A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before.
Many satellites are equipped to look at Earth during the day, when they can observe our planet fully illuminated by the sun. With a new sensor aboard the NASA-NOAA Suomi National Polar-orbiting Partnership (NPP) satellite launched last year, scientists now can observe Earth's atmosphere and surface during nighttime hours.
The Earth is never really dark. It twinkles with lights from humans and nature.
This video shows the animation of Earth at Night using the Satellite Data. It shows the images of The Lights of London, India Diwali Lights, Hurricane Sandy, Fires in Siberia and power outages in Washington DC area."
