NASA and the US's National Oceanographic and Atmospheric Administration (NOAA) have stitched together satellite footage to show how the Earth looks at night.
The stunning "Black Marble" video shows the bright lights over densely populated areas in developed nations like in Europe and North America.
Poorer nations in Africa are shrouded in darkness by comparison.
The lights also capture the stark contrast between wealthy South Korea and its less advanced northern neighbour, where electricity is an uncommon luxury.
In the Arabian peninsula the sky is lit up by gas flares from oil and natural gas exploration.
Meanwhile, the vast empty spaces in outback Australia outshine our urban areas thanks to bushfires.
The footage was gathered from 312 orbits of the planet by the NASA-NOAA Suomi NPP satellite, which was launched in October 2011.
