Tristan da Cunha Islands, South Atlantic Ocean
Called it the remotest island on Earth, Tristan da Cunha sits in the center of the South Atlantic Ocean 2,778 kilometers from the Cape of Good Hope in South Africa, the nearest mainland point, and 2,334 kilometers from St. Helena, the island that is its closest neighbor. Of the four islands that make up the group, only the largest—Tristan da Cunha—is occupied. The islands are volcanic in origin, and the volcanic peak of Tristan da Cunha is clearly visible in this image. The volcano forms a brown circle in the center of the island. The small islands shown here are Inaccessible and Nightingale. The Moderate Resolution Imaging Spectroradiometer ( MODIS ) on NASAs Aqua satellite acquired this image on December 20, 2003.
