The Bay of Rainbows

Dark, smooth regions covering the Moon's familiar face are called by Latin names for oceans and seas. This naming convention is historical, though it is ironic to those who recognize the Moon as a mostly dry, airless world. The smooth, dark areas are lava-flooded impact basins. This elegant lunar vista, a mosaic of telescopic images, looks across the northwestern Mare Imbrium, or Sea of Rains, into the Sinus Iridum, the Bay of Rainbows.
