Cosmic Journeys
Cutting-edge stories about the origins of the universe, black holes, exploding stars, the search for ET life, and the nature of the planets. How did the universe begin? Where will it end? Are there other worlds like Earth?
Ep 1Birth of the Moon
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.
Ep 2Attack of the Sun
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.
Ep 3Super Hurricanes
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.
Ep 4Saturn's Mysterious Moons
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.
Ep 5The Largest Black Holes in the Universe
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?
Ep 6How Large Is the Universe?
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.
