The Heart of Egypt from heaven

The heart of Egypt

here

One of the fascinating aspects of viewing Earth at night is how well the lights show the distribution of people. In this view of Egypt, the population is shown to be almost completely concentrated along the Nile Valley, just a small percentage of the country’s land area.

Scattered blue-grey clouds cover the Mediterranean Sea and the Sinai, while much of northeastern Africa is cloud-free. The thin yellow-brown band tracing the Earth’s curvature at the top of the image is airglow, a faint band of light emission that results from the interaction of atmospheric atoms and molecules with solar radiation at an altitude of approximately 60 miles (100 kilometers).
