Seeing Stars
Around the world, a new generation of astronomers are hunting for the most mysterious objects in the universe. Young stars, black holes, even other forms of life.
They have created a dazzling new set of super-telescopes that promise to rewrite the story of the heavens.
This film follows the men and women who are pushing the limits of science and engineering in some of the most extreme environments on earth. But most strikingly of all, no-one really knows what they will find out there.

Mysteries of a Dark Universe
Our knowledge of the universe comes from looking at it in various ways — different wavelengths of light, neutrinos, cosmic rays, and hopefully some day gravitational radiation. But how do we know that we are seeing everything there is? How could we determine whether there were substances in the universe not directly visible in our telescopes?
Is the universe bursting at the seams? Or is nature somehow fooling us?
The astronomers whose data revealed this accelerating universe have been awarded the Nobel Prize for Physics.
And yet, since 1998, when the discovery was first announced, scientists have struggled to come to grips with a mysterious presence that now appears to control the future of the cosmos: dark energy.
Birth Of Universe
What is exactly universe? The universe is commonly defined as the totality of everything that exists,including all physical matter and energy, the planets, stars, galaxies, and the contents of intergalactic space,although this usage may differ with the context. The term universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or nature.
Observations of earlier stages in the development of the universe, which can be seen at great distances, suggest that the universe has been governed by the same physical laws and constants throughout most of its extent and history.Our universe, the galaxies, solar system, planet Earth — land, sea, air, life — where did they come from? Astronomer Edwin Hubble believes our universe once was very tiny. Take a journey through space and time to discover how the universe was born.
The Riddle of Antimatter
Explores one of the deepest mysteries about the origin of our universe. According to standard theory, the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge. Featuring short interviews with Masaki Hori, Tokyo University and Jeffrey Hangst, Aarhus University.
Scientists are now focusing their most powerful technologies on an effort to figure out exactly what happened. Our understanding of cosmic history hangs on the question: how did matter as we know it survive? And what happened to its birth twin, its opposite, a mysterious substance known as antimatter?
A crew of astronauts is making its way to a launch pad at the Kennedy Space Center in Florida. Little noticed in the publicity surrounding the close of this storied program is the cargo bolted into Endeavor’s hold. It’s a science instrument that some hope will become one of the most important scientific contributions of human space flight.
