The Milky Way: Island of Light

S1, E3: Professor Brian Cox continues his epic exploration of the cosmos by exploring the faint band of light that sweeps across the night sky - our own galaxy, the Milky Way. The Sun is just one of almost 400 billion stars that form this vast, majestic disk of light, our own home in the universe. We've longed to understand our galaxy's secrets since the time of the ancient Greeks, yet it's only very recently, thanks to a cutting edge space telescope, that we're finally able to reveal the Milky Way's dramatic history and predict its cataclysmic future.
