S01E01 Killer Asteroid 15/09/2004 An untold number of asteroids have slammed into Earth over millions of years. Scientists are now monitoring the skies watching for the next 'big one', and considering options on how to prevent the next major impact.
S01E02 Super Volcano 22/09/2004 National Geographic Naked Science presents "Super Volcano", the inside documentary of what might happen if the Yellowstone Caldera were to erupt one day. This documentary includes a Yellowstone timeline of past eruptions, how Yellowstone would affect the world, and what impact will it be for the U.S.
S01E03 Angry Earth 29/09/2004 The science of earthquakes is examined in this episode. Archival footage highlights damage from the great 1906 quake in San Francisco, as well as 1964's deadly quake in Alaska. Despite efforts to 'quake-proof' bulidings, some simply don't survive; why this happens is explained. Also discussed are tsunamis, caused by undersea earthquakes, and the threat they pose to coasts worldwide. Efforts by scientists to predict earthquakes are also investigated.
S01E04 Who Built Stonehenge? 06/10/2004 The general belief is that Druids built the ancient circle of stones. Recent archeological discoveries and new technologies reveal Stonehenge to have been built long before Druids arrived. Did the technology to build such a structure exist 4000 years ago?
S01E05 The Deadliest Shark 10/11/2004 Experts compare the deadliness of bull, white, and tiger sharks, as well as profile their biology and behavior. The cause of shark attacks and what can be done to prevent them is discussed. Since sharks generally cover territories of several hundreds of miles, efforts to rid them from particular beaches are usually unsucessful. Sharks also use their mouths to examine their surroundings and determine what is and isn't food, leading to many shark attacks against humans.
S01E06 Bermuda Triangle 17/11/2004 Several possible reasons for the Triangle's reputation as a danger zone are investigated. Scientists have discovered that the area's magnetic field has dropped considerably in the last 20 years. Could activity involving underwater volcanic vents be affecting the field and posing a threat to vessels? UFO's, as well as bizarre weather conditions, are also considered as possible explanations.
S01E07 Atlantis 24/11/2004 In 350 B.C. Plato wrote about an ancient civilization that disappeared in one day in a catastrophic event. Is the story simply a myth or have remains of a real Atlantis been discovered? This episode examines the city that Plato described and analyzes a four leading sites that present-day explorers believe could be the remains of the ancient city.
S01E08 Alien Contact 01/12/2004 A mysterious crash in Roswell, NM 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.
S01E09 Angry Skies 22/12/2004 Some of the worst nature can offer is spawned from the skies above. Though their damage is concentrated, a tornado's strong winds can turn debris into deadly missiles. With hurricanes, a huge amount of energy is discharged over hundreds of miles causing widespread devastation. What are the precautions can we take to protect ourselves?
S01E10 What is Human? 08/12/2004 The story of human evolution traces the development of our species from our earliest ancestors through their mastery of tools and their environment. Through five million years, the essence of what it means to be human is analyzed.
S02E01 Earth's Core 05/01/2005 The Earth's core is some 4000 miles beneath our feet. Beneath the rocky surface lies massive amounts of liquid metals that generate a protective magnetic field. That field shields the planet from dangerous space radiation. Without it, Earth would be as barren as Mars. But with the inner core cooling, is that scenario inevitable?
S02E02 Surviving Nature's Fury 12/01/2005 We have no natural defenses to the deadly extremes offered up by nature. Lightning bolts, excessive heat, severe cold, water, hail and wind are all examined for their respective threats to the human body.
S02E03 Shark Attacks 22/01/2005 This episode takes you to the shark bite capitals of the world for "up close and personal" views of bull and tiger sharks, and the infamous great whites. A camera is also inserted into the stomach of a live shark to get an inside view of how this highly-evolved killing machine operates.
S02E04 Telepathy 16/02/2005 The supposed ability of some individuals to mentally transmit and receive thoughts is examined in this hour. Unsubstantiated claims are not proof, so several experiments are conducted to put the phenomenon to the test. This includes exploring the telepathic connection that some twins claim to experience through a series of tests on one twin and recording the other twin's reaction, and a Ganzfeld test where a person in one room attempts to transmit mental pictures to another person in a different room.
S02E05 Volcano Alert 10/03/2005 Galeras, Fuego, St. Helens, Kilauea, Popocatepetl. These are names of currently active volcanoes. They all have the ability to end human life, destroy millions of dollars of property, and instill fear. Volcanoes are necessary to build mountains, create new geological features, and are, figuratively speaking, the veins of our planet. Despite the brilliance and vividness of volcanoes, there is an intensity that cannot be escaped. This intensity has caused the deaths of over 30,000 people in just the last two decades. That's why it's important for scientists to be able predict when a volcano will erupt. To get an idea as to what's happening beneath the surface, vocanologists measure the temperature and gas content of magma as it rises in underground chambers, as well as changes in the movement of the nearby surface. Their goal is to recognize all the predictable signs of an eruption and, like a jigsaw puzzle, put them all together into predictions that are accurate.
S02E06 Spacemen 29/08/2005 Even if we found the perfect Earth-like planet among the stars, how would we survive the trans-galactic journey? Scientists are working on making the mission to Mars and beyond a reality.
S02E07 Bullets 12/09/2005 Two centuries of science has changed the bullet from a basic round ball into a highly-specialized form of ammunition. The advancements that have made modern-day bullets so efficient and deadly are examined.
S02E08 Tsunami Warning 17/10/2005 Ever since the tragedy on December 2004 when huge waves pummeled the coastline of the Indian Ocean, people have been left with three questions: how, why, and what can we do to prevent it from happening again. The first is simple enough. However, the other two require more thought and initiative. The reasons may never be fully understood, but as human beings we have the ability to minimize or possibly even prevent the loss of human life should this merciless disaster ever strike again. Naked Science investigate what exactly the governments of the world are doing to get warnings out to people within hours, days, possibly weeks before one happens again. Scientists worldwide are for the first time working together to develop an understanding of the circumstances that take place to create tsunamis and consider what it takes to prevent the loss of human life and property.
S02E09 Birth of the Earth 24/10/2005 Naked Science examines evidence that has survived over 4 billion years to answer questions that have plagued scientists and philosophers alike, such as: why we are here, what caused our planet to come to existence, what caused the diversity of life and natural spectacles available on this pristine ecosystem we call earth, and what exactly does it take to support human life. Via direct and indirect evidence and interviews with many of the best minds of science, Naked Science aims to not only answer these questions, but answer the questions that drive the human spirit.
S02E10 Landslides 31/10/2005 Unlike many other natural disasters, landslides offer no real advance warning. Often triggered by heavy rainfall, landslides pose a danger to those who live in areas where humans have altered the local geography. In addition to video taken of landslides in progress, this episode highlights efforts being made to protect motorists from rocks and boulders falling onto roadways.
S02E11 Loch Ness 07/11/2005 Are there actually strange creatures swimming in Loch Ness? This episode examines the photographic evidence and the many high tech attemps to gain proof of Nessie's existence. Using computers, the famous photos and films are analyzed and the results are less than convincing.
S02E12 Close Encounters 17/12/2005 Why do so many people claim to have been visited or abducted by aliens? Are these sightings mere hallucinations or something more? Experts interviewed consider most to have been concocted by the brain operating in a culture awash in UFO images and folklore. Studies show that dreams can be triggered by something as simple as electromagnetic waves. But if aliens want to contact us, how can they do this? One way is through radio waves. SETI investigators scan the skies searching for a signal from intelligent life form. Perhaps beings more advanced have discovered how to manipulate time and space to find shortcuts to overcome the barrier of distance between locations in the universe. Or maybe they have sent tiny robots to investigate our planet.
S03E01 Moon Mysteries 15/01/2006 The moon's effect on Earth has been considerable. It's gravitational pull may have made life on our planet possible. In more modern times, some think it affects our behavior. Still others think it causes earthquakes and volcanic eruptions.
S03E02 What's Sexy? 13/02/2006 Naked Science investigates the perplexing science behind human sexual attraction. To solve the mystery of sexuality Naked Science explores all aspects of attraction such as the beating pulse, sweaty palms, hormone extravaganza, and nervousness.
S03E03 Death of the Sun 20/03/2006 It generates heat and sustains life on our planet. But like humans, the sun has a limited lifespan. As our star ages, it will become hotter and expand, evaporating all of our oceans and killing all life on planet Earth. Don't panic yet--we have a few billion years before this happens.
S03E04 Big Freeze 29/03/2006 As odd as sounds, global warming may be rushing the planet into the next ice-age. The Big Freeze could come with no warning, resulting in a massive extinction of species and changing life on Earth. Is the next cold snap nearer than we think?
S03E05 Roman Tech 26/04/2006 Before you label it "modern technology", you might want to check your history books. 2000 years ago the Romans developed much of what makes modern urban life possible and comfortable. Their achievemnts range from flowing clean water to the bikini.
S03E06 Lightning 24/05/2006 In over 200 years of study, scientists are still unsure of what stimulates a lightning strike. One current theory suggests that cosmic rays could be the trigger. The odd phenomenon of ball lightning is examined, as well as recently discovered sprites that emanate upward from clouds and into the middle atmosphere.
S03E07 The Deep 28/06/2006 The last great unexplored territory on Earth lies in the depths of the planet's oceans. The bottom of the sea is home to explosive volcanoes and massive earthquakes generating tsunamis that cause massive destruction along the coasts. These extreme depths are inhabited by large and long-lived creatures, many still unknown to science.
S03E08 Explosive Force 05/07/2006 Explosives have gone from gunpowder to the A-bomb in relatively short order. The future may lie in the stuff of science-fiction: anti-matter. Scientists are currently at work on this even more powerful and deadly explosive force.
S03E09 Pyramids 12/07/2006 In the space of 500 years, eighteen of these huge monuments were built. Focusing more on the "who" than the "how" of their construction, forensic anthropology learns that it wasn't slaves that built the pyramids, as originally thought. The facilities that housed the workers have been unearthed, giving a clearer picture of the mammoth project that was pyramid building.
S03E10 Colliding Continents 19/07/2006 All of the Earth's landmasses were once clumped together, forming one giant "supercontinent" known as Pangea. Slowly, it was torn apart, broken up into the modern day continents. Those same forces are still at work beneath the planet's surface, moving the continents and constantly reshaping our planet as they collide, buckle, and rise up to form new mountain ranges. Looking ahead hundreds of millions of years, the Earth will look nothing like the one we know today, the continents having reshaped the surface completely.
S03E11 Birth of the Universe 06/09/2006 This episode attepmts to answer the question, "Where did everything in space and on our planet come from?" Travel back to the very beginning of the universe when it all started. Also, astronomer Edwin Hubble offers his thoughts that the universe used to be much smaller than it is now.
S03E12 Freeze Me 20/09/2006 Some dearly departed have had their bodies put into a deep freeze, hoping one day medicine will have a cure for what ailed them. Critics consider the use of cryonics to bring back the dead a fool-hearty idea. It's an unproven science that faces many obstacles to success, especially in the formation of ice crystals that damage the body's cells. Cameras follow cryonicists to document the processes they employ in prepping a body for freezing. On the more practical side, scientists are making real progress in preserving individual organs for later transplantation into sick individuals.
S03E13 Forensics Under Fire 12/10/2006 Since the advent of DNA analysis, many of the traditional forensic techniques have been shown to have a questionable scientific basis. This episode examines several long-trusted methods, including fire and firearm investigations, and tests to see how they hold up.
S03E14 Ancient Asteroid 21/10/2006 Incredible heat was needed to turn sand in an Egypt desert into yellow-green glass. Searching for clues as to what could generate such heat, scientists first looked at the 1908 Tunguska event in Siberia; the wide-spread destruction is believed to have been caused by an exploding asteroid. Viewing the 1994 collision of a comet with Jupiter provided scientists with answers. The huge fireball that it generated was validation of their theory that an asteriod impact some 30,000 ago could easily have turned an Earth desert into glass.
S03E15 Extinctions 02/11/2006 Dominant life forms have been wiped out before as our planet has a history of mass extinctions. A huge asteroid impact is credited with the passing of the dinosaurs, but what caused the others? This hour examines three of the major extinctions in the Earth's history and the possibily of another occurring.
S03E16 Deadliest Planets 06/12/2006 Earthlings may one day develop the technology to visit other planets, but could we survive their hostile environments? This hour examines the extreme surface conditions of the planets within our solar system, as well as some that lie beyond.
S03E17 Was Darwin Wrong? 07/12/2006 For well over a century, critics have charged that Charles Darwin's The Origin of Species can't possibly explain the development of life on our planet. They counter with the belief in "Intelligent Design". This hour seeks to put science to the test to see how wrong, or right, Darwin was.
S04E01 Glacier Meltdown 31/01/2007 Naked Science reports on the chilling evidence that many of the world's mountain glaciers are melting at a faster rate than any time in the past 150 years. A veteran Arctic and ice sheet expert in Greenland explains how the melting rate of the ice affects the rate of sea levels rising in the future. And the episode explains the devastation of that impact on the world.
S04E02 Destructive Forces 21/02/2007 Wind, water and ice have each played a part in the reshaping of Earth since the beginning. Whether it be erosion caused by rivers, wind producing storms or the scouring effects of glaciers, these elements have brought great destruction and change to the planet's surface.
S04E03 Stone Age Apocalypse 28/02/2007 Human evolution is believed to have begun some six million years ago. Despite the passage of so much time, the amount of diversity among the DNA of all humans is minuscule. Some 75-thousand years ago, something apocalyptic occurred that left relative few humans alive to carry on the species. The cause of this "bottleneck" is now believed to have been a massive volcanic eruption on the Indonesian island of Sumatra.
S04E04 Comets 07/03/2007 Scientists are only now starting to unravel the secrets of comets. Often referred to as dirty snowballs, they contain ice and elements from the very start of the universe. Some theorize that a comet, crashing into our planet, brought with it the organic material that started life on Earth. Spacecraft continues to offer new information on their makeup, from bringing back samples from a comet's tail to direct contact when a NASA-launched craft slammed into the comet Tempel-1.
S04E05 Prehistoric Americans 14/03/2007 It has long been said that the first Americans were hunters who arrived on the continent some 13,500 years ago via the Bering land bridge. This idea is now being challenged by scientists using modern, high-tech forensics to arrive at a new conclusion; the first residents may have arrived thousands of years earlier and had a more developed grasp of engineering that we had thought possible.
S04E06 Deep Space Probes 27/03/2007 Great distances and dangerous environments make robotic spacecraft the best way for scientists to explore our solar system. Acting as our eyes and ears, these probes have revealed secrets about the distant planets and their moons, their surfaces, weather and environments.
S04E07 Polar Apocalypse 01/04/2007 Scientists monitoring global warming predict further melting of the polar icecaps. The effects of a rising sea level on the world's coastlines is investigated.
S04E08 Dino Meteor 12/04/2007 Scientists have long thought that dinosaurs were hurled toward extention after a huge meteor collided with Earth. Now, some theorize that a meteor impact may have given rise to the huge creatures.
S04E09 Planet Storm 26/04/2007 Some 3.9 billion years ago, our solar system was assaulted by a gigantic asteroid storm. This episode examines how life on our planet survived and the chances of another such attack occurring.
S04E10 Killer Lakes 03/05/2007 Millions live in lakeside towns, enjoying the scenery and recreational activities the water provides. Unfortunately, danger lurks beneath the surface of many of these seemingly harmless bodies of water. This episode examines several of the lakes in the United States considered to be potentially dangerous, including those of Yellowstone and Mount Ranier.
S04E11 Ring of Fire 02/08/2007 A volatile chain of volcanoes and faults ring the top of the Pacific Ocean. With more than one billion people potentially in harm's way, evidence suggests that this region is becoming more active. Earthquakes, tsunamis and volcanic eruptions are being studied by scientists who hope to learn more about the processes at work before a devistating event happens.
S04E12 Comet Mysteries 09/08/2007 This episode examines the chances of a comet hitting Earth again. It's happened before many times, once even wiping out the dinosaurs. How astronomers could spot new ones as they barrel through space is shown. The question remains, how could they could they stop one even if they find it?
S04E13 Alien Safari 09/08/2007 With advanced technology in their hands, astronomers and scientists may now be capable of detecting extraterrestrial life in the universe. In fact, some think the proof may be found in as little as a decade. Astronomers involved in the effort, including those at SETI (Search for Extraterrestrial Intelligence), discuss the possibilities and the likely spots for finding life outside of Earth.
S04E14 Hyper Hurricanes 18/10/2007 At one time, America was bombarded by some of the most severe storms ever to hit the planet. Scientists wonder if hurricanes are increasing in intensity and perhaps becoming the monsters they once were. The effects of global warming on the severity of hurricanes, if there are any, are discussed.
S04E15 Dangers of the Deep 25/10/2007 More humans have traveled to the moon that have been to the ocean's floor. Virtually unexplored, the trenches trenches of the oceans could swallow Mt. Everest. Despite the crushing pressure, Earth's final frontier holds great potential for meeting the planet's energy needs and perhaps to cure diseases.
S04E16 Solar Force 30/10/2007 The level of cosmic rays emitted by the sun is anything but constant. Scientists are just now discovering the ways in which the sun's fluctuating output affects our planet's weather and overall climate.
S04E17 Birth of the Solar System 06/11/2007 Thanks to new developments in the technology of astronomy, scientists have been able to collect new information, giving them clues to how our solar system was formed.
S04E18 Hubble Trouble 06/11/2007 The famous telescope that orbits the Earth was initially considered a failure because of its long list of problems. The scientists who designed the device and those who ultimately fixed it discuss the project, as well as the surprising photos and information it has been able to collect about the universe.
S05E01 Grand Canyon 11/02/2008 The Grand Canyon is a natural wonder so large it can be seen from space. Examining the layers of rock exposed from centuries of of erosion, geologists trace the canyon back to its early days when the Colorado River first began to flow through the region.
S05E02 The Rockies 28/02/2008 Scientists examine the formation of America's largest mountain range. New evidence suggests that they continue to grow and at a faster rate than their Canadaian counterparts.
S05E03 Birth of America 06/03/2008 The shape of the North American continent has changed radically over millions of years. During the great Ice Age, glaciers carved out the Great Lakes; as the Earth's temperature rose, they filled with glacier melt. The Great Salt Lake is just a shadow of its former self. And as tectonic plates continue to move, America moves closer to Europe each year.
S05E04 Birth of Life 13/03/2008 The age-old question of what brought about life on our planet is examined. Scientists search of the mechanism that triggered non-living matter to change into into living creatures.
S05E05 Pluto Rediscovered 20/03/2008 Three million miles from earth lies a planet so small that even the most advanced telescopes. A dedicated core of scientists offer educated guesses as to the makeup and condition of Pluto, as well as discuss its qualifications to be counted as a planet. Meahwhile, the New Horizons space probe continues its nine year trek to the planet to finally reveal the secrets of the "planet".
S05E06 Mars: Waterworld 25/05/2008 After blasing off from Earth on 8/4/2007, NASA's Phoenix Lander is scheduled to enter Mars' atmosphere on 5/25/2008 and land on the polar ice-cap. If all goes well, the solar powered robot will extend its nearly eight foot scoop and dig into the ice amd soil, seaching for the building blocks of life: carbon, nitrogen and, most importantly, water. Phoenix's goal is to prove that life either was, or perhaps is, posssible on the red planet. If it succeeds, it will change our understanding of life in the universe and its uniqueness to our planet.
S05E07 Saturn's Secrets 25/05/2008 NASA's Cassini spacecraft, launched in 1977, used the gravitational pull of Venus to act as a sling shot to travel the 2 billion miles to Saturn. Its arrival in 2004 allowed an unprecedented study of the planet's mystical rings and details of what lies below Saturn's seemingly smooth exterior. What has been learned so far (the probe continues to orbit and study) is analyzed, as well as information gleaned from the Huygens probe which landed on its moon Titan.
S05E08 Asteroid Alert 27/05/2008 Even a small asteroid slamming into our planet at thousands of miles-per-hour could produce a major catastrophe, wiping out a city and killing millions. Experts examine evidence that an early civilization in North America became extinct because of an asteroid impact during the last Ice Age. With no crater to examine, scientists test the theory that it exploded into a glacier. NASA's current efforts to find and track all near-Earth objects is highlighted and what could be done to prevent such a disasterous impact.
S05E09 First to Cross the Ocean 28/08/2008 The arrival of humans in Australia was a milestone in mankind's eventual inhabitation of the entire planet. This episode determines if the settlement of Australia was by accident or an intentional plan , how it was done, and what factors are necessary for a sucessful civilization to sustain itself.
S05E10 Time Machine 11/09/2008 The idea of traveling through time has long been a fanciful dream of scientists and fiction writers. Since determining that we live on a space-time continuium that can be warped by gravity, thinkers have pondered how to make that happen. Now scientists are wondering if lasers would allow us to twist the fabric and make possible leaps forward and backward in time.
S05E11 Earth's Invisible Shield 18/09/2008 Since the formation of the planet, Earth's magnetic field has shifted poles thousands of times. The last time it happened, humans weren't around. Now with the field weakening, scientists believe another flip is near. Soon, several satellites will be launched with magnetometers to detect even subtle changes, helping experts predict when the field may reverse.
S05E12 Big Bang 25/09/2008 Everything in the universe can be traced back to the first second following the Big Bang. The building blocks of the universe, atoms, were formed as pure energy was converted into matter. The key to understanding how this happened was revealed by Albert Einstein's most famous equation, E=MC2, showing that energy and mass are different forms of the same thing.
S05E13 Hubble's Amazing Universe 05/10/2008 One of the most impressive and technologically advanced devices ever made, the Hubble Space Telescope has viewed objects never-before seen. It continues to provide views of the most distant objects from the early days of the universe, bringing about new sets of questions for scientists to answer.
S05E14 Supercontinent 09/10/2008 Long ago, the continents of the Earth were joined together in one huge mass. Some experts predict that it will happen again 250 million years in the future. Will it result in mass extinctions as in the past?
S05E15 Giant Crystal Cave 12/10/2008 Scientists explore a Mexican cave that is home to some of the largest crystals ever discovered. They use special protective suits and equipment to enter the harsh environment where temperatures hover around 120 degrees Fahrenheit and humidity exceeds 80 percent. Their goal is to determine how these ancient crystals were formed.
S05E16 Death of the Universe 16/10/2008 This episode concentrates on how the universe was made in the Big Bang and how scientists predict it could end similarly as it continues to expand. Several theories are covered including the "Big Crunch" where the universe shrinks back to its original size, and the "Big Chill" with the universe slowly freezing to death.
S05E17 What Killed the Aztecs? 13/11/2008 It's widely believed that the awesome Aztec civilization was wiped out during the 1500s by diseases introduced by Spanish Conquistadores. Eighty percent of that Central Mexican population died in the devestating epidemics that followed their arrival. Research by a pair of scientists, however, suggests that their fate was not a result of visitors from the New World. If their conclusions are correct, the same ting that killed the Aztecs could happen again in this century.
S06E01 Solar Storm 05/02/2009 Solar storms, disruptions of the complex magnetic fields on the Sun, cause serious problems on Earth. One storm approximately 150 years ago fried telegraph lines around the world. Another in 1989 resulted in a massive power blackout in Canada. Implementing a Japanese satellite trained on the Sun's surface, scientists are hoping they can predict when and where the next big one will erupt.
S06E02 Super Diamonds 26/02/2009 The hardest known substance on Earth is known for its value and beauty. Scientists believe diamonds could also hold incredible possibilities for the future. Their incredible durability and their unique properties could revolutionize everything from computer chips to space explorations. All diamonds, however, contain minor flaws. What science must do is create a perfect "super diamond"
S06E03 Birth of the Oceans 05/03/2009 When the Earth was being formed, it was too hot to include water in the mix. Scientists came to believe that the liquid covering most of our planet's surface was brought here via comets. Recent research reveals that the moisture held by comets varies somewhat from the liquid that now fills our oceans, so where else could the water have come from? New theories incorporating different sources have been proposed.
S06E04 Ice Age Meltdown 09/03/2009 The Ice Age came to a sudden end some 18,000 years ago. Ice caps melted, driving up ocean levels and glaciers receded, sculpting the land and forming the features we recognize today. There was a major extinction of species that could not adapt to the rapid change in environment. With the planet heating up again, scientists hope to learn about the past to help us cope with future changes.
S06E05 The Death of Earth 11/03/2008 The traditional thinking said that as the sun aged and its gravitation pull weakened, the Earth would gradually slip away and meet its end. Using cutting edge models, experts in climatology, biology, geology and astronomy are able to project millions, perhaps billions, of years into the future. They conjecture that supercontinents will form and then splinter, the oceans will float into space, and all life will become extinct from the planet.
S06E06 Journey to Jupiter 12/03/2009 The Galileo probe was the first craft to orbit an outer planet, making incredible discoveries about the liquid and gas Jupiter that's 90,000 miles across. It found evidence of liquid water on Europa, one of the planet's 63 moons, and intriguing motions underneath Jupiter's surface raised speculation of possible life under the sueface. This episode looks below the clouds to discover what is happening on the giant planet.
S06E07 Death of a Star 12/03/2009 New evidence about the star Mira shows a brief but important moment in the death of a star. At some point, our sun will reach the same milestone and it has grave implications for life on Earth.
S06E08 Monster Black Holes 26/03/2009 Astronomers continue to study black holes to understand what role they play in the universe. Scientists understand that their incredible pull can swallow nearby stars and entire galaxies and that they warp time and space. Investigators use the equations of Einstein and theories of Hawking to figure out what the inside of a black hole looks like and what time, place, or dimension lies on the other side.
S06E09 Great Lakes 02/04/2009 As the glaciers retreated some 14,000 years ago at the end of the Ice Age, the Great Lakes were revealed and began to fill. Scientists still debate about the formation of the world's largest bodies of fresh water. Perhaps they were carved out by those massive glaciers or maybe they were caused by an ancient comet that exploded in that area.
S06E10 How to Kill a Planet 23/04/2009 The Earth is built to last. It is 4.5 billion years old. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and it still orbits happily around the sun. But physics is a curious thing and it can harness devastating power -- enough even to destroy the world. Naked Science will analyze antimatter, black holes and even more amazing means of destruction -- and the havoc they could wreak on a planet. So strap in, buckle up, and enjoy the ride to doomsday.
S06E11 Earth's Crust 07/05/2009 An imaginary vehicle circling the planet is used to highlight the surprises that exist beneath the Earth's crust. Life is discovered in the crust deep in a South African gold mine; a huge gun is fired to determine how crust reacts to an asteroid. Another scientist proposes a new theory to explain how diamonds move from the Earth's mantle to the surface.
S06E12 Anatomy of a Hurricane 04/06/2009 With the power of a nuclear bomb, hurricanes cause incredible damages in several ways: the storm surge, the winds themselves, and the massive flooding which causes the most causalities. This episode examines the forces at work inside the monster storms that result in such power and destruction.
S06E13 Twister Outbreak 11/06/2009 Super Tuesday (2/5/2008) saw an unprecedented outbreak of 87 tornadoes in five states. What was most shocking was where many of them happened: in Kentucky, outside of the traditional "tornado alley". Storms have been growing stronger in recent years, clocking wind speeds of 300 mph. Scientists examine factors involved in the changes,including global warming and the northward movement of the jet stream.
S06E14 Earth's Evil Twin 25/06/2009 Venus and Earth are roughly the same size but have gone on different paths over billions of years. On its hostile surface, it rains battery acid and temperatures reach 900 degrees. The Venus Express spacecraft in 2006 detects lightening, leading scientists to wonder if chemicals supporting life are possible. Organisms could not survive on the surface but in the clouds its much cooler and water vapor exists.
S06E15 Secret World of Fireworks 02/07/2009 Focusing on Zambelli Internationale of New Castle, Pennsylvania, the U.S. leaders in fireworks displays, the episode examines the closely guarded recipes and techniques used to stage spectacular shows. The behind-the-scenes work required to make one of the Zambelli displays go off without a hitch is revealed. Rocket scientists from Los Alamos, New Mexico also are interviewed.
S06E16 Tsumani from Outer Space 09/07/2009 Many scientists, including those at NASA, believe that large meteors plow into the Earth rarely, only every 50 to 100 thousand years. A group of scientists headed by Dr. Ted Bryant believe it's much more often than that. They've found evidence that a huge meteor hit a mere 500 years ago, causing a devastating tsunami that struck Australia. The scientists search coastlines and oceans floors for evidence of previous impacts.
S06E17 How the West Was Made 16/07/2009 Both catastrophic and gradual forces have been at work to form the American West's most famous landscapes. This episode looks at the greatest volcanic eruption in history that occurred near the San Juan Range of the Rocky Mountains, the staggering flood of 500 cubic miles of water that carved out the Washington Scablands, and the slow effects of wind erosion that has resulted in Monument Valley.
S06E18 Living on the Moon 19/07/2009 NASA plans to establish an outpost for humans on the moon by 2020. There are many new developments that need to take place beforehand, like developing a rover that can travel long distances and a system for finding frozen water at the poles.

S06E20 Incinerator Earth 22/10/2009 No one knows where the asteroid came from that hit the Earth 65 million years ago and wiped out the dinosaurs. They aren't even sure how it wiped out the species. New evidence suggests that dinosaurs' days were already numbered some 100 million years before the catastrophic collision. Scientists tell how it happened and predict what would happen if another 8-mile-wide asteroid were to hit our planet today.
S06E21 Earthquake Swarm 05/11/2009 Weekly earthquakes began rattling Reno, Nevada in 2008. Soon, several tremors strong enough to be felt were happening each day. The frequency soon escalated until hundred had been recorded. Seismologists have been monitoring the swarm and wondering if this is all building up to one major quake and the destruction of the city.
S06E22 Dirty Bomb Attack 12/11/2009 This episode examines the effects of a hypothetical radiological attack from a car bomb on a major U.S. city. The purpose is to give useful information in the event that such an event should occur. The stories of several characters are told to dramatize the effects on various types of people: those responding in the "hot zone", a person near to the blast whose symptoms develop over time, a pregnant woman who must evacuate, and investigators who comb through debris to determine who set the blast.
S06E23 Countdown to Impact 03/12/2009 In 2008, and for the first time in history, scientists were able to track an asteroid on a collision course with Earth. It hit in the desert in Sudan, very close to where experts predicted. Scientists believe we should be much more concerned about these smaller asteroids and the possibility of them impacting a populated area. They believe emergency management programs should be planning for such an event, just as they would a hurricane or earthquake. This episode looks at what could happen if an area like San Francisco should need to be evacuated because of an impending collision.
S06E24 Vesuvius Time Bomb 10/12/2009 Overlooking the picturesque city of Napels, Italy is the active volcano Vesuvius. Its history includes hundreds of eruptions, the most well-known being the eruption in 79 A.D. that wiped Pomeii off of the map. Scientists have no doubt it will erupt again and will cause even more death and destruction as the area's population continues to grow. Their job now is to try and predict when the inevitable will happen.
S06E25 Ancient Astronomers 17/12/2009 France's Lascaux region is home to the famous caves decorated with drawings by prehistoric man. Scientists and historians have long though they represented the simple concerns of the people of that time: hunting and gathering, for example. Now, some scientists believe the drawings represent much more than that; they believe they show an advanced knowledge of the night skies and of the stars which moved through the skies.
S07E01 Surviving Ancient Alaska 28/01/2010 Archaeologists at Denali Nation Park have unearthed evidence of hunter-gathers who inhabited the area 14,000 years ago.
