NASA’s Night Photography Tracks Cracking Glaciers

Following the Larsen C ice shelf’s behavior quite closely, since one of the largest icebergs in history broke off in July, scientists came across a problem: it’s winter in Antartica and therefore it’s entirely dark. To solve the issue, NASA scientists have added a special instrument to a satellite in order to photograph and track the ice shelf. Instead of using regular light like normal cameras, this one uses a Thermal Infrared Sensor—capturing images “by measuring the differences in temperature between the water and the ice.” Find out more at National Geographic.
