DESCRIPTION

Did you know that you are four times more likely to die from an asteroid impact in your lifetime than to be struck by lightning? This is one of the startling facts to emerge from our new 13-part series which tackles some of the questions that have puzzled scientists for years.

This is one of the startling facts to emerge from our new 13-part series which tackles some of the questions that have puzzled scientists for years.

With contributions from some of the world's foremost scientists, the series examines the newest developments and theories and uses moving human-interest stories, personal experiences and the latest computer-generated graphics to bring a range of subjects vividly to life.

In Killer Asteroid, we track down the scientists who are trying to find ways of preventing a large asteroid from destroying our planet. 'Fifty million tonnes of rock coming at 60,000mph,' says geologist, Ray Anderson. '[That's] ten times all of the nuclear weapons on Earth at the height of the Cold War going off in one spot.'

Stonehenge is England's most mysterious ancient monument, standing on a site older than the Pyramids of Egypt. But who built it and how? We know that some of the rocks were brought to Stonehenge from more than 200 miles away, across England's biggest tidal estuary. We demonstrate how late Stone Age-early Bronze Age Britons could have transported the stones over such a long distance, and raised them into place using primitive technology, some 4500 years ago. Then, using a three-dimensional computer model, facial anthropologists examine human skeletons which have been found near Stonehenge. watch as they recreate the face of a man who may have worked on the construction of this enigmatic ancient structure.

    Naked Science travels back in time to look at three of the largest mass extinctions that have decimated life on the planet in the past. What caused these wipe-outs and could they happen again in the future, threatening our very survival?
  • Naked Science: Meltdown
    Imagine a world where melting ice caps have raised sea levels by 20 feet, where the combined effects of floods and storms inundate large areas of the world’s low-lying coastlines and where the great cities of the world are under water. Is this the fate that awaits mankind? It is a nightmare scenario - but what is the scientific basis for these fears of sea-level rise?
  • Naked Science: Hubble Trouble
    The Hubble Space Telescope has stared out over billions of light years, to the far reaching corners of the Universe. Some have called it the most important scientific instrument ever built, deepening our understanding of our place in the cosmos. Naked Science meets the engineers who put this telescope in space, the astronauts who fixed its faulty eyesight and the astronomers who used Hubbles unrivaled spatial resolution to unlock the secrets of the Universe.

    Comets 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. Thsi episode of Naked Science explores what a comet actually is and what secrets they hold for our understanding of how the solar system was formed.
  • Naked Science: Triumph of The Tanks
    The tank has been in existence for almost 100 years. They changed the face of warfare but how can science explain their effect? After every major war the tank is written off by its critics as a relic, but with every generation it reinvents itself and is victorious on the battlefield once again. Naked Science gets into the worlds best tank and asks how technology has made these machines triumphant.
  • Naked Science: Deep Space Probes
    Robotic Space Probes have opened a whole new frontier for Mankind. Naked Science will follow the construction, journey, and eventual arrival of the two biggest Probe missions ever to be launched into our heavens: The Cassini-Huygens Mission and the Mars Exploration Rovers.
  • Naked Science: Deadliest Planets
    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 kind of worlds 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.
  • Naked Science: Evolution:Was Darwin Wrong?
    Our planet Earth is teeming with life. To some, it's a miracle - but can science explain how it came into existence? Critics have attacked the theory of evolution for 150 years. They claim it is full of holes, and the gaps reveal the hand of an Intelligent Designer. Who's right? We investigate the most explosive science of them all and ask, was Darwin wrong?
