Turkish Straits - Satellite image of the Bosphorus, taken from the ISS in April 2004. The body of water at the top is the Black Sea, the one at the bottom is the Marmara Sea, and the Bosphorus is the winding vertical waterway that connects the two. The western banks of the Bosphorus constitute the geographic starting point of the European continent, while the banks to the east are the geographic beginnings of the continent of Asia. The city of Istanbul is visible along both banks.
