ALT A blue-and-white sphere against a black background is somewhat reminiscent of the famous “Blue Marble” picture of Earth from space. With fuzzy, diffuse edges, this sphere features darker blue patches in most of the northern hemisphere facing the viewer. One, large, crescent-shaped, white patch extends along the left side of the southern hemisphere facing the viewer, and a larger, blobby, white patch covers the middle latitudes of the right side of the southern hemisphere. Lighter blue regions border these white patches in the south.
