00:00:00 --> 00:00:01 welcome to astronomy daily with me Anna
00:00:02 --> 00:00:03 bringing you the latest space and
00:00:03 --> 00:00:05 astronomy news today we have an exciting
00:00:06 --> 00:00:08 lineup of stories from across the cosmos
00:00:08 --> 00:00:10 we'll be exploring massive magnetic
00:00:10 --> 00:00:11 tornadoes on Jupiter that are spawning
00:00:11 --> 00:00:14 earth-sized storms learn about some
00:00:14 --> 00:00:15 close calls with space debris at the
00:00:15 --> 00:00:17 International Space Station recently
00:00:17 --> 00:00:19 dive into groundbreaking asteroid
00:00:19 --> 00:00:21 research and much more let's get started
00:00:22 --> 00:00:23 with today's space
00:00:23 --> 00:00:25 headlines planetary scientists have made
00:00:25 --> 00:00:28 a remarkable discovery on Jupiter
00:00:28 --> 00:00:30 enormous magnetic tornadoes that are
00:00:30 --> 00:00:32 creating storms as large as our entire
00:00:32 --> 00:00:35 planet Earth these massive storms
00:00:35 --> 00:00:36 manifest as dark oval shapes in
00:00:37 --> 00:00:39 Jupiter's atmosphere but here's the
00:00:39 --> 00:00:41 fascinating part they're only visible
00:00:41 --> 00:00:43 when viewed in ultraviolet light the
00:00:43 --> 00:00:45 discovery came after years of
00:00:45 --> 00:00:47 observations including data from the
00:00:47 --> 00:00:49 Hubble Space Telescope and NASA's
00:00:49 --> 00:00:52 Cassini spacecraft these mysterious dark
00:00:52 --> 00:00:54 ovals are actually dense hazes of
00:00:54 --> 00:00:56 aerosols in Jupiter's Stratosphere
00:00:56 --> 00:00:58 formed by swirling magnetic vortices
00:00:59 --> 00:01:00 that twist down from the planet's
00:01:00 --> 00:01:03 ionosphere into its deep atmosphere the
00:01:03 --> 00:01:05 key to understanding these storms lies
00:01:05 --> 00:01:07 in the powerful magnetic interactions
00:01:07 --> 00:01:10 happening around Jupiter the planet is
00:01:10 --> 00:01:12 surrounded by something called the IOP
00:01:12 --> 00:01:14 plasm Taurus a donut-shaped ring of
00:01:14 --> 00:01:16 charged particles spewed out by
00:01:16 --> 00:01:19 volcanoes on Jupiter's moon IO when
00:01:19 --> 00:01:21 these particles interact with Jupiter's
00:01:21 --> 00:01:22 magnetic field they can trigger the
00:01:22 --> 00:01:25 formation of these massive tornado likee
00:01:25 --> 00:01:28 structures these magnetic tornadoes take
00:01:28 --> 00:01:30 about a month to form and and then
00:01:30 --> 00:01:32 dissipate within a couple of weeks the
00:01:32 --> 00:01:34 resulting Haze in these dark ovals is
00:01:34 --> 00:01:36 remarkably dense about 50 times thicker
00:01:36 --> 00:01:38 than typical concentration in Jupiter's
00:01:38 --> 00:01:40 atmosphere it's as if Jupiter has its
00:01:40 --> 00:01:42 own version of Tornado Alley except
00:01:42 --> 00:01:44 these storms are large enough to swallow
00:01:44 --> 00:01:45 Earth
00:01:45 --> 00:01:47 whole the International Space Station
00:01:47 --> 00:01:49 has had to take evasive action twice in
00:01:49 --> 00:01:51 less than a week to dodge dangerous
00:01:51 --> 00:01:54 space debris highlighting an increasing
00:01:54 --> 00:01:56 challenge in low earth orbit the most
00:01:57 --> 00:01:58 recent maneuver happened Monday morning
00:01:59 --> 00:02:00 when a Russian prog ress cargo
00:02:00 --> 00:02:02 spacecraft docked to the station since
00:02:02 --> 00:02:05 August fired its thrusters for about 3
00:02:05 --> 00:02:08 and 1/2 minutes to move the ISS clear of
00:02:08 --> 00:02:11 an incoming piece of space junk this
00:02:11 --> 00:02:12 came just 6 days after a similar
00:02:12 --> 00:02:15 maneuver was needed to avoid a fragment
00:02:15 --> 00:02:17 from a defunct weather satellite the
00:02:17 --> 00:02:19 growing frequency of these avoidance
00:02:19 --> 00:02:21 Maneuvers points to an increasingly
00:02:21 --> 00:02:24 crowded orbital environment there are
00:02:24 --> 00:02:25 currently over
00:02:25 --> 00:02:28 10 active satellites in orbit with
00:02:28 --> 00:02:30 spacex's starlink con station accounting
00:02:30 --> 00:02:34 for about 6 of those but the debris
00:02:34 --> 00:02:36 problem is far more extensive than just
00:02:36 --> 00:02:39 active satellites experts estimate there
00:02:39 --> 00:02:40 are around
00:02:40 --> 00:02:43 40 traed pieces of debris at least 4
00:02:43 --> 00:02:46 in wide over a million pieces between
00:02:46 --> 00:02:50 0.4 and 4 in and an astounding 130
00:02:50 --> 00:02:52 million tiny fragments at least a
00:02:52 --> 00:02:55 millimeter in size even these smallest
00:02:55 --> 00:02:58 pieces pose a serious threat as they
00:02:58 --> 00:03:01 travel at speeds around 17 mph at
00:03:01 --> 00:03:04 the station's altitude to put this
00:03:04 --> 00:03:06 growing hazard in perspective the ISS
00:03:06 --> 00:03:08 has had to perform 32 debris avoidance
00:03:08 --> 00:03:11 Maneuvers since 1999 with the frequency
00:03:11 --> 00:03:14 of these events clearly on the rise
00:03:14 --> 00:03:17 speaking of avoiding things in space in
00:03:17 --> 00:03:18 an exciting development for planetary
00:03:19 --> 00:03:21 defense scientists have unveiled a new
00:03:21 --> 00:03:23 integrated approach for studying near
00:03:23 --> 00:03:25 Earth asteroids this breakthrough was
00:03:26 --> 00:03:27 demonstrated during the observation of
00:03:27 --> 00:03:31 asteroid 2022 w J1 which was first
00:03:31 --> 00:03:33 detected by the Catalina Sky survey in
00:03:33 --> 00:03:36 Arizona last November just hours before
00:03:36 --> 00:03:37 it entered Earth's atmosphere over
00:03:37 --> 00:03:40 Southern Ontario for the first time in
00:03:40 --> 00:03:43 history astronomers were able to track
00:03:43 --> 00:03:46 and study an incoming asteroid in detail
00:03:46 --> 00:03:47 during the brief window between its
00:03:47 --> 00:03:50 Discovery and Atmospheric entry using
00:03:50 --> 00:03:52 the Lowel Discovery telescope's rapid
00:03:52 --> 00:03:55 tracking capabilities researchers
00:03:55 --> 00:03:57 observed the asteroid for about an hour
00:03:57 --> 00:03:58 before it disappeared into Earth's
00:03:58 --> 00:04:01 shadow moving at an incredible 5° per
00:04:01 --> 00:04:04 second across the sky the combined data
00:04:04 --> 00:04:06 from telescopic observations and
00:04:06 --> 00:04:08 Fireball cameras allowed scientists to
00:04:08 --> 00:04:12 determine that 2022 wj1 was a silica
00:04:12 --> 00:04:15 Rich object just 40 to 60 cm wide making
00:04:16 --> 00:04:17 it the smallest asteroid ever
00:04:17 --> 00:04:20 characterized before impact this precise
00:04:20 --> 00:04:22 size calculation was possible thanks to
00:04:22 --> 00:04:23 measurements of the asteroids
00:04:23 --> 00:04:26 reflectivity as it approached Earth this
00:04:26 --> 00:04:28 new methodology of combining space-based
00:04:28 --> 00:04:30 detection with with ground-based
00:04:30 --> 00:04:32 observation provides unprecedented
00:04:32 --> 00:04:34 detail about incoming asteroids and
00:04:34 --> 00:04:36 represents a significant advancement in
00:04:36 --> 00:04:39 our ability to study these objects the
00:04:39 --> 00:04:40 success of this approach suggests we'll
00:04:40 --> 00:04:42 be able to gather even more detailed
00:04:42 --> 00:04:45 information about future Earth impacting
00:04:45 --> 00:04:47 asteroids enhancing our understanding of
00:04:47 --> 00:04:49 these Celestial visitors and improving
00:04:49 --> 00:04:51 our planetary defense
00:04:51 --> 00:04:54 capabilities and a little update Earth
00:04:54 --> 00:04:56 has Bid Farewell to its temporary
00:04:56 --> 00:04:59 companion as asteroid 2024 pt5 has
00:04:59 --> 00:05:01 officially ended its brief stint as our
00:05:01 --> 00:05:05 planet's second moon the 37t wide Space
00:05:05 --> 00:05:07 Rock which had been orbiting Earth since
00:05:07 --> 00:05:09 September 29th departed on Monday at
00:05:09 --> 00:05:13 10:43 a.m. eastern time scientists who
00:05:13 --> 00:05:15 track this Celestial visitor say it's
00:05:15 --> 00:05:17 been a fascinating opportunity to study
00:05:17 --> 00:05:19 these temporary orbital captures Dr
00:05:19 --> 00:05:21 Carlos delafuente Marcos of the
00:05:21 --> 00:05:24 Universidad computa Madrid who helped
00:05:24 --> 00:05:26 discover the asteroids Mini Moon status
00:05:26 --> 00:05:29 explains that 2024 pt5 is typically part
00:05:29 --> 00:05:32 of the Arjuna asteroid belt a collection
00:05:32 --> 00:05:34 of objects that Circle the sun in orbits
00:05:34 --> 00:05:37 very similar to Earth's looking ahead
00:05:37 --> 00:05:38 astronomers have calculated several
00:05:38 --> 00:05:42 future close approaches of 2024 pt5 to
00:05:42 --> 00:05:44 our planet the next visit is expected on
00:05:44 --> 00:05:47 January 9th 2025 when it will pass
00:05:47 --> 00:05:51 within about 1.1 million miles of Earth
00:05:51 --> 00:05:52 however its velocity during this
00:05:52 --> 00:05:54 approach may be too high for Earth's
00:05:54 --> 00:05:56 gravity to capture it again a more
00:05:56 --> 00:05:58 promising opportunity might come in May
00:05:58 --> 00:06:01 2084 when conditions could be just right
00:06:01 --> 00:06:04 for another temporary capture while we
00:06:04 --> 00:06:06 say goodbye to this particular Mini Moon
00:06:06 --> 00:06:08 scientists remind us that such temporary
00:06:09 --> 00:06:11 captures are relatively common with
00:06:11 --> 00:06:13 several typically occurring Each decade
00:06:13 --> 00:06:15 these events provide valuable
00:06:15 --> 00:06:17 opportunities to study neear objects and
00:06:17 --> 00:06:18 better understand the complex
00:06:19 --> 00:06:20 gravitational dance between Earth and
00:06:20 --> 00:06:22 its Cosmic
00:06:22 --> 00:06:24 neighbors the James web Space Telescope
00:06:24 --> 00:06:26 is helping astronomers tackle one of the
00:06:26 --> 00:06:29 biggest questions in exoplanet research
00:06:29 --> 00:06:32 which Distant Worlds have atmospheres a
00:06:32 --> 00:06:35 new study focusing on the superar glea
00:06:35 --> 00:06:38 486b is providing crucial insights into
00:06:38 --> 00:06:40 what scientists call The Cosmic
00:06:40 --> 00:06:42 Shoreline the dividing line between
00:06:42 --> 00:06:44 planets that can maintain atmospheres
00:06:44 --> 00:06:45 and those that
00:06:45 --> 00:06:49 cannot located just 26 Lighty years away
00:06:49 --> 00:06:53 gisa 486b is about 2.8 times the mass of
00:06:53 --> 00:06:55 Earth and orbits a small active Red
00:06:55 --> 00:06:58 Dwarf star recent web observations
00:06:58 --> 00:07:00 reveal the plan planet has a scorching
00:07:00 --> 00:07:03 day side temperature of 865 kelv
00:07:03 --> 00:07:05 measured with unprecedented Precision to
00:07:06 --> 00:07:07 within just
00:07:07 --> 00:07:09 14° this extreme heat suggests the
00:07:09 --> 00:07:12 planet has either a very thin atmosphere
00:07:12 --> 00:07:14 or none at all as a thick atmosphere
00:07:14 --> 00:07:16 would help distribute heat more evenly
00:07:17 --> 00:07:18 the findings are particularly
00:07:18 --> 00:07:20 significant because they help scientists
00:07:20 --> 00:07:21 understand how planets orbiting red
00:07:21 --> 00:07:24 dwarf stars the most common type of star
00:07:24 --> 00:07:26 in our galaxy might lose their
00:07:26 --> 00:07:27 atmospheres over billions of years due
00:07:27 --> 00:07:30 to intense Stellar activity
00:07:30 --> 00:07:32 this knowledge is crucial as astronomers
00:07:32 --> 00:07:33 continue their search for potentially
00:07:33 --> 00:07:36 habitable worlds suggesting they should
00:07:36 --> 00:07:39 focus on more massive planets or those
00:07:39 --> 00:07:41 receiving less intense Stellar radiation
00:07:41 --> 00:07:43 if they want to find worlds that have
00:07:43 --> 00:07:45 held on to their
00:07:45 --> 00:07:48 atmospheres finally today time to say
00:07:48 --> 00:07:50 congratulations scientists in India are
00:07:50 --> 00:07:52 celebrating the first major breakthrough
00:07:52 --> 00:07:54 from their adicha L1 solar observation
00:07:54 --> 00:07:56 Mission the country's pioneering Venture
00:07:56 --> 00:07:59 into solar studies using their advanced
00:07:59 --> 00:08:00 ible emission line coronograph
00:08:01 --> 00:08:03 instrument researchers have successfully
00:08:03 --> 00:08:05 captured and analyzed detailed data
00:08:05 --> 00:08:08 about massive solar eruptions known as
00:08:08 --> 00:08:09 coronal mass
00:08:09 --> 00:08:11 ejections these powerful solar events
00:08:11 --> 00:08:14 can weigh up to a trillion kilogram and
00:08:14 --> 00:08:16 hurdle through space at speeds reaching
00:08:16 --> 00:08:18 3
00:08:18 --> 00:08:21 km/s when directed toward Earth they can
00:08:21 --> 00:08:24 Traverse the 150 million kilm journey in
00:08:24 --> 00:08:27 as little as 15 hours potentially
00:08:27 --> 00:08:28 causing significant disruptions to our
00:08:28 --> 00:08:31 technology dependent world the mission's
00:08:31 --> 00:08:33 ability to precisely track these solar
00:08:33 --> 00:08:35 storms could prove invaluable for
00:08:35 --> 00:08:37 protecting our modern
00:08:37 --> 00:08:38 infrastructure these events can
00:08:38 --> 00:08:41 interfere with satellite operations
00:08:41 --> 00:08:43 disrupt power grids and affect global
00:08:43 --> 00:08:46 communication systems by providing early
00:08:46 --> 00:08:49 warnings of incoming solar storms adicha
00:08:49 --> 00:08:51 l1's observations could give us crucial
00:08:52 --> 00:08:53 time to safeguard sensitive equipment
00:08:53 --> 00:08:55 and maintain essential
00:08:55 --> 00:08:57 Services what makes this achievement
00:08:57 --> 00:08:59 particularly noteworthy is the
00:08:59 --> 00:09:02 spacecraft's unique vantage point and
00:09:02 --> 00:09:05 capabilities its specialized coronagraph
00:09:05 --> 00:09:07 can observe the sun's outer Corona
00:09:07 --> 00:09:09 continuously providing uninterrupted
00:09:09 --> 00:09:11 monitoring that could help us better
00:09:11 --> 00:09:13 understand and predict these potentially
00:09:13 --> 00:09:15 hazardous solar phenomena this
00:09:15 --> 00:09:17 advancement positions India among the
00:09:17 --> 00:09:19 select group of Nations capable of
00:09:19 --> 00:09:21 conducting sophisticated solar research
