    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.

    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.

    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.

  • Iridium and the Dinosaurs

    The iridium anomaly. 550 metres beneath the Earth's surface there exists a thin layer of space rock. Often taken as evidence of an extraterrestrial impact event resulting in the extinction of the dinosaurs, along with about 70% of all other species.

    Footage from the 2012 documentary, Down to the Earth's Core.

    We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself.

    It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination.

    Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds.

    As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe.

    Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

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

    For over four and a half thousand years the pyramids of Egypt have stood as wonders of the world. The facts are astonishing, the Great Pyramid alone weighs almost six million tons and contains over 2.3 million stone blocks. Naked Science sets out to uncover four great mysteries that still surround the pyramids, how were they built, who built them, why were they built, and what secrets may still lie hidden within their stones. As four millennia and countless generations stand between us and the men who built the pyramids we have to study the buildings themselves to uncover the answers.

    With British engineer Denys Stocks we learn the art of pyramid building. Stocks has spent twenty years mastering the techniques used by the ancient workmen and shows how such vast quantities of stone were quarried, transported and fitted by a civilisation that had not even invented the wheel. To show the scale of the achievement we asked construction manager and pyramid scholar Craig Smith to calculate what it would take to build a pyramid in today’s money.

    We may know the names of the pharaohs who commissioned the pyramids but who actually hauled the blocks. Legends have always held that slaves built the pyramids but we venture into the science of Forensic Egyptology to discover the truth. Mark Lehner discovered the town of the pyramid builders while Zahi Hawass takes us on a tour of their tombs.

    There may be few records of how the pyramids were built but hieroglyphic texts within some pyramids hint at their reveal purpose. Salima Ikram and Jim Allen help us find for the reason why the pyramids were built within these spells and incantations. However Robert Bauval, believes there may be deep connections between the pyramids and astronomy. He believes links to the stars are hidden within their stones and chambers.

    Finally we follow work in pyramid exploration as teams hunt for hidden chambers and use robots to explore the mysterious shafts at the centre of the Great Pyramid of Giza.

    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.

    Just for a moment, imagine a universe awash with life, where we humans are not the only intelligent beings around. What might these alien races look like? Could we communicate with them, or even recognise them as intelligent? And what would they make of our violent and dangerous species? Might they take one look, and decide not to bother with such primitive beings? A planetary nursery filled with spiteful, galactic infants. On the other hand, in our imaginary scenario, they may enrich us with scientific knowledge beyond our imagination. Or could an encounter with aliens have a more destructive outcome? It could be a bad day for human kind. But relax, it’s just make believe, it could never happen, could it?

    A mysterious crash in Roswell, New Mexico during the 1940s convinced many that our planet is being visited by space aliens. Crop circles in Britain have only added fuel to the fire. Few scientists doubt that life indeed exists elsewhere, but some believe we're more likely to make contact via radio waves. Join the search for extra-terrestrials and hear from scientists who think we are on the verge of making contact.

  • Naked Science - Loch Ness

    50:05

    Subscribe to Naked Science -

    Naked Science investigates the truth behind the legend.

    The legend of the Loch Ness monster dates back 1500 years. Since then, 1000 eye witnesses, countless photographs, sonar records and films have testified to the existence of a Loch Ness monster. Yet despite extensive exploration, observation and scientific analysis, still no real evidence has been discovered.

    This documentary starts off charting the early history of the legend. From the first sighting by St Columba in 565AD, to the ‘Spicer’ sighting that kicked off the modern legend in 1933 and the world famous ‘Surgeon’s Photo’ from 1934 that captured what appeared to be a head and neck emerging from Loch Ness. From the ‘Surgeon’s Photo’, the press, frenzied public and scientific observers soon concluded that the creature living in the loch was a long-extinct dinosaur called a plesiosaur. A preposterous suggestion it would seem. However Naked Science profiles the coelacanth. A fish thought to be extinct 80 million years ago but discovered in 1938, to much surprise, living off the coast of Madagascar.

    But even if it was a dinosaur from the Triassic period, how on earth did it get into the loch? Loch Ness was gouged into today’s U shape valley by a series of glaciers that last melted 11,000 years ago, long after the extinction of the dinosaurs. Naked Science profiles the geology of the loch and examines whether the sea has ever intruded into the loch perhaps carrying an unknown creature in with it.

    After decades of intense observation of the surface of the loch by volunteer monster-hunters from around the world, in the late 60s Adrian Shine, skeptic, naturalist and leader of the Loch Ness Project arrived on the scene. He took a different tactic. Rather than search for a big monster, he looked for creatures just 100th of an inch in diameter, zooplankton. A monster brood hiding out in the loch would need plenty of zooplankton, to support plenty of fish, who in turn could support large creatures. Naked Science examines this ecology for clues. We also discover there are internal waves called seiches, mirages, local wildlife, large fish such as sturgeon, floating logs, boat wakes and strong winds that could all have their place in provoking monster sightings.

    But what of all the photographic evidence? The most famous moving image of the Loch Ness monster is the so-called Dinsdale film of 1960. At the time Britain’s foremost photographic analysis experts concluded it was an animate creature. Using high spec imagery analysis we show how the famous Dinsdale film was most probably a helmsman in a boat. Likewise we demonstrate that the McNab photo of 1955 could also be a boat wake. Naked Science reveals that the notorious ‘Surgeon’s Photo’ was actually a hoax. We show how in 1933 big game-hunter Marmaduke Wetherell planted some footprints on the loch side and passed them off as the monster. Humiliated when his first hoax was discovered, Wetherell’s revenge was the ‘Surgeon’s Photo’. In a reconstruction, we show how easy it was for him to fabricate a monster from a toy submarine and reveal how the hoax remained a secret for 50 years. Finally we look at the most unique theory by Italian geologist Dr Piccardi, that earth tremors along the Great Glen fault provoke water disturbance that are mistaken for monsters thrashing around in the water.

    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 3 - Planet of Fire

    250 million years ago, 95% of life was wiped off the face of Earth in the biggest extinction event ever. But what was responsible? Back then, our planet was a very different place. Millions of years before the era of dinosaurs, creatures such as Dicynodonts and Gorgonopsians roamed the land, while the oceans too teemed with life. Then, in the blink of a geological eye, everything changed. Life itself was almost completely wiped out in what is known as the Permian extinction. Travelling to locations such as South Africa, California, and Iceland, the experts discover that the volcanic activity of the Siberian Traps led to the release of deadly gases from beneath the sea and rises in Earth's temperature. This turbocharged global warming brought drought and a breakdown in the food cycle, with even the strongest animals eventually succumbing to the conditions.

    Will the magnetic field of the Earth reverse its direction in the future? Will this cause problems?

    The magnetic field of the Earth has actually switched its direction many many times during Earth's history. Although this is not completely understood, the leading theory of how it works is that Earth's magnetic field is caused by the motion of the liquid outer core. The churning of the liquid in the outer core acts as a giant electromagnet, moving electrical charges around, in what is known as the 'geomagnetic dynamo.'

    What If Earth's Magnetic Poles Flip?

    The end of the world as we know it could come in any number of ways, depending on who you ask. Some people believe global cataclysm will occur when Earth's magnetic poles reverse.

    Oxygen - we all need it, we can't live without it. It's integral to life on this planet. And it's probable that, as you watch this film, you will be breathing in an oxygen atom that was also breathed by Genghis Khan - or by the first ever apes to stand upright on the plains of Africa.
    The oxygen that we breathe is made from two oxygen atoms joined together - O2. They were first joined more than 3 billion years ago by the earliest blue-green algae to evolve.
    The oxygen molecule first came from bacteria and was present in the fires that destroyed the dinosaurs and the chemical reactions in all human cells, and as ozone they protect the earth from radiation.
    Since then, both together and apart, they've had the most extraordinary adventures. Each of the two atoms in an oxygen molecule is virtually indestructible - so they have been first-hand players in some of the most dramatic events in the whole of Earth's history.
    It's often said that we are breathing the same oxygen that the cavemen did. The life of a single molecule of oxygen is traced on it's astonishing journey spanning millions of years, from its creation, into photosynthesis, through the age of the dinosaurs, early man, and on into today.

    Machines are evolving 10 million times faster than we are. Are you ready for robots that run our homes, watch our neighborhoods and even fight our wars? One day in the not too distant future, robots will travel to the far reaches of the universe, they will be the first to colonise new worlds. Robots will lead the way in the exploration of deep space.

    Robots, machines of our nightmares, or servants of man? In the 1930s film Metropolis the robot was an evil character, it represented our darkest fears. By the 1950s they had become even more sinister and powerful, but over that last few decades our opinions of robots have dramatically changed, they’ve been reinvented as the police force of the future. But can real robots match the exploits of their celluloid cousins?

    While the movies were creating ruthless men of steel, real robots were starting their own painful march into the world. Robots are still basic but over the past few decades they have advanced enormously. Before robots can become the masters of the universe, or even the servants of mankind, they need to accomplish one important thing, they need to move around.

    This 1999 documentary includes interviews with prominent roboticists and artificial intelligence specialists. Beginning with robot locomotion and historical clips of ingenious experiments from MIT's Leg Laboratory, BigDog's ancestors dynamically walk, hop, trot, and perform impressive gymnastics. To find out the best way for a robot to move around the scientists look to nature. There have been many attempts to copy nature, some successful, others less than perfect.

    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.

  • Worlds Deepest Mine - Gold Alchemy

    4:51

    South Africa's TauTona mine, real life alchemy, and Halicephalobus Mephisto. Footage from the 2012 documentary, Down to the Earth's Core.

    We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself.

    It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination.

    Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds.

    As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe.

    Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

  • Naked Science - Lightning

    Six times hotter than the surface of the sun, lightning is one of the world’s strangest phenomena. This film follows the progress of a lightning stroke, from its birth in the clouds, to the weird sounds called whistlers that follow it.

    In Australia we follow lightning researchers flying into storm clouds, to discover what triggers a lightning stroke. At the International Lightning Center in Florida we find new research that suggests that cosmic rays from outer space trigger lightning. We meet a golfer struck by lightning, and reveal what happens when you’re hit. Why do some people survive, when others don’t?

    One of the weirdest forms of lightning is ball lightning, but is it real, or a myth? We talk to people who have seen it. And we see stunning footage of sprites and other forms of lightning that go up from clouds towards space, and see them recreated in a laboratory. The film climaxes with the discovery that without lightning, we wouldn’t have satellite communication. Our modern way of life would be impossible.

    Journey to the Edge of the Universe

    Using cutting edge visual effects and CGI - we create the first accurate non-stop journey from here to infinity. In one single, epic camera move we travel from two people staring at the night sky, accelerate up and out of our atmosphere, past the aurorae, past the Moon and our neighbour planets, out of our Solar System, to the nearest stars, nebulae and galaxies and beyond - right to the edge of the Universe itself. On this awe-inspiring and unique voyage we encounter the most beautiful, powerful and mysterious phenomena in the Cosmos, from pulsars to supermassive black holes, from star nurseries to quasars. Ultimately, we take the audience to the very edge of Time itself in a scientific and visual HD extravaganza that maps the Universe itself and will be the most stunning cosmology film ever made.

  • The New Zodiac - Astrology vs Astronomy

    23:43

    It's 5:07pm on the 10th February, and a child is being born in central London. According to astrology he's born under the star sign Aquarius, he will be innovative, sociable, and unconventional. But we can reveal that the method that Western astrologers use to calculate our star signs is flawed. This programme will show that we are all reading the wrong star signs, we unveil the truth about astrology and The New Zodiac.

    For centuries astrologers have believed that we are all intimately linked with the heavens, the exact position of the planets and stars act as a celestial mirror which reflects our personality, and our destiny. Astrologers base their predictions on the movements of the sun, the moon, and the planets as seen from Earth. As they move these heavenly bodies cross in front of 12 groups of stars called constellations. The ancient Greeks thought that these constellations look like figures, a crab, some twins, even a bull. This journey through the 12 constellations inspired astrologers to divide the sky into 12 equal segments, each representing a month. We know these constellations as the 12 signs of the zodiac.

    This 2001 documentary was produced by Pioneer Productions for Channel 5.

    Featuring contributions from astrologers Russell Grant and Roy Gillett, interviews with astronomer Dr Francisco Diego (University College London), psychologist Dr Chris French (Goldsmiths College), and media sceptic Tony Youens.

  • Gaia Hypothesis - James Lovelock

    28:47

    James Ephraim Lovelock, is an independent scientist, environmentalist and futurist who lives in Dorset, England. He is best known for proposing the Gaia hypothesis, which he discusses in this exclusive interview, filmed in 2007.

    The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. Topics of interest include how the biosphere and the evolution of life forms affect the stability of global temperature, ocean salinity, oxygen in the atmosphere and other environmental variables that affect the habitability of Earth.

    The hypothesis, which is named after the Greek goddess Gaia, was formulated by the scientist James Lovelock and co-developed by the microbiologist Lynn Margulis in the 1970s. The hypothesis was initially criticised for being teleological and contradicting principles of natural selection, but later refinements resulted in ideas framed by the Gaia Hypothesis being used in fields such as Earth system science, biogeochemistry, systems ecology, and the emerging subject of geophysiology. Nevertheless, the Gaia hypothesis continues to attract criticism, and today many scientists consider it to be only weakly supported by, or at odds with, the available evidence. In 2006, the Geological Society of London awarded Lovelock the Wollaston Medal largely for his work on the Gaia theory.

    Can we realistically reduce carbon dioxide emissions?
    Have we passed the tipping point?
    Could Earth become as lifeless as Mars of Venus?
    Is there any hope for the human race?

    Concorde is the greatest civilian aircraft ever built. In the aviation hall of fame Concorde stands second only to the Wright brothers' maiden flight. Even before she leaves the ground, she goes like a bat out of hell! She cruises at twice the speed of sound, faster than the earth rotates. She's so far ahead of the pack, she's out of sight!

    Aérospatiale-BAC Concorde is a retired turbojet-powered supersonic passenger airliner or supersonic transport (SST). Concorde was jointly developed and produced by Aérospatiale and the British Aircraft Corporation (BAC) under an Anglo-French treaty. First flown in 1969, Concorde entered service in 1976 and continued commercial flights for 27 years. The aircraft is regarded by many people as an aviation icon and an engineering marvel.

    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.

    How do we know what is deep inside the Earth? And who discovered it?
    The Earth has 3 main layers based on chemical composition: crust, mantle, and core. Other layers are defined by physical characteristics due to pressure and temperature changes. This animation tells how the layers were discovered, what the layers are, and a bit about how the crust differs from the tectonic (lithospheric) plates, a distinction confused by many.

  • Earths core deprived of oxygen

    2:15

    The composition of the Earth's core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well. Oxygen is the most abundant element in the planet, so it is not unreasonable to expect oxygen might be one of the dominant light elements in the core. However, new research from a team including Carnegie's Yingwei Fei shows that oxygen does not have a major presence in the outer core. This has major implications for our understanding of the period when the Earth formed through the accretion of dust and clumps of matter.

  • Satellites find molten iron liquid jet-stream at Earth’s core - TomoNews

    7:09

    European Space Agency satellites have detected a large jet stream of liquid iron flowing beneath earth’s surface at a quickening pace.

    The findings were published in the research journal, Nature GeoScience.

    The stream is around 10,000 feet deep and moving beneath Canada and Russia at pace of 30 miles per year, reported the New Scientist. It is 260 miles wide and is nearly 20,000 miles long.

    “We can explain it as an accelerating band of molten iron circling the North Pole, like the jet stream in the atmosphere”, lead researcher Dr Phil Livermore said in an article on the University of Leeds website.

    This molten jet stream could be caused by buoyant forces in the earth’s core, or variations in the magnetic field within the core, explained University of Leeds Professor Rainer Hollerbach explained in a ESA article detailing the findings.
