In August 1977, the Big Ear Radio-telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extra-terrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the WAW signal (as an engineer wrote ‘WOW’ on the data as it came in!), it is still being considered as one of the best examples of having being sent by intelligent extraterrestrial life. But, nothing has revolutionised the search of extra-terrestrial intelligent life as much as the recent discovery by the Kepler Satellite, of thousands of Earth-like planets where life could be possible. Join the debate with this stunning one-hour documentary from 2015, as we ask Is Anybody Out There?

On July 14, 2015, the New Horizons spacecraft, one of the most advanced ever built, is scheduled to fly by Pluto to take the very first detailed images of the dwarf planet. After nine years and 3 billion miles, we will finally get a close look at this strange, icy world, but only if the craft can survive the final, treacherous leg of its journey, which could take it through a dangerous field of debris.
