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?

Naked Science: Swallowed By The Sun

The sun ages rapidly and the world struggles to survive. Swallowed by the Sun is a story of what would happen to planet earth if the sun rapidly turned into a red giant. The Sun will run out its power all in 6 to 7 billions from now. At that moment, it will expand to an red giant. And the Earth, its planet, will burn in the heat from the Sun.

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.

What are the most violent and dangerous planets in our Solar System?

One day the time may come when humans have developed technology advanced enough to send sections of Earth’s population to settle on other planets. What kinds of world can we expect to find, how do they compare with our own, and what measures would we need to take to adapt to their alien environments? Naked Science takes us on journey through the Solar System and beyond, examining some of the most extreme characteristics of our planetary neighbours.

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.

The Real Star Trek discovers the challenges humankind will have to overcome to journey to distant stars.

One day we may face no choice but to leave Earth, forced by an ice age, pollution or a meteorite to find a new home elsewhere in the galaxy. The difficulties are daunting, humans evolved to live on Earth, not in space. We meet the scientists who are making journeys to Mars and beyond possible.

The first task is finding the right planet; humans need oxygen and water, so not any old planet will do. We meet David Miller, the MIT scientist who works on the Terrestrial Planet Finder project and thinks it will make the job of finding a new home a whole lot easier. The ‘TPF’ is a set of orbiting satellites which are able to spot Earth like planets and reveal whether they have a ‘human-friendly’ atmosphere.

Once we’ve found a target there’s the small matter of getting there. Just travelling to Mars and back is likely to take years. Journeys to stars are likely to be decades if not centuries. We look at some of the concepts to come out of NASA’s propulsion labs, from solar sails to antimatter.

But even the rocket scientists can’t make our ship break the speed of light; we have to accept that crews are going to have to be in this for the long haul. We meet scientists who are trying to ensure that they arrive at their destinations healthy and ready to start life on a new planet.

At MIT we see centrifuges that mimic the effects of gravity, installed in a spaceship they might stop the crippling loss of muscle and bone mass that would threaten our astronauts. Dava Newman demonstrates her revolutionary design for a spacesuit on a climbing wall, made of flexible material it will work with the wearer unlike the bulky suits currently used. We also reveal the work being done to overcome the deadly effects of cosmic radiation that threatens to wreck our crew’s DNA.

We also look at the work being done to keep our crew in sound mind. Sealed in a ship for years with only faint communications with Earth they may rely on the software being designed by David Dinges, which allows a computer to spot when humans are becoming stressed.

Eventually though we may have to accept that more drastic changes are needed before we can leave for the stars. From hibernation pods, to methods to slow down aging, the world of science fiction may have to become fact before we can leave our solar system. And if we embrace genetic manipulation to redesign ourselves for space we may also have to change our ideas of what a human is.

Harbingers of doom or givers of life?

Comets, distant travellers from the outer reaches of our solar system, have captured the imagination of man and have long been shrouded in mystery. Now through Earth based observations and an increasing number of space probes, their origins and nature are becoming unveiled. Naked Science explores behind the legend to reveal what a comet actually is, what secrets they hold for our understanding of how the solar system was formed; shed light on the theory that they brought the building blocks of life to earth and their potential for wiping out life as we know it.

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.

Universe: Beyond the Millennium - Stars

Universe: Beyond the Millennium is a television series observing astronomical phenomena, research, and theories on the universe and its origins.

Narrated by John Hurt.

The documentary premiered in 1999 and presents an overview of the universe as humans understood it at that time, and how we think it will evolve in the next millennium. Using 3D computer generated graphics, the series features animated sequences that offer insight into the Big Bang theory and the anatomy of the sun.

Stars, scientific studies of our sun and surrounding stars are revealing discoveries that link electric and magnetic weather patterns of the sun with storms that rage on the earth. Similarly, viewers learn how the sun's electro-magnetic properties can close the Toronto Stock Exchange and turn off all the lights in New York City.

In five billion years, our nearest start, the sun, will die, swelling and becoming a red giant. The heat will be so intense the oceans will boil. Our planet will be scorched beyond recognition. The crust will melt, the surface will become an ocean of molten rock, all life will end, in the ultimate armageddon.

Ageing - Death is Life

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

Ageing, or aging, is the process of becoming older, and one of the great mysteries of life.

Death, like life, is an amazing biological process engineered into cells of the body. Just as our DNA dictates the timeline of our development it also puts a cap on how long we can live.

Why does our appearance change so very much between the ages of 40 and 70. It’s more than wear and tear, it’s a process affecting every cell in our body. Every day cells clone themselves in their billions, the DNA inside is also copied, as old cells die off, the new ones take their place. The trouble is that this cloning system isn’t perfect, any imperfections in the DNA are also replicated. In a lifetime we make so many copies of our cells that even the tiniest errors accumulate with time, imperfection is exaggerated until cells eventually lose the ability to divide altogether.

Clip from the critically acclaimed documentary “The Living Body”.

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?
