The hit nature series Planet Earth has returned to BBC One. It shows amazing shots of animals and landscapes. This is an Arctic Grey wolf
Animals aren't the only stars - this is a spectacular shot of an iceberg at the South Pole. The lights in the sky are the aurora australis, or Southern Lights
Sometimes it's not the big things that are amazing - like this beautiful field of flowers in Namaqualand
The show gives you a new angle on familiar things - like this polar bear hunting seals...
You can really see how harsh the Arctic is in this aerial shot....
But would you risk swimming this close to one of nature's most dangerous beasts?
This fantastic shot shows the Okavango delta in Botswana...
While this cute fella is an Indian pygmy hog
Me first! Chinstrap penguins dive into the Antarctic waters - looks a bit chilly!
African elephants wallow in the mud
While these elephants get dangerously close to lions
An astounding view of little auks in Svalbard in the Arctic circle
What could this ring of bubbles be? Amazingly it's how whales hunt for their food...
Humpback whales release the bubbles to scare krill, shrimp-like creatures, to the surface
And there's lots more to come in the later episodes, like this sunflower sea star in California
