Why can you see the river Nile from space?
The ethereal glow along the river comes from the high population concentration in communities along the banks. The clusters of lights make it easy to see where people congregate. Nighttime photos of Earth taken from space give us an intriguing perspective on activities on the planet’s surface.
Why does the Nile river light up at night?
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).
Does the Nile river flow north?
The Nile River flows from south to north through eastern Africa. It begins in the rivers that flow into Lake Victoria (located in modern-day Uganda, Tanzania, and Kenya), and empties into the Mediterranean Sea more than 6,600 kilometers (4,100 miles) to the north, making it one of the longest river in the world.

What river can be seen from space?
