(Image credit: NASA Earth Observatory/Michala Garrison)The diets of penguins on Antarctica's Danger Islands can be seen from space. The image above shows pinkish-orange guano staining large sections of some of the Danger Islands, Heroína Island and Beagle Island. A colony of Adélie penguins is visible in this image captured by a drone during a research expedition to the Danger Islands. "Sea ice is such a hugely important factor in the Antarctic marine environment," said Clemson University biologist Casey Youngflesh who led a study comparing the penguins' diet and sea ice conditions.
