    In this episode of the Hubblecast, scientists Jay Anderson and Roeland van der Marel show how they have used Hubble observations to predict the future of the Andromeda Galaxy and the Milky Way.

    Projecting the motion of Andromeda’s stars over the next 8 billion years, the astronomers now know the path that galaxy is taking through space. And it’s heading straight for us! Computer simulations based on Hubble observations show how the two galaxies will crash together in around 4 billion years’ time.
