A penguin colony near Cape Gates was captured in this image by the Copernicus Sentinel-2 mission on 7 November 2016. Although penguins are too small to show up in satellite images, giant stains on the ice from penguin droppings – known as guano – are easy to identify. These brownish patches have allowed scientists to locate and track penguin populations across the entire continent.
