Every other Wednesday we present a new video, so join us to see the truth laid bare...

How did the Earth evolve to support life.

Our planet now supports a huge diversity of living creatures requiring very special conditions, but what was the series of events that brought this unique set of conditions together? What did it take to make a world that would support human life? Naked Science takes an imaginary ‘human’ time traveller on a journey back to the moment of formation of our solar system. We meet the scientists who are carrying out their own detective work, uncovering the clues around the world today into what our planet was like 4 and a half billion years ago.

Our journey begins with the astonishing story of how a giant cloud of interstellar dust and gas collapsed to form the sun and planets. We discover that the intense heat of the early Earth created a molten iron core. This generated a magnetic shield around our planet that protects us, to this day, from the sun’s deadliest particles.

Many of the features we take for granted on our living planet were forged in the most violent event in our planet’s history. Early in its life, the Earth collided with another planet. Planetary Scientist Robin Canup has modelled the impact using supercomputers. She reveals that the resulting fireball was so energetic it melted the Earth and created the moon. This dramatic impact gave us our tides and seasons.

We wouldn’t have life today without water. But where our water came from is a mystery that has long puzzled scientists. At a NASA research laboratory, Michael Zolensky studies a recently discovered meteorite that supports the view that water came from space.

For the first half of its history the Earth had an atmosphere of methane and carbon dioxide we would find impossible to breathe. One clue as to how the earth acquired its oxygen can be found in Australia. Shark Bay in Western Australia is home to strange bacterial mounds called stromatolites. The bacteria in these objects are pumping out oxygen. A few hundred miles away geologist Martin Van Kranendonk shows us a fossil stromatolite, the world’s oldest fossil. The evidence suggests that these strange objects are responsible for creating the air we breathe.

Where does a cup of coffee come from? In this film, it’s not Starbucks, it’s stars busting. We go right back to the beginning of time to show where the ingredients in your cup of coffee were born.

The main ingredient is hydrogen; it makes up most of the water in your cup. And that formed in the big bang. How it got from there, into your cappuccino is one of the most dramatic stories in science. It has taken thousands of scientists to track its trail. We follow it through stars and galaxies, exploding supernovae, and giant clouds of gas to show just how it reached your cup.

But that isn’t the end of the story. For where it goes in the future, depends on the fate of the universe. Will it carry on expanding for ever, or tear itself apart?

The History of Earth - How Our Planet Formed - Full Documentary HD

In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.

It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in - when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock - a magma ocean.

Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age.

When Did Life on Earth Begin?

Scientists are still trying to unravel one of the greatest mysteries of earth: When did life first appear and how did it happen? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.

Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of living time. Perhaps we've been getting periodically belted by more space rocks (ie. asteroids), or the collision of neutron stars happening too close for comfort? Each time a mass extinction occurred, life found a way to come back from the brink. Life has tenaciously clung to this small blue planet for the last three billion years. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.

Every other Wednesday we present a new video, so join us to see the truth laid bare...

There is a place on Earth that we have never seen. It is a place of unimaginable heat and pressure, where no life could survive. Yet without it, we would perish for it holds the key to our precarious existence on this planet.

2000 miles below the Earth's surface, there is a vast ocean of molten iron. The spinning outer core of the Earth generates a protective magnetic shield around the planet, defending life from lethal space radiation. But now there is startling data that it could be about to stop defending us. Naked Science is taking you on a journey to the centre of the Earth.

Every other Wednesday we present a new video, so join us to see the truth laid bare...

The moon is far more than just a beautiful object in the night sky.

Ever since its creation 4.5 billion years ago the moon has been edging away from Earth into space. Throughout its journey, it has influenced our planet in different ways. But one things clear, without it life would never have emerged on Earth.

4.5 billion years ago the moon forms when another planet slams into the early Earth. The impact knocks our planet “off-balance” onto an axis of 23 degrees, which we still rotate around today. This is what gives us our seasons. Without it we would have no summers, springs, winters or falls.

4 billion years ago the solar system endures the most violent meteorite bombardment in its history, the Lunar Cataclysm. The Earth, being 50 times bigger than the moon, exerts a massive gravitational pull on incoming space debris. Because the moon is still so close to Earth it too gets hit. 99% of all craters on the lunar surface visible today are a result of this bombardment.

3 billion years ago the Earth has water and oceans. Because the moon is far closer its gravitational pull is far stronger on the Earth. The tides it creates are thousands of feet high and smash hundreds of miles inland every day. Scientists believe that these tides feed the Primordial Soup with the minerals required to start life. Without them only the most basic microbes would be on Earth today.

Today the moon has the same gravitational pull as a mosquito landing on your head, yet some people still believe it can influence our planet in bizarre ways.

The San Francisco Police Department tell us how crime appears to soar during a full moon. But the scientific data suggests otherwise, studies show no correlation between the Full Moon and violence. Naked Science investigates.

Scientific research into the moon is allowing some scientists to predict when natural disasters will strike. Some researchers believe that when the sun and moon align and pull together on the Earth they can trigger both earthquakes and volcanic eruptions.

In the future the moon will move so far from Earth that it will affect the fine balance of our planet, sending our climate tumbling out of control.

Catastrophe - Episode 2 - Snowball Earth

Subscribe to Naked Science -

Every other Wednesday we present a new video, so join us to see the truth laid bare...

This spectacular five-part documentary series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe.

99% of all the creatures that have ever lived, no longer exist. They were wiped-out in a series of global catastrophes. Each disaster changed the course of evolution on earth. Without them mankind, nor any of the life we see around us, would be here today. For out of catastrophe comes rebirth. Evolution is a savage, imperfect and violent process. It's survive or perish. The earth's history of catastrophes has both moulded the planet and determined evolution. For each disaster led to another leap forward on the evolutionary trail form single celled bacteria to humankind itself.

Episode 2 - Snowball Earth

This programme delves into a world lying beneath a frozen surface. It is the greatest climate disaster ever to have hit Earth. 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.

Snowball Earth uncovers the story behind one of the most controversial theories in science today. To investigate, the programme travels the world to follow scientists scouring southern Australia, Nevada's Death Valley and Alaskan glaciers for tantalising clues as to how our planet ran away into this doomsday scenario. The results could improve understanding of evolution and survival of life.

Birth of The Solar System

Where did our solar system come from? The advent of space flight and space-based telescopes gave us unexpected clues to how our solar system began.

Naked Science - Colliding Continents

Subscribe to Naked Science -

How were the continents formed?

We walk over them without a second thought, but where did the land beneath our feet come from? We go back in time to the oldest rocks on earth, to see how the first continents formed on our fledgling planet. We see how continents are just lighter rocks, floating on a layer of denser molten rock, the mantle.

Travelling to the bottom of the Grand Canyon we follow the process of erosion and sedimentation that created the landscape we see today. At the Giant’s Causeway, in Ireland, we tell the story of how a continent split into two, creating America and Europe, and in the Himalayas, we see how two continents colliding create the tallest mountains on earth.

But what of the future? Using computer simulations, we trace the progress of the continents over the next 250 million years and discover that they will all merge into one.

Naked Science - Death of the Sun

Subscribe to Naked Science -

The Sun is the most powerful force in our solar system. It generates the heat and light that sustains us. Without it we wouldn’t have life on Earth. But the Sun is violent and volatile and is becoming more dangerous as it ages.

Naked Science explores the life and death of the Sun. We explore what will happen in the future as the Sun ages, and how our lives linked to the Sun’s life cycle.

Firstly we want to understand how the Sun was created from a giant cloud of dust and gas. Scientists pretty much agree on the theory but physical evidence is hard to come by. Naked Science meets scientists at Johnson Space Center who have been working on a ten year mission to bring a piece of the Sun back to Earth. How do scientists collect samples of the Sun when a probe could never get near the Sun’s surface? We follow NASA’s dare devil mission to capture the samples.

Today we rely on the Sun to live. It’s energy fuels trees and plants which are essential for the food chain we all depend upon. But how do we get the energy? Naked Science explores the incredible journey that the particles of light from the Sun have to make to earth to deliver their energy.

How old is the Sun? This is a question which has fascinated scientists for a long time. Scientists have now established the Sun’s age with the aid of one remarkable fact that the Sun sings. We visit Big Bear Solar Observatory in California to meet one of the scientists who has been at the forefront of using the Sun’s sounds to determine its age.

The Sun’s warmth and light helped life on Earth to begin but it can also play havoc with our modern way of life. Billions of tons of plasma erupting from the sun send powerful storms hurtling through our solar system. We visit the Space Environment Center in Boulder, Colorado where they try to predict the sun’s violent moods. 1989 brought one of the most dramatic space storms and Naked Science uncovers the events which took place on the Earth. But what lies behind the explosive events on the Sun. We travel to the California Institute of Technology in Los Angeles where they are trying to understand the science behind the explosions by creating them in the laboratory.

But what about the risks of solar storms to astronauts in Space? Naked Science meets Michael Foale who was directly in the line of fire on the International Space Station during the intense solar activity in 2003. There is one solar event astronauts can’t be protected from. A superflare. Superflares are up to 10 million times more energetic than the most powerful solar flares. Naked Science journeys to Louisiana to meet an astrophysicist who has found evidence of nine stars that have experienced superflares. What if our sun ever produced a superflare, what would happen to life on earth?

We know when the sun was born, how it nurtured us and how it has thrown a fair amount of danger our way. But how and when will it die and will the Earth survive?
