Professor Brian Cox examines the hunt for extra-terrestrials, which has become a matter of serious scientific inquiry over the last few decades. Vivid animation based on data from the most successful planet hunter of them all, the Kepler space telescope, brings new worlds into view - puffy planets with the density of polystyrene, unstable worlds orbiting two suns and thousand-degree, broiling gas giants with skies whipped into titanic winds.
