The Milky Way, our galaxy, is a magnificent sight in the night sky, but we know surprisingly little about it for certain. What is its shape? How many stars does it actually contain? What lies at its centre? The Gaia space telescope will answer these questions, being armed with the most advanced camera to leave our planet, and it will allow us to see our galaxy as we've never seen it before. The Sky at Night visits the factory in Chelmsford that made the astonishing sensor at the heart of the mission.

Here, Aleks charts how the Web is forging a new brand of politics, both in democracies and authoritarian regimes. With contributions from Al Gore, Martha Lane Fox, Stephen Fry and Bill Gates, Aleks explores how interactive, unmediated sites like Twitter and YouTube have encouraged direct action and politicised young people in unprecedented numbers. Yet, at the same time, the Web's openness enables hardline states to spy and censor, and extremists to threaten with networks of hate and crippling cyber attacks.

When man finally broke free of the Earth's gravitational pull the dream of travelling to other planets became a reality. Today scientists are proposing a bizarre array of technologies in the hope of travelling faster through space: from space craft sporting sails that catch laser beams, to propulsion engines powered by a bizarre entity known as anti-matter. Finally explore the science behind the seemingly fanciful notion of warp-drive and a theoretical particle that can travel faster than light.

Exploring the moon was humankind’s most incredible journey. Now through the magic of 3D, you can take that giant leap for yourself. Presented and narrated by Tom Hanks, Magnificent Desolation: Walking on the Moon will transport you to the lunar surface to walk alongside the 12 extraordinary astronauts who have been there to experience what they saw, heard, felt, thought and did. A romantic, inspirational depiction of the Apollo astronauts travels on the moon peppered by their quotations of their impressions.

With a little imagination, could a few terrorists sabotage a mighty nation? Perhaps even tear down modern civilization? The stability of the US, Europe, China, or any global power depends on high-speed digital communication. Our increasing dependence on digital devices and global interactivity may be placing us in grave danger. Scientists around the world are dealing with new threats such as body hacking, Trojan horse viruses, and brain-damaging Internet addiction. But what if the ultimate threat isn’t an attack on technology, but the technology? Could the final superpower be the disembodied mind of the Internet itself?

This documentary details the root causes of the systemic value disorders and detrimental symptoms caused by our current established system. This video presentation advocates a new socio-economic system, which is updated to present-day knowledge, featuring the life-long work of Social Engineer, Futurist, Inventor and Industrial Designer Jacque Fresco, which he calls a Resource-Based Economics.
