Epizody

1. Birth of the Moon
20. července 200924 min
Scientists have been reconstructing the history of the Moon by scouring its surface, mapping its mountains and craters, and probing its interior. Find out what the origins of the Moon can tell us about our own planet's beginnings.
2. Attack of the Sun
27. července 200924 min
Massive solar eruptions take aim at our high-tech society. 93 million miles away... an angry sun vents its rage. Dark regions, called sunspots, appeared unexpectedly on its surface... a sign of rising tension within. It had been three and a half years since the sun last erupted in fury...at the peak of an 11-year cycle of solar flare-ups.
3. Super Hurricanes
12. srpna 200924 min
Why some tropical storms erupt into monster hurricanes capable of wrecking coastlines. Can they be predicted? Hurricanes are tropical storms that feed on solar heat captured by the oceans. When conditions are right, a hurricane can release this energy in a fury of wind and rain.
4. Saturn's Mysterious Moons
20. srpna 200924 min
From the Cassini spacecraft comes one of the greatest photographic collections. Scientists are using it to uncover a trail of clues pointing to the energy sources and complex chemistry needed to spawn life.
5. The Largest Black Holes in the Universe
27. září 200924 min
Our Milky Way Galaxy is thought to harbor millions of black holes, the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?
6. How Large Is the Universe?
20. října 200924 min
The mind-blowing answer comes from a theory describing the first micro-moments of our universe. Just as scientists began to make precise measurements of the observable universe, new ideas suggest that our visible patch is an impossibly small portion of the whole.
7. When Will Time End
10. listopadu 200924 min
How long will the Universe as we know it survive? The answer depends on whether Stephen Hawking's theory about how black holes decay is right. These strange dense objects are like a clock that tick down to a distant moment when all matter and energy will dissipate into the void.
8. The Incredible Journey of Apollo 12
18. listopadu 200924 min
It's the ultimate buddy movie. Pete Conrad and Alan Bean were the second pair of Apollo astronauts to land on the moon. They combined precision with a sense of humor. But it was the rocks they picked up that would define the mission's legacy.
9. Supermassive Black Hole in the Milky Way Galaxy
9. prosince 200924 min

9. června 201024 min10.0
Long ago, from the fires of our Sun's birth, twin planets emerged: Venus and Earth. Nature draped one world in the greens and blues of life, while enveloping the other in acid clouds, high heat, and volcanic flows. Why did Venus take such a disastrous turn and Earth developed a vibrant biosphere?
14. Cosmic Energy: Cold Sparks to Black Holes
10. září 201024 min
What's the hottest place in the universe? What's it like inside a Black Hole? This video climbs the power scales of the universe, from the coldest and bleakest reaches of our galaxy on out to the hottest and most violent places known.
15. Is the Universe Infinite?
23. listopadu 201024 min
Explore the biggest question of all. How far do the stars stretch out into space? And what's beyond them?
