From space, we follow elephants struggling through drought, reveal unknown penguin colonies from the colour of their poo, and discover strange ice rings that could endanger seals.

From space, Earth’s surface is covered in wonderful shapes. Wombats dig burrows across the Australian outback and elephants in in the Congo clear an opening in the forest.

From space Earth is a kaleidoscope. Turquoise plankton blooms trigger a feeding frenzy; China turns yellow with rapeseed flowers; and mysterious green lights appear in the ocean.

Cameras in space show that Earth is changing rapidly. Cities sprawl while forests and glaciers shrink. But in Tanzania locals have regenerated the landscape to save chimpanzees.
