This photograph was taken through the window of NASA’s DC-8 airborne laboratory as it flew over the frozen Mid-Canadian Northwest Territories on an ARCTAS flight. An intake for an instrument that measures chemical levels in the atmosphere is just visible at the end of the aircraft’s wing. Credit: NASA/Frank Cutler
