Just days away from the beginning of the Southern Hemisphere’s spring, Antarctica’s Inexpressible Island and the Northern Foothills Mountains were illuminated by a glimmer of sunlight from a low angle when the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this image on September 16, 2009. The seaward slopes of the mountains are gleaming white, and they cast long shadows inland over the Nansen Ice Sheet. Terra Nova Bay appears in shadow.
