A vast range of snowy mountains are seen from a NASA P-3B airplane on March 21 during a data-gathering flight between Thule, Greenland and Fairbanks, Alaska.
The photo was captured by Christy Hansen, a scientist and project manager of NASA's Operation IceBridge, an airborne science mission studying Earth's polar ice. Over the course of the mission, Hansen and her team of scientists recorded data on polar ice sheets while flying over sea ice near the Arctic circle.
