WHAT ON EARTH?
The proliferation of satellites orbiting our planet has put more eyes on Earth's vast, unexplored areas of land and sea than ever before. Now, with these images appearing on consumer-oriented programmes like Google Earth, baffling anomalies never thought to have existed are being revealed.
The series explores and explains more mysteries: Legends of ancient giants surrounding a mysterious monument in the Holy Land; a bright pink lake potentially indicating a strange new species, and a city-sized chunk of ice suddenly disappearing in Antarctica.
With the help of experts and witnesses, the series continues to discover how these wondrous images unravel the astonishing mysteries posed by these pictures from space.
Watch What On Earth? Tuesdays at 10pm!
