Narrator: They're watching you.

More than 4,000 satellites Circle the earth.

Every day, they uncover New, mysterious phenomena

That defy explanation.

Forest horror -- hitler's Secret miracle weapons...

My god.

Wow! What a sight!

Narrator: ...Weird science On the west coast...

This has been one Of the biggest-kept secrets

Of the united states.

Narrator: ...And food delivery, Mad-dictator style.

Nelson: they drop everything You would need --

Water, vegetables, Oh, and live sheep.

Narrator: baffling phenomena, Mysteries from space.

What on earth are they?

April 24th, 2018.

Travelling at 17,000 Miles per hour over poland,

An earth-observation Satellite captures this image.

What's weird about this image Is that these big circles

Or wells, Whatever they are,

Are in this very symmetrical Kind of zigzag-y pattern.

The structures are kind Of shaped like amphitheaters.

They look like they're hollow.

If you zoom in, It gets even stranger

Because the walls To these things

Are enormously thick.

Narrator: analysis suggests These walls are

Around 15 feet in diameter.

It's strange because it doesn't Conform to anything you see

In modern agricultural life Or industrial life.

Walters: They look concrete, which Suggests to me 20th century.

It looks to me as if they have Some military purpose,

But it's not yet apparent to me What that might be.

Narrator: If these are military structures

From the last century, their Location could be significant.

Poland has always been A military highway for conquest.

Janulis: poland was at the heart Of world war 1, world war 2,

And the cold war.

It suggests to me that these Structures are related

To one of those time periods.

The question is which one.

**

Narrator: military historian Martin morgan

Has flown to warsaw And is driving into the forests

Of western poland To investigate.

Morgan: I'm very interested In what I'm going to find

At this compound.

It looks like it was built In this forest

With an intent To disguise the site.

So, maybe this thing was built For clandestine purposes.

Narrator: the image coordinates Guide morgan to an isolated area

20 miles east of poland's border With germany.

**

This is as far as I go In the car.

It's on foot from here.

**

Narrator: a quarter of a mile Into the forest,

Morgan reaches a clearing.

Well, here's something I didn't expect to see.

**

Narrator: the tracks are too Modern to be from world war 1,

Yet haven't been used For decades.

The fact that I'm seeing Railroad, I think, indicates

That this is not A cold war site

Because during the cold war, The soviet union

Extended very little in the way Of railroad line in poland.

So, I think this site Was developed by the germans.

**

Narrator: to enforce Their occupation of europe,

The nazis built railway lines Between key strategic points.

Morgan: When I see lines like this,

Especially in a forest In poland,

My thoughts automatically go To the way that railroads

Were used by the germans During the second world war.

Yes, they're moving weapons And equipment,

But they're also moving people.

Narrator: It was tracks like these

That carried millions of jews And other victims

To six extermination camps In poland

Including auschwitz-birkenau.

**

Packed inside windowless Cattle wagons,

Many are forced to pay For their journey.

It's chilling to stumble through The forest in western poland

And see tracks like this.

**

Narrator: Morgan continues towards

The site indicated On the satellite image.

Ah, look at this.

Well, I wasn't expecting To see buildings so soon.

**

Oh, man.

Wow! What a sight!

Narrator: For military expert morgan,

The structures are more evidence That this is a nazi site.

It's looking...Very german

Because of rebar- Reinforced concrete,

Brick-masonry construction.

I don't know if they were Holding sewage or water

Or oil or gasoline.

Whatever they were holding, They were holding a lot of it.

**

Narrator: morgan soon finds More evidence that suggests

Hundreds or thousands of people Once lived and worked here.

**

Look at this beast.

**

Not only is this Building massive,

But there are two smokestacks Out back.

They appear to be Over 100 feet tall.

So, this structure was powering A massive complex.

**

Oh, man, this place Is incredible.

**

Narrator: morgan recognizes Structures in the ceiling.

You can still see up here One, two, three, four --

Four separate coal bins.

This is a coal-fired steam plant

Capable of astonishing levels Of output.

Narrator: yet the structure's Connection to the giant circles

In the image remains elusive.

Exploring the woods Behind the power plant,

Morgan discovers The first tangible evidence

To their purpose.

Oh, yeah, look at that.

**

This is a range. It's a firing range.

**

Spent a lot of time On ranges in my time,

But this is not for rifles, Pistols, machine guns.

**

The thickness of the concrete Wall of the backstop

Appears to be four feet, Maybe five feet.

And look at all The scarring on it.

All the scarring is intense.

Narrator: whatever the nazis Were testing here, it was big.

Morgan: that's why this thing Is so monstrously overbuilt.

This is fascinating because

That means that this Could potentially

Just be one big outdoor Energetic-materials laboratory.

Where terrifying technology Was born.

And look at it now.

Nature's reclaiming it.

Narrator: morgan hopes The circular structures

Seen from space Will reveal the nature

Of the massive nazi weapon Being built here.

Wow!

Oh, my god!

**

Narrator: coming up,

Hitler's hidden compound Reveals its secrets...

What we've uncovered here is A death factory.

Standing here's A little bit creepy.

Narrator: ...And mad mussolini's Sky-diving mutton.

It seems utterly nuts

Taking a sheep, Putting a parachute on it,

And then throwing it Out of a plane.

**

Narrator: in the forests Of western poland,

Martin morgan has found What looks like a test site

For a giant nazi weapon.

Finally, he reaches The circular structure

Seen from space That led him here.

**

Oh, man.

This is so much beefier than I thought it was going to be.

There's so much concrete in it.

**

This is just one of five In the forest here.

Narrator: As morgan climbs the structure,

He learns that it doesn't Just rise from the forest floor,

It's dug deep into it.

Wow. Look at this thing.

**

Oh, my god.

Narrator: whatever was kept here Was considered so dangerous

That it had to be surrounded By concrete and buried deep.

Morgan: I'm beginning To think explosives.

All along the outer lip here, There are these metal fasteners.

There used to be a wooden roof On top of this.

That was in the event that there Was an explosion inside,

The roof would pop like a cork.

The silo would not be damaged, Only the roof would.

Narrator: the satellite image, It appears,

Has captured A giant nazi bomb factory.

Morgan: that would make sense.

Explosives are made at the Facility, tested at that range,

And then stored in these silos.

And when I think of germans And world war 2 and explosives,

I think of one compound. They called it hexogen.

We would call it rdx.

Narrator: Far more powerful than tnt,

The explosives kept here Would go on to be used

In two of the biggest Conventional bombs ever built,

Tall boy and grand slam.

Suddenly, standing here's A little bit creepy

Because the silos That stored this explosive

Fueled the german war machine.

Narrator: what's more, morgan Thinks this terror factory

Was built Before world war 2 started,

When this area of poland Is part of germany.

Morgan: the presence Of brick masonry, I think,

Indicates that this is pre-war

Because the deeper You get into the war,

You see brick masonry Disappear in favor

Of rebar reinforced concrete.

[ shouting in german ]

Narrator: during the 1930s,

Germany is forbidden From building

A large war machine Under the versailles treaty

The country signs at the end Of the first world war.

Hitler's solution is to send Scientists into the forests

To secretly develop His sinister arsenal.

Janulis: hitler creates A lot of covert installations

That claim to be For one purpose,

But really have Military applications.

Narrator: studies suggest That between 1933 and 1939,

The fuhrer secretly increases Germany's military spending

By more than 600%.

Morgan: germany had to build

Large industrial manufacturing Facilities like this

In order to wage war in the way That it ultimately would.

Narrator: In the woods of western poland,

The nazis covertly construct A 13.5-square-mile complex.

They use the railway To bring in raw materials,

The steam plant to generate The power needs

For the chemical reactions, The range for testing,

And in the giant silos Visible from space,

They store untold tons Of one of the most powerful

Non-nuclear explosives Known to man.

Janulis: essentially, What we've uncovered here

Is that this is a death factory.

It created the explosives That undoubtedly killed

Hundreds of thousands of people.

Narrator: When world war 2 breaks out

On september 3rd, 1939, This factory helped to fuel

A campaign of destruction

Unequalled in the history Of warfare.

Morgan: rdx goes into the bombs That are dropped on london.

It goes into the v2 rocket.

It goes into artillery shells

That fall on american troops On d-day.

Within two years, a country That was economically destroyed,

Supposedly had no military, Had no infrastructure,

Had basically taken over The entirety of europe.

**

Narrator: when the war ends,

Soviet soldiers Ransacked the facility,

But hitler's death factory Still stands

As a ghostly reminder of a time When millions were unaware

Of the evil About to be unleashed on them.

This is ground zero That opened the door

For the way that germany Would ultimately bring misery

And suffering To the european continent.

**

Narrator: coming up, California's nuclear specter...

Kourounis: Hundreds of thousands of people

Are just going about their lives

Completely unaware To the danger.

Narrator: ...And mad mussolini's Edible paratroopers.

Morgan: we all know The italians love fresh food,

But this is taking it To an extreme.

**

Narrator: november 18th, 2018 --

Passing above the west coast Of america,

Nasa's terra satellite captures This infrared image.

Kourounis: not far from Los angeles, california,

We're seeing a tremendous scar Across the landscape.

Brensberger: it looks like some Of the patches are still green,

But some of it looks Almost like desert.

It's a lot of bare earth,

And given the terrain As well as the pattern,

This really indicates A wildfire burn area.

Narrator: the extent And severity of the scarring

Suggests this was No ordinary forest fire.

Local news reports confirm The satellite has captured

One of the most destructive Blazes in californian history,

The woolsey fire.

This fire is raging Through neighborhoods.

People are trying to escape Any way they can,

Sometimes driving on these roads Through the fire

With flames on either side Of their car.

It must have been Absolutely terrifying.

Narrator: the catastrophic Two-week-long blaze

Forces 295,000 people From their homes.

You would never imagine This happening

In an urban environment.

Narrator: The 100,000-acre inferno

Destroys 1,500 properties And claims 3 lives.

**

It takes two weeks For firefighters

To conquer the blaze.

The people who live here, They want answers.

They want to know How did this fire start,

Where did it start.

Bronwyn agrios Turns to satellite images

Of the catastrophe for clues.

By looking at some imagery

Taken a week before,

We can reveal The current location

Of the fire in bright-red here.

Narrator: by comparing the burn Pattern with prevailing winds,

Agrios pinpoints the first phase Of the fire to a canyon

40 miles north of l.A.

Agrios: we can see the fire Likely started up here

And made its way down south Towards the coast.

Narrator: yet when analysts Study the history

Of human activity In this canyon,

The mystery of the woolsey fire Takes an unexpected turn.

Kourounis: We've got a solid clue as to Where the fire started,

But that's not The end of the story.

Shortly after world war 2,

The u.S. Government tested All kinds of things there

Including experimental Rocket engines.

Narrator: Declassified records reveal That between 1940 and 2000,

The u.S. Government carries out Over 30,000 rocket tests

Near the now Densely populated area.

Albertson: among the projects That were tested out are engines

That were used In the icbm program,

The apollo engine rockets Through the saturn 5 rocket

Were tested here.

Narrator: vast quantities Of various noxious chemicals

Are used in this research.

Albertson: one of the ways They get rid of the materials

Is to burn it, explode it, Or even bury it.

They were doing things Like shooting a rifle

At the barrels of fuel In order to get it to explode.

Narrator: it is believed At least 800,000 gallons

Of toxic rocket-fuel oxidizer And engine solvent

Seep into the ground.

Fanara: These are carcinogenic.

They can cause liver failure.

They are real problems that can Contaminate not only the soil,

But also groundwater

And, eventually, Drinking-water sources.

Narrator: the nightmare scenario Is that the fire has disturbed

And released large reserves of These dormant toxic chemicals.

Brensberger: if this fire is Happening on top of land

That was already toxic,

It's going to cause Catastrophic health for people

That are living there.

[ siren wailing ]

Narrator: yet analysts discover The fire may have unleashed

An even greater threat.

Carter: the most horrifying Aspect of this area

Is where they experimented On nuclear reactors.

Narrator: During the cold-war era,

Scientists at the site Conduct experiments

Using 10 nuclear reactors.

In july 1957, They begin testing a new device

Which uses liquid sodium Rather than water

To cool the uranium core.

Albertson: here we are, We've got a nuclear reactor

Within driving distance Of los angeles

And not a lot of understanding Of how to operate these things.

These are still Relatively new devices.

And this is where It went horribly wrong.

Narrator: during test runs, A leak blocks the cooling system

Causing fuel temperatures To rise to critical levels.

Damaging 13 Of the 43 uranium rods.

This reactor suffered A partial meltdown.

And it's only a few miles away

From where hundreds Of thousands of people

Are just going about their lives

Completely unaware To the danger.

Narrator: the damaged reactor Spits out

Over 450 times more radiation Than that released

During the 1979 meltdown At three mile island.

Yet the extent of the accident

Is kept from the public For decades.

Brensberger: The u.S. Government covered up

What happened with this entire Nuclear meltdown.

This has been one Of the biggest-kept secrets

Of the united states.

Carter: So, you have to wonder --

What is this fire releasing? What chemicals? Radiation?

No one really knows.

Narrator: Government authorities

Are attempting To reassure residents.

The department Of toxic substances control

Says there is no evidence Of toxic spill.

A lot of people are having a Hard time digesting that report.

Carter: we've seen in the past In many instances

Where government officials Have said,

"Oh, the area's fine. The area's clear,"

And upon further investigation, What do we discover?

We have to go back And see what actually happened.

**

Narrator: Coming up, something weird In the deserts of africa...

This looks like The surface of mars.

...And something Even weirder in maryland.

It literally looks like A giant egg.

**

March 16th, 2011.

Eyes in the sky over africa Spot something

In the desert sands Of ethiopia.

This is a very strange image.

You've got the circles of Something colored lightly blue,

And then you've got These bright-red streaks.

Morgan: this looks like The surface of mars.

Who made this, Why did they make it,

And what possible function could These structures be serving?

Narrator: historical images Reveal the mystery structures

Have been here for decades.

This provides military Historians with a clue.

These structures look old.

There's always the possibility

That these might Somehow be associated

With the italian colonial era.

Narrator: italian dictator Benito mussolini

Attempted to build An empire here.

Mussolini has a vision Of establishing

And maintaining an italian Mega colony in africa.

Narrator: analysts learned that This desert contains similar

Circular structures that date From the italian period.

In 1930, mussolini orders Construction of this fort

At the ethiopian desert town Of well well

Near the site in the image.

It's entirely reasonable To assume

That there might Be a connection.

Walters: this is considered A very aggressive act of war,

Effectively, and it drives Ethiopians absolutely crazy.

Narrator: following The construction of the fort,

Ethiopia's emperor, Haile selassie,

Sends a militia to capture it.

Mussolini, in return, Doubles down.

He uses this as a pretext

To try to take over The entire country.

This is classic Dictator behavior.

**

In 1935, 100,000 additional Italian troops

March into ethiopia.

To reach the country's interior, They must cross 120 miles

Of scorching desert sands.

**

Morgan: one of the most Difficult things you can expect

A human being to do

Is to move on foot carrying A heavy load across vast

Distances and godforsaken Waterless terrain.

Narrator: Faced with this death march,

Records reveal the italians Come up with a plan

That could explain The mystery patterns.

**

The italians have this idea That the fighting forces

Would be Resupplied from the air

So that their troops Weren't burdened down

By carrying hundreds of pounds Of individual load out.

The first and possibly Weirdest air-supplied mission

In history begins.

These aren't your typical Meal kits.

They drop everything You would need

To survive out in the desert -- Water, vegetables, utensils --

Oh, and life sheep.

Narrator: to make Fresh lamb and beef dishes,

Mussolini's air crews Attach parachutes

To live sheep and bulls and push Them out of the back of planes.

Morgan: we all know The italians love fresh food,

But this is taking it To an extreme.

It seems utterly nuts,

Taking a sheep, Putting a parachute on it,

And then throwing it Out of a plane.

But what you've got is a Plentiful living supply of food

That doesn't need to be salted Or refrigerated.

[ sheep bleats ]

Morgan: it would make perfect Sense that these were pens

That were hastily built by the Italians to hold the livestock.

Narrator: closer image analysis Appears to confirm the theory.

Nelson: If you zoom in a little closer, It's apparent it's a fence.

These edges are thorny acacias.

Narrator: Yet when ken joyce uses Maxar securewatch technology

To study the lines Next to the pens,

He identifies a problem.

The trails have a very deep-red, Deep-orange color

So, it looks like maybe The top level of soil

Has been cleared.

This is something that is active

And not something that has Just been preserved for decades.

Narrator: joyce dials up The magnification.

So, as I just look close,

I'm starting to see small groups Of white objects,

And each one of these Could well be cattle.

**

One species that's really Adapted to arid environments

Is the longhorn.

Narrator: biologists confirm Herders use these pens or corral

To hold cattle such As the african longhorn.

**

These animals cool Their blood heat

By circulating it Around their horns.

Ones on some breeds Span eight feet.

Schuttler: Cows are really important To the local ethiopians.

They not only depend on them For meat,

But they use their blood To make gravy and bread.

They use the horn and the hides.

Narrator: But it's not just their horns

That make these Animals so weird.

What's really unusual is that Once they get

To their grazing areas, They face in the same direction.

These cattle will often Align themselves north-south.

Narrator: Scientists speculate

These animals have magnetite In their heads.

In effect, this turns them Into living compasses.

Humans don't do this. I mean, some people feel like

They might have A natural sense of direction,

But we can't sense The earth's geomagnetic field.

Narrator: The strange lines in the image

Revealed that the cattle In these pens

Are also creatures of habit.

As the cattle leave And returned to the pens,

They go on the exact same path Every single time.

And that is what is creating These trenches

Down into the red earth.

**

Narrator: coming up, The american military's

Giant egg...

There's something Shrouded in secrecy

Going on beneath that dome.

Narrator: ...And attack Of the robo sharks.

They knew they were biting A human, and they did it anyway.

**

Narrator: november 10th, 2016 --

A satellite Flying above maryland

Spots something strange.

First thing that pops out Is this giant white bubble here

In the middle of the landscape.

Narrator: It looks like a radar,

A golf-ball-type structure

That protects super powerful Radar systems.

But at 200 feet across, it is Far too big and the wrong shape.

It literally looks like A giant egg.

That almost looks like A spaceship has landed.

It even looks like there's A stairway leading up into it.

Narrator: What makes the dome especially Intriguing is its location...

Aberdeen proving ground, Part of edgewood arsenal,

The scene of secret Experiments carried out

On humans, living and dead.

You really have to wonder What kind of tests

Would require a facility Like we see in the image.

Narrator: possible evidence Comes from an fbi raid

On an arizona warehouse In january 2014.

Inside, agents discover Buckets of limbs

And a female head Sewn onto another body

Destined for sale To the u.S. Military.

The fbi files on this Investigation have been sealed,

So there's no real way to know Which bodies ended up

At which military bases

And what kind of tests They were subjected to.

Narrator: human experimentation At the base in the image

Began decades ago.

A lot of work is classified, But some programs

Like operation delirium where U.S. Soldiers were dosed with

Pcp, sarin gas, Just to test the effects,

Those types of drills Were conducted at this location.

Narrator: the authorities claim That experiments on humans

Have now ceased.

Those sorts of programs Are shrouded in secrecy.

So, if there are tests That are being conducted,

It could be hidden Under a dome like this.

Narrator: It is known that research here

Has involved blowing up corpses.

Munoz: the goal of this is To research the effects of ieds,

Including how the body reacts To these types of explosions.

Narrator: this research, According to the military,

Is aimed at saving lives.

Munoz: during the height of the Wars in iraq and afghanistan,

The u.S. Military Really struggled

In how to fortify their vehicles Against roadside bombs

Or improvised explosive devices.

By using cadavers,

The u.S. Army is able To actually see

The effects of an ied On human tissue, human bones,

And funnel them Into training simulations

That could further prevent Injury to u.S. Soldiers.

Can this blast testing Be what's happening

Inside this dome?

**

Narrator: examining the image More closely,

Former cia agent lindsay moran Spots something else.

Not far from this dome,

You can see What looks like a target.

Is that target related To the dome

And to what's going on Under the dome?

Because they're very close In proximity.

Narrator: declassified records Reveal that during the cold war,

This base develops one of the U.S. Military's most powerful

And most outlandish weapons.

Moran: in the early '50s,

The u.S. Military develops The t131,

Which is essentially a weapon

That can fire both nuclear

And also traditional ordnance.

So it's essentially The prototype

Of, like, an atomic cannon.

Narrator: military engineers Based the nuclear weapon

On the anzio annie, A 47-ton motorized gun

Developed by the nazis In world war ii.

Soldiers nicknamed The u.S. Version atomic annie.

Munoz: the bull's eye impression That we see in the image

Could be the target That army researchers used

To test the conventional Shells on this weapon.

**

Narrator: on may 25, 1953,

The military move atomic annie To the nevada desert

To test-fire a live round.

Less than 10 years After hiroshima and nagasaki,

The u.S. Has miniaturized Nuclear technology

To such an extent That we can produce

A 280 mm cannon projectile

With a nuclear warhead.

Narrator: Code name "Grable" shot.

The warhead travels 11,000 yards...

**

...Detonating 524 feet

Above the desert.

Maybe we're developing A new atomic cannon,

And maybe that's why This white dome has been set up.

**

Narrator: according To u.S. Military authorities,

The dome is indeed used For weapons testing,

But not a nuclear gun.

It's used to create specific Outdoor conditions indoors

So that equipment can be tested

Before it goes out into The natural environment.

[ machine-gun fire ]

Things that can be tested In this facility

Range from handheld weapons

All the way up to tanks And helicopters.

Narrator: the dome, it is said, Can simulate conditions

In potential battle zones Anywhere in the world.

Among the conditions that can Be replicated in this facility

Are things like fog and rain,

Conditions that will challenge The effectiveness of equipment

On the modern battlefield.

[ alarms blaring ]

Narrator: mounted into A central control unit,

America's most advanced Futuristic prototype weapons

Are put to the test.

[ gunshot ]

This type of testing Is important

Because you have to understand

How your equipment's Going to respond

In any condition in any place.

Narrator: that, at least, is the Official purpose of the dome.

But this is a secret base, And the precise nature

Of the experimental work here Remains classified.

Moran: This is one of those situations

Where, looking at the image,

You know there's something Shrouded in secrecy

Going on beneath that dome.

**

Narrator: coming up, Rise of the shark mega-swarms.

Unprovoked attacks Are increasing.

So it makes you wonder why.

Narrator: january 21, 2017.

Eyes in the sky

Track the 170-mile mediterranean Coastline of israel.

All seems normal,

Until 30 miles north Of tel aviv,

This happens.

**

Wow. There are A lot of sharks here.

There are so many congregated Here in one spot.

This is really amazing.

Narrator: image analysis Suggests the mega-swarm

Is made up of many Different species of shark.

The aerial images Baffle biologists.

This is extremely unusual.

Most of the time, You'd see one or two sharks

Swimming around.

Sharks generally are solitary.

They don't tend to congregate.

When you do see A bunch come together,

You have to wonder what's Attracting them to this site.

Narrator: analysts consider If the swarm is connected

To a spate of shark attacks In the region in recent years.

At an egyptian resort, Four people were attacked

In just minutes of one another.

And a few days later, A german tourist was killed.

**

Nelson: Shark attacks are very unusual.

So if you have a bunch of them

Happening at the same time In the same location,

It makes you think, "What is happening here?"

**

Narrator: The sharks in these waters

Appear to have deliberately Targeted humans.

All the attacks Were in clear water.

So the sharks weren't really

Mistaking people For something else.

They knew they were Biting a human,

And they did it anyway.

**

Narrator: in the aftermath Of the attacks,

An egyptian government official

Makes a startling statement.

Allegedly, a trained diver Caught one of the sharks

And discovered a device on it.

Narrator: the official claims The device was manufactured

By the israeli Intelligence service.

The suggestion is that

Maybe these sharks Are somehow remote-controlled.

Narrator: this isn't the first Time people in the region

Claim to have found animals With devices attached to them.

Various suspect animals Keep appearing.

For example, hezbollah Captured a kestrel.

And in saudi arabia, They found a vulture

That had some kind Of device on them.

**

Narrator: it is known That intelligence agencies

Have been attempting to Weaponize animals for some time.

In a 1972 u.S. Program Code-named paisley print task I,

Remote-controlled monkeys Are used for reconnaissance

And sabotage missions.

Man: the subject was deemed ready to penetrate hostile areas

and seek out and destroy selected targets

within those areas.

mission complete.

**

Narrator: and israel has One of the most advanced

And successful intelligence Agencies in the world.

Mossad certainly has used Atypical means in the past

To get at their enemies.

Narrator: mossad denies Any experiments using sharks.

Moran: the israeli officials, When confronted

With these accusations, Outright deny them

And, in fact, said That the egyptian official

Must have seen "Jaws" Just one too many times.

Narrator: investigators consider What else could be drawing

Unusually large numbers of Predators to this area of ocean.

The wider satellite image Offers another clue.

This image is just off The coast of hadera in israel,

And there's a power plant Right on the edge of the water.

**

They use water To cool the station,

And then they dump the hot water Back into the ocean.

That actually raises The temperature

Of the ocean around it.

Schuttler: Sharks are cold-blooded animals,

So maybe these sharks Are coming to the warm waters

From the power station.

And warm water Can stimulate their metabolism.

Narrator: but there are many Such power plants in the world,

And they don't attract Swarms of sharks.

Scientists are still studying This phenomenon

About why exactly These sharks are coming here.

Narrator: Since the footage was taken,

More shark mega-swarms

Have mysteriously Started to appear

In different parts of the world.

Among them are huge numbers Of great white sharks

Just off the coast of america.

Chamberlain: Sharks are showing up

In places That they have never been.

And no one is really quite Certain why this is happening.

Worldwide, the number Of shark attacks

That are happening Is also increasing.

We know worldwide, sharks Are decreasing rapidly.

We're fishing a lot of sharks,

Yet unprovoked attacks Are increasing.

So it makes you wonder why.
