Strange Signals From Outer SpaceJanuary 3, 2018

For centuries we've looked up at the night sky and wondered; are we alone? We've sent probes to the furthest reaches of the solar system, broadcast messages out into the depths of space, but in all those years we've heard nothing back - until now. In the last few years a mysterious signal from space has shaken astronomy to its core. This is the story of a genuine scientific mystery; the recent discovery, confirmation and on-going attempts to understand the origin of Fast Radio Bursts, enigmatic pulses from deep space that have so-far defied explanation. Taking this story as its spine, Horizon will explore humankind's quest to discover if we're alone in the Universe and our attempts to decode messages from deep space.
