Hey Thoughty2 here, nature often presents us with some rather uncanny and unexplainable

events.

Here are some of the strangest natural occurrences of all time.

Angel hair is a rare phenomenon where extremely fine silken threads fall from the sky, it

has been described as similar to cobwebs.

However it is extremely delicate and appears to completely vanish when you touch it.

The phenomenon has been witnessed most often in North America, Australia, New Zealand and

Western Europe.

There is no known evidence that tells us where this strange substance comes from or what

it's made up of.

The material's extreme sensitivity makes it almost impossible to collect and analyse.

Many believe it is linked to UFO sightings as many have reported seeing angel hair at

suspected UFO crash locations.

There have also been reports of angel hair sightings at the Miracle of the Sun in Fatima.

In June 1908 a ball of fire exploded in a remote area of Russia.

It caused localised earthquakes and instantly flattened 80 million trees over an area of

830 square miles.

An explosion of such magnitude would have been capable of wiping out an entire city,

however because the area is so remote there were no fatalities.

It is now known as the Tunguska event because of it's close proximity to the Tunguska river.

The blast reached 15 megatons of energy, that's a thousand times more powerful than the Hiroshima

Bomb.

Research suggests the explosion was caused by an asteroid impact, because a nearby lake

is believed to have been created by the impact.

However other researchers say the lake was there before the event.

Over 1,000 scholarly papers have been published on the event, however we still don't know

for certain what happened that day.

If you think fire balls are weird, how about intelligent balls of lightning?

Ball lightning as it's known is a seemingly paranormal phenomena where a sphere of lightning

appears and flies around in an autonomous fashion.

Ball lightning has a life span of less than five seconds, it can appear randomly at any

location during a thunderstorm.

However the creepiest thing about ball lightning is that it acts as though it has intelligence

of its own.

It usually enters buildings through a window or door, it avoids colliding with objects

and navigates itself through hallways.

Also witnesses say ball lightning can pass through walls however sometimes it leaves

a hole in the wall and other times it passes through without leaving a trace.

As if it can do what it wants.

One of the first documented sightings of ball lighting was in January 1984, according to

eye witnesses ball lightning approximately 4 inches in diameter entered a Russian passenger

aircraft, flew above the heads of the passengers, then once it reached the tail section, split

into two glowing crescents then joined together again and exited the plane.

It left two holes in the walls of the plane.

Because this natural phenomenon is so rare there is currently no generally accepted theory

for ball lightning, and it has baffled scientists for centuries.

In 2,000 in Ethiopia fish fell from the sky, yes that's right.

A local newspaper reported: "The unusual rain of fish, which dropped in millions from the

air - some dead and others still struggling - created panic amongst the mostly religious

farmers.".

But this is not the only account of raining animals, far from it.

In fact almost every year since records began there have been reports all around the world

of animals miraculously raining down from the sky, in some cases hundreds of miles from

the nearest body of water.

But it's not just fish, people have also reported raining frogs, snakes and even alligators.

Science says the most likely explanation for this phenomena is a type of tornado called

a waterspout which forms above water.

A waterspout has enough sucking power to suck up masses of water as well as any animals

it contains.

Once the animals have been sucked into the upper atmosphere they can be carried by winds

hundreds of miles until they eventually fall back to earth as rain.

In the summer of 1997 an ultra-low frequency sound was detected underwater by the US National

Oceanic and Atmospheric Administration.

It sounded like this.

The sound was affectionately named "The Bloop".

The Bloop was so loud it was picked up on multiple sensors over 5,000 kilometres apart.

According to scientists who have studied the Bloop, it matches the audio profile of a living

creature, however there is no known animal that could have produced a sound of such amplitude.

If it did come from an animal it would have to be several times the size of a blue whale.

Which led to speculations all over the internet of a giant underwater sea monster.

However, after many years of scientists being baffled by the Bloop, NOAA recently discovered

the noise was caused by an ice quake in Antarctica, which is when an ice shelf cracks.

An estimated 2 to 10% of the world's population are plagued by a relentless, mysterious humming

sound of un-known origin.

This unexplainable phenomena is known as "The Hum".

Scientists have investigated the hum multiple times, however in places where the hum has

reportedly been heard, scientists could never locate the source of the sound.

Which makes investigating this peculiar phenomenon rather difficult.

According to sufferers of the hum it sounds similar to a diesel engine truck idling outside

their house.

But what's even weirder about this strange sound is that it isn't present everywhere,

it can only be heard in certain places.

Notable places the Hum has been heard in include Taos, New Mexico, Bristol, England and Largs

in Scotland.

But the hum is constantly appearing in new towns and cities across the world, it has

become such a global problem that a website was started that keeps track of every location

the hum has been heard around the world.

Perhaps one of the weirdest natural phenomena of all are Rods.

Rods were discovered accidentally in March of 1994 by filmmaker Jose Escamilla.

Rods are peculiar flying entities that can only be seen on slowed down videotape and

sometimes in still photographs.

Rods are cylindrical shaped objects that travel too fast to be seen by the naked eye and move

through the air like a fish moves through the sea.

Because of the speed they travel they have never been studied by science but there are

many theories as to what rods really are.

Some believe they are secret high tech missiles being tested by the government, because they

appear to travel in a absolute straight line.

Others theorise that they are entities from another dimension, briefly passing through

our dimension in a split second.

Or the could simply be another species of insect still unknown to science.
