An urban sprawl engulfs San Francisco Bay in a sea of lights. The three bridges Oakland Bay Bridge, San Mateo Bridge and Dumbarton Bridge light up 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. Passed 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, aside from the Half Moon Bay Airport on the coast, blackness prevails: the Pacific Ocean.
This image was taken on 23 December 2012 by an astronaut on the International Space Station. Circling Earth at an altitude of around 400 km astronauts witness the beauty of our planet from a unique vantage point. At night, human settlements can be seen as street lighting illuminates the sky. ESA 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.
