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.

Where do you look to glimpse the birth of a solar system like ours? Our sun is thought to have formed along with a range of stellar siblings. This star cluster likely moved out on its own, bound by gravity, in what astronomers call a "Moving Group."

The episode of Cosmic Journeys explores the intersection of paleoclimate and current climate science. Through its turbulent history, Antarctica has played an important role in the evolution of planet Earth. This role will likely continue as a warming global climate begins to eat away at the ice sheets that cover the continent. The fate of the world as we know it is linked to the fate of Antarctica.

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.

12th Aug 2009
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.

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?
S1 Ep7

10th Nov 2009
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.

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.

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.

Did Mars long ago develop far enough for life to arise? If so, does anything still live somewhere underground? The search for answers has revealed the forces that long ago doomed the Red Planet.
S1 Ep11
8th Jan 2010
What is the search for Earth-like planets telling us about our place in the cosmos? Is our Earth one of countless life-bearing worlds strewn about the galaxy, or is it a rare Garden of Eden in a barren universe?
S1 Ep12

9th Jun 2010
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?
S1 Ep14

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.

23rd Jun 2016
Planet hunters have detected nearly 5000 confirmed and candidate planets beyond our solar system. Most sun-like stars, it seems, are ringed with giant planets that crowd their parent stars and leave no room for planets like ours. The old theories about planetary formation are giving way to a new one defined by fierce gravitational battles and titanic collisions. How did Earth manage to survive?
S1 Ep37
13th Nov 2017
A startling collision in an ancient galaxy slews Earth's largest telescopes to a spot in the Hydra constellation. Two rapidly spinning neutron stars have violently merged to form a possible black hole. And, for the first time, astronomers see its electromagnetic flash and hear its gravitational thunder as they watch new elements being born.
