The Incredible Story of the Milky Way Galaxy (4K)

On the darkest of nights, free from the glow of the moon and the haze of light pollution, a stunning, striking formation can be seen imprinted upon the sky. That imprint is our galaxy- the Milky Way. Our galaxy is a giant, which extends for hundreds of thousands of light years. But by measuring the motions and velocities of the stars in our neighbourhood, both their past and future trajectories can be extrapolated- revealing the history of the Milky Way.
