- People hypothesize about how the human race can be wiped out.
- This graphics intensive mega-series takes you on a backwards timeline to see what stood, lived, fought and died in your backyard hundreds, thousands, even millions of years ago.
- 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.
- 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.
- Scientists discuss 10 different ways of destroying the Earth; including Venus to Earth impact, the Big Burn, Stop the Spin, Black Holes, Turn off the Gravity, Anti-Matter Annihilation, Parallel Worlds Collide.
- 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.
- 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.
- We earthlings have what may be a unique opportunity in all the universe to view a stellar corona during a total solar eclipse. And while a solar eclipse is rare even on Earth, other eclipses are incredibly common despite the near perfect alignment required. In addition to the solar and lunar eclipses we are all familiar with this program looks at interplanetary and interstellar eclipses
- 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!
- Even millions of years ago, it was always Bigger in Texas. Scimitar toothed cats, the largest ocean-going reptile ever to exist, and armadillos as big as a car... in Prehistoric Dallas.
- Here in Denver, 65 million years ago, Tyrannosaurus Rex fought Triceratops in a battle to the death, and the Terminator Pig savaged anything in its path.
- Sabertooth cats once prowled LA just blocks away from the Oscar's Red Carpet. Duckbilled dinosaurs basked in California's famous surf-until they were attacked by fast and agile super-predators. And underneath it all, the ground moved...
- Mastodon's once trampled down Fifth Avenue, sea scorpions were part of the prehistoric freak show on Coney Island, and some of the world's first Dinosaurs roamed where the Giants now play.
- Prehistoric Washington D.C. was full of dinosaurs, and flying reptiles with 30-foot wingspans terrorized the skies over the National Mall. That was before it was Ground Zero, site of an asteroid impact that wiped out all life...
- 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.
