It has already captivated millions, taking viewers on a spectacular polar expedition to the frozen wildernesses of the Arctic and the Antarctic.
And now the makers of the landmark BBC series Frozen Planet, bringing the natural world of the North and South Poles to the small screen, has given a tantalising glimpse of things to come with these stunning images from future episodes.
These incredible stills from the series reveal the frozen world as you have never seen it before - and may never see again, thanks to the onset of global warming.
Narrated by Sir David Attenborough, the series explores the effects of slimate change on the polar regions - and the lengths scientists are going to understand it.
The next episode in the seven-part series is to be screened on BBC 1 next Wednesday, November 2, at 9pm.

Hitching a ride: Adélie penguins on an iceberg surrounded by masses of floating ice, in western Antarctica (left), while the sky over the Arctic peninsula turns a deep shade of pink as the sun sets on another day .
Lone wolf: A rare Arctic species on Ellesmere Island in Canada. These wolves are extremely remote and unused to humans (left), while an elephant sea flicks wet sand on to its back (right) to keep cool as king penguins on the shore in South Georgia look on

Breaking free: A frozen Arctic river flows after six months locked in ice. The immense release of freshwater from the Arctic's waterways into the Arctic Ocean triggers the annual sea ice melt and fuels the mass migration of fish, birds and whales.
A nest built for two: A male Adélie penguin puts the stones in place and prepares for some female company (left) while the fur flies between these two bull seals as they battle it out for mating rights on the beach.
