Gravity 04/22/2008

Gravity

Premiere Date: 04/22/2008

Gravity is the most powerful and exacting force in the universe. It is pervasive and penetrating. Gravity binds us together, its reach hangs stars in the sky and its grip crushes light. Gravity holds planets together, and leashes them to their suns. Without gravity, stars, comets, moons, nebulae, and even the Earth itself would not exist. Explore how science and humanity discovered, overcame and utilized gravity. Learn what it takes to propel objects into the heavens, to ride a wave or to ski down a slope. Take a front row seat as an astronaut subjects himself to the weightless wonders of the specially modified aircraft used to train astronauts known as the "Vomit Comet."

Wildest Weather in the Cosmos 04/08/2008

Wildest Weather in the Cosmos

Premiere Date: 04/08/2008

Imagine a tornado so powerful, it can form a planet, or winds sweeping across a planet but blowing at 6,000 miles per hour! How about rain....made of iron? Sounds like science fiction, but this type of weather is occurring daily in our solar system. Scientists are just beginning to unlock the secrets of these planets and their atmospheres. Can this research help scientists solve long unanswered questions that we have about Earth? As our own planet churns with the effects of global warming, it's natural to look into the heavens and wonder about the rest of the real estate.

Nebulas 04/01/2008

Nebulas

Premiere Date: 04/01/2008

Take a tour through the "Art Gallery of the Galaxy" and view what are considered the "crown jewels" of the heavens. Nebulas are mysterious clouds of gas that aren't classified as stars, planets, moons or asteroids. Astronomers use the most sophisticated techniques to view them since they are practically invisible to the naked eye. Nothing less than stunning, nebulas glow, reflect or obscure the galaxy's light with amazing swirls of color. Nebulas mark the regions where the nothingness of space first coalesces, where stars are born and where stars die. Cutting-edge computer graphics are used to bring the universe down to earth.

Unexplained Mysteries 02/26/2008

Unexplained Mysteries

Premiere Date: 02/26/2008

Delve into the myths, misconceptions, truths and amazing mysteries of our unique universe. Could life exist on Mars? Is time travel possible and does Einstein's theory of relativity support it? Is there a companion dark star to our sun and could it pose a threat to earth? Learn about the spark that lit the big bang. Take a journey from science fiction that predicted all these things, to the scientific reality of what they mean to us in the ever-changing universe.

Constellations 02/19/2008

Constellations

Premiere Date: 02/19/2008

A constellation is a group of stars that are connected together to form a figure or picture. These star pictures help organize the night sky and provide a useful tool for astronomers even today. Explore some of the 88 official constellations and learn about some of the highlights of each--like the star that's due to go supernova in the constellation Orion. Discover the 13th zodiac sign that no one talks about, and find out why Polaris, the North Star, will one day have to surrender its title.

Supernovas 02/12/2008

Supernovas

Premiere Date: 02/12/2008

A stellar explosion, the supernova is the sensational death of a star. It can shine as bright as 100 billion Suns and radiate as much energy as the Sun would emit over 10 billion years. Jets of high-energy light and matter are propelled into space and can cause massive Gamma Ray Bursts and emit intense X-ray radiation for thousands of years. Astronomers believe that this process creates the very building blocks of planets, people and plants. Meet the world's leading Supernova hunters, and take a look at recorded supernovas throughout history.

Space Travel 02/05/2008

Space Travel

Premiere Date: 02/05/2008

When man finally broke free of the Earth's gravitational pull the dream of traveling to other planets became a reality. Today scientists are proposing a bizarre array of technologies in the hope of traveling faster through space: from space craft sporting sails that catch laser beams, to propulsion engines powered by a bizarre entity known as anti-matter. Finally explore the science behind the seemingly fanciful notion of warp-drive and a theoretical particle that can travel faster than light.

The Milky Way 12/18/2007

The Milky Way

Premiere Date: 12/18/2007

We used to think that Earth was at the center of the universe, but now we know we're not even at the center of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic center of our solar system. Within the Milky Way can be found the debris of old, dying stars fueling the birth of new stars and at the galactic center hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Mysteries of the Moon 12/11/2007

Mysteries of the Moon

Premiere Date: 12/11/2007

For thousands of years, mankind has found comfort in its presence. It's been a lantern for nighttime travelers, a timekeeper for farmers, and a location finder for sailors at sea. For some cultures, it's even been a god. It's the only cosmic body ever visited by human beings. From afar, the Moon's luminance has captivated us since the beginning of time. And a closer look at the beacon in the dark sky reveals an ever-present source of myth, intrigue, controversy and unsolved mysteries. The field of science may cast an empirical light on some things about the Universe, but lunar experts are the first to admit they don't have all the answers when it comes to our Moon. This episode explores the theories behind Lunar Transient Phenomena that have left scientists stumped for centuries; takes to the Canadian waters to see how the Moon effects our planet through tides; and dusts off some age-old myths and weighs arguments that without our Moon, humanity may not even exist.

Cosmic Holes 12/04/2007

Cosmic Holes

Premiere Date: 12/04/2007

Today, we know black holes exist, and now scientists are trying to confirm that other holes lurk in hyperspace. Our infinite cosmos could contain a variety of "holes" such as black, white, "mini" and wormholes. White holes are the reverse of black holes; instead of matter being sucked into it, matter is ejected out. Wormholes are gateways in the fabric of space and time. They are included in Einstein's field equations as possibilities for their existence. Neither white holes nor wormholes have ever been found. Learn about new discoveries including, colliding binary black holes, intermediate black holes and manufacturing mini black holes.

Alien Planets 11/27/2007

Alien Planets

Premiere Date: 11/27/2007

Have planet hunters finally found proof of other Earthlike worlds? Astronomers have now discovered over two hundred alien worlds, beyond our solar system, that were unknown just a decade ago. Discover planets that rage with fiery hurricanes and bizarre planets covered by water so dense that it forms a kind of hot ice. Among these weird worlds, Earth actually seems like the oddball with the right conditions for life.

TVPG

Alien Galaxies 07/31/2007

Alien Galaxies

Premiere Date: 07/31/2007

To know our place in the universe take a look far, far away to the realm of Alien Galaxies. Our galaxy is one of hundreds of billions in the universe. The Milky Way consists of more than a billion stars, our sun being only one of them. Take a view of the universe through the Hubble Space telescope and go back almost all the way to the Big Bang. Cutting-edge computer graphics are used to bring the universe down to earth to show what life would be like on other planets, and to imagine what life forms might evolve in alien atmospheres.
