- A middle-aged couple's career and marriage are overturned when a disarming young couple enters their lives.
- An American company inadvertently unleashes a magnetic vortex on an unprepared world.
- A rapid-fire history of our world, from the beginning of time as we know it to present day. This two-hour CGI-driven special delves into the key turning points: the formation of earth, emergence of life, spread of man and the growth of civilization--and reveals their surprising connections to our world today.
- A film about family, obligation, and the forbidding frontier that comes with leaving home.
- The wait is over! A short documentary showcasing Virus D and why this character will make you cheer for the bad guy.
- A few of the astronomical mysteries that bother scientists and the progress toward understanding them are described.
- Many considerations come to the forefront when planning space travel beyond the moon. Scientists are currently working on overcoming the many challenges and testing their solutions.
- Scientists speculate on how life originated on earth based on the range of conditions where life survives today and the conditions that existed on the early earth. They then look for those conditions, past or present, that may exist on other planets or moons.
- The many and various hazards to space travel are explained. But solving that problem better propulsion systems are need to travel anywhere beyond the moon. Some possibilities, both realistic and speculative, are described.
- Although supernovas are associated with the death of stars they also seed the universe with heavy elements that comprise rocky planets like Earth and living creatures. Due to their extraordinary brightness supernovas have a recorded history dating back 2,000 years. Although closely studied for decades their infrequency has permitted only a general understanding of their behavior until very recently. New computer models can model the major details of the explosion while new exploratory techniques reveal many more events including some truly super supernovas.
- Program presents scientists current understanding of gravity and some of the phenomenon it causes.
- If a planet has an atmosphere it has weather. And where there is weather there are storms. Our solar system is chock full of them. And the bigger the temperature extreme the bigger the storm. Which makes Earth hurricanes and thunderstorms seem rather uninteresting.
- Program examines the possible ways the universe could come to an end. The most likely scenario, eternal expansion, is expected to be rather eventful in the long term.
- Physical behavior that results from having a constant speed of light are described.
- 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.
- The challenges and risks of procreation in space are examined.
- Coronal mass ejections (CMEs) are bits of the sun thrown into space. When directed in the direction of earth they are a grave threat to civilization. How the sun's magnetic fields generate CMEs, the earth magnetic field protects us from CMSs and how our civilization's dependence on magnetic fields keeps us at risk from CMEs is explained.
- 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.
- When mankind eventually leaves the cradle of Earth and ventures forth into the uncharted territories of the cosmos, where, and what form, will our new homes take? Will they be cities under glass, entrenched in distant alien soils? Will they be gleaming metropolises hanging in orbit above our heads, or in the lonely void of space?
- A variety of cosmic events have both helpful and harmful effects on life on Earth. From the beauty of the Aurora Borealis and rainbows to the dangers of UV radiation and cosmic rays, from the miracle of photosynthesis to the thrill of a meteor shower.
- 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.
- The Universe is full of explosions that both create and destroy. The Chicxulub impact on the Yucatan peninsula, which may have wiped out the dinosaurs 65 million years ago, was two million times more powerful than the largest nuclear bomb ever detonated.
- For most, it's the deadly centerpiece of the film Star Wars. But in truth, real death stars are in the final stage of life before they explode into supernovae and, occasionally, the biggest blast in the universe--the gamma ray burst (GRB).
- Scientist speculate on future space weaponry and battle tactics.
- 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.
- They are the one-stop-shopping places for learning all about the nature and variety of stars in the Universe. They're unique, because in clusters, all the stars were born at about the same time.
- On alien planets, they rain from the sky as scalding iron. On distant moons, even at hundreds of degrees below zero, they slosh around in pristine lakes of methane. They can cover entire planets in miles-deep oceans of electrified hydrogen metal.
- Ours is a universe of energy, from powerful jets ejected from black holes to the raw nuclear fury of our Sun. But, the total amount of energy in the universe maintains perfect equilibrium--no more can be added or taken away.
- Is science-fiction rooted in science? Has science caught up to science-fiction, past and present? Is there any scientific technology that has surpassed science-fiction? This episode explores these questions and more.
- The seven wonder of our solar system are discussed: Enceladus' geysers, Rings of Saturn, Jupiter's Great Red Spot, the Asteroid Belt, Mars' Olympus Mons, the Surface of the Sun, and planet Earth.
- Scientists have taken a serious look at the possibility of time travel. Current scientific theories offer some likely prospects but engineering a working time machine, even if possible, remains a distant prospect.
- From 2006 to 2010 Mars was invaded by by several new spacecraft from its nearest neighbor, Earth. These probes have revealed numerous unexpected features of the martian surface. Several have implications for life, past and present.
- This program repeatedly hammers home the catastrophic impact of a large asteroid impact on earth. Several known large impacts of the past are recounted as well as some recent near hits. Recent and planned missions to explore objects in the asteroid belt are reviewed.
- From highly sophisticated and sensitive space telescopes that look from afar to space probes that rendezvous with celestial objects to return samples, this program looks a few of the more dramatic space explorations missions in recent years.
- It's the apocalyptic finale of our galactic neighborhood, We've now uncovered sizzling clues about our home star's violent demise. And the outcome doesn't look good for planet Earth. New cutting edge science traces the real horrors awaiting our planet as our Sun unleashes it's final fury!
- 2007–201545mTV-147.0 (66)TV EpisodeThe planets of our solar system have experienced epic catastrophes throughout their long history, both raining down from outside and bubbling up from within. We'll voyage back in time to investigate the violent events that profoundly shaped the planets, including earth itself. We'll witness stunning revelations about what transformed Mars into a barren, hostile desert...The disaster that changed Venus from temperate to hellish...The impact that blew away Mercury's mantle, turning it into a planetary core...A colossal disturbance that rearranged the orbits of the gas giants...Titanic impacts on Jupiter...And how a lost moon may finally explain Saturn's rings.
- Earth may seem like the most hospitable planet in the solar system. But look again. Startling new discoveries reveal the blue planet has been plagued by more chaos and destruction than scientists once imagined. Stand on the Earth billions of years ago as a primitive planet slams into it. Shiver as our entire globe is frozen over like a gigantic snowball. Feel the heat as mammoth volcanoes scorch the landscape and darken the sky. From a cosmic gamma ray burst frying away the ozone layer to an Everest-size asteroid slamming into the ocean, we'll reveal new information about how these unparalleled events drove life to the brink of total extinction.
