Infrared Images Reveal Frigid, Purple Penguins

Emperor Penguins with blue bellies, green beaks, and red eyes huddle over a patch of black snow - a multicolored Antarctic landscape, as seen through the eye of an infrared thermal imager.

The psychedelic colors, which correspond to different temperatures, reveal that much of a penguin’s outer surface is cooler than the surrounding air - except, of course, for their unfeathered eyes, beaks, and feet.
