It kept that title until 2003, when it split in two. The break-up formed B-15J, which rests against the ice shelf. These two views show different reflective properties of the ice in the region. The image was produced by the Multi-angle Imaging SpectroRadiometer on the Terra satellite. + Full image and caption     Jet Propulsion Laboratory    California Institute of Technology
