00:00A solar storm is crashing into Earth like a cosmic tsunami.
00:05First, the atmosphere ignites, sparking massive auroras.
00:09High-energy radiation slams into the surface, frying power grids,
00:13turning lights off across continents, and knocking out satellites.
00:18Planes lose navigation.
00:20Radios go silent.
00:22GPS systems crash.
00:24Radiation levels spike dangerously.
00:27Communication collapses, emergency services scramble in the darkness,
00:31and chaos spreads as people struggle to cope.
00:34Solar particles start to strip away the very air we breathe,
00:37slowly peeling off our atmosphere.
00:40Soon, Earth will become a harsh and hostile place.
00:43That's what solar activity can do to our planet and its inhabitants
00:47if we didn't have a protective shield called the magnetosphere.
00:52But even with this barrier, we're still in for serious problems.
00:58A mysterious 100-year solar cycle may have just restarted,
01:03and it could mean decades of dangerous space weather.
01:06New research suggests that the unexpected intensity of the ongoing solar maximum
01:11may be partly tied to a lesser-known 100-year solar cycle.
01:16If the sun is indeed entering its villain arc,
01:20solar activity could spike even further in the coming decades.
01:23It means more solar flares, more chances of them messing with satellites,
01:28and way more of those crazy northern lights people keep posting on Instagram.
01:33Sure, not everyone's buying it.
01:35Some space nerds want more proof before jumping on this solar hype train.
01:40Let's break it all down into detail first.
01:44The sun goes through a kind of mood swing every 11 years.
01:48This is called the solar cycle.
01:50It starts off at a solar minimum, which is pretty chill,
01:54then slowly gets rowdy.
01:56We're talking sunspots, solar flares, and other fiery drama.
02:01Once we reach solar maximum, the situation starts to calm down again.
02:06The sun gets sunspots, dark patches on its surface,
02:10like the freckles we humans have,
02:12when its magnetic field starts flipping out.
02:15Literally.
02:16The sun's magnetic field completely flips during peak solar drama.
02:20Scientists track how many of these spots show up
02:23to measure how spicy the sun is getting.
02:26But wait, plot twist, there are other cycles too,
02:29like the hail cycle, which occurs around every 22 years.
02:33This cycle controls how magnetic fields move across the sun.
02:38Plus, way back in history,
02:40there were moments when the sun basically went on do-not-disturb mode.
02:44During the maunder minimum,
02:46our star was basically in sleep mode for 70 years.
02:50In other words, the sun might be entering a new extra phase,
02:55and things could get dramatic.
02:57On the bright side, that means more auroras.
03:00At the same time, it could also cause issues for satellites,
03:04GPS, and other stuff we rely on.
03:07Ugh, let's just hope it doesn't mess with YouTube.
03:11This extra phase is called the Centennial-Gleisberg Cycle.
03:15It's basically the sun's
03:17once-every-100-years-I-do-something-weird moment.
03:21Scientists think it messes with how intense sunspot cycles get.
03:25No one has fully worked out how this cycle works yet,
03:29but some low-key sloshing of magnetic fields inside the sun might be causing it.
03:34Yep, I did say sloshing.
03:36Like a giant cosmic smoothie.
03:39A recent study from March 2025 claims that the CGC might have just hit restart.
03:46That could explain why this current solar maximum,
03:49the sun's drama phase that started in early 2024,
03:53is being so weird and unpredictable.
03:55How did researchers figure this out?
03:58They looked at something called proton flux.
04:01Basically, it's how many positively charged particles
04:04are flying around in Earth's radiation belt.
04:06There are two of these belts,
04:09shaped like donuts that wrap around Earth,
04:11full of particles from the sun.
04:13The thing is, when the sun is active,
04:16our upper atmosphere swells,
04:18which makes the inner radiation belt lose some of those protons.
04:21And when the sun is chill,
04:23proton numbers go up again.
04:25So those protons have been increasing for like 20 years,
04:29but just started to drop in the past year.
04:32Which basically screams,
04:34CGC has just hit minimum.
04:36Time for the sun to crank it back up.
04:40The data came from NOAA satellites
04:43that flew through the South Atlantic anomaly,
04:45which is like the Bermuda Triangle of space.
04:48It's this bizarre zone over South America,
04:51where Earth's magnetic field is weaker,
04:53and space radiation gets closer to Earth.
04:56This area is perfect for observing proton activity
05:00without sending a satellite into the actual danger zone.
05:04So, right now,
05:06we're probably nearing the end of the sun's current chaos phase,
05:10aka the peak of Solar Cycle 25.
05:14Back in May 2024,
05:16it hit us with one of the craziest geomagnetic storms in 500 years or so.
05:20And yes,
05:21that means super bright auroras lighting up skies all over the world,
05:26even in places that usually only get clouds and vibes.
05:29But the scariest thing?
05:31This wasn't supposed to happen.
05:34During the last cycle,
05:35the sun was oddly calm.
05:37So NASA and NOAA looked at that
05:40and thought that the next solar cycle would probably be the same.
05:44No biggie.
05:45Well,
05:45they were wrong.
05:46And they even admitted it.
05:49Now,
05:50scientists think that SC24's quiet phase
05:53was because of the Centennial-Gleisberg cycle being at its low point.
05:57That probably made it the quietest sunspot cycle in 100 years.
06:01So now that SC25 is lit again,
06:05pretty literally,
06:06it might just mean the sun is back to doing what it normally does,
06:10being a little chaotic and wild.
06:13Recent studies think the CGC minimum is finally over.
06:17That would explain why the current solar activity is turning up the heat
06:21and why the last one felt like a cosmic snooze.
06:26An even cooler thing is that a 2024 study
06:29used AI to analyze sunspot patterns
06:32and found that CGC might be messing with our forecasts
06:35more than we thought.
06:37And if this long-term mood swing of our star is really back on the rise,
06:42future solar cycles could be just as wild as the one we're in now,
06:46or even wilder.
06:48After all,
06:49we've just passed the CGC's low-energy mode
06:51and we won't hit the next maximum for another 40 to 50 years,
06:56around solar cycle 28.
06:58That's a few decades away,
06:59but the sun's already throwing tantrums.
07:02The scariest part is that future solar activity
07:05might be twice as intense as what we're seeing now.
07:08You might be wondering right now,
07:10why should I care?
07:12Well, because when the sun freaks out,
07:14it messes with our stuff,
07:15especially in space.
07:18Satellites get dragged out of orbit
07:19because Earth's upper atmosphere
07:21literally puffs up like a marshmallow in a microwave
07:24when solar activity spikes.
07:27And this has already happened to a few spacecraft recently.
07:30And with tons of private satellite mega constellations
07:33like Starlink and its squad,
07:35the risk goes way up.
07:37There are some,
07:38even though those are few,
07:40that might not be ready
07:41for a full-blown sunrage event.
07:44Time to wear SPF 100 for your satellites.
07:50Astronauts are also at risk.
07:51More solar flares mean more radiation
07:53and more danger for humans in orbit.
07:56At the same time,
07:57more space tourists and missions
07:59mean more people potentially
08:01in the sun's cosmic splash zone.
08:03At the same time,
08:05not everyone is buying into the whole
08:07CGC is back and ready to party theory.
08:10Some experts say it's a cool theory,
08:12but we shouldn't get carried away.
08:13The thing is,
08:14the proton flux,
08:15those space particles we've been watching,
08:18only started dropping last year.
08:20That's not a lot of time.
08:21It might just be a short-term dip,
08:24like the sun sneezed
08:25and now everyone's freaking out.
08:27Also,
08:28we've only been able to track this stuff properly
08:30for 30 to 40 years or so,
08:32which is basically nothing in sun time.
08:35So there's no solid before and after data
08:38to compare CGC cycles and say,
08:40yep, this is definitely a pattern.
08:43Plus, the CGC itself is kind of mysterious.
08:47Like no one can fully agree on what it even is,
08:50how it works or how much it actually messes
08:53with sunspot cycles.
08:55It's like the Bigfoot of solar science,
08:58blurry, weird,
08:59and causing drama in group chats.
09:01But even skeptics admit
09:02that the new study is interesting
09:04and well-intentioned,
09:06and that it might help us predict
09:07future solar cycles better.
09:09We just need more time,
09:11more data,
09:12and better definition of the CGC
09:14before we treat it like
09:16the ultimate weather app for the sun.
09:20A large space probe is nearing the sun.
09:23The terrifying heat of the star
09:25begins to melt the shell of the spacecraft.
09:28Another moment,
09:29and the probe bursts into flames.
09:31In no time,
09:32it disintegrates in a powerful explosion.
09:35Ah, what a sad ending.
09:37If it were true,
09:38it was not a probe.
09:40It was a comet known as 3I Atlas.
09:43And despite everything people say,
09:45it's still intact and thriving.
09:48The thing is,
09:49there is a rumor online
09:50saying that comet 3I Atlas
09:52exploded when it got closest to the sun.
09:55But astronomers say this is not true.
09:58There was no explosion.
10:00And the comet's nucleus
10:01still looks whole and undamaged.
10:04Which is kind of surprising,
10:05since comets that pass very close to the sun
10:08usually go through some serious changes.
10:11You see,
10:12comets are made of a mix of ice,
10:14dust, and rocky material.
10:16Which is why they're often called
10:17dirty snowballs.
10:19So,
10:20when they come close to the sun,
10:21the intense heat from our star
10:23makes their ice turn into gas.
10:25This new gas can burst out in huge jets,
10:28form a cloud around the comet
10:30called a coma,
10:31and or be pushed away into a long tail.
10:34Sunlight makes all of these parts
10:36shine more brightly.
10:38And even people with small or simple telescopes
10:40can study the comet
10:42if the viewing conditions are good.
10:43But,
10:44aside from being a breathtaking view,
10:46such a close approach
10:48can break off pieces of a comet
10:49or even tear its whole nucleus apart.
10:53Now,
10:54it's true that some comets
10:55survive this process.
10:56But many,
10:57especially small ones,
10:59or comets entering the inner solar system
11:01for the first time,
11:02break into pieces
11:03or disappear completely.
11:05Well,
11:063I Atlas acted differently.
11:09So there.
11:09It reached its closest point to the sun
11:11on October 29, 2025.
11:14This point is called the Perhelion.
11:16At that moment,
11:18the comet was about 130 million miles
11:20from the sun.
11:21That's about one and a half times
11:23the distance between the sun and our planet.
11:25The comet was also on the opposite side
11:28of the sun from Earth.
11:29So,
11:29the star was blocking it from our view,
11:31and we couldn't see the comet.
11:33Anyway,
11:34even though 3I Atlas could
11:36hypothetically break apart
11:38or release lots of fragments,
11:40it didn't.
11:41The nucleus stayed intact.
11:43And this made the comet's behavior
11:44even more unusual
11:46and interesting to scientists.
11:48They looked closely at the new photos
11:50and said everything looked normal.
11:53Now,
11:53interestingly,
11:54the day before,
11:55some people thought the comet
11:57had broken into pieces
11:58after it came out
11:59from behind the far side of the sun.
12:01This idea became popular
12:03after a blog post said
12:05the comet had lost a lot of mass.
12:07So,
12:08to make this claim,
12:09the blog used photos
12:10taken on November 9th
12:12by two small telescopes in Spain.
12:14The pictures show jets of gas
12:16coming out of the comet.
12:18The scientists used this
12:19to estimate how much material
12:21was coming off the comet,
12:23claiming that it should have
12:24broken into at least 16 pieces.
12:26However,
12:27many scientists have questioned
12:29this statement.
12:30Most researchers say
12:31there's no proof
12:32that the comet exploded.
12:34One scientist who studies the comet
12:36says that all the images
12:37he had seen
12:38showed a completely normal,
12:40healthy comet.
12:41There's no sign
12:42that the main body
12:43of the comet
12:43has broken apart.
12:45Still,
12:46now that the comet
12:47is coming back into view,
12:49astronomers are watching it
12:50very carefully.
12:51They want to learn more
12:52about the comet's materials
12:54and structure.
12:55Right now,
12:56if you look at it from Earth,
12:57the comet seems to be
12:59slowly moving higher
13:00in the eastern sky.
13:01If the weather is good,
13:03people in many parts
13:04of the northern hemisphere
13:05can see it
13:06with a small telescope,
13:07like this one
13:08with a 6-inch lens.
13:10And many do
13:11pay attention to the comet.
13:12Since it was discovered in July,
13:14it has become the center
13:16of many curious ideas.
13:18Some people are sure
13:19that the comet,
13:20which comes from
13:21outside our solar system
13:22and might be
13:23more than 7 billion years old,
13:25could be a probe
13:26sent by a different civilization.
13:28Now,
13:29most astronomers
13:30strongly disagree,
13:31of course.
13:32They believe the comet
13:33is completely natural
13:34and comes from
13:35another star system
13:36somewhere in the Milky Way.
13:38And this
13:39is actually exciting.
13:41Comet 3I Atlas
13:42is only the third
13:43interstellar comet
13:44ever seen,
13:45and it is the largest
13:47one of its kind.
13:48Before,
13:49it was comet 2I Borisov
13:51that passed through
13:52in 2019,
13:53and Oumuamua,
13:55a weird and long-aided object
13:56that appeared in 2017.
13:58But 3I Atlas,
14:00with its up to
14:013.5-mile nucleus,
14:03dwarfs Oumuamua,
14:04which was just
14:05a quarter-mile long,
14:07and Borisov,
14:08which is about
14:08three-tenths of a mile across.
14:11Plus,
14:123I Atlas may be
14:13the oldest comet
14:14humans have ever observed.
14:16Oumuamua is much younger,
14:18around 1 billion years old.
14:20It came from
14:20the galaxy's thin disk,
14:22where new stars
14:23are still being born.
14:24It was the first known object
14:26from another star system
14:28to pass through
14:28our solar system.
14:29Basically,
14:30our first interstellar guest.
14:32It was super-stretched out,
14:34about ten times longer
14:35than it was wide,
14:37unlike anything else
14:38we've spotted in space.
14:40As for 2I Borisov,
14:42it sits in between,
14:43at roughly
14:441.7 billion years old.
14:46It also came from
14:47the thin disk.
14:48It was the first
14:49confirmed comet
14:50to come from
14:51another star system.
14:52And it gave scientists
14:53a super-rare peek
14:54at what materials
14:56beyond our solar system
14:57were made of.
14:58Unlike the first
14:59interstellar visitor,
15:00Oumuamua,
15:01which looked more
15:02like an asteroid,
15:03Borisov behaved
15:04like a classic comet.
15:06It had a bright coma,
15:08a temporary fuzzy atmosphere
15:09of gas and dust
15:10forming around
15:11the comet's nucleus
15:12as it approaches the sun.
15:14Plus,
15:15it also had a long tail
15:17of dust and gas.
15:19Now,
15:192I Borisov
15:20is speeding away
15:21from the sun
15:21and will never return.
15:23But it allowed scientists
15:25to take a glimpse
15:26into the chemistry
15:27and history
15:27of distant worlds.
15:29Now,
15:30let's get back
15:31to comet 3I Atlas.
15:32It will pass
15:33closest to Earth
15:34on December 19th.
15:36Until then,
15:37scientists will make
15:37many more observations.
15:39People will also
15:40make many new claims
15:41about the comet,
15:42that's for sure.
15:43But it's best
15:44to be cautious
15:45and not believe
15:46everything immediately.
15:47By the way,
15:48even though you can't
15:49see this famous comet
15:50with your own eyes
15:51or with a regular telescope,
15:53hey,
15:54that's good news.
15:55A powerful telescope
15:56in Italy
15:56is streaming it live
15:58for free.
15:59Whoa.
16:00So anyone can actually
16:01watch this mysterious object
16:03as it passes by.
16:05Scientists think
16:05this comet weighs
16:06about 33 billion tons.
16:09That's a big number.
16:10How about we make
16:11a few comparisons?
16:12The Eiffel Tower
16:13weighs around 10,000 tons.
16:15So 33 billion tons
16:17is the same
16:19as 3.3 million Eiffel Towers.
16:22And if you decide
16:23to compare
16:24the space visitor
16:25to buildings,
16:26well,
16:2633 billion tons
16:27is about the same
16:28as the weight
16:29of several huge city areas
16:30made entirely
16:31of steel and concrete.
16:34Now,
16:343I Atlas
16:35was first noticed
16:36in July
16:36by NASA's
16:38Asteroid Terrestrial Impact
16:40Last Alert System,
16:41which,
16:42if you're paying attention,
16:43is where they got
16:44the nickname Atlas.
16:46Shortly after,
16:47NASA confirmed
16:48that the object
16:48wasn't from our solar system
16:50at all.
16:51Now,
16:51besides being huge,
16:523I Atlas
16:53is unusual
16:54in several other ways.
16:55As it moves
16:56through the solar system,
16:58it's releasing
16:58massive amounts
16:59of carbon dioxide
17:00and dust.
17:01So,
17:02this suggests
17:02that 3I Atlas
17:04is 3 to 5 orders
17:05of magnitude,
17:07which means
17:071,000 to 100,000 times
17:10more massive
17:11than the two other
17:12known interstellar visitors.
17:13Such an enormous difference
17:15is a real scientific mystery.
17:17It's also traveling
17:18incredibly fast,
17:20about 150,000 miles per hour,
17:23which is almost
17:23200 times
17:24the speed of sound.
17:26Hey,
17:26that will get you
17:27a speeding ticket.
17:28And unlike objects
17:29in our solar system,
17:31which follow curved paths
17:32because of gravity,
17:343I Atlas
17:34is moving
17:35on a nearly straight line.
17:37That alone
17:37makes it stand out.
17:39Now that the comet
17:40has moved past the sun,
17:42telescopes on Earth
17:43can see it again.
17:44Comet 3I Atlas
17:46is important to us
17:47because it's only
17:48the third interstellar visitor
17:50we've ever seen,
17:51and it may be
17:52the biggest
17:52and oldest one yet.
17:54And it didn't break apart
17:55near the sun
17:56like some other comets.
17:57By studying it,
17:59scientists can learn
18:00what materials exist
18:01in other star systems
18:02and better understand
18:04how comets,
18:04and even planets,
18:06form in our galaxy.
18:11In September 1859,
18:13scientists observed
18:15the first confirmed
18:16powerful solar flare.
18:18The sun threw
18:19a large amount
18:20of radiation,
18:21energy,
18:21and plasma material
18:22into space.
18:23This was a massive
18:24and devastating disaster,
18:26but it happened
18:2793 million miles away,
18:29so it probably
18:30wasn't such a big problem,
18:31right?
18:32Well,
18:32actually it was.
18:34A few hours
18:36after the flare
18:36was spotted,
18:37telegraph lines
18:38stopped working
18:39all over Europe
18:40and North America.
18:41Some of them sparked
18:42and caused fires.
18:44People realized
18:45that the sun
18:46was not only
18:47the source of light
18:48and warmth,
18:49but also danger.
18:50Scientists called that day
18:52the Carrington effect.
18:54The good news
18:55is that this happened
18:56in the middle
18:56of the 19th century
18:57and didn't cause
18:58serious problems
18:59for the planet.
19:00The bad news
19:01is that scientists
19:02are warning
19:03that in 2025,
19:04Earth will experience
19:05even more powerful
19:07solar storms
19:08caused by a
19:09coronal mass ejection.
19:10This is a giant
19:12cloud of plasma
19:13or charged gas.
19:14At one time,
19:15the sun can throw
19:16billions of tons
19:17of this material
19:18into space.
19:19Then,
19:19all this flies
19:20at high speed
19:21through space.
19:22Some of the material
19:23can reach our planet
19:24in 15 hours,
19:26the rest
19:26in a few days.
19:28During the journey,
19:29it captures
19:29and accelerates
19:30any charged particles
19:31encountered along the way.
19:33which increases
19:34its intensity
19:35and power.
19:35And then,
19:36this unstoppable
19:37array of energy
19:38crashes into
19:39our planet.
19:41It heats
19:41the upper layers
19:42of the atmosphere,
19:43increases its thickness,
19:45and disturbs
19:46the work of satellites.
19:47They slow down
19:48and lose altitude.
19:49Communication with satellites
19:51becomes unstable.
19:52GPS is buggy.
19:54Data is poorly transmitted.
19:56Also,
19:56solar-charged gas
19:58penetrates
19:58into our power grids,
20:00transformer booths,
20:01and stations.
20:01It leads to massive failures
20:03that ruin the work
20:04of the entire
20:05technological chain.
20:07A powerful solar attack
20:08on several power plants
20:10can trigger a power outage
20:12in a large city.
20:13The internet,
20:14phones,
20:14social services,
20:15networks,
20:16nothing will work.
20:17We may lose connection
20:18with each other.
20:19Many large companies
20:20would go bankrupt,
20:21and the planet
20:22may face economic crises.
20:24These are big problems,
20:26but not the most serious ones.
20:28Electric plants
20:29serve boiler houses
20:30and water-pumping stations.
20:32Solar storms
20:33could stop water
20:34from getting to our homes.
20:35You wouldn't be able
20:36to buy groceries
20:37in stores without cash.
20:39Of course,
20:39we can restore all this,
20:41but we'll have to live
20:42in the Iron Age
20:43for a while.
20:44But the worst thing
20:45is that a prolonged solar storm
20:47can suspend food production.
20:49For example,
20:50this year,
20:51a geomagnetic storm
20:52caused by solar storms
20:54shut down GPS satellites
20:56that are connected
20:56with modern tractors,
20:58so farmers couldn't work.
21:00What would happen
21:01if such storms
21:01happened every day
21:02for a year?
21:03We would probably
21:05start missing many items
21:06in supermarkets.
21:07Besides,
21:08maritime navigation
21:09also depends on satellites.
21:11Thanks to them,
21:12ships calculate
21:13the latitude
21:14and longitude
21:14of their location.
21:16If the satellites
21:17are damaged,
21:18ships may get lost
21:19in the ocean.
21:20Even whales
21:20get lost in the ocean
21:21during magnetic storms.
21:23Many birds
21:24navigate
21:24with the help
21:25of magnetic field
21:26during long flights
21:27to the south.
21:28So,
21:29not only people,
21:30but also animals
21:31may experience
21:32serious problems.
21:33Solar storms
21:34heat the upper layers
21:35of the Earth's atmosphere
21:36and thus
21:37make the air thicker.
21:38The movement
21:39of satellites
21:40slows down
21:40because of this
21:41air resistance.
21:42They lose altitude.
21:44And one of these
21:45satellites is Hubble.
21:46Yes,
21:47the very telescope
21:48that provides us
21:49with incredible
21:49pictures of space.
21:51Scientists say
21:52that it will fail
21:53much earlier
21:54because of solar attacks.
21:55You've probably heard
21:56on the news
21:57that solar activity
21:58has recently caused
21:59electromagnetic storms
22:01on Earth.
22:02But,
22:03fortunately,
22:03it hasn't affected
22:04our lives in any way.
22:06The only problem
22:07was headaches,
22:08high pressure,
22:09and mood swings
22:10during those storms.
22:11It seems like
22:12an ordinary thing,
22:13but scientists
22:14don't have a consensus
22:15on this topic.
22:16No one has proven
22:17exactly how and why
22:19magnetic storms
22:20affect our condition.
22:22Yes,
22:22during storms,
22:23the planet's atmosphere
22:24becomes less dense,
22:26and perhaps this
22:27affects our blood pressure,
22:28like it happens
22:29when the weather changes.
22:30So,
22:31people with
22:32cardiovascular system
22:33problems
22:33should be careful.
22:34But the effect
22:35on our nervous system,
22:36fortunately,
22:37is quite insignificant.
22:38It's possible
22:40that when people
22:40hear about
22:41a coming magnetic storm
22:42and feel unwell,
22:43they experience
22:44a placebo effect.
22:46But there's also
22:47good news.
22:48All these charged
22:49solar particles
22:50interact with atoms
22:51and molecules
22:52in Earth's atmosphere.
22:53This interaction
22:54leads to beautiful
22:55northern lights.
22:56It's good to spend
22:57some time away
22:57from your gadgets
22:58and look up
22:59at the sky sometimes.
23:01One of the biggest
23:02storms occurred
23:03on March 13,
23:041989.
23:05On March 10,
23:07the sun ejected
23:08a gigantic volume
23:09of coronal plasma.
23:10The amount of that
23:11material was the size
23:12of 36 Earths.
23:14The solar cloud
23:15was flying to us
23:16at a million miles per hour.
23:18And a couple of days later,
23:20it crashed
23:21into our planet's
23:21magnetic field.
23:23The collision
23:23caused a geomagnetic
23:25superstorm.
23:26People watched
23:27some of the brightest
23:27and most beautiful
23:28auroras in history.
23:30The light show
23:31covered most of the planet.
23:32But after a beautiful
23:33performance,
23:34problems followed.
23:36The solar storm
23:37was so powerful
23:38that it went through
23:39the atmosphere
23:40and reached Earth's surface.
23:42First,
23:42it disrupted
23:43the operation
23:44of satellites
23:44and then damaged
23:45electrical networks.
23:47For example,
23:48it destroyed a transformer
23:49at a nuclear power plant
23:51in New Jersey.
23:52Energy companies
23:53in Canada went down
23:54because of systems overloading.
23:56As a result,
23:57about 6 million people
23:58in northeastern Canada
23:59lost electricity
24:01for 9 hours.
24:02This was the largest
24:03power outage
24:04caused by a geomagnetic storm.
24:06Yeah,
24:07there were more
24:07powerful storms
24:08in the mid-19th
24:09and early 20th centuries,
24:11but the planet
24:12wasn't covered
24:12by so many power grids
24:14at that time.
24:15More powerful storms
24:16may occur in 2025.
24:18The question is,
24:19will we be ready for them?
24:21A careful study
24:22of solar activity
24:23can help us prepare.
24:24If we know in advance
24:26about an upcoming storm,
24:28then scientists
24:28can switch off
24:29some systems
24:30and turn them on
24:31afterward,
24:32theoretically.
24:33If the activity
24:34of the sun
24:34increases every year,
24:36then we'll have to
24:37come up with new,
24:38innovative ways
24:38to protect ourselves.
24:40Who knows?
24:41Maybe scientists
24:41will cover all
24:42our electrical appliances
24:44and stations
24:44with a layer
24:45of special
24:46protective material.
24:47Anyway,
24:48we must do
24:49everything possible
24:50not to harm
24:51Earth's magnetic field.
24:52Because if this shield
24:53disappears,
24:54the surface of our planet
24:55will resemble
24:56that of Mars.
24:58But what causes
24:59these solar storms
25:00and why do they
25:01affect us so much?
25:02Okay,
25:03imagine a guy
25:04with a nice hairstyle
25:05who goes to bed.
25:06In the morning,
25:07his head
25:08is a complete mess.
25:09The magnetic fields
25:11of the sun
25:11are similar
25:12to this tousled air.
25:13When the sun rotates,
25:15these fields burst,
25:16get tangled,
25:17stretch,
25:18and tear.
25:19At those moments,
25:20they release
25:20huge amounts
25:21of energy
25:22into space.
25:23This is not
25:24a problem
25:24for the sun
25:25as the fields
25:26are restored
25:26during the process
25:27called magnetic
25:28reconnection.
25:29Such emissions
25:30can cause trouble
25:31for the planets
25:32in our system.
25:33When magnetic
25:34reconnection happens,
25:35several phenomena
25:37can follow.
25:38One of them
25:38you've already
25:39heard about.
25:40It's a coronal
25:41mass ejection.
25:42But there's another
25:43terrible thing
25:43that the sun does
25:44and it's called
25:45solar flare.
25:47Imagine a bright
25:48burst of solar
25:49radiation
25:49containing
25:50electromagnetic waves,
25:52x-rays,
25:53radiation,
25:54and visible
25:54and ultraviolet light.
25:56During flares,
25:57the sun releases
25:58an enormous amount
25:59of this destructive energy
26:00and it spreads
26:02through space
26:02at the speed of light.
26:03It takes 8 minutes
26:05for this explosive wave
26:06to reach our planet.
26:08Fortunately,
26:09we don't get much damage
26:10from these flares
26:11because Earth's
26:12magnetic field
26:13and atmosphere
26:13protect us.
26:15Strong flares
26:15can disrupt radio waves
26:17in the upper atmosphere
26:18and affect the operation
26:19of satellites,
26:20but it's nothing critical.
26:22Another solar phenomenon
26:24is called
26:24a radiation storm.
26:26These are
26:27accelerated electrons
26:28and protons
26:29that move at a speed
26:30slightly less
26:31than the speed of light.
26:32Thanks to Earth's
26:33magnetic field,
26:34radiation storms
26:35don't harm our planet
26:36too much,
26:37but they pose a danger
26:38to astronauts
26:39and satellites.
26:40These particles
26:41can penetrate
26:42human tissues
26:43and lead to serious
26:44health problems
26:45in the way radiation does,
26:46but only if you're in space
26:48or flying a plane
26:49in the upper atmosphere.
26:50higher.
