The Bosporus (near the center of the photograph), a strait that connects the Black Sea to the north with the Sea of Marmara to the south, stands out in this low-oblique, north-looking photograph. One of the world's most strategic waterways, the strait separates European Turkey to the west with Asiatic Turkey to the east. Istanbul (formerly Constantinople), one of the great historic cities of the world, sits near the Bosporus entrance to the Sea of Marmara. Photo courtesy of NASA.
