries about Uranus's magnetic
00:00:10 --> 00:00:13 field to upcoming space missions and
00:00:13 --> 00:00:14 Celestial
00:00:14 --> 00:00:17 phenomena scientists have just revealed
00:00:17 --> 00:00:19 a fascinating discovery about Uranus
00:00:19 --> 00:00:21 that's forcing us to rethink what we
00:00:21 --> 00:00:23 thought we knew about this mysterious
00:00:23 --> 00:00:26 ice giant it turns out that much of our
00:00:26 --> 00:00:27 understanding of the planet's magnetic
00:00:27 --> 00:00:30 field has been based on observ made
00:00:30 --> 00:00:32 during some rather unusual
00:00:32 --> 00:00:35 circumstances back in 1986 when NASA's
00:00:35 --> 00:00:38 Voyager 2 spacecraft conducted its
00:00:38 --> 00:00:40 historic flyby of Uranus it encountered
00:00:41 --> 00:00:42 the planet during what we now know was
00:00:42 --> 00:00:45 an intense solar wind event this timing
00:00:45 --> 00:00:47 couldn't have been more unfortunate from
00:00:47 --> 00:00:49 a scientific perspective as the solar
00:00:49 --> 00:00:52 wind that stream of charged particles
00:00:52 --> 00:00:54 flowing from the Sun had actually
00:00:54 --> 00:00:56 compressed Uranus's magnetic field to
00:00:56 --> 00:00:59 just 1 of its normal size according to
00:00:59 --> 00:01:01 new research published in nature
00:01:01 --> 00:01:03 astronomy these conditions only occur
00:01:03 --> 00:01:07 about 4% of the time if Voyager 2 had
00:01:07 --> 00:01:09 arrived just a week earlier we would
00:01:09 --> 00:01:10 have seen a completely different picture
00:01:10 --> 00:01:13 of Uranus's magnetosphere the protective
00:01:13 --> 00:01:16 magnetic bubble surrounding the planet
00:01:16 --> 00:01:17 this discovery has significant
00:01:17 --> 00:01:19 implications for our understanding of
00:01:19 --> 00:01:23 Uranus's moons particularly Titania and
00:01:23 --> 00:01:25 Oberon previously scientists thought
00:01:25 --> 00:01:27 these moons often orbited outside the
00:01:27 --> 00:01:30 planet's protective magnetosphere
00:01:30 --> 00:01:31 now it appears they typically remain
00:01:31 --> 00:01:33 within this magnetic Shield which could
00:01:33 --> 00:01:35 make it easier for researchers to detect
00:01:36 --> 00:01:38 potential subsurface oceans on these
00:01:38 --> 00:01:40 moons the findings also suggest that
00:01:40 --> 00:01:43 Uranus's magnetosphere is actually quite
00:01:43 --> 00:01:44 similar to those of our other giant
00:01:44 --> 00:01:48 planets Jupiter Saturn and Neptune this
00:01:48 --> 00:01:51 Revelation helps paint a more coherent
00:01:51 --> 00:01:53 picture of how magnetic fields work in
00:01:53 --> 00:01:56 the outer solar system scientists are
00:01:56 --> 00:01:58 now emphasizing The crucial need for a
00:01:58 --> 00:02:01 dedicated mission to Uranus to better
00:02:01 --> 00:02:04 understand not only its magnetic field
00:02:04 --> 00:02:07 but also its atmosphere rings and
00:02:07 --> 00:02:10 fascinating collection of moons such a
00:02:10 --> 00:02:12 mission would help us fill in the many
00:02:12 --> 00:02:13 remaining gaps in our knowledge about
00:02:13 --> 00:02:15 this distant ice
00:02:15 --> 00:02:18 giant next another mystery moves closer
00:02:18 --> 00:02:20 to a solution in a breakthrough
00:02:20 --> 00:02:21 Discovery astronomers have made
00:02:21 --> 00:02:23 significant progress in solving one of
00:02:23 --> 00:02:26 spaces most intriguing Mysteries the
00:02:26 --> 00:02:30 origin of fast radio bursts or FBS
00:02:30 --> 00:02:31 these incredibly energetic pulses of
00:02:31 --> 00:02:33 radio frequency light have been puzzling
00:02:33 --> 00:02:35 scientists since their first detection
00:02:35 --> 00:02:39 in 2007 but now we're getting closer to
00:02:39 --> 00:02:41 understanding their Source new research
00:02:41 --> 00:02:43 published in nature reveals that these
00:02:43 --> 00:02:44 Cosmic phenomena are more likely to
00:02:45 --> 00:02:47 occur in large active galaxies rather
00:02:47 --> 00:02:49 than smaller ones the study utilized
00:02:49 --> 00:02:51 data from the Owens Valley radio
00:02:51 --> 00:02:53 Observatory where scientists detected
00:02:53 --> 00:02:56 and analy 70 FBS successfully tracking
00:02:56 --> 00:02:58 down their host
00:02:58 --> 00:03:00 galaxies what makes this Discovery
00:03:00 --> 00:03:01 particularly interesting is the
00:03:01 --> 00:03:04 connection to magnetars highly
00:03:04 --> 00:03:06 magnetized neutron stars that rank among
00:03:06 --> 00:03:09 the most extreme objects in the universe
00:03:09 --> 00:03:10 the research suggests that these
00:03:10 --> 00:03:12 powerful Cosmic engines are likely
00:03:12 --> 00:03:14 responsible for generating these intense
00:03:14 --> 00:03:17 radio bursts the findings also tell us
00:03:17 --> 00:03:18 something fascinating about the
00:03:18 --> 00:03:21 environments where these events occur
00:03:21 --> 00:03:23 these larger galaxies tend to be rich in
00:03:23 --> 00:03:25 heavy Elements which astronomers refer
00:03:25 --> 00:03:28 to as Metals this abundance of heavy
00:03:28 --> 00:03:30 elements might be crucial for Magnet or
00:03:30 --> 00:03:32 formation possibly through complex
00:03:32 --> 00:03:36 processes involving binary star systems
00:03:36 --> 00:03:37 this connection to Binary stars is
00:03:37 --> 00:03:39 particularly intriguing because we know
00:03:39 --> 00:03:42 that 84% of all massive stars exist in
00:03:42 --> 00:03:45 these paired systems when these Stars
00:03:45 --> 00:03:47 merge they can create even more massive
00:03:47 --> 00:03:49 stars with stronger magnetic fields than
00:03:49 --> 00:03:51 either of the original Stars would have
00:03:51 --> 00:03:53 had individually This research not only
00:03:54 --> 00:03:56 helps us understand where FBS come from
00:03:56 --> 00:03:58 but also provides valuable insights into
00:03:58 --> 00:04:00 how magnetars form andol
00:04:00 --> 00:04:02 it's another piece of the cosmic puzzle
00:04:02 --> 00:04:05 falling into place helping us better
00:04:05 --> 00:04:07 understand the life cycles of stars and
00:04:07 --> 00:04:09 the extreme physics at play in our
00:04:09 --> 00:04:11 universe the team plans to continue
00:04:11 --> 00:04:14 their search using an even larger array
00:04:14 --> 00:04:16 planned for construction in Nevada which
00:04:16 --> 00:04:18 should help us discover even more FBS
00:04:18 --> 00:04:21 and their host galaxies by 2028
00:04:21 --> 00:04:23 potentially revealing even more secrets
00:04:23 --> 00:04:26 about these mysterious Cosmic
00:04:26 --> 00:04:28 phenomena get ready for an absolutely
00:04:28 --> 00:04:31 packed week of space space launches
00:04:31 --> 00:04:32 SpaceX is leading the charge with an
00:04:32 --> 00:04:34 impressive lineup of missions they've
00:04:35 --> 00:04:36 already kicked things off with two
00:04:36 --> 00:04:38 Launches on Monday the koreasat 6A
00:04:38 --> 00:04:40 communication satellite from Kennedy
00:04:40 --> 00:04:42 Space Center and a starlink mission
00:04:42 --> 00:04:46 carrying 24 satellites just hours later
00:04:46 --> 00:04:49 but that's just the beginning SpaceX has
00:04:49 --> 00:04:51 three more starlink missions planned
00:04:51 --> 00:04:53 this week alone launching from both
00:04:53 --> 00:04:55 coasts from California's vandenbberg
00:04:55 --> 00:04:57 base they're preparing to send up 20
00:04:57 --> 00:05:00 starlink satellites including 13
00:05:00 --> 00:05:02 specialized direct to sell satellites
00:05:02 --> 00:05:04 meanwhile over in Florida two more
00:05:04 --> 00:05:06 batches of their next Generation V2 mini
00:05:06 --> 00:05:08 satellites are getting ready for launch
00:05:08 --> 00:05:10 the company is also preparing for
00:05:10 --> 00:05:12 another major commercial Mission the
00:05:12 --> 00:05:14 Opus X satellite heading to
00:05:14 --> 00:05:16 geostationary orbit this Australian
00:05:16 --> 00:05:18 Communications satellite launch is
00:05:18 --> 00:05:20 scheduled for Sunday from Kennedy Space
00:05:20 --> 00:05:22 Center marking spacex's seventh launch
00:05:22 --> 00:05:25 attempt of just this week over in China
00:05:25 --> 00:05:27 space activities are ramping up as well
00:05:27 --> 00:05:28 they're preparing for two significant
00:05:28 --> 00:05:30 launches the first is a mysterious
00:05:30 --> 00:05:33 payload heading up on a long march 4C
00:05:33 --> 00:05:35 rocket from their Taiwan launch Center
00:05:35 --> 00:05:37 but perhaps more notably they're getting
00:05:37 --> 00:05:39 ready to send the tanjo 8 cargo
00:05:39 --> 00:05:41 spacecraft to their tiangong space
00:05:41 --> 00:05:43 station this critical resupply Mission
00:05:43 --> 00:05:47 will launch on a Long March 7th rocket
00:05:47 --> 00:05:49 from wenchong delivering essential
00:05:49 --> 00:05:51 supplies to the crew currently aboard
00:05:51 --> 00:05:53 the station if all these launches go
00:05:53 --> 00:05:55 according to plan we're looking at
00:05:55 --> 00:05:57 potentially eight successful orbital
00:05:57 --> 00:06:00 missions in just seven days a remarkable
00:06:00 --> 00:06:02 demonstration of how routine space
00:06:02 --> 00:06:06 access has become in our modern era next
00:06:06 --> 00:06:07 up some new Research into a star that's
00:06:07 --> 00:06:10 very dear to us in fascinating new
00:06:10 --> 00:06:11 research from the national Center for
00:06:11 --> 00:06:14 atmospheric research scientists have
00:06:14 --> 00:06:16 discovered that our sun likely has polar
00:06:16 --> 00:06:18 vortices similar to those we see on
00:06:18 --> 00:06:19 Earth and other planets in our solar
00:06:20 --> 00:06:22 system but there's a crucial difference
00:06:22 --> 00:06:24 while Earth's vortices are shaped by
00:06:24 --> 00:06:26 atmospheric conditions the suns are
00:06:27 --> 00:06:29 controlled by powerful magnetic fields
00:06:29 --> 00:06:31 these solar vortices appear to form in a
00:06:31 --> 00:06:35 tight ring around 55° latitude
00:06:35 --> 00:06:37 comparable to Earth's Arctic Circle
00:06:37 --> 00:06:40 what's particularly interesting is how
00:06:40 --> 00:06:43 they behave throughout the sun's cycle
00:06:43 --> 00:06:45 the vortices move toward the poles in a
00:06:45 --> 00:06:47 continuously tightening ring
00:06:47 --> 00:06:49 occasionally breaking off smaller
00:06:49 --> 00:06:52 vortices as they go eventually they
00:06:52 --> 00:06:54 settle into just two vortices at the
00:06:54 --> 00:06:55 poles before disappearing completely
00:06:56 --> 00:06:57 during solar
00:06:57 --> 00:06:59 maximum the strength of the solar cycle
00:06:59 --> 00:07:01 appears to directly influence how these
00:07:01 --> 00:07:04 vortices form and move this discovery
00:07:04 --> 00:07:05 could be revolutionary for our
00:07:06 --> 00:07:07 understanding of solar Behavior but
00:07:07 --> 00:07:10 there's a catch we've never actually
00:07:10 --> 00:07:12 observed these vortices directly all of
00:07:12 --> 00:07:13 our current knowledge comes from
00:07:13 --> 00:07:16 computer simulations as we've never sent
00:07:16 --> 00:07:18 a mission capable of viewing the sun's
00:07:18 --> 00:07:20 poles This research could have
00:07:20 --> 00:07:22 significant practical applications
00:07:22 --> 00:07:24 particularly for space weather
00:07:24 --> 00:07:26 forecasting understanding these polar
00:07:26 --> 00:07:27 vortices and their relationship to the
00:07:28 --> 00:07:30 sun's magnetic field might help us
00:07:30 --> 00:07:32 better predict solar events that can
00:07:32 --> 00:07:34 impact our satellites and power grids
00:07:34 --> 00:07:36 here on Earth the findings are also
00:07:36 --> 00:07:38 timely as they could help guide future
00:07:38 --> 00:07:41 solar missions the research suggests
00:07:41 --> 00:07:43 that these vortices should be observable
00:07:43 --> 00:07:45 during most parts of the solar cycle
00:07:45 --> 00:07:47 except during solar maximum this
00:07:47 --> 00:07:49 information could be crucial for
00:07:49 --> 00:07:51 planning when to launch future polar
00:07:51 --> 00:07:53 observation missions to ensure we get
00:07:53 --> 00:07:55 the most valuable data
00:07:55 --> 00:07:58 possible in an unexpected twist for
00:07:58 --> 00:08:00 space research Master students at Neman
00:08:00 --> 00:08:02 University have made a remarkable
00:08:02 --> 00:08:04 prediction about the European space
00:08:04 --> 00:08:07 agency's upcoming Lisa Mission their
00:08:07 --> 00:08:08 models suggest that when this
00:08:08 --> 00:08:10 space-based gravitational wave detector
00:08:10 --> 00:08:13 launches in the mid 2030s it might pick
00:08:13 --> 00:08:15 up something surprising gravitational
00:08:15 --> 00:08:17 waves from white dwarf stars that are
00:08:17 --> 00:08:19 actually stronger than those from black
00:08:19 --> 00:08:21 holes this finding has caught many
00:08:21 --> 00:08:24 astronomers offu as the original Mission
00:08:24 --> 00:08:26 planning hadn't fully accounted for this
00:08:26 --> 00:08:28 potential noise from white dwarfs but
00:08:28 --> 00:08:30 what might initially seem like an
00:08:30 --> 00:08:32 obstacle could actually turn out to be a
00:08:32 --> 00:08:34 fascinating opportunity for new
00:08:34 --> 00:08:37 discoveries what makes this particularly
00:08:37 --> 00:08:38 exciting is that it could give us a
00:08:38 --> 00:08:40 completely new way to study Stellar
00:08:40 --> 00:08:43 evolution in distant galaxies while our
00:08:43 --> 00:08:44 current telescopes can only observe
00:08:44 --> 00:08:47 white dwarfs within our own Milky Way
00:08:47 --> 00:08:49 Lisa's ability to detect gravitational
00:08:49 --> 00:08:51 waves could let us listen in on white
00:08:51 --> 00:08:53 dwarfs in other galaxies effectively
00:08:53 --> 00:08:56 giving us a new window into the cosmic
00:08:56 --> 00:08:58 neighborhood the research teams have
00:08:58 --> 00:08:59 found that while this white DWF signal
00:09:00 --> 00:09:02 might be stronger than expected it can
00:09:02 --> 00:09:04 be filtered out from the data this means
00:09:04 --> 00:09:06 we won't lose any of Lisa's ability to
00:09:06 --> 00:09:09 detect other fascinating phenomena and
00:09:09 --> 00:09:11 we gain an additional tool for
00:09:11 --> 00:09:13 understanding these dense Stellar
00:09:13 --> 00:09:15 remnants this discovery really
00:09:15 --> 00:09:16 highlights how space research can
00:09:16 --> 00:09:19 surprise us even before its launch Lisa
00:09:19 --> 00:09:21 is already challenging our assumptions
00:09:21 --> 00:09:23 and promising to deliver not just what
00:09:23 --> 00:09:26 we're looking for but potentially even
00:09:26 --> 00:09:28 more exciting discoveries we hadn't
00:09:28 --> 00:09:29 anticipated
00:09:29 --> 00:09:31 it's a perfect example of how sometimes
00:09:31 --> 00:09:34 in astronomy what we initially consider
00:09:34 --> 00:09:37 interference can actually lead us to new
00:09:37 --> 00:09:40 and valuable insights about our
00:09:40 --> 00:09:43 universe here's one for lovers of uaps
00:09:43 --> 00:09:45 in Washington an important Congressional
00:09:45 --> 00:09:47 hearing is set for this Wednesday that
00:09:47 --> 00:09:49 could shed new light on one of the most
00:09:49 --> 00:09:52 intriguing topics in Aerospace the house
00:09:52 --> 00:09:54 committee on oversight and
00:09:54 --> 00:09:55 accountability will be conducting a
00:09:55 --> 00:09:58 hearing titled unidentified anomalous
00:09:58 --> 00:10:01 phenomena exposing the truth marking
00:10:01 --> 00:10:03 their second effort to examine secret
00:10:03 --> 00:10:05 UAP research programs conducted by the
00:10:05 --> 00:10:08 US government Representatives Nancy mace
00:10:08 --> 00:10:10 and Glenn grathan are leading this joint
00:10:10 --> 00:10:12 hearing arguing that Americans deserve
00:10:12 --> 00:10:14 greater transparency about what the
00:10:14 --> 00:10:15 government knows regarding these
00:10:15 --> 00:10:18 mysterious phenomena the hearing will
00:10:18 --> 00:10:19 specifically focus on the department of
00:10:20 --> 00:10:21 defense's classification policies
00:10:22 --> 00:10:24 surrounding UAP and explore ways to make
00:10:24 --> 00:10:26 this information more accessible to the
00:10:26 --> 00:10:29 public among the expert Witnesses
00:10:29 --> 00:10:32 scheduled to testify is Luis elzando a
00:10:32 --> 00:10:34 former Counter Intelligence officer who
00:10:34 --> 00:10:36 has made some striking claims about
00:10:36 --> 00:10:38 government knowledge of uaps the witness
00:10:38 --> 00:10:41 panel will also include Tim galet a
00:10:41 --> 00:10:43 retired Navy rear Admiral concerned
00:10:43 --> 00:10:45 about underwater anomalies journalist
00:10:45 --> 00:10:48 Michael shellenberger and Michael Gold a
00:10:48 --> 00:10:50 former NASA associate administrator who
00:10:50 --> 00:10:53 serves on NASA's independent UAP study
00:10:53 --> 00:10:55 team it's worth noting that while
00:10:55 --> 00:10:56 there's growing interest in
00:10:56 --> 00:10:58 understanding these phenomena NASA's
00:10:58 --> 00:11:00 recent independent study found no
00:11:00 --> 00:11:03 evidence of extraterrestrial Origins for
