Attack 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.

Super 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.

The 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?

How 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.
24 min
When Will Time End
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.

The Incredible Journey of Apollo 12
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.

Supermassive Black Hole in the Milky Way Galaxy
Thick dust and blinding starlight have long obscured our vision into the mysterious inner regions of our Milky Way galaxy. And yet, the clues have been piling up that something important, something strange is going on in there. Astronomers tracking stars in the center of the galaxy have found the best proof to date that black holes exist. Now, they are preparing to capture the first direct image of a supermassive black hole.

Venus: Death of a Planet
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?

Is the Universe Infinite?
Explore the biggest question of all. How far do the stars stretch out into space? And what's beyond them? In modern times, we built giant telescopes that have allowed us to cast our gaze deep into the universe. Astronomers have been able to look back to near the time of its birth. They've reconstructed the course of cosmic history in astonishing detail.

Mysteries of a Dark Universe
Cosmology has been turned on its head by a stunning discovery that the universe is flying apart in all directions at an ever-increasing rate. The scientists who made this discovery were awarded the Nobel Prize in Physics.

The Most Powerful Objects in the Universe
What are the energy extremes that define our universe? And how much power can the cosmos wield? Climb a ladder of increasingly powerful events, from frigid gas clouds to nuclear explosions, and travel out to the seething environments of black holes. Find out where Earth fits in the vast power scales of the cosmos.
24 min
Birth of a Black Hole
Spy satellites first saw these brief but extremely bright flashes of light in the 1960s. For three decades, gamma ray bursts for deep space were one of the persistent mysteries in all of science. It took a revolution in high-energy astronomy to prove that they are the distant birth cries of newborn black holes.
