Find out what is being done to prevent the end of the world from threats from outer space such as comets and asteroids. Also discussed are apocalyptic scenarios.

Take a ride through the formation of the third planet from the Sun, Earth. A survivor of one of the most violent neighbourhoods in the universe, learn how earth was created and discover what creatures hold clues to how life began. What evil forces threaten the demise of Earth?

Today, we know black holes exist, and now scientists are trying to confirm that other holes lurk in hyperspace. Our infinite cosmos could contain a variety of "holes" such as black, white, "mini" and wormholes. White holes are the reverse of black holes; instead of matter being sucked into it, matter is ejected out. Wormholes are gateways in the fabric of space and time. They are included in Einstein's field equations as possibilities for their existence. Neither white holes nor wormholes have ever been found. Learn about new discoveries including, colliding binary black holes, intermediate black holes and manufacturing mini black holes.

The series highlights the major events which have shaped the Earth's history and allowed life to flourish. Follow Dr Stewart's personal journey to some of the most remote places on the planet. The atmosphere is Earth’s protective layer, cloaking us in a warm, oxygen-rich embrace and shielding us from the cold hostility of space. It acts as a natural greenhouse, keeping the Earth 51 degrees Fahrenheit warmer than it would otherwise be. Yet the atmosphere is also full of contradictions. It’s immensely powerful but at the same time highly sensitive. It’s destructive, yet it shelters us. It was created in part by the planet’s first organisms, and it continues to be essential for life.

This scientific detective tale tells the story of a remarkable group of pioneers who wanted to reach the ultimate extreme: absolute zero, a place so cold that the physical world as we know it doesn't exist, electricity flows without resistance, fluids defy gravity and the speed of light can be reduced to 38 miles per hour. Absolute zero became the Holy Grail of temperature physicists and is considered the gateway to many new technologies, such as nano-construction, neurological networks and quantum computing. The possibilities, it seems, are limitless. The first episode Chronicles the major discoveries leading towards the mastery of cold, beginning with King James I's court magician, Cornelius Drebbel, who managed to air condition the largest interior space in the British Isles in 1620. Other stories will include the first "natural philosopher," Robert Boyle, a founder of the Royal Society in Great Britain; the Grand Duke Ferdinand II de Medici's involvement in the creation of the first thermometer; the establishment of the laws of thermodynamics by three young scientists, Sadi Carnot, James Joule and William Thomson; and Michael Faraday's critical achievement in liquefying several other gases which set the stage for the commercial application of cold to refrigeration and air conditioning.

Helvetica is a feature-length independent film about typography, graphic design and global visual culture. It looks at the proliferation of one typeface (which celebrated its 50th birthday in 2007) as part of a larger conversation about the way type affects our lives. The film is an exploration of urban spaces in major cities and the type that inhabits them, and a fluid discussion with renowned designers about their work, the creative process, and the choices and aesthetics behind their use of type.
The film encompasses the worlds of design, advertising, psychology, and communication, and invites us to take a second look at the thousands of words we see every day.
Interviewees in Helvetica include some of the most illustrious and innovative names in the design world, including Erik Spiekermann, Matthew Carter, Massimo Vignelli, Wim Crouwel, Hermann Zapf, Neville Brody, Stefan Sagmeister, Michael Bierut, David Carson, Paula Scher, Jonathan Hoefler, Tobias Frere-Jones, Experimental Jetset, Michael C. Place, Norm, Alfred Hoffmann, Mike Parker, Bruno Steinert, Otmar Hoefer, Leslie Savan, Rick Poynor, and Lars Müller.
