"Mapping scientist Peter Fretwell says the ice around the
penguins gets very dirty because they stay in the same space in
very large colonies for months.
"Their excrement stains make them stand out from space.
"Fretwell and colleagues at the British Antarctic Survey found
this out by accident when they were looking at satellite images of
their bases and saw the stains of poop, also known as guano."
