Central Turkey dominates this north-looking panorama, with the long fingered island of Cyprus lower left, surrounded by the deep blue waters of the Mediterranean Sea. Turkey's capital, Ankara, lies just north of the white bed of a dry lake in the center of the view. The city is supplied with water from the neighboring blue lake. The coast of Syria and Lebanon appear bottom right. Man-made lakes on the upper Euphrates River in eastern Turkey appear extreme right.. According to scientists studying the STS-73 photo collection, the striking difference in visibility to north and south of Turkey suggests a pollution event over the Black Sea. Air pollution from East European industry flows down into the Black Sea basin, especially at the west end (haze top left) as shown in this view (compare clearer air top right).
