BBC Four - The Sky at Night, The Billion Pixel Camera

A look at the Gaia space telescope, which will help answer questions about the Milky Way.

A visit to the factory that made the Gaia space telescope, which will help answer questions about the Milky Way, including what lies at its centre.

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.
