- Astronomer Carl Sagan leads us on an engaging guided tour of the various elements and cosmological theories of the universe.
- Examines the theory that aliens have landed on Earth in ancient times and were responsible for many of mankind's oldest mysteries. Hosted by Rod Serling.
- This 50 minute documentary focuses on the writers for the pulp magazines of the 20s, 30s, 40s and early 50s and the stories they told that were the basis or inspiration for many of today's iconic movies. Featured interviewees include Ray Bradbury and Frederick Pohl, who got their start churning out fiction for the pulps before obtaining fame through their novels, as well as editors such as John Gunnison of Adventure House and bookstore owners such as Otto Penzler.
- Comedian Rich Hall takes a journey to the place built on a tectonic fault line that still deigns to call itself the Land of Dreams - California.
- Describes how schools will benefit by using the Internet. This video may be freely copied and distributed for educational uses. Produced by the Imaging Technology Branch of NASA Ames Research Center. Audience: Grade 4 to Adult
- NASA Ames Research Center is developing telepresence that will allow astronaut-scientists to range widely and freely in their first explorations of the red planet. It uses many of the same control techniques developed for virtual reality.
- Teachers talk about how the Internet contributes to their classroom including joining online projects and enhancing curriculum units. Explores student security. Provides advice on using the Internet as a teaching tool.
- The unique features of Earth's moon and the processes that shaped it are described. Past theories of the Moon's formation are also presented.
- Take a high performance ride through the formation of the third planet from the Sun, Earth. A survivor of one of the most violent "neighborhoods" in the universe, learn how earth was created and discover what creatures hold clues to how life began.
- New discoveries regarding the Outer Planets are creating a fundamental rethinking of our solar system. Uranus is a toxic combination of hydrogen, helium and methane. Scientists speculate that the planet was knocked on its side after colliding with another body. Neptune's largest moon, Triton, is cold and barren, but some scientists speculate that liquid water might exist under Triton's icy surface. If this is proven true, Triton could be the home to one of the biggest discoveries of all time. Cold and inhospitable, Pluto completes one orbit around the solar system every 248 years. 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 kind of life forms might evolve in alien atmospheres.
- Various phenomenon observed on earth, both real and perceived, are linked to the moon. Explanations for these phenomenon are presented.
- Could we be unique in the universe or is there another planet similar to earth somewhere in the cosmos? Is it possible that Alpha Centauri, our nearest star, is home to another earth-like planet? Earth sized planets have been hard to find, but indirect methods are coming on line to give scientists a good survey of how many such bodies may be in the universe.
- It sounds like a Hollywood blockbuster: a deadly asteroid is on a collision course with Earth. But in reality, it's only a matter of time before a giant space rock threatens to wipe out civilization. An asteroid took out the dinosaurs sixty-five million years ago. Are we next? This episode analyzes the threat and explores the many ways--from a nuclear bomb to ingenious new technology
- Last century, earthquakes killed over one million, and it is predicted that this century might see ten times as many deaths. Yet when an earthquake strikes, it always takes people by surprise. So why hasn't science worked out how to predict when and where the next big quake is going to happen? This is the story of the men and women who chase earthquakes and try to understand this mysterious force of nature. Journeying to China's Sichuan Province, which still lies devastated by the earthquake that struck in May 2008, as well as the notorious San Andreas Fault in California, Horizon asks why science has so far fallen short of answering this fundamental question.
- 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.
- This program traces the history of the discoveries of planetary rings. The composition and the physics of the formation and stabilization of rings are explained.
- Professor Brian Cox questions whether we are alone in the universe. There might be more planets than stars in our galaxy - but will we find a second Earth?
- The Moon is a stabilising force for Earth, enabling life to exist here. But it is receding and moving away faster each year. When it recedes 10% more, life as we know it will be wiped out.
- In 1908 something felled millions of trees over 1000 square miles in Siberia, without leaving a trace. Many believe an asteroid was responsible. New evidence could at last solve the Tunguska mystery.
- This program considers the likelihood that intelligent life exists elsewhere in the universe and the prospects that it may inhabit a nearby planet. Then the various methods being used to look for alien intelligence are reviewed.
