Ancient Troy was once a mythical city, known only through
the text of Homers Iliad. In 1870, however,
the German archeologist Heinrich Schlieman discovered the
ruins of Troy (and several cities above and beneath it) in
northwest Turkey. He located the city by scrutinizing the
text of the Iliad, and laboriously exploring the area on foot.
Modern scientists and archeologists use high technology
such as satellite imagery to aid their search for ancient historical sites. This image of the ruins of Troy from the IKONOS satellite uses four meter resolution color data.

Commonly known as “the oldest city in the world,” Jericho is an important historical, cultural, and political center located northwest of the Dead Sea. This astronaut photograph illustrates the city center, and the original settlement mound of Tell es-Sultan. Total distance across the image is approximately 8 kilometers (5 miles). Two large refugee camps are located to the northwest and south of the city center. The high building density of the refugee camps contrasts sharply with the more open city center and irrigated fields (green polygonal patches) of Jericho, and illustrates one of the physical consequences of the ongoing Israeli-Palestinian conflict in the region.
