NASA has taken some amazing pictures from space that show the amount of artificial light generated on Earth. The lights are brightest in the big cities where most of the population lives.
The photographs were taken from a satellite using a powerful new sensor, according to NASA. It’s sensitive enough to capture the light from a ship on the ocean!
