The views from the International Space Station are out of our world. Astronaut Scott Kelly posted a photo of the Nile at night to Twitter on July 26, and it's a beauty.
The dark image shows the curve of the Earth lit up by a jagged gold trail of river, lights glittering against a shadowy background. "The #Nile at night is like a jewel," writes Kelly in the tweet.
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.
