Europe. Satellite image of the Earth seen at 18:00 (6pm) GMT (UTC), centred on Europe. Oceans are blue and land is green and brown. City lights (yellow) in dark areas show areas of dense population, particularly in Europe (upper right). Africa (lower centre) and the Arctic (top) are sparsely populated and so have fewer lights. Image obtained using data from Landsat 5 and Landsat 7 satellites.
