0:09 in the center of our solar system
0:13 lies a serial killer
0:17 here where the powerful explosions occur
0:21 violent forces have erupted time and
0:24 time again leaving only destruction and
0:28 disruption in their wake
0:31 a century and a half ago it erupted with
0:34 such intensity that it may have been the
0:38 biggest explosion in the solar system in
0:41 all of human history
0:43 and today the countdown to the next big
0:47 disaster has begun once again
0:51 it's a story of a star that's both our
0:54 creator and Destroyer
0:57 it is the story of our son
1:04 [Music]
1:14 it's August 4th 1972.
1:20 crew members aboard the U.S task force
1:24 77 aircraft are flying over the
1:27 Strategic ports off the coast of North
1:30 Vietnam
1:31 [Music]
1:32 it's the midst of the Vietnam War
1:37 during their flyby of the haifeng harbor
1:40 they are jolted with a series of
1:43 deafening explosions
1:47 despite the clear weather and the
1:50 absence of any visible warships in sight
1:53 that could have caused such a
1:55 disturbance
1:57 in total around 20 to 30 explosions were
2:02 documented in a mere 30 second span
2:06 all of these explosions had happened
2:09 underwater
2:11 the mines had been strategically planted
2:14 there three months earlier by the United
2:17 States Navy themselves as part of
2:20 operation pocket money
2:23 a U.S plan to block North Vietnam from
2:27 Maritime trade during the Vietnam war
2:31 and these Minds were supposed to
2:34 detonate when a ship passes above them
2:37 the mine would sense a change to the
2:40 magnetic field density and trigger an
2:42 explosion
2:44 but instead all of them blasted on their
2:47 own
2:48 [Music]
2:50 for over four decades the cause of this
2:53 event remained shrouded in mystery until
2:57 a recent study of the newly Declassified
2:59 U.S Navy documents revealed that the
3:03 culprit was not of any Earthly origin
3:06 but rather
3:08 someone from above
3:11 Sun
3:15 [Music]
3:17 the sun it is an object in our solar
3:20 system that really needs no introduction
3:24 for centuries its power has spoken for
3:27 itself
3:31 to the ancient Egyptians the Sun God Ra
3:34 was one of the most important and
3:37 Powerful deities
3:39 he was often depicted with the head of a
3:42 falcon and the sun disc on his head
3:45 symbolizing his connection to the Sun
3:50 as the solar God Ra's Radiance would
3:53 warm the land bring life to crops
3:57 and cast its Golden Glow across the
4:00 Nile's Tranquil Waters
4:02 raw was believed to be the creator of
4:05 the world
4:06 responsible for bringing light and life
4:09 to the cosmos
4:11 a radiant deity who skillfully upheld
4:15 the universe's Harmony
4:17 with his Brilliance reaching every
4:19 corner of existence
4:22 therefore with such a deep influence on
4:26 their culture the ancient Egyptians
4:28 revered the Sun God Ra not only for his
4:32 life-giving power
4:34 but also for his role as the ultimate
4:37 judge observing the actions of humanity
4:40 from his Divine vantage point
4:43 and so there are many instances where
4:46 raw was also associated with his
4:49 destructive forms
4:50 one of the most well-known destructive
4:53 aspects of raw was his eye often
4:56 referred to as the eye of raw
4:59 this eye could transform into a lioness
5:03 or a fiery aggressive form representing
5:07 the destructive power of the sun's heat
5:09 and light
5:11 it was believed that raw could send his
5:14 eye as a raging weapon to punish or
5:18 destroy those who opposed him or
5:21 threatened Cosmic order
5:23 Egyptian mythology is filled with
5:26 stories much like this one wherein Ra's
5:29 anger or displeasure could lead to
5:32 destructive events such as droughts
5:35 plagues or other natural disasters
5:39 raw's anger and Furious aspect were
5:43 symbolic of the potentially destructive
5:46 power of the sun's Rays when unchecked
5:50 even today centuries later
5:54 the cultural resonance between the fury
5:56 of the Eye of Ra and the unrestrained
5:59 power of the sun endures across various
6:03 mindsets
6:06 2 in the perspectives of modern day
6:09 astrophysicists
6:11 according to NASA in an increasingly
6:14 technological world where almost
6:17 everyone relies on cell phones and GPS
6:20 controls not just your in-car map system
6:24 but also airplane navigation and the
6:27 extremely accurate clocks that govern
6:30 Financial transactions space weather is
6:33 a serious matter
6:37 recently you might have encountered an
6:41 array of news articles delving into the
6:44 escalating violence and instability
6:46 displayed by our sun
6:49 it's nearly becoming routine for the sun
6:52 to unleash at least one solar storm per
6:55 week
6:57 just a few weeks ago in June the sun
7:00 gave rise to over 160 sunspots account
7:05 not surpassed in more than two decades
7:09 it's the beginning of what scientists
7:11 call the peak of the solar cycle 25.
7:15 and while many space agencies predicted
7:18 a maximum monthly count of 125 sunspots
7:23 during the 25th solar Cycles Peak
7:26 the star is now on a trajectory to Peak
7:30 at just under 200 monthly sunspots
7:35 but what's driving this change in the
7:38 sun's Behavior how did the sun trigger
7:41 the mine explosions
7:43 there are plenty of questions
7:46 and as always space phenomena rarely
7:49 have any straightforward answer
7:52 but let's start from the beginning
7:53 [Music]
7:56 about 4.6 billion years ago a massive
8:01 cloud of gas and dust in space also
8:04 known as a molecular cloud began
8:07 collapsing under its own gravity
8:10 what triggered this collapse is still a
8:13 matter of debate among scientists
8:16 but according to the latest research and
8:19 the prevailing consensus the collapse is
8:22 believed to have been set in motion by a
8:25 nearby event that sent powerful shock
8:28 waves such as a supernova explosion or
8:31 the gravitational forces exerted by
8:34 Young stars as they compressed the
8:37 surrounding gas
8:39 because of the shock wave the molecular
8:41 cloud began to contract starting to spin
8:45 faster and faster and finally flattened
8:48 into a rotating disc due to the
8:51 conservation of angular momentum
8:55 this flattened disc would eventually
8:57 give rise to our future solar system
9:02 in the center of this spinning disc a
9:05 dense region began to form due to
9:07 gravitational attraction
9:11 drawing in gas and dust from the
9:13 surrounding area this dense core
9:16 accumulated more and more material
9:20 and as the core grew in both size and
9:23 Mass
9:24 its gravitational pull intensified thus
9:27 attracting even more material
9:31 eventually the increasing pressure
9:33 caused temperatures in the core to
9:35 Skyrocket reaching millions of degrees
9:38 Celsius or Fahrenheit
9:41 at these super high temperatures a
9:43 process known as nuclear fusion began to
9:46 initiate
9:48 hydrogen atoms in the core collided with
9:50 each other with such force that they
9:53 merged and formed helium atoms releasing
9:56 an Untold amount of energy in the
9:58 process
10:00 pushing against the pull of gravity that
10:03 was attempting to crush the star's
10:05 material the energy from these nuclear
10:08 fusion reactions strive to move outward
10:11 creating a pressure that sought to
10:13 expand the star
10:15 this delicate equilibrium between
10:18 outward pushing energy and the inward
10:20 pulling gravity established a stable
10:23 state that has persisted for billions of
10:26 years
10:28 the Inception of this balance marked the
10:31 birth of a new star in the universe
10:34 our sun
10:36 this outward moving energy travels from
10:39 the sun's layers to its surface where
10:42 it's emitted as sunlight
10:44 this energy manifests as both light and
10:48 heat extending to every planet and
10:51 object within our solar system
10:55 fast forward to the present day and the
10:58 sun finds itself halfway through its
11:00 life cycle shining about 30 percent more
11:03 brightly than it did in its earlier
11:06 stages
11:08 it currently experiences the most stable
11:11 phase of its life cycle known as the
11:14 main sequence a state it is maintained
11:17 since its Inception roughly 4.6 billion
11:20 years ago
11:21 therefore unlike most other violent
11:25 Stars our sun has provided for a
11:28 relatively stable environment in which
11:30 life can flourish
11:32 its energy permeates nearly every facet
11:35 of Life on our planet the Vitality of
11:38 our ecosystems the warmth that Embraces
11:41 us and the sustenance of countless
11:44 organisms all hinge on this Cosmic
11:47 Wellspring
11:49 the Sun's light forms the Bedrock of our
11:52 existence nurturing growth guiding
11:55 weather patterns and invigorating
11:57 Earth's complex Web of Life
12:00 just look at how precisely it provides
12:03 just the right amount of warmth and
12:05 Light enabling plants to undergo
12:08 photosynthesis wherein they harness the
12:11 sun's energy and convert it into
12:13 essential carbohydrates
12:16 gradually this solar energy travels up
12:19 the food chain ultimately nourishing us
12:22 humans
12:24 as we consume and metabolize this food
12:27 we gain The crucial energy that keeps
12:30 our bodies functioning properly
12:33 this transfer of energy traces a
12:36 remarkable path back to the Sun
12:39 the source of all life and the first
12:42 link in the food chain
12:44 the sun is our creator
12:48 yet beneath its gentle cradle
12:51 Shadows of uncertainty have found refuge
12:54 for billions of years
12:57 visualizing the sun via the eyes of
13:00 space observatories reveals an entirely
13:03 different story
13:05 much like every other star even our own
13:09 star boasts a landscape of dynamic
13:12 activity
13:13 in fact the most powerful explosions in
13:16 the solar system occur here
13:18 each passing second Witnesses the
13:22 generation of more energy through these
13:24 eruptions than Humanity has consumed
13:27 throughout its entire history and to be
13:30 fair It's Perfectly Normal for our Sun
13:33 to produce this much energy
13:35 however problems start arising when such
13:38 huge amounts of energies get trapped and
13:41 locked within the Sun
13:43 similar to how Earth's magnetic field is
13:46 created by the movement of its core The
13:49 Sun Also possesses its unique magnetic
13:52 field generated by the motion of charged
13:55 particles in its superheated core
13:58 emerging from the solar surface this
14:01 magnetic field extends beyond the
14:04 confines of the sun's outermost
14:05 atmospheric layer
14:07 reaching out into the vast expanse of
14:10 the solar system
14:12 accompanying it is the unending stream
14:15 of solar particles known as the solar
14:18 wind
14:19 the solar wind consists of a continuous
14:22 flow of charged particles primarily
14:25 electrons and protons that Journey
14:27 outward from the Sun into outer space
14:31 this wind emerges from the sun's
14:34 incredibly high temperatures and the
14:37 intense energy present within its
14:39 outermost layer known as the corona
14:43 the Corona's extreme heat provides
14:45 enough kinetic energy to propel
14:48 particles to achieve tremendous speeds
14:51 allowing them to break free from the
14:53 sun's gravitational grasp this process
14:56 gives birth to an uninterrupted Cascade
15:00 of such particles
15:02 this solar wind however is far from
15:05 uniform it comprises a complex mixture
15:08 of particles characterized by varying
15:11 speeds densities and energies that form
15:15 an unceasing yet ever-changing stream
15:18 that permeates the entirety of the solar
15:21 system their journey is facilitated by
15:25 the sun's magnetic field which guides
15:27 the path of these particles and gives
15:30 rise to a form of space weather
15:34 during a typical day the solar wind
15:37 flows continuously past the Earth 24 7.
15:41 distorting its magnetic field and
15:44 pulling it around the back in a
15:46 tail-like structure
15:48 our Earth's magnetic field easily
15:50 manages to withstand most of these winds
15:54 some of them engage with Earth's
15:57 magnetosphere and atmosphere
15:59 different gas particles in the
16:01 atmosphere produce different colors in
16:03 auroras nitrogen atom auroras look red
16:07 oxygen green and hydrogen blue
16:11 auroras become visible in various
16:14 locations depending on the intensity of
16:16 the solar wind striking Earth
16:19 and as a result these otherwise
16:22 dangerous particles from the Sun are
16:24 rendered harmless and become a rather
16:27 beautiful phenomenon
16:29 these breathtaking displays of light are
16:32 a common occurrence on nearly all
16:34 planets within our solar system and they
16:37 typically do not cause harm or
16:39 disruption to planetary routines
16:42 however as the rotational speed between
16:45 the sun's poles and equator increases it
16:49 initiates a twisting Motion in the
16:51 magnetic field giving rise to a complex
16:55 and entangled structure and amplifying
16:58 its power even further
17:01 this results in the formation of
17:03 magnetic knots that accumulate enormous
17:06 amounts of energy akin to a coiled
17:09 rubber band
17:10 when these knots eventually twist and
17:13 snap the pent-up energy is released into
17:16 space
17:17 if Earth finds itself in the wrong place
17:20 at the wrong time during such an energy
17:23 discharge events like geomagnetic storms
17:27 can unfold
17:28 [Music]
17:29 the last time a strong solar wind
17:32 hurricane washed over Earth was in 1859
17:36 the Carrington event the largest
17:39 geomagnetic storm ever observed on Earth
17:44 September 1st 1859
17:48 a powerful storm started Gathering force
17:52 on the surface of the Sun
17:54 it's the beginning of the most violent
17:57 explosion in our solar system
18:00 in a matter of minutes a blazing Ark
18:04 began its Ascent from the surface of the
18:06 Sun
18:07 surpassing the size of Earth multiple
18:10 times over
18:13 at some time during noon on that very
18:15 day
18:16 the ark finally reached its breaking
18:19 point and a huge mass of solar material
18:22 was ejected into space
18:25 only one slight problem
18:28 it was pointed squarely at Earth
18:32 the event however hadn't gone unnoticed
18:35 an English astronomer by the name of
18:38 Richard Carrington was independently
18:41 observing the sun using his telescope
18:44 when he suddenly noticed something odd
18:48 through his lens he spots two bright
18:51 flashes of light bursting onto the
18:54 surface of the Sun
18:55 however lacking a comprehensive
18:58 understanding of this newfound
19:00 phenomenon he failed to grasp the
19:03 significance of what had just transpired
19:07 he moves on and resumes his study of the
19:10 Sun as usual believing that there was no
19:13 sign that anything should be amiss
19:16 but although he didn't realize it then
19:18 Richard Carrington had just witnessed
19:21 the beginning of something that would
19:23 eventually become the most intense solar
19:26 storm in all of human history
19:30 racing at a velocity of around 2 000
19:34 kilometers per second the solar Outburst
19:37 hurdled closer to Earth with every
19:39 passing minute on track to make impact
19:42 within the next 18 hours
19:46 as Darkness enveloped half the globe the
19:50 majority of the population remained
19:52 blissfully oblivious to the imminent
19:55 disaster that would unfold in the hours
19:57 to come
20:00 it is September the 2nd 1859 the Earth
20:04 is finally struck by a powerful solar
20:07 storm
20:09 observers from around the globe are
20:12 treated to its arrival
20:15 particles from the solar Outburst
20:18 energize the atoms present in the upper
20:21 layers of Earth's atmosphere
20:23 giving rise to a mysterious glow in the
20:26 night sky at various locations
20:30 reports indicate that that night these
20:34 lights now known as auroras or Northern
20:37 or Southern Lights were visible even
20:40 down to Regions such as Europe North
20:43 America and even as far as Mexico and
20:47 Cuba
20:48 people woke up at night confused and
20:51 still tired they were sure it was
20:54 already mourning since it was so bright
20:56 outside
20:58 but when they peered out of their
20:59 Windows they discovered it wasn't the
21:02 sunlight
21:03 the skies were lit by countless intense
21:06 auroras red green and purple
21:10 people gathered and gazed upwards
21:12 terrified and awestruck in equal measure
21:16 many people around the world had never
21:19 seen an aurora before so they were
21:22 unsure of how to interpret the sky's
21:25 unusual brightness
21:27 for almost a week those living in the
21:30 northeastern part of the United States
21:32 could read a newspaper just using the
21:35 Aurora's light
21:37 the vast majority had no idea what they
21:40 were witnessing and only surmised it to
21:43 be the end of the world
21:46 however as mesmerizing as the auroras
21:49 were an unsettling occurrence had
21:52 unfolded
21:53 the telegraph which was the sole
21:56 communication system at the time had
21:59 caught fire along the lines at several
22:01 places
22:03 the intense surge of solar energy
22:05 overloaded the telegraph lines causing
22:08 widespread fires and electrical
22:11 malfunctions at multiple points along
22:13 the network
22:15 with the telegraph system paralyzed
22:18 communication breakdowns caused
22:21 confusion delays and economic losses
22:24 emergency responses were hindered and
22:28 families separated by distance couldn't
22:31 connect during the crisis adding to
22:33 their worries
22:35 the aftermath was Dire the collapse of
22:38 the telegraph system induced disruptions
22:41 that persisted for several days
22:44 but shockingly in certain regions there
22:47 were reports that people could still use
22:50 their devices and send and receive
22:53 messages as if an electric charge
22:55 coursed through the air
22:58 in the majority of cases however there
23:01 were operators who encountered electric
23:03 shocks while handling their devices with
23:06 Telegraph pylons crackling with Sparks
23:10 repairing the lines consumed months of
23:13 dedicated effort
23:15 people simply couldn't wrap their heads
23:17 around what was happening and back then
23:20 very few people knew that the sun was to
23:23 blame for the chaos
23:26 the event marked our first silent
23:28 warning
23:30 a clear indication that our otherwise
23:33 peaceful Star located 90 million miles
23:37 away from us and visible to us every day
23:41 possessed the power to disrupt our way
23:44 of life and communication
23:47 fortunately in those days our Reliance
23:51 on electricity and electronics was
23:54 minimal
23:55 so we were lucky enough to escape with
23:58 such a small warning
24:01 by looking back in time you'll quickly
24:04 realize that it's nothing short of a
24:07 miracle just how narrowly and closely we
24:11 have escaped numerous technological and
24:14 economic doomsday scenarios that could
24:17 have Arisen from the Sun
24:20 May 15 1921
24:24 the 1921 railroad storm of New York also
24:29 known as the great railroad storm stands
24:33 as another witness of the horrors that
24:36 space weather can wreak
24:38 in the early 1920s railroads were the
24:42 vital arteries and lifelines of
24:44 transportation and commerce connecting
24:47 cities and industries across vast
24:50 distances
24:52 Telegraph communication was an essential
24:55 tool for coordinating train schedules
24:57 managing operations and ensuring the
25:01 safety of passengers and cargo
25:04 May 15 1921 changed everything
25:09 a colossal solar storm erupted from the
25:13 sun's surface unleashing a powerful
25:16 burst of solar plasma towards Earth
25:19 the burst was so massive and energetic
25:22 that it disrupted the Earth's magnetic
25:25 field in minutes upon impact
25:28 as the solar Storm's charged particles
25:31 interacted with the Earth's magnetic
25:34 field powerful induced currents surged
25:38 through the extensive Telegraph Network
25:40 that ran parallel to the Rail lines
25:44 Telegraph operators stationed in
25:47 railroad hubs suddenly found their
25:49 communication lines plagued by intense
25:52 interference
25:54 messages became garbled and crucial
25:57 instructions were lost amidst the
26:00 chaotic signals
26:01 the disruption of telegraph
26:03 communication had severe consequences
26:06 for the smooth functioning of the
26:08 railroad system train schedules became
26:11 erratic and unreliable causing delays
26:15 and confusion for passengers and Freight
26:18 dispatchers struggled to relay critical
26:21 information and the coordination of
26:24 train movements became a formidable
26:26 challenge
26:28 March 13 1989
26:32 130 years later on March 13
26:36 1989 the sun Unleashed its power once
26:40 again with repercussions even more
26:42 profound
26:44 this time the entire Canadian province
26:47 of Quebec was blacked out once again the
26:51 massive influx of electrical currents
26:54 and charged particles from the Sun
26:56 overwhelmed the transmission lines and
26:59 caused a cascading failure across the
27:02 province's power grid
27:04 within seconds the entire electrical
27:07 network was compromised and Quebec was
27:10 left in complete darkness
27:12 more than 6 million people were left
27:15 without electricity for several hours
27:18 with frigid winter conditions adding to
27:21 the challenge
27:23 the outage brought life to a standstill
27:26 disrupting Transportation Systems
27:28 shutting down businesses and leaving
27:31 residents stranded in buildings and
27:34 elevators the lack of electricity also
27:38 resulted in the shutdown of water
27:40 treatment plants leaving citizens
27:42 without access to clean water
27:45 the impact of the blackout even extended
27:48 Beyond Quebec's borders affecting parts
27:51 of the Northeastern United States as
27:53 well but while the American grid was
27:56 more resilient the interconnected nature
27:59 of the Power Systems meant that the
28:01 disturbances could have easily spread
28:04 across the region highlighting the
28:06 vulnerability of interconnected
28:08 electrical Networks
28:10 as darkness and silence blanketed the
28:14 cities during that night they resembled
28:16 nothing more than Eerie ghost towns
28:19 some regions had their power restored
28:22 within a few hours While others took
28:25 several days to recover
28:28 July 23 2012.
28:32 a modern day wake-up call resounded in
28:35 2012 when the end of the Mayan calendar
28:38 stirred widespread fears of an asteroid
28:41 Collision that could extinguish all Life
28:44 as We Know It
28:46 although nothing like that happened fate
28:49 however took a different course and
28:52 something truly unexpected did take
28:55 place that year on July 23 2012 the
29:00 scariest chain of events overtook our
29:02 entire solar system
29:05 two enormous bursts of charged outbursts
29:08 were released by the sun
29:10 expansive electrified gas clouds rapidly
29:14 expanded and raced outward
29:17 fortunately our planet was present on
29:20 the other side at the time of this
29:22 eruption however had this event occurred
29:25 just nine days earlier our planet would
29:29 have been squarely in the path of that
29:31 storm
29:33 it could have taken as much as a decade
29:35 to fully regain normalcy and an
29:39 onslaught of major disruptions to
29:41 electronics Communications and power
29:43 grids on the ground to Aviation
29:45 equipment and satellites in the sky
29:48 would have been inevitable
29:51 even the depths of the ocean would not
29:54 have been spared
29:55 with underwater online communication
29:58 cables facing destruction the world
30:01 would have plunged into a month's long
30:03 internet apocalypse
30:06 with estimated damages reaching billions
30:09 if not trillions of dollars
30:12 total Havoc would ensue on the ground in
30:15 the sky and beneath the waves
30:19 and the truth is some countries might
30:22 still be grappling with the aftermath of
30:25 that powerful solar wind even to this
30:28 day
30:29 given our ever-expanding Reliance on
30:32 technology the rapid pace of scientific
30:36 advancements and our Ambitions in space
30:39 exploration it's becoming increasingly
30:42 apparent that underestimating the sun's
30:45 impact on Earth is a blunder Humanity
30:48 can no longer afford
30:53 realization of the sun's capacity to
30:57 influence our way of life has brought us
30:59 face to face with a new kind of
31:02 burgeoning field heliophysics
31:06 data from the sun's exterior scientists
31:10 globally have started monitoring and
31:12 modeling these fields as they erupt all
31:15 around the sun's surface twisting and
31:18 looping
31:19 plasma Rising toward the surface follows
31:23 these magnetic field lines which can
31:26 sometimes stifle the rising columns
31:28 forming relatively cool patches
31:32 that's where sunspots form
31:36 each Sunspot can be anywhere from 15
31:39 kilometers in size to around 160
31:43 000 kilometers that's 10 times the size
31:46 of Earth
31:48 four centuries ago with the Advent of
31:51 telescopes in the 17th century
31:54 astronomers worldwide gained the ability
31:57 to closely observe the sun's surface
32:01 not knowing that looking at our very own
32:04 star would damage his eyesight Galileo
32:07 Galilei pointed his telescope towards
32:10 the Sun
32:13 governed that the sun has dark moving
32:16 spots he called them sunspots
32:20 Galileo's telescopic observations of
32:23 sunspots marked a turning point in the
32:26 systematic study of the Sun
32:28 he was the first to argue that these
32:31 blotches were actually on the sun's
32:34 surface though he suspected they were
32:36 clowns
32:38 he made several other groundbreaking
32:40 observations leading to the realization
32:43 that the sun was not a perfect
32:46 unblemished spear but a dynamic entity
32:49 with its own set of mysteries
32:53 the nature of these sunspots remained
32:56 unclear until 1908 when astronomer
32:59 George Ellery Hale demonstrated the link
33:02 between them and magnetic fields
33:06 over time scientists have carefully
33:09 studied the peculiar shapes of sunspots
33:12 in their quest for understanding
33:15 what they didn't see until recently was
33:18 the pressure building around them
33:20 using data from the solar and
33:23 heliospheric Observatory Soho scientists
33:27 are learning to read undulations on the
33:30 surface of the Sun the results of
33:32 pressure waves ricocheting through its
33:34 volume
33:35 like the study of earthquakes on Earth
33:38 this field called Helio seismology is a
33:42 window into the movements of gases
33:44 inside the sun
33:46 it can also generate predictions of
33:49 sunspots including those forming on the
33:52 far side
33:53 detectors aboard the Soho spacecraft
33:56 have managed to catch the movement when
33:59 the energy capped by a sunspot is
34:01 suddenly released a shock wave travels
34:05 rapidly outward like a solar tsunami
34:08 with enough Force to circle the star
34:11 that signals the start of a coronal mass
34:15 ejection or a CME a coronal mass
34:18 ejection is a powerful event on the sun
34:21 where it releases a huge burst of
34:24 charged particles magnetic fields and
34:26 plasma into space
34:29 with a Corona graph to block out the
34:31 bright light of the sun we can see how
34:34 violent our sun can get
34:37 if a CME is detected blasting out from
34:40 behind this artificial Eclipse you know
34:43 that our satellites and Power Systems on
34:46 Earth are going to get hit hard
34:48 especially if it's been launched in the
34:51 direction of where Earth will be in its
34:53 orbit in about 24 to 36 hours
34:59 when solar winds of a coronal mass
35:01 ejection event hit Earth it's an
35:05 entirely different story they'll
35:07 severely compress Earth's magnetic field
35:10 as they pass creating an intense
35:13 geomagnetic storm and when a magnetic
35:16 field line breaks the charged particles
35:19 trapped in it travel back to Earth
35:22 inducing electrical currents into the
35:25 Earth's surface and anything running
35:27 over it such as power lines
35:30 it'll also pack the boundary of Earth
35:33 with solar plasma
35:35 as this plasma interacts with Earth's
35:39 magnetic field turbulence emerges along
35:42 its Leading Edge cracks begin to form
35:45 puncturing and creating openings in
35:47 Earth's protective shield enabling the
35:50 entry of vast amounts of radioactive
35:53 particles into the atmosphere
35:56 these particles originate from another
35:59 phenomena known as solar flares
36:02 these coronal mass ejections are not
36:06 isolated events instead they often
36:09 coincide with something known as solar
36:12 flares
36:14 a solar flare can be conceptualized as a
36:17 volatile eruption transpiring on the
36:20 sun's surface varying in duration from
36:23 minutes to hours
36:26 players materialize as surges of charged
36:30 radioactive particles and x-rays
36:32 hurtling towards space at the speed of
36:35 light large solar flares can release
36:39 enough energy to power the entire United
36:42 States for a million years
36:46 and to better understand their nature
36:49 scientists have classified flares
36:51 according to their strength
36:53 the smallest ones are b-class followed
36:57 by c m and X as the largest
37:01 similar to the Richter scale for
37:03 earthquakes each letter represents a
37:06 tenfold increase in energy output
37:09 an X is 10 times an m and 100 times a c
37:15 within each letter class there's an even
37:18 finer scale from one to nine
37:21 C-Class flares are too weak to
37:24 noticeably affect Earth
37:27 in class flares can induce momentary
37:30 radio blackouts at the poles and minor
37:33 radiation storms that might jeopardize
37:35 astronauts
37:37 it's the x-class flares that are the
37:40 real powerhouses
37:42 although X is the highest letter on the
37:45 scale
37:47 some flares go even Beyond nine in their
37:50 strength
37:51 the Carrington event was an x-45 class
37:55 flare
37:56 Quebec blackout was an X 1.4 class
38:01 and the solar storm of 2012 was an x-28
38:05 class flare
38:06 the Carrington storm of 1859 is the
38:10 largest recorded solar storm ever
38:13 recorded the existence of solar flares
38:16 stronger than this is anyone's best
38:19 guess
38:21 a powerful x-class flare like that today
38:25 could create long-lasting radiation
38:28 storms which can harm satellites and
38:31 even get airline passengers flying near
38:34 the Pole's radiation doses
38:37 is what happened in 2016 to Marie Moe a
38:41 cyber security researcher Mo felt her
38:44 pacemaker glitch while on a plane to
38:47 Amsterdam a muscle in her chest started
38:50 to Twitch
38:51 she looked down and the muscle was
38:54 visibly pulsating
38:56 Mo alerted the cabin crew who arranged
38:59 for an ambulance to be ready and waiting
39:01 for her at the airport
39:04 the pacemaker was examined as she landed
39:07 and its data was found to be bizarrely
39:10 corrupted
39:11 once she was discharged from hospital
39:13 she received a detailed report from her
39:16 pacemakers manufacturer about what had
39:19 happened
39:20 inside the pacemaker's computer memory
39:23 data is stored in the form of bits often
39:27 referred to as ones and zeros one of
39:30 these crucial bits had inexplicably
39:33 flipped or reversed triggering the
39:35 pacemaker to shift in to backup mode and
39:39 restore her heart rate to a default
39:41 rhythm of 70 beats per minute
39:44 although Mo believed that radioactive
39:47 particles from solar flares caused the
39:50 issue with her device the link was never
39:53 approved and will never be proved since
39:56 these particles leave no measurable
39:58 fingerprints behind
40:00 a similar bit flip incident occurred
40:03 during a 2008 Qantas Airways flight over
40:06 Western Australia
40:08 the aircraft dropped hundreds of feet
40:11 twice within 10 minutes resulting in
40:14 injuries to dozens of passengers on
40:17 board
40:18 some suffered bruises to their limbs
40:20 While others struck their hands against
40:23 the cabin's interior once again the link
40:26 was never proven
40:28 similarly for decades the phenomenon of
40:32 U.S military mines exploding in Vietnam
40:35 due to solar effects remained a mystery
40:39 until someone finally connected the dots
40:43 a new study accepted by the Journal
40:46 space weather has proposed a possible
40:49 explanation for this enigmatic wartime
40:52 event
40:54 according to the researchers the mines
40:56 were likely triggered by a powerful
40:59 solar storm which activated the mine's
41:02 magnetic sensors and resulted in
41:05 unexpected explosions
41:08 many of these mines that a detonated
41:10 randomly were classified as magnetic
41:13 influence sea mines designed to detect
41:17 alterations in the magnetic field caused
41:20 by passing ships
41:22 in the days leading up to the explosions
41:25 a sunspot region known as
41:28 mr-11976 Unleashed a series of brilliant
41:32 flares energetic particles and
41:35 earth-directed ejecta
41:37 the coronal mass ejection from the Sun
41:40 reached Earth in just 14.6 hours
41:45 it was an incredible coincidence that
41:49 baffled military historians and
41:51 scientists alike
41:54 Global radio blackouts and radiation
41:57 storms in the upper atmosphere are also
42:00 not uncommon consequences of severe
42:03 x-class flares
42:06 additionally extensive mobile phone
42:09 outages and Transformer explosions have
42:12 been reported in regions affected by
42:15 strong flares in the past
42:18 disruptions can hamper satellite
42:21 operations interrupt radio
42:23 communications and pose a risk to
42:27 astronauts in space
42:29 imagine astronauts standing on the
42:32 moon's surface focused on their mission
42:35 conducting experiments taking samples
42:38 but suddenly the Tranquility is
42:41 shattered as a burst of energy erupts
42:45 from the Sun a coronal mass ejection the
42:49 moon lacking a significant atmosphere
42:52 and a global magnetic field like Earths
42:55 offers minimal protection against these
42:58 intense space weather events
43:01 these lethal radiation doses could pose
43:04 both immediate and long-term health
43:07 risks to the astronauts potentially
43:09 leading to radiation sickness and an
43:12 elevated risk of cancer over time
43:16 in such a crucial scenario the lunar
43:19 module would serve as their sole Refuge
43:22 these structures were designed to
43:24 withstand the normal radiation levels
43:27 encountered on the moon during their
43:29 missions however with no other option
43:33 and the sudden occurrence of a solar
43:35 storm might compel the crew to seek
43:38 shelter within the most shielded
43:40 sections of their habitat
43:43 fortunately the Apollo missions did not
43:46 encounter such extreme solar events they
43:50 were meticulously scheduled to avoid
43:53 periods of heightened solar activity
43:56 however as WE peer into the future of
43:59 space exploration including extended
44:03 lunar or Martian missions comprehending
44:06 and mitigating the risks posed by space
44:09 weather events like solar storms would
44:12 be essential developing Advanced
44:15 radiation shielding and early Warning
44:18 Systems will stand as crucial elements
44:21 in ensuring the safety and success of
44:24 astronauts embarking on these remarkable
44:27 Journeys beyond our planet
44:29 as for astronauts aboard the
44:32 International Space Station which has
44:34 been orbiting Earth since the year 2000
44:37 NASA made sure the station is heavily
44:41 shielded
44:42 Additionally the ISS orbits within
44:45 Earth's protective magnetic field
44:48 nevertheless despite our preparations
44:51 the reality is that Earth's magnetic
44:55 field strength has gradually declined
44:57 over the past 200 years
45:00 weakening by approximately 10 percent
45:03 during this period
45:05 this trend has sparked several concerns
45:08 among scientists about the potential
45:11 implications for our planet's defense
45:13 against future solar storms
45:17 if Earth's magnetic field continues to
45:21 weaken it may reach a juncture where it
45:24 becomes less effective in safeguarding
45:27 our planet from these rapidly
45:29 accelerated charged solar particles
45:33 Magnetic storms of the same level could
45:36 become more severe and pose greater
45:39 challenges to our technological
45:41 infrastructure
45:43 therefore today it's more important than
45:47 ever to predict solar storms in advance
45:49 and know when the next big flare may
45:53 occur
45:54 scientists and astrophysicists posit
45:57 that by seeking Insight from the sun's
46:00 surface itself we can uncover valuable
46:03 Clues to predict solar storms
46:06 because intriguingly our sun exhibits a
46:10 fascinating long-term pattern that
46:13 appears to come and go not randomly but
46:16 with a striking consistency
46:19 this pattern created by the sun spots
46:22 themselves is called the sunspot cycle
46:25 and a single cycle lasts for about 11
46:28 years
46:30 it can be as short as eight or as long
46:33 as 14 years and it can vary dramatically
46:37 in intensity
46:39 during one cycle the number of sunspots
46:43 a good indicator of solar activity goes
46:46 from low to high and back down to low
46:50 solar minimum represents a time when
46:54 Sunspot numbers are relatively low
46:57 and solar maximum represents a period
47:00 when Sunspot numbers are relatively High
47:03 during this cycle the location of the
47:06 sunspots also changes they tend to be
47:09 situated at middle latitudes during
47:12 solar maximum gradually shifting closer
47:16 to the Equator as the sun approaches
47:18 solar minimum at times of solar minimum
47:22 sunspots may even be absent from
47:25 observation while solar maximum can
47:28 witness the presence of multiple
47:30 sunspots simultaneously
47:33 the number of sunspots is important
47:35 because sun spots are the visual markers
47:38 of where powerful magnetic fields can
47:41 emerge from the sun's interior
47:44 as discussed these magnetic fields power
47:47 solar flares and coronal mass ejections
47:51 which can affect Earth and other objects
47:54 in the solar system as these sunspots
47:57 increase on the sun's surface so does
48:00 the frequency and severity of flares and
48:03 CMEs
48:05 the sun's 11-year cycle is a symptom of
48:08 a longer 22-year cycle called the solar
48:12 cycle or hail cycle which affects the
48:15 sun's magnetic fields
48:17 every 11 years the sun's poles flip
48:20 North becomes South and South becomes
48:24 North
48:25 consequently every 22 years the poles
48:28 return to their original position where
48:31 the cycle began
48:34 the flip is due to the complex movement
48:37 of magnetic fields inside the Sun that
48:40 are constantly stretching twisting and
48:43 Crossing as solar material bubbles up
48:46 from the sun's core
48:48 but the exact pattern of movements is
48:51 not yet mapped out
48:54 how's the Sunspot Cycle follows a
48:56 similar pattern regardless of the
48:58 orientation of the poles it only takes
49:01 half as long as the solar cycle
49:04 the two cycles are different but the 11
49:07 year sunspot cycle is what is often
49:10 referred to as the solar cycle
49:13 right now the sun is approaching solar
49:16 maximum which is the current solar cycle
49:19 25.
49:21 so flares and CMEs are more common than
49:25 they were a few years ago
49:27 consequently you might have come across
49:29 numerous news articles discussing these
49:32 phenomena
49:34 NASA even maintains a dedicated website
49:37 where you can keep track of them
49:39 yourself
49:41 the current solar cycle is expected to
49:44 Peak in 2025.
49:47 recognizing this urgency explains why
49:50 NASA and governments around the world
49:52 are taking space weather forecasts
49:55 seriously
49:57 and to avoid being caught off guard they
50:00 have declared space weather forecasts to
50:03 be a priority in the development of
50:05 science
50:06 the UK government for instance has
50:09 listed severe space weather as one of
50:12 the highest priority natural hazards in
50:15 the National risk register
50:17 solar storms are now included on the UK
50:20 National risk register of civil
50:23 emergencies and the meteorological
50:25 office is tasked with monitoring and
50:28 forecasting space weather events
50:31 the perceived risks associated with
50:33 space weather events are rated as having
50:36 high impact and likelihood
50:39 in response UK scientists are currently
50:42 working on developing the first space
50:45 weather monitor the country has seen in
50:48 a generation
50:49 the monitor will help scientists predict
50:52 when and where solar storms will occur
50:55 allowing them to warn and protect Earth
50:58 from the potential damage caused by
51:01 these events
51:02 in the UK the National Grid has been
51:05 replacing high voltage Transformers with
51:08 newer designs which are more resilient
51:11 to extracurrent surges the strategy in
51:15 the UK is that if a large CME is
51:18 expected they will turn on as much of
51:20 the 8 000 kilometers of UK power lines
51:23 as possible to dump the extra energy
51:26 over the entire system and drain it back
51:29 to Earth
51:30 rather than allowing it to overload a
51:33 few Key System areas costing costly and
51:36 lengthy repairs
51:38 in the United States the government has
51:41 taken substantial measures to prepare
51:43 for the potential impact of a Carrington
51:46 level solar storm
51:48 one of the central elements of these
51:51 efforts is the establishment of
51:53 comprehensive monitoring and early
51:55 warning systems
51:57 the National Oceanic and Atmospheric
52:00 Administration NOAA operates the space
52:04 weather prediction center
52:06 swpc in Boulder Colorado
52:09 this Center closely monitors solar
52:12 activity and issues alerts and forecasts
52:15 regarding potential solar storms
52:18 detected solar storm information is then
52:22 disseminated to various user groups
52:24 ranging from Airlines and the electric
52:26 power grid to emergency managers and the
52:30 aviation satellite community
52:32 the United States Geological Survey USGS
52:36 monitors the Earth's magnetic field at
52:40 14 ground-based observatories positioned
52:43 across the United States and its
52:45 territories
52:47 scientists continuously monitor the
52:50 geomagnetic field throughout the nation
52:53 providing information on magnetic storm
52:56 intensity
52:57 remarkably some USGS observatories have
53:01 been operational for over a century
53:05 in 2016 President Obama signed an
53:09 executive order aimed at orchestrating
53:11 Endeavors to ready the nation for space
53:14 weather incidents
53:16 this directive's objective is to curtail
53:19 economic losses Safeguard lives and
53:23 enhance National Security
53:25 it mandates the establishment of
53:28 comprehensive Nationwide response and
53:30 Recovery strategies an interweaving
53:33 Technologies designed to alleviate the
53:36 impacts of space weather phenomena
53:39 these measures undertaken are necessary
53:41 since comparing the economic impact of
53:45 solar storms to some famous natural
53:47 disasters in the United States alone
53:50 provides a stark realization of their
53:53 potential consequences
53:55 the cost associated with solar storms
53:58 could surpass that of the top 10 natural
54:01 disasters in the U.S combined including
54:05 events like Hurricane Katrina hurricane
54:08 Harvey and wildfires that have ravaged
54:11 the nation in recent years
54:14 natural disasters have never known
54:16 borders drawn by humans and in the end
54:19 it's all down to the individual
54:22 countries and their power companies to
54:24 make sure that when the once in a
54:27 hundred years CME comes along the lights
54:30 won't go out
54:31 it is truly said that no Nation can ever
54:35 be fully prepared for such a violent
54:38 scenario
54:40 scientists worry that one big problem
54:42 with solar flares is that it has no
54:45 upper limit making them an unpredictable
54:48 and formidable force to reckon with
54:52 the sheer scale of Destruction it can
54:55 unleash is beyond human comprehension
54:58 an x-class flare can trigger one of the
55:02 largest CMEs that can blast a billion
55:05 tons of matter out at speeds of 3 000
55:08 kilometers per second or 1900 miles per
55:12 second
55:13 a large enough CME can also expand in
55:17 size as it propagates away from the Sun
55:19 and then quadruple in size by the time
55:23 it reaches our planet
55:24 a single CME is able to hold and release
55:28 energy equal to 10 billion one Megaton
55:32 nuclear bombs or equal to millions of
55:35 years worth of electricity usage by
55:38 Humanity in just a few weeks
55:41 according to NASA the sun generates
55:44 anything from one CME every week to
55:48 several per day depending on where we
55:51 are in this 11-year cycle of activity
55:55 currently each year Earth experiences
55:58 thousands of solar flares and CMEs on
56:01 average
56:02 thanks to Earth's strong magnetic field
56:05 or magnetosphere the majority of CMEs
56:09 pass by our planet unnoticed by the
56:12 general population or we avoid them
56:14 completely by not being in their path
56:18 among the various solar flares produced
56:21 by the sun most are small C-Class and
56:25 m-class flares
56:26 however every once in a while we do
56:29 encounter x-class flares accompanied by
56:33 large coronal mass ejections most of the
56:36 time we have been lucky not to be in
56:39 their path
56:40 estimates vary but many believe that a
56:44 Carrington level event might strike
56:46 Earth on average once every 150 years
56:51 over 160 years have passed since then by
56:55 some measures we are overdue
56:58 the question has now shifted from if to
57:01 rather when
57:03 the day a Carrington level event strikes
57:06 Our Generation could be blindsided by an
57:10 unprecedented catastrophe for which we
57:13 are currently utterly unprepared
57:19 in the world we live in today we have
57:22 thousands of important satellites
57:25 orbiting above
57:27 2022 despite warnings from space
57:31 organizations many SpaceX satellites
57:34 fell from the sky during solar flares
57:37 they have lost 50 million dollars worth
57:40 of satellites to geomagnetic storms
57:44 in the future too if a large enough
57:47 storm strikes Satellites May plummet
57:50 from the sky due to lack of control and
57:53 orbital guidance
57:55 on the ground the potential damage to
57:58 North America's power grid would be
58:00 unimaginable
58:02 Transformers which are extremely
58:04 expensive to build make Power
58:07 transmission possible however when a CME
58:11 sweeps across earth these towers
58:14 designed to handle AC currents are
58:17 instead flooded with DC currents
58:20 this may cause them to overheat melt or
58:24 even explode as was the case in 1989 in
58:28 Quebec Canada
58:30 Life as we know it would come to a halt
58:34 cellular towers would begin to fail
58:36 anything reliant on local power from
58:40 your cell phone charger to critical
58:42 infrastructure would become inoperable
58:45 this includes Last Mile Communications
58:48 as well such as cable TV or Internet
58:52 in the absence of lighting certain
58:55 individuals might find a window of
58:57 opportunity to engage in disruptive
59:00 activities
59:01 you may be familiar with accounts of
59:03 increased theft and burglaries occurring
59:06 during power outages
59:08 the absence of usual lights and security
59:11 systems would create a more conducive
59:13 environment for illicit actions to take
59:16 place
59:18 the usual sense of safety would
59:20 disappear once the streets that used to
59:23 be bustling with light become shadowy
59:25 alleys
59:27 unbridled Panic buying and widespread
59:30 looting from stores further exasperating
59:33 the challenges faced during such times
59:37 and irrespective of the balance on your
59:40 card its monetary value becomes zero as
59:44 ATMs would cease to function rendering
59:47 it temporarily inaccessible
59:50 the Contemporary economy would grind to
59:53 a halt in the absence of electricity
59:57 moreover in many cities water
60:00 distribution depends on electric pumps
60:03 if the power goes out water becomes
60:06 unavailable
60:07 plus imagine the turmoil at the
60:11 hospitals and other locations given that
60:14 the majority of our medical
60:15 infrastructure depends on electricity
60:18 and the internet
60:20 imagine the situation of the people who
60:23 would need critical life support systems
60:25 that are powered by electricity
60:28 hospitals could theoretically lose
60:30 access to patient information
60:33 military and Defense Forces rely heavily
60:36 on real-time communication for strategic
60:39 decision-making coordination between
60:42 units and sharing critical intelligence
60:45 solar storms can disrupt radio
60:48 frequencies and satellite communication
60:50 potentially leading to delays or even
60:54 failures in transmitting crucial
60:56 information
60:58 in this setting a soldier on the verge
61:01 of a life or death moment would be alone
61:04 devoid of any communication
61:07 the storm's impact would extend to
61:10 additional areas with approximately 10
61:14 000 airplanes navigating the sky's
61:17 simultaneously each reliant on GPS for
61:20 precision the prospect of their
61:23 navigation systems going blank would
61:25 mark an unprecedented catastrophe
61:29 while a fraction of flights might manage
61:31 to land safely a substantial number
61:34 would find themselves in Dire Straits
61:38 this upheaval might not be fleeting the
61:41 aftermath could leave a lasting scar
61:45 power grids could suffer irreparable
61:47 harm unless preemptively shut down to
61:51 Shield them from the oncoming storm
61:53 given the immense scale of some Power
61:56 Systems experts speculate that the worst
61:59 case scenario could necessitate up to a
62:02 decade for a full recovery
62:05 a separate 2008 report from the National
62:08 Academy of Sciences Nas theorized that a
62:12 moderatively severe geomagnetic storm
62:15 could leave a hundred thirty million
62:18 Americans without power
62:20 according to FEMA power grids on the
62:23 east and west coasts of America would be
62:25 hardest hit
62:28 furthermore it's interesting how natural
62:30 disasters often Trace back to solar
62:33 storms
62:34 researchers have noticed a pattern
62:37 earthquakes tend to Surge during times
62:40 of intense solar activity
62:43 this might explain the massive magnitude
62:46 9.1 earthquake in 2004 which not only
62:50 shook the ground but also triggered a
62:53 devastating tsunami in Indonesia the
62:56 impact was felt across India Thailand
62:59 Bangladesh the Maldives Sri Lanka and
63:03 Somalia
63:04 resulting in a staggering loss of life
63:07 over 283
63:10 000 people gone more than 14 000 missing
63:13 and more than a million left homeless
63:18 a few months earlier the sun had erupted
63:21 with a massive x-class solar flare
63:24 if we are not prepared the consequences
63:27 will be dire
63:29 The World At Large will be thrown into
63:32 chaos
63:33 because compared to the early 20th
63:36 century we are much more advanced and
63:39 dependent on electricity
63:42 scientists have been warning about this
63:44 for a long time
63:46 perhaps the present moment could be
63:49 opportune for prioritizing the
63:52 protection and investment of tax funds
63:54 into our electrical infrastructure
63:56 because in our modern world it isn't a
64:00 problem of the past it's a problem that
64:03 is more relevant today than ever before
64:07 we survived the recent pandemic by using
64:10 remote work Solutions but these tools
64:13 would be essentially useless in case of
64:16 a geomagnetic storm
64:18 the scale of the event would be unlike
64:21 anything Humanity would have ever
64:23 encountered
64:24 a moderately severe storm would cost the
64:28 U.S economy 2.6 trillion dollars in
64:31 total and Recovery could take up to 10
64:35 years as per an Nas report
64:38 in short a solar storm of a Carrington
64:42 level event would literally bring our
64:45 high-tech Society to its knees
64:48 dealing with space weather is no walk in
64:51 the park
64:52 and no matter how much we unravel no
64:56 matter how many various models foresee
64:58 various outcomes one lingering question
65:02 is always asked when will the next solar
65:06 storm strike
65:08 trying to predict when the next
65:10 Carrington level event will strike is
65:13 like aiming at a moving Target
65:16 though the estimates vary many experts
65:19 agree that people born after the 90s
65:22 will likely experience an extraordinary
65:25 solar storm at some point in their
65:28 future
65:29 as for exact timing it's a puzzle we're
65:32 still piecing together
65:36 the Space Age marked a new era in solar
65:39 astronomy
65:41 satellites like the solar maximum
65:43 Mission smm launched in the 1980s
65:47 provided an unprecedented view of solar
65:50 flares and eruptions in various
65:52 wavelengths
65:54 the solar and heliospheric Observatory
65:57 and the Solar Dynamics Observatory have
66:00 continued this Legacy
66:02 offering real-time insights into the
66:05 sun's magnetic activity solar wind and
66:09 other Dynamic processes
66:12 ready to face the raw power of an
66:15 x-class flare directed at our planet
66:18 NASA and NOAA are always on high alert
66:22 keeping a close watch on the Sun
66:25 NASA's heliophysics Fleet of spacecraft
66:28 has Our Stars surrounded giving us a
66:32 clearer picture of its activities
66:35 this comprehensive view helps scientists
66:39 predict and track space weather events
66:42 like flares and dramatic chronal Mass
66:45 ejections with greater accuracy
66:48 with a heads up governments and
66:51 companies can take steps to protect
66:53 their Tech and prevent worst case
66:55 scenarios
66:57 for years scientists at Nasa have wanted
67:00 to get up close and personal with the
67:02 sun and now they're doing just that with
67:06 the Parker solar probe set to give us
67:09 unprecedented insights
67:12 by 2025 it's supposed to make actual
67:16 contact with the sun blazing at speeds
67:19 up to 690
67:21 000 kilometers per hour or 430 000 miles
67:25 per hour making it the fastest thing
67:28 humans have ever built
67:31 Beyond this the probe has already flown
67:34 close enough to the Sun to detect the
67:37 fine structure of the solar wind close
67:40 to where it is generated at the sun's
67:42 surface revealing details that are lost
67:45 as the wind exits the corona as a
67:48 uniform blast of charged particles
67:52 NASA also envisions a future where solar
67:56 storm Sirens could be employed sounding
68:00 alarms and power stations and satellite
68:02 control centers worldwide similar to how
68:06 tornado sirens alert communities to
68:09 impending terrestrial weather events
68:11 to achieve this they are developing a
68:14 model known as dagger deep learning
68:18 geomagnetic perturbation
68:20 this model employs artificial
68:23 intelligence to analyze data from
68:25 spacecraft observations of the solar
68:28 wind the researchers have applied an AI
68:31 method called Deep learning which trains
68:34 computers to recognize patterns based on
68:37 previous samples and can provide a lead
68:40 time of 30 minutes for an impending
68:42 solar storm anywhere on Earth giving
68:46 enough time for critical systems to be
68:48 shut down or protected dagger was put to
68:52 the test using data from two geomagnetic
68:56 storms that occurred in August 2011 and
69:00 March 2015.
69:02 impressively in each case daggers
69:05 swiftly and accurately predicted the
69:07 storm's Global impact
69:09 the method's Precision is such that the
69:12 model can generate predictions in less
69:15 than a second with updates provided
69:17 every minute according to the team's
69:20 findings
69:21 but it's captivating to think that
69:23 despite our technological leaps we're
69:26 still at the mercy of the celestial
69:29 eruptions there's virtually nothing we
69:32 can do to physically halt a massive
69:35 solar flare hurtling towards us
69:38 however despite the obvious challenges
69:41 it's not all gloom and doom unlike the
69:45 occurrences in 1859 1921 1989 and 2012
69:52 we are in a much much better position to
69:55 anticipate a geomagnetic Storm's arrival
69:59 but how we respond to this warning would
70:02 shape the aftermath of such an event a
70:05 Swift and coordinated response would
70:08 involve temporarily taking offline any
70:11 systems that might be susceptible to
70:14 damage during the event
70:16 according to experts in this best case
70:19 scenario a Carrington level event might
70:22 cause about a week of significant
70:25 disruption worldwide
70:27 on the other hand there's the worst case
70:30 scenario in which we're ill-prepared or
70:33 caught unaware by a sudden Carrington
70:35 level event
70:37 the result would be one of the most
70:39 massive blackouts in history a
70:42 simultaneous loss of power communication
70:45 breakdowns and the collapse of most
70:48 modern technology
70:50 we're entering the riskiest phase of
70:53 solar activity in this whole decade the
70:57 solar maximum of the year 2025.
71:01 what if a really strong solar storm
71:04 happens soon will we have any options
71:09 on a personal level it's wise to take
71:12 precautions outlined by the U.S
71:15 government's National Weather Service in
71:17 case of an emergency
71:19 it includes keeping your car's gas tank
71:22 at least half full as gas stations rely
71:26 on electricity to operate pumps
71:29 store extra batteries for your phone or
71:32 consider getting a solar powered or hand
71:35 crank charger
71:36 if you have a traditional landline phone
71:39 ensure you have a non-cordless receiver
71:43 this type of phone will work even
71:46 without power
71:48 regularly duplicate critical digital
71:51 data and information and establish a
71:54 family contact sheet with an out of town
71:56 contact who could assist in connecting
71:59 family members during an emergency
72:02 some key actions involve staying indoors
72:06 following local authorities instructions
72:09 and contributing to your community
72:12 by doing this collectively we can Shield
72:15 ourselves from even the most severe
72:18 storms to some extent
72:21 after a week normalcy could gradually
72:24 return
72:25 if we manage the disaster effectively
72:28 the aftermath could be considerably less
72:31 costly compared to other natural
72:34 calamities like hurricanes or
72:36 earthquakes
72:37 nevertheless preparedness is Paramount
72:42 asteroids heading for the Earth are
72:45 always kept an eye on
72:47 these solar storms are quiet they strike
72:52 in the darkness and pose a threat to the
72:55 entire modern civilization
72:58 in addition to the familiar natural
73:00 disasters such as Cyclones Rising floods
73:04 and volcanic eruptions there is a new
73:07 type of danger up there in space one
73:10 we've recently discovered
73:12 space weather should be more concerning
73:15 than it is
73:16 we are destined to share our existence
73:19 with our son for countless more
73:22 Millennia and with each new day as the
73:26 sun rises above the horizon
73:28 it's just another reminder that we are
73:32 living with a star
