Photo: Southwestern Saudi Arabia at Night

This image, taken last month from the International Space Station, shows the coastline of southwestern Saudi Arabia during night. The three brightly lit spots at top left are the cities of Jeddah, Mecca and Taif. The bright yellow-orange lighting in the middle of the image marks highways that parallel the trend of Asir Mountains, while the two bright yellow spots below it are cities of Abha and Khamis Mushait.
