An urban sprawl engulfs San Francisco Bay in a sea of lights. The three bridges Oakland Bay Bridge, San Mateo Bridge and Dumbarton Bridge glow as straight lines connecting the coasts. From top right going clockwise, freeways pass through Oakland, Hayward, Fremont, San Jose, Palo Alto, Redwood City, San Mateo and San Francisco.

The bright lights of the cities are themselves surrounded by natural parks. Past the coastal Eastern Bay Regional Parks to the right, the cities of Pleasanton and Walnut Creek keep the dark wilderness at bay with their street lighting. To the left, apart from the Half Moon Bay Airport on the coast, the blackness of the Pacific Ocean prevails. This image was taken on December 23, 2012 from the International Space Station.

The European Space Agency developed an automatic camera tripod that compensates for the speed of the Space Station flying at 28,800 km/h to take sharper pictures at night.
