The image above shows the Nile River at night from the spectacular viewpoint of astronaut Scott Kelly aboard the International Space Station (ISS).
Posted to Twitter for Kelly’s Year In Space photo project, there’s a clear view of the river aglow as it flows from its source in Burundi (upper right) down toward the cluster of light in the center, and beyond to the Mediterranean Sea.
The knots of bright light indicate where there is high population density with the brightest seen here being Cairo and Nile Delta.
The River Nile is the longest river in Africa and in the world, measuring about 6,650 kilometers long (4,132 miles). Though it is closely associated with Egypt, the river also flows through Burundi, Ethiopia, Sudan and Uganda.
