The Night Earth map shows the lights that are visible at night on the surface of Earth. This allows:

• Observation of human-generated lights from space and light pollution caused
• Location of the spots with less light pollution, for better observation of the stars
• Real-time representation of the Aurora Borealis and Aurora Australis (Northern and Southern Lights), along the representation of where in the world is currently at day or night
• Real-time cloud coverage, to check where is it currently possible to observe the stars or the Aurora
• Night photography (only in the website, coming soon to the app)

The brightest areas of the Earth are the most urbanized, but not necessarily the most populated.

Two versions of the night images are available, captured by NASA in 2000 and 2012. These detailed maps account for 437.495 images in total, as described in the Night Earth website (http://www.nightearth.com).

Features:
• Watch the Earth at night from space
• Zoom in as much as you want so as to see more detail
• Search any location, or tell the application to focus on your current location
• Switch to the day images and compare between the day and night images
• Compare the night images captured by NASA in 2000 and 2012
• Labelled night map, to better identify countries and cities
• Track in real time in which parts of the world is day or night
• Real-time visualisation of the Aurora Borealis and Aurora Australis (Northern Lights and Southern Lights)
• Cloud coverage
• Support for devices running Android 2.3 onwards and Android TV
• Visualisation of pictures uploaded to nightearth.com
• 3D view and VR support
• Additional features are coming soon

Cities tend to grow along coastlines and transportation networks. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region.

Some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast and rivers), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya.
