In the blue light of the Russian Arctic, scientists captured a rare photo of a polar bear approaching a musk ox carcass Thursday (March 27).

The panoramic images give a glimpse into the life of these elusive arctic beasts, which are under threat from a changing climate.

Findings could also explain why they're invisible to night-vision goggles.

As climate change has shortened the hunting season on sea ice, polar bears have shifted to eating more land-based foods such as geese, eggs and caribou.
