Craig Charles: UFO Conspiracies: Seti

SINOPSE

In October 2017 astronomers at the Pan-STARRS observatory saw something strange in our solar system. An object they named 'Oumuamua', the very first observed visitor from interstellar space. It's highly unusual properties and inexplicable acceleration have left scientists divided - with some believing it was alien in origin. Tonight, Craig and Sarah take on this extraordinary case, scrutinising all available evidence before deciding whether Oumuamua was an unknown space rock or an alien rocket.
