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 your host Anna and in today's
00:00:06 --> 00:00:08 episode we'll be covering several
00:00:08 --> 00:00:11 exciting stories from across the cosmos
00:00:11 --> 00:00:12 in a groundbreaking discovery
00:00:12 --> 00:00:14 astronomers have spotted the first rocky
00:00:14 --> 00:00:17 planet orbiting a white dwarf star
00:00:17 --> 00:00:19 providing a fascinating glimpse into
00:00:19 --> 00:00:21 what might be Earth's fate billions of
00:00:21 --> 00:00:23 years from now this Frozen world located
00:00:23 --> 00:00:26 about 4 light years away managed to
00:00:26 --> 00:00:28 survive the death and expansion of its
00:00:28 --> 00:00:31 host star the planet with a mass nearly
00:00:31 --> 00:00:33 twice that of Earth now orbits a stellar
00:00:33 --> 00:00:36 Remnant the white dwarf at a distance
00:00:36 --> 00:00:38 that puts it well beyond the former
00:00:38 --> 00:00:40 Stars habitable zone it's a chilly
00:00:40 --> 00:00:42 Outpost as the white dwarf emits only a
00:00:42 --> 00:00:44 fraction of the light it once did as a
00:00:44 --> 00:00:46 normal star this discovery raises
00:00:46 --> 00:00:47 intriguing questions about our own
00:00:48 --> 00:00:50 planet's future as our sun ages and
00:00:50 --> 00:00:52 expands into a red giant before becoming
00:00:52 --> 00:00:55 a white dwarf will Earth survive some
00:00:55 --> 00:00:56 models suggest it might While others
00:00:56 --> 00:00:58 predict Earth's destruction this
00:00:58 --> 00:01:00 newfound Planet implies Earth's chances
00:01:00 --> 00:01:02 for survival could be higher than
00:01:02 --> 00:01:05 previously thought however even if our
00:01:05 --> 00:01:07 planet does survive it would likely
00:01:07 --> 00:01:09 become an inhospitable Frozen World much
00:01:09 --> 00:01:11 like this newly discovered exoplanet
00:01:11 --> 00:01:13 it's a sobering reminder of the
00:01:13 --> 00:01:15 long-term Cosmic challenges facing our
00:01:15 --> 00:01:18 home world the International Space
00:01:18 --> 00:01:20 Station has been bustling with activity
00:01:20 --> 00:01:21 lately as several crew changes have
00:01:21 --> 00:01:24 taken place most notably two Russian
00:01:24 --> 00:01:28 cosmonauts Oleg kenko and Nikolai chub
00:01:28 --> 00:01:30 recently returned to Earth after
00:01:30 --> 00:01:34 spending an incredible 374 days in space
00:01:34 --> 00:01:36 this record-breaking Mission has
00:01:36 --> 00:01:38 provided valuable data on the effects of
00:01:38 --> 00:01:39 long duration space flight on the human
00:01:39 --> 00:01:42 body meanwhile NASA is gearing up for
00:01:42 --> 00:01:44 more crew rotations in the coming days
00:01:44 --> 00:01:46 the SpaceX crew 9 mission is set to
00:01:46 --> 00:01:48 launch as soon as this weekend bringing
00:01:48 --> 00:01:51 Fresh Faces to the orbiting laboratory
00:01:51 --> 00:01:52 this constant cycling of crew members
00:01:52 --> 00:01:54 ensures that the ISS remains
00:01:54 --> 00:01:56 continuously staffed and productive
00:01:56 --> 00:01:58 another exciting development is the
00:01:58 --> 00:02:00 potential resumption of space Walks from
00:02:00 --> 00:02:02 the US segment of the station these
00:02:02 --> 00:02:04 crucial extra vehicular activities have
00:02:04 --> 00:02:06 been on hold for nearly a year due to
00:02:06 --> 00:02:09 technical issues with the space suits
00:02:09 --> 00:02:11 however NASA is working diligently to
00:02:11 --> 00:02:12 resolve these problems and get
00:02:12 --> 00:02:14 astronauts back outside the station to
00:02:14 --> 00:02:16 perform vital maintenance and upgrades
00:02:16 --> 00:02:18 these crew changes and potential space
00:02:18 --> 00:02:20 walks highlight the dynamic nature of
00:02:20 --> 00:02:21 Life aboard the International Space
00:02:21 --> 00:02:23 Station as well as the ongoing
00:02:23 --> 00:02:25 commitment to scientific research and
00:02:25 --> 00:02:28 exploration in low earth orbit related
00:02:28 --> 00:02:30 news back on the ground NASA is gearing
00:02:30 --> 00:02:32 up for the crew change over this weekend
00:02:33 --> 00:02:34 and they want you to be a part of it the

00:03:24 --> 00:03:27 Journey to the Stars let's move on to
00:03:27 --> 00:03:29 some Hubble news today in a stunning
00:03:29 --> 00:03:31 revelation the Hubble Space Telescope
00:03:31 --> 00:03:33 has unveiled an unexpected Cosmic
00:03:33 --> 00:03:35 phenomenon astronomers have discovered
00:03:35 --> 00:03:37 that the powerful jet emanating from a
00:03:37 --> 00:03:39 super massive black hole at the core of
00:03:39 --> 00:03:42 a massive Galaxy is causing nearby stars
00:03:42 --> 00:03:44 to erupt more frequently than usual this
00:03:44 --> 00:03:46 jet a blazing stream of plasma
00:03:46 --> 00:03:49 stretching over 3 Lighty years seems
00:03:49 --> 00:03:51 to be influencing double star systems in
00:03:51 --> 00:03:54 its vicinity these systems known as Nova
00:03:54 --> 00:03:57 are experiencing twice as many eruptions
00:03:57 --> 00:03:58 compared to similar Stars elsewhere in
00:03:58 --> 00:04:00 the galaxy the finding has left
00:04:00 --> 00:04:02 researchers puzzled challenging our
00:04:02 --> 00:04:04 current understanding of how black hole
00:04:04 --> 00:04:06 Jets interact with their surroundings
00:04:06 --> 00:04:08 lead author Alec lesing from Stanford
00:04:08 --> 00:04:10 University admits we don't know what's
00:04:11 --> 00:04:13 going on but it's just a very exciting
00:04:13 --> 00:04:15 finding this discovery opens up new
00:04:15 --> 00:04:17 questions about the complex
00:04:17 --> 00:04:19 relationships between black holes their
00:04:19 --> 00:04:21 Jets and the stars that inhabit their
00:04:21 --> 00:04:23 Galactic neighborhoods it's a reminder
00:04:23 --> 00:04:26 that even after Decades of observation
00:04:26 --> 00:04:27 the universe still has plenty of
00:04:27 --> 00:04:30 surprises in store for us
00:04:30 --> 00:04:32 now some exciting news from the world of
00:04:32 --> 00:04:34 exoplanet hunting astronomers have just
00:04:34 --> 00:04:36 announced the first discovery from the
00:04:36 --> 00:04:38 need Earth twin survey this new planet
00:04:38 --> 00:04:42 named HD 86728 B is orbiting a Star
00:04:42 --> 00:04:44 located about 49 light years away from
00:04:44 --> 00:04:47 us what makes this discovery special is
00:04:47 --> 00:04:49 that it showcases the incredible
00:04:49 --> 00:04:51 Precision of new instruments like this
00:04:51 --> 00:04:53 spectrograph HD
00:04:53 --> 00:04:56 86728 B has a mass about nine times that
00:04:56 --> 00:04:59 of Earth and orbits its star every 31
00:04:59 --> 00:05:00 days
00:05:00 --> 00:05:01 while this particular Planet isn't quite
00:05:01 --> 00:05:04 an earth twin its Discovery proves that
00:05:04 --> 00:05:06 we're getting better at finding smaller
00:05:06 --> 00:05:08 potentially Rocky worlds around nearby
00:05:09 --> 00:05:11 stars as we continue to refine our
00:05:11 --> 00:05:13 techniques and instruments we're inching
00:05:13 --> 00:05:15 closer to the ultimate goal of finding
00:05:15 --> 00:05:17 true earthlike planets in habitable
00:05:17 --> 00:05:19 zones around other
00:05:19 --> 00:05:21 stars this first success from the needs
00:05:21 --> 00:05:24 survey is just the beginning astronomers
00:05:24 --> 00:05:25 are optimistic that more exciting
00:05:26 --> 00:05:27 discoveries are on the horizon as they
00:05:27 --> 00:05:29 continue to search for alien worlds in
00:05:29 --> 00:05:32 our Cosmic neighborhood moving on now to
00:05:32 --> 00:05:34 a dark matter update in a surprising
00:05:34 --> 00:05:35 twist that challenges our understanding
00:05:35 --> 00:05:38 of the universe a new study suggests
00:05:38 --> 00:05:40 that dark matter may not be as aloof as
00:05:40 --> 00:05:42 we once thought scientists have long
00:05:42 --> 00:05:44 believed that dark matter interacts with
00:05:44 --> 00:05:46 regular matter only through gravity
00:05:46 --> 00:05:48 however recent observations of ultra
00:05:48 --> 00:05:49 faint dwarf galaxies are hinting at a
00:05:49 --> 00:05:52 more complex relationship the study
00:05:52 --> 00:05:54 published in the astrophysical journal
00:05:54 --> 00:05:56 letters looked at six of these tiny
00:05:56 --> 00:05:59 galaxies orbiting the Milky Way by
00:05:59 --> 00:06:01 comparing computer simulations with real
00:06:01 --> 00:06:03 world observations researchers found
00:06:03 --> 00:06:05 that the distribution of stars in these
00:06:05 --> 00:06:07 galaxies doesn't quite match what we'd
00:06:07 --> 00:06:09 expect if dark matter and regular matter
00:06:10 --> 00:06:12 were only linked by gravity this slight
00:06:12 --> 00:06:14 discrepancy could indicate that dark
00:06:14 --> 00:06:16 matter interacts with regular matter in
00:06:16 --> 00:06:18 ways we haven't yet understood while the
00:06:18 --> 00:06:20 exact nature of this interaction remains
00:06:20 --> 00:06:23 a mystery the implications are profound
00:06:23 --> 00:06:24 it could open up new avenues for
00:06:24 --> 00:06:26 detecting Dark Matter directly and force
00:06:26 --> 00:06:28 us to rethink our current models of how
00:06:28 --> 00:06:30 the universe works
00:06:30 --> 00:06:32 as always in science more data is needed
00:06:32 --> 00:06:35 to confirm these findings but if true
00:06:35 --> 00:06:36 this discovery could be a game changer
00:06:36 --> 00:06:38 in our quest to understand the enigmatic
00:06:38 --> 00:06:39 substance that makes up most of the
00:06:39 --> 00:06:41 universe's
00:06:41 --> 00:06:43 Mass that's all for today's episode of
