A team of intrepid palaeontologists recently discovered a lost world of dinosaurs in the unlikeliest of places — deep in the dark, snowy wilds of northern Alaska. Surprisingly, new findings indicates that dinosaurs thrived year-round and raised their young in frigid and dark conditions in the far north of the Arctic Circle.
Rappelling down giant ice cliffs bordering the Colville River, the team wields chainsaws to extract fossils frozen into the permafrost. Newly found dinosaur tracks indicates that a wide variety of species once flourished there, including herds of duck-bills, horned herbivores, pterosaurs, a new type of velociraptor, and northern relatives of T-rex.

Feast your eyes on a reconstruction of the mega-city and its amazing buildings. Alexandria, built in the middle of rancid marshland, had become in less than a century, the greatest city of the Mediterranean. An ideal position at the crossroads of east and west, and one that brought her great riches. Huge, modern, gleaming white and cosmopolitan, like no other in antiquity, it created its own identity.
While the beauty of its planning, its great arteries, its temples and its ports would be equalled only by its openness to the rest of the world. And the monumental achievements of its sovereigns, still shrouded in mystery, we'll never cease to fire our imagination for millennia to come.

Every day Astronomers are finding a new planetary system that looks pretty similar to Earth. The possibilities of life somewhere else other than Earth I think are very high. If there is life out there what would it be like? Could we talk to it? Is there anything out there like you and me? To find out, we can't just look into space, we also need to look down here.
The story of how a miraculous event transformed life on Earth into a complex interconnected food web; Astronauts and experts question other intelligent life in the universe.

They soar through the heavens, fly through the oceans and glide along land. But these are not creatures found on a wildlife safari. These are life forms from another planet. Armed with scientific fact and a little imagination, experts come together to take you on an unprecedented journey to the edges of our imagination.

Our galaxy is one of hundreds of billions in the universe. View of universe through the Hubble telescope and go back almost all the way to the Big Bang.

Travel from the inner solar system to the Kuiper Belt and explore the moons surrounding the planets of the solar system. Many of these moons that were once unknown are now on the cutting edge of astronomical study. Some burst with volcanic fury another spews icy geysers and others offer the possibility of alien life. Are these strange worlds simply hostile environments unfit for humans or do other possibilities exist? Cutting-edge computer graphics are used to bring the universe down to earth and to imagine what kind of life forms might evolve in alien atmospheres.
