These images contrast the sunlight Antarctica receives near spring equinox (September image) and summer solstice (December image). The low sun angles near equinox create longer shadows that reveal the ruggedness of the mountains. The higher angles near solstice shorten the shadows and brighten the landscape, while the marked reduction in sea ice exposes more of the darker ocean. Images taken by Landsat 8.
