What On Earth

Watching us from space, satellites orbit the Earth at 27,000 kilometres an hour, capturing images of our world that are both breathtaking and bizarre. This unique perspective reveals objects that seem to make no sense, and phenomena that defy explanation and force the question, What on Earth is that? Using state of the art technology, satellites find structures and cities lost for thousands of years.

Some of the mysterious anomalies featured this season include strange mounds in Transylvania which historians believe might pinpoint the location of Vlad the Impaler, the bloodthirsty tyrant who was the inspiration for Dracula; an unlikely presence in the eye of a mega storm which has scientists baffled; and a satellite passing over the Canadian Rockies captures an extraordinary image of shimming lake, filled with over 300 individual, multi-coloured pools, which locals believe has magical healing powers.

Experts and witnesses investigate each of these unusual images, analysing the sites on the ground as What on Earth? goes in search of answers to try and unravel these mysteries captured from space.
