Every year, thousands of objects both natural and manmade plummet through our atmosphere and crash into the Earth. These menacing messengers from the sky provide scientists with amazing insights into the natural, and not so natural, phenomena of the cosmos. From space rocks crashing through homes to cosmic boulders triggering mass extinctions to rocket parts landing on front lawns, explore objects that fall from the heavens, such as asteroids, comets, meteor showers and space debris.

Centuries ago the prophet Nostradamus had visions of the end of our modern world. Now, scholars decipher his mysterious predictions and learn of terrible tragedies and catastrophic events that threaten to annihilate global populations. Nostradamus has successfully predicted the rise of Hitler, the assassination of John F. Kennedy, the detonation of the atomic bomb, and countless other events. Many fear that the remaining unfulfilled prophecies of Nostradamus will manifest before our very eyes. At Radius Engineering in Texas, Walton McCarthy shows state of the art underground shelters to a concerned family and in South Florida, Billy Carson of Fort Terra Nova meets with a prospective client interested in joining an underground shelter community large enough to house over 350 people.

From stars, galaxies and moons to subatomic particles, black holes and invisible phenomena, discover the most bizarre, mysterious and exotic things in our universe. Learn about actual alcohol clouds floating in space that are filled with organic molecules which produce complex compounds like ethyl alcohol, the stuff we drink. Is there a hypothetical planet that exists beyond Neptune and what are pulsar planets? Mini Black Holes are a theoretical idea, but if they were to exist, some theorists speculate that they might have been produced shortly after the "Big Bang." Finally, delve into dark matter, a hypothetical form of matter that is invisible yet it exists everywhere.

Some of the world's leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our Solar System, our planet and ourselves exists many times over. These Doppelganger Universes exist within our own Universe; in what scientist now call "The Multiverse." Today, trailblazing experiments by state of the art particle colliders are looking for evidence of higher dimensions and Parallel Universes. If proof is found, it will change our lives, our minds, our planet, our science and our universe.

These giant mountain-sized boulders from space have wrought death and destruction throughout the millennia but until recently geologists could find no evidence that they had actually struck the earth. Follow the remarkable detective story that begins at Meteor Crater in Arizona as mining engineers desperately try to unearth the billion dollar iron boulder they thought was lying there. It's a detective story that also uncovers immense riches; the world's biggest nickel deposit in Sudbury, Canada, vast oil reserves in the Gulf of Mexico and a gold mine in South Africa--all the result of asteroid impacts. Evidence is also unearthed of violent impacts that decimated some of the first people to live in America. What clues do asteroids, and their smaller cousins, meteorites, hold in the formation of the early Earth and perhaps life itself?

After Custer, Thermopylae is the most famous last stand in history. In a narrow pass in Northern Greece, seven thousand Greek soldiers await an onslaught of epic proportions. They will soon face the largest fighting force ever assembled--the war machine of the mighty Persian Empire, estimated at over a million men. The Greeks are led by three hundred of the most ferocious warriors of the ancient world--the Spartans. Their leader is the fearless King Leonidas, who after this battle would be catapulted into legend. When it is over, every Spartan in the pass will have sacrificed his life for freedom. Creating a fresh visual style and using new technologies we will dramatically recreate the significant events that lead to Thermopylae and the clash of arms.

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.

An exploration of Earth's cosmic neighborhood. Looking beyond the borders of our solar system, what's nearby in our galaxy? How do the other objects in our local area influence life on Earth? And, how did Earth's place in the galaxy make it the perfect place for the development of advanced life?

Explore the world of extreme temperatures. See what happens to Pyroman, a life-size mannequin, as he is exposed to over 3,000 degrees F. Visit Underwriters Laboratories and see how common household appliances can go lethal. Follow geologists as they take lava samples from the Kilauea volcano in Hawaii. Finally, journey into a fusion facility in San Diego, California and watch as scientist's heat plasma to over 200 million degrees F in hopes of someday creating an inexhaustible power source.

On June 7, 1944, the troopship USS Susan B. Anthony transported nearly 3,000 Army and Navy men on their way to reinforce paratroopers dropped behind enemy lines on D-Day. Suddenly, two explosions hit the Susan B. just off the coast of "Bloody Omaha" in an area marked safe for passage. Stephen Ambrose called it "the German Army's greatest success of disrupting the landing of American reinforcements." Our Deep Sea Detectives John Chatterton and Richie Kohler dive this wreck 60 years later in hopes of unlocking the answers to what sank the Susan B. Anthony, and the story behind one of the most daring and amazing rescues at sea.

On June 20, 1941, the US Submarine O-9 headed out of Portsmouth, New Hampshire, and nosed below the surface carrying 33 hands and never returned. Inquiries into her sinking failed to find answers. But 60 years later, she was rediscovered. Today, our team of Deep Sea Detectives heads out with the National Undersea Research Center to take the first ever video survey of the wreck in an attempt to solve this long forgotten mystery.

In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc and 95% of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next great phase of life on earth--the age of the dinosaurs.
