Crete is the largest and most populous Greek island, spanning 8,300 square kilometers (3,200 square miles) and supporting a population of 620,000. A short distance northwest of Crete is a lesser-known Greek island, Antikythera. The island is comparatively tiny, spanning just 20 square kilometers (8 square miles) and supporting a human population that hovers around 50.

This view of Antikythera was acquired on September 23, 2013, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite. The landscape is typical of a small Mediterranean island, consisting primarily of open countryside and low shrubs. Steep, limestone cliffs line most of the island; flatter expanses of beach are more common on Kythira, a larger Greek island to the north. Read more
