ISS033-E-007873 (27 Sept. 2012) --- Wake Island is featured in this image photographed by an Expedition 33 crew member on the International Space Station. The atoll of Wake Island is located in the central Pacific Ocean approximately 4,000 kilometers to the west-southwest of Hawaii and 2,400 kilometers to the northwest of Guam. In addition to Wake Island, the atoll includes the smaller Peale and Wilkes Island for a total land surface area of 6.5 square kilometers. Like many atolls in the Pacific, the islands and associated reefs formed around a submerged volcano. The lagoon in the center of the islands—characterized by shallow, light blue water in contrast to the surrounding darker, deeper Pacific Ocean waters—marks the approximate location of the summit crater of the volcano.
