• Dark Future of the Sun

    Premiere Date:September 23, 2010

    Our Sun has served Earth well for almost five billion years. It's bathed us with heat and energy. But like humans, our home star is mortal. In five billion years, it will stop nurturing its planetary offspring. The aging star will bloat out beyond the orbit of our planet incinerating all living things–including humans if we're still around.

  • Total Eclipse

    Premiere Date:September 16, 2010

    Once they were dreaded and thought to be dragons eating the sun–but modern science has dispelled mythology and we now look forward to total Solar Eclipses as one of the most spectacular phenomena in the heavens. Explore the complex movements of Earth, Moon and Sun that produce these unusual events and hear details why we may be the only intelligent beings in the known Universe to witness eclipses like we see on Earth. Man-made eclipses also figure into the science in the form of instruments called "coronagraphs." They blot out the sun and reveal its corona, uncovering secrets which, while enlightening, also warn of a disaster that could make our advanced technology crash and burn. Finally, travel into deep space, where the tiny eclipses caused by planets circling distant stars is now beginning to reveal hundreds more stars where "exoplanets" exist… perhaps even those in habitable zones like the Earth.

  • Asteroid Attack

    Premiere Date:September 02, 2010

    What are the latest discoveries in the deadly world of asteroids? Will a recently returned Japanese spacecraft become the first to bring an asteroid sample back to our planet? What would happen to America's East Coast if the massive asteroid impact that helped form Chesapeake Bay 35 million years ago struck today? And why did President Barack Obama choose an asteroid as the destination for the next great manned mission into space? Learning about these huge space rocks isn't just about science, it's about survival.

  • Secrets of the Space Probes

    Premiere Date:August 26, 2010

    They've discovered water on other planets, and snatched the actual building blocks of life from a comet's tail. But can space probes find a new Earth…and even make contact with alien life? In the 21st century, space probes are photographing, drilling and even sniffing new worlds in the quest for life, and scanning thousands of distant suns trying to detect Earth-like planets. It's only a matter of time before space probes unlock the secrets to extra-terrestrial life and the universe itself.

  • Time Travel

    Premiere Date:August 19, 2010

    One of the Universe's most enduring mysteries is Time Travel. In this episode, we explore the possibilities. Discover why Time Travel into the future is unavoidable in the Einsteinian world of Relativity. As for the past… the laws of physics do not tell us it's impossible, but the bizarre consequences of going into the past and altering the future make for mind-bending science. Finally, we go for the future by traveling to the nearest star, 4.3 light years away… in only 45 days. Our destination may be an Earth-like planet; a planet scientists are now hunting for, and may find in the next 3 to 4 years.

  • Magnetic Storm

    Premiere Date:August 12, 2010

    It bursts from the sun with the power of ten thousand nuclear weapons… and when it hits our planet, it could create the largest disaster in recorded history. A magnetic storm from the sun could wipe out electrical power, television, radio, military communication, and nearly every piece of electronics in the Northern Hemisphere. It's a "Solar Katrina" — a planet-wide "hurricane" of magnetic forces that scramble all 21st Century technology, possibly for good. What causes this magnetic superstorm? Why is magnetism so powerful — and yet so poorly understood? And is there anything we can do to prevent the Magnetic Storm?

  • Mars: The New Evidence

    Premiere Date:August 05, 2010

    In the last few years, the Red Planet has yielded up many new clues that life may have once existed there…and may even exist there today. There is now have proof that water once flowed on the surface, that Mars once had lakes, and that the frozen poles are mostly water, not carbon dioxide as previously thought. Mars has snow–an aurora–and lightning generated by dust storms. Most intriguing of all are the seasonal plumes of methane that just may point to bacteria living below the surface.

  • 7 Wonders of the Solar System

    Premiere Date:July 29, 2010

    We are in the midst of the greatest era of space discovery. 21st century spacecraft and sophisticated imaging technology are venturing into un-chartered territory every day–and much of the extraordinary phenomenon is happing right in our own cosmic backyard. Take an exhilarating, unprecedented exploration of the seven most amazing wonders of our solar system. Our virtual tour begins with a trip to Enceladus, one of Saturn's outer moons, where icy geysers spout from its surface. Then venture to Saturn's famous rings, which contain mountain ranges that rival the Alps. Next dive into the eye of the biggest storm in the solar system–Jupiter's Great Red Spot. Soar through the Asteroid Belt, containing millions of leftover rocks from the formation of the solar system. Trek up Mount Olympus, the largest volcano, located on Mars. Have a close encounter with the searing surface of the sun, and finish the journey by exploring our home planet Earth.
