They are vulnerable to climate change, as warming ocean waters melt the sea ice where they live and breed. So, it is important that we can track how many groups of penguins \u2013 called <i>colonies<\/i> \u2013 there are. This is difficult, as the areas in which they live are remote, and temperatures dip to a bitterly cold \u201350\u00b0C, making it hard for scientists to visit. Could finding them from space be the answer?\u00a0<\/p>\n<p>Individual penguins are too small to show up in satellite images, but photos taken by Sentinel-2A and 2B, which are orbiting Earth, have revealed large brown patches of ice in areas around Antarctica. Scientists realised that this is where the ice has been stained by penguin poo (the official name of which is <i>guano<\/i>)!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1280\" data-credit=\"contains modified Copernicus Sentinel data (2016), processed by ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2020\/07\/Cape_Gates_Antarctica\" data-licence=\"CC BY-SA 3.0 IGO or ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2020\/07\/cape_gates_antarctica\/22158812-1-eng-GB\/Cape_Gates_Antarctica.jpg\" alt=\"Can you see the brown patches?

Deze pingu\u00efns wonen in gebieden die waarschijnlijk worden aangetast door klimaatverandering, dus we moeten ze goed in de gaten houden en doen wat we kunnen om ze te beschermen. Sentinel-2A en 2B zijn perfect geschikt voor deze taak, want hun missie is het observeren van de gezondheid en het gedrag van onze planeet - en hoe deze voortdurend door klimaatverandering wordt be\u00efnvloed.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2395\" data-credit=\"BAS\/ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2020\/07\/Locations_of_penguin_colonies\" data-licence=\"ESA Standard Licence and Additional permission may be required\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2020\/07\/locations_of_penguin_colonies\/22158771-1-eng-GB\/Locations_of_penguin_colonies.jpg\" alt=\"Locations of penguin colonies\"><figcaption>Locations of penguin colonies<\/figcaption><\/figure>\n<p><i>Cool fact: Scientists were surprised to find that some of the new colonies live on sea ice formed around icebergs grounded in shallow water \u2013 behaviour not seen before in Emperor penguins! <\/i><\/p>\n<p><i>\u00a0<\/i><\/p>","protected":false},"excerpt":{"rendered":"<p>What kind of things do we use satellites for?
